Answer:  D

Step-by-step explanation:

Answer:

1)

Nicole: [tex]95x+240[/tex]

Milan: [tex]125x[/tex]

2)

[tex]95x+240=125x[/tex]

Step-by-step explanation:

Question 1)

We know that Nicole opened her account with a starting amount of $240. She also puts in $95 per month.

So, we can write the following expression:

[tex]95x+240[/tex]

Where 240 represents the initial deposit of $240 and the 95x represents the $95 for x months.

Milan opened his account with no starting amount, and he's putting in $125 per month.

So, we can write the following expression:

[tex]125x[/tex]

Since he didn't put anything at the start, out initial deposit is simply 0. The 125x represents the $125 for x months.

Question 2)

We want to write an equation that shows when the two accounts will have an equivalent balance.

So, we can simply set the two expressions above equal to each other:

[tex]95x+240=125x[/tex]

And we're done!

Notes:

Let's solve for x to determine when the two accounts will have the same amount of money. Subtract 95x from both sides:

[tex]240=30x[/tex]

Divide both sides by 30:

[tex]x=8[/tex]

So, after 8 months, the amount in Nicole's and Milan's account will be equivalent.

Answer:

921.05

Step-by-step explanation:

Answer:

921.05

Step-by-step explanation:

If 19% of a number is 175, then what is 100% of that number? Setup the equation.

Solve for Y

Using cross multiplication of two fractions, we get

19Y = 175 x 100

19Y = 17500

Y = 17500

100 = 921.05

Answer: w = 110°     x = 83°     y = 87°      z = 97°

Step-by-step explanation:

∠(x - 13) and ∠w form a linear pair so their sum is equal to 180°

x - 13 + w = 180        →     w = -x + 193

∠(x + 10) and ∠y form a linear pair so their sum is equal to 180°

x + 10 + y = 180        →    y = -x + 170

∠x  and ∠z form a linear pair so their sum is equal to 180°

x + z = 180             →    z = 180 - x

∠x and ∠y and ∠w are the angles of a triangle so their sum equals 180°

x + y + w = 180

x + (-x + 170) + (-x + 193) = 180                   Substitution

                       -x + 263 = 180                    Add Like Terms

                       -x            = -83                    Subtracted 263 from both sides

                                  x = 83                      Divided both sides by -1

w = -x + 193                     y = -x + 170                     z = 180 - x

w = -83 + 193                  y = -83 + 170                   z = 180 - 83

w = 110                           y = 87                             z = 97

Answer:

z= 120, ∠x= 60°, ∠y= 50°, ∠w= 70°

Answer:

f(-2)= -4

Step-by-step explanation:

plug in -2 for every x you see in the equation.

f(-2)= -22-9(-2)

= -22+18

= -4

therefore, f(-2)= -4

Answer:

[tex]\boxed {\tt f(-2)=-4}[/tex]

Step-by-step explanation:

We are given the function:

[tex]f(x)= -22-9x[/tex]

We want to find f(-2). Therefore, we must substitute -2 in for each x.

[tex]f(-2)=-22-9(-2)[/tex]

Solve according to PEMDAS: Parentheses, Exponents, Multiplication, Division, Addition, and Subtraction.

Multiply -9 and -2.

[tex]f(-2)=-22+18[/tex]

Add 18 to -22.

[tex]f(-2)=-4[/tex]

f(-2) is equal to -4 for f(x)=-22-9x

Multiply 8 by 4.

If one cup is 8 ounces, I assume they have the same value.

Answer:

C.

Step-by-step explanation:

To get a perpendicular line, the slope will be the opposite of what you currently have. You have a slope of 2, so the opposite reciprocal slope will be -1/2. Then, you use the equation y = mx+b and substitute (2,5) for the y and the x (2 for the x and 5 for the y). This is to solve for b. Then, you have your equation! Hope this helped.

Answer:

k=11

Step-by-step explanation:

distribute

4 times k =4k

4 times -6 = -24

4k-24=20

add 24 to both sides

20 plus 24

= 44

4k=44

divide 4 from both sides

k=11

The value of k is 11

Linear equations help in representing the relationship between variables such as x, y, and z, and are expressed in exponents of one degree. In these linear equations, we use algebra, starting from the basics such as the addition and subtraction of algebraic expressions.

Given here 4(k-6) = 20

                     k-6=5

                       k = 11

Hence the value of k is 11

Answer:

Here we can take advantage of exactly the property suggested by Xisca... that is, sqrt(44)=2sqrt(11), which reduces the calculation to more accuracy with a lesser knowledge of the squares of numbers.

As a first approximation, we know that 33*33=1089, or 3.3*3.3=10.89, which is already very close to 11.  

Thus a first approximation to sqrt(44)=2sqrt(11)=2*3.3=6.6 (approximately).

To refine the calculation of sqrt(11), we use Newton's approximation, namely

a better approximation is given by 3.3 + (11 - 3.3^2) / (2*3.3) = 3.3+0.11/6.6 = 3.3+1/60

which gives

sqrt(44) = 2(3.3+1/60) = 6.6+1/30 = 6.6333,

actually accurate almost to the nearest 1/10000.

All of the above can be done mentally

For those who need help with rounding to the nearest hundredth (0.01), we drop digits AFTER the 2nd decimal, namely *.**33.  If the first digit dropped is 5 or more, add one to the last digit retained, otherwise, retain only the two digits after the decimal.  In this case, the first digit dropped is 3, so it will simply be dropped.  The final answer is then 6.63, to the nearest hundredth.

The sphere's volume with a diameter of 18 in. is 3052.08 in³.

We know that the volume of a sphere is:

[tex]V=\frac{4}{3}\pi\text{r}^{3}[/tex] --------- (i)

where V ⇒ Volume of the sphere

r ⇒ radius of the sphere

Now as per the question:

The diameter of the sphere, d = 18 in.

We know that the radius is half the diameter:

r = d/2 ---------- (ii)

Therefore, substituting the values in equation (ii),

r = 18/2

r = 9 in.

Use the value of the radius to find the Volume of the sphere:

Putting the values in equation (i),

[tex]\text{V}=\frac{4}{3} (3.14)(9)^{3}[/tex]

V = 3052.08 in³

Therefore, the volume of the sphere of diameter 18 in. rounded to two decimal places is 3052.08 in³.

The radius of the Cylindrical cup is approximately 4.44 cm.

The radius of the cylindrical cup, we can use the formula for the volume of a cylinder:

Volume = π * r^2 * h

Where:

- Volume is the capacity of the cup (780 cubic centimeters),

- π is a mathematical constant approximately equal to 3.14159,

- r is the radius of the base of the cylinder (which we need to find),

- h is the height of the cylinder (12 cm).

We can rearrange the formula to solve for the radius (r):

r^2 = Volume / (π * h)

Substituting the given values:

r^2 = 780 / (3.14159 * 12)

Calculating the value:

r^2 ≈ 19.7384

To find the radius (r), we take the square root of both sides:

r ≈ √19.7384

r ≈ 4.44 cm (rounded to two decimal places)

Therefore, the radius of the cylindrical cup is approximately 4.44 cm.

#SPJ8

Answer:

The original price is 180$

Answer:

Step-by-step explanation:

If there is a 10 percent discount, that means that this is 90 percent of the total.

So, let us find 10 percent is made up of how many dollars.

$162/9=$18 (do note that the slash sign means divide! When you write down the equation on a paper, please write the actual divide sign. Sorry for the inconvenience)

Since the original price is 100 percent, and we have 10 percent, that means we can just multiply the 10 percent by 10, to get 100 percent, as 10 times 10 is hundred.

$18x10=$180

Answer:

Step-by-step explanation:

Solubility can be defined as the ability of a solute (could be solid, liquid or gas) to dissolve in a solvent in order to produce a solution. There are several factors affecting solubility which includes (basically four) temperature, polarity, surface area of solute particles and pressure of gases. Generally, an increase in temperature leads to an increase in the solubility of a solute in a solvent. This is because an increase in temperature will increase the average kinetic energy of molecules in the solution which leads to increase interaction between the solute and solvent particles. There is a general saying of "like dissolve like" when discussing polarity. For example, organic solvents are used to dissolve organic solutes (just as petrol is used to wash grease off hands and surfaces). Hence, when the solute and solvent have the same polarity, solubility occurs easily, otherwise solubility may be difficult or may not even occur. A reduced/smaller surface area of the solute leads to an increase in solubility as this makes it easy for the solute particles to interact easily with the solvent. In gases, an increase in pressure increases the interaction between the gaseous molecules of the solute and the solvent, thus leading to an increased solubility. Pressure does not affect solubility in solids and rarely in liquids.

Here, we are required to discuss factors affecting solubility.

Factors affecting solubility include:

Temperature; solubility of a solute in a solvent increases with increase in temperature and vice versa. However, the same cannot be said for a gases whose solubility decreases with increase in temperature.

Polarity is another factor that affects solubility. In which case, polar solutes dissolve in polar solvents while non-polar solutes dissolve in non-polar solvents. The phenomenon of polarity follows the "like dissolves like" principle.

However, it is important to note that pressure does not have effect on solubility. As such, the solubility of a solute-solvent combination is not affected by pressure.

The molecular size of the solutes also has an effect on the solubility. This is so because, the larger the molecular size of the solute, the more difficult it is for the solvent molecules to surround it during solubilization.

Increasing the surface area of a solute further increases the rate of solubilization and hence the solubility. Another way to enhance the solubility of a solute-solvent combination is by stirring to enhance solubility.

[tex]\huge\boxed{(1, -3)}[/tex]

Step-by-step explanation:

In order to find the solution to this system of equations, our goal is to get one variable on one side of the equation.

With the equations d [tex]10x-2y=16[/tex], and [tex]10x-2y=16[/tex], we know that we can multiply [tex]10x-2y=16[/tex] by -1 and the x terms will cancel out (as 10 - 10 = 0).

[tex]-1(10x-2y=16) = -10x + 6y = -16[/tex]

Now we add this equation to the first.

[tex]10x+9y=-17[/tex]

[tex]-10x+2y=-16[/tex]

_______________

[tex]11y=-33[/tex]

Divide both sides by 11 and we get [tex]y=-3[/tex].

Now that we know the value of y, we can substitute it inside an equation and find the value of x. Let's substitute it inside  [tex]10x-2y=16[/tex].

[tex]10x-2(-3)=16\\10x+6=16\\10x=10\\\\x=1[/tex]

So x = 1.

Answer:

x =4

Step-by-step explanation:

x/y = 1/2

(x + 2) / (y + 1) = 2/3

Cross multiply the first equation

2x = y

Put that value for y into the second equation.

(x + 2) / (2x + 1) = 2/3              Cross multiply

3(x + 2) = 2(2x + 1)                   Remove the brackets.

3x + 6 = 4x + 2                        Subtract 3x from both sides

6 = 4x - 3x + 2

6 = x + 2                                  Subtract 2 from both sides

6-2 = x

x = 4
