Answer:

9

Explanation: the answer is 9 because 15 is 3 times 5 so you would have to multiply 3 by 3 to mark it to scale.

Answer:

A

Step-by-step explanation:

The formula for this type of interest is [tex]A=P(1+\frac{r}{n})^{nt}[/tex], where A is the total amount, P is the initial investment, x is the interest rate, n is the amount of times that the investment is compounded a year, and t is the amount of years. Plugging in the numbers given, you get:

[tex]A=1800(1+\frac{0.025}{2})^{2\cdot 12}=[/tex]

[tex]1800(1.0125)^{24}\approx 2425.23[/tex]

Now, she invests this into a new account, and you can set up the following equation:

[tex]A=2425.23(1+\frac{0.04}{12})^{12\cdot 7}=[/tex]

[tex]2425.23(1.0033333)^{84}\approx 3207.40[/tex], or option A.

Hope this helps!

Answer:

(-2, 9)

Step-by-step explanation:

1) Multiply each term of the top equation by two.

2(x) + 2(y) = 2(7)

2x + 2y = 14

2) Use elimination to get rid of the y's

 2x + 2y = 14

-(5x + 2y = 8)

Translates to...

    2x + 2y = 14

+ (-5x - 2y = -8)

=  -3x = 6

3) Solve for x by dividing each side of the equation by -3.

[tex]\frac{-3x}{-3} = \frac{6}{-3}[/tex]

x = -2

4) Plug in x to find the y-value

x + y = 7

-2 + y = 7

-2 + 2 + y = 7 + 2

y = 9

Answer:

The z-score associated with the upper boundary of of this price range is -0.25.

Step-by-step explanation:

It is provided that the board of directors for Cosmic Coffee wants to know the price range for the lowest 40% of drink sales.

If X represents the price range of drink sales, then

P (X < x) = 0.40

Consider that X follows a Normal distribution.

To compute the probability of a normally distributed random variable we need to first convert the raw score to the z-scores.

The formula to z-score is:

[tex]z=\frac{X-\mu}{\sigma}[/tex]

Then,

P (X < x) = 0.40

⇒ P (Z < z) = 0.40

The value of z for this probability is:

z = -0.25

*Use a z-table.

Thus, the z-score associated with the upper boundary of of this price range is -0.25.

Answer:

-0.25

Answer:

C.) f(x) = 2x^2 + 4x + 4

Step-by-step explanation:

The equation of the parabola with vertex (h,k) is y=a(−h+x)^2+k.

Thus, the equation of the parabola is y=a(x+1)^2+2.

To find a, use the fact that the parabola passes through the point (2,20): 20=9a+2.

Solving this equation, we get that a=2.

Thus, the equation of the parabola is y=2(x+1)^2+2.

TO STANDARD FORM

= 2*(x^2+2x+1)+2  

=(2x^2+4x+2)+2  

= 2x^2+4x+2+2

Answer:

The radius is 14

Step-by-step explanation:

The circumference of the circle is 28 pi

C = 2* pi *r  where r is the radius

28 pi = 2 pi *r

Divide each side by 2 pi

28 pi/2pi = 2 pi *r/2pi

14 = r

Answer:

Step-by-step explanation:

–6 − 8r = 8 − r

− 8r - r = 8 + 6

-9r = 14

r = -14/9

Answer:

r =-2

Step-by-step explanation:

–6 − 8r = 8 − r

Add r to each side

–6 − 8r+r = 8 − r+r

-6 -7r = 8

Add 6 to each side

-6+6 -7r = 8+6

-7r = 14

Divide each side by -7

-7r/-7 = 14/-7

r =-2

Answer:

[tex]2\frac{3}{4}[/tex] pounds

Step-by-step explanation:

Maggie buys 1 1/2 pounds of walnuts, 8 ounces of pecans and 3/4 pounds of almonds.

To find the total weight of nuts that she buys, let us first put all the weights in a single unit, pounds.

She buys 8 ounces of pecans.

1 ounce = 0.0625 pounds

8 ounces = 8 * 0.0625 = 0.5 pounds = 1/2 pounds

Therefore, the total weight of nuts that she buys is:

[tex]1\frac{1}{2} + \frac{1}{2} + \frac{3}{4}\\ \\\frac{3}{2} + \frac{1}{2} + \frac{3}{4} = 2\frac{3}{4}[/tex]

The nuts weight [tex]2\frac{3}{4}[/tex] pounds in all.

What does [tex]-\dfrac35>-2[/tex] indicate about the position of [tex]-\dfrac35[/tex] and −2 on the number line?

Options

negative 3 over 5 is located on the right of −2

negative 3 over 5 is located on the left of −2

negative 3 over 5 is located on the right of 0 and −2 is located on the left of 0

negative 3 over 5 is located on the left of 0 and −2 is located on the right of 0

Answer:

(A)negative 3 over 5 is located on the right of −2

Step-by-step explanation:

Given the inequality: [tex]-\dfrac35>-2[/tex]

On a number line, numbers are written from the left to the right in ascending order.

Therefore:

In the given inequality  [tex]-\dfrac35>-2[/tex] , both numbers are negative and are therefore to the left of 0.

However, since [tex]-\dfrac35[/tex] is greater than -2, it is located to the right of -2 .

The correct option is A.

Answer: Betty's daughter is 34 years old now.

Step-by-step explanation:

So Betty is currently 71. In three years, she will be 74. So she will be twice as old as her daughter at the age of 74. To find out how old Betty's daughter is in 3 years, I will divide 74 by 2, which is 37 (74/2). Finally, I will subtract the original 3 years from the 37 years of age of Betty's daughter, and I will get my answer for how old Betty's daughter is, which is 34 years old.

Answer:

60 square feet.

Step-by-step explanation:

The area to be fenced has two rectangles and one square. We add the areas of the rectangles to that of the square to obtain the total amount of fencing required.

Area of 4 × 5 feet rectangle =(4 × 5) = 20 square feet

Area of 3 × 5 feet rectangle =(3 × 5) = 15 square feet

Area of 5 × 5 feet square =(5)²  = 25 square feet

So the total amount of fencing that need to be installed is 20 + 15 + 25 square feet = 60 square feet.
