Answer:
14
Step-by-step explanation:
8 + 3e
e = 2
substitute in the given value
8 + 3(2)
simplify
8 + 6
14
Answer: 14
Step-by-step explanation: Here, we have the expression 8 + 3e
and we want to evaluate the expression when e = 2.
To evaluate an expression, we simply plug the
value of the variable into the expression, and solve.
So here, since e = 2, we have 8 + 3(2).
3(2) is equal to 6 so we have 8 + 6, which is equal 14.
It’s a good idea to get into the habit of using parentheses
when substituting numbers in for variables.
So the value of our expression when e = 2 is 14.
solve this please!!!!

The roots of a quadratic equation are 5 and 2/3. If one of the two factors is x-5, what could be a second
factor?
Explain your reasoning.
Answer:
Step-by-step explanation:
Given the roots of quadratic equation to be 5 and 2/3, the two factors are x-5 and x-2/3.
The variable in question are both subtracted from the root given to get the actor of the quadratic equation or polynomial. We can get the resulting quadratic function by multiplying both factors together as shown;
(x-5)(x-2/3)
= x²- 2x/3 -5x +10/3
= x²-(2x-15x)/3+10/3
= x²-17x/3 +10/3
Multiply through by 3
= 3x²-17x +10 = 0
The resulting quadratic equation for both factors will be 3x²-17x +10 = 0 and the other factor is x-2/3

A secretary earns $9 per hour and worked a total of 41 hours last week. She earns double time for work beyond 40 hours. Calculate her total pay.
Answer:
378$
Step-by-step explanation:
40 × 9 = 360 so her hours are multiplied by her money she gets by the hour
Next
9 × 2 = 18 Because she worked 1 extra hour she earned double
Finally you do
360+18 = 378$
How do I subtract decimals from whole numbers?
Answer:
Just use long subtraction by expanding the decimal places of the whole number. This is done by adding a point, and enough zeros to it to match the number of decimal digits in the other number (digits after the decimal point).
12345678
i.e: 5 - 2.48374827, 2.48374827 has 8 decimal digits, so add 8 zeros after the point.

Find the circumference of a circle with radius, r = 12m.
Give your answer in terms of π.
Answer:
C = 24 pi meters
Step-by-step explanation:
The circumference of a circle is given by
C = 2 * pi *r
C = 2 * pi * 12
C = 24 pi meters
Answer:
24π
Step-by-step explanation:
The circumference of a circle uses this equation: [tex]2\pi r[/tex]. Just like the last question I answered, you want to give the answer in terms of pi, so we aren't going to multiply pi.
The question gives us the radius so we don't have to divide anything, we plug in r with 12 as is.
[tex]C=2\pi 12[/tex]
Now multiply the 2 and the 12 so it will be in terms of pi.
[tex]C=24\pi[/tex]
In terms of pi, the circumference is 24π.

s + 6a ≥ 300
4, s, + , a, ≥ 1600, , s, + 6, a, ≥ 300
4s ≥ 1600

s + a ≥ 300
4, s, + 6, a, ≥ 1600, , s, + , a, ≥ 300
6a ≥ 1600
4s ≥ 300
Answer:
pretty sure its c
Step-by-step explanation:
4s+6a represents how much money the tickets cost per person and they want to raise at least 1600 dollars
s+c represents how many people and they want at least 300 people to attend.
not sure what that last bit is but c is the most logical answer

1. Layne rode his bike from Point A to B by
using Cherry Street. How much further would
his trip have been if he took Orange Drive
and Peach Avenue instead?
PLEASE HELP ASAP ILL GIVE BRAINLIEST DUE TODAY!!
Answer:
cherry street is 85 yards, while orange dr. and peach ave. is 113 yards, meaning that cherry st. is 28 yards faster
Step-by-step explanation:
(85 x 85) - (77 - 77) = 1296
square root of 1296 is 36
77 + 36 = 113
113 - 85 = 28
this means that cherry st. is 28 yds faster
using the Pythagorean Theorum
The distance that Layne would have to travel further if he took the given paths is required.
If Layne took Orange Drive and Peach Avenue instead his trip would be 28 yards longer.
Pythagoras theoremc = Length of Cherry st. = 85 yards
a = Length of Orange dr.
b = Length of Peach av. = 77 yards
The angle between orange drive and peach avenue has been assumed to be [tex]90^{\circ}[/tex].
We need to find the sum of the distances of the paths orange drive and peach avenue.
So, we need to find the length of orange drive.
Applying the Pythagoras theorem
[tex]a^2+b^2=c^2\\\Rightarrow a=\sqrt{c^2-b^2}\\\Rightarrow a=\sqrt{85^2-77^2}\\\Rightarrow a=36\ \text{yards}[/tex]
The distance traveled when orange drive and peach avenue is taken is
[tex]36+77=113\ \text{yards}[/tex]
The extra distance traveled
[tex]113-85=28\ \text{yards}[/tex]

In applications, most initial value problems will have a unique solution. In fact, the existence of unique solutions is so important that there is a theorem about the existence and uniqueness of a solution. Consider the initial value problem dy/dx=f(x,y), y(x) = yo. If f and f/y are continuous functions in some rectangle R= {(x,y):a Use the method of separation of variables to find the solution to dy/dx =y1/3? Begin by separating the variables. dy= dx
Answer:
The answer is "[tex]\bold{ y^{ \frac{2}{3}}} = \frac{2}{3}x + c} \\\\[/tex]"
Step-by-step explanation:
By using the given method we separate the above-given variable and find the solution of:
[tex]\bold{\frac{dy}{dx} =y^{\frac{1}{3}}}[/tex]
Solution:
[tex]\to \frac{dy}{dx} =y^{\frac{1}{3}}\\\\\to \frac{dy}{y^{\frac{1}{3}}} =dx\\\\\to y^{ - \frac{1}{3}} dy =dx\\\\[/tex]
Integrate the above value:
[tex]\to \int y^{ - \frac{1}{3}} dy = \int 1 dx\\\\\\\to \frac{y^{ - \frac{1}{3} +1}}{- \frac{1}{3} +1} = x \\\\ \\\to \frac{y^{ \frac{-1 +3}{3}}}{ \frac{-1+3}{3} +1} = x \\\\\\\to \frac{y^{ \frac{2}{3}}}{ \frac{2}{3} +1} = x \\\\\\\to \bold{y^{ \frac{2}{3}}} = \frac{2}{3}x + c} \\\\[/tex]

What is 67.5% as a fraction in simplest form
Answer:
27/40
Step-by-step explanation:
The percentage 67.5% as a fraction in simplest form is 16.875/25.
To convert 67.5% to a fraction in simplest form, we divide the percentage by 100 and simplify if possible.
67.5% can be expressed as 67.5/100.
To simplify the fraction, we divide both the numerator and denominator by their greatest common divisor (GCD), which is 2:
67.5/100 = (67.5 ÷ 2) / (100 ÷ 2)
= 33.75/50
We can simplify this fraction further by dividing both the numerator and denominator by their GCD, which is 2:
33.75/50 = (33.75 ÷ 2) / (50 ÷ 2)
= 16.875/25
Since there is no common factor other than 1 between the numerator and denominator, the fraction 16.875/25 is already in its simplest form.

Answer:
3. 4 N
4. 3√2 N
Step-by-step explanation:
Again, these are "special triangles," so you already know the ratios of the side lengths.
3. The given sides have the ratio 2 : 3.464 = 1 : 1.732 = 1 : √3, so the remaining side finishes the special triangle ratios 1 : √3 : 2 = 2 : 3.464 : 4.
T = 4 N

0.34 is 10 times as great as what number?
Answer:
0.034
Step-by-step explanation:
the opposite of multiplication is division. 0.34 divided by 10 is 0.034. you can also figure this out by moving the decimal to the left once.
0.34 is 10 times greater than 0.034.
What is a decimal ?A decimal is represented by a dot or a point it separates the whole part and the fractional part of the given number.
According to the given data
0.34 is 10 times as great means we have to divide 0.34 by 10
which is
= (0.34/10)
= 0.034
∴ 0.34 is 10 times greater than 0.034.
We can also do this by simply moving the decimal to one left of the digit.
For example if given a.cb and we have been asked what number is 100 times greater than a.bc we can simply move the decimal to the right by 2 place then it will be abc.
