Step-by-step explanation:
An electrician charges $40 for each hour plus a $25 surcharge. The electrician raises the charges for each hour by $5. Write an equation that represents the new cost c of a job that take h hours
Answer:
c = 45h + 25
Step-by-step explanation:
The only difference between what the electrician used to charge and what he/she charges now is an increase of $5. Therefore, instead of charging $40 he is now charging $45. Using this new information we can create the following equation to calculate the total cost of a job. We do this by multiplying the cost per hour ($45) by the total number of hours (h) and then adding the surcharge.
c = 45h + 25

Define the variables for the situation. Then enter an equation.
The pencils were divided into 8 groups of 2.
p = (select)
Enter an equation:
=
8
Answer:
p = 16/8 = 2
Step-by-step explanation:
We know that the pencils were divided into 8 groups of 2.
Then the total number of pencils is equal to 8 (the number of groups) times 2 (the number of pencils in each group)
8*2 = 16
The total number of pencils is 16.
Then the operation of dividing 16 pencils into 8 groups is written as:
16/8
And we know that this is equal to 2, then the operation is:
16/8 = 2.
Then the equation is:
p = 16/8 = 2
where p represents the number of pencils in each group.

What is the volume of a cone with a diameter of 6 units and a height of 16 units?
The diameter of the raw cookie is 2 1 2 inches. After baking the cookie, the diameter is 5 1 2 inches. By what factor does the cookie expand? A 236% B 220% C 45% D 42%
Answer:
120%
Step-by-step explanation:
Given that,
The diameter of the raw cookie is 2 1/2 inches i.e. 5/2 inches
After baking the cookie, the diameter is 5 1/2 inches i.e. 11/2inches
We need to find by what factor does the cookie expand.
[tex]x=\dfrac{5\dfrac{1}{2}-2\dfrac{1}{2}}{2\dfrac{1}{2}}\times 100\\\\=\dfrac{\dfrac{11}{2}-\dfrac{5}{2}}{\dfrac{5}{2}}\times 100\\\\=120\%[/tex]
So, the cookie will expand 120%.
Answer:
220%

The length of a rectangle is 2m longer than its width.
If the perimeter of the rectangle is 24m , find its area.
Answer:
35m
Step-by-step explanation:
length = 2+w
width = w
Perimeter = 2(length)+2(width)
24 = 2(2+w)+2(w) = 4+2w+2w = 4+4w
24=4+4w
4w=20
w=5
width =5
length = 2+5 = 7
Area = (length)(width) = 5(7) = 35m
Simplifying rational exponents
1) a^-8/5
2) (9b^4)^2/3
3) (8x^5)5/7
PLEASE I NEED HELP!!!!!!
Answer:
1/a^8/5 for the first, 9b^8/3 for the second, and 8x^25/7 for the third
Step-by-step explanation:
1) With neg exponents, you can just take it and flip it, and make the exp pos i.e. 1/a^8/5
2) When there is an exponent outside of parenthesis of a number with an exponent, you multiply the exponents together i.e. 9b^8/3
3) The same applies to this as the 2nd, we just multiply to get 8x^25/7

0.65 ? 68%
Answer:
1.09
Step-by-step explanation:
0.65 + Percentage increase =
0.65 + (68% × 0.65) =
0.65 + 68% × 0.65 =
(1 + 68%) × 0.65 =
(100% + 68%) × 0.65 =
168% × 0.65 =
168 ÷ 100 × 0.65 =
168 × 0.65 ÷ 100 =
109.2 ÷ 100 =
1.092 ≈
1.09
Answer:
1.09
Step-by-step explanation:
Rounded to maximum 2 decimals:
0.65 increased by 68% ≈ 1.09

Ribbon is sold by the metre.
1 metre of ribbon costs 55p.
Kate bought 16 metres of ribbon and paid with a £10 note.
How much change did she get?
Answer:
Change received by Kate = £1 and 20p
Step-by-step explanation:
Given that:
Cost of 1 meter ribbon = 55p
Ribbon bought by Kate = 16 meters
Cost of 16 meters = 16 * 55 = 880p
Amount paid by Kate = £10 = 1000p
Change received= 220p = £1.20
Change received = £1 and 20p
Hence,
Change received by Kate = £1 and 20p

Answer:
I belive it would be 2:6:3
Step-by-step explanation:
I think this is right
Answer:
4:6:3
Step-by-step explanation:
If 2 red = 3 blue & 2 blue = 1 green,
We have to find a common denominator for blue2×3 = 6, therefore multiply the ratio for red and blue by 2. 2×2 = 4 red and 2×3 = 6 blue.To find green, we want our numerator to be 6, since it represents the blue. We know green is 1/2 of blue so it's 3.4 red, 6 blue, 3 green

how many real zeros will x^2+19=8x+3
Answer:
The solution to the quadratic equation is:
[tex]x=4[/tex]
Thus, there will be one real zero.
Step-by-step explanation:
Given the equation
[tex]x^2+19=8x+3[/tex]
Subtract 19 from both sides
[tex]x^2+19-19=8x+3-19[/tex]
Simplify
[tex]x^2=8x-16[/tex]
Subtract 8x from both sides
[tex]x^2-8x=8x-16-8x[/tex]
Simplify
[tex]x^2-8x=-16[/tex]
Add (-4)² to both sides
[tex]x^2-8x+\left(-4\right)^2=-16+\left(-4\right)^2[/tex]
[tex]x^2-8x+\left(-4\right)^2=0[/tex]
Apply perfect square rule: (a-b)² = a² - 2ab + b²
[tex]\left(x-4\right)^2=0[/tex] ∵ [tex]x^2-8x+\left(-4\right)^2=\left(x-4\right)^2[/tex]
so solve
[tex]x-4=0[/tex]
Add 4 to both sides
[tex]x-4+4=0+4[/tex]
Simplifying
[tex]x=4[/tex]
Therefore, the solution to the quadratic equation is:
[tex]x=4[/tex]
Thus, there will be one real zero.
Akhil pours a total of 6/2 cups of milk as shown in the model which expression could be used to represent the total cups of milk
Full question:
A recipe calls for 2 cups of milk for every 6 1/4 cups of flour. If you increase the flour to 43 3/4 cups, how many cups of milk will you use?
Answer:
14 cups of milk
Step-by-step explanation:
The question can be rephrased how many 6 1/4 cups of flour can we get in 43 3/4 cups of flour so that we find how many cups of milk required
6 1/4 = 25/4.
Also, 43 3/4 = 175/4
We could now divide 175/4 by 25/4 to get how many 6 1/4 cups of flour are in 43 3/4 cups of flour = 175/4 / 25/4 = 175/4×4/25= 7
This means that we have seven 6 1/4 cups of flour, therefore we require 7×2 = 14 cups of milk (given that we require 2 cups of milk for every 6 1/4 cups of flour)
