Answer:
23
Step-by-step explanation:
Use the part/whole = %/100.
You have that whole = 115 and % = 20, so that would be:
[tex]part/115=20/100[/tex]
simplify & solve:
[tex]part/115=1/5[/tex]
multiply both sides by 115
[tex]part=115/5\\part = 23[/tex]
You can buy 12 cookies for $4. What is the unit rate for the cost of each cookie?
Answer:
$0.33 per cookie
Step-by-step explanation:
The unit rate (cost per cookie) is
$4
---------------- = $0.33 per cookie
12 cookies
Answer:
Roughly $0.34
Step-by-step explanation:
Set up an equation:
Variable x = cost of one cookie
12cookies/$4 = 1cookie/x
12/4 = 1/x
Cross multiply
12 × x = 4 × 1
12x = 4
Divide both sides by 12
12x ÷ 12 = 4 ÷ 12
1x = 4/12
x = 0.333333
x = is about $0.34

PLSSS PLSSS HELP! After an injury, Greg's doctor advises him to slowly build up to his regular workout schedule, adding a certain number of minutes to his workout time each week. According to his doctor's advice, Greg should work out for 25 minutes in week 3 and 47.5 minutes in week 6. A. For how many minutes should Greg work out in week1? How many in week 10? B. For how many minutes should Greg workout in week n? Explain your answer. Make sure to include the arithmetic sequence that can be used to find out how many minutes agree should work out in week n. Show your work.
Answer:
Week 1: 10 Minutes
Week 10: 77.5 Minutes or 1 hour and 17.5 Minutes
Week n: 10 + 7.5n
Step-by-step explanation:
Every week, Greg adds another 7.5 minutes to his workout time. Week 1 starts off with 10 minutes and continuously adds 7.5 minutes until he gets to week three, which 10 + 7.5(2) = 25 minutes.

The perimeter of a rectangle is 20 feet. The width is 4 feet less than the length. Find the dimensions of the rectangle. Then find its area.
Answer:
length = 7 ft
width = 3 ft
area = 21 sq ft
Step-by-step explanation:
let l = length
let l - 4 = width
2l + 2(l - 4) = 20
2l + 2l - 8 = 20
4l = 28
l = 7
w = 3
Area: 7 x 3 = 21

Answer:
<GHI = 135 degrees
Step-by-step explanation:
(3x + 12) + (x + 4) = 180
4x + 16 = 180
4x + 16 - 16 = 4x
180 - 16 = 164
4x = 164
4x / 4 = x
164 / 4 = 41
x = 41
3 * 41 + 12
3 * 41 = 123
123 + 12 = 135

Surface are of prisms
Answer:
Area of cube formula - A=6a2
Area of rectangular prism - A=2(wl+hl+hw)
Answer:
1. Nets
2. Surface Area
3.area
4. add
5. A= 1/2 bh
Step-by-step explanation:
Side A- 8x5 = 40 sq.m
Side B - 3x8 = 24 sq.m
side c - 5x8 = 49 sq.m
side d - 1/2 ( 3x 2) = 3
side E- 1/2 (3x2) = 3
Area of rectangular prism - 2 (wl + wh + lh)
surface area of cube = 6a^2 ( a is edge)

What is the solution set of the equation?
[tex]\sqrt{x} -18+9x=x[/tex]
9514 1404 393
Answer:
x ∈ {2.07014981016}
Step-by-step explanation:
The equation can be rewritten as ...
√x = 18-8x
x = 324 -288x +64x²
64x² -289x +324 = 0
x = (289 ±√577)/128 ≈ {2.07015, 2.44548}
Since √x must be positive, we know that ...
18 -8x ≥ 0
x ≤ 18/8 = 2.25
The larger of the above solutions is extraneous, so the solution set is ...
x ∈ {(289 -√577)/128} ≈ {2.07015}

Find the area of the shape using the formula for the area of a trapezoid:
A = 1/2(b1 + b2) · h
Where:
b1 = base 1
b2 = base 2
h = height
A = area
Plug in the given bases and height:
A = 1/2(7.5 + 2.5) · 2.5
Simplify:
A = 1/2(10) · 2.5
A = 5 · 2.5
A = 12.5 units²
Solve for x. Each figure is a trapezoid.

Step-by-step explanation:
If another sample of size 100 is taken, what is the probability that its sample mean will
be greater than 2.56 in?
Answer:
I don't know the answer to this but
Suppose we draw a sample of size n=16 from this population and want to know how likely we are to see a sample average greater than 22, that is P( > 22)? So the probability that the sample mean will be >22 is the probability that Z is > 1.6 We use the Z table to determine this: P( > 22) = P(Z > 1.6) = 0.0548.

Answer:
x=15
Step-by-step explanation:
Hello there!
The shown angles are vertical angles
if you didn't know vertical angles are congruent
That being said we can create equation
5x + 40 = 115
now we solve for x
step 1 subtract 40 from each side
40 - 40 cancels out
115 - 45 = 75
now we have 75 = 5x
step 2 divide each side by 5
5x/5=x
75/5=15
we're left with x = 15
