Answer:
1,if Noah is 15 his cousin is 8 or 96 months
2, and when Noah's cousin is 132 months or 11 years old Noah will be 18
3,n-[[7]12]=age of Noah's cousin
Step-by-step explanation:
1,15-7=8
1 part 2, 8*12=96
2,132/12=11
2 part 2,
11+7=18
3,n-[[7]12]=age of Noah's cousin
4,n+[7/12]
if n=18
18+[7/12]
or
18+0.5833=18.5833

you do the same for -9 and -5, the midpoint for those being -7, I hope this helps
Find the surface area of a sphere with a radius of 2√2 feet.
94.5 square feet
100.5 square feet
25.1 square feet
35.5 square feet
Answer: 100.5 square feet
Step-by-step explanation:
To find : surface area of sphere with radius of [tex]2\sqrt{2}feet[/tex]
The formula used to calculate surface area of sphere is = [tex]4\times \pi\times r^2[/tex]
where r is the radius of sphere.
Putting the values we get:
surface area of sphere = [tex]4\times 3.14\times (2\sqrt{2}feet)^2=100.5square feet[/tex]
Thus the surface area of a sphere with a radius of 2√2 feet is 100.5 square feet

John plans to practice piano at least 2 1 2 212 hours this weekend. If he practices 1 1 6 116 hours on Saturday and 1 1 4 114 hours on Sunday, will he meet his goal?
Answer:
No
Step-by-step explanation:
The computation is shown below:
In weekend, at least [tex]2 \frac{1}{2}[/tex] hours should be practice i.e. 2.5 hours
But actual he would be practice
[tex]= 1 \frac{1}{6} + 1 \frac{1}{4}\\\\= \frac{7}{6} + \frac{5}{4}\\\\= \frac{14 + 15}{12} \\\\= \frac{29}{12}\\\\= 2.4167[/tex]
So he would not able to meet his goal

A group of friends were working on a student film. They spent all their budget on props and equipment. They spent $693 on props, and 37% of the total budget on equipment. What was the total budget for their student film?
Answer:
$1100
Step-by-step explanation:
Let the total budget = b
amount spent on props + amount spent on equipment = total budget
If 37% of the budget was spent on equipment
The percentage spent on props = 100% - 37% = 63%
63% of the total budget is $693
the above sentence presented as an equation gives :
63/100 x b = 693
to find b, divide both sides of the equation by 100/63
b = $1100
Answer:
1100

What is the equation of a line passing through two points?Let the equation of the line pass through (x₁, y₁) and (x₂, y₂).
Then the equation of the line is given as,
[tex]\rm (y - y_2) = \left (\dfrac{y_2 - y_1}{x_2 - x_1} \right ) (x - x_2)[/tex]
From the equation, the two points of Dave's line will be (0, 6) and (2, 9). Then the equation is given as,
(y - 6)[(9 - 6) / (2 - 0)](x - 0)
y = 1.5x + 6
From the equation, the two points of Andrew's line will be (0, 3) and (1, 5). Then the equation is given as,
(y - 3) = [(5 - 3) / (1 - 0)](x - 0)
y = 2x + 3
The number of hours when the amount Andrew and dave pay for the rentals be equal will be calculated as,
2x + 3 = 1.5x + 6
0.5x = 3
x = 6 hours
The number of hours when the sum Andrew and dave pay for the rentals be equivalent will be 6 hours.

Answer:
x-intercept (s):
For this case h (x) = 0
x2 - 2x - 8 = 0
(x-4) * (x + 2) = 0
x1 = 4
x2 = -2
y-intercept:
For this case x = 0
h (0) = (0)2 - 2 (0) - 8
h (0) = - 8
vertex:
We derive the equation:
h '(x) = x2 - 2x - 8
h (x) = 2x - 2
We match zero:
2x-2 = 0
x = 2/2
x = 1
We evaluate the function for x = 1
h (1) = (1)2 - 2 (1) - 8
h (1) = 1 - 2 - 8
h (1) = -9
The vertex is:
(1, -9)
axis of symmetry of the function:
x = 1
