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

Answer:
[tex]h = \sqrt{72}in[/tex]
Step-by-step explanation:
We have a right triangle with long side of 11in and smaller sides 14in/2=7in and h.
We know that
[tex]h^2 + (7in)^2 = (11in)^2\\h^2 = 121in^2 - 49in^2 = 72in^2\\h = \sqrt{72}in[/tex]

24 - n = 6 What is n?
Answer:
n is 18
Step-by-step explanation:
Answer:
24 - n = 6
Figure out what plus 6 will give you 24.
Or add 24 and 6 and use the sum as the fill-in for n.
24 + 6 = 30.
Replace the variable.
30 (n) - 24 = 6.

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
Answer:
100.5 square ft

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

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
