4 Indira makes a wooden box without a lid. All the faces of the box meet at
right angles. Indira plans to paint all surfaces of the box, including the
inside and outside. The interior of the box has length 13 in., width 8 in., and
depth 7 in. Indira can cover up to 1,350 in.? with
5 cup of paint. Will she
need more than 5 cup of paint to cover the box? Explain how you know.
Considering the surface area of the rectangular box, it is found that since it is of 502 in² < 1,350 in², she will not need more than 5 cups of paint.
What is the surface area of a rectangular prism?The surface area of a rectangular prism of length l, width w and depth d is given by:
S = 2(lw + ld + wd).
In this problem, we have that the dimensions, in inches, are given by l = 13, w = 8, d = 7. Hence, the surface area in in² is given by:
S = 2(13 x 8 + 13 x 7 + 8 x 7) = 502 in².
Since the surface area of the box is of 502 in² < 1,350 in², she will not need more than 5 cups of paint.

Answer:
C) b ≤ 3Step-by-step explanation:
The endpoint of the graph is the midpoint between 2 and 4, so it is 3.
This point is included since indicated as full circle.
The graph includes the line to the left of 3:
b ≤ 3 is the correct oneSelect the correct answer from the drop-down menu. consider this population data set: 4, 6, 7, 11, 12, 18, 26, 23, 14, 31, 22, and 12. the values 11, 31, 22, and 12 constitute a random sample drawn from the data set. the sample mean is more than the population mean by .
The correct answer from the drop-down menu is 3.5.
What is the mean value?The mean is the average of the numbers. It is easy to calculate add up all the numbers, then divide by how many numbers in the data set.
Therefore the population mean is the sum of the 12 data set values divided by 12
4 + 6 + 7 + 11 + 12 + 18 + 26 + 23 + 14 + 31 + 22 + 12 = 186.
Therefore the population mean
= 186/12
= 15.5.
The sample mean is given by the sum of the 4 sample values divided by 4
11 + 31 + 22 + 12
Sum = 76.
Therefore the sample mean
= 76/4
= 19.
The sample mean is more than the population mean by
= 19 - 15.5
= 3.5.

A survey on healthy choices was given to gym members at Work It Out. The results showed that 90% of its members drank protein shakes. Of the members who drank protein shakes, 30% took weight-loss medication whereas only 10% of members who did not drink protein shakes took weight-loss medication. What is the probability that a gym member does not take weight-loss medication?
Answer:
63%
Step-by-step explanation:
First, create an easy number to start being able to grasp the concept.
Let us start with 100 members of "Work it Out"
90% drank protein shakes, which translates to 90 people.
30% of 90 people took weight loss medication, this is equal to 27 people. The 10% of the members that didn't take protein shakes (10) took weight loss medication. Add 10 to 27, then subtract from 100 to get the people that don't use weight loss medication. This gets us 63, then put over the total number of members to get 63%.

Shaquil needs to borrow $400. the loan company charges him $80 in fees for the loan. shaquil calculates that the annual percentage rate (apr) on his loan is 250%. approximately what is the term of shaquil’s loan? a. 7 days b. 29 days c. 46 days d. 73 days please select the best answer from the choices provided a b c d
The term of shaquil's loan will be 29 days approximatly.
We have given that,
Principle amount (p) = $400
Rate (r)= 250% = 2.5
Interest = $80
t = time (in days) = t/365
What is the formula simple interest?
[tex]I=prt[/tex]
[tex]r=\frac{I}{rt}[/tex]
[tex]2.5 = \frac{80\times 365}{400\times t}[/tex]
[tex]t= \frac{80\times 365}{400\times 2.5}[/tex]
[tex]t=\frac{73}{2.5}\\ \\t=29.2[/tex]
t = 29.2
t = 29 days
Therefore option (B) is correct.
Therefore the term of shaquil's loan will be 29 days approximatly.

Factor the following:
y^2-3y-40
3x62+10x+3
Answer:
Below in bold.
Step-by-step explanation:
y^2 - 3y - 40
To factor this we need 2 numbers whose product is -40 and whose sum is -3. These are -8 and +5. so the factors are:
(y - 8)(y + 5).
3x^2 + 10x + 3
To factor this we need 2 numbers whose product is (3*3) = +9 and whose sum is +10. These are +9 and +1 so we write:
3x^2 + 9x + x + 3
Factor by grouping:
= 3x(x + 3) + 1(x + 3)
= (3x + 1)(x + 3).

What number should be subtracted from (3/4+-1/3) to get 1/4
Answer:
5/6
Step-by-step explanation:
( 3/4+1/3) = 3 × 3/ 4 × 3 + 1 × 4/ 3 × 4 = 9/12 + 4/12 = 9+4/ 12 = 13/ 12 = 1 1/12
13/ 12 - 1/ 4 = 13/ 12 - 1 × 3/ 4 × 3 = 13/ 12 - 3 / 12 = 13 - 3 / 12 = 10 / 12 = 10 ÷ 2 / 12 ÷ 2 = 5/6
13/ 12 - 5/ 6 = 13/ 12 - 5 × 2/ 6 × 2 = 13/ 12 - 10/ 12 = 13 - 10/ 12 = 3/ 12 = 3 ÷ 3/ 12 ÷ 3 = 1/4

i honestly dont know how to answer 8+h over 10 = 1 how?
Answer:
h = 2
Step-by-step explanation:
8+h / 10 = 1
Multiply both sides by 10 to remove the denominator
10 * (8 + h / 10) = 1 * 10
8 + h = 10
Subtract 8 from both sides
8 - 8 + h = 10 - 8
h = 2

If the zeros of a quadratic function, F, are -2 and 4, what is the equation of the axis of symmetry of F
Answer:
x=1
Step-by-step explanation:
if the zeroes are (-2,0) and (4,0), then the axis of symetry is going to be right in the middle of those two, with the graph reflected equally on either side.
so you get:
(4-2)÷2=1
therefore the equation of the axis of symetry is x=1
