What is the surface area?
29 in
36 in
5 in
square inches
Answer:
The surface area of a rectangular prism can be calculated by adding the area of each of its six faces. The formula for the surface area of a rectangular prism with length l, width w, and height h is:
Surface Area = 2lw + 2lh + 2wh
So for a rectangular prism with length 29 inches, width 36 inches, and height 5 inches, the surface area can be calculated as follows:
Surface Area = 2 * 29 * 36 + 2 * 29 * 5 + 2 * 36 * 5
= 2,612 + 290 + 360
= 3,262 square inches
Therefore, the surface area of the rectangular prism is 3,262 square inches.

Answer:
[tex] \frac{14}{16} \: and \: \frac{13}{16} [/tex]
Step-by-step explanation:
So we have these two fractions
[tex] \frac{7}{8} \: and \: \frac{13}{16} [/tex]
Does 8 go into 16? Yes. It goes in twice because 8 times 2 is 16. That means 16 is our common denominator.
Because of that, since we multiplied 8 by 2, we will do the same to the 7. 7 times 2 is 14.
Because of that we have 14/16 and 13/16 as our answers.

Answer:
rectangle: 30 ft²triangle: 12 ft²total: 42 ft²Step-by-step explanation:
You want the area of the composite figure consisting of a rectangle and a triangle.
RectangleThe area of the rectangle is ...
A = LW
A = (5 ft)(6 ft) = 30 ft² . . . . rectangle area
TriangleThe base of the triangle is the difference in length of the horizontal segments:
b = 9 ft -5 ft = 4 ft
The area is given by the formula ...
A = 1/2bh
A = 1/2(4 ft)(6 ft) = 12 ft² . . . . triangle area
Total areaThe area of the figure is the sum of the areas of its parts:
total area = rectangle area + triangle area
total area = 30 ft² +12 ft²
total area = 42 ft²
__
Additional comment
The area of this trapezoid can also be found using the trapezoid formula:
A = 1/2(b1 +b2)h
A = 1/2(9 ft +5 ft)(6 ft) = 42 ft²
The rectangle is shown in the figure as 5 ft wide and 6 ft tall. It does not matter which of these dimensions you call the length and which you call the width. Their product is the same either way.
From the graph of y = f(x), how do we obtain the graph of y = f(x+1) +3?
Select one:

b. Shift to the right by 1, and then shift up by 3
c. Shift to the left by 3, and then shift up by 1
d. Shift to the left by 1, and then shift up by 3
e. Shift to the right by 3, and then shift up by 1
It is a translation of 3 units up and one unit to the left, then the correct option is D.
How do we obtain the graph of y = f(x+1) +3?For any function y = f(x), we can define:
A vertical translation of N units as:
g(x) =f(x) + N
if N > 0, the translation is up
if N < 0, the translation is down.
A horizontal translation of N units as:
g(x) =f(x + N)
if N > 0, the translation is left
if N < 0, the translation is to the right.
Here we have:
g(x) = f(x + 1) + 3
So we have a translation of 1 unit to the left and 3 units up.
The correct option is d.

55 hours in one week with $15 per hour. What’s gross pay, assuming overtime is time and a half?
Answer:
Step-by-step explanation:
If you work 55 hours in one week and earn $15 per hour, your gross pay before taking into account any overtime can be calculated as follows:
Gross pay = 55 hours x $15/hour = $825
If you work overtime, which is time and a half, the additional pay can be calculated as follows:
Overtime pay = ($15/hour x 1.5) x (55 hours - 40 hours) = ($22.50/hour x 15 hours) = $337.50
So, the total gross pay including the overtime pay is:
Gross pay = $825 + $337.50 = $1,162.50
Therefore, the total gross pay for working 55 hours in one week at $15 per hour, with overtime pay calculated as time and a half, is $1,162.50.
What is (-3,2),(4,-3) and (-5,-4) rotated 90° counterclockwise
The coordinates after the rotation of 90° will be (-2, -3), (3, 4), and (4, -5) respectively.
What is geometry rotation?Each point in a figure is transformed into a rotation by rotating it a specific amount of degrees around another point.
Precession, nutation, and intrinsic rotation are the names of these rotations.
Shapes can be rotated by being moved around a fixed point (clockwise or anticlockwise, and by a certain number of degrees).
Although the shape will remain precisely the same, its location within the room will shift.
So, we have:
(-3,2),(4,-3) and (-5,-4)
Now, the graph then as follows.
Now, rotate them to 90°.
(Refer to the graph attached below)
Then, the coordinates after 90° rotation will be:
(-3,2) = (-2, -3)
(4,-3) = (3, 4)
(-5,-4) = (4, -5)
Therefore, the coordinates after the rotation of 90° will be (-2, -3), (3, 4), and (4, -5) respectively.

Solve for the length of the unknown side in the following right triangle. (Side AC is the hypotenuse.) Round your answer to two places, where applicable. Side AB 17, Side BC 22, Side AC ?
Answer:
27.87
Step-by-step explanation:
In a right triangle, the length of the hypotenuse can be found using the Pythagorean theorem, which states that the sum of the squares of the two shorter sides is equal to the square of the length of the hypotenuse.
Using the given sides, we can write the equation:
AB^2 + BC^2 = AC^2
Substituting the given values, we have:
17^2 + 22^2 = AC^2
Simplifying the left side, we get:
289 + 484 = AC^2
773 = AC^2
Taking the square root of both sides, we find:
AC = √773 = 27.87
Rounding to two decimal places, the length of side AC is approximately 27.87.
If y varies directly as x, and y=6 when x=15, find y when x=2.
A.) 4/5
B.) 4
C.) 5
d.) 5/4
Answer:
Option A: 4/5
Step-by-step explanation:
If y varies directly as x written as y ∝ x, this can be written as an equation:
y = kx where k is a constant
Since y = 6 when x = 15:
6 =k · 15
6 = 15k
15k = 6
k = 6/15 = 2/5
The equation beocmes
y = (2/5) x
Therefore when x = 2,
y = (2/5) x 2 = 4/5
Option A: 4/5

3. Write the expression as a simplified rational expression. Show your work.
Answer:
5/1/6+ 1/X + 1
Answer:
(1/x)+31
Step-by-step explanation:
To simplify the expression
5/(1/6) + 1/X + 1,
we need to first simplify the fraction 5/(1/6):
5/(1/6) = 5 * 6/1 = 30
Now we can substitute this value back into the expression:
30 + 1/X + 1
To combine the last two terms, we need to find a common denominator, which is X:
30X/X + 1/X + X/X
Simplifying the numerator:
30X + 1 + X
Combining like terms:31X + 1
so the simplified rational expression is (1/x)+31
A swimming pool has 500 gallons in it and is leaking. The change in the amount of water in the pool is -3 gallons per hour. How many gallons would the pool contain after 6 hours?
Amount of gallons of water after 6 hours is 482 gallons.
What is Volume?Volume of a three dimensional shape is the space occupied by the shape.
Given that,
Initial volume of the swimming pool = 500 gallons
The change in the amount of water in the pool is -3 gallons per hour.
Each hour, the volume of the pool is decreasing by -3 gallons.
Change in the amount of water in 1 hour = -3 gallons
Change in the amount of water in 6 hours = -3 × 6 = -18 gallons
After 6 hours,
Volume of the pool = 500 - 18 = 482 gallons

Percentage of people who buys less than 2 tires = 13%
Percentage of people who buys none = 6%

Answer:
Salary with $3300 raise per year:
t (years) Salary
1 $69300
5 $82600
10 $95900
15 $1092000
20 $1225000
Salary with 4% raise per year:

1 $68640
5 $83833
10 $102219
15 $124869
20 $152947
Note: The calculations for the 4% raise are done as follows:
Year 1: 66000 * 1.04 = $68640
Year 5: 66000 * 1.04^5 = $83833
Year 10: 66000 * 1.04^10 = $102219
Year 15: 66000 * 1.04^15 = $124869
Year 20: 66000 * 1.04^20 = $152947
Step-by-step explanation:
2000 Paul was twice as old as his brother Biko. In 2008 Paul was only four years older than his brother. In what year was Biko born ? Select one: a. 1996 b. 1990 c. 1992 d. 1998 e. 2000
Answer:
a. 1996
Step-by-step explanation:
Let Paul's age in 2000 be P
Let Bilko's age in 2000 be B
Statement: Paul was twice as old as his brother Biko in 2000 means
P = 2B (1)
In 2008 Paul was only four years older than his brother.
Since 2008 is 8 years from 2000, both Paul and Bilko have aged 8 years
Paul's age in 2008 = P + 8
Bilko's age in 2008 = B + 8
Statement: In 2008 Paul was only four years older than his brother means
P + 8 = B + 8 - 4
P = B + 4 (2)
Given these two equations (1) and (2)
Substitute P = 2B from (1) in (2):
2B = B + 4
==> 2B - B = 4
==> B = 4
Therefore in 2000, Paul was 8 years old and Bilko was 4 years old
Bilko's year of birth = 2000 - 4 = 1996
