Answer: 198cm
Step-by-step explanation:
We are given the dimensions of a rectangular prism;
3cm 9cm and 6cm
We are required to determine its surface area;
We need to know that;
Surface area of a rectangular prism is given by;
A = 2(WL+HL+WH)
Where L, W and H are length , width and height respectively;
Assuming;
Width is 3 cm
Length is 9 cm, and
Height is 6 cm
Then;
Area = 2 ( (3×9) + (6×9) + (3×6))
= 2(99)
= 198 cm²
Therefore, the area of the rectangular prism is 198 cm²

Step-by-step explanation:
[tex](x+4)^2=25[/tex]
[tex](x+4)(x+4)=25[/tex]
expand the brackets:
[tex]x^2+8x+16=25[/tex]
subtract 25 from both sides:
[tex]x^2+8x-9=0[/tex]
factor:

Person A can paint the neighbor's house 3 times as fast as Person B. The year A and B worked together, it took them 10 days. How long would it take each to paint the house?
Bro I don't know if I'm dumb or not but I literally can't figure this out. Please help my struggling self wcdfvrd
Answer:
A: 13 1/3 daysB: 40 daysStep-by-step explanation:
If person A can paint the house in 'a' days, then person B takes 3a days. Each day, the total amount of house painted when they work together is ...
1/a + 1/(3a) = 1/10
4/(3a) = 1/10 . . . combine terms
40 = 3a . . . . . . . cross multiply
a = 40/3 = 13 1/3 . . . . . divide by 3
A can paint the house in 13 1/3 days.
B can paint the house in 40 days.

Step-by-step explanation:
Answer:
The answer your looking for is (most likely) C.
Step-by-step explanation:
If you had a mirror on the y-axis, the reflection of the pre-image triangle would be the image. The y-axis, called the line of reflection, is the line of symmetry for the two triangles. Triangle 1 is called the pre-image, and the reflected triangle is called the image.
how do you write this in slope intercept form i don’t know
Answer: y = [tex]-\frac{2}{1.5}[/tex]x + 15
Step-by-step explanation:
Slope intercept form is written as y = mx + b, where m is the slope and b is the y- intercept.
2.00x + 1.50y = 15
1.50y = -2.00x + 15
y = [tex]\frac{-2}{1.5}[/tex]x + 15
determine the y- intercept of 3x+2y=9
Answer:
The y intercept is (0,4.5)
Step-by-step explanation:
Because the y-intercept occurs at x = 0, we can substitute this into our equation and solve for y.
3(0) +2y = 9
2y = 9
y=4.5
Answer:
[tex]\boxed{(0 , 4.5)}[/tex]
Step-by-step explanation:
→ Rearrange into y = mx + c format
2y = - 3x + 9
→ Divide everything by 2
y = -1.5x + 4.5
→ Substitute x = 0
y = 0 + 4.5 ⇒ 4.5
Find the complement of ∠DEF.
Answer: Choice B) 14 degrees
Explanation:
Complementary angles add to 90 degrees
This means the answer we're after is 90 - (angle DEF) = 90-76 = 14
Answer is B
Complement means two angles that have the sum of 90°
90 - 76 = 14
so that would mean 14° is the correct answer
For the crazy pizza portfolio I just need the formulas to prove that my pizza can fit inside the box I already have A=pi r2 now I just need the rest
To prove that the pizza fits inside the box we need the formula for the area of a square, to identify the area of the box and to know if the pizza fits inside the box.
How to calculate the area of the box (area of a square)?To calculate the area of a square we must apply the following formula:
Length of square × base of square = area of square ²According to the above, if we have a pizza with a radius of 30cm, its area would be:
A = 3.14 × 15²A = 706.5 cm²So we would need a box with a side length of at least 30cm. Its area would be:
30cm × 30cm = 900cm²
So for a 706.5cm² pizza, we need a 900cm² box.

What is dilation?Dilation is the process of increasing the size of an item without affecting its form. Depending on the scale factor, the object's size can be raised or lowered. There is no effect of dilation on the angle.
The distance between City A and City B is 200 miles. A length of 2.1 feet represents this distance on a certain wall map. Then the scale factor is given as,
Scale factor = 200 / 2.1 miles per foot
City C and City D are 3.15 feet apart on this map. Then the actual distance is given as,
Distance = 3.15 x 200 / 2.1
Distance = 1.5 x 200
Distance = 300 miles
The actual distance between City C and City D will be 300 miles.

How to find the perimeter and area of 7.7m, 2.8m, 9.7m, 4
Answer: perimeter = 26.8
area = 49.16
Step-by-step explanation:
perimeter:
Rectangle one:
add 9.7 + 9.7 + 4 + 4 because there is 4 sides = 27.4
Rectangle 2:
2.8 + 2.8 + 3.7 +3.7 = 13
Add them together: 27.4 + 13 = 40.4
area :
rectangle one:
multiply 4 x 9.7 = 38.8
rectangle two:
multiply 3.7 x 2.8 = 10.36
add them together: 10.36 + 38.8 = 49.16

here is a list 31 29 33 37 43 38 33 40 find the mode in number of list and work out on mean
Answer: Mode = 33, Mean = 35.5
Step-by-step explanation: The mode is whatever number appears the most.
To find the mode, first put the numbers in order from least to greatest.
29, 31, 33, 33, 37, 38, 40, 43
In this case, 33 appears the most, so the mode is 33.
The mean is the average of all of the numbers.
Firstly, add up all of the numbers:
29 + 31 + 33 + 33 + 37 + 38 + 40 + 43 = 284
Now that you have all of them added up, divide the final sum by the number of numbers you have in the list. In this case, you have 8 numbers.
284/8 = 35.5
Your mean is 35.5
Answer:
Mode = 33
Mean = 35.5
The mode is whatever number appears the most.
to find the mean:
add all the numbers:
29 + 31 + 33 + 33 + 37 + 38 + 40 + 43 = 284
divide that by the number of numbers you have in the list.
284/8 = 35.5
mean = 35.5
