Answer:
360m²
Step-by-step explanation:
Surface area of Pyramid=4*Area of Triangle+Area of Square
Area of Triangle=(1/2)*Base*Height
Area of Square=Side²
Area of 4 Triangles=4*(1/2)*10*13=260m²
Area of square=10²=10*10=100m²
Total Area=260m²+100m²=360m²

The rectangle below has an area of 70 square meters.
Find the dimensions of the rectangle.
(x - 11)
(x - 8)
Answer:
The side lengths are 10 by 7
Step-by-step explanation:
The area of a rectangle is
A = l*w
70 = (x - 11)(x - 8)
FOIL
70 = x^2 -8x-11x+88
Combine like terms
70 = x^2 -19x +88
Subtract 70 from each side
0 = x^2 -19x +88-70
0 = x^2 -19x+18
Factor
What number multiplies to 18 and adds to -19
-18*-1 =18
-18-1 = -19
0=(x-18)(x-1)
Using the zero product property
x-18=0 x-1=0
x=18 x=1
But x cannot x=1 because then the side lengths would be negative
x-18 = 10
x-11 = 7
The side lengths are 10 by 7
Amanda slept for 1/3 of the day. She played with her friends for 1/5 of the day. She spent the rest of the day working on a school project. What fraction of the day did she spend working on her project
Answer:
Amanda spent 7/15 of the day working on her project.
Step-by-step explanation:
1/3 x 5/5 = 5/15 1/5 x 3/3 = 3/15 5/15 + 3/15 = 8/15 15/15 - 8/15 = 7/15which of the following could be the lengths of the sides of a triangle?
a. 1,2,1
b.2,3,1
c.3,5,4
d.7,15,7
Answer:
C
Step-by-step explanation:
The general rule is that any two leg lengths must exceed the third.
A) won't. 1 + 1 = 2. The 2 ones lay flat across the 2.
B) 2 + 1 = 3. Won't work for the same reason as A
C) works fine. Any 2 will exceed the third.
D) can't happen. 7 + 7 < 15.

two printers working together can print a 250 page book in 30 minutes. printer a takes twice as long as printer b to print the same book. how long would it take each printer working alone to print the book. let the variable x = how many minutes it takes to print the book. Using units of books/minutes, write an equation involving rates using rational functions, solve for x, and interpret the results in context.

When Anita planted a large bush in her garden, it was 5 feet tall. Now it is 40% taller. How tall is the bush now?
Answer:
7 feet
Step-by-step explanation:
the new height of the bush can be represented in percentage form as 100% + 40% = 140% = 1.40
1.40 x 5 = 7 feet
Method 2
find 40% of 5 feet
0.4 x 5 = 2
Add 5 + 2 = 7 feet

5. Which two values are NOT solutions for x in the inequality 5x + 3 > 33?
a. 5
b. 6
c. 7
d. 8
Answer:
5 and 6
Step-by-step explanation:
Given the inequality 5x + 3 > 33?
Subtract 3 from both sides
5x + 3 - 3 > 33 - 3
5x > 30
Divide both sides by 5
5x/5 > 30/5
x > 6
Hence the value of x must be greater than 6. The values that are not greater than 6 are 5 and 6. Hence 5 and 6 are not solution for x in the inequality

If each of the cubes in a Rubik's Cube represented 1 cubic inch, what would be the volume of the Rubik's Cube?
Answer:
The volume of the Rubik's Cube is 27 in^3
Step-by-step explanation:
Each face of a Rubik's Cube has 3x3 cubes, then each face has 9 small cubes.
We can think of a Rubik's Cube as 3 pieces, such that each piece has 9 small cubes on it, and the 3 pieces are: Front side, middle part, back part.
Then the total number of small cubes on a Rubik's cube is 9*3 = 27 small cubes.
Now we know that each one of these small cubes has a volume of 1 in^3
Then the volume of 27 of these cubes is 27 times the volume of a single smaller cube, then the volume of the Rubik's Cube is:
V = 27*( 1 in^3) = 27 in^3
