Can you please help me on #12 pls
And also no links
Answer:
12) Well follow the orders of operations
Parentheses
Exponents
Mulitpacation - division (left to right)
Addition - subtraction (left to right)
Well we see an exponents lets do that first
6^2=36
And basically theres these parenthesis on the side for each so really its
(8+36) / (11)
This only occurs if the number is presented like this as diviosn or a fraction.
Now we solve that
8+36= 44
44/11=4
4+7*2
Thats the final equation
Well multiply first
7*2=14
14+4=18
The answer would be 18
3h+4> 13
I will give Brainly
Answer:
h > 3
Step-by-step explanation:
3h+4>13
3h+4-4>13-4 (subtract 4 from both sides)
3h>9 (divide both sides by 3)
h>3

What is the volume of this square pyramid?
Answer:
400m^3
Step-by-step explanation:
Answer: [tex]400m^{2}[/tex]
Step-by-step explanation:
In order to solve this square pyramid's volume, we use the formula:
V = 1/3(B)(h)
Now, we plug in what we know. Since it has a square base, the sides of the base are all the same:
1/3(10*10)(12)
Now we solve:
1/3(100)(12)
1/3(1200)
400
which shows the equation y= -1/2x + 5 written standard form ?
x + 2y= 10
x - 2y=10
x+ 2y=-10
x+2y=-10
x - 2y = 10
Answer:
x + 2y = 10
Step-by-step explanation:
[tex]y = - \frac{1}{2} x + 5 \\ \\ 2y = - x + 10 \\ \\ x + 2y = 10[/tex]

Complete the equations with powers of 10
Answer:
1. x1000
2. x100
3. x10
Step-by-step explanation:
when multiplying by powers of 10 how ever many 0's are after the 1 move the decimal that many times to the right
example:
411.92x100=41192
notice 2 0's after the 1 so i move the decimal 2 times to the right

Lila covered 55 ft squared of her back yard with 3/4 of a load of sod. She has 3 loads of sod in all. If she wants to cover all 250 ft squared of her yard, does she have enough sod?
Answer:
More sod is needed
Step-by-step explanation:
Well we know that 3/4 of a bag of sod covers 55 ft^2 then if we divide 55 by 3 we get 18.3333 we take that and multiply by 4 to get 73.333 or the amount one bag of sod can cover
73.333*3 cuz 3 bags of sod is 220 ft^2
She needs more sod

Maria needs to be at the airport terminal at 12:10. it will take 2 and 1/2 hours to drive to the airport from her home, and a further 20 minutes to park and get to terminal. give your answer as a time in the 24 hour clock
Answer:
Maria needs to start at 9:20 in order to make it to the terminal.
Step-by-step explanation:
2:30 + 0:20 = 2:50. 12:10 - 2:50 = 9:20.
If a cone has a height of 8 inches and a side measurement of 10 inches, what is the radius of its base?
Answer:
The radius of its base is 6 inches
Step-by-step explanation:
The radius of the base of a cone r , the slant height of the cone l and the height of the cone h forms a right triangle, with the slant height being the hypotenuse of the right triangle
Mathematically, since we have a right triangle, we can find the radius of the base by the use of Pythagoras’ theorem
According to Pythagoras’ theorem; the square of the hypotenuse equals the sum of the squares of the two other sides
Thus,
l^2 = r^2 + h^2
l = 10 inches
r = ?
h = 8 inches
10^2 = r^2 + 8^2
100 = r^2 + 64
r^2 = 100-64
r^2 = 36
r = √(36)
r = 6 inches
Not sure if i got this right?
Answer:
The effect it will have on the volume is;
The volume will be 8 times larger
Step-by-step explanation:
The dimensions of the given prism are;
The length of the prism, l = 5 in.
The breadth of the prism, b = 5 in.
The slant height of the prism, = 4 in. by 5 in.
The height of the prism, h = 7 in.
The shape of the prism = Parallelepiped
The volume of a parallelepiped = Area of Base × Height of the prism
The base area of the parallelepiped = The length × Breadth of the parallelepiped
∴ The base area of the given parallelepiped = 5 in. × 5 in. = 25 in.²
The volume of the given parallelepiped, V₁ is found as follows;
V₁ = 5 in. × 5 in. × 7 in. = 25 in.² × 7 in. = 175 in.³
When a scale factor of 2 in applied to the dimensions of the prism, we have;
The new volume, V₂ = 2 × 5 in. × 2 × 5 in. × 2 × 7 in.
∴ V₂ = 2 × 2 × 2 × 5 in. × 5 in. × 7 in. = 8 × 5 in. × 5 in. × 7 in. = 8 × V₁
Therefore;
V₂ = 8 × V₁
The volume of the image of the object, V₂ after applying a scale factor of 2 is 8 times larger than the volume of the object, V₁.
Ordan is cutting a 2 m 2 m2, start text, space, m, end text by 1 1 4 m 1 4 1 m1, start fraction, 1, divided by, 4, end fraction, start text, space, m, end text piece of rectangular paper into two pieces along its diagonal. Find the area of each of the pieces. m 2 m
Answer:
5/4 m²
Step-by-step explanation:
Jordan is cutting 2 m by 1 1/4 m piece of rectangular paper into 2 pieces along its diagonal.What is the area of each of the pieces.
Length of the rectangular paper = 2m
width of the rectangular paper = 1 1/4m
Area of a rectangle = Length × width
= 2 × 1 1/4
= 2 × 5/4
= (2 * 5)/4
= 10/4 m²
Area of a rectangle = 10/4 m²
Diagonal divides the rectangle into 2 equal pieces
Divide area of the rectangle by 2
Area of each piece of the diagonal = Area of the rectangle / 2
= 10/4 m² / 2
= 10/4 ÷ 2
= 10/4 × 1/2
= (10*1) / (4*2)
= 10/8
= 5/4 m²
Area of each piece of the diagonal = 5/4 m²

What is the measure of angle z in this picture?
Answer:
z = 137 degrees
Step-by-step explanation:
Angle 43 and angle z make a straight line, which is 180 degrees
43+z = 180
Subtract 43 from each side
43+z-43 = 180-43
z =137

Part A: If Angle A and Angle B are vertical angles, what is value of x
A. 8
B. 10
C. 35
D. 28
Answer:
A. 8
Step-by-step explanation:
Since ∠A and ∠B are vertical, we can create the equation: 40 = 5x.
40 = 5x
There is only one other thing we need to do, and that's divide by 5.
40/5 = x
x = 8
The value of x in this case is 8, which is A.
