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
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]

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.
Given the figure below, find the value of x and y. Thank you!

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

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.
Solve the equation. 36^6x-1 = 6^5x

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.

. Frosty Snacks sells ice cream in a cylindrical cup and in cones.
The small cup of ice cream has a height of 4 inches and a radius
of 2 inches. The small cone has a height of 6 inches and a
diameter of 5 inches. How much more ice cream will fit into a
small cup than a small cone? Use 3.14 for pi.
Answer:
10.99 in^3
Step-by-step explanation:
Steps to determining the answer
determine the volume of the cylinderdetermine the volume of the conefind the difference in volumesvolume of a cylinder = nr^2h
n = 3.14
r = radius
3.14 x 4 x 2² = 50.24 in³
Volume of a cone 1/3(nr^2h)
n = 22/7
r = radius
A radius is half of the diameter = 5/2 = 2.5 in
h = height
(1/3) x 3.14 x 2.5² x 6 = 39.25 in³
difference = 50.24 - 39.25 = 10.99 in³

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

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
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
When you find one more
than a number, only the
ones digit will change.

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
