you do 28 divided by 4 to get the pound of seeds per acre giving you 7
Answer:
[tex]\frac{1}{7}[/tex] acres
Step-by-step explanation:
[tex]\frac{1}{28}= \frac{y}{4}[/tex]
28 × y = 1 × 4
28y = 4
28y ÷ 28 = 4 ÷ 28

Since the radius is half of the diameter and we know that the diameter of the trashball is 4 in, we half the 4. So the radius of the trashball is 2 in.
Now plug everything in the formula.
2(3.14)(2) = 12.56.
The circumference of the trashball is 12.56 in.
Answer:
The circumference talks about the outside of the circle. So the formula for the circumference of a circle is 2πr (r stands for radius and π is pi. In this case we use 3.14 for pi).
Since the radius is half of the diameter and we know that the diameter of the trashball is 4 in, we half the 4. So the radius of the trashball is 2 in.
Now plug everything in the formula.
2(3.14)(2) = 12.56.
The circumference of the trashball is 12.56 in.

All properties that were used to simplify the following problem:
1. commutative property of multiplication
2. multiplicative inverse 3. multiplicative identity
What is commutative property of addition?
The commutative property states that an expression of the form (A + B) can be solved as (B + A) by an addition operation that does not change the end result.
The commutative property of addition says that it doesn't matter how we add two numbers, the result of the addition would be same.
For two numbers x and y, we have: x + y = y + x
Thus, if we take 3 numbers as a,b and c;
a + b + c = b + a + c = b + c + a = a + c + b = c + a + b = c + b + a
We have been given an expression;
2/7 • 53 • 7/2
53 • 2/7 • 7/2
53 • 1
53
Then all properties that were used to simplify the following problem:
1. commutative property of multiplication
2. multiplicative inverse
3. multiplicative identity

Step-by-step explanation:
Substitute 4 for y in the expression (since y = 4)
Use PEMDAS (parentheses, exponents, multiplication, division, addition, subtraction)
5 * (4)^2 - 10
= 5 * 16 - 10 Evaluate the exponent first

Solve the system. y = -x + 3 and y = 2x
the solution is (__,__).
Explain your choice of method.
Answers
Answer: (1, 2)
which means
x = 1
y = 2
Step-by-step explanation:
y = -x + 3
y = 2x
Because both equations are set equal to y, they can be set equal to each other. The equations are ready to go to use Substitution method.
Substitute.
-x + 3 = 2x
Add x to both sides.
3 = 3x
Divide by 3.
3/3 = x
1 = x
We can put the 1 in for x in either equation.
y = 2x
y = 2(1)
y = 2
Putting x for 1 into the other equation is a good check.
y = -x + 3
y = -1 + 3
y = 2
So the x and y that work in both of these equations is:
x = 1 and y = 2
The form that was asked for was ( , ).
So the answer is
(1, 2).

a=final number
p=principal balance (initial)**without interest**

t=the amount of time
p=$4000

we need to turn 2% into a decimal, to do that you divide 2 by 100 which is 0.02
now we rewrite the equation-

Find the percentage of boxes that contain 48 raisins.
A. 16%
B 20%
C 14%
D 22%
Answers
Answer:
16%
Step-by-step explanation:
first you have to find out how many boxes are in the sample (count the dots - 25) Then you do 4/25 to find the percentage because there are 4 that have 48 raisins (.16) and move the decimal point to the left 2 (multiply by 100)
Answer:
a
Step-by-step explanation:
4 boxes are full of 48 raisins. 25 boxes total.
4/25 = 0.16
Convert 0.16 into a percentage by multiplying by 100.
0.16*100 = 16
so it should be 16%, correct me if wrong though.

A. 7 ft
B. 8 ft
C. 49 ft
D. 576 ft
Answers
Plug in some values
a^2 + (24)^2 = (25)^2
a^2 + 576 = 625
a^2 = 49
a = 7
So, A.
A^2 + 24^2 = 25^2
A^2 = 625 - 576
A^2 = 49
Square root of 49 is 7!

What is the surface area of the triangular prism?
I need answer ASAP
Answers
Answer: 81 ft^2
Hello! The surface area of the rectangular prism will follow this process:
Right triangle area: (1/2)bh
So that 6ft (4.5ft) = 27ft^2/2; though when one multiplies that by 2 (as there are two right triangles), we get a surface area of 27ft^2.
For the rectangle's area, it's slightly more deviated since each face is different in length: bh
Face 1 = 3ft(7.5ft) = 22.5ft^2
Face 2 = 3ft(6ft) = 18ft^2
Face 3 = 4.5ft(3ft) = 13.5 ft^2
Thus, if we add these all together (27ft^2. + 22.5ft^2 + 18ft^2 + 13.5 ft^2), we get 81 ft^2
