Answer:
Peter has 6 dollars.
Step-by-step explanation:
The ratio is 1:3, meaning Jane has 3x more money than Peter. Or, Peter has 1/3 as much money as Jane. You know that Jane has 12 dollars more than Peter so you can think of scenarios. Because it is a 1/3 the answer for Peters money has to be 1/3 of Janes, so Peter has 6 dollars, and Jane has 12 more, so Jane has 18 dollars.

(2) Explain how the product of 3 and 65 could be used to find (0.03) - (0.65).*
Answer:
See Explanation
Step-by-step explanation:
Required
Explain how 3 * 65 could be used for (0.03) * (0.65)
0.03 is to 2 decimal places and 0.65 is also to 2 decimal places
In total, we have: [tex]2 + 2 = 4[/tex]
So, to get (0.03) * (0.65) from 3 * 65.
Simply calculate the product: 3 * 65
Then divide by 10 to the power of the sum of the decimal places i.e. 4
This is shown below
(0.03) * (0.65)
Express as fraction
[tex](0.03) * (0.65) = \frac{3}{100} * \frac{65}{100}[/tex]
[tex](0.03) * (0.65) = \frac{3*65}{100*100}[/tex]
[tex](0.03) * (0.65) = \frac{3*65}{10^2*10^2}[/tex]
[tex](0.03) * (0.65) = \frac{3*65}{10^4}[/tex]

What is the extraneous solution of the given absolute value equation?
-2|-2x-4|=-12
9514 1404 393
Answer:
is no extraneous solution
Step-by-step explanation:
An absolute value equation typically does not have extraneous solutions. The solutions to this one are ...
x ∈ {-5, 1}
__
Unless there is some domain restriction, this equation has no extraneous solutions.
_____
For -2x-4 < 0
-2(2x +4) = -12
x +2 = 3
x = 1 . . . . . . -2(1)-4 = -6 < 0. Not an extraneous solution

For -2x-4 > 0
-2(-2x -4) = -12
4x +8 = -12
4x = -20
x = -5 . . . . . . -2(-5) -4 = 6 > 0. Not an extraneous solution

What is the approximate volume of a sphere with a diameter of 20 feet? Use 3.14 for it.
Answer:
4,188.79 and when its rounded its 4,188.8
Step-by-step explanation:
Volume of a sphere with a diameter of 20 feet is 4189.33 cubic feet.
What is Three dimensional shape?Three dimensional shape can be defined as a solid figure or an object or shape that has three dimensions—length, width, and height.
Given,
sphere with a diameter of 20 feet
Diameter is two times of radius
Diameter=2Radius
Radius =Diameter/2
Radius = 20/2=10 feet.
Volume of sphere=4/3πr³
π=3.142
Volume of sphere=4/3(3.142)(10)³
=4/3×3.142×1000
=4189.33 cubic feet.
Hence, volume of a sphere with a diameter of 20 feet is 4189.33 cubic feet.

Write an expression that is the product of two factors and is equivalent to - 2x - 16.
Which expression is the product of two factors and is equivalent to - 2x - 16?
O A. -2x-1-15
OB. -2(x-8)
OC. (8x - 1)-(10x-15)
OD -2(X + 8)
Answer:
D
Step-by-step explanation:
Our answer will be D. We can eliminate choices A and C since they are not products. In other words, they are not multiplying factors together; they are only adding or subtracting.
Answer B does not work, as when it is multiplied out, we get -2x + 16.
When we find the product of D, we distribute the negative and get the correct product, -2x - 16

DeShawn and Mike each improved their yards by planting rose bushes and geraniums. They
bought their supplies from the same store. DeShawn spent $13 on 1 rose bush and 4 geraniums.
Mike spent $56 on 10 rose bushes and 3 geraniums. Find the cost of one rose bush and the cost of one geranium.
Answer:
Cost of 1 rose bush = x = $5
Cost of 1 geraniums = y = $2
Step-by-step explanation:
DeShawn and Mike each improved their yards by planting rose bushes and geraniums. They bought their supplies from the same store.
Let us represent:
Cost of 1 rose bush = x
Cost of 1 geraniums = y
DeShawn spent $13 on 1 rose bush and 4 geraniums.
x + 4y = 13..... Equation 1
x = 13 - 4y
Mike spent $56 on 10 rose bushes and 3 geraniums.
10x + 3y = 56....... Equation 2
We substitute 13 - 4y for x in Equation 2
10(13 - 4y) + 3y = 56
130 - 40y + 3y = 56
Collect like terms
- 40y + 3y = 56 - 130
-37y = -74
y = -74/37
y = $2
Solving for x
x = 13 - 4y
x = _13 - 4 × $2
x = $13 - $8
x = $5
Therefore,
Cost of 1 rose bush = x = $5
Cost of 1 geraniums = y = $2

Magdala is modeling 2.12÷4 how to cheeks change the place value blocks so she can make 4 equal shares
Answer and explanation:
If Magdala is trying to divide 2.12 by 4 then she would definitely need to change the place value of the dividend(2.12) and the divisor(4). In other words, both numbers need to be whole numbers.
To make 2.12 a whole number, we shift the decimal point two places to the right of the decimal point to get 212. We do same for 4 to get 400, since both numbers have to have their place values adjusted equally.
We divide 212 by 400 to get 0.53
Therefore 2.12 divided by 4= 0.53
