Cara has driven one-fifth of the total distance, d, to her destination.
Which statement explains why both 1/5d and 0.2d can find the distance she has driven?
Multiplying by 1/5 is the same as multiplying by 20%.
Multiplying by 1/5 is the same as multiplying by 2%.
The fraction 1/5 is the same as the decimal 0.8. Therefore, 1/5d can be written as 0.8d.
The expressions are not equivalent.

The net of a rectangular prism is shown below. What is the total surface area of the rectangular prism represented by this net?
Answer:
150.88 cm²
Step-by-step explanation:
A rectangular prism also known as cuboid is a three dimensional object with six rectangular faces and eight vertices. It is a prism because it has the same cross section along the length. It is called a rectangular prism because its cross section is rectangular.
The opposite faces of a rectangular prism are equal to each other.
The total surface area (TSA) of a rectangular prism is:
TSA = 2(wl + wh + lh)
where w is the width of the base, l is the length of the base and h is the height of the prism.
From the question, we can see that:
w = 5 cm, l = 7.4 cm and h = 3.1 cm. therefore:
TSA = 2(wl + wh + lh) = 2[(5 * 7.4) + (5 * 3.1) + (7.4 * 3.1)] = 2(37 + 15.5 + 22.94)
TSA = 2(75.44)
TSA = 150.88 cm²

Answer: yes Jim is correct
Each side of the quadrilateral is congruent. Then the quadrilateral is known as the rhombus.
What is a quadrilateral?The quadrilateral has four sides and four angles. The sum of internal angles is 360 degrees.
If all the sides of the quadrilateral are congruent then the quadrilateral may be a square or rhombus.
If none of the angles of that quadrilateral is equal to 90 degrees. Then the quadrilateral is known as a rhombus.

What is Unit Conversion?The same attribute is expressed using a unit conversion, but in a different unit of measurement. For instance, time can be expressed in minutes rather than hours, and distance can be expressed in kilometres, feet, or any other measurement unit instead of miles.
Given:
1 Cups = 0.0625 Galloon.
Peter make 48 cups of drink.
So, 48 C/ 1 x 1 pt / 2C x 1 qt / 2 pt x 1 gal / 4 qt
= 24 pt x 1 qt / 2 pt x 1 gal / 4 qt
= 3 gal
Hence, 48 cups of the drink.

The function G(t) = 2t represents the number of guitar lessons, G(t) you can complete in T months. How many guitar lessons can you complete in seven months
Answer:
14 lessons can be completed
Step-by-step explanation:
From the question, to get the number of lessons that can be completed, we simply multiply the number of months by 2
Thus, we have that;
G(2) = 2 * 7
G(2) = 14 lessons

−10ba+15ba^2
−5b+2a−3a^2
10ba−15ba^2
Answer:
−10ba+15ba^2
Step-by-step explanation:
The product of the given monomial and binomial is -10ab+15a²b.
The given expression is −5b(2a−3a²).
We need to simplify the polynomial using multiplication.
What is an expression?An expression is a combination of terms that are combined by using mathematical operations such as subtraction, addition, multiplication, and division.
Binomials are also a kind of polynomials consisting of only two terms. A binomial is defined as an algebraic expression consisting of two terms that are separated by the arithmetic signs, either the addition sign (+) or the subtraction sign (-). When multiplying a monomial by a binomial, we follow the distributive law of multiplication.
Now, 2a×(−5b)−3a²×(−5b)
=-10ab+15a²b
Therefore, the product of the given monomial and binomial is -10ab+15a²b.

Find the solution of the system of equations. 9x +y = 28 3x + 3y = -12
Answer:
x is equal to four, and y is equal to negative eight.
Step-by-step explanation:
Let's solve it rearranging the first equation to define y:
9x + y = 28
y = 28 - 9x
Now we plug it in to the second equation:
3x + 3y = -12
3x + 3(28 - 9x) = -12
And solve for x:
3x + 84 - 27x = -12
-24x = -96
x = 4
Now we can plug that x value into one of the original equations to find the value of y
9x + y = 28
36 + y = 28
y = 28 - 36
y = -8
Let's test our answer by plugging that y value into the other equation, and seeing if we get the same x value:
3x + 3y = -12
3x + 3(-8) = -12
3x - 24 = -12
x - 8 = -4
x = 4
So we know our answer is correct.
Determine the solution to the system of equations:
y = 3x +4
y = 2x + 1

Deborah bought a computer for 25% off the list price. If the list price is $2,428, how much did Deborah spend? A. $607 B. $1,821 C. $2,115 D. $2,403
Answer:
Option A, [tex]\$607[/tex]
Step-by-step explanation:
Given: Deborah bought a computer for [tex]25\%[/tex] off the list price.
The list price is [tex]\$2,428[/tex].
To find: The amount Deborah spent on the computer.
Solution: We have,
List price of the computer [tex]=\$2,428[/tex].
Deborah bought the computer for [tex]25\%[/tex] off the list price.
The amount Deborah spent on the computer [tex]=25\% \times 2,428[/tex]
[tex]=\frac{25}{100}\times2428=\frac{2428}{4} =\$ 607[/tex].
So, Deborah spent [tex]\$607[/tex] on the computer.
Hence, option A is correct.
is this right? Whats the answer to C?
Answer:
a. Multiplication property of equality
b. Distributive property
c. addition property of equality
Step-by-step explanation:
The first one is wrong because you are multiplying the 2 on both sides to make it equal. There was nothing that they substituted for.
The second one will be the distributive property not the subtraction property of equality. They distributed the 2 into the [tex]\frac{1}{2}x[/tex] and the [tex]-5[/tex]. So that clears up that this step was the distributive property.
This one will be the addition property of equality because when you have a negative number you do the inverse so they added the 10 on both sides. Therefore it's the addition property of equality.
