PLS HELP NEED ASAP The formula d=rt gives the distance traveled for a rate r and an amount of time t. A car travels at a rate of 60 miles per hour for 3 hours. What distance did the car travel? 20 miles 57 miles 63 miles 180 miles
Distance = rate x time
Distance = 60 x 3
Distance = 180 miles.
Answer:
180m
Step-by-step explanation:
d= distance traveled => ?m
r= rate => 60m/h
t= time => 3h
Formula=> d=r.t
>d= 60 x 3=> d= 180m
So
d= distance traveled => 180m
r= rate => 60m/h
t= time => 3h
Find the slope given the following points: (12,-2) and (4,-6)
The slope of the point (12,-2) and (4,-6) is; 1/2
What is the Point-slope form?The equation of the straight line has its slope and given point.
If we have a non-vertical line that passes through any point(x1, y1) and has a gradient m. then general point (x, y) must satisfy the equation;
y-y₁ = m(x-x₁)
we have been given two points (12,-2) and (4,-6).
Then the slope is;
m = (-6 - (-2))/ (4 - 12)
m = -4 / -8
m = 1/2
The equation of line is y + 2 = 1/2(x - 12)
Hence, the slope of the point (12,-2) and (4,-6) is 1/2.

If the domain of a function that is translated up 5 is (-1,8), (-2,4),(-1, -7),
what is the range?
O (-1,3), (-2,-1),(-1,-12)
O (-6,8).(-7,4), (-6, -7)
O (5,8), (3,4),(4,-7)
0 (-1, 13), (-2,9),(-1,-2)
Answer:
The right answer is 0 (-1, 13), (-2,9),(-1,-2).
Step-by-step explanation:
if (-1,8), (-2,4),(-1, -7) has already translated the domain, then all you need to do is add 5 to every range in the relation. To which will become (-1, 13), (-2,9),(-1,-2) .

Answer:
x = - 5
Step-by-step explanation:
Given
[tex]\frac{2x-20}{3}[/tex] = 2x ( multiply both sides by 3 to clear the fraction )
2x - 20 = 6x ( subtract 2x from both sides )
- 20 = 4x ( divide both sides by 4 )
- 5 = x , that is x = - 5
A gold earring has a volume of 0.55cubic centimeters and a mass of 9.9grams. Calculate its density.
Answer:
.018 Kg/cm^3
Step-by-step explanation:
[tex]p = m \div v \\ [/tex]
Density (P) is equal to the mass (9.9g) divided by volume (.55cm^3)
[tex] = 9.9 \div .55[/tex]
= 18g/cm^3
=.018kg/cm^3
The density with given mass and volume is 18 g/cm³.
What is density?Density is the measurement of how tightly a material is packed together. It is defined as the mass per unit volume.
Given that, a gold earring has a volume of 0.55 cubic centimeters and a mass of 9.9 grams.
We know that, density =Mass/Volume
Density = 9.9/0.55
= 18 g/cm³
Therefore, the density with given mass and volume is 18 g/cm³.

Explain how to find 7/10 + 9/10
Answer:
8/5 is the answer
Step-by-step explanation:
7/10+9/10
7+9/10( because if the lcm is same in both the expression we can write one of them and do according to the sign)
16/10( adding the number)
8/5( dividing the numbers and finding the value in fraction form)
OR,
16/10

8x - 3 = 3x + 2
A. One solution
B. Infinite solutions
C. No solutions
please explain how you got it
A one solution because it's x=1
Step By Step explanation:this is the original problem
8x-3=3x+2
we want to have x by itself so. . .
we add three on both sides. it cancels -3. And 2+3=5
8x=3x+5
we subtract 3x on both sides so 8x-3x=5x and 3x cancels on the other side
5x=5
we divide by 5 on both sides to get x by itself
x=1
if it was 1=1 or x=x (the same on both side) it would've been infinite solutions. if the numbers didn't match like 4=6 it would've been no solution

Answer: 4 3/8 ≈ 4.38
Step-by-step explanation:
To start off, note that 4 3/8 is a mixed number, also known as a mixed fraction. It has a whole number and a fractional number. We have labeled the parts of the mixed number below so it is easier to follow along.
4 = Whole number
3 = Numerator
8 = Denominator
To get 4 3/8 in decimal form, we basically convert the mixed number to a fraction and then we divide the numerator of the fraction by the denominator of the fraction.Step 1: Multiply the whole number by the denominator:
4 × 8 = 32
Step 2: Add the product you got in Step 1 to the numerator:
32 + 3 = 35
Step 3: Divide the sum from Step 2 by the denominator:
35 ÷ 8 = 4.375
That's it folks! The answer to 4 3/8 in decimal form is displayed below:
4 3/8 ≈ 4.38

I Which of the following is the most appropriate unit to describe the rate at which people are entering Disneyland?
A People per hour, because the dependent quantity is the people
B Hours per person, because the dependent quantity is the hours
C Hours per person, because the dependent quantity is the people
D People per hour, because the dependent quantity is the hours
Answer: D
Step-by-step explanation:
Answer:
d) People per hour, because the dependent quantity is the people
Step-by-step explanation:
In this situation, the two quantities are people and hours. These are the two things in this problem we can count or measure.
The independent variable is the one that causes a change, while the dependent variable is the one that gets changed. In this situation, the number of people change every hour; this means the number of people gets changed, which makes it the dependent variable. This means that the independent variable must be time.
Since people is dependent and time is independent, "people per hour" would be the best form of this statement.

3.) \$0.78$0.78dollar sign, 0, point, 78 tip for a \$5.20$5.20dollar sign, 5, point, 20 order
Answers
1) proportional to Mike's tip
2) Not proportional to Mike's tip
3) proportional to Mike's tip
Step-by-step explanation:
when two things have the same relative sides, they are said to be proportional.
To determine if the other tips are proportional to Mikel's tip, we will, first of all, determine the size of Mikel's tip, then compare the other tips with it.
Mikel's tip:
$1.32 for $8.80
= [tex]\frac{1.32}{8.80}= 0.15[/tex]
Now, let us compare this with the other tips
1.) $2.22 for 14.80
= [tex]\frac{2.22}{14.80} = 0.15[/tex]
proportional to Mike's tip
2.) $1.86 for $10.50
[tex]\frac{1.86}{10.50} = 0.177\\0.177 \neq 0.15[/tex]
Not proportional to Mike's tip
3.) $0.78 for $5.20
= [tex]\frac{0.78}{5.20} = 0.15[/tex]
proportional to Mike's tip

what is the greatest common factor of 8 and 16
Answer: 8
Step-by-step explanation: Usually you should use prime factorization or the “ladder” method; however, with questions like this that have small, easy numbers, you can simply think about it. Every number’s largest factor is itself, which means that 8 is at least a factor of 8. We also know that 8 times 2 equals 16, hence, the greatest common factor is 8.
10. The surface area of a cylinder with radius rand height h is twice the product of r and the
square of the radius plus twice the product of it, the radius, and the height.
Education
Financial Algebra, F
11
Step-by-step explanation:
The cylinder is a closed figure which consists of two circular ends. If r is the radius and h is the height of the cylinder, then its surface area is given by :
[tex]A=2\pi rh[/tex]
or
[tex]A=2\pi \times r\times h[/tex]
We also know that, surface area = perimeter×height
So, the surface area of the cylinder is the product of circumference of the circle and height of the cylinder.
