triangle abc has the coordinates in the table below. Where will the location of A' be after a dilation using a scale factor of 1.25
Answer:
B i am pretty sure
Step-by-step explanation:
The location of A' be after a dilation using a scale factor of 1.25 is (-15 , -10) .
What is scale factor?Scale factor is defined as the number or the conversion factor which is used to change the size of a figure without changing its shape. It is used to increase or decrease the size of an object.
According to the question
ΔABC has the coordinates
A(-12,-8)
B(-16,-4)
C(-4,-8)
Now,
The location of A' be after a dilation using a scale factor of 1.25
i.e
A' = (Ax* 1.25 , Ay*1.25 )
A' = (-12* 1.25 , -8*1.25 )
A' = (-15 , -10)
Hence, the location of A' be after a dilation using a scale factor of 1.25 is (-15 , -10) .

Please explain your answer.
Answer:
The Answer here is 11
Step-by-step explanation:
First, we divide inside the parentheses because we always do what is inside the parentheses first, and division comes before addition. So 12/4 is 3. Next we add 3 plus 1, which is 4. Then we multiply (Because multiplication comes before subtraction, and parentheses mean multiplication) 4 times 1 which is 4. Then we subtract 15-4 which comes out to 11.
Hence the answer here is 11.

Answer:
a) 4 quarts of sparkling water
b) 38.5 quarts of grape juice
c) 80 quarts of sparkling water and 20 quarts of grape juice
The answers for the letters in the chart are on the bottom for b and c.
Step-by-step explanation:
a) You would need 4 quarts of sparkling water for 1 quart of grape juice.
This proportion is to get the amount of grape juice you need you multiply the amount of sparkling water by .25 to get the amount of grape juice you need.
So for a) I know that .25 of a quart of grape juice is equal to 1 quart of sparkling water. So to get the amount of sparkling water multiply the amount of grape juice you need by .25. And the number you multiplied .25 will be the amount of sparkling water you need. Example: 4 × .25 = 1 quart of grape juice.
4 is the amount of sparkling water you need.
b) For b you just need to multiply the amount of sparkling water by .25 to get the amount of grape juice you need.
154 × .25 = 38.5
You need 38.5 quarts of grape juice.
c) You would need 80 quarts of sparkling water and 20 quarts of grape juice.
80 × .25 = 20
b on the graph is 38.5 because 154 × .25 = 38.5
c on the graph is 400 because .25 × 400 = 100

-The submarine started at 275 feet below sea level
-After one hour, the submarine is 325.8 feet below sea level. How many feet did it dive?
-After two hours, the submarine dives another 23 feet deeper.
-On hour three, the submarine descended the average of dives from hour one and two.
-Fill in chart below using the information above. Sea level is considered 0 feet.
Answer:
Step-by-step explanation:
1. if the sub is at 325.8 at it was originally at 275 you have to put the numbers in absolute value. so 325.8 - 275=50.8
the sub went down -50.8 feet to get to 325.8
if the diver dives another 23 feet you have to put the numbers in absolute value and add 325.8 + 23= -348.8 feet underwater
on hour 3 it says that it descends an average of how much he went down in the first 2 hours witch is -73.8
i got -73.8 by adding hours one and two
then you add hour 3 by -348.8

Mr. Santos treated his students to a movie for winning the state contest. This also required taking some of the students’ parents as chaperones. The movie theatre charges $4 for each student and $6 for each adult. If Mr. Santos spent $180 on movie tickets and took 40 people (including himself), how many students did he take to the movies.
write two equations to help find the answer
Answer: 41
Step-by-step explanation:
Using a system of equations, it is found that he took 30 students to the movies.
------------------------------
This question is solved using a system of equations, and I will say that:
x is the number of students taken.y is the number of adults taken.------------------------------
40 people were taken, and thus:
[tex]x + y = 40[/tex]
As we want the number of students x, we can represent y as function of x, thus:
[tex]y = 40 - x[/tex]
------------------------------
Each student costs $4.Each adult costs $6.The total amount spent was $180.Thus:
[tex]4x + 6y = 180[/tex]
Since [tex]y = 40 - x[/tex]
[tex]4x + 6(40 - x) = 180[/tex]
[tex]4x + 240 - 6x = 180[/tex]
[tex]-2x = -60[/tex]
[tex]2x = 60[/tex]
[tex]x = \frac{60}{2}[/tex]
[tex]x = 30[/tex]
He took 30 students to the movies.

Ms. Romero runs a house cleaning business. To save money, she bought a 1-gallon container of concentrated cleaner. She mixed the cleaner with 10 gallons of water. Then, she filled as many 1-pint spray bottles as she could. How many spray bottles did she fill?
Answer:
88
Step-by-step explanation:
The number of 1-pint spray bottles she can fill with 11 gallons is 88.
What is unit conversion?It is the conversion of one unit to another unit with its standard conversion.
Example:
1 km = 1000 m
1 hour = 60 minutes
We have,
The quantity of cleaner and water mixed.
= 1 gallon + 10 gallons
= 11 gallons
Now,
1 gallon = 8 pint
Multiply 11 on both sides.
11 gallon = 88 pints
Thus,
The number of 1-pint spray bottles is 88.

Answer:
slope= 3/4
y=mx+b
Step-by-step explanation:
Answer:
3/4
Step-by-step explanation:
The rate of change is referring to the slope, which can be calculated by rise/run. There are two points we can use to find the slope: (0,3) an (4,6), but feel free to use any points on the graph that you want to. Between those two points, the function's y value ("rise") increases by 3, while the function's x-value ("run") increases by 4. Divide 3 (rise) by 4 (run) in order to calculate the rate of change.

Solve the equation.
2.5 = 0 - (-20)
0-17.5
0-22.5
O 22.5
0 17.5
Answer:
Step-by-step explanation:Simplifying
0 = 2.5y + -20
Reorder the terms:
0 = -20 + 2.5y
Solving
0 = -20 + 2.5y
Solving for variable 'y'.
Move all terms containing y to the left, all other terms to the right.
Add '-2.5y' to each side of the equation.
0 + -2.5y = -20 + 2.5y + -2.5y
Remove the zero:
-2.5y = -20 + 2.5y + -2.5y
Combine like terms: 2.5y + -2.5y = 0.0
-2.5y = -20 + 0.0
-2.5y = -20
Divide each side by '-2.5'.
y = 8
Simplifying
y = 8
SO the answer is y=8 I think srry if i get it wrong
Does the size of a circular object affect the relationship between its circumference and its diameter?
A. The size will affect the relationship between circumference and diameter because of circumference changes at a greater rate than the diameter.
B. The size has no effect on the relationship between circumference and diameter because the ratio is always equal to
C. The size has no effect on the relationship between circumference and diameter because the two values change independently.
D. The size will affect the relationship between circumference and diameter because of the value changes as the circumference changes.
Answer: A
Step-by-step explanation: It doesn't. The circumference of a circle is 2*pi*radius and the diameter is 2*radius, so the circumference divided by the diameter is pi, which is the ratio of circumference to diameter.
