Answer:
The scale of dilation is 2.5
Step-by-step explanation:
K · ( 0, 0 ) = ( 0 , 0 )
k · ( 0 , 4 ) = ( 0 , 10 )
k · ( 6, 0 ) = ( 15, 0 )
k = 15/6 = 10/4 = 2.5
The scale of dilation is 2.5

What is Substitution method?
To find the value of any one of the variables from one equation in terms of the other variable is called the substitution method.
The expressions are;
1. 16
2. n - 2
3. 1/16
4. 1/n²
Now, Put n = 4 in all given expression we get;
The first expression is,
16
The second expression is,
n - 2
= 4 - 2
= 2
The third expression is,
1/16
The fourth expression is,

Answer:
13
Step-by-step explanation:
13x75000=975000
Check for reasonableness...
975000/75000=13
So the answer is 13 gallons.
P.S. There will still be 25,000 drops left, which is 1/3 of a gallon.

Step-by-step explanation:
-3(3x+8)+2=26-3x
We move all terms to the left:
-3(3x+8)+2-(26-3x)=0
We add all the numbers together, and all the variables
-3(3x+8)-(-3x+26)+2=0
We multiply parentheses
-9x-(-3x+26)-24+2=0
We get rid of parentheses
-9x+3x-26-24+2=0
We add all the numbers together, and all the variables
-6x-48=0
We move all terms containing x to the left, all other terms to the right

Another way to identify the domain and range of functions is by using graphs. Because the domain refers to the set of possible input values, the domain of a graph consists of all the input values shown on the x-axis. The range is the set of possible output values, which are shown on the y-axis.

What is 3x + 2 + 4x - 1 after combining like terms
Answer:
7x+1
Step-by-step explanation:
When you look at the expression(3x+2+4x-1), you will notice that some have variables while some are just regular numbers.
First, focus on the variables. 3x and +4x. In the expression, you will have to add it so 3x+4x will be 7x. Now, keep 7x on the side and switch to the numbers.
Next, focus on the numbers. 2 and -1. All you have to do is combine them which will be 2-1 which also equals 1.
Finally, return 7x with 1 which will be 7x+1. The reason you add a + sign instead of a - sign is because you got positive 1, not negative 1.
Your answer is 7x+1.
A small town’s raffle has 85 entries and 3 gift baskets that three different people could win. What is the probability of winning a gift basket if you have 1 of the entries
Answer:
[tex]\dfrac{3}{85}[/tex]
Step-by-step explanation:
It is given that a small town’s raffle has 85 entries and 3 gift baskets that three different people could win.
Total number of entries = 85
Total number of gift baskets = 3
We need to find the probability of winning a gift basket.
[tex]\text{Required probability}=\dfrac{\text{Total number of gift baskets}}{\text{Total number of entries}}[/tex]
[tex]\text{required probability}=\dfrac{3}{85}[/tex]
Therefore, the required probability is [tex]\dfrac{3}{85}[/tex].
In the figure shown, AB = 8 and AD = 5. What is BC?
Answer: 5
Step-by-step explanation:
Since we know that equal number of dashes will always be equal to another we can easily solve the question. They said AB=8 and as you can see 8 is represented by two dashes here and if we take in what i said earlier,, that means DC= 8 too. They also said AD= 5. Since 5 is represented by one dash we can easily see that since BC also has one dash,, it is going to be equal to AD which concluded to the answer of 5.

Rewrite the equation for x, and express its value in terms of a. 3/a x - 4 = 20
For this case, we must clear variable "x" from the given equation, expressed in terms of "a".
We have:
3/a x-4=20
By clearing "x" we have:
Adding 4 to both sides of the equation:
3/a x = 20 + 4
Multiplying by a/3 on both sides of the equation:
x=24a/3
x=8a
So, x=8a
Answer:
x=8a
— 7 + 4p = -8p + 11
just the answer
or steps if you can
Answer:
p = 1.5
Step-by-step explanation:
— 7 + 4p = -8p + 11
Add 8p to each side
— 7 + 4p+8p = -8p+8p + 11
-7 +12p = 11
Add 7 to each side
-7+7 +12p = 17
12p = 18
Divide each side by 12
12p/12 =18/12
p = 18/12
p = 3/2

A field in the shape of a trapezoid has an area of 13.687.5 square yards the length of one base is 150 yards and the length of the other base is 215 yards what is the height of the trapezoid
This question is not correctly written
Complete Question
A field in the shape of a trapezoid has an area of 13,687.5 square yards the length of one base is 150 yards and the length of the other base is 215 yards what is the height of the trapezoid
Answer:
The height of the trapezoid is 75 yards
Step-by-step explanation:
Area of a Trapezoid = 1/2(b1 + b2) × h
Where b1 = Length of the first base
b2 = Length of the second base
h = height of the trapezoid
From the question
Area of the trapezoid = 13,687.5 yd²
b1 = Length of the first base = 150 yards
b2 = Length of the second base = 215 yards
h = height of the trapezoid
Hence, we have
13,687.5 = 1/2(150 + 215)h
13,687.5 = 365h/2
13,687.5 × 2 = 365h
h = 13687.5 × 2/365
h = 75 yards
Therefore, the height of the trapezoid is 75 yards.
What are the coordinates of Y if the midpoint of line segment XY is (2,-5) and the coordinates of point X is (4,4)?
Answer:
Y(0, - 14 )
Step-by-step explanation:
Given endpoints (x₁, y₁ ) and (x₂, y₂ ) then the midpoint is
[ [tex]\frac{1}{2}[/tex] (x₁ + x₂ ), [tex]\frac{1}{2}[/tex] (y₁ + y₂ ) ]
Use the midpoint formula and equate corresponding parts to the coordinates of the given midpoint
let Y = (x, y ), then
[tex]\frac{1}{2}[/tex] (4 + x) = 2 ( multiply both sides by 2 )
4 + x = 4 ( subtract 4 from both sides )
x = 0
and
[tex]\frac{1}{2}[/tex] (4 + y ) = - 5 ( multiply both sides by 2 )
4 + y = - 10 ( subtract 4 from both sides )
y = - 14
Thus
coordinates of Y = (0, - 14 )
J is between H & K, if HJ=4t-15, JK=5t-6, and KH=15, find JK
Answer:
JK = 39
Step-by-step explanation:
HJ and JK are segments of line segment HK, so they must add up to the length of KH.
HJ + JK = HK
By substituting in the values of each line segment, we can solve for t.
(4t - 15) + (5t - 6) = 15
9t - 21 = 15
9t = 36
t = 9
Now that we have t, we can plug it in in order to find the value of JK.
JK = 5t - 6
5(9) - 6
45 - 6
39
JK = 39

3/7 rounded to the nearest hundredth
Answer:
0.4285714286.
The hundredth place is 2 places to the right of the decimal. In this case, it is 2. So we look to the number to the right of 2 (which is 8). 8 ≥ 5, so the 2 gets rounded to a 3.
0.43
Answer:
The answer is 0.43
Step-by-step explanation:
When you divide 3 by 7, you get 0.42857142857142857142857142857143.
To round to the nearest hundredth, you go 2 numbers after the decimal place. The number on the right of the 2nd number (which is in the hundredths place) will either make the number round up or down. Since the number 8 is greater than 5, the number rounds up.
So, the answer will be 0.43
