20 of the 80 coffee mugs at Carson's Pancake House are dirty. What percentage of the coffee mugs at the pancake house are dirty?
Answer:
25%
Step-by-step explanation:
20/80 in can be reduced to 1/4 and 1/4 equals 25%.
We have:
[tex]\dfrac{20}{80} = \dfrac{\%} {100}[/tex]
Solving for %:
[tex]\% = \dfrac{20\cdot 100}{80} = 25\%[/tex]
R/ 25% of coffee mugs are dirty.

Answer:
150 and -150
Step-by-step explanation:
For question number 2...
You started off with an energy level of 250 and something was added to make it 400.
To figure out what this "something" was, you simply subtract the numbers.
400 - 250 = 150
For question number 3...
You start off with 325 and end with 175. Here, the outcome is smaller or less than what you started with. So, you know that you took away a certain amount of energy. To figure that out, you again subtract.
325 - 175 = 150
To make the equation make sense, you would subtract 150.
So the answer would -150.
Simplify ( 5^2x7^4 ) 10
Answer:
5^20 • 7^40
Step-by-step explanation:
each exponent needs to multiply each 10.
Answer:
D. [tex]5^{20}[/tex] x [tex]7^{40}[/tex]
Step-by-step explanation:
Original Equation= [tex](5^2 \cdot 7^4)^{10}[/tex]
Apply exponent rule: [tex](a\cdot b) ^n[/tex] = [tex]a^n[/tex] [tex]b^n[/tex]
= [tex](5^2)^{10}[/tex] x [tex](7^4)^{10}[/tex]
Distribute them
= [tex]5^{20}[/tex] x [tex](7^4)^{10}[/tex]
= [tex]5^{20}[/tex] x [tex]7^{40}[/tex]

Point G and point H are the same distance form point F. Which coordinates could be the location of point H?
Note: It seems, you missed to add the correct option. But, I am solving the question to clear your concept anways.
Answer:
The coordinates of H are:
(x₂, y₂) = (2, 0)Step-by-step explanation:
Given the points
F(3, 2)G(4, 4)Since Point G and point H are the same distance from point F, therefore the point F is the mid-point of G and H
using the mid-point formula
[tex]m\:=\:\left(\frac{x_2+x_1}{2},\:\:\frac{y_2+y_1}{2}\right)[/tex]
Since the point F is the mid-point of G and H, so
m = (3, 2)
as
(x₁, y₁) = (4, 4) = G (x₂, y₂) = H = ?Thus, substituting m = (3, 2), (x₁, y₁) = (4, 4) to determine coordinates of the point H (x₂, y₂)
[tex]m\:=\:\left(\frac{x_2+x_1}{2},\:\:\frac{y_2+y_1}{2}\right)[/tex]
[tex]\left(3,\:2\right)\:=\:\left(\frac{x_2+4}{2},\:\:\frac{y_2+4}{2}\right)[/tex]
so
[tex]\:\:3\:=\:\frac{x_2+4}{2}[/tex]
[tex]x_2+4=6[/tex]
subtract 4 from both sides
[tex]x_2+4-4=6-4[/tex]
[tex]x_2=2[/tex]
and
[tex]2=\:\frac{y_2+4}{2}[/tex]
[tex]\:y_2+4\:=\:4[/tex]
subtract 4 from both sides
[tex]y_2=0[/tex]
Thus, the coordinates of H are:
(x₂, y₂) = (2, 0)Note: It seems, you missed to add the correct option.

Answer:
L = 25
Step-by-step explanation:
Let's call the Length x and width x - 15 since the width is 15 less than length
Eric needs 70 of fencing in total, the perimeter of a rectangle is calculated by adding all sides
x + x + (x - 15) + (x - 15) = 70 add like terms
4x - 30 = 70 add 30 to both sides
4x = 100 divide both sides by 4
x = 25
Answer :
Given :
The shape of the yard is rectangularWidth is 15 yards less than the lengthTotal fencing required is 70 feetTo find :
Appropriate equation DimensionsSolution :
We know that for fencing we need to find the perimeter ,
Perimeter of a rectangle => 2 ( length + breadth )Let us assume the value of length be x yards
Width = x - 15 yardsSolving the question we get ,
2 ( x + ( x - 15 ) ) = 702 ( x + x - 15 ) = 702 ( 2x - 15 ) = 704x - 30 = 704x = 100[tex]\sf\implies\:x\:=\:\dfrac{100}{4}[/tex]x = 25Length = 25 yards

a recipe uses 1 1/4 cups of milk to make 10 servings. if the same amount of milk is used for each serving, how many servings can be made using 1 gallon of milk? take 1 gallon to be equal to 16 cups. please show the work!
Answer:
128 servings can be made using 1 gallon of milk.
Step-by-step explanation:
Given that:
[tex]1\frac{1}{4}[/tex] cups of milk make 10 servings
[tex]1\frac{1}{4}[/tex] can also be written as 1.25
Ratio of cups of milk to servings = 1.25 : 10
1 gallon = 16 cups
Let,
x be the number of servings made from 1 gallon
Ratio of cups of milk to servings = 16 : x
This is a direct proportion
1.25 : 10 :: 16 : x
Product of mean = Product of extreme
10*16 = 1.25x
160 = 1.25x
1.25x=160
Dividing both sides by 1.25
[tex]\frac{1.25x}{1.25}=\frac{160}{1.25}\\x=128[/tex]
Hence,
128 servings can be made using 1 gallon of milk.

Rectangle LMNP was dilated using the rule DP,3. Which statements are true? Check all that apply. The length of line segment M'N' is 18 units. The length of segment M'N' is 14 units. The dilation is a reduction. The dilation is an enlargement. The scale factor is One-third. The scale factor is 3.
The given rule of the dilation indicates that the scale factor is 3 which is
larger than one, therefore, given an enlarged image.
The correct options are;
The length of line segment M'N' is 18 unitsThe dilation is an enlargementThe scale factor is 3Methods by which the scale factor is obtainedPlease find attached the possible diagram of rectangle LMNP obtained from a similar question posted online;
L'M' = 12
LM = 4
MN = 6
The rule of the dilation of rectangle LMNP = [tex]D_{p, \, 3}[/tex]
L'M' = 3 × LM
Therefore;
The image following the dilation of the preimage LMNP, which is rectangle L'M'N'P' is larger than LMNP
Therefore;
The dilation is an enlargementThe scale factor is the number with which the preimage dimension is multiplied to get the image, which is 3
The scale factor is 3M'N' = 3 × MN
Therefore;
The length of line segment M'N' = 3 × 6 units = 18 unitsLearn more about scale factor of a dilation here:

What is the nature of roots of x- 9x = 20 ?
a. nonreal
b. real, rational, and equal
c. real, rational, and unequal
d. real, irrational, and unequal
Answer:
Option C
Step-by-step explanation:
To find the nature of the roots we use the Discriminant formula which is:
[tex]D=b^2-4ac[/tex]
and given the equation and compare with the standard quadratic equation
[tex]x^2-9x=20\\x^2-9x-20=0\\ax^2+bx+c=0[/tex]
Here our a is 1 , b is -9 and c is -20 so we plug a, b, c into the Discriminant formula
[tex]D=b^2-4ac\\D=(-9)^2-4(1)(-20)\\D=81+80\\D=161[/tex]
Since D > 0 (greater than zero) our roots are real and unequal for the rational and irrational part we got know the the Discriminant's square root value if it is in decimals the nature of the roots are irrational if the Discriminant's value is a whole number then it is rational and so 161 has a square roots in points which is
[tex]D=\sqrt{161} \\D=12.6885[/tex]
So our answer is real , irrational and unequal which is Option C

A line passes through the point (-4, 7) and has a slope of -5/4
Write an equation in slope-intercept form for this line.
Answer:
We conclude that the equation in slope-intercept form for this line will be:
[tex]y\:=\:\frac{-5}{4}x+2[/tex]
Step-by-step explanation:
Given
The point = (-4, 7)slope = m = -5/4We know that the slope-intercept form of the line equation is
[tex]y=mx+b[/tex]
where m is the slope and b is the y-intercept
Using the slope-intercept form to find the y-intercept 'b'
substituting m = -5/4 and the point (-4, 7)
[tex]y = mx+b[/tex]
[tex]7=\:\frac{-5}{4}\left(-4\right)+b[/tex]
[tex]-\left(-5\right)+b=7[/tex]
[tex]5+b=7[/tex]
subtract 5 from both sides
[tex]5+b-5=7-5[/tex]
[tex]b=2[/tex]
now substituting b = 2 and m = -5/4 in the slope-intercept form
[tex]y = mx+b[/tex]
[tex]y\:=\:\frac{-5}{4}x+2[/tex]
Therefore, we conclude that the equation in slope-intercept form for this line will be:
[tex]y\:=\:\frac{-5}{4}x+2[/tex]
