Answer:
The answer is C, y = 1/4x - 4
Step-by-step explanation:
First, we have to find the slope of the perpendicular line, and to do so you must take the slope of the given line and opposite reciprocate it.
To do so, you first reciprocate the slope by flipping the numerator and denominator which now makes -4 into -1/4.
Then we have to make it the opposite value, like making a negative into a positive or a positive into a negative. In this case you make -1/4 into a positive 1/4.
We now have the slope of the perpendicular line and can make out answer choices A and B. Which now leaves us with C and D.
The line must go through the point (4, -3). To do that we must adjust the y-intercept until it goes though that point.
We get the y-intercept of -4 and the line that has the y-intercept of -4 and the slope of 1/4 is C.
You answer is C, y = 1/4x - 4.

Answer:
x = 21
Step-by-step explanation:
The angle T is an exterior angle to the ∆RST, so will be equal to the sum of the remote interior angles:
T = 4x° +2x° = 6x°
T is also a same-side exterior angle with the one marked 54°, so is supplementary to that:
T + 54° = 180°
6x° + 54° = 180°
x + 9 = 30 . . . . . . . . divide by 6
x = 21 . . . . . . . . . . . . subtract 9
_____
Check
The triangle angles are ...
4x = 84°
2x = 42°
unmarked = 54°
Their sum is 84° +42° +54° = 180° . . . as it should be.
If P=2L+2W, solve for W.
Answer:
W = (P-2L)/2
Step-by-step explanation:
Isolate W
P = 2L + 2W
subtract 2L from each side
P - 2L = 2W
divide each side by 2
(P-2L)/2 = W

It takes you 7 minutes to do 2 math problems. How long will it take you to do one of Mr. Bruno’s homework assignments with 27 questions?
Answer:
94.5 minutes or 1 hour and 34.5 minutes
Step-by-step explanation: If it takes you 7 minutes for 2 math problems then that means it takes you 3.5 minutes for one problem. Then you multiply it by 27 and you get 94.5 minutes you can convert it into 1 hour and 34.5 minutes if you want.
To make 5 gallons of cleaning solution, 3 cups of bleach is mixed in with water.
Which table shows the relationship between the gallons of cleaning solution made and the cups of bleach used?
Answer:
Option B.
Step-by-step explanation:
Let 'g' represent the number of gallons of cleaning solutions.
Let 'c' represent the number of cups of bleach.
From the question given above, we were told that:
To make 5 gallons of cleaning solution, 3 cups of bleach is mixed in with water.
This implies that number of gallons (g) of the cleaning solution is directly proportional to the number of cups (c) of the bleach mixed with water i.e
g ∝ c
g = Kc
K is the constant of proportionality.
Next, we shall determine the relationship between g and c as follow
g = 5
c = 3
K =?
g = Kc
5 = K × 3
Divide both side by 3
K = 5/3
g = Kc
K = 5/3
g = 5/3 c
Thus, the relationship between g and c is:
g = 5c / 3
Next, we shall make c the subject of the formula. This is illustrated below:
g = 5c / 3
Cross multiply
3g = 5c
Divide both side by c
c = 3g/5
Next, we shall determine c when g = 10, 15, and 20.
This is illustrated below:
g = 10
c =?
c = 3g/5
c = (3 × 10)/5 = 30/5 = 6
g = 15
c =?
c = 3g/5
c = (3 × 15)/5 = 45/5 = 9
g = 20
c =?
c = 3g/5
c = (3 × 20)/5 = 60/5 = 12
Summary:
Num. of gallon (g) >> Num. of cup (c)
5 >>>>>>>>>>>>>>>> 3
10 >>>>>>>>>>>>>>> 6
15 >>>>>>>>>>>>>>> 9
20 >>>>>>>>>>>>>>> 12
Therefore, option B gives the correct table.

The perimeter of the square kitchen floor measures 48 feet what is the area of the kitchen floor
Answer:
the answer is 144 feet
Step-by-step explanation:
to find the how long each sides of the square is divide 48 by 4 (because that's how many sides there are on a square). by doing that you get 12
to find the area of the square you do A= lw which in this case it would look something like this:
A= 12(12) you use 12 twice because square sides are always equal
then you multiply which gives you A= 144
Check whether the given numbers is a solution of the equation or inequality x+9=17;8

Rani is making rice pudding. She uses 3/4 cup of white rice for every 2 cups of milk. how many cups of rice does she need when she uses 3 cups of milk
Answer:
9/4 cups or 2 1/4 cups.
Step-by-step explanation:
Since she uses 3/4 for every 2 cups, then we have to find out what she makes per cup. We have to divide 3/4 in half and to do that, we want to scale up 3/4 making it 6/8 which is congruent to 3/4.
Now we divide 6/8 in half which is 3/8.
Then we multiply that by 3, 6 times 3 is 18. So now it is 18/8 cups. We can now scale down and simplify it more.
To do that, we just divide the fraction by 2 to make to denominator into 4. Because of that, our answer is 9/4 cups or 2 cups and 1/4 cup.
Cups of rice uses for every 3 cup of milk is [tex]1\frac{1}{8}[/tex] cups
Given:
Cups of rice uses for every 2 cup of milk = 3/4 cup
Find:
Cups of rice uses for every 3 cup of milk
Computation:
Cups of rice uses for every 1 cup of milk = (3/4) / 2
Cups of rice uses for every 3 cup of milk = [3 / 8]3
Cups of rice uses for every 3 cup of milk = 9 / 8
Cups of rice uses for every 3 cup of milk = [tex]1\frac{1}{8}[/tex] cups

Mr. Bell wants to plant a rectangular garden in his backyard. He has 100 feet of fence to
enclose his garden. He wants the length to be 5 feet more than the width. What are the
dimensions, in feet, of the garden?
What is the total LENGTH in feet?
Answer:
The dimensions of the garden are 22.5ft by 27.5ft
Step-by-step explanation:
Here, we want to calculate the dimensions of the garden.
let the length be x ft
we are told that the he wants the length to be 5 feet more than the width;
That means the width will be (x-5) ft
Mathematically;
Since the shape is rectangular, the perimeter will be 2( l + w)
Thus; 2(x + x-5) = 100
2(2x-5) = 100
divide both sides by 2
2x-5 = 50
2x = 50 + 5
2x = 55
x = 55/2
x = 27.5 ft
The width is thus; 27.5ft - 5ft = 22.5ft
the dimensions of the garden are 27.5 ft by 22.5 ft
Which of the following is the valid classification of the system given below?
$ 7x + 2y = 24
| 2x + 1 = y
Answer:
Step-by-step explanation:
The system of equation given is a simultaneous equation
7x + 2y = 24 ...... 1
2x + 1 = y ......... 2
Rearrange
7x + 2y = 24 .... *1
| 2x - y = -1 ..... * 2
Use elimination method
7x + 2y = 24
4x - 2y = -2
add
7x+4x = 24-2
11x = 22
x = 22/11
x = 2
Substitute x = 2 into 2
2x+1 = y
y 2(2)+1
y = 4+1
y = 5
Hence x = 2, y = 5
The system of equation is a simultaneous equation

Darcie wants to crochet a minimum of 3 blankets to donate to a homeless shelter. Darcie crochets at a rate of {1}{15} start fraction, 1, divided by, 15, end fraction of a blanket per day. She has 60 days until when she wants to donate the blankets, but she also wants to skip crocheting some days so she can volunteer in other ways. Write an inequality to determine the number of days, sss, Darcie can skip crocheting and still meet her goal.
Answer:
s ≤ 60 - (3 ÷ 1/15)
Step-by-step explanation:
Minimum of blankets to crochet = 3
She has 60 days to crochet
She crochet at a rate of 1/15 of a blanket per day
Therefore to crochet 1 blanket
Number of days needed =x
1 blanket = rate per day * x days
1 = 1/15 * x
1 = 1/15x
Divide both sides by 1/15
x = 1 ÷ 1/15
= 1 × 15/1
= 1×15
x = 15
15 days needed to crochet 1 blanket
To crochet 3 blanket = 15 days × 3 blanket
=45 days needed.
Darcie can skip = 60 days - 45 days
= 15 days
The inequality to determine the number of days, s, Darcie can skip crocheting and still meet her goal.
s ≤ 60 - (3 ÷ 1/15)
Solving the inequality
s ≤ 60 - (3 ÷ 1/15)
s ≤ 60 - (3×15/1)
s ≤ 60 - 45
s ≤ 15
Answer:
s ≤ 60 - (3 ÷ 1/15)
