11(x+10)=132
Answer:
11(x+10)=132 x = 2
Step-by-step explanation:
Step 1: Distribute the 11 to the "x" and the "10".
(Equation now becomes 11x + 110 =132)
Step 2: Subtract the "110" over to the "132"
(Equation now becomes 11x=22)
Step 3: Divide the "11" and the "22" --> 11x=22

3.4² + b² = 6.5²
11.56 + b² = 42.25
42.25 - 11.56 = b²
b = √30.69
b = 5.53985559 or about 5.5
4.9² + b² = 5.5²
24.01 + b² = 30.69
30.69 - 24.01 = 6.68
b = √6.68

The Sweater Shack is offering a 20% discount on sweaters. If the regular price of a sweateris $15.00, what is the discount? /There are 30 students in Mrs. Jones class. Twenty percent of the students received an A on the last math test. How many students received an A? / Jean Junction is selling jeans at 15% off the regular price. The regular price is $25.00 per pair. What is the discount?/ if you can answer these Ill do another 100 points but please I really need help
Given that ,
The sweater shack is offering 20% discount,
and the regular price is $ 15 .00,
so, the discount given would be
⇢ $ 15 x 20/100
⇢$ 15 x 0.2
⇢$ 3
selling price⇢Regular price - Discount price
⇢$15 - $(20/100 x 15)
⇢$15 - $3
⇢$12
Answer 2↷Given that,
20% out of 30 students scored an A in previous math test,
so ,the number of students who got an A in the test
⇢ 30 x 20/100
⇢30 x 0.2
⇢6
Hence ,6 students secured an A grade in last math test
Answer 3↷Given that,
The Jean junction is selling the jeans at the discount rate of 15% of the regular price which is $25.00,
so, the discount is
⇢$25.00 x $ ( 15/100 )
⇢$25.00 x $ 0.15
⇢$3.75
selling price⇢ $25.00 - $25.00 x $ ( 15/100 )
⇢$25.00- $25.00 x $ 0.15
⇢$25.00 -$3.75
⇢$21.25
The local water supply has a leak, it is losing 4 gallons of water every second.
After 15 seconds, the water level is at 1024 gallons. Write an equation to
represent the situation: *
Answer:
An equation to represent the situation would be:
[tex]y = 4x + 964[/tex]Step-by-step explanation:
Given that the water supply is losing 4 gallons of water every second.
It means the rate of change = 4 gallons per second
Given that after 15 seconds, the water level is at 1024 gallons.So the equation becomes
1024 = 4(15) + b
comparing with the slope-intercept form of the equation of a line
[tex]y = mx+b[/tex]
where m is the slope (rate of change) and b is the y-intercept
so
[tex]1024 = 4(15) + b[/tex]
[tex]1024 = 60 + b[/tex]
[tex]1024 - 60 = b[/tex]
[tex]b = 964[/tex]
So, the value of y-intercept i.e b=964
Thus, the equation will be
[tex]y = mx+b[/tex]
substituting the value rate of change i.e m = 4 and b=964
[tex]y = 4x + 964[/tex]
Therefore, an equation to represent the situation would be:
[tex]y = 4x + 964[/tex]A 220-inch pipe is cut into two pieces. One piece is four times the length of the other. Find the length of the shorter piece.
The shorter piece is
inches long
Answer:
let x be the length of the shorter piece.
4x + x= 210
x= 42.
4x= 168
The shorter piece is 42in and the long piece is 168 in.
The length of the shorter piece will be;
⇒ x = 44 inch
What is linear expression?
A linear expression is an algebraic statement where each term is either a constant or a variable raised to the first power.
Given that;
A 220-inch pipe is cut into two pieces.
And, One piece is four times the length of the other.
Now,
Since, One piece is four times the length of the other.
Let height of shorter piece = x
Then, The height of longer piece = 4x
Hence, We can formulate;
⇒ x + 4x = 220
Solve for x as;
⇒ 5x = 220
⇒ x = 220 / 5
⇒ x = 44
Thus, The length of the shorter piece will be;
⇒ x = 44 inch

A dozen water bottles cost $5.88. How much would it cost to purchase 36 bottles of water?
if I have a bottling machine that fills 15 bottles of water every 6 seconds, what is my unit rate and what would be my slope on a graph?
Answer:
Please check the explanation.
Step-by-step explanation:
We know that the unit rate is termed as the slope of the line.
We also know that the slope is normally represented by a fraction which may be expressed as a unit rate found at the point on the graph.
We are given that a bottling machine fills 15 bottles of water every 6 seconds.
We want a unit rate where 1 is in the denominator.Thus,
unit rate = 15 bottles / 6 seconds
= 2.5 bottles / 1 second
= 2.5 bottles per second
Thus,
The unit rate = 2.5 bottles per second
We know that the unit rate represents the slope of the line which is normally represented by a fraction or ratio.
Therefore,
Slope = 15 / 6
= 2.5

Prove that the measure of angle JKL is 90 degrees.
∡ NKM + ∡KNM + ∡ NMK = 180° Because Angles in a triangle ΔNKM sum to 180°
∡ NKM + 90° + 60° = 180°
∡ NKM = 30°
∡ NKM = ∡JKN = ∡ MKL = 30° because ΔJKM∼ΔNKM∼ΔMKL
Finally:
∡ JKL = ∡ NKM + ∡JKN + ∡ MKL
∡ JKL = 30° + 30° + 30°
∡ JKL = 90°
With the help of properties of triangle ∠JKL = 90 degrees.
To prove:
∠JKL = 90 degrees.
Here,
Angle sum property of triangle:
In any triangle sum of angles is 180 degrees.
So,
In ΔNKM
∡ NKM + ∡KNM + ∡ NMK = 180°
∡ NKM + 90° + 60° = 180°
∡ NKM = 30°
Now,
ΔJKM∼ΔNKM∼ΔMKL (By AAA)
Thus,
∡ NKM = ∡JKN = ∡ MKL = 30°
Next,
∡ JKL = ∡ NKM + ∡JKN + ∡ MKL
∡ JKL = 30° + 30° + 30°
∡ JKL = 90°
Hence proved.

Part A. The Toyota uses 21 miles per gallon.
Part B. The Toyota can go 315 miles using 15 Gallons.
Step-by-step explanation:
P.S Can I have brainliest?
The new Toyota can travel 315 miles with 15 gallons of gas.
Given that, the new Toyota can go 15 3/4 miles on 3/4 of a gallon of gas.
What is the unitary method?The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.
A) Here, 15 3/4 miles can be written as 63/4
Now, the mileage = 63/4 ÷ 3/4
= 63/4 × 4/3
= 21 miles per gallon
B) Number of miles travelled with 15 gallons
= 21 × 15
= 315 miles
Hence, the new Toyota can travel 315 miles with 15 gallons of gas.

350cm³ to 1 litre as a ratio in its lowest terms
We need to know about ratio to solve the problem. The ratio of 350[tex]cm^{3}[/tex] to 1 litre as a ratio in its lowest terms is 7:20.
Ratio is the measure of how many times one number contains another in it. We can find the ratio of one quantity to another by dividing one by the other by cancelling out the common factors between the two. We have to find the ratio of 350[tex]cm^{3}[/tex] to 1 litre in its lowest terms. The lowest terms for both the quantities is [tex]cm^{3}[/tex]. We know that 1 litre =1000[tex]cm^{3}[/tex], we will convert the 1 litre to 1000[tex]cm^{3}[/tex] for calculating the ratio.
The ratio of 350 [tex]cm^{3}[/tex] to 1 litre =350/1000=35/100=7/20= 7:20
Therefore we found the ratio of 350 [tex]cm^{3}[/tex] to 1 litre in its lowest terms to be 7:20 by using the concept of ratio.

Step-by-step explanation:
Ann and Ruth bowled together and had a combined score of 410 points. Ann's score was 44 points less than Ruth's score. Write a system of equations that can be used to determine x, Ann's score and y, Ruth's score.
Answer:
x=y-44 and x+y=410
Step-by-step explanation:
So, you want to use the equations x=y-44 and x+y=410 when x is Ann's score and y is Ruth's score. This is because x (Ann's score) is Ruth's score (y) but 44 less, so you subtract y-44 to get x. Then x+y would also have to equal 410 so that's the other equation. Graphing the 2 equations gets you to the point (183,227) in which Ann's score is 183 points and Ruth's score is 227 points.
