The width of a rectangle is the sum of the length and 2. The area of the rectangle is 48 units. What is the width, in units, of the rectangle?
Answers
W=L+2
A=48=L*W
48=L*(L+2)
48=L^2+L*2
0=L^2+L*2-48
L1=6
L2=-8 (can't be used since it's negative)
Lenght=6
Width=8
To Start Off:
Level: Middle School
Subject: Mathematics
Lesson: Area Problems
To Set The Problem Up:
You set the problem up as A or 48 = L + 2 x L
To Find The Answer:
What are 2 factors that equal 48 that are Reasonable for this problem?
Maybe 6 and 8?
6 must be the length because the width is larger by +2.
To Solve/Work:
So L= 6 and L + 2 = W, 6 + 2= 8.
This means that Length equals 6 and Width equals 8.
Our 2 factors were correct!
Next, to find the area, we must multiply 6 and 8 to get A.
The Formula: L x W = A
So 6 x 8 = 48.
To Sum It Up:
Our final answer is 48 and it takes finding factors of the total, the area.
Most problems only give out 2/3 parts of our Formula. They want to trick you.
To put on the bow, we learned how to use the formula, which is L x W = A or A = L x W.

Answers
Answer D). 9 ft is correct
Height of the ball at a horizontal distance of 10 feet is 9 ft
Step-by-step explanation:
A ball is thrown and it follows a parabolic path. At each horizontal distance (x) the following equation models the ball’s height (y).
Y(x) = [tex]-0.02x^{2} +0.8x+3[/tex]
Question asked is " What will be height (Y) of the ball when X=10 ft "
Simply putting value of X in given equation
we get,
Y(x) = [tex]-0.02x^{2} +0.8x+3[/tex]
Y(x) = [tex]-0.02(10)^{2} +0.8(10)+3[/tex]
Y(x) = [tex]-0.02(100)} +8+3[/tex]
Y(x) = [tex]-2 +8+3[/tex]
Y(x) = [tex]9[/tex]
Therefore, Height of the ball at a horizontal distance of 10 feet is 9 ft
Answer D. 9 ft is correct
The height of the ball at a distance of 10 feet according to the given equation is 9 feet (option D). This was achieved by substituting the value of 10 into the equation.
Explanation:To find the height of the ball at a distance of 10 feet, you need to substitute the value for the horizontal distance (x) in the given equation. The equation modeling the ball's height is: Y=-0.02x^2+0.8x+3. So, we replace x with 10 in this equation, as follows:
Y=-0.02(10)^2+0.8(10)+3 Y=-0.02(100)+8+3 Y=-2+8+3 Y=9
Therefore, the height of the ball at a distance of 10 feet is 9 feet, so option D is correct.

The volume of one cube is 1/216 times the volume of the second cube. How many more times
is the length measurement of the second cube?
A 21 times
B 16 times
C 6 times
D 4 times
Answers
Answer:
c 6 times that the answer
Final answer:
The second cube's side length is 6 times that of the first cube because the volume of a cube is a cubic function of its side length, and taking the cube root of 1/216 gives us 1/6.
Explanation:
The student's question is asking to determine how many times larger the side length of the second cube is compared to the first cube, given that the volume of the first cube is 1⁄216 times the volume of the second cube. The volume of a cube is calculated by raising the side length to the third power (V = s3). Therefore, if we denote the side length of the first cube as s and that of the second cube as S, we have s3 = 1⁄216S3. To find the side length ratio, we take the cube root on both sides of the equation, yielding s = 1⁄6S, which means the second cube's side length is 6 times that of the first cube.
The correct answer to the question is C, 6 times

in a recent study, 55% of the cars tested failed the safety test. If 231 cars failed the safety test, how many cars were tested
Answers
Answer:
420 cars were tested
Step-by-step explanation:
55/100=231/x
55x= 23100
x=420
Final answer:
The total number of cars tested can be calculated by dividing the number of cars that failed (231) by the percentage that failed (55%), resulting in 420 cars tested.
Explanation:
The question asks about the total number of cars tested based on the percentage that failed the safety test. To find the total, we can set up a proportion: if 55% of cars, or 0.55 of the total, failed the safety test and that number is 231, we can represent the total number of cars tested as 'X'. Using the proportion 0.55 = 231/X, we can solve for X, which represents the total number of cars tested.
Step by step, we can start by multiplying both sides of the equation by X to get 0.55X = 231, then we divide both sides by 0.55 to isolate X and find the total:
X = 231 / 0.55
X = 420
Therefore, 420 cars were tested.

Find the slope intercept form of the equation of the line that passes through (-5,3) and is parallel to 12x-3y=10
Answers
Answer:
y=4x+23
Step-by-step explanation:
The slope-intercept form of the equation of the line that passes through (-5,3) and is parallel to 12x-3y=10 is y = 4x + 23.
What is a slope?In mathematics, a line's slope, also known as its gradient, is a numerical representation of the line's steepness and direction.
Slope-intercept form:
y = mx + b, where m is the slope and b is the y-intercept.
And we have the given equation:
12x - 3y = 10
Arranging the equation as slope-intercept form.
3y = 12x - 10
Divide by 3,
y = 4x - 10/3.
And this line is parallel to the required line.
So, the slope of the required line;
m = 4
Hence, the slope-intercept form,
y = 4x+b equation 1
To find y-intercept:
We substitute the value of x and y from the point (-5,3) to the slope-intercept form,
y = 4x + b
(3) = 4(-5) + b
b = 20 +3
b = 23
Now, the equation 1
y = 4x + 23
Therefore, y = 4x + 23 is the required slope-intercept form.

If 8 cases of merchandise cost 60$, what would a dozen cases cost?
Answers
60 divided by 8 - 7.5
7.5 x 12 - 90
Answer: $90
Step-by-step explanation: First, we can change "one dozen" to 12 since it represents the same value.
To find out how much 12 cases of merchandise will cost, we will need to find the unit price per case of merchandise.
Unit price means the cost per unit in this case, the cost per case of merchandise.
Since we know that it costs $60 for 8 cases of merchandise, to find the cost for 1 case of merchandise, we need to divide 8 into $60 or $60 ÷ 8.
60 ÷ 8 = 7.50
Now, we know that it costs $7.50 for 1 case of merchandise.
To find the cost for 12 cases of merchandise, we will multiply the cost for 1 case of merchandise by the number of cases of merchandise we have.
In this case, we will multiply 7.50 by 12 which gives us 90.
Therefore, a dozen cases of merchandise will cost $90.

What is the probability of the coin landing heads up?
A. 1/2
B. 1/4

D. 1/3
Answers
Answer: 1/2
Step-by-step explanation: In this problem, we're tossing a coin and we want to find the probability of tossing a heads.
Now, let's find the probability of tossing a heads.
Remember that a coin has two sides which are heads and tails. When you flip a coin, each side is as likely to come up as the other. This means that the probability of flipping heads is the fraction 1/2.
Since the probability of flipping a heads is 1/2, we can also say that the probability of flipping a heads is 50%.
Therefore, the probability of flipping a heads on a fair coin is 1/2.

The number of medium pizzas sold is usually twice as many as large ones. How many of each size pizza must they sell to get $600?
Answers
They must sell 18 small pizzas, 12 medium pizzas and 6 large pizzas
Step-by-step explanation:
A Pizzeria sells pizza according to size:
Small pizzas cost $10, medium pizzas cost $15, and large pizzas cost $40They usually sell as many small pizzas as medium and large pizzas combinedThe number of medium pizzas sold is usually twice as many as large onesWe need to find how many of each size pizza they must sell to get $600
Assume that the number of small pizza is x, the number of medium pizza is y and the number of large pizza is z
∵ The Pizzeria sells x small pizzas, y medium pizzas and
z large pizzas
∵ The small pizzas cost $10, medium pizzas cost $15, and
large pizzas cost $40
∵ They get $600
∴ 10x + 15y + 40z = 600 ⇒ (1)
∵ They sell as many small pizzas as medium and large pizzas
combined
∴ x = y + z ⇒ (2)
∵ The number of medium pizzas sold is twice as many as large ones
∴ y = 2z ⇒ (3)
Substitute equation (3) in equation (2) to find x in terms of z only
∵ x = (2z) + z
∴ x = 3z ⇒ (4)
Substitute x in equation (1) by equation (4), and substitute y in equation (1) by equation (3)
∵ 10(3z) + 15(2z) + 40z = 600
- Simplify the left hand side
∴ 30z + 30z + 40z = 600
- Add like terms
∴ 100z = 600
- Divide both sides by 100
∴ z = 6
Substitute the value of z in equations (3) and (4) to find y and x
∵ y = 2(6)
∴ y = 12
∵ x = 3(6)
∴ x = 18
They must sell 18 small pizzas, 12 medium pizzas and 6 large pizzas
