A seamstress was hired to make band uniforms for Hinsdale High school. The seamstress bought 148 yards of material. There were 16 students in the concert band and 20 students in the symphonic band. How much material did she have for each uniform?
A. 36/9 yards
B. 37/9 yards
C. 35/9 yards
D. 38/9 yards

Answers

Answer:

No estoy seguro, intenta preguntarle a tu profesor

Step-by-step explanation:

The seamstress had 37/9 yards of material for each uniform.

What is division?

In mathematics, division is a process of dividing a number into equal parts and calculating the maximum number of equal parts that can be made.

How to solve it?

Given that total amount of material = 148 yards

number of students in the concert band = 16

number of students in the symphonic band = 20

Total number of students = number of students in the concert band + number of students in the symphonic band

= 16 + 20 = 36

For 36 students, there are 148 yards of material.

Then for 1 student, there are 148/36 = 37/9 yards of material.

Therefore the seamstress had 37/9 yards of material for each uniform. So, option B is correct.

Answer:

THANK YOUUU for those who can't see the image its answer choices B , C , and E

Step-by-step explanation:

By using distance formula, JH=VU=√13 units. Therefore, option B, C and E are the correct answers.

Given that, JH=VU.

What is distance formula?

The distance formula which is used to find the distance between two points in a two-dimensional plane is also known as the Euclidean distance formula. On 2D plane the distance between two points (x1, y1) and (x2, y2) is Distance = √[(x2-x1)²+(y2-y1)²].

From the triangle UVW, we have V(5, 2) and U(2, 4).

From the triangle JKH, we have J(-5, -3) and H(-3, 0).

Now,

VU = √[(2-5)²+(4-2)²]

= √13 units

JH = √[(-3-(-5))²+(0-(-3))²]

= √[(-3+5)²+(0+3)²]

= √13 units

By using distance formula, JH=VU=√13 units. Therefore, option B, C and E are the correct answers.

x=-5

Step-by-step explanation:

4(x-5)+2=x+3 As the first step says, distribute the 4 (multiply all numbers in the parentheses by 4).

4x-20+2=x-3 Combine like terms. For example, the -20 and 2 are like terms because they are both their own numbers and not attached to a variable.

4x-18=x-3       Subtract x from each side. Now, we can get x to only one side.

-x       -x

3x-18=-3         Add 18 to both sides.

  +18 +18

3x=-15            Divide both sides by 3.

Piper is deciding between two truck rental companies. Company A charges an initial fee of $35 for the rental plus $3 per mile driven. Company B charges an initial fee of $80 for the rental plus $2 per mile driven. Let AA represent the amount Company A would charge if Piper drives xx miles, and let BB represent the amount Company B would charge if Piper drives xx miles. Write an equation for each situation, in terms of x,x, and determine the interval of miles driven, x,x, for which Company A is cheaper than Company B.

Answers

Answer:

An equation for each situation, in terms of x

A = 35 + 3x

B = 80 + 2x

The interval of miles driven x, for which Company A is cheaper than Company B is 0 to 44.9 miles.

Step-by-step explanation:

Let A represent the amount Company A would charge if Piper drives x miles

Let B represent the amount Company B would charge if Piper drives x miles.

Company A charges an initial fee of $35 for the rental plus $3 per mile driven.

A= $35 + $3 × x

A = 35 + 3x

Company B charges an initial fee of $80 for the rental plus $2 per mile driven.

B = $80 + $2 × x

B = 80 + 2x

The interval of miles driven x, for which Company A is cheaper than Company B.

= A < B

35 + 3x < 80 + 2x

3x - 2x < 80 - 35

x < 45 miles

That is: any number of miles driven below 45 miles makes Company A cheaper than Company B

The interval of miles driven x, for which Company A is cheaper than Company B is 0 to 44.9 miles.

Hailey went to Frank’s Market and bought 1 3/4 pounds of coffee at $13 a pound and 8 1/2 pounds of rice at $0.45 per pound. If Hailey paid for her purchase with a  $50 bill, how much change did she receive?

Answer:

$23.43

Step-by-step explanation:

First, you need to find the total amount she needs to pay for the items she purchased:

1 3/4=1.75

8 1/2=8.5

Total purchase=(1.75*$13)+(8.5*$0.45)

Total purchase=22.75+3.82

Total purchase=26.57

No, you need to subtract the total amount you have to pay for your purchase from $50:

$50-$26.57=$23.43

According to this, the answer is that she received $23.43 as change.

Answer: B- $23.43

Step-by-step explanation:

First, you need to convert:

1 3/4=1.75

8 1/2=8.5

Total purchase- (1.75 x 13) + (8.5 x 0.45) = 22.75 + 3.82 = 26.57

Now you need to subtract the total amount you have to pay for your purchase from the $50.

50 - 26.57 = 23.43!
