Answer:

the number of t-shirts sold to breakeven is 56 t-shirts

Step-by-step explanation:

The computation of the number of t-shirts sold to breakeven is shown below:

= Fixed cost ÷ (Selling price - cost price)

= $350 ÷ ($10 -  $3.75)

= $350 ÷ 6.25

=  56 t-shirts

Hence, the number of t-shirts sold to breakeven is 56 t-shirts

Answer:

For s students, at least 6s liters of water will be needed. So, for 30 students, at least 6*30 = 180 liters of water will be needed.

Step-by-step explanation:

This question is solved by proportions, using rule of three.

I am going to say that:

s is the number of students.

l is the number of liters of water needed for s students.

I have found that with five students in the class at least 30 litres of water is needed.

This means that:

[tex]\frac{s}{l} = \frac{5}{30}[/tex]

[tex]5l = 30s[/tex]

[tex]l = \frac{30s}{5}[/tex]

[tex]l = 6s[/tex]

This means that for s students, at least 6s liters of water will be needed. So, for 30 students, at least 6*30 = 180 liters of water will be needed.

Answer:

X=50

Step-by-step explanation:

x is the angle

180 - x is its suplement

90 - x is its complement

(180 - x) - 3(90 -x) = 10

180 - x -270 +3x = 10

-90 + 2x = 10

2x = 100

X = 50

Answer:

We have,

3+4(w+5)

=31 Or, 3+20+4w

=31 or, 4w

=31−23

w=8/4

Thus, w comes out to be 2 .

Step-by-step explanation:

Hope it is helpful....

Answer:

w=2

Step-by-step explanation:

3 + 4(w + 5) = 31

distribute 4(w + 5)

4 x w = 4w

4 x 5 = 20

rewrite your equation

3 + 4w + 20 = 31

add like terms

3 + 20 = 23

rewrite equation

4w + 23 = 31

subract 23 on both sides

4w + 23 = 31

-23 -23

4w = 8

divide by 4 on both sides to get w by itself

4w = 8

4      4

w = 2

Answer:

The half-life (t1/2) is the time taken for the activity of a given amount of a radioactive substance to decay to half of its initial value.

P/S 1: Are you sure that your question is related to maths?

+ Bonus: The half-life can be calculated from the decay constant as follows: half-life = ln (2) / (decay constant).

P/S 2: Not sure which is right tho:( Really sorry about that.

Answer:

1. 9 minutes

Step-by-step explanation:

1. If she runs 5 miles in 45 minutes, you have 5 miles = 45 minutes. If you divide both sides of this ratio by 5, you get 1 miles = 9 minutes

2. Find out how many each person sells per week:

Emily: 4 boxes = 2 weeks

divide both sides by 2

2 boxes = 1 week

Jose: 9 boxes = 3 weeks

divide both sides by 3

3 boxes = 1 week

This means that jose sells more, because 3 boxes > 2 boxes

Answer:

230.33333.

Step-by-step explanation:

To know how much 691/3 is in long division, the following mathematical calculation must be performed, taking into account that long divisions seek to divide both the whole numbers and the decimals of the number:

691/3 = 230 (1 left over)

1/3 = 0.333333

230 + 0.33333 = 230.33333

Therefore, 691 divided by 3 results in 230.33333.

Step-by-step explanation:

because both angles are vertical they are equal to each other

lets solve 3x+50=6x-10

add 10 to 60

3x+60=6x

subtract 3x from 6x

60=3x

divide 3 on both sides

20=x

X=20

Answer\Step-by-step explanation:

0≤(x − y)^2 ⟹ 0≤x^2−2xy+y^2

                  ⟹ 2xy≤x^2+y^2

             ⟹ xy≤ x2+y2\2

                  ⟹ xy≤ x^2+y^2

since the clearly nonnegative real x^2+y^2

clearly satisfies x^2+y^2\2  ≤x^2+y^2.

The proof of the quadratic equation  (x-y)²=x²-2xy+y²​ is given.

For variable x : ax² + bx + c = 0, where a≠0 is a standard quadratic equation, which is a second-order polynomial equation in a single variable. It has at least one solution since it is a second-order polynomial equation, which is guaranteed by the algebraic basic theorem.

Given:

Quadratic equation

(x-y)²=x²-2xy+y²​

To prove the equation:

We substitute the value and see if LHS = RHS.

In the LHS,

LHS =  (x-y)²

LHS =  (2-1)²

LHS =  1

In the RHS,

RHS = x²-2xy+y²​

RHS = 4 - 4 + 1

RHS = 1

LHS = RHS​

Therefore, the theorem (x-y)²=x²-2xy+y²​ is proved.

Answer:

13.01d - 2.65

Step-by-step explanation:

DON'T IGNORE THIS PART!!!

Hmmm... in order to be able to solve these type of expressions and more complex ones, we need to know what like terms are in the first place.

Well, the best definition of like terms is: Terms that have the same exact variables.

Let's see the terms that have the same exact variables! They are 3.26d and 9.75d.

By the way, before we continue--I would like to mention something extremely important: 3.26d and 9.75d are positive, whereas -2.65 is negative (you know, the negative sign appears right before it).

Now, let's add 3.26d and 9.75d. It equals 13.01d.

Answer:

350

Step-by-step explanation:

you do length•width•height. so

10•7=70 and 70•5=350

Answer:

Step-by-step explanation:

tanθ = h/250

h = 250tanθ

The height h in feet of the beam as a function of the angle of inclination from Tyler's position to the steel beam is h = 250 tanθ feet

"The angle inclination of a line is the angle formed by the intersection of the line and the x-axis."

"The trigonometric functions are real functions which relate an angle of a right-angled triangle to ratios of two side lengths."

We have

Adjacent side = 250 feet

From the figure,

We can write trigonometric function

Tanθ = [tex]\frac{AB}{BC}[/tex]

Tanθ = [tex]\frac{h}{250}[/tex]

⇒ h = 250 tanθ feet

Hence, The height h in feet of the beam as a function of the angle of inclination from Tyler's position to the steel beam is h = 250 tanθ

Step-by-step explanation:

Answer:

Results are below.

Step-by-step explanation:

1. First, we need to calculate the Future Value:

FV= {A*[(1+i)^n-1]}/i

A= quarterly deposit

n= 10*4= 40

i= 0.12/4= 0.03

FV= {4,000*[(1.03^40) - 1]} / 0.03

FV= $301,605.04

Now, the present value:

PV= FV/(1+i)^N

PV= 301,605.04/(1.03^40)

PV= $92,459.09

2. First, we need to calculate the value of the first year of college:

FV= PV*(1+i)^n

FV= 24,000*(1.04^3)

FV= $26,996.74

Now, the quarterly payments:

FV= {A*[(1+i)^n-1]}/i

A= quarterly deposit

Isolating A:

A= (FV*i)/{[(1+i)^n]-1}

i= 0.08/4= 0.02

n= 3*4= 12

A= (26,996.74*0.02) / [(1.02^12) - 1]

A= $2,012.87

Answer:  700 square inches

===============================================================

Explanation:

The dimension 25 bumps up to 25+5+5 = 35 since we add two copies of 5 onto it. This is done to account for the portions that hang off the edge.

Similarly, the 10 inch dimension bumps up to 10+5+5 = 20 inches.

The table cloth is 35 inches by 20 inches to give an area of 35*20 = 700 square inches.

Side note: 700 square inches is approximately equal to 4.861 square feet (divide by 144 to convert from square inches to square feet).
