You are buying t-shirts for the members of the math club. Each short-sleeve t-shirt costs
$10 and each long-sleeve t-shirt costs $17. If you purchase x short-sleeve t-shirts and y
long-sleeve t-shirts, write an equation to represent the total cost of the purchase.

Answers

Answer 1

Answer:

10x +17y=c (C is the total cost)

Answer 2

Answer:

10x+17y = z

Step-by-step explanation:

You have to multiple 10 by the number of t shirts you have(x)

Then you have to multiply 17 by the number of long sleeve shirts you have (y)

You then have to add 10x and 17y to get your total cost(z)

Find the lenght of side BC. give your answer to 3 significant figures

Answers

Answer:

BC ≈ 19.4 cm

Step-by-step explanation:

Using the cosine ratio in the right triangle

cos71° = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{AB}{BC}[/tex] = [tex]\frac{6.3}{BC}[/tex] ( multiply both sides by BC )

BC × cos71° = 6.3 ( divide both sides by cos71° )

BC = [tex]\frac{6.3}{cos71}[/tex] ≈ 19.4 cm ( to 3 significant figures )

Points Q, R, S, and T are shown on the number line. What is the distance between point Q and point S on the number line?

A) 2 units
B) 4 units
C) 6 units
D) 7 units

Answers

C) 6 units



Point Q is at -4, so to get to Point S, which is at 2, you have to jump 6 units to get from Q to S.
The answer is 6. If you subtract (2)-(-4), make sure to add parentheses, you get 6 so the answer is 6 units

How many years will it takes an investment of 3000$ to amount to 5,000 if money is invested at 4.1% compounded monthly

Answers

Answer:

1.66

Step-by-step explanation:

The years needed to make $3000 to $5000 is 12.5.

What is compound interest?

Compound interest simply means that the interest associated with a bank account, loan, or investment increases exponentially over time.

Given that, an investment of $3000 to amount to 5,000 if money is invested at 4.1% compounded monthly

A = P(1+r/12)^12t

5000 = 3000(1+0.041/12)^12t

5/3 = (1.0034)^12t

Taking log both sides,

log5/3 = 12tlog(1.0034)

0.221 = 12t0.00147

12t = 150.34

t = 12.5

Hence, required years are 12.5.

A rate is a ratio that compares

Answers

A rate is a ration that compares two quantities that have different units of measure. If the second term in rate is 1, the ratio is called a unit rate.

Rate is ratio that compares two quantities of different units.

What is rate?

A rate is a special ratio in which the two terms are in different units. Rate can also be defined as the ratio between two quantities of different units

For example, velocity is an example of rate, because it defined by the ratio of distance covered and time.

The unit of distance is metres and the unit of time is second. Therefore ;

velocity = distance /time. Therefore velocity is a rate.

Another example is ; Ade eat 5 mangoes for 20 days. The rate at which Ade eat is

1 day = 5/20

= 1/4 mangoes. This means Ade eats 1/4 mangoes per day.

Answer:

14. d

15. b

Step-by-step explanation:

steps for #14:

1. complementary angles are angles that equal 90 degrees when added together. so, those two angles equal 90. make an equation to represent this.

  (x + 5) + (x - 9) = 90

2. combine like terms.

  2x - 4 = 90

3. solve for x.

  2x = 94

     x = 47

4. plug x into both formulas to find the measurements of each angle.

  47 + 5    AND     47 - 9  

     d. angle DFG = 52, angle JKL = 38

steps for #15:

1. when angles are linear pairs, it means they equal 180 degrees when added together. so, these two angles equal 180. make an equation to represent this.

  (x - 39) + (x + 61) = 180

2. combine like terms.

  2x + 22 = 180

3. solve for x.

  2x = 158

     x = 79

4. plug x into both formulas to find the measurements of each angle.

  79 - 39    AND      79 + 61

     b. angle 1 = 40, angle 2 = 140

-8-5n=64+3n

Answers

Answer:

n= -9

Step-by-step explanation:

The calculator is correct haha, You're welcome.

Answer:

n=-9

Explanation:
In order to solve for x, we must get x by itself on one side of the equation.
The equation is:
-8-5n=64+3n
5n is being subtracted and the inverse of subtraction is addition. Add 5n to both sides of the equation.
-8-5n+5n=64+3n+5n
-8=64+3n+5n
-8=64+8n
64 is being added and the inverse of addition is subtraction. Subtract 64 from both sides of the equation.
-8-64=64-64+8n
-8-64=8n
-72=8n
n is being multiplied by 8. The inverse of multiplication is division. Divide both sides of the equation by 8.
-72/8=8n/8
-72/8=n
-9=n

The solution to the equation is n=-9

The number of burritos Delainy ate on Tuesday is the same as the number of burritos Louie ate on Wednesday. On Tuesday, Delainey ate 16 more than 1/2 the total number of burritos consumed. On Wednesday, Louie ate 1 less than 3/4 of the total number of burritos consumed. Write an equation to determine the total number of burritos consumed. Hint: let x = # burritos consumed.

Answers

Answer:

The total number of burritos consumed is 68 and an equation to determine the total number of burritos consumed is [tex]\frac{1}{2}x+16=\frac{3}{4}x-1[/tex]

Step-by-step explanation:

Let x be the total number of burritos consumed

We are given that On Tuesday, Delainey ate 16 more than 1/2 the total number of burritos consumed

So, Number of burritos ate by Delainey on Tuesday=[tex]\frac{1}{2}x+16[/tex]

We are also given that  Louie ate 1 less than 3/4 of the total number of burritos consumed.

So, Number of burritos ate by Louie on Wednesday =[tex]\frac{3}{4}x-1[/tex]

We are given that The number of burritos Delainy ate on Tuesday is the same as the number of burritos Louie ate on Wednesday.

So, [tex]\frac{1}{2}x+16=\frac{3}{4}x-1\\1+16=\frac{3}{4}x-\frac{1}{2}x\\17=\frac{x}{4}\\68=x[/tex]

Hence  the total number of burritos consumed is 68 and an equation to determine the total number of burritos consumed is [tex]\frac{1}{2}x+16=\frac{3}{4}x-1[/tex]
