Answers

Answer 1

Answer: Antonio and Josue have 40 tickets left

Step-by-step explanation:

2 x ( 3 x 15 ) + ( 2 x 10 )

3 x 15 = 45

2 x 10 = 20

2 x 45 = 90

90 + 20 = 110

150 tickets is what they started with and they used 110 tickets 150 - 110 equals 40

Answer 2

It should be 110

2 x ( 3 x 15 ) + ( 2 x 10 )

3 x 15 = 45

2 x 10 = 20

2 x 45 = 90

90 + 20 = 110

110 = 40

Answers

Answer:

10h=m or if you not at that math level yet it would times Hx10=M

Step-by-step explanation:

Answer:

m = 9h

Step-by-step explanation:

you can see that in 5 hours she earns 45 dollars

divide 5 hours by 5 and 45 dollars also by 5

you then find that in 1 hour she earns 9 dollars

so in h hours she earns 9 times h

which is h = 9h

but in this case it asks for money so it is m = 9h (h is how much hours she worked)

Screen-printing a batch of shirts requires 3 minutes per shirt in addition to 16 minutes of initial set-up time. If it takes 31 minutes to screen-print a batch of shirts, how many shirts are in the batch?

Answers

Answer:

The 16 comes from the fact that we take 16 minutes to set up

Step-by-step explanation:

Answer:

The answer is 5 shirts per batch.

Step-by-step explanation:

If you subtract 16 from 31 you get 15.

And because you make 1 shirt per 3 mins, you can divide 3 from 15 and that would get you to 5.

So basically you need to do 2/3x+1/2x=5 then you need to add the Xs so convert to 6 which would be 4/6x plus 3/6x = 9/6x then you have 9/6x = 5 then sub which becomes x = 5 times 6/9 x=30/9

What would be the perimeter of an image if a scale factor of 5 was applied?

Answers

Answer:

Step-by-step explanation:

So first if it was a scale factor 5 you would multiply it by 5 for each side. So for the side of 8 you would multiply it by 5 which is 40 so that side and the other side across from it would also be 40 units. Then for the next one there is 12 units so you do the same 12x5 is equal to 60 so will the one below it.

Then it would be (40 * 2) + (60 * 2)= 80 + 120= 200

So then the perimeter would be 200 units.

First, multiply the length and width each by 5.
12 x 5= 60
8 x 5= 40
For perimeter, add length + length + width + width.
60+60+40+40= 200.
200 ft.

Another way would be to find the perimeter
12+8+12+8= 40
40 x 5= 200
200 ft.
Hope this helps!!

A mountain road is 5 miles long and gains elevation at a constant rate. After 2 miles, the elevation is 5500 feet above sea level. After 4 miles, the elevation is 6200 feet above sea level.
What would be the equation of this line?

Find the elevation of the road at the point where the road begins.

Describe where you would see the point in part (a) on a graph where represents the elevation in feet and represents the distance along the road in miles.

Answers

Answer:

I hope this helps

Step-by-step explanation:

The elevation of the road 4800 feet at the beginning and it gains elevation at a constant rate of 350 feet per mile.

A linear equation is in the form:

y = mx + b;

where m is the rate of change, b is the initial value of y and y, x are variables.

Let y represent the elevation of the road after x miles.

After 2 miles, the elevation is 5500 feet above sea level. Hence:

5500 = 2m + b (1)

After 4 miles, the elevation is 6200 feet above sea level. Hence:

6200 = 4m + b (2)

Solving equation 1 and 2 simultaneously gives:

m = 350, b = 4800

The elevation of the road 4800 feet at the beginning and it gains elevation at a constant rate of 350 feet per mile.

A merchant offers a large group of items at 32% off. Later, the merchant takes 16% off these sale prices and claims that the final price of these items is 186 off the original price. What is the total percent discount?

Answers

Answer:

56 % of original price or 44 % off

Step-by-step explanation:

x times 0.7 times 0.8 = .56x

The total percent discount is 42.88%.

What is a percentage?

A ratio or value that may be stated as a fraction of 100 is called a percentage. Moreover, it is indicated by the symbol "%."

Let's assume that the original price of an item is 100 dollars.

After the first discount of 32%, the price of the item becomes:

100 - (32% of 100) = 68 dollars

After the second discount of 16%, the price of the item becomes:

68 - (16% of 68) = 57.12 dollars

So the final discount on the original price is:

100 - 57.12 = 42.88 dollars

To find the total percent discount, we need to calculate what percentage 42.88 dollars is of the original price of 100 dollars:

(42.88 / 100) x 100% = 42.88%

Therefore, the total discount is 42.88%.

26/3 - (19/5 + 139/15)
