Answer:

2.73     8.75

Step-by-step explanation:

n = 1  

1 (DOUBLE) = 1+1 = 2  

2 +3/4 = 1.5

1.5 +2 = 3.5  

3.5 x 0.22 = 0.77

3.5 - 0.77 = 2.73

n = 1

1 + 3/4 = 1 + 0.75 = 1.75

1.75 (DOUBLE) = 3.5

3.5 x 2 1/2 = 8.75

2.72 8.75 good luck :)))

Where is the area of the whole triangle tho-

Step-by-step explanation:

Look at the picture and answer the question: What is the length of QS?

Answers

Step-by-step explanation:

firstly draw the triangle and label it. (you will find the picture down)

Now this remind us with the cosine rule. (you will find the picture down)

This rule says that the square of the given length of the side of a triangle is equal to the sum of the squares of the length of other sides minus twice their product and multiplied by the cosine of their included angle.

So using that rule we can say that:

[tex]QS^{2}[/tex] = [tex]QR^{2} +SR^{2} - 2(QR)(SR)(cosR)[/tex]

square root both sides, so you will have QS alone in one side.

QS = [tex]\sqrt{ [QR^{2} +SR^{2} - 2(QR)(SR)(cosR)]}[/tex]

plug in the values we have and y=this will yield:

QS = [tex]\sqrt{ [11^{2} +16^{2} - 2(11)(16)(cos38)] }[/tex] = 9.98099267 = 10

Machine A makes 12.75 ounces of popcorn in 3 minutes. Machine B makes 18 ounces of popcorn in 4 minutes.
If each machine makes popcorn for 10 minutes, will there be enough popcorn for eight 9-ounce bags? Explain.

Answers

Answer:

yes if each machine makes popcorn for 10 minutes, there be enough popcorn for eight 9-ounce bags

Step-by-step explanation:

yes because 12.74 x 3.3 = 42.075 and 18 x 2.5 = 45 and when you add those together you get 87. Also 8  9-ounce bags = 72 and that is less then what you have.

Answer:

Yes there will be enough popcorn for eight 9-ounce bags.

Step-by-step explanation:

" eight 9-ounce bags"

Basically

"72 ounces"

"12.75 ounces of popcorn in 3 minutes"

Basically

We need to find out how much popcorn we can make in "One Minute"

12.75÷3=4.25

Now we need to find out how much it can make in "Ten Minutes"

4.25×10=42.5

"18 ounces of popcorn in 4 minutes."

Basically:

We wanna find out how much it can make in "One Minute"

18÷4=4.5

"makes popcorn for 10 minutes"

Basically:

We need to find out how much popcorn it can make in "Ten Minutes"

4.5×10=45

Add (45) and (42.5)

45+42.5=87.5

So yes,there will be enough popcorn for eight 9-ounce bangs due to the fact A and B makes (87.5) ounces of popcorn and thats greater than (72) ounces.

A car has 15 gallons of gas in its tank. The car travels 35 miles per gallon of gas. It uses 135 of a gallon of gas to go 1 mile. How much gas does it use to go 100 miles?

Answers

2.86 gallons

Step-by-step explanation:

If 1/35 gallon of gas = 1 mile

To travel 100 miles,

1/35 * 100

= 0.0286 * 100

= 2.86 gallons

Therefore, the car needs 2.86 gallons of gas to travel 100 miles

2.86 gallons is the answer

The Wagner school store is having a sale! At the sale this week, a life sized stuffed animal of Wagner’s mascot is being sold for $158.40. This is a 52% discount of the original price. What is the original price? If necessary, round to the nearest cent.

Answers

Divide the sale price by the percentage of the original cost.

Percent of original cost = 100% - 52% = 48 %

158.40 / 0.48 = 330.00

The original price was $330.00

UGH! RSM!!!!!!!!!!!!!!!!!!!!! John's family visited his grandmother over the weekend.

How many miles away is john's grandmother's house? will give BRAINLIEST! +10pts!

Answers

(1)- 30
Hope this helps!

Answer:

90 miles!

Step-by-step explanation:

there are two parts to the problem, meaning you'll need 2 equations.

let's call the distance TO the grandma's house d1, and BACK from the grandma's house d2.

KEY:

time TO g'ma house= t1

time FROM g'ma house=t2

(replace the t's with 's' for speed, with the '1' for to, and '2' for from)

(distance is a constant so d1 is always equal to d2).

-------------

d1=s1+t1, d2=s2+t2

we know what t1 is. 2 hours.

d1=s1•2

meaning that d2 is also equal to that.

s1•2=(s1-5)•2 1/4

2s1=2 1/4 s1-11 1/4

11 1/4= 2 1/4 s1-2s1

11 1/4 = 1/4 s1

s1 (to g'ma)=45 mph

distance is speed times time.

so 45•2 (hr) = 90.
