hiii help i will put brainliest!

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

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

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

Here you are . i think thais is the asnwer

Answer:

0.21

Step-by-step explanation:

7/33

You take the amount of yellow skittles and divide by the amount of skittles there

Answer:

=.21

7 divided by 33

You take the amount of yellow skittles and divide by the total amount of skittles.

The time is more as the more distance is travelled

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.

Answer:

Where is the area of the whole triangle tho-

Step-by-step explanation:

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

Answer:

Betty will need 34 jars in total to hold all the pears and apples.

Step-by-step explanation:

Betty will need 13 jars for the pears, using division.

104/8 = 13

Same method for the apples.

126/6 = 21

21 + 13 = 34

Total = 34

Answer: What

Step-by-step explanation:

Answer:

i dont know im only doing it for the points

Step-by-step explanation:

Sophia's polygon is, ''5 - sided polygon'' or ''Pentagon.''

Any triangle is a three sided polygon, which has three vertices and three angles which has the sum 180 degrees.

We have to given that;

The minimum number of triangles needed to construct the polygon Sophia made is 3.

And, To find Sophia's polygon.

Now, We know that;

The Shape of Pentagon is made with 3 triangles.

Hence, Sophia's polygon is known as,

⇒ 5 - sided polygon or Pentagon.

Therefore, We get;

⇒ The polygon make by Sophia's is, Pentagon.

Step-by-step explanation:

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.

Answer option C is correct.
