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

Answer:
The answer is 0.045
Step-by-step explanation:
1. Use this formula V=lwh
0.5 x 0.4 x 0.15 = 0.03
That is the volume of the lower prism
2. Do V=lwh again for the volume of the upper prism
0.5 x 0.15 x 0.2 = 0.015
3. After that add both of them up together
0.015 + 0.03 = 0.045

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.
Answer option C is correct.
Hi I need help with this problem. But it has to be shown with work. Does anyone know?
x : 6 = 10 : 150
Answers
Answer:
its is 90
Step-by-step explanation:
6x10=60 150-60=90
Answer:
0.4 or 2/5???
Step-by-step explanation:
I believe this is a proportion/ratio problem.
Think of it like this:
x/6 = 10/150
To solve for x, you must cross multiply:
150x = 6*10 (150x... DON'T write 150*x, that is nonsense)
150x = 60
x = 60/150 (you divide because you are actually dividing 150 on both sides and doing the opposite operation of multiplication)
x = 6/15
x = 2/5 or 0.4 (I simplified it)
Hopefully this helped? I can't seem to find a whole number answer... so the only options I could do are 2/5 or 0.4
please help I don't understand I don't want the answer I want an explanation

I have a triangle: Angle A = 3x +28; Angle B = 5x +52; Angle C = 2x - 10: Solve for X
Answers
Explanation: The anglers in a triangle must all add to 180.
Therefore, we can use the equation 180=3x+28+5x+52+2x-10
Combing like terms gives us 180=10x+70
Solving for x gives us 11.
To check our work, we can plug in 11 for x.
3(11)+28+5(11)+52+2(11)-10=180.
