HELP PLZZ I FORGOT HOW TO DO THIS!!!! What is the surface area of the square pyramid represented by the net?
Enter your answer in the box.
Answers
Answer:
39[tex]ft^{2}[/tex]
Step-by-step explanation:
Area of a triangle = [tex]\frac{1}{2}[/tex] × base × height
All four triangles are similar. So finding the area of one triangle, will be the area of the other triangles.
[tex]\frac{1}{2}[/tex] × 3 × 5 = 7.5[tex]ft^{2}[/tex]
∴ The area of 4 triangles are 7.5 × 4 = 30[tex]ft^{2}[/tex]
Then the only shape remaining is the square.
Area of the square = [tex]length^{2}[/tex] (all the sides of a square are equal)
= [tex]3^{2}[/tex] = 9[tex]ft^{2}[/tex]
Total surface area = 30 + 9 = 39[tex]ft^{2}[/tex]

Step-by-step:
Dozen flyers:price
4:7.25
12:x
To solve this mulitply 7.25 by 3 (because this is what we multiplied 4 by to get 12) 7.25*3=21.75
Question 2:
We can write teh following equation
.49+.22(x-1)=price
This is essentially saying that we pay .49 for the first ounce and .22 for every ounce after that
We can plug in an x value to get
.49+.22(5-1)
.49+.22(4)
.49+.88
1.37
Question 3:
We can write the following equation
x+2=y
We need to find out what happens when x=8
8+2=10
Question 4:
We can solve this with ratios
x:y
1.5:4.5
5:x
To solve just multiply 4.5 by 10/3 and get 15
We can just multiply
Answer:
1. 7.25/4=1.8125 so 1.8125x12=21.75
2. 0.49+(0.22x4)=1.37
3. rule is x+2=y so x=8 then y=10
4.rule is 3(x)=y so x=5 then y=15

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
