Answers

Answer:

Part 2) Option b. 5.4

Part 3) Option c. 8

Part 4) Option a. 15

Part 5) Option d. 8.9

Step-by-step explanation:

Part 2) Find the value of x to the nearest tenth

we know that

x is the radius of the circle

Applying the Pythagoras Theorem

x^(2)=3.6^(2)+(8/2)^(2)

x^(2)=28.96

x=5.4\ units

Part 3) Find the value of x

In this problem

x=8

Verify

step 1

Find the radius of the circle

Let

r -----> the radius of the circle

Applying the Pythagoras Theorem

r^(2)=8^(2)+(15/2)^(2)

r^(2)=120.25

r=√(120.25)

step 2

Find the value of x

Applying the Pythagoras Theorem

r^(2)=x^(2)+(15/2)^(2)

substitute

120.25=x^(2)+56.25

x^(2)=120.25-56.25

x^(2)=64

x=8\ units

Part 4) Find the value of x

In this problem

x=OP=15

Verify

step 1

Find the radius of the circle

Let

r -----> the radius of the circle

In the right triangle FPO

Applying the Pythagoras Theorem

r^(2)=15^(2)+(40/2)^(2)

r^(2)=625

r=25

step 2

Find the value of x

In the right triangle RQO

Applying the Pythagoras Theorem

25^(2)=x^(2)+(40/2)^(2)

625=x^(2)+400      

x^(2)=625-400

x^(2)=225

x=15\ units

Part 5) Find the value of x

Applying the Pythagoras Theorem

6^(2)=4^(2)+(x/2)^(2)

36=16+(x/2)^(2)

(x/2)^(2)=36-16

(x/2)^(2)=20

(x/2)=4.47

What is the tax (8%) on a $2.50 magazine

Answers

multiply 0.08 times 2.50 you'll get $0.2 twenty cents
2.50X.08=.2
tax is 20 cents 

8 percent =.08 as a decimal. to get the decimal of a percent pretend 8 percent is an 8 with an invisible decimal point at its right. so 8% is 8.0. to get a decimal of a percent, move the point two times to the left, and you will put in a 0 for the blank. so its ._8, where he blank is 0 and so 8%=.08

What is 1 and 1/2 minus 7/8

Answers

Convert 1 and 1/2 to eights to make it easier to subtract. 1 4/8 add 1 to 4/8
12/8 then subtract that by 7/8 straight across the numerator. That then equals 5/8
You would find a common denominator 8. 1 and1/2 would be converted into 1 and4/8. 1 and 4/8 minus 7/8 equals 5/8
