An office building casts a 90 foot shadow. At the same time of day, a 5 foot woman standing near the building casts an 8 foot shadow. What is the approximate height of the building to the nearest foot?A) 40 feet
B) 49 feet
Eliminate
C) 56 feet
D) 63 feet

Answers

Answer 1
Answer: I think it would be C) 56 feet. See, if we take the height of the woman(5) over the shadow she casts(8), and crossmultipy it with the height of the building(?) over the shadow of the building(90), it would be approximately 56 feet.       5/8  ?/90      90x5= 450 450/8= 56.25

1)What is the exact circumference of a circle with a radius of 15 cm?

The circumference of a circle is calculated by the equation:

C  = 2πr = 2π(15 cm) = 30π cm

2)What is the exact circumference of a circle with a radius of 16?

The circumference of a circle is calculated by the equation:

C  = 2πr = 2π(16 cm) = 32π cm

Answer:

The answer is 30

Step-by-step explanation:

I took the quiz. In order to find the circumference, you will need to multiply your number by 2. In this case, your answer will be 30^^

twelve and three tenths more than five and thirteen thousandths of a number d is equal to fifteen and three hundred two thousandths. what is the value of d?

Answers

12 3/10 (12 3/10) more than (+) 5 13/1000 of a number d (5 13/1000d) is equal to (=) 15 and 302/1000 so


we want the bottom numbers the same so

12 and 3/10=12 and 300/1000
5 and 13/1000 is the same
302/1000 is the same so

12 300/1000+5 13/1000d=15 302/1000
subtract 12 300/1000 from both sides
5 13/1000d=3 2/1000
5 13/1000d=5013/1000d
3 2/1000=3002/1000
5013/1000(d)=3002/1000
multiply both sides by 1000/5013 (to make it a one exg 1/2 times 2/1=2/2=1)

d=3002/5013 times 1000/1000=3002/5013≈0.59843

F(x)=-2x+3 how do you find x if f(x) = 11

Answers

since we know f(x)=11 all we need to do is substitute and solve. so
11=-2x+3 subtract 3 from both sides
8=-2x divide both sides by -2
-4=x
sub back in to check

-2(-4)+3=8+3=11 looks good
