What is 15% of 15% of 15% of 500 how does this compare to finding 45% of 500

2 answers:

"500* (15/100)* (15/100)* (15/100)= 1.6875

500* (45/100)= 225

Therefore, the process of finding 45% of 500 does not have anything to do with the process of finding 15% of 155 of 15% of 500~"

15% of 500 is 75, 15% of 75 is 11.25, 15% of 11.25 is 1.6875, an 45% of 500 is 225. Does that help?

Coach Chapman has 54 students signed up for a jump rope competition. He only has 18 jump ropes. What is the ratio of jump ropes

Andrei [34K]

Answer:

1:3

Step-by-step explanation:

The question is asking what the ratio of jump ropes to students is.

The order of the question matters.

Since they ask for the jump ropes first and then the students, we

get a ratio of 18:54.

Find the GCF (Greatest Common Factor)

The GCF is 18.

Divide 18:54 by 18.

18/18=1

54/18=3

The answer is 1:3.

Find the value of c, rounded to the nearest tenth A. 11 B. 14.3 C. 37.6 D. 7.4

Helga [31]

Answer:

D. The correct value of c = 7.4

Step-by-step explanation:

According to Tangent-Secant theorem:

"When a tangent and a secant are drawn from one single external point to a circle, square of the length of tangent segment must be equal to the product of lengths of whole secant segment and the exterior portion of secant segment."

Here, the external length of tangent segment = 10

Also, the length of internal segment is 14 and c.

So, by the SECANT THEOREM:

$(10)^2 = 14 \times c\\\implies c = \frac{100}{14} = 7.14$

or, c = 7. 1428

Now, rounding off the value of c = 7. 14 to the nearest tenth, we get

c = 7. 4

Hence the correct value of c = 7.4

Can someone help I’m not good with word problems

pickupchik [31]

Answer:

I agree that this question can be confusing:

Apparently point A and point B must be on the same straight line (measured from the light house or the question would be nonsensical)

tan 13 = H / DA where H is height of lighthouse

tan 8 = H / DB tangent measured from point B

tan 13 / tan 8 = DB / DA

DB = .2309 / .1405 * 1279 = 2101 ft

DB - DA = 2101 - 1279 = 822.0 ft
