Mathematics
1 answer:
Ksju [112]3 years ago
3 0

Answer:

[See Below]

Step-by-step explanation:

✦ So when we see x^{2}, these are powers or exponents.

  ✧ We solve them like this:

  • 7^{2}= 7*7
  • 7*7=49

✦ So the answers would be:

  • 5^{2}=25
  • (-16)^{-2} =-0.00390625
  • \frac{1}{8^{2} }=0.015625

An ant moves 18 millimeters every 5 seconds
vaieri [72.5K]

Answer:

Step-by-step explanation:

First we need to find their rate of speed.

r = d / t

For ant,

Convert millimeters to inches.

1 inch = 25.4 mm

18 mm = 0.7 inch

r = 0.7 / 5

r = 0.14 inches per second

For beetle,

r = 8 / 3

r = 2.7 inches per second

From the rates, you can tell that the beetle crosses the Garden first.

To know how long it takes for the ant to cross is by dividing the length by the rate.

1 yard = 36 inches

13 yards = 468 inches

468 ÷ 0.14 = 668.5 ≈ 669 seconds

In terms of minutes:

11 minutes and 15 seconds

The ant would cross the garden in 11 minutes and 15 seconds (or 669 seconds <em>up to you</em>).

The scatter plot shows the study times and test scores for a number of students. How long did the person who scored 81 study?
Free_Kalibri [48]

Answer: Option A

50 minutes

Step-by-step explanation:

Observe in the diagram that the vertical axis represents the score obtained and the horizontal axis represents the study time.

To find out how many hours the person with a score of 81 studied, locate the point that is at a vertical distance of 81.

Now draw a vertical line from this point to the horizontal axis. Note that the vertical line traced intercepts the vertical axis at x= 50

Then the person who got a score of 81 studied 50 minutes

The answer is the option A
