Answer:

a) Destiny can run 1 mile is 6 minutes.

b) Destiny can walk back 1 mile is 16 minutes.

Step-by-step explanation:

The running rate of Destiny is

(\frac{1}{8}) \textrm{mile in} (\frac{3}{4}) \textrm{minutes}

So, she runs 1 mile in 8 \times (\frac{3}{4} )\textrm{minutes}  

= 6 minutes

Hence, Destiny can run 1 mile is 6 minutes.

The walking rate of Destiny is

(\frac{1}{4}) \textrm{mile in} 4  \textrm{minutes}

So, she walks 1 mile in 4 \times (4 )\textrm{minutes}  

= 16 minutes

Hence, Destiny can walk back 1 mile is 16 minutes.

Answer:

700,000

Step-by-step explanation:

To explain this, we need to know the basics.

If you look at the number 790,390, you should automatically know that you can also write the same number as:

700,000 + 90,000 + 300 + 90

How did we do this?

Because each number in 790,390 has a <u>value.</u>

In fact, we can do this for any number! Like this:

12,345

You can also write the same number like this:

10,000 + 2,000 + 300 + 40 + 5

Back to the original question. If there is a seven in the hundred thousands place, that means that the 9 is equal to 700,000

Examples:

12,345

The 3 in this number stands for 300, since it is in the hundreds place.

678,900

The 7 in this number stands for 70,000 because it is in the ten thousands place

Now you know!

PolarNik [594]
I=PRT
R=percetnt in decimal form
x%=x/100

I=320
T=2
P=4000
320=(4000)(x/100)(2)
320=8000(x/100)
320=80x
divide both sides by 80
4=x
answer is 4%

What is the probability that a point chosen at random in the given figure will be inside the larger triangle and outside the sma
Anna007 [38]
Given:
Area of a triangle = (h*b) / 2

Area of smaller triangle = (4cm * 4cm) / 2 = 16cm² / 2 = 8 cm²
Area of larger triangle = (6cm * 10cm) / 2 = 60cm² / 2 = 30 cm²

30cm² - 8cm² = 22cm²

Probability that the point is inside the large triangle but outside the small triangle:

22cm² / 30cm² → 11/15 → 0.73 or 73%
