Hello!

Since we know how much they walked in 4/9 of an hour, we will divide 4/5 by 4/9 to get 4/9 to one.

$\frac{4}{5}$ ÷ $\frac{4}{9}$ = $\frac{36}{20} = \frac{9}{5}$

They went 1 4/5 mph or 1.8 mph.

I hope this helps!

The distance between B and C

alina1380 [7]

Answer:

The answer is

<h2> $\sqrt{13} \: \: or \: \: 3.6055 \: \: units$ </h2>

Step-by-step explanation:

The distance between two points can be found by using the formula

$d = \sqrt{( {x1 - x2})^{2} + ({y1 - y2})^{2} } \\$

where

(x1 , y1) and (x2 , y2) are the points

From the question the points are

B ( 3 , 1 ) and C( 6 , 3)

The distance between them is

$|BC| = \sqrt{( {3 - 6})^{2} + ({1 - 3})^{2} } \\ = \sqrt{ ({ - 3})^{2} + ( { - 2})^{2} } \\ = \sqrt{9 + 4}$

We have the final answer as

$\sqrt{13} \: \: or \: \: 3.6055 \: \: units$

Hope this helps you

1. HELP Use front-end estimation to estimate the sum 8.86 + 9.43 + 5.75

marta [7]

Answer:

1. Option D.

2. Option A.

Step-by-step explanation:

1. You need to follow these steps in order to estimate the sum of $8.86 + 9.43 + 5.75$ :

Step 1: Add the digits in the ones places of the whole numbers (these are: 8, 9 and 5).

Step 2: Round the decimals to the nearest whole number:

$0.86\approx 1\\\\0.43\approx0\\\\0.75\approx1$

Step 3: Add them together:

$8+9+5+1+0+1=8+9+5+2=24$

2. The procedure to estimate the difference of $83.92-47.23$ is:

$83.92-\\47.23\\........\\40.00\\\ -4.00\\\ \ + 0.70\\-0.01\\...........\\+36.00\\+0\ 0.69\\..............\\36.69$

Rounded to the nearest whole number:

$36.69\approx 37$
