Answers

Answer 1

Answer:

22.5 miles per hour (rounded answer)

Step-by-step explanation:

This is a fraction equal to

18 miles ÷ 0.8 hours

We want a unit rate where

1 is in the denominator,

so we divide top and bottom by 0.8

18 miles ÷ 0.8

0.8 hours ÷ 0.8

22.5 miles

1 hour

22.5 miles

hour

= 22.5 miles per hour

Answer 2

A surveyor has poles A, B, and C set to form a right triangle with the right angle at B. If the distance from A to B is 35 meters and the distance from B to C is 25 meters, what is the distance from A to C? He can t measure it because there is a deep pond between points A and C.

Answers

It's about Pythagorean theorem.

AB*AB + BC*BC = AC*AC, so:

35*35 + 25*25 = AC*AC
1225 + 625 = AC*AC
1850 = AC*AC

So AC is a root of 1850, which is ~43 (exactly: 43,01162633521313)

It means that distance between A and C is 43 meters and some milimeters.

Your bank balance is $102.35 and you've just made purchases for $20, $33.33, and $52.80. You then make deposits of $25 and $24.75. What's your new balance?

Answers

Answer:

The new balance is $45.97 .

Step-by-step explanation:

As given

Your bank balance is $102.35 and you've just made purchases for $20, $33.33, and $52.80.

Bank balance after the purchase = $102.35 - $20 -$33.33 - $52.80

= $102.35 - $ 106.13

= - $3.78

As given

You then make deposits of $25 and $24.75.

Total deposit money = $25 + $24.75

= $49.75

Thus

New balance = Bank balance after the purchase + Total deposit money

= - $3.78 + $49.75

= $ 45.97

Therefore the new balance is $45.97 .

$102.35 - $20 = $82.35
$82.35 - $33.33 = $49.02
$49.02 - $52.80 = $-3.78
$-3.78 + $25 = $21.22
$21.22 + $24.74 = $45.97
so $45.97 is your answer

Yosai is making a kimono for her father, The belt for the kimono should be one hundred sixty-three centimeters long. She has two meters of fabric. How much fabric will she have left after making the belt? (State your answer in meters.)

Answers

Answer:

Amount of fabric left = 0.37m

Step-by-step explanation:

Yosai has 2 meters of fabric, and the belt for the kimono should be 163 centimeters long.

In order to find out how much fabric she will have left after making the belt, we need to calculate the length of fabric used for the belt and then subtract that from the total amount of fabric.

$\sf 1 meter = 100 centimeters$

So, the length of fabric needed for the belt is:

$\sf 163 \, \text{cm} = (163)/(100) \, \text{m} = 1.63 \, \text{m}$

Now, subtract the length of fabric used for the belt from the total amount of fabric:

$\begin{aligned} \textsf{ Remaining fabric } &\sf = \textsf{ = Total fabric - Fabric used for the belt }\n&\sf = 2 m - 1.63 m\n&\sf \approx 0.37 m \end{aligned}$

So, Yosai will have approximately 0.37 meters of fabric left after making the belt for the kimono.
