Step-by-step explanation:

Two friends leave school at the same time, Sarah is heading due north and Beth is heading due east. One hour later they are 10 miles apart. If Sarah had traveled 8 miles from the school, how many miles had Beth traveled?

Answers

Answer: 6 miles

Step-by-step explanation:

If you picture this scene in your head, you will get a simple 3x4x5 right triangle. 4 times 2 is 8, 5 times 2 is 10, so Sarah should, by now, have traveled 3 times 2 miles.

Final answer: Beth has traveled 6 miles after an hour.

Hope this helped! :)

Helping tip: The reason it is not 4 is because they are not traveling west and east away from each other. They are traveling north and east, so they are moving in two directions to form a right triangle, and the hypotenuse would be 10 (miles). The side, or distance, that Beth has traveled is 8. So as this is a typical variation of a 3x4x5 triangle Beth will have traveled  6 miles.

Solve: 2x-5/3 + 3/5 = 0​

Answers

Answer:

The value of x is 8/5.

Step-by-step explanation:

Solution :-

[tex]\sf \leadsto \dfrac{2x - 5}{3} + \dfrac{3}{5} = 0[/tex]

[tex]\sf \leadsto \dfrac{10x - 25 + 9}{15} = 0[/tex]

[tex]\sf \leadsto \dfrac{10x - 16}{15} = 0[/tex]

[tex]\sf \leadsto 10x - 16 = 0[/tex]

[tex]\sf \leadsto 10x = 0 + 16[/tex]

[tex]\sf \leadsto 10x = 16[/tex]

[tex]\sf \leadsto x = \dfrac{16}{10}[/tex]

[tex]\sf \leadsto x = \dfrac{8}{5}[/tex]

Answer:

x = 1 3/5 or 8/5

Step-by-step explanation:

What is the value of w in the equation
0.04w + 0.6= 2.4?

Answers

Answer: 45

Step-by-step explanation:

0.04w+0.6=2.4

Step 1: Subtract 0.6 from both sides.

0.04w+0.6−0.6=2.4−0.6

0.04w=1.8

w=45

Answer:

w = 45

Step-by-step explanation:

What is the value of w in the equation

0.04w + 0.6= 2.4?

0.04w + 0.6 = 2.4

0.04w = 2.4 - 0.6

0.04w = 1.8

w = 1.8 : 0.04

w = 45

-----------------------------

check

0.04 × 45 + 0.6 = 2.4

1.8 + 0.6 = 2.4

2.4 = 2.4

The answer is good

Answers

Answer:

[tex]21\frac{3}{4}[/tex]

Step-by-step explanation:

Step 1: Add the numbers.

20.25 can also be expressed as [tex]20\frac{1}{4}[/tex], because [tex]\frac{2025}{100}[/tex] = [tex]\frac{81}{4}[/tex] = [tex]20\frac{1}{4}[/tex]. So if we add [tex]20\frac{1}{4}[/tex] and 11, we would get [tex]31\frac{1}{4}[/tex]

Step 2: Solve

[tex]31\frac{1}{4} -9\frac{1}{2}[/tex]

Subtract the whole numbers

[tex]31-9=21[/tex]

Combine the fractions

This means addition. Also, since our denominators are not the same value, we have to find the LCM (Least Common Denominator): What do 2 and 4 have in common that they can divide themselves by? 4. We know this because 2 divided by 4 is 2, and 4 divided by 4 is 1, so they can both divide themselves by 4.

[tex]\frac{5}{4}-\frac{1}{2}[/tex]

LCM

[tex]\frac{5}{4}-\frac{2}{4} =\frac{3}{4}[/tex]

Therefore, the simplified expression to this is [tex]21\frac{3}{4}[/tex].

PLEASE HELP ME IT WILL MEAN A LOT TO ME .

Answers

Answer:

19%

Step-by-step explanation:

Use a common measurement style. Generally, it is easiest to use decimal.

0.22 is given as a decimal.

19% means 19/100, in which, when changed to a decimal, you will move the decimal point to the left two place values, giving you the value of 0.19

For fractions, you will generally set it over 100 first, before finding the decimal. Remember that what you multiply to the denominator you must multiply to the numerator:

1/5 x (20/20) = 20/100

20/100 = 0.20

19% is the one that contains the least amount of calories from fat.

~

The first thing we need to do is convert all of the to the same unit: fractions, decimals, or percentages. So 1/5 is 0.20 and 19% is .19 so we have 0.20, 0.22, and 0.19
We do. least to greatest: 0.19, 0.20, 0.22 which is. 19%, 1/5, .22
