The local newspaper has letters to the editor from 40 people. If this number represents 4% of all of

Setler79 [48]

Answer:

1000 readers

Step-by-step explanation:

40 people represent 4% of the total number of readers.

4% is 1/25 of 100%, therefore:

4% x 25 = 100%

So, if we multiply the number of people that represent 4% by 25, we will get the total number (100%).

40 x 25 = 1,000

The newspaper has 1000 total readers.

Alternatively, you could also divide 4% (40) by 4 which would give you 1%=10. Multiply this by 100 to get 100% which gives us: 100% = 1000.

Hope this helped!

HELP ME PLEASE, I'D LIKE TO UNDERSTAND HOW TO DO THIS TOO SO I'LL GIVE BRAINLY FOR THE RIGHT ANSWER WITH GOOD AND UNDERSTANDING

Answer:

34 goes in the blank.

Step-by-step explanation:

Triangle ABC is congruent to triangle TUV implies the following:

Angle A is congruent to angle T.

Angle B is congruent to angle U.

Angle C is congruent to angle V.

Side AB is congruent to side TU.

Side BC is congruent to side UV.

Side CA is congruent to side VT.

Note: Order tells you everything in a congruence statement.

Since side BC is congruent to UV, then the measure of side BC is equal to the measure of side UV.

8x+2=7x+6

Subtract 7x on both sides:

1x+2=6

x+2=6

Subtract 2 on both sides:

x=6-2

x=4

So if x=4, then the measure of side BC is 8x+2=8(4)+2=32+2=34.

So the measure of BC is 34 cm.

3√6+4√6 is equal to

Oksi-84 [34.3K]

Answer:

$7\sqrt{6}$

Step-by-step explanation:

You can only add radicals if the value inside the square root symbol is the exact same, therefore, this one is 6. To find the sum, we can add the values outside the square root symbol (3 and 4) to get our new radical.

We can also check this.

$3\sqrt{6} = \sqrt{9*6} = \sqrt{54}$ ≈ 7.35

$4\sqrt{6} = \sqrt{16*6} = \sqrt{96}$ ≈ 9.8

$7\sqrt{6} = \sqrt{49*6} = \sqrt{294}$ ≈ 17.15

7.35+9.8 = 17.15

Hope this helped!
