The values of w is inversely proportional to m .If w=8 then m=25; what is m when w=20? Show me the steps please

Answers

Answer:

m = 10

Step-by-step explanation:

The values of w is inversely proportional to m

Mathematically:

w ∝ 1/m

w = k × 1/m

w = k/m

Where k is the Constant of Proportionality

Step 1

Solve for k

If w=8 then m=25

w = k/m

8 = k/25

Cross Multiply

k = 25 × 8

k = 200

Step 2

what is m when w=20? Show me the steps please

We solve for m

w = k/m

k = 200

20 = 200/m

Cross Multiply

20m = 200

m = 200/20

m = 10

Answer:

3. - 8n² -8n + 3

Step-by-step explanation:

(4n^4 - 8n +4) - (8n² + 4n^4 +1)

Firstly, open the brackets.

= 4n^4 - 8n +4 - 8n² -  4n^4 - 1

Now, group like terms.

= 4n^4 - 4n^4 - 8n² -8n - 1 + 4

4n^4 - 4n^4 cancel out with each other since one is negative and the other is positive. So we're left with - 8n² -8n - 1 + 4

= - 8n² -8n - 1 + 4

= - 8n² -8n + 3

4. AC = 36

5. m<UTW = 42

Step-by-step explanation:

4.

AB = BC

-x + 25 = 3(2x - 8)

-x + 25 = 6x - 24

-7x = -49

x = 7

AC = 2(-x + 25) = 2(-7 + 25) = 2(18) = 36

AC = 36

then you find the area of the rectangle

After than you try to find the triangles area

the bottom of the triangle is 9m but since to split it in 2 you will now have 7m

multiple 5 times 7 and you will receive 35 then you divide that by 2 and you will have 17.5m^2

Step-by-step explanation:

have a wonderful day! brainliest?

Answer:

B. (7)

Step-by-step explanation:

First, we figure out how many more items Joshua needs to sell so we do 20 - 6.

20 - 6 = 14.

Next, we do 14 / 2 because each customer buys 2 items.

14 / 2 = 7

Therefore, Joshua must have 7 additional customers to reach his goal.

Look at the picture. Are the triangles similar? If so, choose the answer that explains why.

Answers

Answer:

yes. by AAA, i think she mistyped an A not sure

Step-by-step explanation:

The remaining angle of the bigger triangle = 180 - 84.6 - 30.4 = 65 (angle sum of triangle)

The three angles are the same for both triangles

The triangles are similar to each other because the angle-angle theorem is satisfied.

What is the triangle?

A triangle is a three-sided polygon with three angles. The angles of the triangle add up to 180 degrees.

The triangles are given.

Let the third angle of the triangle be x. Then we have

84.6° + 30.4° + x = 180

                        x = 65°

Then the triangles are similar to each other because the angle-angle theorem is satisfied.

Thus, the correct option is C.

Simplify 5/15: the numerator and denominator are both multiples of 5, so the fraction can be reduced to 1/3 by dividing the top & bottom by 5. 5/15 of a rectangle is the same as 1/3 of a rectangle.

Compare 1/2 and 5/7:
The simplest way is to ask if 5/7 is more than one half. Half of 7 is 3.5, and 5 is greater than 3.5, so 1/2 < 5/7.
The way that is a little more work is to get a common denominator and make equivalent fractions of 7/14 and 10/14.

Fraction to decimal of 4/5. 4 divided by 5 = 0.8

Decimal to fraction, 0.78:
0.78 = 78 hundredths = 78/100 as a fraction. They usually want fractions in the lowest terms, so divide the numerator and denominator by two, and you have 39/50.

Mixed to improper fraction 5 2/9: multiply the denominator of 9 times the whole number of 5, that equals 45. Add the 2 in the numerator, that is 47. Keep that over 9, because we are trying to figure out how many ninths we have. 5 2/9 = 47/9

Add ‘em 3/5 + 1/2:
Make equivalent fractions with a common denominator. (10 is the least/lowest common denominator). So we are adding 6/10 + 5/10 = 11/10 or 1 1/10.

Improper to mixed, 9/4:
We have 9 fourths. 4 fourths = 1 whole. So we get 2 wholes with 1/4 left over. 9/4 = 2 1/4.

Subtract ‘em, 3/10 - 1/5.
Again, need a common denominator/equivalent fraction. 1/5 = 2/10
3/10 - 2/10 = 1/10

Draw it, 1/3:
The circle is already divided into thirds. Shade one of them in.

Multiply ‘em 2/3 x 5:
Multiply the numerator times the whole number, leave the denominator alone. 2/3 x 5 = 10/3 = 3 1/3 if they want it converted to a mixed number.

Divide ‘em: 8/9 divided by 3 is 8/27

What’s the word?
4 x 1/2 = 2 (what is one half of 4?)

Word up:
3/5 divided by 3 = 1/5
