Answer:

8.94427191...

Step-by-step explanation:

21*21 - 19*19 = [tex]x^{2} \\\\[/tex]

441 - 361 = [tex]x^{2}[/tex]

[tex]x^{2}[/tex] = 80

x = 8.94427191...

Answer:

Of course the percentage is an increase. If it moves from 50ft to 190 ft its an increase. So you can automatically cross out “c” and “d”.

Now just think about it logically. This can save you from a lot of work.

So you have it from 50ft to 190 ft.

Use 100% place holders.

50ft*100 percent is 50

50ft*200 percent is 150

Now your somewhere close near the 190 ft range.

THink about the last two options, you can ignore the 200 percent since thats what we used as the closest possible place holder.

Now use 50% place holders.

50% of 50 is 25.

so 175 is the closest we can get with 250%

Now we still have about a 15 ft space.

250% is obviously greater then 238% so we can elimate that option.

The final answer is (B)

Step-by-step explanation:

If wanted proof

So we discussed this logically but if you want it mathematically below is the explanation:

50ft to 190 ft.

To calculate percentage of change you want to first find the distance.

190-50=140

Theres a 140 ft change.

Now you can use proportions

50/1 = 140/x

The 50/1 represents 50 feet for 100 percent or 1

The 140 represents 140 feet for (x) feet since its unknown

now cross multiply

50*x

140*1

50x=140

Now solve

140/50=2.8

2.8 is the deciaml If you convert it to a percentage you just multiply it by a hundred since percent means out of a hundred.

2.8 out of a hundred it 280%

Angle ABD = Angle CBD

or, 9x-7 = 6x+2

or, 9x-6x = 2+7

or, 3x = 9

or, x = 9 ÷ 3

or, x = 3

= Measure of Angle ABD + Measure of Angle CBD

= [(9x-7)+(6x+2)]°

= [(9×3-7)+(6×3+2)]°

= [27-7+18+2]°

= 40°

x = 3

Measure of Angle ABC = 40°.

Hope it helps you.

Answer:

54:78

Step-by-step explanation:

We multiply 9 and 13 to 6

9 × 6 = 54

13 × 6 = 78

54 + 78 = 132

Ratio representation gives the sharing proportion of a number, the numbers expressed in the ratio 9:13 of 132 are 54 and 78 respectively

Given the Parameters :

To obtain each Value, we use the relation ;

For the 9 portion of the ratio :

(9 / (9+ 13)) × 132

(9 / 22) × 132

= 54

For the 13 portion of the ratio :

(13 / (9+ 13)) × 132

(13 / 22) × 132

= 78

Therefore, the two numbers are 54 and 78

Answer:

9/25

Step-by-step explanation:

In this case, 0.36 has two numbers after the decimal, so, we place 100 in the denominator and remove the decimal point.

⇒ 36/100

After reducing this fraction we get

⇒ (36 ÷ 4) / (100 ÷ 4) = 9/25

Answer:

The correct answer for this question is that the unit rate is 5:1. We can work this out by simplifying down the 2 commercials to every 10 songs ration, so that 10:2 becomes 5:1. We can work this out by halving the original ratio to simplify it. Hope This helps.

divide both sides by 6

Step-by-step explanation:

3(2x + 10) = 54 ( distribute the parenthesis by 3 )

6x + 30 = 54 ( subtract 30 from both sides )

6x = 24

The last step is to divide both sides by 6
