7 times as much as sum of 1/3 and 4/5

Answers

Answer 1
Answer: So the formula is
7*(1/3+1/5) = x

First find the common denominator of the fractions.  In this case the common denominator of 3 and 5 is 15 so we must convert them to 15ths.  To do that we divide 15 by the denominator and take that answer and multiply the numerator by it.

So for 1/3 we take 15/3(denominator) = 5 and multiply the numerator (1) by it

5 * 1 = 5 so 1/3 converts to 5/15

Do the same for 1/5 we take 15/5 = 3 and multiply the numerator (4) by it

3*4 = 12 so 4/5 converts to 12/15

Now we add 5/15 and 12/15 = 17/15 so we have our formula now to

7*17/15

We make seven a fraction 7/1 and multiply across 7*17 = 119 and 15 * 1 = 15

We have 119/15 which when we divide and get 7 14/15 as your answer
Answer 2
Answer: find a common denominator aka 15
so 5/15 and 12/15
= 17/15 times 7/1
119/15

A plane at an altitude of 20000 feet starts to descend for landing after flying for six hours. The entire flight time was 6 hours 40 minutes. Determine the average rate of descent of the plane

Answers

Check the picture below.

so, let's see, the plane departs from (0, 0), the origin, goes up to 20000 feet, sticks around flying for 6 hours, 6hrs = 3600 minutes, (6*60).

so the plane's descent starts off at the point (3600, 20000) down to (3640, 0) as you see in the picture, keeping in mind that average rate of change = slope.

\bf (\stackrel{x_1}{3600}~,~\stackrel{y_1}{20000})\qquad (\stackrel{x_2}{3640}~,~\stackrel{y_2}{0}) \n\n\n slope = m\implies \cfrac{\stackrel{rise}{ y_2- y_1}}{\stackrel{run}{ x_2- x_1}}\implies \cfrac{0-20000}{3640-3600}\implies \cfrac{-20000}{40} \n\n\n \cfrac{-5000}{1}\cfrac{ft}{minute}\implies -5000(ft)/(min)

the slope is negative, since it's a descent, the plane is coming down, not going up over the minutes axis.

Answer: 500 feet per minute

Step-by-step explanation:

Landing time 40min with an altitude of 20000 remaining

40=20000 | both sides /40

1=500

Answers

The answer is A, because:
The dimentions in cm are 5cm by 3cm, so you make that to scale. The page says that 1cm is equal to 5m, so you multiply both numbers by 5 and you get 25 by 15. If you need clarification, let me know.
The answer is a because to get the length of the sides you do 7-4 which is 3 times five is 15m. To find the base you do 2 times 3 times 5 which is 25m. A) 25m. * 5m.

1) Which of the following shows the correct steps to find the value of 27 1/3?A) 27 1/3=(9^3)1/3=(9)^3(1/3)=9
B) 27 1/3=(3^9)^1/3=(3)^9(1/3)=3
C) 27 1/3=(3^4)1/2=(3)^4(1/2)=9
D) 27 1/3=(3^3)^1/3=(3)^3(1/3)=3

Answers

First of all, we need to know: 3^3 = 3 x 3 x 3 = 9 x 3 = 27

So:

(27)^{(1)/(3)} = (3^3)^{(1)/(3)} = (3)^{3* (1)/(3)} = 3^(1) = 3

So, your answer is D.

1,148 people

Answers

924 people rode the rollercoaster.

The answer is option (C).

What is a percentage?

The percentage means the required value out of 100.

It is calculated by dividing the required value by the total value and multiplying by 100.

The percentagechange is also calculated using the same method.

In percentage change, we find the difference between the values given.

Example:

Required percentage value = a

total value = b

Percentage = a/b x 100

We have,

To find the number of people who rode the roller coaster,

We can multiply the total number of people at the park by the percentage who rode the roller coaster:

So,

The number of people who rode the roller coaster.

= 77% × 1,200

= 77/100 x 1200

= 924

Therefore,

924 people rode the rollercoaster.
