If a/b = 2 /5, b/c = 3 /8, a/c =??​

Answers

Answer 1
Answer:

Answer:

3/20

Step-by-step explanation:

By question it's given that ,

\implies (a)/(b)=(2)/(5)

\implies (b)/(c)=(3)/(8)

And we need to find out the value of a/c .For that Multiply both of them , we have ;

\implies (a)/(b) *(b)/(c)=(2)/(5)* (3)/(8) \n\n\implies (a)/(c)= (3)/(20)

Hence therequired answer is3/20.

Find the values of the variables and the measures of the angles

Answers

Answer:

Add each given variable

(6x + 10) + (x + 2) + x = 8x + 12

The sum of all the angles equals 180ᴼ

8x + 12 = 180

Subtract 12 from both sides

8x = 168

Divide by 8 on both sides

x = 21

Now plug in 21 for each x to find the measure of each angle.

(6[21] + 10) = 126 + 10 = 136ᴼ

(21 + 2) = 23ᴼ

x = 21ᴼ

What is the area

Answers

Final answer:

The area of the rectangle is found by multiplying the length and the width together, giving the polynomial 21x^4 + 56x^3 + 49x^2.

Explanation:

The area of a rectangle can be found by multiplying the length by the height. In this case, the height of the rectangle is 7x^2 and the width of the rectangle is 3x^2 + 8x + 7

So, we multiply these two expressions together to get the area:

Area = 7x^2 * (3x^2 + 8x + 7) = 21x^4 + 56x^3 + 49x^2.

This is a polynomial and it is in standard form, as the terms are ordered from highest degree to lowest degree.

Step-by-step explanation:

From the question, Paloma added a garden to her painting. She has 12 rows of flowers and each row has 13 plants in it while each plant has 15 flowers on it. To calculate the number of flowers in Palomas garden, we multiply the number of rows by the total number of plants and the number of flowers in each plant. This will be:

= 12 × 13 × 15

= 2340 flowers

As Jupiter revolves around the sun, it travels at a speed of approximately 8 miles per second. Convert this speed to miles per minute. At this speed, how many miles will Jupiter travel in 4 minutes? Do not round your answers.

Answers

Jupiter travels at 480 miles per minute and in 4 minutes, it will travel 1920 miles.

What is speed?

Speed is defined as the ratio of the time distance travelled by the body to the time taken by the body to cover the distance.

First to convert it you need to multiply 8 miles per second by 60 seconds because there are 60 seconds in a minute:

8 miles    x    60 s

1 second        1 min

The unit of seconds will cancel out so you will get 480 miles/ min

To get how far it travels in 4 min you need to multiply the speed by 4 minutes

480 miles   x  4 min

  1 min

The unit of minutes will cancel out to get 1920 miles

Therefore, Jupiter travels at 480 miles per minute and in 4 minutes, it will travel 1920 miles.
