Answer:

The length of the ribbons in all were 25.3 meters.

Step-by-step explanation:

Given:

Lengths of the three pieces of ribbon were 10 meters and 9 decimeters, 3 meters and 10 decimeters, and finally 10 meters and 4 decimeters.

Now, to find the length of the ribbons in all.

So, by adding the length of all three pieces we get the length of all the ribbons:

10 meters\ 9 decimeters

+3 meters\ 10 decimeters

+10 meters\ 4 decimeters.

=23 meters\ \ 23\ decimeters.

Now, converting the decimeters into meters = 23 meters + 2.3 meters = 25.3 meters.

(1 decimeter = 0.10 meter)

(23 decimeter = 2.3 meter.)

Therefore, the length of the ribbons in all were 25.3 metres.

guajiro [1.7K]

Answer:

9,772,219 (Approx)

Step-by-step explanation:

Given:

Current population = 8,851,000

Growth rate = 2% = 0.02

a. Time = t

b. Time = 5 years

Find:

a. Write the equation.

b. Population after 5 year = ?

Computation:

a. Equation for the following question:

After population = Current\ population(1+r)^n

After\ population =8,851,000(1+0.02)^t\\\\After\ population =8,851,000(1.02)^t

b. Population after 5 year

=8,851,000(1.02)^5\\\\=9,772,219.16

Find three consecutive even integers. Such that 7 times of first integer is 4 more than the sum of second and third integers
attashe74 [19]

Answer:

1st even integer = 2

2nd even integer = 4

3rd even integer  = 6

Step-by-step explanation:

Let the consecutive even integers be:

1st = 2(x)

2nd= 2(x +1) = 2x + 2

3rd = 2(x + 2) = 2x + 4

According to Given conditions:

7(2x) = 4 +  2x +2 + 2x + 4

By Simplifying:

14x = 10 + 4x

Subtracting 4x from both sides

14x - 4x = 10 + 4x -4x

10x = 10

Dividing both sides by 10 we get:

x = 1

Now putting value of x in supposed integers:

1st even integer = 2(1) = 2

2nd even integer = 2(1)+2 = 4

3rd even integer = 2(1) + 4 = 6

I hope it will help you!

How do I find what x equals
Jobisdone [24]

Answer:

basically, you get x to one side and the number to another side, then simplify. For example, 3x-2=x+6. The steps are:

2x-2=6, here we brought the x to the other side by subtracting an x from each side. Since the x was positive (adding) we subtract x from each side.

2x=8, we did the same thing but added 2 to each side since -2+2=0, and now it is on the other side.

x=4, 2x means x times 2, so you would divide each side by 2.

In short, put x on one side and number on the other by doing the opposite of what something says, remove multiplication or division by doing the opposite. You must always do it on both sides, or it is not an equation.

A packet contains blue and yellow flower seeds in thwle ratio 3:4. there are 32 floweer seeds​
Sliva [168]

Note: We need to find the number of seeds of each color.

Given:

A packet contains blue and yellow flower seeds in the ratio 3:4.

There are 32 flower seeds​.

To find:

The number of blue and yellow flower seeds.

Solution:

Let the number of blue and yellow flower seeds are 3x and 4x respectively.

There are 32 flower seeds​.

3x+4x=32

7x=32

x=\dfrac{32}{7}

x\approx 4.57

Now,

The number of blue flower seeds is

3(4.57)=13.71\approx 14

The number of yellow flower seeds is

4(4.57)=18.28\approx 18

We approx. the value rounded to the nearest integer because the number of flower seeds cannot be a decimal of fractional value.

Therefore, the number of blue seeds is 14 and the number of yellow seeds is 18.
