There are a total of 100 balloons. If the ratio of yellow balloons to blue balloons is 8 to 12, how many of them are yellow

Answers

If you have 8 yellow balloons for every 12 blue balloons, then if you have 20 balloons in total, 8 out of 20 of those balloons will be yellow. Then you can set up this ratio:

$(8yellow)/(20total) = (Xyellow)/(100total)$

Then, you can use either cross multiplication or multiply the numerator and denominator by the same number to help solve for x. Personally, I prefer cross multiplication, so that's what I'll show you here:

$(8yellow)/(20total) = (Xyellow)/(100total) \n 8yellow*100total=20total*Xyellow$

Finally, solve for x:

$8yellow*100total=20total*Xyellow \n 8*100=20*x \n 800=20x \n 800/20=20x/20 \n x=40yellow$

If you had 100 balloons, you will have 40 yellow balloons.

14/20 minus 3/5 equals

Answers

$(14)/(20)-(3)/(5)=(14:2)/(20:2)-(3)/(5)=(7)/(10)-(3)/(5)=(7)/(10)-(3\cdot2)/(5\cdot2)=(7)/(10)-(6)/(10)=(7-6)/(10)=(1)/(10)$

$(14)/(20)=(14:2)/(20:2)=(7)/(10)=0.7\n\n(3)/(5)=(3\cdot2)/(5\cdot2)=(6)/(10)=0.6\n\n(14)/(20)-(3)/(5)=0.7-0.6=0.1$

the answer for this question is 0.1

Evaluate the expression 15-(37 8) divided by 3

Answers

the correct question is

Evaluate the expression $15-(37+8)$ divided by $3$

we have

$(15-(37+8))/(3) =(15-(45))/(3) \n \n =-(30)/(3) \n \n =-10$

therefore

the answer is

$-10$

15-378=-363
-363÷3 =-121

Solve 3x+2y=5 and x+y=3 as a graph, substitution, or elimination?

Answers

Step-by-step explanation:

multiply second equation by -2

-2 × (x+y) = 3➡ -2x - 2y = -6 now add up both equations

3x + 2y - 2x-2y = 5-6 ➡x = -1 (-2y eliminated +2y)

now use the value we found for x in the second equation to find the value of y

x + y = 3 we found x as -1

-1 +y = 3 ➡y = 4

All chalk line is place around the perimeter of the football field. What is the length of this line in feet? The field is 531/3yd length and 120yd width

Answers

Answer: 1040 feet.

Step-by-step explanation:

We know that , Perimeter of a rectangle = 2 (length +width)

As per given , we have

Length of football ground = $53(1)/(3)\text{yards}=(53*3+1)/(3)\text{yards}=(160)/(3)\text{ yards}$

Width = 120 yards

Since, the football ground is rectangle in shape.

Then , Perimeter of the ground = $2((160)/(3)+120)$ yards

$=2((160+3(120))/(3))$ yards

= $2((160+360)/(3))$ yards

$=2((520)/(3))$ yards

$=(1040)/(3)$ yards

Also, 1 yard =3 feet

i.e. Perimeter = $(1040)/(3)*3=1040$ feet

Hence, the required perimeter is

346 2/3 feet is the length of the line around the perimeter of the field

What number is exactly halfway between 1250 and 1500

Answers

To find the answer we have to find the difference between the two numbers, divide it by 2 then add it back into the original number ... Let me show you.

1500 - 1250 = 250
250 ÷ 2 = 125
1250 + 125 = 1375

1375 is half way between 1250 and 1500

1375 should be the correct answer
