If the ratio is 7 to 1, the width of the wing must be 1/7 of the length. So, we just divide 26.7 by 7 to get 3.81 meters.

Catherine 168 pieces of gum playing at a bean bag toss in the county fair at school she gave three to every student in her math
Drupady [299]

Givens

Let the number of students in the class be x

Let the number of pieces of gum she gave out be 3x

Equation

3x + 8 = 168 This will not work out evenly. Let's try x - 1. The reason for that is because she may not give out anything to herself.

3(x - 1) + 8 = 168      This doesn't work either.

Well we have to choose. It's a rounding problem.

3x + 8 = 168     Subtract 8 from both sides.

3x = 168 - 8      Combine

3x = 160           Divide by 3 on both sides.

x = 160 / 3

x = 53.333333333

Since that can't be, we could say there were 53 students.

3x

Wildflower mix contains several different types of seeds.
Sveta_85 [38]
The chance would be 9.52% (rounded) because you would take the total number of seeds (63) and divide the number of poppy seeds by the total.
Then you would convert decimal fraction by multiplying it by 10.

PLSSS HURRY!!!!!!!!
Vikki [24]

Answer:

A) x=5 or -11

Step-by-step explanation:

The given equation is:

(x+3)^2=64

The most suitable method so solve this quadratic equation is the square root method.

We take square root of both sides to obtain:

x+3=\pm \sqrt{64}

\implies x+3=\pm8

\implies x=-3\pm8

We now split the plus or minus sign to get;

x=-3-8\:,x=-3+8

This simplifies to:

x=-11\:,x=5

The correct choice is A
