Answer:

\frac{3}{24}=\frac{1}{8}

Step-by-step explanation:

To get the answer we divide \frac{1}{6} by 4 to get the common fraction of \frac{1}{24}. Finally we multiply \frac{1}{24} by 3 to get the answer: \frac{3}{24}.

A floor mat for gymnastics is a square with a side length of 14m. What is the area of the floor mat in square metres? Explain?
TEA [102]

Answer:

196 square meters

Step-by-step explanation:

If the floor mat is square and one side is 14m then all sides are 14m. Given this you would find area by multiplying length by width.

L=14 W=14

14x14=196

There are 196 square meters

Box of T-shirtsAn empty shipping box weighs 250 grams. The box is then filled with T-shirts. Each T-shirt weighs 132.5 grams.The
butalik [34]

1. Name two possible solutions to the equation W = 250 + 132.5T. What do the solutions mean in this situation?

As you can see the weight of the box is given by:

W = 250 + 132.5T

So using this equation we can find the total weight given x number of t-shirts, for example: Suppose we want to know the total weight if the number of t-shirts is 50:

T= 50:

W = 250 + 132.5(50) = 250 + 6625 = 6875g

In the same way if we know the weight, we can determine the total number of t-shirts, for example, suppose the total weight is 5000g:

5000 = 250 + 132.5T

Let's solve for T:

Subtract 250 from both sides:

5000-250 = 132.5T

4750 = 132.5T

Divide both sides by 132.5:

4750/132.5 = T

38.849 = T

so we can conclude that there were approximately 39 t-shirts

6. Consider the equation 2,900 = 250 + 132.50T. In this situation, what is the solution to the equation and what does the solution tell us?

Basically they are telling us that the weight of the box in this case is 2900:

W = 2900

2900 = 250 + 132.5T

So, we can find the total number of t-shirts in the box solving the equation for T:

Subtract 250 from both sides:

2900 - 250 = 132.5T

2650 = 132.5T

Divide both sides by 132.5:

2650/132.5 = T

20 = T

T = 20

This solution tell us that there were 20 t-shirts in the box

0/1 Solve the equation by completing the square. Round your answer to the nearest hundredth, if necessary x^2+18x=7
11111nata11111 [884]

Answer:

The solution to the equation is x = 0.38 or -18.38

Step-by-step explanation:

x^2+18x=7 can be properly written as

x^{2} +18x =7

To solve by completing the square, divide the coefficient of x by 2, square and then add to both sides

i.e 18/2 = 9

Then add 9² to both sides of the equation

x^{2} +18x + 9^{2} = 7 + 9^{2}

This becomes

(x+9)^{2} = 7 + 81

(x+9)^{2} = 88

x+9 = \pm \sqrt{88}

x = -9 \pm\sqrt{88}

x = -9 \pm 9.38

∴ x = -9+9.38 or -9-9.38

x = 0.38 or -18.38

Hence, x = 0.38 or -18.38
