What graph? We can’t solve if we don’t have a graph.
Answer:
Step-by-step explanation:
First, you have to find the total number of socks. The total is 14. Now, since you choose 2 socks out of 14 in total, the probability is 2/14 or about 14%. To find the percent, just divide the numerator by the denominator. The answer you get is in decimal form. Multiply the decimal by 100. Then, there is your percent.
Since we don't have the measurements for the trapezoid, we can't find the exact cost. However, I can explain how to solve the problem.
First, you need to find the the total area of the pool cover. Since it is in the shape of a trapezoid, use the formula below.
A = 0.5(h)(the sum of the bases)
Once you have the area, multiply by 0.79 and you will have the cost.
Rectangle- multiply it’s height by width
Square- you need to find the length of one of the sides and then multiply this by itself to find the area.
Answer: length of DE = 18
Step-by-step explanation:
Since the angles of these two triangles are the same, we can assume that they are <em>similar triangles</em>. To solve for a missing side of a triangle that is similar, you can set up a proportion:
To solve for x (the missing length), you would do:
27 × 10 ÷ 15 = 18
You can set up the proportion in any way between the two triangles as long as the two sides correspond to each other. For example, you could have also used the following proportion to solve for x:
When you solve for x using this proportion, you would get the same value for x:
10 × 27 ÷ 15 = 18
