At the same time a 32-foot water tower casts a 14-foot shadow , a nearby light posts a casts a 7-foot shadow. How tall is the li

Serhud [2]

To solve this problem you can use proportions. The shadow of the water tower and light post are a match, and the height of the water tower and light post are a match. Since we are finding the height of the light post we can replace it with x. The proportion can be set up like this: x/32=7/14. First, multiply 32 and 7 which equals 224. Then take 224 and divide it by the leftover number, 14, and you get 16. So, the answer is c).

PLEASE HELP <br> The following table gives the heights and weights of 10 friends

ohaa [14]

Graph is attached.

Based on the graph (with height on the independent axis and weight on the dependent), there is a negative correlation between height and weight; as the height increases, the weight decreases.

If we were to graph this with weight on the independent axis and height on the dependent, there would still be a negative correlation.

PLEASE HELP ME- KEEP GETTING 1.44x10 to the 9 power! WILL GIVE BRAINLIEST

KIM [24]

So you multiply the first factors, which will get you 14.4 and you add the powers together which will get you 10^8. Since 14.4 is not acceptable, you move the decimal and add 1 to the power which will get you 1.44 x 10^9

hope that helps :)

Answer:

a) 7 equal sized pieces of 3/8 pounds

7* 3/8 = 21/8

b) 3 equal sized pieces of 7/8 pounds

3* 7/8 = 21/8

Step-by-step explanation:

Martin has 2 5/8 pounds of ground beef.

2 5/8 = 21/8 pounds = 2.625 pounds

Because 21 is divisible by 3 and 7, we can arrange the ground beef in two configurations

a) 7 equal sized pieces of 3/8 pounds

7* 3/8 = 21/8

b) 3 equal sized pieces of 7/8 pounds

3* 7/8 = 21/8
