Since this is a right triangle, the sides are related by the Pythagorean theorem. a^2+b^2=c^2

Legs are a and b. Hypotenuse is c. Plugging in the values gives you:

9^2 + 12^2 = x^2
81 + 144 = x^2

X^2 = 225

Taking the square root of both sides gives you x=15

Marie plants flowers in a planter that is 1 1/2 feet long and 1 2/3 feet wide. She plans to cover the entire area with fertilize

Arisa [49]

Answer:

2 3/6

Step-by-step explanation:

You must turn 1 2/3 and 1 1/2 into improper fractions. You then multiply them and get an answer of 15/6, but since 6 can go into 15 twice (6x2=12+3=15), you get a whole of 2 and 3/6.

Need Help on Both of these, Will give 50 Points to answerer:

Part A: Scatter plot with best-fit line attached. You'll find the line to have equation (approximately)

$y=51.34+3.98x$

The positive slope suggests that test scores and study time are directly are proportional.

Part B: Same as in a previous question you had posted. Pick two points on the provided line and compute the slope as best you can. For example, I might pick (2, 30) and (4, 40), which gives a slope of

$\dfrac{40-30}{4-2}=5$

and assuming the line passes through (2, 30) exactly, it would have equation

$y-2=5(x-30)\implies y=5x-148$

Karen's fish tank has 13 liters of water in it. She plans to add 4 liters per minute until the tank has at least 57 liters. What

guapka [62]

Answer:

Karen has to at least spend 11 minutes.

Step-by-step explanation:

This is because 57 - 13 = 44. 44 divided by 4 = 11. This means that in 11 minutes Karen will have a 57 liter tank. But she could keep going, but the least number of minutes would be 11 minutes, to get to 57 liters.

I hope this helps! Please mark me Brainliest if it did! Thank you and have a nice day!
