Answers

Answer 1

Answer:

Answer: wouldn't be 18 m because half is 9 m.

HOPE THIS HELPS :D

Answer 2

Answer:

Answer:

A≈926.54

Step-by-step explanation:

π r 2 + π L r , \pi r^2 + \pi L r, πr2+πLr, where r denotes the radius of the base of the cone, and L denotes the slant height of the cone.Using the formulas

A=πrl+πr2

l=r2+h2

Solving forA

A=πr(r+h2+r2)=π·9·(9+222+92)≈926.54225

Trina uses 1/2 of sugar and 3/4 cup of flour in a recipe. How many cups of sugar would she need if she uses 3 cups of flour?

Answers

Answer:

$2\ cups\ of\ sugar$

Step-by-step explanation:

we know that

Trina uses $1/2$ cup of sugar and $3/4$ cup of flour in a recipe

by proportion

Find how many cups of sugar would she need if she uses $3$ cups of flour

$((1/2))/((3/4))(cups\ of\ sugar)/(cups\ of\ flour)=(x)/(3)(cups\ of\ sugar)/(cups\ of\ flour)\n \n x=3*(1/2)/(3/4)\n \nx=2\ cups\ of\ sugar$

2 cups. You have 4 servings of flour so you need 4 servings of sugar.

An object moves at a constant rate. The graph shows the object's height at different times.Which equation represents the situation?

A.
y = −15x + 900

B.
y = −15x − 900

C.
y = 15x − 900

D.
y = 15x + 900

Answers

With linear graphs, there's two things you need to find, the y intercept and the slope. The y intercept is literally where the line touches the y axis. Looking at the graph you can see that it's at 900, so your number by itself has to be +900. The slope then is found by seeing how much y changes for every change in x. So you have two points, (20,600) and (40,300) which tell you that the line moves down 300 when it moves across 20. Your slope is then -300/20 which is -15. This goes in front of your x and you get your equation. SO your answer would be

A. y = −15x + 900
