Answer:

area = 26 cm²

Step-by-step explanation:

The formula for the area of a triangle is: area = $\frac{1}{2}bh$

Where b = the length of the base and h = height.

In the given problem h = 4 cm and b = 13 cm, so we can plug these values into the equation and multiply:

area = $\frac{1}{2}(4)(13)=\frac{1}{2}(52)=26cm^{2}$ .

Amelia need 1/2 stick of butter to make cornbread he also needs one fourths stick butter to make apple muffins what fraction of

Viktor [21]

Amelia needs $\frac{3}{4}$ stick of butter to make cornbread and apple muffins.

Step-by-step explanation:

Given,

Stick of butter needed to make cornbread = $\frac{1}{2}$

Stick of butter needed to make apple muffins = $\frac{1}{4}$

Total stick of butter needed = Cornbread + Muffins

Total stick of butter needed = $\frac{1}{2}+\frac{1}{4}$

Total stick of butter needed = $\frac{2+1}{4}$

Total stick of butter needed = $\frac{3}{4}$

Amelia needs $\frac{3}{4}$ stick of butter to make cornbread and apple muffins.

~SHOW ALL OF YOUR WORK~ Find the volume of this figure. Round to the nearest tenth.

ASHA 777 [7]

Answer:

Rounded to the Nearest Tenth is V=769.3π

Step-by-step explanation:

The diameter of the figure is 7, so the radius is 3.5. So, the radius is 3.5

The height is 20

Formula for cylinders= V= Bh or V=πr2h

I will use V=πr2h

V=π(3.5)²(20)

V=π(12.25)(20)

V=π(245)

V=769.3π

for 8 days of very hot weather, the water level in a lake dropped 3 inches per day. on the ninth day, storms raised the level 6

Marat540 [252]

Hi there!
Your question is:
For 8 days of very hot weather, the water level in a lake dropped 3 inches per day. on the ninth day, storms raised the level 6 inches. Write and find the value of an expression for the change in the water level of the lake during these 9 days.Here is my answer:

If the water level drops 3 inches per day for eight days, it would have gone down a total of 24 inches over those 8 days. Now, the rain storm added 9 inches of water back to the lake. 24 - 9 = 15.
Summary:
8 x 3 = 24
-24 + 9 = -15.

I hope this helped you, and dont hesitate to ask me for anymore help if you need it.

Stay Crazzzzzy! xD
