How would I solve for x?​
vaieri [72.5K]

Answer:

x = 65

Step-by-step explanation:

First, we calculate the unknown angle of the left triangle and right triangle:180 - 62 - 50 = 68

Unknown angle for left triangle⬆️

180 - 80 - 53 = 47

Unknown angle for right triangle⬆️

Now we've calculated the two angles for the small triangle in the middle. So, we just have to calculate the top angle of the middle triangle:

180 - 68 - 47 = 65

The angle 65° and angle of x are vertical angle.(both are equal)

So... <u>x= 65°</u>

If a recipe requires 400 grams of potatoes for four people, how many kilograms would be required for 12 people?
Tasya [4]

Answer:

1.2 kg

Step-by-step explanation:

We need 400 grams of potatoes for 4 people. That means each person will require 400 / 4 = 100 grams.

Now, we have 12 people, so the total number of grams needed will be:

(100 g/person) * (12 people) = 1200 grams

However, we want the answer in kilograms. There are 1000 grams in a kilogram, so divide 1200 by 1000:

1200 / 1000 = 1.2 kg

The answer is 1.2 kg.

An investment of 11,000 is made into an account that earns 4.25% annual compound interest for 30 months. Assuming no other depos
LenKa [72]

Answer:

It should be $12168.75

Step-by-step explanation:

First, converting R percent to r a decimal

r = R/100 = 4.25%/100 = 0.0425 per year,

then, solving our equation

I = 11000 × 0.0425 × 2.5 = 1168.75

I = $ 1,168.75

The simple interest accumulated

on a principal of $ 11,000.00

at a rate of 4.25% per year

for 2.5 years is $ 1,168.75.

1,168.75 + 11000 = 12168.75

Radius = 1.25cm
81cm3 / 20 = 4.05 cm3 per cone
V cone = πr^2 (h/3)
So then 4.05 = π(1.25)^2 (h/3)
Then h/3 = .825 and then

h = 2.475 cm
