Answer:

750 grams of protein, 222.22 of fat, and 1,250 of carbs.

Step-by-step explanation:

3,000 calories from protein, 2,000 from fat, and 5,000 from carbs.

3000 / 4 = 750 grams of protein.

2,000 / 9 = 222.22 grams of fat.

5,000 / 4 = 1,250 grams of carbs.

How do i find the radius? please help :(
Rus_ich [418]

Answer:

r = 40/π   exact answer

r = 12.7 decimal approximation

Step-by-step explanation:

arc length formula

s = (∅/360) * 2πr

s = (∅/180) * πr

--------------------------------

Plug in the givens

10 = (45/180) * πr

10 = .25πr

Divide both sides by .25

40 = πr

divide both sides by π

40/π = r

r = 40/π   exact answer

r = 40/3.14

r = 12.7 decimal approximation

The angles of a triangle add up to 180 degrees.
Alex_Xolod [135]

Answer:

33°

Step-by-step explanation:

We were given that:

1- The angles of a triangle add up to 180 degrees

2- The second angle is 15 degrees larger than the smallest angle

3- The third angle is 3 times as big as the smallest angle

So, first of all, let's call the smallest angle x.

the second angle will be (x + 15°) since it is 15 degrees greater than the smallest angle

and the third will be 3x, since it is 3 times bigger than the smallest angle.

With the information we have, we can form an equation!

180° = x + (x+ 15°) + 3x

180° = 5x + 15°

180° - 15° = 5x + 15° - 15°

165° = 5x

165°/5 = 5x/5

33° = x

therefore, the smallest angle measures 33° degrees, the second angle measures 48° and the third angle measures 99°.

99° + 33° + 48° = 180°

so it is safe to say this answer is correct!

2/3(18x - 12) = 7 – 3(x –3)​
julsineya [31]

Answer:

x=8/5

Step-by-step explanation:

2/3(18x-12)=7-3(x-3)

2/3(18x-12)=7-3x+9

12x-8=-3x+16

12x-(-3x)-8=16

12x+3x-8=16

15x-8=16

15x=16+8

15x=24

x=24/15

simplify

x=8/5

I need help with these two!! thanks!!!
aniked [119]

Answer:

11: Diameter

13: 10 cm

Step-by-step explanation:

Diameter is a straight line across a circle.

It would be 10 because if you cut 20 in half, which is the whole distance of the line, you would get 10.
