Answer:

48 degrees

Step-by-step explanation:

A triangle has three angles that add up to 180 degrees. In a right triangle, one of the angles in 90 degress, and the other 2 add up to 90. In this case, we have 2 given angles, 90 degree angle and 42 degree angle. If we do 90+42 it gives us 132. We then subtract that from 180 to give us 48 degrees.

marin [14]

Answer:

Same quanitity.

Step-by-step explanation:

The Soup Shack usually makes tomato soup with 9 tomatoes for every 12 bowls of soup.

Today, they made 8 bowls of soup with 6 tomatoes.

We need to compare today's soup to the usual recipe.

For 9 tomatoes for every 12 bowls of soup = \dfrac{9}{12}=\dfrac{3}{4}

For 8 bowls of soup with 6 tomatoes = \dfrac{6}{8}=\dfrac{3}{4}

It means we can see that both the soup has the same quantity. Hence, this is the required solution.

To find the value of r, Stephen rewrites 3r - 18 = 27 as 3(r - 6) = 3(9). How could this help Stephen reason the value of r? Exp
Leokris [45]

Answer: See explanation

Step-by-step explanation:

We are informed that Stephen rewrites 3r - 18 = 27 as 3(r - 6) = 3(9). This is quite thoughtful of Stephen and it's an easier way to solve the question.

In this case, 3 is a common factor to 3r, 18 and 27. Therefore, we will then have: 3(r - 6) = 3(9).

Since 3 is a common base to both, we are more concerned with the values inside the brackets. This will be:

r-6 = 9

r = 9 + 6

r = 15

Check: 3r - 18

3(15) - 18 = 45 - 18 = 27
