Answers

Answer 1

Answer:

The sum of measures of angles in a triangle is 180. So if you take the three angles, add them, and set it to 180, you will get the answer. (39 + 3x + 7 + 5x - 2 = 180)

Step-by-step explanation:

Answer 2

Answer:

[tex]x = 17[/tex]

Step-by-step explanation:

[tex]m < a + m < b + m < c = 180 \\ \\ 39 + (3x + 7) + (5x - 2) = 180 \\ 39 + 8x + 5 = 180 \\ 44 + 8x = 180 \\ 8x = 180 - 44 \\ 8x = 136 \\ x = \frac{136}{8} \\ \\ x = 17[/tex]

m=(-2-2)/(3-1)

m=-4/(2)

m=-4/2

m=-2

y-y1=m(x-x1)

At a basketball game, for every basket team A scored, team B scored 4 baskets. The ratio of the number of baskets scored by team A to the number of baskets for team B is A. 1 to 3
B. 2 to 3
C. 1 to 4
D. 4 to 1

Answers

Answer:

C. 1 to 4

Step-by-step explanation:

The ratio is used to describe situations like "for how many x's, there are many y's". In this case, we are trying to find the ratio for A baskets scored to B baskets scored, team A scores one basket, then team B will score 4 baskets. Then we can write the ratio of A to B as 1:4, which is 1 to 4.

in the figure given alongside if X=3y find the sizes of angles represented by a and b​

Answers

Answer:

Step-by-step explanation:

x = 3y

x + y = 180°

3y + y = 180° ⇒ y = 45° = a

x = 3( 45° ) ⇒ x = 135° = b

The sizes of angles represented by a and b​ are 45 and 135 degrees.

How does an angle form?

An angle requires two straight line/ line segments/rays, such that they're connected on one of their endpoints.

The point of their joint is called vertex of that angle.

Those two line segments forming it are called arms of that angle.

The angle is the degree of rotation that it will take for the moving side to go from initial side to the position it is currently on.

We are given that

x = 3y

Since we know that the linear pair is

x + y = 180°

Therefore, 3y + y = 180°

y = 45° = a

x = 3( 45° )

x = 135° = b

• The outside temperature changes -4.8°F in 4 hours. What is the average change in temperature each hour?


-19.2°F

-12.2°F

-1.8°F

-1.2°F

Answers

Answer:

-1.2°F

Step-by-step explanation:

-4.8F = 4 hours

Divide both sides by 4 to get one side to 1 hour

-4.8F/4 = 4 hours / 4

-1.2F = 1 hour

The average change in temperature each hour is -1.2°F

What is Division?

A division is a process of splitting a specific amount into equal parts.

Given that the outside temperature changes -4.8°F in 4 hours

We need to find the average change in temperature each hour

To find this we need to use division.

We need to divide -4.8 by 4

-4.8/4

Minus four point eight divided by 4

-1.2

Hence, the average change in temperature each hour is -1.2°F
