Step-by-step explanation:

There is a little trick to find out if it is a function or not. This trick is called the vertical line test. if you can scan the figure with a virtual line and it does not touch more than one side of the figure at one time then it is a function. if it touches more than one side or line of the figure it is not a function.

Answers

Answer:

78°

Step-by-step explanation:

42+60=102

180-102=78

Answer:

Step-by-step explanation:

first find the final interior angle since we need it to find the exterior

60 + 42 = 102

180 - 102 = 78 degrees

then we just have to do 180 - 78 bc we have a straight line and straight lines are always 180 degrees

180 - 78 = 102 degrees

x = 102

you honestly could just take the 2 values you already know and add them and use that lol

Answer:

x = 6

∠2 = 75

Step-by-step explanation:

In the given triangle two sides are equal and so it is an isosceles triangle. So, the angles opposite to equal sides are equal

11x + 9 + 11x + 9 + 30 = 180   {Angle sum property of triangle}

      11x + 11x + 9 +9 +30 = 180

                     22x + 48   = 180

                            22x    = 180 - 48

                               22x = 132

                                   x = 132/22

                                  x = 6

∠2 = 11*6 + 9 = 66 +9 = 75

the ratio of boys to girls in a class is 4 : 5 how many girls are there in a class if 12 boys are in the class

Answers

Answer:

15

Step-by-step explanation:

Hey! Pretty stranger :D

AsnwEr:

Number of girls in class = 15

GivEn:

The ratio of no. of boys to no. of girls in a class is 4:5.Number of boys in class = 12

To find:

Number of girls in class?

Solution:

☯ Let number of girls be x.

Given that,

The ratio of no. of boys to no. of girls in a class is 4:5.

Therefore,

→ 12/x = 4/5

→ x = 12 × 5/4

→ x = 60/4

→ x = 15

∴ Hence, number of girls in a class is 15.

Olivia filled 4 baskets of apples. Her friend filled up one additional basket of apples. if all of the baskets sold for a total of $160, how much money did each basket of apples cost?

Answers

Answer:

$32

Step-by-step explanation:

Since the question says that all the apples were sold for a total of $160, this means that you have to add the additional basket of the friend's to Olivia's. Since Olivia has 4 baskets of apples and her friend has 1, 4+1=5. Since you're trying to find the unit price for 1 basket, you take the total of $160 and divide it by 5 to find how much each basket of apples costed. Since 160/5 is 32, $32 is your answer.

How do you solve this?
Look at attached file please...I'm really confused!

Answers

Answer:

X=18, Y=6

Step by Step Explanation:

This is a little long winded.. Let's solve for Y first.

First looking at the problem, you can note a few things. First of all, there is an Isosceles triangle, and there is an equilateral triangle. Where they connect, there is a 90° angle.

Now, all equilateral triangles have the same angle measurement. 60°. Now, if you look where the right angle is, it is showing a 60° angle, a total of 90°, and an unknown area. So simply subtract. 90-60=30. Divide that by 5, and you have your answer of 6.

Now let's solve X. X is very simple. On an isosceles triangle, the two top sides are the same length. And one of the top sides is the same size as the equilateral triangle. And on equilateral triangles, all sides are the same.

So the 11 transfers over to the X side. So let's make a small equation. 11=X-7. To make it even, let's add 7 to both sides. 11+7=X+7-7. Simplify to get 18=X, which is your answer.

X=18 y=6
