Linear, y=6x-21

Step-by-step explanation:

Graph the answer to get an idea of the shape: linear.

Use y=mx+b and m=y2-y1/x2-x1 to find formula

m=y2-y1/x2-x1=3-(-9)/4-2=12/2=6

y=6x+b

9=6(5)+b

9-30=b=-21

y=6x-21

There are 16 people on the bus. Some adults and some are children. There are more adults than children. Write down different ratios of adults to children that might be on the bus.

Answers

Answer:

11 : 59 : 713 : 3

Step-by-step explanation:

There are more adults than children so the ratios made have to depict this.

These ratios should add up to 16.

Three different ratios:

11 adults : 5 children

9 adults : 7 children

13 adults : 3 children

The above will all add up to 16 and show more adults than children.

The different ratios of adults to children that might be on the bus is;

14 : 2, 13 : 3, 12 : 4, 11 : 5, 10 : 6, 9 : 7

We are given;

Number of people on the bus = 16

The people on the bus consist of adults and children.

We are told that;

There are more adults than children.

Thus, the different possibilities for ratio between

adults and children will be 2 numbers that add up to 16 which must not be equal. Thus, we have;

14 : 2

13 : 3

12 : 4

11 : 5

10 : 6

9 : 7

An isosceles triangle has two congruent side lengths of 20 centimeters. The base of the triangle is 10 centimeters. Find the height of the
isosceles triangle

(Use the Pythagorean Theorem & DONT GIVE ME THE ANSWER, I JUST WANT THE EQUATION) Thx :)

Answers

Answer:

(half of base)² + (height)² = (20)²

Step-by-step explanation:

In an isosceles triangle, the angle bisector from the 3rd angle to the opposite side is a perpendicular bisector, so you split the isosceles triangle into two congruent right triangles.

This technique of 'splitting the isosceles' is used a LOT.

Answers

Answer:

A= 20 + 0.75*j

Step-by-step explanation:

Giving the following information:

You have $20 and earn $0.75 for each cup of orange juice you sell.

To calculate the total amount of dollars (A), we need to use the following formula:

Add a grocery store bananas cost $.90 each and oranges cost $.80 each Ava has $15 to spend if Ava wants to buy an equal amount of bananas and oranges at most how many of each can't you buy

Answers

Answer:

9

Step-by-step explanation:

We are given that

Cost of each banana=$0.90

Cost of each orange=$0.80

Ava have total money=$15

We have to find the number of each if Ava wants to buy an equal amount of bananas and oranges at most.

Let x be the number of each.

According to question

[tex]0.9x+0.8x=15[/tex]

[tex]1.7x=15[/tex]

[tex]x=\frac{15}{1.7}[/tex]

[tex]x=8.8\approx 9[/tex]

Number of oranges bought=9

Are 25 milligrams lighter or heavier than 25 centigrams
Please help it's for homework and it says explain too so please help

Answers

Answer:

25 mg. is lighter than 25 cg.

Step-by-step explanation:

Well,

The prefix "milli" means thousandth and the prefix "centi" means hundredth.  So a milligram will be one-tenth of a centigram.

10 mg. = 1 cg.

25 mg. = 2.5 cg.

2.5 cg. < 25 cg.

25 mg. is lighter than 25 cg.

Answer:

25 milligrams are lighter, because 1 milligram equivales to 1 gram multiplied by 100.
