I WILL MARK AS BRAINLIEST! Write and equation that represents the points on the table

Answers

Step-by-step explanation:

the general equation :

y = ax +b

2 = 0a+ b => b = 2

4 = -2a + b

4 = -2a +2

2a = 2-4

2a = -2

a = -1

so, y = -x + 2

Y= ab+x
So y= -2+x

Hi! I'm happy to help!

To solve this, we have to divide the 18 pounds, in 1/8 portions. We do this with division. To make this problem easier to solve, we need to turn it into a multiplication problem (opposite of division). To still make the problem correct, we have to take the opposite of one of our numbers. Let's take 1/8, and turn it into 8, now we have the problem:

18×8=

Now all we have to do is multiply:

Calculate The Area

Answers

Answer: 47.25

Step-by-step explanation:

the equation for finding the area of a triangle is base times height divided by 2

10.5(9)= 94.5

94.5/2=47.25

Answer:

47.25 sq ft is the area. no idea what you want me to do with the 4% though

Step-by-step explanation:

area for traingles = (base×hight)÷2

so your equation would he (10.5ft×9ft)÷2

10.5×9= 94.5

94.5÷2÷47.25

so the answer is 47.25 ft^2 (or simply sq ft)

Max makes three piles of cards, each consisting of only a Queen and a Jack. Lisa draws one card from each pile. What is the probability that Lisa draws two Queen and a Jack in any order? Make a tree diagram of all the choices

Answers

Answer:

3/8

Step-by-step explanation:

The probability of picking either a Queen or a Jack from each pile is always 1/2 (as there are only 2 cards).

There are only 3 ways in which Lisa can draw two Queens and a Jack:

Queen, Queen, Jack

Queen, Jack, Queen

Jack, Queen, Queen

The probability of each one happening is 1/8

This is because there is a 1/2 chance of picking a Queen or a Jack from each pile and to calculate the probability that Lisa will pick a Queen AND a Queen AND then a Jack (for example) you multiply the probabilities together:

1/2 x 1/2 x 1/2 = 1/8

This is the same for other examples and since there are only 3 ways that Lisa can draw two Queens and a Jack you multiply 1/8 by 3 (you add 1/8 together 3 times) to get 3/8

It can be represented on a tree diagram however I am not sure how I can show images/drawings on this

3/8 hope this helps

6(9 + 5x) = 54 +

Answers

Hi

to progress in math, you must : know by heart the rules and formulas then train.

rule : a ( b+c ) = a*b + a*c.

this propertie is call distributivity .

so we have : 6 ( 9+5X)

here : a = 6

b = 9

c = 5X

so 6 ( 9+5X) = ?

I let you have a shot. Ask in comments section if you are stuck. But try first !

Answer:

1) rearrange terms:

6(9 + 5x) = 54

6(5x + 9) = 54

2) Distribution :

6(5x + 9) = 54

30x + 54= 54

3) subtract 54 from both side:

30x + 54 = 54

30x + 54 - 54 = 54 - 54

4) Simplify: subtract the numbers

30x = 0

5) Divide both side of the equation by the same term:

30x = 0

30x√30 = 0√30

6) Simplify: cancel term that are in the both numerator and denominator

x = O√30

solution :

x = 0]

15. The floor plan of the basement of a shopping centre is drawn to a scale of 1:400.

If a supermarket has an area of 0.25 m² on the plan, find its actual area in hectares. (1 hectare = 10 000 m²)​

Answers

Answer:

4 hectares

Step-by-step explanation:

The scale factor is:

k = 1/400

Applied to the area we consider k² as the area is the product of two dimensions.

Find the actual area:

0.25 m² : (1/400)² = 0.25 m² * 160000 = 40000 m² = 40000 * 1/10000 hectares = 4 hectares

Find the number that makes the ratio equivalent to 1:5.
6:

Answers

Ratios are also fractions.

1:5 is the same as 1/5.

So, the question really is 1/5 = 6/what?

6/30 is the same as 1/5

So the missing number is 30.

Answer:

box = 30

Step-by-step explanation:

You could set this up very formally as a proportion. It would look like this.

1/5 = 6/x

Now all you have to do is cross multiiply.

1*x = 5 * 6

x = 30

So the answer that goes in the box is 30

Or you could just say to yourself. "The 1 was multiplied by 6. What do I have to multiply the 5 by to keep the ratio the same?"

The answer is 6

6 * 5 = 30

The height of a bookcase is 1.93 meters. Which expression converts this height to feet? Note: 1 foot is approximately 0.3048 meters and 1 meter is approximately 3.2808 feet.

A

B
1.93m×(3.2808ft1m)

C
1.93m×(1m0.3048ft)

D
1.93m×(1m3.2808ft)

Answers

I think it is A not 100%

The expression which converts the height of the bookcase to feet is 1.93 × (3.2808ft / 1m)

To make the conversion of meters to feets , we use dimensional analysis ;

We need to multiply the given measurement in meters by its appropriate or equivalent value in feets :

Recall :

1 meter = 3.2808 feets

Then the height of the bookcase in feets will be :

1.93 meters × 3.2808ft / 1m

Hence, the appropriate expression is : 1.93 meters × 3.2808ft / 1m
