What is the rate of change between the first and second point?

Answers

it would be -1/2 because the formula to find slope (rate of change) is (y2-y1)/(x2-x1) and in this case it would be (4.5-2)/(-3--2) which simplifies to (2.5)/(-5) which is -1/2

how many faces does this shape have?

Answers

This is a triangular pyramid and has 4 faces.

Answer:

5

Step-by-step explanation:

Faces is essentially the number of sides. In an easier shape like this you could just count the number of sides. You would have 5 faces in this shape.

On a side note, when dealing with convex polyhedrons(you might not have gotten into this) you can find the number of edges by by adding the number of vertices, plus the number of vertices, minus 2.

For example, lets take a cube. The cube has 6 faces and 8 vertices. 6 + 8 - 2 = 12 edges

Jim is baking cookies. He only wants to make 2/3 of a batch of cookies. The recipe calls for 7/8 of a cup of milk. How much of a cup of milk should he use? *

Answers

Answer:

1 5/16 cups

Step-by-step explanation:

If the recipe calls for 7/8 cup of milk for 1 batch of cookies, then we divide 2/3 by 7/8. 7/8 * 3/2 = 21/16 = 1 5/16 cups.

7/8 of a cup of milk divided by 2/3 of a batch. No

10 pounds of Cat Food A costs $6.50. For 20 pounds of Cat Food B it is $14.00. Which cat food is the better deal? Write the answer as the dollar amount for one pound of the better deal. ($_.__)

Answers

Answer:

cat food a

Step-by-step explanation:

6.5/10 = 0.65 unit price

14/20 = 0.70 unit price

Cat Food A has the better deal.

What do we know? :
10 pounds (Cat Food A / C.F.A) = $6.50
20 pounds (Cat Food B / C.F.B) = $14.00

Finding which one is the better deal :
If 10 pounds of C.F.A (Cat Food A) is $6.50, if we double the pounds, and cost, we would get 20 pounds of C.F.A for $13.00. This means you can get the same amount of pounds in C.F.A and C.F.B, and costs for 1 dollar less.

(Another way to solve this) :
Dividing the cost by pound.
C.F.A : 6.50 / 10 = 0.65
So, each pound of Cat Food A equals 0.65 cents.

C.F.B : 14.00 / 20 = 0.7
So each pound of Cat Food B equals 0.70 cents.

Conclusion :
In conclusion, both ways can be used to correctly solve this question, and both have the same results. Which is that Cat Food A is the better deal.

a) they are lighter

b)lighter by 0.0042 pounds

Answer:

A. The label is heavier than the actual weight.

B. The actual weight is 0.0042 less than the labeled weight.

Step-by-step explanation:

I hope I'm correct but here's my explanation.

A. The label said it is 0.384 and the actual weight is 0.3798, which in terms of suggesting the label is just 0.3840 and the actual weight is 0.3798, then the labeled weight would be heavier since it has either rounded up or was guessed.

B. The actual weight is 0.3798 and the labeled weight (assuming after the last decimal number it is zero) would be 0.384. Subtract, and it would be 0.0042.

Though I'm not sure if I'm 100% correct, I do think this might be the most accurate way to solve this.

Answers

Answer:

12(x+ 30)

Step-by-step explanation:

360 is the down payment and 12x is the monthly payment

With regards to the function as monthly we realise there are 12 months in a year so it could equally mean (12 months x amount) or $12 dollars multiplied by x)

Factorising  We always put the highest common factor outside of the brackets when dealing with 2 numbers that can include variables such as x or 12x counting as one of the two.

12x+360

12(x+ 30)

Which is done as 12 x 30 = 360

We always try units first in numbers end in zero ie) 30 into 60 is x2 and 30 into 300 is 10 so our first highest common factor is 12 as its our largest number available from the smallest number given being 12.

So 12 is our highest common factor.

A common factor is a factor that is shared by two or more numbers. For example, a common factor of 8 and 10 is 2, as 2 is a factor of 8, and 2 is also a factor of 10. The highest common factor (HCF) is found by finding all common factors of two numbers and selecting the largest one
