The cost of Sara’s Cell Phone is $200 plus $45 per month.

How much will she spend on the cell phone in 3 years?

…. If Sara spent $1500, how long would she have had the phone?

(Use Cost ((y=mx+b))

Answers

Answer 1
1. 1,820
2. Around 29 months
Answer 2

Answer: The cost of her phone is $1,820.

45*12=540 per year

540*3=1,820 every 3 years.

She would have had the phone between 2 and 3 years if she had spent 1,500.

Answers

Statements and reasons.

1) ∠1 and ∠3 are supplementary

Reason: This is true because it is stated in the question.

2) ∠1 + ∠3 = 180º

Reason: By statement 1, ∠1 and ∠3 are supplementary, and by definition, supplementary angles sum up 180º.

3) ∠2 = ∠3

Reason: From the picture we see that ∠2 and ∠3 are opposite congruent angles, so they are equal.

4) ∠1 + ∠2 = 180º

Reason: from statement 2 we have ∠1 + ∠3 = 180º, and from statement 3 we have ∠2 = ∠3, so we have ∠1 + ∠2 = 180º.

5) ∠1 and ∠2 are supplementary

Reason: from statement 4 we have that ∠1 sum up ∠2, so by definition ∠1 and ∠2 are supplementary.

6) line m || line n

Reason: from the picture we see that ∠1 and ∠2 are internal collateral angles of the lines m and n, and from statement 5 we know that ∠1 and ∠2 are supplementary, so we have that the angle between line m and line n is 180°, and by definition, they are parallel lines.

Summary of the reasons

1) It is stated in the question

2) By statement 1 and by definition of supplementary angles.

3) Because they are opposite congruent angles, so they are equal.

4) By statement 2 and 3.

5) By statement 4, and by definition of supplementary angles.

6) By picture ∠1 and ∠2 are internal collateral angles of the lines m and n, and by statement 5 they are supplementary so they are parallel lines.

Mean of the number of adults (out of the sample of 38) with blood type b- positive (x) is 3.04

Let x be the number of adults out of 38 with blood type b-positive

Similarity Theorems

Triangles ABG and DCB are similar by the AA similarity postulate

"If two angles in one triangle are congruent to two angles in another triangle, then the two triangles are similar"

The steps previous to statement 7 prove angles C and B are congruent because they are formed by two parallel lines that intersect a common line.

On the other side, angles DBC and AGB are congruent also because they are both right angles.

With two corresponding congruent angles, the AA similarity postulate is satisfied and the triangles are similar.

The slope of the line is represented by the word m which is obtained as 0.5.

What is the slope?

The ratio that y increase as x increases is the slope of a line. The slope of a line reflects how steep it is, but how much y increases as x increases. Anywhere on the line, the slope stays unchanged (the same).

[tex]\rm m =\dfrac{y_2-y_1}{x_2-x_1}[/tex]

To determine a line's inclination or steepness, use the slope formula. Calculating the ratio of the change in the y-axis to the change in the x-axis may be used to calculate the slope of any line.

From the graph, the data is observed as,

(x₁,y₁)=(0,1)

(x₂,y₂) = (-2,0)

The slope of the line is found as,

[tex]\rm m =\dfrac{0-1}{-2-0} \\\\ m = 0.5[/tex]

Thus, the slope of the line is represented by the word m which is obtained as 0.5.

Divide both sides by 2 to isolate y

2/2 y = -1/2x + 7/2

y = -1/2x + 3 1/2

Now we fill in your chart

Enter this on your chart at 0x.

From here, we see our slope or rate of change is - 1/2 for every x value. So moving to the right from 0

Jennifer has a collection of weights that each weigh 4, 6, or 9 pounds. If altogether, the weights weigh 42 pounds, what is the largest number of weights Jennifer could own?

Answers

The largest number of weights Jennifer could own is 798.

When do we use multiplication?

Repeated addition of the same number is made easier by multiplying the numbers. When we need to merge groups of similar sizes, we employ it. For instance, if there are 5 baskets, each containing 4 apples, we can use multiplication to get the total number of apples, which is 5 x 4 = 20 apples.

We can rapidly determine the total number of things by multiplying. When multiplying, we'll consider the number of groups with similar sizes and the number of items in each group.

Given: The collection of weights : 4 , 6 and 9 pounds

The total weight of the weights = 42 pounds

Thus the largest number of weights jennifer could own is 4+6+9 = 19 multiplied  by the total weight of the weights

= 19 × 42

= 798.
