Determine whether the relationship between the number of heart beats and the time shown in the graph is proportional. Explain your reasoning.

Answers

Answer:

This is proportional

Step-by-step explanation:

Your slope is 2 each time. To find slop you do rise/run. go to a dot and go up 2 and over 1. Simplify that and you get a slope of 2. Keep doing that for each point then you can determine if it is proportional or not. In this case it is. Hope this helps :)

Yes proportional because the slope is constant

Suppose you want to put a frame around the painting shown at the right. The frame will be the same width around the entire painting. You have 276 in.2 of framing material. How wide should the frame be?

Answers

Answer:

The frame should be 36 + 2b + 16 + 2b

Step-by-step explanation:

To solve this question, let assign 36 in x 16 in as the dimension of the painting.

276 in^2 is the area of the framing material to be used.

Let the width of the frame around the frame be "b", thus; the dimension of the frame is 36 + 2b + 16 + 2b

Moneysaver's Hank offers savings account that eams 3% interest compounded continuously. If Lucy deposits $1200, how much will have in the account after six years, assuming she makes no withdrawals?

Answers

Answer:1442.41086

Step-by-step explanation:

So first it would continue 3% higher so not 18% higher

first 3% higher 1200

So 1236

Then 3% of 1236

so 1273.08

The 3% of that to 1311.2724

The 3% of that to 1350.61057

The 3% of that to 1400.39889

The 3% of that to 1442.41086

Answer:

1251

Step-by-step explanation:

Use the formula for calculating compound interest A=P0ert where A is the unknown, P0=1200, r=0.014, and t=3. Substitute the values into the formula and simplify.

A=1200e0.014⋅3

A=1200e0.042

A=1200(1.0428...)

A=1251.47

Therefore, after three years, the balance in the account is A≈1251.

The HCF of two numbers is 20. The LCM of both numbers is a multiple of 14. One number is greater than the other, work out the smallest possible values of both numbers.

Answers

Answer:

The smallest combination of the numbers is 20 and 140

Step-by-step explanation:

The given parameters are;

The Highest Common Factor HCF of the two number = 20

The Lowest Common Multiple LCM of both numbers = Multiple of 14

Let x and y represent the two numbers, we are given;

x > y

We have;

[tex]L.C.M. = \dfrac{Product \ of \ the \ numbers}{H.C.F.}[/tex]

Substituting the known values, we have;

[tex]x \times 14 = \dfrac{Product \ of \ the \ numbers}{20}[/tex]

The product of the numbers = x × 14 × 20

The possible products of the numbers are;

280, 560, 840, 1,120, 1,400, 1,680, 1,960, 2,240, 2.520, 2,800, 3,080, 3,360, 3,640, 3,920

Dividing the possible products by 20 gives, the smallest quotient that is also a multiple of 20 as 140, from which we have;

20 × 140 = 2,800

Therefore, the smallest combination of the numbers = 20 and 140.

Factor 5x^2-11x+6. Rewrite the trinomial with the X-term expanded using 2 factors

The answer starts as 5x^2_______+6

Answers

Answer:

[tex]5x^2-5x-6x+6[/tex]

Step-by-step explanation:

[tex]5x^2-11x+6\\5x^2-5x-6x+6[/tex]

we need to factorize it so the X-term expanded should satisfy two conditions

1) +5 times +6 should be +30

2) add or subtract any two numbers which multiply and give -11

so here -5 times -6 gives +30 and -5 added to -6 equals -11

Leanna opens a savings account with an initial balance of $100. She then
deposits $50 each month. She currently has $450. How many months has she
been saving for?

Answers

Answer:

7

Step-by-step explanation:

450-100=350

350/50=7

7 months

Leanna has been saving for 7 months to have the balance of $450.

What is a linear equation?

It is defined as the relation between two variables if we plot the graph of the linear equation we will get a straight line.

If in the linear equation one variable is present then the equation is known as linear equation in one variable.

Let's suppose the Leanna has been saving the money for 'x' months

It means total months = x

Intial balance = $100

Each month she deposit = $50

After x months she will have  = $450 (with initial balance)

We can frame a linear equation in one variable such that:

50x = 450 - 100  (without initial balance)

50x = 350 (divide by 50 on both sides)

x = 7 months

Thus, Leanna has been saving for 7 months to have the balance of $450.
