Answers

Answer:

3a. yes

3b. y= 75x

3c. 600 mi

3d. 10 inches

Step-by-step explanation:

3a: if you divide the y by the x, you'd get 75 everytime, meaning it's proportional.

3b: y would equal the amount of inches multiplied by 75, so y=75x

3c: you can use the equation and substitute the x for 8, so y=75(8), giving you 600 miles

3d: you can also use the equation in reverse, if the actual miles is 750, then this is your y, so it would look like 750=75x and to solve you'd divide, 750/75, giving you 10 inches

Find the value of x explain how you got your answer ​

Answers

Answer:

step 1: x+50+4x=90

the angle of a right-angled triangle is 90 degrees, therefore if we add everything together ,we could work out what x is.

step 2: x+50+4x=90

                  x+4x=50

                      5x=50

                        x=10

then you solve the equation, x is 10

simon will deposit $250 into two savings accounts. account 1 earns 1.6% interest compounded annually. account 2 earns 1.6% simple annual interest. if simon makes no additional deposit or withdrawals, which account is closest to the difference in the interest that the account will have earned at the end of 10 years. A. $253.01 B.$43.01 C.$83.01 D.$3.01

Answers

The difference in the interest that the account will have earned at the end of 10 years is of:

D. $3.01.

What is the account 1 interest earned?

The amount of interest earned, in compound interest, after t years, is given by:

[tex]I(t) = P\left(1 + \frac{r}{n}\right)^{nt} - P[/tex]

In which the variables are listed as follows:

P is the principal.r is the interest rate, as a decimal value.n is the number of times that interest is compounded per year, annually n = 1, semi-annually n = 2, quarterly n = 4, monthly n = 12.

In the context of this problem, these parameters are given as follows:

P = 250, r = 0.016, n = 12, t = 10.

Hence the interest earned by account 1 is:

[tex]I(10) = 250\left(1 + \frac{0.016}{12}\right)^{12 \times 10} - 250 = 43.35[/tex]

What is the account 2 interest earned?

For simple interest, the amount of interest earned is:

I(t) = Prt.

Hence:

I(10) = 250 x 0.016 x 10 = 40.

Hence the difference is:

43.35 - 40 = $3.35.

Which is closest to option D.

Answer:

solve the equation by rewriting in exponential form using the definition of a logarithm and simplifying.

Exact Form:

x=  1/10000

Decimal form:

x=0.0001

Hopes this helps:

Answer: x = 1/10000

1. Use definition of common logarithm:
b^a = x if and only if logb (x) = a.
X = 10^-4


2. Use negative power rule x^-a = 1/x^a.
X = 1/10^4


3. Simplify 10^4 to 10000.
X = 1/10000

Simplify to -30-35y=-30-5y
Move all ys to the right and move constants left, -30y= 0
Divide by -30
y=0

Answer:

y = 0

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

−5(6+7y)=−5(6+y)

(−5) (6) + (−5) (7y) = (−5) (6) + (−5) (y) (Distribute)

−30 + − 35y = −30 + −5y

−35y − 30 = −5y −30

Step 2: Add 5y to both sides.

−35y − 30 + 5y = −5y −30 + 5y

−30y −30 = −30

Step 3: Add 30 to both sides.

−30y − 30 + 30 = −30 + 30

−30y = 0

Step 4: Divide both sides by -30.

−30y /−30  =  0 /−30
