The value of the numerical expression {[(30 − 60) ÷ (−30)]² − 15} ÷ (−7) will be 2.

What is the value of the expression?

When the relevant factors and natural laws of a mathematical model are given values, the outcome of the calculation it describes is the expression's outcome.

The expression is given below.

⇒ {[(30 − 60) ÷ (−30)]² − 15} ÷ (−7)

Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction are all part of the PEMDAS formula. To answer the problem properly and accurately, this rule must be followed.

⇒ {[(30 − 60) ÷ (−30)]² − 15} ÷ (−7)

⇒ {[(−30) ÷ (−30)]² − 15} ÷ (−7)

⇒ {[1]² − 15} ÷ (−7)

⇒ {1 − 15} ÷ (−7)

⇒ (−14) ÷ (−7)

⇒ 2

The value of the numerical expression {[(30 − 60) ÷ (−30)]² − 15} ÷ (−7) will be 2.

Answer:

(- 3, 0 ) and (5, 0 )

Step-by-step explanation:

To find the x- intercepts let f(x) = 0 , that is

x² - 2x - 15 = 0

Consider the factors of the constant term (- 15) which sum to give the coefficient of the x- term (- 2)

The factors are - 5 and + 3 , since

- 5 × 3 = - 15 and - 5 + 3 = - 2 , then

(x - 5)(x + 3) = 0 ← in factored form

Equate each factor to zero and solve for x

x - 5 = 0 ⇒ x = 5

x + 3 = 0 ⇒ x = - 3

The x- intercepts are (- 3, 0 ) and (5, 0 )

Both loans are paid monthly, and their interest is compounded monthly. Calculate the absolute difference between the total interest paid on both loans. Round your answer to the nearest cent.

Answers

53.5 dollars is the total interest paid on both loans.

What is Compound Interest ?

Compound interest is the addition of interest to the principal sum of a loan or deposit, or in other words, interest on principal plus interest.

Loan A :

CI = P(1 + R/100)∧(T) - P

CI = 5000(1 + 12/100)∧(5/2) - 5000

CI = 1637.66

Loan B :

CI = P(1 + R/100)∧(T) - P

CI = 5000(1 + 6/100)∧(5) - 5000

CI = 1691.13

difference between two CI

= 1691.13 - 1637.66

= 53.47

= 53.5 dollars

A dairy needs 357 gallons of milk containing 5% butterfat. How many gallons each of milk containing 7% butterfat and milk containing 1% butterfat must be used to obtain the desired 357 gallons?

Answers

9514 1404 393

Answer:

238 gallons 7%119 gallons 1%

Step-by-step explanation:

Let h represent the number of gallons of high butterfat content milk. Then 357-h will be the number of gallons of 1% milk. The total amount of butterfat in the mix is ...

  0.07h +0.01(357 -h) = 0.05(357)

  0.06h = 14.28 . . . . . . . . . . subtract 3.57, collect terms

  h = 238 . . . . . . . . . .  divide by 0.06

  357-h = 357 -238 = 119

238 gallons of 7% and 119 gallons of 1% are needed.

The area of a bulletin board is 90 ft. The length is nine feet less than four times the width. Find the length and the width, in feet, of the bulletin board.
width
ft
length
ft
+

Answers

Area (A) = 90 ft
Width = x
Length = 4x - 9

A = L*W, so the equation is:
x(4x - 9) = 90

Solve:
4x^2 - 9x = 90
4x^2 - 9x - 90 = 0
(4x + 15)(x - 6) = 0
4x + 15 = 0
4x = - 15
x = -15/4
^^^ reject because distance can’t be negative
x - 6 = 0
x = 6 ft (width)

Length = 4x - 9
L = 4(6) - 9
L = 24 - 9
L = 15 ft

Check:
A = L*W
90 = 15 * 6
90 = 90

Answer: The length is 15 feet and the width is 6 feet.

A down payment of $195 is made on a television that costs $1300. What percent of the
cost is the down payment?

Answers

6.66666667% I hope that is helpful to you

Answer:

15%

Step-by-step explanation:

Add 195 to 1300, which gives you, 1495.

Use the formula for percent change:  Difference = % * original price.

So what is the difference between 1495 and 1300? It’s 195.

Now we have 195 as the difference.

Do we know the original price of the TV? Yes we do. What is it? Its 1300 because the question states the TV costs $1300.

Now we have the equation 195 = % * 1300

We don’t know the percentage, right? So now we have to solve for %. To do that, you have to do 195 divided by 1300, which gives you 0.15. Lastly, you have to turn 0.15 into a percentage, to do that, multiply 0.15 by 100, and it should give you 15%.

Therefore, 15% is the down payment. Hope this helps!

-5x+6y=30
-5x+6x0=30
-5x+0=30
-5x=30
X=-6

Answer:

slope-intercept is 5/6x, y intercept is 5 and x intercept is -6

Step-by-step explanation:

-5x+6y=30

first you are going to move your thirty to the other side of the equation so your going to minus 30 from both sides.

-5x+6y(-30)= 30(-30)

-5x+6y-30=0

then move your y to the other side of the equation

-5x-30=6y

divide by 6 to get y alone

-5/6x -(30/6)=y

-5/6x-5=y

therefore your slope is 5/6x, your y intercept is 5 and your x intercept is -6

Is x-10 a factor of f(x)=5x^3+60x^2+109x+90

x = -10.

Given Polynomial is 5x^3+60x^2+109x+90 .
