a box contains 18 blue flashlights 3 red flashlights 7 silver flashlights ans 2 black flashlights. the flashlights are identical in size and shape. if one flashlight is chosen at random what is the probability that the flashlight will be either blue or black?

Answers

Answer 1

Answer:

The answer is 20/30 or in simplified form 2/3

Step-by-step explanation:

The way I do it is I take the probability of blue flashlights, 18/30, added to the probability of black flashlights, 2/30. Then, you simplify by dividing both numbers by 10.

Which number on the number line represents the OPPOSITE of -7/2? Select a place on the number line to plot the point.

Answers

Answer:

the answer would be 3 1/2

Step-by-step explanation:

if you simplify -7/2 it would be -3 1/2, and the opposite of -3 1/2 is 3 1/2.  And from 0-3 there are 6 spaces, so every two spaces counts as 1. Therefore the point would go one spot after positive 3.  

Which of the following expression represents the area of the circle?

O 2π(x+2)
O π(x+2)^2
O π(2x+4)^2
O 2π(2x+4)​

Answers

Answer:

π(x+2)^2

Step-by-step explanation:

The formula for the area of a circle is π*radius squared.

2x + 4 is the length across the entire circle, which would make it the diameter.

The radius is half the diameter.

So, to find out the radius, simply divide the diameter by 2.

2x+4/2

x+2

Now, plug the newly found radius into the formula.

Area=π*(x+2)^2

6. Monthly Mortgage payments can be found using the formula Below:

(1+12"-1

M = monthly payment

P = amount borrowed

r=annual interest rate

n = number of monthly payments

The Ranallo family just bought a house. They qualified for an annual interest rate of 5.2% and their monthly payment

was $800 for a 30 year mortgage. Algebraically determine the amount of their loan to buy the house.

Answers

Answer:  your equation is poorly written/wrong hence I used the equation below

answer :  $289156.63

Step-by-step explanation:

applying the formula to calculate monthly repayment of Mortgage

M = P [ r(1+r)^n / ( ( 1+r )^n ) -1 ) ]  -----  ( 1 )

M = Total monthly payment = 800 * 12 * 30 = $ 288,000

P = ?

r = 5.2% / 12 = 0.4%

n = 30 * 12 = 360 months

Back to equation 1

P = M / [ r(1+r)^n / ( ( 1+r )^n ) -1 ) ]

   = 288000 / [ 0.004 ( 1.004)^360 / (( 1.004)^360 ) - 1 ) ]

   = 288,000 / -0.996  =  - $289156.63 ( It has a negative value because It is a loan borrowed )
