Explanation

we know that

geometric sequence 8, 16, 32

the question is

the 8th term

the answer is

first we have to find the ratio

[tex] \sf r= \frac{ U_2}{U_1} \\ \sf r= \frac{ 16}{8} \\ \sf r = 2 [/tex]

than, we have to find the 8th term

[tex] \sf U_n = ar^{n-1} \\ \sf U_8 = 8 \times 2^{8-1} \\ \sf U_8 = 8 \times 2^7 \\ \sf U_8 = 8 \times 128 \\ \bold {\sf U_8 = 1024} [/tex]

Kristopher has a coupon for $10 off any item at his favorite electronics shop. If he plans to use the coupon to purchase and item that costs $80, by what percentage will the price be decreased before tax?

Answers

Answer:

12.5%

Step-by-step explanation:

Kristopher has a coupon for $10 off any item at his favorite electronics shop. If he plans to use the coupon to purchase and item that costs $80, by what percentage will the price be decreased before tax?

The formula for Percentage Decrease =

Decrease in price/ Initial price × 100

Decrease in price = $10

Initial price = $80

Hence:

$10/$80 × 100

= 12.5%

Hence, the percentage the price will be decreased by before tax is 12.5%

x = 8

Step-by-step explanation:

2x+5=21

Step 1: Subtract 5 from both sides.

2x+5−5=21−5

2x=16

Step 2: Divide both sides by 2.

2x /2 = 16 /2

x = 8

Answer:

x = 8

Step-by-step explanation:

2x + 5 = 21

2x = 21 - 5

2x = 16

x = 16/2

x = 8

*Slope A*

A good trick to use to find a negative slope is to see if it is falling downwards.

C is ruled out since it is going straight up. B has a slope of -2/1 and you can tell that by counting the distance from the origin to the next point where it touches the line.

the area of a small square is 25 square units what is the exact length in units of a single of a large square

Answers

Answer:

Step-by-step explanation:

The area of any quadrilateral can be determined by multiplying the length of its base by its height. Since we know the shape here is square, we know that all sides are of equal length. From this we can work backwards by taking the square root of the area to find the length of one side.

Write an expression that is equivalent to 3k - 18

Answers

Answer:

3(k-6)

Step-by-step explanation:

I did it on i-Ready and got it right!

A common factor of 3k and 18 that is greater than 1 is 3.

An expression that shows 3k minus 18 is 3(k)-3(6).

An expression that is equivalent to 3k - 18 can be written as follows:

3(k - 6)

Given is an expression 3k-18 we need to an expression that is equivalent to it,

Let's break it down to understand why this expression is equivalent to 3k - 18:

Distributive Property: The expression 3(k - 6) can be expanded using the distributive property, which states that for any real numbers a, b, and c: a(b + c) = ab + ac.

In this case, a is 3, and b is k while c is -6. So we can apply the distributive property as follows: 3(k - 6) = 3k + 3(-6).

Simplification: The term 3(-6) can be simplified to -18, so the expression becomes 3k - 18.

Therefore, the expression 3(k - 6) is equivalent to 3k - 18 because both expressions yield the same result when evaluated for any value of k.

Fred's Fruit Stand has 252 pounds of fruit and sells 2 7/8 pounds per hour. Gary's grocery Store has 285 pounds of fruit and sells 3 1/3 pounds per hour. How many hours until they have the same amount of fruit left?

Answers

Answer:

72.1 hours

Step-by-step explanation:

Let the number of hours be represented as: x

Fred's Fruit Stand has 252 pounds of fruit and sells 2 7/8 pounds per hour.

Convert 2 7/8 pounds to decimal = 2.875pounds

Hence:

252 - 2.875x

Gary's grocery Store has 285 pounds of fruit and sells 3 1/3 pounds per hour.

Convert 3 1/3 pounds to decimal = 3.333 pounds

Hence:

285 - 3.333x

How many hours until they have the same amount of fruit left?

This calculated by equating both equation together

252 - 2.875x = 285 - 3.333x

Collect like terms

-2.875x + 3.333x = 285 - 252

0.458x = 33

x = 33 / 0.458

x = 72.052401747 hours

x ≈ 72.1 hours

They would have the same amount of fruit left after 72.1 hours

If you subtract 14 from my number and multiply the difference by -4, you should get -100.

You need to setup the equation that is being given to you.

Subtract 14 from my number.

x - 14

Multiply the difference by -4

(x-14) * -4

You should get -100.

(x-14) * -4 = -100

Solve for x
