Solve for x in the diagram below.

Solve For X In The Diagram Below.

Answers

Answer 1

Answer:

x = 20

Step-by-step explanation:

x + 2x + (x + 10) = 90° (right angle)

x + 2x + x + 10 = 90

Add like terms

4x + 10 = 90

4x = 90 - 10 (substraction property of equality)

4x = 80

x = 80/4 (division property of equality)

x = 20

Which is an equation of the line that passes through the points (-6, 3) and (2, 7)?

Answers

Answer:

slope: 1/2

y: intercept: (0;6)

so B

The equation of the line is y = x/2 + 6 which passes through the points (-6, 3) and (2, 7) option (B) is correct.

What is a straight line?

A straight line is a combination of endless points joined on both sides of the point.

The slope 'm' of any straight line is given by:

[tex]\rm m =\dfrac{y_2-y_1}{x_2-x_1}[/tex]

It is given that:

The line that passes through the points (-6, 3) and (2, 7)

The equation of the line:

y - 7 = (7 - 3)/(2 + 6)[x - 2]

The ratio that y increase as x increases is the slope of a line. The slope of a line reflects how steep it is, but how much y increases as x increases. Anywhere on the line, the slope stays unchanged (the same).

y = (1/2)x - 1 + 7

y = x/2 + 6

Thus, the equation of the line is y = x/2 + 6 which passes through the points (-6, 3) and (2, 7) option (B) is correct.

Answer:

change in buyer tastes.

Step-by-step explanation:

Buyers now want more donuts than the other goods.

increase in the cost of donuts is more likely to decrease the amount of donuts consumed, as they would be more expensive

consumers expecting something doesn't necessarily change anything, as they haven't yet dropped and therefore it's unlikely they'd increase the demand until they actually were cheaper.

Coffee doesn't necessarily effect donut sales, unless stated in the question.

Henry buys a softball for $16 plus a 9% tax. Ella buys a pair of shoes for $17 plus a 9% tax. Enter the difference in the amount
Henry and Ella paid, including tax. Round your answer to the nearest cent.

Answers

Answer:

The different of the tax was 0.09 cents

Step-by-step explanation:

1. Find how much the tax was

Henry = (16/100) (9) = (0.16) (9) = $1.44

Ella = (17/100) (9) = (0.17) (9) = $1.53

2. Subtract the taxes

1.53 - 1.44 = 0.09 cent

You treat your friend to lunch. The food bill was $30.24. A 7% sales tax will be added and you want to leave a 20% tip.
a. Find the sales tax.
b. Find the tip.
c. Find the total amount you pay for lunch.

Answers

Answer:

a. $2.12

b. $6.45

c. $38.81

Step-by-step explanation:

a.

I'll convert 30.24 and 7% into fractions.

756/25 * 7/100

Cross cancel 756 and 100 (GCF is 4)

189/25 * 7/25

Convert above into a single fraction

(189 * 7)/(25 * 25)

Multiply 189 by 7, then 25 by 25.

1323/625

Divide, then round to the nearest cent

$2.1168 ≈ $2.12 in sales tax

b.

Like before, I'll convert $32.26 ($30.24 + $2.12) and 20% into fractions.

1613/50 * 1/5

Multiply 50 by 5.

1613/250

Divide, then round to the nearest cent.

$6.452 ≈ $6.45 in tip money

c.

This is probably the simplest part of the 3. Just add $30.24 + $2.12 + $6.45.

$30.24 + $2.12 + $6.45

$32.36 + $6.45

You pay a total of $38.81 for lunch.
