HELP ASAP 10 POINTS TO BRAINLIEST

Mathematics
1 answer:
Brilliant_brown [7]3 years ago
6 0

Answer:

15%

Step-by-step explanation:

The cost of 2 adults and 2 children without the discount is

2 adults = 2 (55) = 110

2 children = 2 (45) = 90

Total cost = 110+90 = 200

The original price is 200 and the new price is 170

Percentage discount = (Original price - new price)/ original price * 100%

                                     = (200-170)/200 * 100%

                                     = 30/200 * 100%

                                     = .15 * 100%

                                     = 15%

(9,4) and (5,-3) find the slope please !!!!
Crank

Answer:

I think that the slope would = 1.75 I believe

Step-by-step explanation:

How to find slope (Other Example)

Identify the coordinates (x₁,y₁)and(x₂,y₂). We will use the formula to calculate the slope of the line passing through the points (3,8) and (-2, 10).

Input the values into the formula. This gives us (10 - 8)/(-2 - 3).

Subtract the values in parentheses to get 2/(-5).

Simplify the fraction to get the slope of -2/5.

Check your result using the slope calculator.

Taylor opened a savings account with $425. After 2 years, the total interest earned was $10.20. What was the annual interest rat
storchak [24]

Answer:

R = 1.2%

Step-by-step explanation:

<u>Given the following data;</u>

Principal = 425

Time = 2

Simple interest = 10.20

To find the annual interest rate;

Mathematically, simple interest is calculated using this formula;

S.I = \frac {PRT}{100}

Where;

  • S.I is simple interest.
  • P is the principal.
  • R is the interest rate.
  • T is the time.

Substituting into the equation, we have;

10.20 = \frac {425*R*2}{100}

10.20 = \frac {850R}{100}

Cross-multiplying, we have;

1020 = 850R

R = \frac {1020}{850}

<em>R = 1.2%</em>

<em>Therefore, the annual interest rate is 1.2 percent. </em>

Find a.b.c if one of the angles is 150
Zepler [3.9K]
Triangle has 180 degrees
1 side=180
Then 180-150= 30 degrees
30/2 (for the other two sides)= 15
So, 150 degrees, 15 degrees and 15 degrees.
So it’s probably an isosceles triangle as the two bottom angles are the same number of degrees

Hope this helps :)
