Answer:

x = 36

Step-by-step explanation:

The two markings mean the sides are congruent. The triangle with two congruent sides is an isosceles triangle. According to base angle theorem (only applicable to isosceles triangles), the two base angles are equal.

The angle adjacent to x is 27.

The sum of all angles in a triangle is 180

We can create an equation using parts whole postulate (PWP.)

x + 27 + 27 + 90 = 180

x + 54 + 90 = 180

x + 144 = 180

x = 36

Hope this helps :)

Answer:

you have a 25% chance of 3 and a 75% chance of greater than 1

Step-by-step explanation:

3 is only 1/4 of the cirlce meaning your chance of landing on it is 1/4 of the time which is 25%.

greater than 1 is 3/4 of the circle meaning you have a 3/4 chance wish is 75%

Answer:

0.23 per ounce

Step-by-step explanation:

2.89 / 12.4 = 0.23 per ounce

The unit rate of the crackers is $0.233 per ounce of crackers.

Unit rate is the amount of one quantity for a unit amount of the other quantity.

In other words it compares 1 unit of some quantity with different amount of another quantity.

Given that,

A certain brand of crackers costs $2.89 for 12.4 ounces.

We have to calculate the unit rate.

Cost for 12.4 ounces of the crackers = $2.89

Let the cost for 1 ounce of the crackers = x

Using the proportionality,

12.4 / 1 = 2.89 / x

Cross multiplying,

12.4 x = 2.89

Dividing both sides by 12.4,

x = 2.89 / 12.4

x = $0.233

Hence the unit rate is $0.233 per ounce of crackers.

Answer: Sam and Morgan met up at 18:00. Sam left Exeter at 10:00, and was on the road for 7 hours. I know this because 175 / 25 = 7. 10:00 + 7:00 = 17:00 meaning Sam got there at 17:00. Morgan on the other hand left at 13:00 and had an average speed of 35 mph. 175/35=5. 13:00 + 5:00 = 18:00. By 18:00 both Sam and Morgan had arrived in London thus 18:00 us your answer.

It should be noted that GDP deflator simply measures the changes in price for goods and services.

Your information is incomplete as the figures aren't given. Therefore, an overview will be given.

Gross domestic product simply means the total monetary value of the finished goods and services that are produced in a country.

The formula for calculating the GDP deflator will be:

= Nominal GDP/Real GDP × 100

Also, the formula fro calculating real GDP per capita will be:

= Real GDP/Total population

In conclusion, the real GDP is the GDP of a country that has been adjusted for inflation.

Answer:

37 is prime number

Step-by-step explanation:

To prove whether a number is a prime number, first try dividing it by 2, and see if you get a whole number. If you do, it can't be a prime number. If you don't get a whole number, next try dividing it by prime numbers: 3, 5, 7, 11 (9 is divisible by 3) and so on, always dividing by a prime number 

Answer:

37 is a prime number.

Answer:

9 dollars

Step-by-step explanation:

Solve with a system of equations

Let adult tickets be a and student tickets be s

1. 8a + 13s = 176

2. 4a + 4s = 68

3. s = 17 - a

Equation 2 is friendlier, so let's divide all the numbers by 4.

a + s = 17

Equation is s = 17 - a

Substitute s in equation 1

8a + 13(17-a) = 176

8a + 221  - 13a = 176

221 - 5a = 176

5a = 45

a = 9

The price of an adult ticket is 9 dollars
