Answer:

Angles in a quadrilateral add up to 360°.

[tex]90 + 3x + x + 20 + 2x + 10 = 360\\ 90 + 20 + 10 + 3x + x + 2x = 330\\ 120 + 6x = 360 \\ 6x = 360 - 120 \\ 6x = 240 \\ x = \frac{240}{6} \\ x = 40[/tex]

[tex]3x = 3 \times 40 = 120 \\ [/tex]

[tex]x + 20 = 40 + 20 = 60[/tex]

[tex]2x + 10 = 2 \times 40 + 10 = 80 + 10 = 90[/tex]

Difference between largest & smallest angles =

[tex]120 - 60 \\ = 60[/tex]

60 is the difference the largest & the smallest angle.

If 9/10 is multiplied by 8/9 , will the product be greater than either of the two factors?

Find the value of sin^-1(4pi/5)

Answers

Answer:

No value because 4π/5 exceeds the domain

Step-by-step explanation:

The domain and range of sin^-1(x) is a domain of [-1,1] and a range of [-π/2,π/2]

Since 4π/5>1, this exceeds the domain and therefore has no value.

Write two algebraic equations, let represent Alyssa’s age in years and represent Brittany’s age in years.
Tysm if u do this <3

Answers

Answer:

Brittany is 15 years old

Step-by-step explanation:

The way we get the answer is by getting the age of Alyssa 45-15=30 as, Jazmin is 15 years older than Alyssa and then we can see that Alyssa is twice as old as Brittany so we divide Alyssa's age by two. 30÷2=15 and we get Brittany's age which is 15 years old.

she is 15 years old ( Brittany)

Answers

Answer:

Let x = the number of minutes of calls

For Plan 1, we know that the monthly charge is 8 + 0.18x

For Plan 2, the monthly charge is 23 + 0.14x

To determine when the cost of the two plans will be equal, we set up the following equation:

8 + 0.18x = 23 + 0.14x

Find the distance between the two points rounding to the nearest tenth (In decimal).

Answers

Answer:

approximately 8.9

Step-by-step explanation:

Regard (3, -2) and (7, 6) as the two acute angle vertices of a right triangle. The horizontal leg of this triangle has the length (7 - 3) = 4, and the vertical leg 6 - (-2) = 8.

Apply the Pythagorean Theorem to find the length of the diagonal connecting these two points. This length is the distance between the two points:

d = √(4² + 8²) = √(16 + 64) = √80 + √16√5 = 4√5, or approximately 8.9

Answers

Answer:

a) 1000+0.05x ≥2200

b) x=24000

Step-by-step explanation:

a) So we know that Nadia for certain gets paid $1000 each month. That is a concrete amount that doesn't change, so the variable (x) would be placed on the 5% she earns from sales. We don't know how much she sells each month because it varies, so that will be represented by the X. Her goal is to raise NO LESS than $2200, which means the amount she earns from sales has to be greater than or equal to $2200.

b) From here just solve the equation for X:

Mr. Sweeney's car can travel 195 miles on 10 gallons of gas. How far
can Mr. Sweeney travel if he buys 18 gallons of gas?
I

Answers

Answer:

Miles in 10 gallons = 195

Miles in 1 gallon = 195/10 = 19.5

Miles in 18 gallons = 19.5 × 18 = 351 miles.

Answer:

Miles travelled by the car on 10 gallons of gas = 195 miles

Miles travelled by the car in 1 gallon of gas = 195 ÷ 10 = 19.5 miles

Miles travelled by the car in 18 gallons of gas = 19.5 × 18 = 351 miles.
