Answer:

62.8

In a triangle the sum of interior angles is always 180 degree. So by appropriate equation we get the result as

angle C = 90 -27.2=62.8

Yvonne's car with an 11-gallon gas tank gets an average of 32 miles per gallon. She travels 12 hours at an average speed of 64 m
n200080 [17]

Answer:

$78

Step-by-step explanation:

Here we have to find total distance first then find amount of gasoline used based on distance traveled by car in one gallon.

_____________________________________________

Given

time = 12 hours

speed = 64 miles per hour

we know distance = speed * time

distance = 12*64 = 768 miles.

Thus, car ran 768 miles.

given that car gets an average of 32 miles per gallon.

It means in one gallon gasoline car travels 32 miles.

let the gallons used be x

in 1 gallon gasoline car travels 32 miles.

in 1*x gallon gasoline car travels 32*x miles = 32x

Thus, 32x should be equal to 768 miles as car traveled that much only

32x = 768 miles

x = 768/32 = 24

Thus, gallons of gasoline used is 24.

Cost of 1 gallon gasoline = $3.25

since, gallons found is 24, we multiply lHS and RHS by 24

Cost of 1 *24= 24 gallon gasoline = $3.25*24 = $78

Thus,

cost of 24 gallon is $78 which will be the gasoline cost for the trip.

Which of the following are the zeros of the function y= 3(x-a)(x+b) in terms of a and b? ​
frosja888 [35]

The correct answer is option 2.

3 = 0

x - a = 0

x = a

x + b = 0

x = -b

We do not multiply any of these values by 3 because in a way, 3 is acting as another "zero" of the equation. Though, as shown above, it does not equal 0, it still does not apply to any of the other equations solved above.

Hope this helps!! :)

Answer:

Area = 34.2cm^2

Step-by-step explanation:

Let the three sides be a, b and c respectively.

Such that:

a = 8

b = 9

c= 10

Required

Determine the area

This is calculated as:

Area = \sqrt{s(s-a)(s-b)(s-c)

Where

s = \frac{1}{2}(a + b + c)

Substitute values for a, b and c

s = \frac{1}{2}(8 + 9 + 10)

s = \frac{1}{2}(27)

s = 13.5

Substitute values for a, b, c and s in

Area = \sqrt{s(s-a)(s-b)(s-c)

Area = \sqrt{13.5 * (13.5 - 8)* (13.5 - 9)* (13.5 - 10)

Area = \sqrt{13.5 * 5.5* 4.5* 3.5

Area = \sqrt{1169.4375

Area = 34.2 -- Approximated
