Answer 1

Answer:

[tex] \huge \: x = 7 {0}^{o} \\ \: \huge \: y = 3 {0}^{o} \\ \huge z = {20}^{o} [/tex]

Step-by-step explanation:

to understand thisyou need to know about:trianglesequationPEMDAStips and formulas:a straight line contains 180°a triangle contains 180°let's solve:

equation for x

according to the question

110°+x=180°

x=180°-110°

x=70°

equation for y

according to the question

[tex]11 {0}^{o} + {40}^{o} + y = 18 {0}^{o} [/tex]

[tex]15 {0}^{o} + y = 180^{o} [/tex]

[tex]y = 18 {0}^{o} - 15 {0}^{o} [/tex]

[tex]y = 3 {0}^{o} [/tex]

equation for z

according to the question

90°+x+z=180°

90°+70°+z=180° (since x=70°)

160°+z=180°

z=180°-160°

z=20°

Answer 2

Answer:

X= 70

Z= 20

y= 30°

Step-by-step explanation:

Finding X:

Sum of angle in a straight line is 180

Therefore X = 180-110

Finding z:

Sum of angle in triangle is 180, and it’s a right angled triangle (90°)

Z= 180-(x+90)

Z= 180-( 70+90)

Finding y, look at the big triangle ABC:

There’s a right angle and <C is 40°,

Therefore <B is 180-(40+90)= 50°

<B= y + z

50° = 20° + y

y= 30°

Savannah is deciding between two parking garages. Garage A chargers an initial fee of $9 to park plus $1.50 per hour

Answers

Answer: 4 hours

Step-by-step explanation:

Assume x is the number of hours taken.

Garage A would therefore charge a total of:

= $9 + $1.50 * x

= 9 + 1.50x

Garage B would charge:

= $5 + $2.50 * x

= 5 + 2.50x

To find the number of hours it would take for them to be the same, equate both equations:

9 + 1.50x = 5 + 2.50x

9 - 5 = 2.50x - 1.50x

4 = 1x

x = 4 hours

That cost would be:

= 9 + 1.50 * 4

= 9 + 6

= $15

Step-by-step explanation:

write an equation of the given line that passes through the given point and has the given slope m
(5,1);m=2

Answers

Answer:

y = 2x - 9

Step-by-step explanation:

Use slope intercept form, y = mx + b

Plug in the slope, x, and y, then solve for b:

y = mx + b

1 = 2(5) + b

1 = 10 + b

-9 = b

Then, plug in b and the slope into y = mx + b

y = mx + b

y = 2x - 9

So, the equation of the line is y = 2x - 9

Answer:

Step-by-step explanation:

y=mx+b, m=2

y=2x+b, using point (5,1)

1=2(5)+b

b=-9

y=2x-9

A student is 1.75m tall and is trying out for the football team. He kicks the football straight up
in the air from his outstretched arms at a height of 1 m. If the ball hits him on the head on the
way back down 3 seconds later, what was the football's initial velocity?

Answers

Answer: see below

Step-by-step explanation: Initial velocity = terminal velocity. At the top of travel, the velocity is 0 as the ball is motionless. Then it travels 3 seconds (due to gravity). Grav is 9.8m/sec squared. So 1st second = 9.8m. 2nd second is 2x9.8m. 3rd second is 3x9.8m = 29.4 m/sec.

Profit is the difference between revenue and cost. The revenue, in dollars, of a company that manufactures televisions can be modeled by the polynomial 3x2 + 180x. The cost, in dollars, of producing the televisions can be modeled by 3x2 – 160x + 300. The variable x is the number of televisions sold.

If 150 televisions are sold, what is the profit?

$2,700
$6,000
$50,700
$51,300

Answers

Answer: $50,700 is the profit

If 150 televisions are sold, the profit is $50,700.

What is profit?

Profit is the total revenue less the total cost.

Profit = total revenue - total cost

What is profit?

Profit = (3x^2 + 180x) - (3x2 – 160x + 300)

Profit = (3 x 150^2 + 180 x 150) - (3 x 150^2 - 160x 150 + 300)

27,000 + 24,000 - 300

Profit = $50,700

Black bears and Grizzly bears

9 out of 12 = black bears ; Hence, 3 are grizzled

For the model:

For a bear population of Number x

Total bear population = black bear, x + grizzled bear, y

Proportion of black bear = 9/ 12 = 0.75

Grizzled bear = 1 - 0.75 = 0.25

Total bear population , Z= 0.75x + 0.25y

Devin bought a new car

20% off. Determine the
original price of the car.

Answers

Answer:

$23780

Step-by-step explanation:

Given data

Let the original price be x

discount= 20%

price= $19,024

so that

20/100*x=x-19,024

0.2x= x-19,024

19,024=x-0.2x

19,024=0.8x

x= 19,024/0.8

x=23780

Hence the original price is $23780

What is decimal?

Decimals are a set of numbers lying between integers on a number line. They are just another way to represent fractions in mathematics. With the help of decimals, we can write more precise values of measurable quantities like length, weight, distance, money, etc. The numbers to the left of the decimal point are the integers or whole numbers and the numbers to the right of the decimal point are decimal fractions. If we go right from ones place, the next place will be (1/10) times smaller, which will be (1/10)th or tenth place value.
