Answer:

140.74

Step-by-step explanation:

1.area of right triangle

1/2*b*h=1/2*20*18=180

2.area of semi circle

1/2*pi*r^2=1/2*pi*5^2=39.26

r= d/2

180-39.26=140.74

Answer: See explanation

Step-by-step explanation:

From the question, we are informed that Michelle buys a car that costs $15,000 and that she makes a down payment of $5,000 and later pays $3000 in the next payment.

To get the equation that can be used to find the amount she still owes, C, of the car, we will have to deduct the amount that she has paid from the cost of the car. This will be:

C = 15000 - 5000 - 3000

C = 15000 - 8000

Therefore solving the equation further, the amount left to pay will be:

C = 15000 - 8000

C = 7000

Answer:

(2) 23x + 250

Step-by-step explanation:

We are given that

Company charges  for one-time set up=$250

Charge for each printed jersey=$23

x=Number of jerseys for team

We have to find the expression which represents the total cost of x number of jerseys for the team.

Total cost of x jerseys printing=[tex]23\times x[/tex]

Total cost of x jerseys printing[tex]=23x[/tex]

Therefore,

Total cost of x number of jerseys for the team=250+23x

Hence, option (2) is true.

(2) 23x + 250

Answer: 4°F

Step-by-step explanation:

From the question, we are informed that temperature at 5:30 a.m was –4°F and that eight hours later, at 2:30 p.m, the temperature is the opposite of –4°F.

The temperature at 2:30 will be 4°F since the opposite of -4 is +4. Also since there's an interval of 8 hours, it's likely that the temperature increased by 1° for every hour. In 8 hours, it'll have increased by 8°, therefore the temperature will then be:

= -4 + 8

= 4°F

Answer:

x=2 y=1

Step-by-step explanation:

Answer:

y=2x+12

Step-by-step explanation:

y-2=2(x-(-5))

y-2=2(x+5)

y-2=2x+10

y=2x+12

Answer:

[tex]\frac{35}{54}[/tex]

Step-by-step explanation:

When multiplying two fractions, you multiply across always. We have two fractions :

7/9 and 5/6

So multiply across :

[tex]\frac{7 * 5}{9 * 6}[/tex]

[tex]\frac{35}{54}[/tex]

Answer:

  y = -4x +9

Step-by-step explanation:

The same slope-intercept equation can be used, but with a different y-intercept. That new y-intercept can be found from the given point (x, y) using the formula ...

  b = y -mx

  b = 5 -(-4)(1) = 9

So, the equation with the new y-intercept is ...

  y = -4x +9

Answer:

Youu can call the breadth x and then, as the length is two times the breadth, it would be 2x.

So now when we call x to the breadth and 2x to the length we can do an equation, as we know the sum of the four sides is 300 meters, so

2x + 2x + x + x = 300

6x = 300

x = 300/6 = 50

We know that the breadth is 50m, and, the length, which is twice the breadth, would be 100m in this exercise.

SO in this case, the breadth is 50 meters and the length is 100 meters..

Let me know if you'd like me to clarify something. Good luck

Answer:

your learning about slopes too :(

Step-by-step explanation:

Slope = change in y over change in x.

Slope = (2-1) / (3-8) = 1/-5 = -1/5

The answer is -1/5

Step-by-step explanation:

BE and CF are two equal altitudes of triangle ABC using RHS congruence rule prove that triangle ABC is isosceles.

Solution:

A triangle is a polygon with three sides and three angles. Types of triangles are right angled triangle, scalene triangle, equilateral triangle and isosceles triangle.

The RHS congruence rule states that if the hypotenuse and one leg of one triangle is equal to the hypotenuse and leg of another triangle; then the two triangles are equal. Two triangles are equal if they have three equal angles and three equal sides.

We have right angle triangles BEC and BFC

BE = CF (given)

CB = BC (both triangles have the same hypotenuse)

Hence ΔBEC = ΔBFC (RHS congruence rule)

Therefore; ∠BCE = ∠FBC (congruence theorem)

Since two angles of triangle ABC are equal (∠B = ∠C), therefore triangle ABC is an isosceles triangle and AB = AC

C

Answer:

1.8 meters

Step-by-step explanation:

7.2÷4= 1.8

Answer:

1.8 m

Step-by-step explanation:

let side be 'a'.

perimiter of a square = 4(a)

7.2 = 4(a)

7.2/4 = a

therefore, a = 1.8 m.
