Find the area of the triangle. Figure is not drawn to scale. Show your work. (Image attached)Thanks so much in advance !! :))

Answers

Answer 1

Answer:

Answer: $13.8cm^2$

Step-by-step explanation:

The area of a triangle can be calculated with the formula:

$A_((triangle))=(b*h)/(2)$

The base of the triangle is "b" and the height of the triangle is "h",

In the figure you can observe that the base and the height of the triangle are:

$b=6.9cm\nh=4cm$

Knowing these values, you can substitute them into $A_((triangle))=(b*h)/(2)$ .

Therefore, the area of the triangle is:

$A_((triangle))=((6.9cm)(4cm))/(2)$

$A_((triangle))=13.8cm^2$

Jason is saving up for a skateboard and helmet. The skateboard is 45.50 with tax and the helmet is 18.25 with tax. He earned 1/3 of the money by mowing lawns and the rest by babysitting. How much did jason earn with babysitting

Answers

Answer:

2/3 of the money, $42.50

Step-by-step explanation:

The total Jason is saving is ...

$45.50 +18.25 = $63.75

If 1/3 was earned by mowing, the remaining 2/3 was earned by babysitting. Two thirds of the amount is ...

(2/3) × $63.75 = $42.50

Jason earned $42.50 by babysitting.

Compare and contrast the perpendicular bisectors and angle bisectors of a triangle. How are they alike? How are they different?

Answers

They are alike because they both divide something.. They are different because one perpendicular bisector divides one side of the triangle into two equal lengths at a 90 degree angle. So if there's is three perpendicular bisectors, then it splits all three sides the triangles into equal lengths. Angle bisectors splits an angle of a triangle into two even degrees.

Answer:

Step-by-step explanation:

The perpendicular bisectors and angle bisectors are alike in one manners that they both divide the entities they are drawn at.

Perpendicular bisector bisect the sides of triangle in two equal halves and angle bisectors divides the angles to which they are drawn in two equal halves.

The difference is that ,

the point at which perpendicular bisectors meet, is the center of circumcircle which is drawn through the vertices of triangle

the point at which angle bisectors are met, is called the incenter , and is the center of incircle inscribed in a triangle touching its three sides.

Find a4 in the sequence given by {a1=-3 and an=an-1+7

Answers

Answer:

a4 = -12

Step-by-step explanation:

Which shows 232 − 172 being evaluated using the difference of perfect squares method?232 − 172 = (529 + 289)(529 − 289) = 196,320
232 − 172 = 529 − 289 = 240
232 − 172 = (23 + 17)(23 − 17) = (40)(6) = 240
232 − 172 = (23 − 17)2 = (6)2 = 36

Answers

difference of perfect squares is a² - b² = (a+b)(a-b)

Here, we can let 23 = a and 17 = b, so using this method, we have
23² - 17² = (23+17)(23-17) = 40 × 6 = 240

So third option is correct.

Answer:

Your answer is 23^2 − 17^2 = (23 + 17)(23 − 17) = (40)(6) = 240, or C on your answer sheet.

Step-by-step explanation:

Lets begin!

So when a binomial is composed of two perfect squares separated by a subtraction symbol, a certain method called the difference of perfect squares can be used. The difference of perfect squares method can be done by multiplying the sum and difference of the two square roots.

So, to solve:

23^2 - 17^2 = (23 + 17)(23-17) = (40)(6) = 240

Thus being your answer.
