15. In a parallelogram ABCD, AB = 7.2 cm and the perpendicular from C on AB is 4.5 cm find its area.​

Answers

Answer:

32.40cm²

Step-by-step explanation:

Given the parallelogram ABCD ;

side AB is always Parallel to CD, hence ;

AB = CD = 7.2cm

Perpendicular from C on AB is the height of the parallelogram = 4.5cm

Area of a parallelogram : base * height

Area of a parallelogram = length base * height

Area of a parallelogram = 7.2 cm * 4.5cm

Area of parallelogram = 32.40cm²

The perimeter of a triangle is 22cm. If one of the sides is 9cm, find the other sides if the area of the triangle is 20.976cm2​

Answers

Answer:

6 cm and 7 cm

Step-by-step explanation:

Given

A triangle with:

P = 22 cmA = 20.976 cm²a = 9 cmTo find Other sides of the triangleSolution

Let the missing sides be b and c

The perimeter is

P = a + b + c

Substitute known values

22 = 9 + b + cb + c = 13c = 13 - b

Use Heron's formula for the area:

A = √s(s-a)(s-b)s-c), where s is half-perimeters = 22/2 = 11

Substitute s, a and c and solve for b:

√11(11 - 9)(11 - b)(11 - c) = 20.976√11*2(11 - b) (11 - 13 + b) = 20.976√22(11 - b)(b - 2) = 20.976

Square both sides

22(11 - b)(b - 2) = 20.976²22(11 - b)(b - 2) ≈ 440(11 - b)(b - 2) = 20 13b - b² - 22 = 20b² - 13b + 42 = 0b = (13 ± √13² - 4(42))/2b = (13± 1)/2b = 6, b = 7

Find c:

c = 13 - bc = 6, c = 7

So missing sides are 6 cm and 7 cm

Pete has 3 dollars less than what Linda has. If together has 81 dollars how much does each person have?

Answers

Answer:

Pete: 39, Linda: 42

Step-by-step explanation:

Suppose Pete has x dollars. If he has 3 dollars less than Linda, then Linda has 3+x dollars. Together, they have 81 dollars:

x+3+x=81

2x+3=81

2x=78

x=39

Since Pete has x dollars, and x=39, he has $39.

Linda has 3+x, which is 39+3 = $42

Jim was thinking of a number. Jim halves it and gets an answer of 3.4. What was the original number?

Answers

Answer:

6.8

Step-by-step explanation:

To tackle these types of questions, you essentially have to 'undo' or ' reverse' the calculation/s that is being done in the question.

In the question, the calculation that is being done is 'halfing' or 'dividing by 2'.

So to find the original number you have to do the opposite - double or 'multiply by 2'

Therefore

3.4 x 2 = 6.8

Mike bought a box of 12 golf balls for $18. Solve the equation 12x=$18 to find the price of each golf ball. $1 25, $1 50, $1 75 are the options. Choose one and please show work.

Answers

Answer:

The price of each golf is $ 1.50

Step-by-step explanation:

Given;

Price of 12 golf balls = $18

Let the price of 1 golf ball = x

Price of 12 golf balls = 12x

But the total price of the 12 golf balls = $18

Thus, 12x = $18

x = $18 / 12

x = $ 1.50

Therefore, the price of each golf is $ 1.50

i need to reduce the radical 252

Answers

6x the square root of 7

Answer:

√252 = 6√7

Step-by-step explanation:

Double Prime Factor Method

The Double Prime Factor Method uses the prime factors of 252 to simplify the square root of 252 to its simplest form possible. This is how to calculate A and B using this method:

A = Multiply all the double prime factors (pairs) of 252 and then take the square root of that product. The prime factors that multiply together to make 252 are 2 x 2 x 3 x 3 x 7. When we strip out the pairs only, we get 2 x 2 x 3 x 3 = 36 and the square root of 36 is 6. Therefore, A equals 6.

B = Divide 252 by the number (A) squared. 6 squared is 36 and 252 divided by 36 is 7. Therefore, B equals 7.

Once again we have A and B and can get our answer to 252 in its simplest radical form as follows:

√252 = A√B

√252 = 6√7
