ABCD is a rectangle and AC and BD are its diagonals. If AC = 10 cm, then BD is?

A. 10 cm
B. 5 cm
C. 15 cm
Or D. 20 cm

Lemme know, take ur timeee

Answers

Answer 1

Answer:

A. 10 cm

Step-by-step explanation:

In a right angled triangle, a² + b² = c² where c is the diagonal or hypotenuse. If you split a rectangle diagonally into two right angle triangles, the a and b of both triangles would be the same length. Therefore, the c or diagonals would also be the same length - 10 cm.

Hope this helps!

Michael started a savings account. After 5 weeks, he had $340 dollars and after 9
weeks, he had $580. What is the rate of change of money in his savings account per
week?

Answers

Answer:

$60.00 in his savings account per week

Step-by-step explanation:

First, we can convert the information given into points so we can more easily find the rate of change, or slope:

(5, 340) and (9, 580)

Then, we can subtract the y-values and x-values of both, then divide those differences, to find the slope. Remember that the change in y goes on top of the division problem and the change in x goes on the bottom of the division problem:

(580-340)/(9-5) = 240/4 = 60

So, $60 in his savings account per week.

Answer:

he saves 18.45 dollars in each week

Answer:

1920 cubic centimeters

Step-by-step explanation:

If you recall the formula to find volume, it is V=Bh (Bh stands for area of the base times the height). First, multiply 14, 8, and 10 together, to get 1120, the volume of the first figure. To find the volume of the second figure, do the same: multiply 10, 10, and 8 together to get 800. Finally, add the two volumes together to get the volume of the figure, 1920 cubic centimeters.
