12. The side lengths of three triangles are shown.
Which of the triangles are right triangles?

Answer:

502.4ft^3

Step-by-step explanation:

Given data

Height= 10ft

radius= 4 ft

Hence the volume for the cylinder can be gotten as

v= πr^2h

v= 3.14*4^2*10

v=3.14*16*10

v=502.4ft^3

Therefore the volume of the cylinder is 502.4ft^3

Step-by-step explanation:

Answer:

x=15

Step-by-step explanation:

Like solving all Algebra equations, it is very important to make sure that the variables (In this case x) are on one side and the numbers are on the other side.

85-3x=40

First, let's subtract 40 on both sides

45-3x=0

Add 3x to both sides

45=3x

Let's divide both side by 3

And we get...

x=15

Answer: 7 I think

Step-by-step explanation:

Answer:

Step-by-step explanation:

Here the function is y = 5x.

If x = -2, y = 5(-2) = -10;

If x = 0, y = 5(0) = 0; and

If x = 9, y = 5(9) = 45

And so on

Answer:

y=2/5x+8/5

Step-by-step explanation:

so say you plot a graph of rain against the hours the gradient would be the rate of change and the information given as your points and the gradient

now to get an equation of a straight line use one of your points eg(1,2) and the gradient or rate of change mine was 0.4

Answer:

a) 3/13

b) 1/2

Step-by-step explanation:

a) In a deck of 52 cards there are 4 Kings, 4 Queens and 4 jacks. So the probability of drawing those cards is (4+4+4)/52 = 12/52 = 3/13.

b) 1/2 because the numbers greater than 3 on a dice is 4, 5, and 6 which is half of the available options.

Answer:

8

Step-by-step explanation:

10-2 = 8

The range of a set of data is the difference between the highest and lowest values in the set. To find the range, first, order the data from least to greatest. Then subtract the smallest value from the largest value in the set.

Answer:

14.2604

Step-by-step explanation:

this is because 22% as a decimal would be 0.22, and since this is out of 64.82, you have to multiply 0.22 by 68.82

Step-by-step explanation:

Answer:

The probability of landing on 8 twice is 1/64

Step-by-step explanation:

If you spin the spinner once, there are 8 possibilities each time (1-8). The possibility of landing on the number 8 is 1 of these 8 possibilities. Its probability is therefore 1/8

Each spin is independent. In other words, the spins do not affect each other. The number you land on during the first spin does not impact the second spin's number. The probability of landing on 8 the second time is the same as the first time: 1/8

Because the two events are independent, we find the probability of them both occurring by multiplying them together.

1/8 times 1/8= 1/64

hope this helps:)

Step-by-step explanation:

The height of logo is 7.6 cm.

An ellipse is a closed curve, the intersection of a right circular cone and a plane that is not parallel to the base, the axis, or an element of the cone.

Given:

x²/64 + y²/14.44=1

We know

x²/a² + y²/b² =1

On comparing

a²=64

and, b²=14.44

Also, a=8 and b= 3.8

So, length of logo will be = 2h

=2* 3.8

=7.6 cm

Answer:

I = $ 1,080.00

Step-by-step explanation:

Equation:

I = Prt

Calculation:

First, converting R percent to r a decimal

r = R/100 = 3.6%/100 = 0.036 per year,

then, solving our equation

I = 7500 × 0.036 × 4 = 1080

I = $ 1,080.00

The simple interest accumulated

on a principal of $ 7,500.00

at a rate of 3.6% per year

for 4 years is $ 1,080.00.
