Answers

Answer:

A = 4 cm^2

Step-by-step explanation:

The area of a triangle is

A = 1/2 b*h

The base is 4 and the height is 2

A = 1/2 ( 4*2)

A = 1/2*8

A = 4 cm^2

Answer:

Step-by-step explanation:

A = BH/2

or Area = Base multiplied by Hieght divided by 2.

(b)4 x (h)2 = 8

8/2 = 4

The fountain contains 20 pennies and 9 dimes. A coin is randomly taken and not replaced. A second coin is randomly taken. What is the probability that both coins are pennies?

Answers

Well, the first coin has chance $(20)/(29)$ to be a penny. When it is a penny, the only valid case (the other case gives 0 for the multiplications later, so it is ignored) gives $(19)/(28)$ chance for the second one to be a penny. The result is $(20*19)/(29*28)$ , which is $(95)/(203)$ , or about 46.80% (rounded to the first 2 decimals)

Answer:

9 dimes

Answer:

the answer to this would be 256.

Step-by-step explanation:

before explaining this,

- negative x negative = positive

- positive x positive = positive

- negative x positive = negative

- positive x negative = negative

this would be because -2 x -2 it equals 4. then, we multiply 4 x -2 and we get -8, then we multiply -8 x -2 and we get 16, then we keep doing the same thing until we get the answer/ used all the -2's.

1. -2 x -2 = 4

2. 4 x -2 = -8

3. -8 x -2 = 16

4. 16 x -2 = -32

5. -32 x -2 = 64

6. 64 x -2 = -128

7. -128 x -2 = 256

The sum of three consecutive integers is 267 what is the largest integer

Answers

Well 88 + 89 + 90 = 267. So the largest integer is 90.

If we cal lthe first number 'n' then we know that the numbers are n, n+1 and n+2 and we know the sum:
$n+(n+1)+(n+2)=267$
therefore:
$3n+3=267$
$3n=264$
$n=88$

The numbers are 88,89,90, the largest of which is 90.

To check: 88+89+90=267. Checks.
