Answer:

11

Step-by-step explanation:

At least one means 1  being 4 or 2 of them being 4 this in case.

You could set a table:

1| 1  2  3  4  5   6

2| 1  2  3  4  5   6

3| 1  2  3   4  5   6

4| 1  2  3   4  5   6

5| 1  2  3   4   5  6

6| 1  2  3   4   5  6

There are 11 different ways to get at least one 4.

See this:

(first dice, second dice)

(1,4)

(2,4)

(3,4)

(4,4)

(4,5)

(4,6)

But there is also

(4,1)

(4,2)

(4,3)

(4,4) already counted earlier so don't count this one again

(4,5)

(4,6)

The area of a triangular block is 49 square inches. If the base of the triangle is twice the height, how long are the base and t
andrezito [222]
1) Formula: area = height * base / 2

2) Call x the height:

height = x

base = 2x

3) State the equation:

(x)(2x) = 49 in^2

4) Solve the equation:

2x^2 = 49 in^s

x^2 = (49/2) in^2

x = √(49/2) in

x = 7√2 / 2 in = 3.5 √2 in

5) Solution:

height = 3.5 √2 in and base = 7√2 in

6) Verification: area = (7√2 in) (3.5√2 in) = 49 in^2

Answer: height = 3.5√2 in and base = 7√2 in.

If the exponent is 3 and the base is 2 whats the simplified expression
Rom4ik [11]
If the base is 2 and the exponent is the the expression would look like this → 2³. In order to simplify it, you have to multiply the base number by the number of the exponent. 

2×2×2=8
Therefore, the simplified expression would be 8.

I hope this helped.

\sf \underline{Answer:}

Pick any value for x, like x = 0, plug it into the equation, and get the value for y. For x = 0,

2(0) + y = 5

y = 5

The ordered pair is (0,5). Find other ordered pairs using the same reasoning.
