Answer: (400 • 600) + 40 = 240,040

Step-by-step explanation:

Remember: PEMDAS = Parentheses, Exponents, Multiply, Divide, Add, & Subtract (always goes in this order)

(400 • 600) + 40 = ← Given expression

240,000 + 40 =

↑

What happens when you solve what's in the parentheses.

240,040 ← What happens after you add the numbers.

Can someone actually answer this question pls its my 3rd time posting it and ill ive gotten was wrong or answers that make no se

Answer:

(-2+-5) equals -7.

Because the signs are the same, we dont change it.

(3+5) equals 8. Same like the other equation, the signs are the same so we do not change it.

Now we do (-7+8) The answer will be 1. Lets use a little graph since its hard to explain.

-8 -7 -6 -5 -4 -3 -2 -1 0 1 2 3 4 5 6 7 8

Mark -7 anyway you want. (Circle it, draw a line under it, what ever you want.)

Now Move the line 8 times.

When you do that your line will stop at 1.

And thats how you do it.

What is the volume of a cone with diameter 21 m and height 4 m?

natima [27]

For this case we have by definition, that the volume of a cone is given by:

$V = \frac {1} {3} * \pi * r ^ 2 * h$

Where:

A: It is the cone radius

h: It's the height

They tell us that the diameter is 21 m, then the radius is half the diameter, that is: 10.5m. The height is 4m. Substituting the data:

$V = \frac {1} {3} * \pi * (10.5) ^ 2 * 4\\V = \frac {1} {3} * \pi * 110.25 * 4\\V = 147 \pi$ .

Finally, the volume of the cube is $147 \pi \ m ^ 3$

Use a normal approximation to find the probability of the indicated number of voters. In this case assume that 150 eligible vote

alexdok [17]

The number of people who voted follows a binomial distribution with probability of having voted $p=0.22$ and $n=150$ subjects, which means the approximating normal distribution should have mean $np=33$ and standard deviation $\sqrt{np(1-p)}\approx5.07$ .

With the continuity correction, you have

$\mathbb P(X$
