The estimated answer to a multiplication problem is 800,000. Which of the following expressions could result in this answer? Exp
EastWind [94]

Answer:

8,146 x 121

Step-by-step explanation:

This is a problem in which you need to measure your understading of "orders of magnitude."

If the estimated answer is 800000 that means that we are looking at a multiplication in the "order of" 8*10^5

You need to look at the "orders of magnitude" of the things you're multiplying. In the first case, we have 8146*12 that would be "of the order of" 8*10^3 times 10^1. So the whole multiplication would "of the order of" 8*10^4 or near 80000

The correct answer, 8,146 x 121, is because it's "of the order of" 8*10^3 times 10^2 and the gives us the 8*10^5 we need.

Help me get the anwser to this Equation
Mariana [72]

Answer:

The answer depends on x.value

Step-by-step explanation:

I. It's linear equation

          y = mx + b

when y is output, x is input, m is slope and b is addition

   So if x = -1

          y = -4/3(-1) - 2

             = 4/3 - 2

             = (4-6)/3

           y = -2/3

   It will be something like this (-1, -2/3) when -1 is x.value, -2/3 is y.value        

You can given x.value be anything like 0, 1, 2, 3 the graph will be like this

(Picture is only example)

Rosa's test scores are 78, 92, 88, and 89. What must she score on her next test to have an average of 90? A) 95 B) 97 C) 99 D) 1
Morgarella [4.7K]

Answer: D

<u>Step-by-step explanation:</u>

Let x represent the score on her next test

\frac{78 + 92 + 88 + 89 + x}{5} = 90

(5)\frac{78 + 92 + 88 + 89 + x}{5} = (5)90

78 + 92 + 88 + 89 + x = 5(90)

                      347 + x = 450

                    <u> -347      </u>   <u>-347 </u>

                                x = 103
