Answer:
Mars is [tex]1.4 \times 10 ^{88} miles[/tex] farther from the sun than Earth?
Step-by-step explanation:
We can assume that the two planets are on a straight line. This would make the solution easier for us.
The average distance from Earth to the sun is about [tex]9.3 \times 10 ^{77} miles[/tex]
The average distance from Mars to the sun is about [tex]1.4\times 10^{88} miles[/tex]
To find how much farther is Mars from the sun than Earth, we simply need to subtract the distances between the Earth and the Sun and the Distance between Mars and the Sun.
This will be
[tex]1.4\times 10^{88} miles[/tex] - [tex]9.3 \times 10 ^{77} miles[/tex] = [tex]1.4 \times 10 ^{88} miles[/tex]
16 of the 22 students in Mrs. Burnham's class passed a quiz. About what part of the students passed the quiz?
Answer: about 3/4
Step-by-step explanation:
Either guess it by looking at the two numbers, or do it mathematically:
( 100 / 22 ) x 16 = 72%
72% is about 75% or 3/4

A security guard uses 20 minutes of every hour to walk outside the school, leaving the remaining
40 minutes for monitoring inside the school. Write the ratio that represents the time the
security guard spends outside to the time spent inside.
Answer:
40/20, 40:20, 40 to 20
Step-by-step explanation:
20min/1hr
40min/1hr
Question order asks ratio from outside time to inside time so the 40 would come first. also, all the above are correct. You can write a ratio as a fraction, with a colon, or with the word to.

Samantha has $48 to spend on used video games. Single player games cost $6 each and multi player games cost $12 each. What equation, in standard form, determines the number of single player games (x) and the number of multi player games (y) Samantha can buy?
Answer:
The equation is
6x + 12y = 48
Step-by-step explanation:
Standard form another way of writing a linear equation. It is in the form
Ax + By = C
Total amount with Samantha = $48
Single player games = $6 each
Multi player games = $12 each
Let
Number of Single player games = x
Number of Multi player games = y
The number of single player games (x) and the number of multi player games (y) Samantha can buy is
6x + 12y = 48
That is price × quantity of single player games + price × quantity of multi player games = Total amount with Samantha

At the beginning of the day the stock market goes down 50 1/2 points and stays at this level for most of the day. At the end of the day the stock market goes up 80 1/4 points from the low at the beginning of the day. What is the total change in the stock market from the beginning of the day to the end of the day?
Answer:
The change for the day is 29 3/4Step-by-step explanation:
In this problem, we are expected to calculate the change in the price of a particular stock
Given that the days high is 80 1/4
and also that the days low is 50 1/2
we can calculate the change by subtracting the days low from the days high
i.e 80 1/4- 50 1/2= 321/4-101/2= (321-202)/4= 119/4 = 29 3/4
hence the change for the day is 29 3/4
Also we can calculate the percentage change as
%change = (high-low)/low*100
%change= 80 1/4- 50 1/2/50 1/2= 29 3/4/50 1/2 *100
%change= 119/4*2/101 *100= 119/202*100= 0.589*100= 58.9%
%change= 58.9%

You're finding the distance around a two-dimensional shape.
can someone please help
Explanation:
The rule [tex](x,y) \to (-x,y)[/tex] has us flip the sign of the x coordinate from positive to negative (or vice versa). This applies a reflection over the y axis. For example, the point (5,6) moves to (-5,6).
Currently this shape is in quadrant 1. The quadrants start in the top right corner, and you move counterclockwise going to quadrants 2,3, and 4. Quadrant 2 is to the left of quadrant 1, and this is where all of the points end up after applying a reflection over the y axis.

Write an absolute value expression to represent the distance between -2 and 4 on an number line. Then evaluate the expression.
Answer:
|-2| + |4|
= 6
Step-by-step explanation:
The absolute value is the distance from zero on the number line, so you would use the expression above to get the answer, 6

Solve the equation using the Properties of Equality.
Answer:
m = 11/36
Step-by-step explanation:
6/7 m - 1/7 = 5/ 42
Multiply each side by 42 to clear the fractions
42(6/7 m - 1/7) = 5/ 42 *42
36m - 6 = 5
Add 6 to each side
36m -6+6 = 5+6
36m = 11
Divide each side by 36
36m/36 = 11/36
m= 11/36
