Rob is saving to buy a new MP3 player. For every $15 he earns babysitting, he saves six dollars. On Saturday, Rob earned $75 babysitting. How much money did you save?

Answers

Answer 1

Answer: If he saves $6 from every $15 he gets, then getting $75 means he saves $30.
Lets says he is paid 15 dollars every hour, and from those he saved 6 dollars. If he earned 72 dollars, that means he is paid 5 times (because 75/15 is 5). So if every time he is paid he saves $6, being paid 5 times means he saves $30 ($6 *5).

Find The area of The rectangle below \ 7 FT 6/10 FT

Answers

Lets first simplify the dimensions of the rectangle
length = 7
breadth = $(6)/(10)$ = $(3)/(5)$ = 0.6
The area of rectangle = length * breadth
so, area of rectangle = 7 * 0.6

Area of rectangle = 4.2

Can someone help me with this math question?

Answers

Answer:

y = x + 2

Step-by-step explanation:

the formula for this basic equation is

y = mx + b

m = 5/5 (slope)

b = 2 (y-intercept)

5/5 simplified is just 1

so if we put it in the equation you get y = 1x + 2

but 1x is the same as just saying x

y = x + 2

How can you use models to explain why 3.1=3.10?

Answers

Answer:

3.1 = 3.10 because adding zero (0) in decimal number at the right most side doesn't affect the number as the same way adding zero at the left most side of a number doesn't affect the number.

Also, 3 and 1 ones are the same as 3 and 10 tenths.

Adding a zero would not do anything after a decimal because 1 is the tenth, and adding a zero will still make it 3 wholes and 1 tenth....0 hundredths.

That is why 3.1 = 3.10

What is the equation of the graphed linear model? y = x + Scatter plot on a first quadrant coordinate grid. The horizontal axis is labeled Variable A. The vertical axis is labeled Variable B. Points are plotted at (one, three), (two, ten), (three, six), (four, eight), (five, four), (six, nine), (seven, seven), (eight, eight), (nine, eleven). A line is drawn through point (one, three) and point (nine, eleven).

Answers

If you have line on the scatter plot that is drawn through the points (1,3) and (9,11) then we will first calculate the slope:
m=(y2-y1)/(x2-x1)=(11-3)/(9-1) = 8/8 = 1
Then the interception with y-axis:
y=mx+b
3= 1*1 + b
3-1=b
b=2
The equation is:
y=x+2

Answer:

m=(y2-y1)/(x2-x1)=(11-3)/(9-1) = 8/8 = 1

Then the interception with y-axis:

y=mx + b

3= 1*1 + b

3-1=b

b=2

The equation is:

y=x+2
