Answer:

In the equation of a straight line (when the equation is written as "y = mx + b"), the slope is the number "m" that is multiplied on the x, and "b" is the y-intercept (that is, the point where the line crosses the vertical y-axis). This useful form of the line equation is sensibly named the "slope-intercept form"

The volume formula is area of base×height. In this case, we are working with rectangles, so the formula is l×w×h. We have to find the volume of each block and add them together. Top rectangle: 12×30×4=1440. Middle rectangle: 30×36×4=4320. Bottom rectangle: 30×60×4=7200. 7200+4320+1440=12960 inches squared.

8 1/5 + 4 2/5 i need to know cus i dont understand it
inessss [21]

Answer:

63/5 or 12 (3/5)

Step-by-step explanation:

It is 8 whole (1 ÷ 5) plus 4 whole (2 ÷ 5)

So,we can write it as 8 (1/5) + 4 (2/5)

Then we will take those mixed fractions to improper fractions by using the rule of multiplication.

8 will be multiplied by 5 and then the value will be added to 1. Same rule will be applied for the second fraction.

(41÷5) + (22÷5)

Now we will take L.C.M. (Least common multiple) for both denominators 5 and 5. The L.C.M of 5 and 5 = 5

(41 + 22)/5

= 63/5

It is the answer. Also we can make this improper fraction into mixed fraction by dividing the whole number by 5.

12 (3/5)

I need some help on number 15 please...
kondaur [170]
To solve this problem, all you need to do is make a standard graphing equation. The first step is finding mode using two points from the table. We'll use (1, 70) and (2, 90).
\frac{y_{1}- y_{2}  }{ x_{1}- x_{2}}  \\  \frac{70-90}{1-2}  \\  \frac{-20}{-1}  \\ 20
From the work, we've found that the slope of this equation is 20.

Next, we need to finish writing the equation and plug in the coordinates to solve for the y-intercept.
y=20x+b \\ 90=20(2)+b \\ 90=40+b  \\ (90)-40=(40+b)-40 \\ b=90-40  \\ b=50

Now we have all the information we need to write our equation, which is:
y = 20x+50

Hope this helps!
