Answer:

6. 1800

7. 49

Step-by-step explanation:

estimation is to round to easy numbers first and then multiply or divide, which can then be done easily in our heads.

so, for 6. I rounded to 60 pages per day and 30 total days (the nearest tens). one factor of the multiplication I rounded a little bit down, the other one a little bit up. therefore the total result should still be near that.

for 7 I did a similar thing. I rounded 975 to 980 and 23 to 20. just now we need to divide.

980 / 20 = 98/2 = 49

Find the area of the region bounded by the y-axis, the line y=6, and the line y = 1/2.
Ghella [55]

Solution:

As region bounded by y-axis, the line y=6, and the line y=1/2 is a line segment of definite length on y-axis.

We consider a line , one dimensional  if it's thickness is negligible.

So, Line is  two dimensional if it's thickness is not negligible becomes a quadrilateral.

So, Area (region bounded by y-axis, the line y=6, and the line y=1/2 is a line segment of definite length on y-axis)= Area of line segment between [,y=6 and  y=1/2.]= 6-1/2=11/2 units if we consider thickness of line as negligible.

Daniel runs 40/5 miles in 124/₁ minutes. What is the unit rate in terms of miles per minute? What the answer:
sasho [114]

Using the given information, the unit rate is 0.0645 miles/minute

<h3>Calculating rate </h3>

From the question, we are to determine the unit rate

From the given information,

Daniel runs 40/5 miles in 124 minutes

That is,

Distance = 40/5 miles = 8 miles  

Time = 124 minutes

Using the formula,

Rate = Distance / Time

Rate = 8 miles / 124 minutes

Rate = 0.0645 miles/minute

Hence, the unit rate is 0.0645 miles/minute
