Answer 1
Answer: You have 2 triangles and 3 rectangles. 
Start with a triangle:
area is base side * height / 2 ->  4 * 3 / 2 = 6
The other triangle has the same area: 6

First rectangle: side * other side -> 7 * 5 = 35
Second rectangle: 7 * 4 = 28
Third rectangle: 7 * 3 = 21

Now simply add all this together: 6+6+35+28+21 = 96

Plot the numbers -2 and 5/6 and 7/3 on the number line

Answers

For the first one go -2 back, then go 5/6th of the way to -3. For the next one, convert to a mixed fraction by dividing the numerator as many times as possible by the denominator, putting the result as the whole number off to the left, then put the remainder as the numerator and keep the same denominator.

Bobby made cookies. the circumference of cookies are 6 cm. what is the diameter of the cookies?

Answers

To find the circumference you would multiply the diameter by pi(3.14) so you do the opposite. Divide 6 by 3.14 (pi) and you should get your answer: 19.1 or something similar.

Rita is spending more time at home to study and practice math. Her efforts are finally paying off. On her first assessment she scored 58 points, then she scores 63 and 68 on her next two assessments. If her scores continued to increase at the same rate, on which assessments will she be scoring above 85?

Answers

Answer

She will be scoring above 85 after her 7 assessment.

Explanation

We can model this situation using a line equation.

We know that on her first assessment, Rita scored 58 points, so our first point is (1, 58)

We also know that on her second assessment, Rita scored 63 points, so our second point is (2, 63)

To find the rate, which is the slope of our line, we are using the slope formula:

m=(y_(2)-y_(1))/(x_(2)-x_(1))

where

(x_(1),y_(1)) are the coordinates of the first point

(x_(2),y_(2)) are the coordinates of the second point

From our points we can infer that x_(1)=1, y_(1)=58, x_(2)=2, y_(2)=63. Let's replace the values in our slope formula:

m=(y_(2)-y_(1))/(x_(2)-x_(1))

m=(63-58)/(2-1)

m=(5)/(1)

m=5

Now we know that Rita's score is increasing 5 points every assessment.

To complete the equation of our line, we are using the point slope formula:

y-y_(1)=m(x-x_(1))

y-58=5(x-1)

y-58=5x-5

y=5x+53

Finally, we just need to replace y with 85 in our line equation and solve for x to find after which assessment she will score above 85:

85=5x+53

32=5x

x=(32)/(5)

x=6.4

Since we can't have 0.4 assessment, she will be scoring above 85 after her 7 assessment.  


This is a pattern in which you add five points to the next assessment. 
1st= 58, 2nd=63, 3rd=68, 4th=73, 5th= 78, 6th=83, 7th=88 points
So on her seventh assessment, she will get higher than 85 points. 
Hope this helps.
