P=pages and H=hours, I’m assuming she read 20 pages, so C. h=20p should be correct, sorry if it wrong tho :)
Answer:
172.12 sq in
Step-by-step explanation:
The figure is comprised of a semicircle, and 2 rectangles
Area of semicircle = 1/2(3.14)4^2 = 25.12
Area of rectangle with length of 9 and width of 7 = 7(9) = 63
Area of rectangle with length of 14 and width of 6 = 6(14) = 84
Total area = 25.12 + 63 + 84 = 172.12 sq in
Answer:
Each cookbook cost $15.15.
Step-by-step explanation:
Since the statement indicates that four cookbooks and one novel cost $68.75, you can write the following equation:
4x+y=68.75, where:
x is the price of cookbooks
y is the price of novels
Also, given that the novel cost 7 dollars less than a cookbook, you can write the following equation:
x=y+7
Now, you can replace x=y+7 in the first equation:
4(y+7)+y=68.75
4y+28+y=68.75
5y=40.75
y=40.75/5
y=8.15
Now, you can replace the value of y in x=y+7:
x=8.15+7
x=15.15
According to this, the answer is that each cookbook cost $15.15.
(0,7) , (7,8)
Y-intercept is at (0,7) and the slope is 1/7 so from the y intercept, go up 1 and over 7.
3x^2 - 2x^2y + 2xy^2 + 4y^2 + xy^2 - y^2 + 2x^2y
= 3x^2 + 3y^2 + 3xy^2
answer
3x^2
3y^2
3xy^2
