Answer:
57.72 in^2
Step-by-step explanation:
Question 1. Shapes are triangle, semi-circle, and rectangle.
Question 2.Find area of rectangle first. Then area of triangle and circle. Subtract area of triangle and circle. Then add the difference with the rectangles area.
Question 3.
Rectangle's area:<u>48 in^2</u>
Triangles area:8*4/2= <u>16 in^2</u>
Circle Area: pi*r^2/2(since its a semi-circle)
3.14*2^2=3.14*4=12.56/2=<u>6.28 in^2</u>
Question 4.
16-6.28=9.72
9.72+48=57.72 in^2

Step-by-step explanation:,,
Answer: It will be explained below. Basically, 463.846154 minutes in total to read the rest of the book, and she reads at 78 pages per 90 minutes, or 13 pages per 15 minutes.
Step-by-step explanation: Shryia read 78 pages in 90 minutes - she had read 480-402, which is 78. This indicates a fairly annoying-to-calculate rate of 78 pages every 90 minutes, which is annoying to calculate, but please bear with it. The quantity of remaining pages is 402, of course, and as such we can simply divide this by 78 pages/90 minutes.
1. 402 pages divided by 78 pages/90 minutes
2. 402 pages multiplied by 90 minutes/78 pages (flipped the fraction; 90 minutes is now the numerator.)
3. 402 multiplied by 90 minutes/78 (reduced and removed the "pages" from each.)
4. 36180 minutes/78 (multiplied 402 to 90.)
5. 463.846154 minutes (divided 36180 by 78).
I hope this provides some insights.
Rule of exponents:
when bases are the same - They are both x's - you add the exponents.
x^(-8 + -2) = x^(-10) or 1/x^10)
Answer:
D) 0.0796
Step-by-step explanation:
Birth weights in Norway are normally distributed with a mean of 3570 g and a standard deviation of 500 g.
mean = 3570 and SD = 500
We need to find P(3500<x<3600)
P(3500<x<3600)= P(x=3600)- P(x=3500)
to find P(x=3600) we find z-score
Now use z-score table . z-score = 0.5239
P(x=3600)=0.6179
to find P(x=3500) we find z-score
Now use z-score table . z-score = 0.4443
P(x=3600)=0.4443
P(3500<x<3600)= P(x=3600)- P(x=3500)
P(3500<x<3600)=0.5239-0.4443 = 0.0796
