Step-by-step explanation:

find the area of the triangle

1/2BH

1/2*8*4

4*4=16

find the area half of the circle

pi*R^2

3.14*4^2

3.14*16

50.24/2

^because it is a half circle you divide by 2

25.12+16=41.1

It cost $36.75 for three tickets to visit the science center. It cost $51 for 4 tickets to visit the zoo. Which attraction will
Ber [7]
Find the cost for one ticket for the science center.
36.75 ÷ 3 = 12.25
Multiply the product with 12 to get the cost of 12 tickets.
12.25 × 12 = 147
Find the cost of 1 zoo ticket.
51 ÷ 4 = 12.75
Find the cost of 12 tickets by multiplying the product and 12
12.75 × 12 = $153
12 Science Center Tickets cost $147
12 zoo tickets cost $153

The Zoo costs more than the Science Center.

To find out how much more the Zoo costed, subtract 147 from 153.
153 - 147 = 6
The zoo only costs $6 more for 12 students.
So, you're answers are Zoo and $6

If There Where 240 heads and 210 tails.What Is the experimental probability that the coin lands on heads?​
Helga [31]
To find probability you have to add the samples that are included. In this situation, you add 240+210. Then you get 450. Then you divide heads by 450 to get the probability.




The probability is 240/450, which is 53%

In fractions it is 53 1/3.

The question is below thanks
iren [92.7K]

Answer:

10.02 units

Step-by-step explanation:

FH = \frac{82}{360} \times 2 \pi r (Multiplying the circumference of the circle by the arc's degree over the total degree of the circle will find the length of the arc FH)

FH = \frac{82}{360}\times 2 \pi (7)

=\frac{82}{360}\times14\pi

=\frac{287\pi}{90}

=10.02 (to the nearest hundredth)

∴ The length of the arc FH is 10.02 units to the nearest hundredth.

Hope this helps :)
