Answer:
64 I think
Step-by-step explanation:
You know that line DC is also equal to 8 so to find the area of triangle ABD you do 1/2*Base*Height which is 1/2*8*8 that is 32. The same thing goes for triangle CDB, so that is also 32. You add 32 and 32 which becomes 64.
Answer:
B
Step-by-step explanation:
There is a 1/4 probability of getting an A out of a bag with letter MATH
For B) There are two A's our of 8 letters is ADMIRALS.
2/8 is the same as 1/4
The answer is B
A) is wrong because that 1/6
C) is wrong because that's 1/8
D) is wrong because that's 2/9
Answer:
8 1/3
Step-by-step explanation:
Multiply 1 × 5 and 2/3 × 5
1 × 5 = 5
2/3 × 5 = 3
Then, add.
5 + 3 = 8
So, the answer is 8
Have a great day!
Answer:
<h2> 55.10min </h2>
Step-by-step explanation:
This problem is on the mensuration of flat shapes.
given that the initial radius before Cody alerted the fire department is
10 ft
Then we can calculate the area of the fire as
Area= πr^2
Area=3.142*(10)^2
Area=3.142*100
Area=314.2ft^2
Also, given that the area of the circular fire has grown to 45401 square feet
let us solve for the radius first, then we can calculate the time taken since the radius was increasing by 2 ft/min
let the radius of the large fire be R
45401=πR^2
R^2=45401/3.142
R^2=14449.714
square both sides we have
R=√14449.714
R=120.2ft
The difference between the radius of the initial fire and the large fire is
R-r=120.2-10
=110.2ft
Hence the time taken can be calculated as
time= 110.2/2
time=55.10min
