Answer:
- B. 160 unit²
Step-by-step explanation:
Given isosceles trapezoid
<u>First find the base of the triangle with side of 10 and dotted segment (h):</u>
- b = 1/2(26 - 14) = 6 units
<u>Find the height of the trapezoid, use Pythagorean:</u>
- h =
=
= 8 units
<u>Find the area of the trapezoid:</u>
- A = 1/2(26 + 14)(8) = 160 unit²
Correct choice is B

One way is to factor and group and get every 3
729=3 times 3 times 3 times 3 times 3 times 3
so we group the ones that happen 3 times
729=(3*3*3) times (3*3*3)
we know that we can take the cube root of each group and multiply the result
729=![( \sqrt[3]{3*3*3})( \sqrt[3]{3*3*3})](https://tex.z-dn.net/?f=%28%20%5Csqrt%5B3%5D%7B3%2A3%2A3%7D%29%28%20%5Csqrt%5B3%5D%7B3%2A3%2A3%7D%29)
=(3)(3)=9
the answer is 9
729=3 times 3 times 3 times 3 times 3 times 3
so we group the ones that happen 3 times
729=(3*3*3) times (3*3*3)
we know that we can take the cube root of each group and multiply the result
729=
the answer is 9
Check the picture attached.
Let OB be the radius of circle with center O.
Let B' be the image of B after the described rotation
OB and OB' are sides of the equilateral triangle OBB'.
The x coordinate of B' is the midpoint of OB, that is 5.
In the right triangle B', point (5, 0) and B:
Distance point (5, 0) to B is 5
|B'B|=|OB|=10
so by the pythagorean theorem:

Answer: a)
b) 25165824000
Step-by-step explanation:
The exponential equation for growth is given by :-
, where a= initial value , b =multiplicative growth factor and t = time.
Given : A bacteria culture contains 1500 bacteria initially and doubles every hour.
i.e. a = 1500 and b= 2
Then, the function N that models the number of bacteria after t hours will be :
To find , the number of bacteria after 24 hours , we put t= 24 in above equation , we get
Hence, the number of bacteria after 24 hours is 25165824000.

Answer is in attached image.
Step-by-step explanation:
Given the expressions, for which we have to find the estimates as per the expressions on the left.
The given expressions are:
1) 35 23
2) 132 168
3) 17.3 18.4
4) 999 208
5) 998 211
Here, we need to find the rounded off numbers.
35 can be rounded to 40 and 23 to 20.
Therefore, equivalent to 35 23 is 40
20
132 can be rounded to 130 and 168 to 170.
Therefore, equivalent to 132 168 is 130
170.
17.3 can be rounded to 17.0 and 18.4 to 18.0.
Therefore, equivalent to 17.3 18.4 is 17.0
18.0.
999 can be rounded to 1000 and 208 to 210.
Therefore, equivalent to 999 208 is 1000
210.
998 can be rounded to 1000 and 211 to 210.
Therefore, equivalent to 998 211 is 1000
210.
The solution can be found in the attached image as well.
