Answer 1

Answer:

If I am thinking correctly its 72.

Step-by-step explanation:

I multiplied 9 x 8 and I got 72, and if I remember correctly your supposed to multiply to get the area.

Hope this helps :>

Answer 2
Answer : 124ft to the nearest whole number.

Explanation: the formula to find the lateral surface area of a cone is pi times the radius times the slant height. The slant height can be found by rooting the radius squared plus the height squared.

So, 4^2 plus 9^2 rooted multiplied by pi and by the radius, which gives you an answer of 123.7644 which is 124 to the nearest whole number.

Hope this helps.

Answer:

 

The answer is B. 39.0

Step-by-step explanation:

To find the average we add all the numbers then divide it by the total amount of numbers

= 23 + 33 + 33 + 27 +25 + 68 + 27 + 44 + 72/9

= 352/9

= 39.111111111

Round it of to the nearest tenth

= 39.0

Can someone please help with this! All the information i have is in the screenshot-

Part A:

So basically you use this formula to find the best-guessed height and length of the rectangular prism.

1029/7√=

147√=

12.12436

So the best-guessed height and length were both 12.12436.

Now take this info you learned from calculating the best-guessed height and length of the left prism. We are now going to use 12.12436 as the height and length for the right prism. Now make sure to use the order of operations rule "PEMDAS" to solve this equation. If you don't you will get the wrong answer.

12.12436(8)²=

147(8)=

1176

So the best-guessed volume of the right prism is 1176.

Part B:

So basically what you have to do is divide 1029 by the solution of    height×width which will give you your length.

1029/(14×7)=

1029/98=

10.5

So the best-guessed length of the left prism is 10.5.

Now you will use this info to solve your problem

14×8×10.5= 1,008

1008/8√=

126√=

11.22497

So the best-guessed height would be 11.22497.

Answer:

x=+10

Step-by-step explanation:

I hope that helps I think it's the right answer if my calculations are correct it's +10

Answer : x = 10

In a triangle, the angles add up to 180 degrees. 46 + (8x-2) must be equal to 11x + 14, as angles on a straight line also equal to 180 and therefore 180 - (11x + 14) is the missing interior angle on the triangle. (angle ABC + angle BAC = angle BCD)
Using these substitutions, we can calculate x.

(8x - 2) + 46 = (11x + 14)
(80 - 2) + 46 = (110+14)
