Find the surface area of the prism.

The surface area is_______
square meters.

Answers

total surface area is: 416 m^2

740 square meters

First you do 16 times 10 for the base(the square on the bottom), this equals 160.
Then you do 17 times 10 for sides. We have two of these so just add 170 plus 170 which equals 340.
Next use the formula A=bh/2 for the triangle. A=16(15)/2 this equals 240 but since we have two triangles then we don’t have to divide it.
Then add all of your numbers which are 240+160+340 and you get 740.

I hope this makes sense

Answer:

Step-by-step explanation

Since 1 2/3 is too large for the blank, and 0.153 is too small, we try C, which is 22%. Convert it to a fraction to make 11/50. If you cross multiply, we would find out that 11/50 is a greater fraction than 2/11 and less than 1.42. Hence, we get C as our answer.

Answer:

Step-by-step explanation:

2/11 = 0.18

22% is equivalent to 0.22, which is greater than 0.18, but less than 1.42

Stanley has two sets of three cards face down on a table. Each set contains: the 2 of hearts, the 5 of diamonds, and the 8 of clubs. He randomly turns over one card from each set.
Find the probability of each event:

a) Both cards are red.
b) The first card is red and the second card is black.
c) Both cards are even numbers.
d) The sum of the numbers is greater than 8.

Which strategy did you use each time?
Please explain your work.`

Answers

Answer:

a =4/9 = Both cards red

b =2/9 = 1st red 2nd black

c =8/12 = 2/3 simplified even numbers

d= 8/12 = 2/3 simplified sum adds to 8

Step-by-step explanation:

a) Both cards are red see b) 2/3 x 2/3 = 4/9

Answer 4/9

b) One of each colour red selected 1st then black

Answer = 2/3 x 1/3 = 2/9

Answer = 2/9

b) workings

(P2)Any colour RED

(P2)= S1: ( 2/3, 2/3, 1/3)

(P2) = S2: (2/3, 2/3, 1/3)

RED = 1 x 2/3 x 1/3 = 2/9 first card and second card BLACK= 1 x 1/3 = 1/3

Final = 2/9 x 1/3 = 2/9

Answer = 2/3 x 1/3 = 2/9

(P3) Even numbers

(P3)= S1: ( 2/3, 1/3, 2/3)

(P3) = S2: (2/3, 1/3, 2/3)

12 events 7 outcomes see chart below as two even numbers added will always be even numbers and so will two odds including 5+5 = 10

Answer = 8/12

(P4 ) Numbers that multiply to greater than 8

2 + 2 = 4

2 + 5 = 7

2 + 8 = 10

5 + 5 = 10

5 + 2 = 7

5+ 8 = 13

8 + 8 = 16

8 + 2 = 10

8 + 5 = 13

= 12 events either card and 8 opportunities

Answer = 8/12 simplified = 2/3

Write a numerical expression for 3 more than half of 16.

Answers

16 divideed by 2 =8 + 3

The value of numerical expression for 3 more than half of 16 is,

⇒ 3 + 1/2 (16)

⇒ 11

What is an expression?

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

The expression is,

⇒ 3 more than half of 16.

Now, We can write the numerical expression as;

Half of 16 = 1/2 (16)

And, 3 more than half of 16 is,

⇒ 3 + 1/2 (16)

⇒ 3 + 8

⇒ 11

Thus, The value of numerical expression for 3 more than half of 16 is,

⇒ 3 + 1/2 (16)

⇒ 11

Answer:

a(n+1) = a(n) + 9

Step-by-step explanation:

The terms just before and just after each are 9 more than the previous term or 9 less than the previous term. In other words, the common difference is 9.

Thus, the recursive formula is a(n+1) = a(n) + 9
