Step-by-step explanation:

a of triangle=1/2 ×b×perpendicular height

a= 1/2×2×3

a=3 in

3×4=12 in ( times by 4 because their is 2 is isosceles triangles which are both half make 4 right angled triangles)

10×4=40

40×3=120(times by 3 because there is 3 rectangles

120 in + 12 in=132 $in{2}$

What is the value of the expression shown below 10+(2x3)^2 divided by 4x (1/2)^3

stira [4]

Answer:

10 + (2 x 3)^2 / 4 x (1/2) ^3

First do the parentheses

2 x 3 = 6

1 / 2 = 0.5

We are left with

10 + 6^2 /4 x 0.5^3

Do exponents

6 x 6 = 36

0.5 x 0.5 x 0.5 = 0.125

10 + 36 / 4 x 0.125

Divide by 4 and multiply by 0.125

36 / 4 = 9

9 x 0.125 = 1.125

We are left with

10 + 1.125 = 11.125

The answer is 11.125

The probability for rolling a sum of 7 is: 1/6

Step-by-step explanation:

Given that two six-sided dies are rolled the total outcomes will be:

$6*6 =36$

n(S) = 36

Out of total outcomes we have to count the outcomes that sum up to 7

Let A be the event that the sum of outcomes is 7

$A = \{(1,6), (2,5), (3,4) , (4,3) , (5,2), (6,1)\}$

Here the first number is the result of first die and second number is the result of 2nd die.

n(A) = 6

So the probability of A will be:

$P(A) = \frac{n(A)}{n(S)}\\\\=\frac{6}{36}\\\\=\frac{1}{6}$

Hence,

The probability for rolling a sum of 7 is: 1/6
