Answer: 91 in ²

This has to be answered in three parts:

1) Area of square
2) Area of triangle
3) Addition of both areas

Let’s start with step one: area of square. The easiest way to solve this sort of equation is by breaking the shape into two easier shapes and finding the area of both. I have attached an image below of how we will separate these shapes

Let’s find the area of the square.

Step 1) Write formula

l • w = a

Step 2) Fill in information and solve

7 • 11 = 77

That’s the area of the square! Now let’s move onto the triangle

Step 1) Write formula

1/2(b•h)

Step 2) Fill in information and solve

(Though it doesn’t say the base, we can find this by subtracting 15 and 11)

1/2(4•7)

1/2 (28)=14

That’s the area of the triangle side! Now let’s add these together for the final answer

Final Step: Finding final area

To find the area of the whole shape, let’s add these two together

Triangle: 14
Square:77

14+77=91

Hope this is right and it helps comment below for more questions :)

Answer:

91 in²

Step-by-step explanation:

Area of tarpezoid = (sum of both bases x height) / 2

A = ((11 + 15) x 7) /2 = 91

Answer:

D. X< 4

Step-by-step explanation:

12(x-2) < 24

divide both sides by 12

so we get

(x-2) < 2

now add 2 to both sides

x < 4

BabaBlast [244]

Answer:

Boris will have $250 in 10 months.

Step-by-step explanation:

$25 = one month.

$250= ?months

To find ?, the months we divide 250 by 25 to get this:

250 ÷ 25 = 10

10 months is the amount of time Boris will have to wait until he saves up $250.

Hope this helps you! Good luck with your quiz! :)

Find the probability of at least three successes in six trials of a binomial experiment in which the probability of success is 5
Amanda [17]

Answer:

31.3%

Step-by-step explanation:

Start by doing the binomial expansion of (x+y)^6 where x represents success. This is  

(x^6y^0) + 6(x^5y^1) +15(x^4y^2) +20(x^3y^3) +15(x^2y^4) +6(x^1y^5) +(x^0y^6)  

We are interested in the x^3y^3 term which represents exactly 3 successes. Since the probability of success and failure are both .5 we should be able to figure this out just using the coefficients of the terms which is  

20/64 = .3125 which is 31.25% Rounding yo the nearest tenth gives us

Stolb23 [73]

Answer:

Multiply the numerator by the reciprocal of the denominator. Multiply x x by 1 1 . Since g(f(x))=x g ( f ( x ) ) = x , f−1(x)=1x f - 1 ( x ) = 1 x is the inverse of f(x)=1x f ( x ) = 1 x .
