Answer:

1/8 because {(T , T , T), (T , T , H),(T , H , T), (T , H , H),(H , H , H),(H , H , T),(H , T , H),(H , T , T)} which has 8 combinations in total so that means 1/8... 8 is denominator because 8 combinations 1 is for each one.

Answer:

$m\angle y=35.69^o$

Step-by-step explanation:

The picture of the question in the attached figure

we know that

In the right triangle of the figure

$sin(y)=\frac{7}{12}$ ----> by SOH (opposite side divided by the hypotenuse)

using a calculator

$m\angle y=sin^{-1}(\frac{7}{12})=35.69^o$

Tom brought 7/8 gallons of water to a party and his friends drank2/3 of it. How many gallons of water did they drink?

natka813 [3]

In plain and short, what's 2/3 of 7/8? well, is just their product.

$\bf \cfrac{7}{8}\cdot \cfrac{2}{3}\implies \cfrac{7\cdot 2}{8\cdot 3}\implies \cfrac{14}{24}\implies \stackrel{simplified}{\cfrac{7}{12}}$

Write and solve an equation to find the unknown side length x (in inches). Perimeter =24.2 in. Sides of the shape are 8.3, 8.3,

Anastasy [175]

Answer:

Perimeter of shape,which is a convex polygon i.e quadrilateral = 24.2 in

Sides are 8.3 in, 8.3 in, 3.8 in ,and length of fourth side be x in.

As , Perimeter = Sum of all sides

→ 24.2 = 8.3 + 8.3 + 3.8 + x

→ 24.2 = 16.6 +3.8 + x

→ 24.2 = 20 .4 + x

Keeping like terms on one side, of equation

→ 24.2 - 20.4 = x

→ 3.8 = x

→ x = 3.8

So, length of fourth side = 3.8 in

The given shape is definately either a Parallelogram or a kite.

How could you find an even better estimate of the square root of 2

vodomira [7]

Answer:

First of all you need to know the $\sqrt {4}$ it's equal to 2 and

$\sqrt {1}$ which is the number is between 1 and 2 and between that number there maybe the possibilities of above 0.5 or under 0.5

After that Figure out which one was bigger? $\sqrt {2}$ or $\sqrt {3}$ ? The answer is $\sqrt {3}$ and $\sqrt {3}$ also near to $\sqrt {4}$ so it should be above 0.5 .

So we know that $\sqrt {2}$ is between 1 and 1.5.

Hopes that information was help you a lot
