Answer:

Step-by-step explanation:

Since all sides are half of greater triangle.Then 7 × 2 = 14 is length of greater hypotenuse.

Suppose two triangles with similar conditions

1^2+1^2=2

Hypotenuse=2^1/2

We assume another triangle which is exactly double of previous triangle I.e

2^2+2^2=8

Hypotenuse=2×2^1/2

Which is exactly twice of previous triangle.

Hence proved hyootenuse is double of smaller triangle I.e 14

Answer:

Here we will show you how to calculate 1/6 divided by 7/8. We will give you the answer in fraction form and in decimal form.

Here is 1/6 divided by 7/8 displayed mathematically in colors:

The numbers in 1/6 divided by 7/8 are labeled below:

1 = dividend numerator

6 = dividend denominator

7 = divisor numerator

8 = divisor denominator

To make it a fraction form answer, you multiply the dividend numerator by the divisor denominator to make a new numerator.

Furthermore, you multiply the dividend denominator by the divisor numerator to make a new denominator:

1 x 8

6 x 7

Thus, the answer to 1/6 divided by 7/8 in fraction form is:

Anna [14]

Answer:

c = 58x

Step-by-step explanation:

A linear equation is an equation in the form of f(x) = mx + c. Where m is the slope and c is the intercept.

Let the price of one guitar lessons be x, then 47guitars will be 47x and 11 guitar lessons will be 11x. All together will be 47x + 11x = 58x.

Thus, the total cost, c, is

c = 58x

Allushta [10]

Answer:

The answer is "0.07404893".

Step-by-step explanation:

Applying the binomial distribution:

$n = 22\\\\p= 82\%=0.82\\\\q = 1-0.82 = 0.18\\\\$

Calculating the probability for not enough seats:

$=P(X>20)\\\\= P(21) + P(22)\\\\$

$= \binom{22}{21} (0.82)^{21}(0.18)^1+ \binom{22}{22} (0.82)^{22}(0.18)$

$=0 .06134598+ 0.01270295\\\\=0.07404893$

DOES ANYONE USE THIS APP? <br>I NEED HELP

Answer:

You can determine the root of the equation by multiple methods. However, that answer is correct. The root is -2.

Step-by-step explanation:

A root is where the graph crosses the x-axis. One trick I use to see if it is a root is by taking the numerator and plugging in the number for x. For example, $\frac{x+2}{x^{2} -2}$ , and take the -2 and plug it in for x. The numerator would cancel out because -2 + 2 = 0. That is the way you can determine if it is a root or not.
