Let's say that 1/3 of the eggs become cracked. What is the ratio of the number of eggs that have cracked to the number of eggs t

vladimir2022 [97]

We can say we have 2 cracked egss and 4 uncracked eggs for a 6 egg total.

The ratio of cracked to uncracked eggs is 2:4 which reduces to 1 to 2.

Mr. Corbin measures the lengths of three branches. The first branch

anygoal [31]

Answer:

2nd branch > 1st branch > 3rd branch

$\dfrac{2}{2} > \dfrac{2}{3} > \dfrac{2}{8}$

Step-by-step explanation:

Length of First branch = $\frac{2}{3}$ foot

Length of second branch = $\frac{2}{2}$ foot

Length of third branch = $\frac{2}{8}$ foot

Let us convert the fractions in decimal forms:

$1.\ \dfrac{2}{3} = 0.67$

$2. \dfrac{2}{2} = 1$

$3.\ \dfrac{2}{8} = \dfrac{1}{4}=0.25$

It can be clearly seen that 1 is the largest value among the three values.

So, 2nd branch is the largest.

Now, let us have a look at the values of first and third branches:

0.67 and 0.25.

Clearly, 0.67 is greater than 0.25.

So, the correct order is:

2nd branch > 1st branch > 3rd branch

We can use other method to see it.

Here, all the 3 fractions have same numerator.

So, denominator can help us decide the which fraction has a large value.

If numerator is same, the larger denominator will have smaller fractions.

The denominators are 2, 3 and 8.

8 > 3 > 2

So, the answer is

2nd branch > 1st branch > 3rd branch

$\dfrac{2}{2} > \dfrac{2}{3} > \dfrac{2}{8}$

You survey two oak trees across a narrow but deep gorge. The results of your survey are shown below.

For this case what we must do is use the cosine theorem to solve the problem.
We have then:
$c ^ 2 = a ^ 2 + b ^ 2 - 2abcos (x)
$
Where,
a, b, c: are the sides of the triangle.
x: is the angle between the sides a and b of the triangle.
Substituting values we have:
$c ^ 2 = 90 ^ 2 + 75 ^ 2 - 2 (90) (75) cos (85)
$
Clearing c we have:
$c = \sqrt{90 ^ 2 + 75 ^ 2 - 2 (90) (75) cos (85)}$
Answer:
option 1
$c = \sqrt{90 ^ 2 + 75 ^ 2 - 2 (90) (75) cos (85)}$

What is parentheses 6 x to the 3 power y to the 5 power parentheses 2

choli [55]

(6x^3y^5)2

12x^3y^5

Explanation:
Because there is no addition or subtraction between 6x^3 and y^5, they are a part of ONE term so you don't multiply each of them separately.

Best of luck
