Is that a ratio? then i’ll answer it
Answer:
The possible digits 0, 1, 2 , 3 or 4 .
Step-by-step explanation:
The possible digits that could go in the thousands place to make 13_,644 ≈ 130,000 this statement correct are: 0 1, 2,3 or 4.
<u>For example:</u> 132,644 may rounded off to 130,000
Round the number to the nearest thousand make the numbers whose last three digit through 644 into the next lower numbers that ends in 000.
Using number line for this possibility as shown in the below diagram:
Answer:
<u>2 : 5</u> is the ratio of the amount of juice to the amount of ginger ale.
Step-by-step explanation:
Given:
You mix 1 and one half quarts of juice with 3 and three fourths quarts of ginger ale to make fruit punch.
Now, to get the ratio of the amount of juice to the amount of ginger ale.
Amount of juice = ![1\frac{1}{2}=\frac{3}{2} \ quarts.](https://tex.z-dn.net/?f=1%5Cfrac%7B1%7D%7B2%7D%3D%5Cfrac%7B3%7D%7B2%7D%20%5C%20quarts.)
Amount of ginger ale = ![3\frac{3}{4}=\frac{15}{4} \ quarts.](https://tex.z-dn.net/?f=3%5Cfrac%7B3%7D%7B4%7D%3D%5Cfrac%7B15%7D%7B4%7D%20%5C%20quarts.)
So, to get the ratio of amount of juice to amount of ginger ale:
![\frac{3}{2} :\frac{15}{4}](https://tex.z-dn.net/?f=%5Cfrac%7B3%7D%7B2%7D%20%3A%5Cfrac%7B15%7D%7B4%7D)
![=\frac{\frac{3}{2}}{\frac{3}{4}}](https://tex.z-dn.net/?f=%3D%5Cfrac%7B%5Cfrac%7B3%7D%7B2%7D%7D%7B%5Cfrac%7B3%7D%7B4%7D%7D)
![=\frac{3}{2} \times \frac{4}{15}](https://tex.z-dn.net/?f=%3D%5Cfrac%7B3%7D%7B2%7D%20%5Ctimes%20%5Cfrac%7B4%7D%7B15%7D)
![=\frac{12}{30}](https://tex.z-dn.net/?f=%3D%5Cfrac%7B12%7D%7B30%7D)
On simplifying it:
![=\frac{2}{5}](https://tex.z-dn.net/?f=%3D%5Cfrac%7B2%7D%7B5%7D)
![=2:5.](https://tex.z-dn.net/?f=%3D2%3A5.)
Therefore, 2 : 5 is the ratio of the amount of juice to the amount of ginger ale.

Answer:</h3>
7![\sqrt{2}](https://tex.z-dn.net/?f=%5Csqrt%7B2%7D)

Step-by-step explanation:</h3>
The triangle shown is a 45-45-90 triangle. This name comes from the fact the 3 angle measurements are 45, 45, and 90 degrees.
If needed, you could find the missing angle using the equation: 180 - (45 + 90) = x.
Special Right Triangles
Special right triangles allow us to use formulas and shortcuts to find missing sides easily. Another type of special right triangle is the 30-60-90 triangle. While both of these are special right triangles, they have different formulas.
Formulas
All 45-45-90 triangles have 2 types of sides: the legs (a and b) and the hypotenuse (c).
- c = b
![\sqrt{2}](https://tex.z-dn.net/?f=%5Csqrt%7B2%7D)
- b = a
- a = b
In these triangles, both of the legs are congruent.
Solving for c
Since we are given b, we can just plug the b-value into the formula that solves for c.
- c = 7
![\sqrt{2}](https://tex.z-dn.net/?f=%5Csqrt%7B2%7D)
The answer cannot be simplified further, so this is the final answer.
