Hi there!
Let's solve this problem step by step!
A bottle contains 70% alcohol. First we need to convert this percentage into a decimal. To do this, we only need to divide by 100.
70 % = 70 / 100 = 0.7
The entire bottle contains 500 ml of solution. To find the amount of alcohol in the solution, we must multiply our (just found) decimal by the total content of the bottle.
0.7 * 500 ml = 350 ml
Therefore there are 350 millimetres of alcohol in the solution.

If the ratio of x/y or x/y is always the same constant, then a and y are directly proportional and the constant is called the constant of proportionality.
<span>If the product of xy is always the same constant, then a and y are inversely proportional and the constant is called the constant of proportionality. </span>
<span>unit rates --- are like any rate found by dividing --- like speed --- miles per hour unit means 1 and this is miles traveled in one hour (at constant speed) --- so you just divide --- traveling 100 miles in 2 hours = 50 miles in 1 hour --- 50 miles per hour --- miles/hour <<< that is a unit rate </span>
<span>slope is a rate of change --- on an x-y coordinate axis graph the slope is the rate of change of y compared to a change in x --- this is not necessarily a unit rate ... slope of 2/3 means a change of 2 for y will create a change of 3 for x (not a change of 1, so it is not a unit rate)</span>
Answer:
4171/5000
Step-by-step explanation:
When diving 4171 by 5000, you get the answer of 0.8342. If you are using a calculator, you can use a button that allows you to convert decimals to fractions and vice versa.
Answer:
(d) -11
Step-by-step explanation:
The sum of the acute angles of a right triangle is 90°. (That makes the sum of all angles be 180°, as it is for any triangle.)
65° +(36 +x)° = 90°
x = 90 -101 . . . . . . . . divide by °, subtract 101
x = -11
To proof
Given: Length =12cm, width= 18cm, height = 22cm
volume of the rectangular prism (say V1) = length × breadth × height
= 12×18×22cm³
=4752 cm³
when dimensions are doubled
New length = 24 cm, New breadth =36 cm, New height =44 cm
volume of the rectangular prism (V2)= 24×36×44 cm³
= 38016 cm³
= 8(4752)cm³
This shows when the dimension doubled the volume of rectangular prism be 8 times the volume of the first one.
Therefore,
