Answer:
<em>The distance between each picture is 37 inches</em>
Step-by-step explanation:
We must find the separation between each picture knowing the total space they will occupy and their individual dimensions. We are not told if the distance between them is the same as that from the borders, we'll assume it is.
The total width of the wall is 17 ft=17*12=204 inches
Two pictures are horizontal and occupy 20 inches each, for a total of 40 inches
One picture is vertical and occupy 16 inches. This means the total space occupied by the pictures is 40+16=56 inches.
The difference between the total width of the wall and this distance will be equally spaced. This difference is 204 - 56 = 148 inches
There are 4 spaces to be equally sized: two between the pictures and two to the borders. The separation of each must be 148/4=37 inches
The distance between each picture is 37 inches
Answer:
2 : 9
Step-by-step explanation:
Put the given numbers in the expression and simplify:
bikes before : total bikes
= (bikes before) : (bikes before) + (bikes bought)
= 6 : (6 +21)
= 6 : 27
= 2 : 9

A question like this would do little to convince you ratios have some usefulness. There appears to be no point whatever to knowing the fraction of older bikes.

Ratios are used many places in the real world. Perhaps the ratios you encounter most frequently are tax rates.
If you spend any time cooking, you know that certain ratios of ingredients produce better taste and/or texture than other ratios, and you know that (generally) changing the quantity a recipe produces will involve changing all the ingredient amounts by the same ratio.
Finance, health, time, diet budgets are often specifies as ratios: 14% APR, 2.3 infant deaths per 1000 live births, 2 hours outside class for each hour in class, 25% of calories from fat, and so on.
Of course, chemistry is all about ratios. CO₂ and H₂O are perhaps some of the more important ratios in the world right now. These specific ratios of carbon, hydrogen, and oxygen atoms make substances that are both life-giving and life-threatening. Much study is directed at determining and maintaining appropriate ratios of these substances relative to others.
Bro i don’t have calculator on me rit now but i will tell you how to do it pretty much you have to get 21 cookies or somethhing times that by 21
The coordinates of the reflected point that is reflected across the x-axis to obtain a new point is (1,5).
