Step-by-step explanation:
Ratios are also used to express relationships between part to a
whole In this problem, we are expected to sight more examples of ratios.
other examples of ratios are
1. the ratio of boys to girls in a class
for every 1 boy, there are 3 girls
1:3
2. the ratio of cats to dogs in a house
say for every 2 cats there are 5 dogs
2:5
We can go on and on, as the list of examples can be endless, the basic idea is we can relate part to part as in these examples given or a part to a whole using ratios.
Answer:
To solve this problem, all we have to do is to use a conversion factor to convert millisecond into seconds. We know that there are 1000 milliseconds in a second, therefore:
pitcher’s arm rotation = 7 degrees / millisecond * (1000 milliseconds / second)
pitcher’s arm rotation = 7,000 degrees / second
Step-by-step explanation:
Answer:
Oil: 24 ml; Onion: 56 g; Potatoes: 0.36 kg; Milk: 0.44 l
Step-by-step explanation:
First, we see how much of the soup recipe he wants make.
4 portions out of 20 portions = 4/20 = 1/5 = 0.2
He wants to make 0.2 of the amount of the recipe.
Now we multiply every amount by 0.2
Oil: 0.2 * 120 ml = 24 ml
Onion: 0.2 * 280 g = 56 g
Potatoes: 0.2 * 1.8 kg = 0.36 kg
Milk: 0.2 * 2.2 l = 0.44 l
When a point P(a, b) is reflected about the y-axis, the coordinates of the reflected point are P'(-a, b).
Thus, the reflection of point (3, 7) is (-3, 7), as shown in the picture.
Answer: (-3, 7)
4 - 5x = 2x + 25
4 = 7x + 25
-21 = 7x
-3 = x
4 - 5x + 2x + 25 = ac
4 - 5(-3) + 2(-3) + 25 = ac
4 - (-15) + (-6) + 25 = ac
19 + (-6) + 25 = ac
38 = ac
