Answer: 25%
Step-by-step explanation:
1/4 of 100 is 25.
100/4 is 25
15.
2500 X 15 = 37500
37500 ÷ 100 = 375
375 + 200 = 575
The answer is C.
16.
The easiest way to answer this question is by going through each answer one by one:
14:6 = 28:18
28 <span>÷ 14 = 2
</span>18 <span>÷ 6 = 3
</span>Since both numbers were multiplied by different numbers, we can establish that this is not a true proportion.
42:7 = 6:2
42 ÷ 7 = 6
7 ÷ 7 = 1
42:7 = 6:1
By dividing both numbers by the same number, we can establish that the answer is wrong.
2:3 = 3:2
This is obviously wrong. That is because, in ratios, the order counts. So the first 3 is more than the first 2, therefore the second number on the other side of the ratio should be more than the first.
3:5 = 12:20
12 <span>÷ 3 = 4
</span>20 <span>÷ 5 = 4
</span>Since both numbers were multiplied by the same number, this is a true proportion.
The answer is D.
Answer:
2
Step-by-step explanation:
a cup detergent for 
a load of clothes would mean for each full load, it would take a cup of detergent.
Thus if you have 4 load of clothes, which is 8 half loads. You can take that 8 half loads and multiply by 8. This gives you 2 cups of detergent.
Answer:
The Trout will have to jump 49 cm in order to catch the insect
Step-by-step explanation:
Here, we want to calculate the distance the Trout has to jump in order to catch the Insect
To calculate this, we need to know the difference in the distances
From what we have, the Trout is 32 cm below the surface while the Insect is 17 cm above the surface of the lake
The difference in height which will represent the distance that the Trout has to jump to catch the insect will be ;
17 + 32 = 49 cm
11,400 seconds
You would take 3 hours to minutes which is 180 then add the following 10 minutes and convert it to seconds.
