Answer:
200
Step-by-step explanation:
25 percent is known to be 1/4 of a number, so if 50 teachers represent 1/4 of all the teachers, that means that in order to get a full number, we must multiple 50 by 4 in order to get all 100% of the teachers.
By doing 50x4, we can conclude that 200 teachers teach at the school (aka 100% of all teachers)
Answer:
48.2 cm
Step-by-step explanation:
The bottom side of the large triangle has length 78 cm.
The bottom side of the right triangle has length 78 cm/2 = 39 cm.
Now we use the Pythagorean theorem to find the vertical side, the spine.
39² + s² = 62²
s² = 3844 - 1521
s² = 2323
s = 48.2
Answer: 48.2 cm
2*5=10/3
10/3=3.33
two times 5 equals 10
1 times 3 equals 3
10 divided by 3 equals 3.33
Answer:
1/6
Step-by-step explanation:
Let
c-----> the number of cola bottles that Dan picks
s ----> the number of smarties that Dan picks
m ---> the number of marshmallows that Dan picks
we know that
c=3s ----> equation A
m=2s ---> equation B
we know that
To find out the proportion of the bag of sweets that are smarties, divide the number of smarties by the total of sweets
The total of sweets is equal to
(c+s+m)
substitute equation A and equation B in the total of sweets
(3s+s+2s) =6s
Find the proportion
s/6s
Simplify
1/6
