Answer:
total = 96 sweets
Step-by-step explanation:
sweets shared in the ratio 4 : 5 : 7 = 4x : 5x : 7x ( x is a multiplier )
Seth got 18 more sweets than Frank , that is
7x = 4x + 18 ( subtract 4x from both sides )
3x = 18 ( divide both sides by 3 )
x = 6
Then
total = 4x + 5x + 7x = 16x = 16 × 6 = 96 sweets
Answer:
Angle 1, 2, 4 = 45 degrees
Step-by-step explanation:
2x+15 = x+30
-15 both sides
2x = x+15
-x both sides
x = 15
Plug x = 15 into x+30 or 2x+15
15+30 = 45
2(15)+15 = 45
Answer:
A control group is used in an experiment as a point of comparison.
Step-by-step explanation:
By having a group that does not receive any sort of treatment, researchers are better able to isolate whether the experimental treatment did or did not affect the subjects who received it.
The surface area would be 17.6ft2
Explanation:
2 x 1 x 1/2 = 1
2 x 1 x 1/2 = 1
3 x 1 = 3
3 x 2 = 6
3 x 2.2 = 6.6
6.6 + 6 + 3 + 1 + 1 = 17.6
Answer:
The number of distinguishable arrangements are 1,663,200.
Step-by-step explanation:
The word is: CONNECTICUT
The number of ways to arrange a word when no conditions are applied is:
Here <em>k</em> is the number of times a word is repeated.
In the word CONNECTICUT there are:
3 Cs
2 Ns
2 Ts
And there are a total of <em>n</em> = 11 letters
So, the number of distinguishable arrangements are:
Thus, the number of distinguishable arrangements are 1,663,200.
