Answer:
Jordan got 222 calories from pizza
Step-by-step explanation:
Given:
slices of pizza ate by Kasey =10
cups of fruit salad by Kasey= 5
slices of pizza ate by Jordan = 6
cups of fruit salad by Jordan= 7
Kasey's calorie count = 3070
Jordan calorie count = 2522
To Find:
calories Jordan got from pizza =?
Solution:
Let the calorie of one slice of pizza be x
and the calorie of one cup of fruit salad be y
According to the question, the equation that represents the Kasey's Scenario is
10x + 5y = 3070-------------------------------------(1)
Similarly the equation that represents the Jordan Scenario is
6x + 7y = 2522--------------------------------------(2)
multiply eq(1) by 6 we get
60x + 30y = 18420---------------------------------(3)
multiply eq(2) by 10 we get,
60x + 70y = 25220----------------------------------(4)
Subtracting eq (3) from (4) we get
60x + 70y = 25220
60x + 30y = 18420
(-) (-) (-)
-----------------------------------
0x + 40y = 6800
---------------------------------
=>40 y = 6800
=>y =
=> y = 170
So calorie of one cup fruit salad is = 170 calories
substituting the y values in eq 1 we get
10x + 5(170) = 3070
10x + 850 = 3070
10x = 3070 - 850
10x = 2220
x =
x= 222
So calorie of one pizza slice = 222 calories
Now we know that Jordan ate 6 slices of pizza
calories Jordan get from pizza = number of pizza he ate X calore per pizza slice
=> 6 x 222
=>1332 calories
Answer:
277,200
Step-by-step explanation:
To find the number of permutation we can form from the letters of the word "engineering", we first need to find the frequencies of the different letters present.
E = 3
G = 2
N= 3
I = 2
R = 1
Now that we have the frequencies, we count the number of letters in the word "engineering".
E N G I N E E R I N G
11 letters
Now we take the factorial of total number of letters and divide it by the number of repeats and their factorial
So we get:
We remove the 1! because it will just yield 1.
So the total number of permutations from the letters of the word "engineering" will be:
Total number of permutations =
Total number of permutations = 277,200
