The number of Snickers bar and KitKat bar bought is 95 and 109 respectively.
Cost of 48 Snickers = $28
Cost per one = $28/48
= $0.583
Cost of 36 KitKat = $22.50
cost per one = $22.50/36
= $0.625
let
x + y = 204 (1)
0.583x + 0.625y = 123.50 (2)
From (1)
x = 204 - y
substitute into (2)
0.583x + 0.625y = 123.50
0.583(204 - y) + 0.625y = 123.50
118.932 - 0.583y + 0.625y = 123.50
- 0.583y + 0.625y = 123.50 - 118.932
0.042y = 4.568
y = 4.568/0.042
y = 108.761904761904
Approximately,
y = 109
substitute into (1)
x + y = 204
x + 109 = 204
x = 204 - 109
x = 95

Answer: 96 snickers and 108 kitkats
Step-by-step explanation: you should do system of equations and then it would be 48s+36k=204 and 28s+22.5k=123.5, after you do the math, the answer turns out to be 96 snickers and 108 kitkats. :)
Answer:
Step-by-step explanation:
so 30% of the total number of goals shot is 5
30% of what number is 5....turn ur percent to a decimal..." of " is multiply
let the number of shots represent x
0.30x = 5...divide borh sides by 0.30
x = 5/0.30
x = 16.66 shots
Answer:
gºf(x) =
Step-by-step explanation:
Given
f(x) = x2
g(x) = 3x - 1
To find
gºf(x)
To find gºf(x) we will use value of f(x) = in place of in g(x)
lets do that
g(x) = 3x - 1
gºf(x) = 3(f(x)) -1
gºf(x) =
Thus, value of gºf(x) is .
The word form of the decimal number 0.76 is, Zero point seven six.
The standard decimal form of numbers is written in base 10 as there are 10 different numbers from 0 to 9.
Each digit has a face value and a place value.
Given, A decimal number 0.76.
Now, If it was just 76 we could pronounce it as seventy-six.
But it is decimal form and we know each digit after the decimal we pronounce it as a single digit.
Therefore, 0.76 in terms of words is, zero point seven six.

Hence surface area of figure is option d-174
The surface area of an object is the entire area filled by its surfaces. Varying 3D shapes have different surface areas in geometry, which may readily be determined using the formulas we'll learn in this lesson. The surface area is divided into two groups lateral and total.
the figure contains 3 , 3-d figures
one cube-3 m each,
1 cuboid-legth-9 m,height-3m-breadth-2 m,
1 cuboid- length-5 m, breadth-2m,height-2 m
hence surface area of 3 figures=
cube==24
cuboid=2(lb+bh+hl)=2(10+4+10)=48
cuboid=2(lb+bh+hl)=2(18+6+27)=102
add all we get =174
