Answer:
22in²
Step-by-step explanation:
According to the scenario, computation of the given data are as follows,
Circumference = 25 (1/7)
As we know,
Circumference of a circle = 2πr
By solving this we get
Radius (r) = 4in
Now. we can calculate the area by using following formula,
Area = πr²
By putting the value, we get
Area = (22/7) × 4²
= 22/7 × 16
= 352÷16
Area = 22in²
Answer:
-0.2
Step-by-step explanation:
5.2 + 6.3 = 11.5
11.5 - 12 / 2.5
-0.5 / 2.5
= -0.2
Step-by-step explanation:
there are 35 in total.
4 go into one box.
so, how many in 8 boxes ?
well, 4×8 = 32
what is the difference between 32 and 35 ?
35 - 32 = 3
so, 3 models are still left.
Answer:
It's -32x^2
Step-by-step explanation:
Answer:
one tin of cheese $23
one tin of caramel $27
Step-by-step explanation:
let 'x' = cost of cheese tin
let 'y' = cost of caramel tin
10x + 8y = 446
22x + 11y = 803
i multiplied the first equation by -11 and the second by 8 to eliminate the 'y' terms
-110x - 88y = -4906
+ <u>176x + 88y = 6424</u>
66x = 1518
x = 1518 / 66
x = 23
find 'y': 10(23) + 8y = 446
230 + 8y = 446
8y = 216
y = 27
