Answer:
Choice C
Step-by-step explanation:
f: initial value of 200 decreasing at a rate of 4%
g: initial value of 40 increasing at a rate of 8%
f is decreasing so it must go down starting at 200
That eliminates a and d
g is increasing and starts at 40 That eliminates a
We must look at b and c
g is increasing faster than f is decreasing
Choice C
25% for 90deg
15% for 54deg
10% for 36deg
All I did was put the degree number over 360 and moved the decimal place to the right twice :)
Answer:
49 and 118
Step-by-step explanation:
Let the two numbers be x and y
x+y = 167
y = 3x-29
Substitute into the first equation
x+ 3x-29 = 167
Combine like terms
4x - 29 = 167
add 29 to each side
4x = 167+29
4x = 196
Divide by 4
4x/4 = 196/4
x = 49
x+y = 167
49+y = 167
y = 167-49
y =118
<span>The expression for the total price paid for all snacks (P pence)= 4n Pence
will be; P=4n.
Calculation:
let the total price for the four snacks be P pence.
let the four snacks be s1,s2,s3, and s4;
their prices are:
s1=n pence; s2= n pence; s3=n pence; s4= n pence.
therefore;
the total price paid for all snacks (P pence)= s1 price +s2 price +s3 price +s4 price = n+n+n+n= 4n
hence; P=4n
i.e. the total price paid for all snacks (P pence)= 4n Pence</span>
