Answer:
CHEEEEEEEEESE
Step-by-step explanation:
The answer would be 105.41
Explantaion: 122 • 0.2=24.4
122-24.4=97.6
97.6•0.08=7.808 which rounded to the nearest hundredths would be 7.81 then 97.6+7.81=105.41
Answer:
Step-by-step explanation:
Total percentage = 100%
And we know that proportions of Vanilla +chocolate +strawberry = 100%
Proportion of Vanilla = 45%
Proportion of Strawberry = 1/4 *100 = 25%
Let proportion of chocolate be represented by variable C;
So, 45% +25% + C = 100%
65% +C = 100%
Subtract 65% from both sides to solve for C;
C=100% - 65%
C = 35%
Therefore there is 35% of chocolate in the shop.
A = pi × r²
3.14 x 2²
3.14 x 4
A = 12.56636 ≈ 12.56
hopefully this helps u and if u know the formula to solve it, it is super easy
Answer:
-3+2sqrt7
-3-2sqrt7
Step-by-step explanation:
x^2+6x-9=10
x^2+6x-9-10=0
x^2+6x-19=0
ax^2+bx+c=0
a=1 b=6 c=-19
As cannot be solved by completing square we will use quadratic equation
x= (-b+sqrt(b^2-4ac))/2a and x= (-b-sqrt(b^2-4ac))/2a
x= (-6+sqrt(6^2-4*-19))/2 and x= (-6-sqrt(6^2-4*-19))/2
x=(-6+sqrt(36+76))/2 and x=(-6-sqrt(36+76))/2
x=(-6+4sqrt7)/2 and x=(-6-4sqrt7)/2
x=(-3+2sqrt7) and x=(-3-2sqrt7)
x=2.29 and x= -8.29
