Answer:
$5
Step-by-step explanation:
Given data
We are given that
Large lemonade= $6
Small lemonade= $4
Total amount = 6+4= $10
He keeps 50% of the total
= 50/100*10
=0.5*10
= $5
Hence he will keep $5
F(x) = 2x + 4
f(x-5) shifts (fx) five units to the right, then
f(x-5) = 2(x-5) + 4 = 2x - k
2x - 10 + 4 = 2x - k
k = 6
Answer:
A triangle with three angles that each measure between 0º and 90º.
A triangle with one angle that measures between 90º and 180º.
A triangle containing a right angle.
Answer:
C = 62.8 m
Step-by-step explanation:
The circumference formula is C = πd.
Here d = 20 m. Therefore, the circumference of this circle is C = (20 m)π.
To the nearest 10th, we round off C = (20 m)(3.14159) = C = 62.8 m
