Answer:
Step-by-step explanation:
Let x represent the amount that he paid for one hamburger.
Daniel buys lunch for his family from a food stand. He purchased one hot dog for $2.50 and 3 hamburgers. The cost of 3 hamburgers would be 3x.
If he spent a total amount of $13 on the hot dog and hamburgers, it means that
2.5 + 3x = 13
3x = 13 - 2.5 = 10.5
x = 10.5/3
x = $3.5
We determine first the real dimension of the circular fountain by using the scale factor given.
(18 cm) x (4 ft / 3 cm) = 24 ft
Then, calculate for the area of the base of the circular fountain by the equation,
A = πD²/4
where A is are and D is diameter. Substituting,
A = π(24 ft)²/4 = 144π ft² ≈ 452.4 ft²
Thus, the area of the base of the circular fountain is approximately 452.4 ft².
Answer:
3/4 written as a percent would be 75%
The measure of the convex arc is given by the following relationship:
WZ + 41 = ZWX
From here, we must clear We must replace the value of WZ.
The value of WZ is given by
WZ=180
We have then:
ZWX = 180 + 41
ZWX = 221 degrees
Answer:
the measure of convex arc upper ZWX is:
ZWX = 221 degrees
