Answer:
2.75 m²
Step-by-step explanation:
From the information given:
the thickness of the paint = 0.07 cm = (0.07/100) m
= 0.0007 m thick
the diameter hemispherical dome = 50 m
∴
radius of the dome = 50m /2 = 25 m
The volume of a hemispherical dome is expressed as:
Thus, the change in the volume now is:
∴
dV = 2π × (25)² (0.0007)
where;
dr = 0.0007
dV = 2π × (25)² (0.0007)
dV = 2.75 m²

Step-by-step explanation:
The pie chart will show that Claire spent about 33.3% of her time sleeping.
Answer:
195 yd²
Step-by-step explanation:
The area (A) of a rhombus is calculated as
A = half the product of the diagonals
one diagonal = 13 + 13 = 26, the other diagonal = 7.5 + 7.5 = 15, thus
A = 0.5 × 26 × 15 = 195 yd²
Answer:
y=4x+8
Step-by-step explanation:
I assume you want this rewritten in slope intercept form. That means we need to isolate the y.
-4x+y=-8
Add 4x to both sides
y=-8+4x
Now let's rewrite it in slope intercept form. Recall slope intercept form is y=mx+b. That means our 'b' (8) must be on the end of the equation.
y=4x+8
A. x = 25 - 4 / 1.5
B. x = 25 - 4 / 1.5
x = 21 / 1.5
x = 14
Daniel can go on 14 rides. He originally has $25 to spend. He pays $4 just to get in, leaving him with $21. Each ride costs $1.50, so divide $21 by $1.50 to find how many rides he can afford.
