Answer:
125
Step-by-step explanation:
Find the surface area of the table that Raj wants to cover.
Since the side table is a cube each side is identical.
Step 2:
Raj wants to cover 5 sides of the cube. Therefore the total surface area to be covered is 5 · 30 · 30 = 4,500 square inches.
Step 3:
Find the surface area of each tile.
The surface area of each tile is 6 · 6 = 36 square inches.
Step 4:
Find the number of tiles needed to cover the table.
4,500 square inches
36 square inches per tile
= 125 tiles
Raj will need 125 tiles to cover the table.
Answer:
The amusement park needs to pay at least $98.40 to 225 employees. So the minimum price they need to charge to pay all the employees is 98.40 x 225
Step-by-step explanation:
Profit minimum= employee pay x employee amount
98.40 x 225
After multiplication, profit minimum needs to be= $22140
Divide profit minimum by guests to get price per ticket
22140/1000 guests
$22.14= price of ticket for minimum profit
L=18
w=(1/3)18=6
idk if this is right but good luck

Answer:
yes
Step-by-step explanation:
The tower is about 50.1 meters tall. The guidebook is correct.
__
The distance from the base of the tower to the angle vertex is ...
d1 = h/tan(46°)
d2 = d1 +50 = h/tan(27°)
Then the height of the tower is ...
h/tan(46°) +50 = h/tan(27°)
50 = h(cot(27°) - cot(46°))
h = 50/(cot(27°) -cot(46°)) ≈ 50/(1.96261 -0.96569) ≈ 50/0.99692
h ≈ 50.1544 . . . meters
The tower is more than 50 meters high.
Answer:
The value of residual is 2.5131%.
Step-by-step explanation:
We are given the following in the question:
The above is a linear regression equation to predict the percentage of people in a state that would vote for Obama in 2012 based on the percentage of people in a state that voted for Obama in 2008.
Independent Variable:
Percentage of people in a state that voted for Obama in 2008
Dependent Variable:
Percentage of people in a state that would vote for Obama in 2012
In the state of Florida, 50.09% voted for Obama in 2008; whereas, 50.01% voted for him in 2012.
Thus, the actual value is 50.01%.
We predict the value from regression equation by putting x = 50.09
The predicted value for percentage of people in a state that would vote for Obama in 2012 is 47.4969%.
Residual is the difference between the predicted value and the actual value.
Thus, the value of residual is 2.5131%.
