A cube of side 14 cm is surmounted by a hemisphere. What is the greatest diameter the hemisphere can have? Find the surface area of the solid?
Answer:
Greatest diameter of hemisphere = 14 cm
Surface area of solid = 1330 cm²
Step-by-step explanation:
Side of the cube (a) = 14 cm
If a cube is surmounted (placed right over its top) by a hemisphere, then that means that the greatest diameter of the hemisphere will be equal to the measure of the edge of the cube (a cube has equal sides). Hence, the greatest diameter of the hemisphere is 14 cm & the radius (r) will be 14/2 = 7 cm (radius = ½ diameter)
Now, we need to find the surface area of the solid.
Here, the solid comprises of a cube & a hemisphere sharing a same circular base area. Hence,
Surface area of the solid
= Surface area of cube + Curved surface of hemisphere - Circular base area
= 6a² + 2πr² - πr²
= 6a² + πr²
= 6(14)² + 22/7×(7)² [π = 22/7]
= 1176 + 154
= 1330 cm²

Answer:
Day 44
Step-by-step explanation:
Given function:
[tex]f(t)=500t^2[/tex]
where:
f = number of daily hitst = times (in days)To find the day on which the number of daily hits reaches 1,000,000, set the function to 1,000,000 and solve for t:
[tex]\begin{aligned}f(t) & =1000000\\ \implies 500t^2 & = 1000000\\ t^2&=\dfrac{1000000}{500}\\ t^2 & = 2000\\ t & = \pm \sqrt{2000}\\ t & = \pm 44.72135955...\end{aligned}[/tex]
As time in positive, t = 44.72135955 only.
This tells us that the number of daily hits reaches 1,000,000 during the 44th day.

The line of best fit shows that Luther can expect the speed to be 51 miles/hour when he throws 80 pitches and 64 miles/hour when he throws 54 pitches.
How to calculate the speed?The average speed of Luther's pitches when he throws 80 pitches will be:
y = -0.511x + 91.636
= -0.511(80) + 91.636
= 50.756
= 51
Also, the number of pitches that Luther can throw when the speed is 64 miles per hour will be:
y = -0.511x + 91.638
64 = -0.511x + 91.638
0.511x = 91.638 - 64
0.511x = 27.636
x = 54
Therefore, the number of pitches will be 54.

Calculate the cost (omit commission) of buying the 500 shares of Delta Air at $50.61.
Multiplication is the process of multiplying, therefore, adding a number to itself for the number of times stated. The cost of 500 shares of Delta Air is $25,305.
What is multiplication?Multiplication is the process of multiplying, therefore, adding a number to itself for the number of times stated. For example, 3 × 4 means 3 is added to itself 4 times, and vice versa for the other number.
The cost of a single share is $50.61, therefore, the cost of 500 shares will be,
Cost of 500 shares = 500 × cost of single share
= 500 × $50.61
= $25,305
Hence, the cost of 500 shares of Delta Air is $25,305.

(4 questions) Is 8km greater than 8000mm? Is 50km greater than 5000m? Is 10m greater than 100cm? (last one) Is 4mm greater than 40cm?
Answer:
1. 8000mm is the same as 8 metres. So 8km is greater than 8000mm
2. 5000m is the same as 5 km. So 50 km is greater than 5000m
3. 100cm is the same as 1 m. So 10m is greater than 100cm
4. 40 cm is the same as 400mm. So 4mm is less than 40cm.

The measure of the angle BAC is 72degrees
We have given that the
angle B=108 degrees and angle C=60 degrees.
We have to determine angle A
In parallelogram
What is the sum of the two angles?The sum of the two angles is 180 degrees.
Therefore we get,
angle A+ angle B=180 degrees
angle B=108 degrees
angle A +108=180
angleA=180-108
angleA=72 degrees.
Therefore the measure of the angle A is 72degrees

Kyle competes in 100 m wheelchair races. Hel
calculates the information below using his last 4
race times.
His minimum race time was 19.8 s.
The range of his race times was 5.6 s.
The median of his race times was 23.8 s.
The mode of his race times was 25.4 s.
If Kyle includes a new race time of 25.7 s in his
calculations, how much will the mean change
by?
Answer:
0.5s
Step-by-step explanation:
His initial mean would be calculated by:
His minimum race time = 19.8s
The maximum race time = 19.8 + 5.6 = 25.4s
Since the mode is also 25.4, there are 2 25.4s races.
Since the median is 23.8s and the number of race times is even, the final race time can be calculated by:
25.4- 23.8s = 1.6s
23.8-1.6 = 22.2s
So the race times are 19.8s, 22.2s, 25.4s and 25.4s.
This means that his initial mean was (19.8+22.2+25.4+25.4)/4 = (42+50.8)/4= 92.8 /4 = 23.2s
With the new race time, the equation will change to (92.8+25.7)/(4+1)= 118.5/5= 23.7s
So the mean change would be 23.7 - 23.2 = 0.5 s.

FIND THE VALUE OF X
123°
Step-by-step explanation:Finding the Missing Angle Within the Triangle
We know that all triangles sum to 180 degrees. So, to find the missing angle within the missing angle, we can create an equation. For the purposes of this equation, I will use y as the missing angle within the triangle.
[tex]180=55+68+y[/tex]Then, solve for y by subtracting 55 and 68 from both sides.
[tex]57=y[/tex]Finding X
The missing angle within the triangle is supplementary to the x angle. Supplementary angles are angles that sum to 180. So, to find x we can create a new equation.
[tex]180=57+x[/tex]Next, solve the formula by subtracting 57 from both sides.
[tex]123=x[/tex]Shortcut
In cases like this, there is a shortcut that can be used. This shortcut can be used when you are trying to find a supplementary angle outside of a triangle, and you are given the other 2 angles of triangle. The x value will always be equal to the sum of the 2 angles that are not adjacent to the missing, outside angle.
So, in this case, [tex]x=68+55[/tex] because 68 and 55 are not adjacent to the outside angle, x.
Anna ordered a large pizza with 2 toppings. What was the total cost of her pizza? Show your equation and the total cost.
Answer: $15.49.
Step-by-step explanation: So far, her pizza already costs $13.99 because she chose large. However, she also ordered two toppings for $0.75 each, which is $1.50. We need to add $13.99 and $1.50 to find out the total cost of her custom pizza.
$13.99 + $1.50 = $15.49.
Therefore, the total cost of her pizza is $15.49.
