Problem 11
Answer: 339 square meters---------------
Work Shown:
The surface area of a 3D sphere is 4pi*r^2. So a hemisphere has surface area 2pi*r^2 since we cut the surface area in half.
Plug in r = 6 (half of the diameter 12) and we get 2pi*r^2 = 2pi*6^2 = 72pi
Now consider the circle with radius r = 6. Its area is pi*r^2 = pi*6^2 = 36pi
Add the two areas and we get 72pi+36pi = 108pi
Lastly, use your calculator to get 108pi = 108*3.1415926535898 = 339.292006587699 which rounds to 339
======================================
Problem 12
Answer: C) 19.5 mm---------------
Explanation:
Look at where the "0" in the bottom sliding portion lines up with the number scale above. That "0" is between 19 and 20 mm. So you could argue that 19.2 and 19.5 are both valid answers, but I think 19.5 is the better answer since the tickmark seems to be right in the middle (more or less).
Step-by-step explanation:
surface area of hemisphere =3πr²
=3*3.14(6)²
=339.12m²
diameter of pipe= 19.5mm
from the set ( 1,2,3,4,5), which values make n+1>4 true?
- (1,2)
- (4,5)
- (3,4,5)
- (1,2,3)
Answer:
(4,5)
Step-by-step explanation:
n+1>4
subtract 1 from both sides
n>3
that means n is greater than 3 so 3 is not a solution but everything higher than 3 is true.
A balloon is floating above a lake and a sunken canoe is below the surface of the lake. The balloon's vertical position is 12 meters and the canoes is -4.8 meters. The equation 12+d=-4.8 represents the situation.
Answer:
i. The distance between the balloon and canoe is 16.8 meters.
ii. The situation can be represented by: -12 + d = 4.8
Step-by-step explanation:
Let the surface of the lake be zero. Then any position above it is taken to be positive, while any position below is taken as negative.
So that,
the balloon's vertical position = 12 meters
the sunken canoe's position = -4.8 meters
Given that the distance between the balloon and the canoes is d, then:
d = balloon's position - canoe's position
= 12 - (-4.8)
= 12 + 4.8
d = 16.8
The distance between the balloon and canoe is 16.8 meters.
Thus,
d = 12 -(-4.8)
d = 12 + 4.8
-12 + d = 4.8
The situation can be represented by: -12 + d = 4.8

chris spends 35% of his budget on rent for his apartment, Write this percent as a fraction, percent and a decimal. helpp asap
Answer:
Please check the explanation.
Step-by-step explanation:
Given that Chris spends 35% of his budget on rent for his apartment.We need to write 35% as a fraction, percent, and a decimal.
35% as a fraction:
All we need is to divide 35 by 100 as 35 is basically the 35th part of 100 parts.
Thus, 35% as a fraction would be: 35/100
35% as a decimal:
All we need is to divide 35 by 100 and calculate the result such as:
35/100 = 0.35
Thus, 35% as a decimal would be: 0.35
35% as a percent:
35% is already mentioned as a percent.
Thus, 35% as a percent would be: 35%
arianne is taking a geometry course and is working with the area of triangles. she knows the area and the height but needs to find the base. rearrange the following equation for b, where a is the area, b is the base, and h is the height of the triangle. a
Base is 2 times A over height= [tex](base)=\frac{2Area}{height}[/tex].
Area is the amount of space occupied by a two-dimensional figure. In other words, it is the quantity that measures the number of unit squares that cover the surface of a closed figure.
Area of a triangle is given by the formula;
[tex]A=\frac{1}{2} base * height[/tex]
Now, we need to solve for b. We multiply the right side, cross multiply, and follow rules of algebra to isolate b. Shown below:
[tex]A=\frac{1}{2} base*height\\A=\frac{bh}{2} \\2A=bh\\b(base)=\frac{2A}{h}[/tex]
Thus, Base is 2 times A over height= [tex](base)=\frac{2Area}{height}[/tex].

Joyce paid $117.00 for an item at the store that was 35% off the original price. What was the original price? Round your answer to the nearest cent.
I just need the explanation.
Considering the definition of an equation and the way to solve it, the original price was $180.
Definition of equationAn equation is the equality existing between two algebraic expressions connected through the equals sign in which one or more unknown values appear in addition to certain known data.
The solution of a equation means determining the value in which the equality must be true. To solve an equation, keep in mind:
When a value that is adding, when passing to the other member of the equation, it will subtract.If a value you are subtracting goes to the other side of the equation by adding.When a value you are dividing goes to another side of the equation, it will multiply whatever is on the other side.If a value is multiplying it passes to the other side of the equation, it will pass by dividing everything on the other side.Original priceBeing "x" the original price, and knowing that:
Joyce paid $117.00 for an item at the store.The item was 35% (0.35 expressed as a decimal number) off the original price.The original price can be calculated through the equation:
x - 0.35x= 117
Solving:
(1 - 0.35)x= 117
0.65x= 117
x= 117 ÷ 0.65
x= 180
Finally, the original price was $180.

If a circle has equation (x-3)^2 + (y+1)^2 = 49, what is it’s domain?
I’m forgetting everything from algebra
The domain of the circle is [-4, 10]
How to determine the domain of the circle?The circle equation is given as:
(x - 3)^2 + (y + 1)^2 = 49
Express 49 as 7^2
So, we have
(x - 3)^2 + (y + 1)^2 = 7^2
The general circle equation is
(x - a)^2 + (y - b)^2 = r^2
Where the domain is
Domain = [a ± r]
So, we have
Domain = [3 ± 7]
Evaluate
Domain = [3 - 7, 3 + 7]
This gives
Domain = [-4, 10]
Hence, the domain of the circle is [-4, 10]

find the value of x (9x-3)
The result of the multiplication is the value of x (9x-3) is: 9x² - 3x.
Here, we have,
given that,
the expression is: x (9x-3)
now we need to find the value of x (9x-3)
we have,
x (9x-3)
=> x × (9x-3)
so, we have to multiply this two terms.
now, we get,
=> x × (9x) - x × 3
=> 9x² - 3x
Hence, The result of the multiplication is the value of x (9x-3) is: 9x² - 3x.

Because BC is a mid segment
Answer:
10
Step-by-step explanation:
These are similar triangles, which means that the ratio between 16 to 8 will equal x+10 to x. This could be written out as 16/8 = x+10/x. 16/8 is 2, which means that x+10 is twice the amount of x. We can write this out as 2x = x+10. We can then simplify this and get x = 10
