Answer:
8 + 2w
Step-by-step explanation:
⇒ Change all signs to addition (subtraction is the same as adding a negative):
5 + 3w + 3 + -w
⇒ Since the expression is now all addition, you can rearrange them in any order. So group the terms together by their type:
5 + 3 + 3w + -w
⇒ Simplify:
8 + 2w
Answer: 8 + 2w

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.

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
Your family goes to a Southern-style restaurant for dinner. There are 6 people in your family.
Some order the chicken dinner for $14 and some order the steak dinner for $17. If the total bill
was $99, how many people ordered each dinner?
Answer:
We conclude that:
The number of people who ordered the chicken dinner = 1The number of people who ordered the steak dinner = 5Step-by-step explanation:
Given that
Some order the chicken dinner for $14some order the steak dinner for $17.Total bill = $99Let 'n' be the number of people who ordered the chicken dinner.Let '6-n' be the number of people who ordered the steak dinner.Thus, the equation becomes
[tex]14n + 17(6-n) = 99[/tex]
[tex]14n + 102 - 17n = 99[/tex]
[tex]-3n = 99 - 102[/tex]
[tex]-3n = -3[/tex]
Divide both sides by -3
[tex]n = 1[/tex]
and
[tex]6-n = 6-1 = 5[/tex]
Therefore, we conclude that:
The number of people who ordered the chicken dinner = 1The number of people who ordered the steak dinner = 5If 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]

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.

Step-by-step explanation:
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.

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

Step-by-step explanation:
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].

There are 3 red marbles, 2 blue marbles, and 7 black marbles if you choose one marble, what is the probability that it will be a red marble?
Answer:
3:12
Step-by-step explanation:
3 + 2 + 7 = 12
3 = red marbles
12 = total marbles
Answer:
Probability of both red =3(182)=3(18!2!16!)=3153
Step-by-step explanation:
Let Ai be the event in which the i-th ball you grab is red. For the first ball you choose, you have 3 red marbles out of a total of 18. Therefore,
P(A1)=318.
For the second marble you grab, given that you already took a red one, that is, given A1, you have 2 red balls out of a total of 17, then
P(A2∣A1)=217.
Finally,
P(A1∩A2)=P(A1)P(A2∣A1)=318217=151.
