[tex] \frac{ {n}^{2} }{2} [/tex]
Step-by-step explanation:
[tex] \frac{3 {n}^{5} }{6 {n}^{3} } = \frac{3}{6} \times \frac{ {n}^{5} }{ {n}^{3} } = \frac{1}{2} \times {n}^{5 - 3} = \frac{1}{2} \times {n}^{2} = \frac{ {n}^{2} }{2}[/tex]

Answer:
Step-by-step explanation:
5. 3/4 +3/4 + 3/4 + 3/4 + 3/4 + 3/4 = (6 x 3)/4 = 18/4 = 4 1/2
6. 16 x 3 x 1/8 = (48x 1)/8 = 48/8 = 6
7. 500 x 2/5 = 500 x 2 x 1/5 = (1000 x 1)/5 = 1000/5 = 200
what 5/8x + 1/2 (1/4x + 10)?
Answer:
3/4x + 5
Step-by-step explanation:
5/8x + 1/2 ( 1/4x + 10) = 5/8x + 1/8x + 5 = 6/8x + 5 = 3/4x + 5
At the school carnival, Jade has a game booth with a spinner. The banner at her booth reads "20% chance of winning!" What is the chance that a player may not win? (5 points) Group of answer choices 90% 50% 80% 40%
Answer: 80%
Step-by-step explanation:
100% chance is normally the most so 100 is our whole. 100-20=80. That being the % makes 80% as the answer. Hope i helped!

Helen plays basketball. For free throws, she makes the shot 75% of the time. Helen must now attempt two free throws. The probability that Helen makes the second free throw given that she made the first is 0.85. What is the probability that she makes both free throws?
Answer: 0.6375
Step-by-step explanation:
Let's assume that the event that she'll make the first shot is given as P(A) while making the second shot is P(B). Therefore, P(A/B) = 0.85
Therefore, the probability that she makes both free throws will be denoted as:
= 0.75 × 0.85
= 0.6375
A sno-cone machine priced at $139 is on sale for 20% off. The sales tax rate is 6.75%. What is the price of the sno-cone machine after the discount and sales tax?
Answer:
$127.03
Step-by-step explanation:
A snow cone machine price at $139 is on after for 20 off.
The price after discount=139-20=$199
The sale tax rate 6.75%
Price with sales tax=199+(6.75%×199)
=199+(0.0675×199)
= 199+8.03
=$127.03

Suppose an upward force of 15 N is added to the box. What will be the net vertical force on the box?
Answer:
Step-by-step explanation:
Suppose an upward force of 15 N is added to the box. What will be the net vertical force on the box?
THIS IS THE COMPLETE QUESTION BELOW;
1. Explain how you calculate the net force in any direction on the box.
2. Suppose an upward force of 15 N is added to the box. What will be the net vertical force on the box?
3. What force could be applied to the box to make the net force in the horizontal direction zero? Explain.
4. Suppose a force of 25 N to the right is added to the box. What will be the net force to the right?
CHECK THE ATTACHMENT FOR THE FIQURE.
1)since the given horizontal forces are acting on the box at opposite direction then
NET FORCE= (100- 50)N
= 50N( this is because the 100N and 50N acting Horizontally will cancel each other, then the remaining force is 50N.
✓Since, the two vertical forces also acted on the box in opposite direction, then
NET FORCE= (25 25)N
= 0N
Note: horizontal forces are one acting from right to left and vice versa, while vertical forces are ones acting from up to down and vice versa.
HENCE, NET FORCE = 50N + 0N= 50N
2) since the net vertical force was 0N, if
15N force is added then we still have NET FORCE OF 15N
3) if force of 50N is applied to horizontal forces moving from left to right then NET HORIZONTAL FORCES= 0N
4) since, the net force for the box is 50N, if Horizontal force of 25N is added moving left to right then NET FORCE = 25N for whole box.

Calculate the area of the trapezoid
Answer:
180 in^2
Step-by-step explanation:
area = 5(sq rt 75) x (sq rt 27) - [5(sq rt 75)-5(sq rt 27)] x 3(sq rt 3) x 0.5
area = 180 in^2
solve for x or find x
Answer:
x = 18
Step-by-step explanation:
diagonals bisect each other so 12x = 216
x = 216/12
x = 18

I need only help on 11-14 please someone help me
Linear function definition: a function that will create a straight line when graphed.
11 is not a linear function (not a straight line), but 12 is.
For the tables, you can either plot out the graph or just look at the number patterns. A linear function's numbers will always increase/decrease accordingly at a constant rate. For example, in 14, you notice that as x increases by 1, y decreases by 2. This means it is a linear graph.
In 13, as x increases by 1, the output y increases but at a different rate each time. It increased by 3 at first, then 5, then 7. Hence, it is not a linear function. What is it then? It is an exponential function.
Please help me I don’t know what to do
14. A right cone has a height of 14 in and a base diameter of 17 in.
a Sketch and label a diagram of the cone
b. Determine the area of the lateral surface of the cone, to the nearest square inch
Given:
The height of a right cone = 14 in
Base diameter = 17 in
To find:
The diagram of the cone and its lateral surface area.
Solution:
(a)
The diagram of a right cone with height 14 in and base diameter of 17 in is shown below.
Diagram is not to scale.
(b)
We know that lateral surface of the cone is
[tex]A=\pi rl[/tex]
[tex]A=\pi r\sqrt{r^2+h^2}[/tex] ...(i)
Where, r is the base radius, h is vertical height and l is the slant height of the cone.
Base radius of the cone = [tex]\dfrac{\text{Base diameter}}{2}[/tex]
[tex]r=\dfrac{17}{2}[/tex]
[tex]r=8.5[/tex]
Now,
Putting r=8.5, h=14 and π=3.14 in (i), we get
[tex]A=(3.14)(8.5)\sqrt{(8.5)^2+(14)^2}[/tex]
[tex]A=26.69\sqrt{72.25+196}[/tex]
[tex]A=26.69\sqrt{268.25}[/tex]
[tex]A=437.1379[/tex]
[tex]A\approx 437[/tex]
Therefore, the lateral surface area of the cone is 437 sq. inches.

Rizwan has 100 ruppees . He spent rs 25 in ice cream . Rs 45 on pizza, and the rest on other things . What percantage did he spend on other things .
Answer:percantage spent on other things = 30%
Step-by-step explanation:
Percentage spent on other things = Money spent on other things/ Total money x `100/ 1
Money spent on rest things = Total money - ( Money spent on ice cream + Money spent on pizza)
100 -(25+ 45)
100-70= Rs 30
Percentage spent on other things = Money spent on other things/ Total money x `100/ 1
= Rs 30/ Rs 100 x 100
0.3 x 100 = 30%
A UFO is coming in to pick up some test subjects. Their elevation above the ground is 60,000 feet. Their laser sights tell them that a direct (diagonal) path to the nearest landing area is 90,000 feet away. What is the angle of depression as they come in to land?
Answer:
41.83°
Step-by-step explanation:
It is given that :
The vertical distance of the UFO from the ground = 60,000 feet
The diagonal distance of the landing area to the UFO = 90,000 feet
In order to find the angle of depression, we have to use the trigonometric ratios, i.e.,
[tex]$\sin \ \theta = \frac{\text{perpendicular distance}}{\text{hypotenus}}$[/tex]
[tex]$\sin \ \theta = \frac{60,000}{90,000}$[/tex]
[tex]$\sin \ \theta = \frac{2}{3}$[/tex]
[tex]$\sin \ \theta = 0.667$[/tex]
∴ [tex]$\theta = \sin^{-1 }(0.667)$[/tex]
= 41.83°
Martina bought 4 CDs that were each the same price. Including sales tax, she paid a total of $70.40 . Each CD had a tax of $ 1.10 . What was the price of each CD before tax?
[tex]1.10 \times 4 = 4.40[/tex]
[tex]70.40 - 4.40 = 66[/tex]
[tex]66 \div 4 = 16.5[/tex]
Each CD was $16.50 before tax
Proof
[tex]total \: cost = 16.5(4) + 1.10(4)[/tex]
[tex]total \: cost = 66 + 4.40[/tex]
[tex]total \: cost = 70.40[/tex]
