find the lateral surface area of the prism. geometry hw
Answer:
250
Step-by-step explanation:
Hello There!
The prism shown is a pentagonal prism
And we need to find the lateral surface area ( pretty much area of everything except for the bases.)
We can calculate the lateral surface area by using this formula
[tex]la=5ah[/tex]
where a (on the right hand side) equals the base edge length and h = height
(btw the 5 represents the number of sides)
so the base edge length of the shown figure is 5 and the height is 10
having found this information we plug it into the formula
[tex]la=5*5*10\\10*5=50\\50*5=250[/tex]
so we can conclude that the lateral surface area of the shown pentagonal prism is 250 cm²
If ∆SDE ~ ∆SWT, find WT.

One of the ending substances was a pink liquid. This ending substance is made up of the repeating group of atoms shown above. Which of the diagrams to the left shows the repeating groups of atoms that make up the samples the chemist mixed together?
Answer:
Its C
Step-by-step explanation:
Diagram c to the left shows the repeating groups of atoms that make up the samples the chemist mixed together.
What is atoms?Atoms are the smallest unit of matter that make up all physical objects. Atoms are composed of three main components: protons, neutrons, and electrons. Protons and neutrons are found in the nucleus of the atom and have a positive charge, while electrons orbit the nucleus and have a negative charge.
here, we have,
we know that,
Atoms can join together to form molecules, which are the building blocks of all matter. Atoms of different elements can join together in different ways to form compounds and these compounds are the basis of all substances. Atoms are also the basis of all chemical reactions and can exist in different physical states, such as solid, liquid, or gas. Atoms can also be combined to form isotopes, which are atoms of the same element with different numbers of neutrons.

The length of the arc which subtends an angle 60° at
the centre of a circle of radius 3 cm is approximately
Answer:
π cm
Step-by-step explanation:
The formula for arc length (s) as a function of radius (r) and central angle Ф (in radians) is s = rФ.
In this problem r = 3 cm and Ф = 60°, and so the arc length subtended is
s = (3 cm)(π/3) = π cm

Please HELP ASAP!!! The dot plot show the number of hours teenagers spent on two different websites last week. Which statement is supported by the data in the dot plots? (F.) the mode of the data for website K is greater than the mode of the data from website L. (G.) the range of the data for website L is equal to the range of data for website K. (H.) the distribution of data for website L is symmetrical. (J.) the distribution of data for website K is skewed to the left.
Answer:
(F.) the mode of the data for website K is greater than the mode of the data from website L
Step-by-step explanation:
Mode simply means the parameter that occurs the most.
In website K, the one that occurs the most is 8 hours while in website L, the one that occurs the most is 2 hours.
This means that mode of website K is greater than that of website L.
Thus,statement F is correct
Range is the difference between the highest value and the lowest value..
For website K, Range = 14 - 1 = 13
For website L, Range = 13 - 1 = 12
Thus,range of both websites are not the same and as such statement G is wrong.
For a symmetrical distribution, the left and right hand sides of the centre value line of the distribution have to mirror each other.
In this case neither website K nor L have that. Thus, statement H is not correct.
Skewed to the left means that more o
dot points are found to the left of the graph.
For website L, more dot points are located to the left while for website K, it's not the case. Thus, statement J is not correct

Sophomore, junior, and senior students at a high school will be surveyed regarding a potential increase in the extracurricular student activities fee. There are three possible responses to the survey question...agree with the increase, do not agree with the increase, no opinion. A chi-square test will be conducted to determine whether the response to this question is independent of the class in which the student is a member. How many degrees of freedom should the chi-square test have? A9 B6 C4 D2 E1
Answer: C) 4
Step-by-step explanation:
The chi-square test should have 4 degrees of freedom
The categories of students are:
Sophomore, junior, and senior students
The categories of response are:
.agree with the increase, do not agree with the increase, no opinion
There are three (3) categories of students and three (3) categories of response.
So, the degrees of freedom is calculated as:
[tex]df = (r -1) * (c -1)[/tex]
Where:
r = 3 i.e. categories of students
c = 3 i.e. categories of response.
This gives
[tex]df = (3 -1) * (3 -1)[/tex]
[tex]df = 2 * 2[/tex]
[tex]df = 4[/tex]
Hence, the chi-square test should have 4 degrees of freedom

The trajectory of a golf ball in a chip from the rough has a parabolic pattern. The height, in feet, of the ball is given by the equation h(x)=−.15x2+3.2x, where x is the number of feet away from the golf club (along the ground) the ball is.
The ball reaches a maximum height of _______ feet at a horizontal distance of ____
feet away from the golf club it was hit with.
The ball returns to the ground at about ________ feet away.
9514 1404 393
Answer:
maximum height of 17.07 feet about 10.67 feet from the club
returns to the ground 21.33 feet away
Step-by-step explanation:
A graphing calculator can answer these questions easily.
The vertex of the quadratic ax²+bx+c is given by x=-b/(2a). For this quadratic function, the highest point is found at ...
x = -(3.2)/(2(-0.15)) = 32/3 = 10 2/3 . . . . feet horizontally from the club
The maximum height is the function value at that point.
h(10 2/3) = (-0.15(10 2/3) +3.2)(10 2/3) = 1.6(10 2/3) = 17 1/15
The ball reaches a maximum height of 17 1/15 feet at a horizontal distance of 10 2/3 feet from the club. The ball's flight is symmetrical about the peak, so it returns to the ground about 21 1/3 feet away.

what are the real solutions to the equation 5x2 + 29x + 20 = 0?
Answer:Solutions are: x = -5, x = -4/5.
Step-by-step explanation:
Answer: -30/29
Step-by-step explanation: Let's solve your equation step-by-step.
(5)(2)+29x+20=0
Step 1: Simplify both sides of the equation.
(5)(2)+29x+20=0
10+29x+20=0
(29x)+(10+20)=0(Combine Like Terms)
29x+30=0
29x+30=0
Step 2: Subtract 30 from both sides.
29x+30−30=0−30
29x=−30
Step 3: Divide both sides by 29.
29x/29=-30/29

X
x = [?]
Answer:
x = 5.85
Step-by-step explanation:
Given that,
One angle = 26°
Middle angle = 90°
Third angle = 180-(90+26) = 64°
Height, H = 12
We need to find the value of x. Using trigonometry to find it such that,
[tex]\tan64=\dfrac{12}{x}\\\\x=\dfrac{12}{\tan(64)}\\\\x=5.85[/tex]
So, the value of x is equal to 5.85.
