A cylinder has a volume of 200 cm³. If the height of the cylinder is 10 cm, what is the radius of the cylinder
Answer:
2.5
Step-by-step explanation:
The radius of a cylinder formula is
R = √(V / π × h)Plug in
R = √(200 / 3.14 × 10)So . .
R = √(6.4)R = 2.5

At a hockey game a vender sold a combined total of 105 sodas and hot dogs. The number of sodas sold was 39 more than the number of hot dogs sold find the number of soda sold and the number is hot dog sold
Answer:
Hot dog sold = 33
Sodas Sold = 72
Step-by-step explanation:
Given:
At a hockey game a vender sold a combined total of 105 sodas and hot dogs. The number of sodas sold was 39 more than the number of hot dogs sold
To Find:
Number of soda/hot dog sold
Solve:
h + ( 39 + h ) = 105
h + 39 + h = 105
2h + 39 = 105
h + 19.5 = 52.5
h = 52.5 - 19.5
This as a system does not use any inequality. "39 more than" means, +39.
h = 33 meaning d= 72
Add to check Answer:
33 + 72 = 105
Thus,
Hot dog sold = 33
Sodas Sold = 72

Which figures demonstrate a single translation?
Select each correct answer.
Translation of a figure is the situation when a figure is moves from one place to another place. The size of the figure does not changes in translation. The figure does not rotate in the translation. As the option 3 (below the first option) and 4 demonstrate the single translation hence, option 3 and 4 is the correct option.
Given-Given option shows the different translation and rotation of the original figure. It has to be known about the translation before checking the correct option.
What is translation?Translation of a figure is the situation when a figure is moves from one place to another place. The size of the figure does not changes in translation. The figure does not rotate in the translation.
In option 1 the object flips to the opposite side of the figure figure. Thus the option 1 does not demonstrate the single translation.In option 2 (right to the first option) the figure flips to the opposite side of the original figure and then translate to other location. Thus the option 2 does not demonstrate the single translation.In option 3 (below the first option) the figure moves to southeast direction to its position. Thus the option 4 demonstrate the single translation. Therefore option 4 is the correct option.In option 4 the figure moves to right from its location. Thus the option 3 demonstrate the single translation. Therefore option 3 is the correct option.As the option 3 (below the first option) and 4 demonstrate the single translation hence, option 3 and 4 is the correct option.

Since the variable x is the numerator of the fraction, we first need to multiply each side by 6, since the denominator is 6. After doing this, the equation should now look like this: [tex]18 = x + 31[/tex]. Next, we subtract 31 from 18 following the rule. 18 - 31 = -13. x is equal to -13.
For shown work in order:
[tex](6) 3 = x +31[/tex]
[tex]18 = x + 31[/tex]
[tex]18 - 31 = x[/tex]

USING Pythagoras theorem find the formula of equilateral triangle.
Answer:
Answer with explanation is below~
Step-by-step explanation:
We could easily obtain the formulae/formula of an equilateral triangle not only through Pythagoras Theorem, but also through Heron's formula.
INTRODUCTION:
What's equilateral triangle?
It's an triangle, whose all sides're of equal measurement.What's Heron Formula?
It's just a formula actually,take an example:Let,a,b and c denotes the lengths of 3 sides of any triangle,then the area will be given as:[tex] \boxed{\rm \: Area= \sqrt{s(s - a)(s - b)(s - c)} \: units ^{2}} [/tex]
Where,
s = (a+b+c)/2 {Half of the perimeter, basically}What's Pythagoras' Theorem?
It's actually like a formula but a theorem introduced by Pythagoras.SOLVING:
Let,ABC an equilateral triangle of sides a.
Now:Draw a perpendicular straight line AM to the side BC(Name each part of triangle)
So it's clear that ∆AMB is a right angled triangle at M, BM = (1/2)BC = a/2.
Please note AM here represents the height of ∆ ABC.
Let's use Pythagoras' theorem now.[tex] \boxed{\rm \: AM = \sqrt{AB^2-BM^2}}[/tex]
AB = aBM = a/2[tex] \rm \: AM = \sqrt{a {}^{2} - { \bigg( \cfrac{a}{2} \bigg) }^{2} } [/tex]
[tex] \rm \: AM = 3 \: \cfrac{a {}^{2} }{4} [/tex]
[tex] \rm \: AM = \cfrac{ \sqrt{3} }{2} \: a[/tex]
Now find the area of ∆ABC:
[tex] \rm \triangle \: ABC = \cfrac{1}{2} \times \: BC \times A [/tex]
[tex] \rm \: \triangle \: ABC = \cfrac{1}{2} \times a \times \cfrac{ \sqrt{3}}{4}a [/tex]
[tex] \boxed{\rm\triangle \: ABC = \cfrac{ \sqrt{3 } }{4} a {}^{2} \: units {}^{2}} [/tex]
Hence,the formulae of equilateral triangle using Pythagoras' theorem is {√(3)/4} a^2
[tex] \rule{225pt}{2pt}[/tex]
Extras:
Now let's find the area using Heron's Formula.
Solving:
Let each side of an equilateral triangle be a.
SO, then:
s = (3a/2)
We know that, (Heron's formula)
[tex] \rm \: A = \sqrt{s(s - a)(s - b)(s - c)} [/tex]
Now the area A :
[tex]\rm AR(A)= \sqrt{ \cfrac{ 3a } 2 \bigg(\cfrac{ 3a }{2} - a \bigg)\bigg(\cfrac{ 3a }{2} - a \bigg)\bigg(\cfrac{ 3a }{2} - a \bigg)} [/tex]
[tex]\rm AR(A)= \sqrt{ \cfrac{3a}{2} \bigg( \cfrac{a}{2} \bigg)\bigg( \cfrac{a}{2} \bigg)\bigg( \cfrac{a}{2} \bigg)}[/tex]
[tex]\rm \boxed{ \rm AR(A)= \cfrac{ \sqrt{ 3a}}{4} \: a {}^{2} \: \: units {}^{2}} [/tex]
And voila! we're done!
I hope this helps! :)

Triangle A B C is shown. Angle B C A is a right angle. The length of hypotenuse A B is 26, the length of A C is 10, and the length of B C is 24.
Given right triangle ABC, what is the value of tan(A)?
Answer:
tan(A) = 12/5Step-by-step explanation:
Given a right angle triangle ABC.
If ∠BCA = 90°
the hypotenuse AB = 26
AC = 10 and BC = 24.
Using the SOH, CAH, TOA trigonometry identity, SInce we are to find tanA, we will use TOA. According to TOA;
Tan (A) = opp/adj
Taken BC as opposite side since it is facing angle A directly and AC as the adjacent;
tan(A) = BC/AC
tan(A) = 24/10
tan(A) = 12/5
Answer:
[tex]\ tan \ A = \dfrac{24}{10}[/tex]
Step-by-step explanation:
[tex]\sf Tan \ A = \dfrac{opposite \ side \ of \ angle \ A}{adjacent \ side \ of \ angle A}\\\\Tan \ A = \dfrac{BC}{AC}\\\\Tan \ A = \dfrac{24}{10}[/tex]
A snail crawls 83 cm due west and then
78 cm due north.
Work out the bearing of the snail from its
starting point.
Give your answer to the nearest degree.
Answer:
313°
Step-by-step explanation:
The reference angle (α) can be found using the tangent relation:
Tan = Opposite/Adjacent
__
In this problem, that means ...
tan(α) = 78/83
α = arctan(78/83) ≈ 43° . . . . . . angle from -x axis
The bearing angle will be this value added to 270°, since bearing angles are measured clockwise from north.
bearing = 270° +43° = 313°

C. look at the genre
The similarities and differences in a non-fiction text look at how the subject or events are portrayed.
What is a non-fiction text?Comparing non-fiction texts can focus on the similarities between the texts - things they have in common. You can also contrast texts and focus on their differences - things that set the texts apart from each other. You could compare and contrast the following:
Form – What types of text (letter, news report, etc) are they?
Purpose – What job (persuading, informing, advertising) is each text doing?
Audience – Who is the intended reader of the text?
Subject matter – What are the texts about?
Language choices – What kinds of words, images or rhetorical devices are being used?
Structure – How is the text ordered?
Tone – What is the overall tone or mood of the writing?
Non-fiction texts are all around us, and comparing them can help you become more aware of how language is being used in society. Comparing non-fiction texts can often prompt you to notice things that you might not have considered about a text in isolation.

[tex]y = a*x^2 + b*x + c[/tex]
The y-intercept is the point (0, c), and the sign of the coefficient a determines if it opens up or down.
If a > 0, then it opens up.If a < 0, then it opens down.In this case, the quadratic equation is:
[tex]y = -2x^2 + 4[/tex]

Answer:
h = 3V/(πr²)
Step-by-step explanation:
The formula can be solved for h by multiplying both sides by the inverse of the coefficient of h.
_____
Additional comment
Whenever a variable has a coefficient you don't want, you can make that be 1 by multiplying the equation by the inverse of the coefficient. This is the same as dividing by the coefficient. This makes use of the fact that for any non-zero 'a', the ratio a/a has a value of 1. Anything multiplied by 1 is unchanged.
V = ah ⇒ V/a = (ah)/a = h(a/a) = h·1 = h
Note that we multiply the whole equation (both sides of the equal sign) by 1/a. The basic rule of equality is that you can do whatever you like to an equation, as long as you do it to both sides.
