Answer:
[tex]y=\frac{9\sqrt{3} }{2}[/tex] or 7.79 x= 9/2 or 4.5
explanation:
This is a special right triangle; a 90-60-30 triangle.
The side labelled y = a, side labelled x is equal to [tex]a\sqrt{3}[/tex], and the hypotenuse equals 2a.
First solve for a. [tex]9\sqrt{3}=2a[/tex] [tex]a=\frac{9\sqrt{3} }{2} =y[/tex] and that gives you y.
Then use a to find x. [tex]a\sqrt{3} =x[/tex] so [tex]\frac{9\sqrt{3} }{2} *\sqrt{3} = 9/2=4.5[/tex]

What is the radius of the circle shown, given that point P is its center?
A)13.5 ft
B)27 ft
C)54.5 ft
D)729 ft. PLSSS HELP ASAP
Answers
The radius of the circle with point P as its center is 13.5 ft.
A circle is the locus of a point such that its distance from a fixed point is always constant (the same).
The diameter of a circle is a straight line segment that passes through the center of the circle and has endpoints on the circle.
The radius of a circle is half the diameter of the circle.
Given that the diameter of the circle is 27 ft. hence, the radius of the circle is:
Radius = Diameter / 2
Radius = 27 ft / 2 = 13.5 ft.
Hence the radius of the circle is 13.5 ft.

Explanation: 2^3+(2-10)-42
first you’re going to evaluate the exponent( or in other words simplify) which will give you :
8 + ( 2-10 ) - 42
then subtract which will give you :
8 + (-8) - 42
then Add
8 - 8 -42
and then find the total :

A store marks its merchandise up 225% from the price it pays. The store buys a bag of chips for $1.20. How much will the store charge for the bag of chips? (PLS give an explanation too!!)
Answers
Answer:
$3.90
Step-by-step explanation:
multiply 1.20 x 2.25 and add the answer to 1.20
They would have to add that change up to cents because the store marks up to 225% from the prince it’s pays and we only add the 25 because if we add the 225 that changes the dollar that’s suppose to stay as 1$.
20+25=46 cents. U know it’s equals 45 cents because it’s just like counting by fives.

There is A Spinner That Have 8 Space 1-8 What Is The Probability That Te Spinner Will NOT Land On 5 or 8?
Answers
Answer:
[tex]\frac{3}{4}[/tex]
Step-by-step explanation:
Key skills needed: Probability, Possible Outcomes
1) We are given a spinner --> With numbers: 1,2,3,4,5,6,7, and 8
That means there are 8 numbers on the spinner.
2) The problem asks what is the probability that the spinner will not land on 5 or the 8.
To calculate this --> [tex]\frac{acceptedoutcomes}{total}[/tex]
3) The accepted outcomes are when the spinner lands on --> 1,2,3,4,6,7
That is 6 accepted outcomes.
4) The total outcomes is 8 (since there are numbers the spinner can land on).
5) Therefore, the answer would be [tex]\frac{6}{8}[/tex]
[tex]\frac{6}{8}[/tex] can be simplified into [tex]\frac{3}{4}[/tex] as both the numerator (6) and the denominator (8) share a factor of 2.
6) With this --> [tex]\frac{3}{4}[/tex] is the answer.
If the length of a rectangle is given the expression 2 square root of 153 and the width is given by 4 square root of 68, which radical expression represents the perimeter of the rectangle
Answers
C) 28√17
Step-by-step explanation:
The perimeter is twice the sum of the two given side lengths, so is ...
P = 2(L +W) = 2(2√153 +4√68)
= 2(6√17 +8√17) = 2(14√17)
P = 28√17 . . . . . matches choice C
_____
This is about simplifying radicals. The applicable rules are ...
√(ab) = (√a)(√b)
√(a²) = |a|
__
153 = 9×17, so √153 = (√9)(√17) = 3√17
68 = 4×17, so √68 = (√4)(√17) = 2√17
_____
Comment on the problem presentation
It would help if there were actually radicals in the radical expressions. We had to guess based on the spacing and the answer choices.
In any event, this problem can be worked with a calculator. Find the perimeter (≈115.45) and see which answer matches that. (That's what I did in order to verify my understanding of what the radical expressions were.)
The circumference of this tabletop is 24π inches, Which of the following best describes how to determine the area of the tabletop?
A) Multiply 2(24) to calculate the diameter. Then multiply the diameter by π
B Find half of 24 to calculate the radius. Then multiply the radius by π.
C Multiply 2(24) to calculate the diameter. Then square the diameter and multiply the result by it π
D Find half of 24 to calculate the radius. Then square the radius and multiply the result by π.
Answers
Answer:
D Find half of 24 to calculate the radius. Then square the radius and multiply the result by π.
Step-by-step explanation:
Given that circumference of circle is: [tex]24 \pi[/tex]
The formula for circumference of circle is:
[tex]C = 2\pi r[/tex]
Comparing both formulas, we get
[tex]24\pi = 2\pi r\\24 = 2r\\r = \frac{24}{2}\\r = 12[/tex]
The radius is obtained by dividing 24 by 2.
We also know that the area of circle is:
[tex]A = \pi r^2[/tex]
The radius is being squared and then multiplied by pi to get the area.
Hence,
The correct answer is:
D Find half of 24 to calculate the radius. Then square the radius and multiply the result by π.
