Answer:
45.
Divide 48 by 100 (48/100*)
Then, multiply by the given percentage, 5.8%
→ The formula to find percentage is to divide the found number by 100 and then multiply by the closest given number.
Therefore,the [tex]2.61[/tex] is the [tex]5.8[/tex] % of the number [tex]45.[/tex]
What is the percentage?
A percentage is a number or ratio expressed as a fraction of [tex]100[/tex]. It is often denoted using the percent sign, "%".
As per the given information
Let the number is [tex]x[/tex].
[tex]\frac{2.61}{x}=\frac{5.8}{100}\\\\\\2.61(100)=5.8(x)\\\\\\261=5.8x\\\\\\x=\frac{261}{5.8}\\\\\\x=45[/tex]
Hence, the [tex]2.61[/tex] is the [tex]5.8[/tex] % of the number [tex]45.[/tex]

Elaine is in London for one day only. She only has time to see two shows of the three shows she likes. The shows are Hamilton, Aladdin and Thriller. She makes her choice of the two shows at random. What is the probability that she sees Aladdin and Thriller?
Answer:
[tex]\frac 13[/tex]
Step-by-step explanation:
All three shows she likes are Hamilton, Aladdin, and Thriller.
But she can watch only two shows among the three shown.
The possible combination of the shows she can watch are
(Hamilton and Aladdin), (Aladdin and Thriller) and (Hamilton and Thriller).
So, the total number of possible events (available options)= 3.
As we have to determine the probability of watching Aladdin and Thriller, so here Aladdin and Thriller is the favorable event.
So, the number of favorable event=1
Now,
[tex]\text{Probability}=\frac{\text{Total number of possible events}}{\text{Total number of favorable events}}[/tex]
[tex]=\frac{1}{3}[/tex]
Hence, the probability that she sees Aladdin and Thriller is [tex]\frac 1 3[/tex].

Answer:
Factored form: (x+4)(x+5) = 0
x = -5 or -4
Step-by-step explanation:
To factor x^2 + 9x + 20, we need to find 2 numbers that multiply to 20 and add up to 9.
The reason for that is because when you multiply (x+a)(x+b) using FOIL, you will get x^2 + ax + bx + ab.
Anyway, 4 and 5 would satisfy this, because 4+5 = 9 and 4*5 = 20. We can then factor the equation to (x+4)(x+5).
To solve (x+4)(x+5) = 0, we need to make either x+4 = 0 or x+5 = 0. That means x can be either -5 or -4.

Answer:
x = 145 degrees
Step-by-step explanation:
In leftmost triangle, missing angle :
= 180 - (90 + 35)
= 55 degrees
Top angle of middle triangle :
= 180 - (60 + 55)
= 180 - 115
= 65 degrees
Bottom angle of middle triangle :
= 180 - (90 + 65)
= 25 degrees
Linear pair
= 180 - 25
=> x = 145 degrees

The of the object = 180°
Therefore, a line drawn though the a point on the preimage passing through the center of rotation
A second line is drawn from the center of rotation, towards the direction of the expected location of the image of the chosen point on the preimage which should in this case be 180° and the distance from the location of the point on the image to the given center of rotation should be the same as the distance of the point of the preimage from the given center of rotation.

How can you know if this equation is true? 12+38=410=25 1 2 + 3 8 = 4 10 = 2 5 CLEAR CHECK Because 1+3=4 1 + 3 = 4 and 2+8=10 2 + 8 = 10 , this equation must be true. Because 25<12 2 5 < 1 2 , this equation can not be true. This equation must be true, because when you add fractions the sum is always less than 12 1 2 . Because 38<12 3 8 < 1 2 , this equation must be true.
Given:
The equation is
[tex]\dfrac{1}{2}+\dfrac{3}{8}=\dfrac{4}{10}=\dfrac{2}{5}[/tex]
To find:
Whether the given equation is true or not.
Solution:
In addition of two fractions, we can not add numerator and denominator separately. First we need a common denominator, then we add numerators.
We have,
[tex]\dfrac{1}{2}+\dfrac{3}{8}[/tex]
Taking LCM, we get
[tex]\dfrac{1}{2}+\dfrac{3}{8}=\dfrac{1\times 4+3}{8}[/tex]
[tex]\dfrac{1}{2}+\dfrac{3}{8}=\dfrac{4+3}{8}[/tex]
[tex]\dfrac{1}{2}+\dfrac{3}{8}=\dfrac{7}{8}\neq \dfrac{4}{10}[/tex]
So, the given equation is not true.
Therefore, the correct option is B.
If a function is defined by the equation y=12x−32, which equation defines the inverse of this function?
A. y=2x+3
B. y=2x+32
C. y=2x−3
D. y=2x−32
Answer:
A. Y=2x+3
Step-by-step explanation:
because im right
If a function is defined by the equation y = 2x−32, the equation that defines the inverse of this function would be: B. y=2x+32
How to determine the inverseTo determine the inverse of the function, we would first replace x with y in the function:
y = 2x - 32
x = 2y - 32
x + 32 = 2y
Divide both sides by 2
x/2 + 32/2 = y
f−1(x) = x/2 + 32/2
The common facot between the denominatoes of the values is 2. So, when expanded, we have;
(x + 32)/2
So, the closest option that represents the inverse is B. y=2x+32.
