well, we know the aquarium is 23 bucks, the total is 23.23 or namely the tax is 0.23.
if we take 23 to be the 100%, whas is 0.23 off of it in percentage?
[tex]\begin{array}{ccll} amount&\%\\ \cline{1-2} 23&100\\ 0.23&x \end{array}\implies \cfrac{23}{0.23}=\cfrac{100}{x}\implies 23x=23\implies x=\cfrac{23}{23}\implies x=\stackrel{\%}{1}[/tex]

mZQPS = 88
mZRPS = 5x + 34°
mZQPR = 8x + 15 °
Find mZRPS:
Answer:
49
Step-by-step explanation:
First, you need to solve for x.
88 = 5x + 34 + 8x 15
88 = 13x + 49
88 - 49 = 13x
39 = 13x
39/13 = x
3 = x
Now substitute 3 in place of x to find rps
rps = 5x+34
rps = 5*3 + 34
rps = 15 + 34
rps = 49

Use substitution to compose y=6u^2 and u=5x−1. Enter your answer as an equation, and simplify your answer as much as possible.
Answer:
y = 150x^2 -60x +6
Step-by-step explanation:
Do what the problem statement tells you: substitute for u.
y = 6u^2
y = 6(5x -1)^2 . . . . . . . . . . substitute 5x-1 for u
y = 6(25x^2 -10x +1) . . . . expand the square
y = 150x^2 -60x +6 . . . use the distributive property
Which expression is equivalent to (StartFraction 4 Superscript five-fourths Baseline time 4 Superscript one-fourth Baseline Over 4 Superscript one-half baseline EndFraction) Superscript one-half?.
The expression is equivalent to 4 Superscript five-fourths Baseline time 4 Superscript one-fourth Baseline Over 4 Superscript one-half baseline is,
[tex]x=2[/tex]
What is equivalent expression?Equivalent expression are the expression whose result is equal to the original expression, but the way of representation is different.
Given information-
The expression given in the problem is,
[tex]\left((4^{\dfrac{5}{4}}\times4^{\dfrac{1}{4}}\div 4^{\dfrac{1}{2}} \right)^{\frac{1}{2}}[/tex]
Let the result of the given expression is x. Rewrite the given expression as,
[tex]x=\left(\dfrac{4^{\dfrac{5}{4}}\times4^{\dfrac{1}{4}}}{4^{\dfrac{1}{2}}} \right)^{\frac{1}{2}}[/tex]
When the two number is multiplies with the same base, the powers of the number is added in result. Thus,
[tex]x=\left(\dfrac{4^{(\dfrac{5}{4}+\dfrac{1}{4})}}{4^{\dfrac{1}{2}}} \right)^{\frac{1}{2}}\\x=\left(\dfrac{4^{(\dfrac{3}{2})}}{4^{\dfrac{1}{2}}} \right)^{\frac{1}{2}}[/tex]
When the two number is divided with the same base, the powers of the number is subtracted in result. Thus,
[tex]x=\left(4^{\dfrac{3}{2}-\dfrac{1}{2}} \right)^{\frac{1}{2}}[/tex]
[tex]x=\left(4^1} \right)^{\frac{1}{2}}\\x=\left(4} \right)^{\frac{1}{2}}\\x=(2^2)^{\dfrac{1}{2}} \\x=2[/tex]
Thus the expression is equivalent to 4 Superscript five-fourths Baseline time 4 Superscript one-fourth Baseline Over 4 Superscript one-half baseline is,

Answer: z = [tex]\sqrt{10}[/tex]
Step-by-step explanation:
To find z, you must set up a proportion to solve.
To find the altitude of a special right triangle, the formula is:
[tex]\frac{a}{x} =\frac{x}{b}[/tex]
You can use 5 as a and 2 as b to complete the proportion:
[tex]\frac{5}{z} =\frac{z}{2}[/tex]
Next, to solve:
Step 1: Cross-multiply.
[tex]\frac{5}{z} =\frac{z}{2}[/tex]
(5)*(2) = z*z
10 = z²
Step 2: Take square root.
10 = z²
√10 = z

solve for x. Round to the nearest tenth,if necessary
Answer:
x = 83.7 units
Step-by-step explanation:
given adjacent: 56, given angle: 48°, asked to find hypotenuse, x?Using cosine rule:
→ adjacent/hypotenuse = cos(∅)
→ 56/hypotenuse = cos(48)
→ hypotenuse = 56/cos(48)
→ hypotenuse = 83.7 units
Answer:
83.7
Step-by-step explanation:
We can solve this using SOHCAHTOA:
RQ is adjacent to angle Q and x is the hypotenuse, so we must use the cosine function.
[tex]cosQ = \frac{RQ}{SQ}\\ cos(48) = \frac{56}{x}\\ x = \frac{56}{cos(48)}\\ x = 83.7[/tex]

The probability of winning a certain game is 0.5. If at least 70 percent of the games in a series of games are won, the player wins a prize. If the possible choices for n are n
The equation that allows determining the probability that the player wins the prize after n games is [tex]0.35^n[/tex] = Probability. The player should choose n = 10.
The simple definition of probability is the likelihood that an individual event will occur. It can be discussed the probabilities of distant outcomes, or how probable they are, whenever we're skeptical of how an occurrence will turn out. Statistics refers to the study of events subject to probability.
First, solve the following equation to find the likelihood of the player winning the prize after n games given that the probability of winning a specific game is 0.5 and that the player wins a prize if at least 70[tex]\%[/tex] of the games in a series are won.
[tex]Probability = 0.5^n \times 0.70[/tex]
[tex]Probability = 0.35^n[/tex]
It is evident here that the larger the value of n, the lesser the chances to win.
For example, if there were five games played, the equation would be as follows:
[tex]0.35^5 = 0.005[/tex]
So. the value of n chosen by the player should be 10.

Which is the graph of y=3/4x-3?
Answer:
Graph A
Step-by-step explanation:
The y-intercept is -3, which is the y-value when the graph hits the y-axis.
Graph A and B both hit the y-intercept of -3.
The slope is 3/4, which means the line rises 3 units as it runs 4.
This time, only Graph A has the correct slope.
The correct answer is [tex]\boxed{\text{Graph A}}[/tex]
-Chetan K
Answer:
Graph A
Step-by-step explanation:
The formula is in the form y=mx+c, where m is the gradient and m is the y-intercept, this means that the y-intercept is (0,-3) which rules out Graph B.
To find the gradient we use [tex]\frac{rise}{run}[/tex], this means that the vertical value has to be 3 and the horizontal distance 4 and this rules out Graph C as its gradient is 3/2. That means that graph A matches the equation the best.

Answer:
See, that doesn't make sense.
First of all, 4 is the only number equal to 4. Sp, it'd be 9+4 = 13

find the unknown sizes of an angles of the following polygons.
Answer:
A is an irregular pentagon - total angle is 540. So x is 100
(540 - 440=100)
B. 3a + 345 = 540
- 345 both sides
3a=195
÷3
a = 65
2a = 130 (65x2)
C. X = 120 (angles on straight lines adds to 180)
3y + 300 = 540
- 300
3y = 240

Y= 80
