Answer:
[tex]\mathrm{A.\: 39.3}[/tex]
Step-by-step explanation:
Let [tex]h[/tex] represent the height of the two smaller triangles in this figure. Because all three triangles are similar, we can set up the following proportion:
[tex]\frac{33}{h}=\frac{h}{y}[/tex], for [tex]y=x-33[/tex].
We can solve for [tex]h[/tex] using the Pythagorean theorem on the second largest triangle:
[tex]33^2+h^2=36^2,\\h=\sqrt{36^2-33^2},\\h=\sqrt{207}[/tex].
Now plugging in [tex]h=\sqrt{207}[/tex] into our proportion [tex]\frac{33}{h}=\frac{h}{y}[/tex], we can solve for y:[tex]\frac{33}{\sqrt{207}}=\frac{\sqrt{207}}{y}[/tex].
Cross-multiply to get:
[tex]33y=207,\\y=\frac{207}{33},\\y\approx 6.3[/tex].
Since we [tex]y=x-33, y+33=x[/tex].
Therefore, our answer is:
[tex]x=33+y=33+6.3=\fbox{$\mathrm{A.\: 39.3}$}[/tex].

Step-by-step explanation:
Anthony and Jesus decide that they want to buy a Playstation 5 together. They each have $225. Ray has a Gamestop coupon that gives him 10% off his order, so they decide to go to Gamestop. The price of the Playstation is $499.00. If tax is 7%, will they be able to buy the console? If not, how much money will they have to borrow from their parents?
Answer:
Yes, they will have enough.
Step-by-step explanation:
1. $499.00 + 7% = $533.93
2. $225 x 2 = $550
3. $550 - $533.93 = $16.07 left to spend

Suppose you anticipate needing to call the UK for a total of 250 minutes and France for 100 minutes. Will a $75 card cover the cost of this much calling? Explain your answer.
Complete question :
You have relatives living in the United Kingdom and in France. Suppose that you have purchased a prepaid phone card with a value of $75. Calls to the United Kingdom cost 23¢ per minute, while calls to France cost 21¢ per minute."Suppose you anticipate needing to call the UK for a total of 250 minutes and France for 100 minutes. Will a $75 card cover the cost of this much calling?
Answer:
cell phone card won't be enough.
Step-by-step explanation:
Cell phone card value = $75
United kingdom = 23cent per minute
France = 21 cent per minute
United Kingdom minutes = 250
France minutes = 100
Total cost :
23 cent = $0.23
21 cent = $0.21
Total :
United Kingdom = 0.23 * 250 = $57.5
France = 0.21 * 100 = $21
$21 + $57.5 = $78.5
$78.5 > $75
Then, it can be concluded that the cell phone card won't be enough.

5) In August, Yesenia was 4 feet tall. Each month since August, she has consistently grown 0.25 inc
How tall is Yesenia t months after August?
Answer:
Yesenia is 0.25t+4 inches tall after August.
Step-by-step explanation:
Given that:
Height of Yesenia in August = 4 feet tall
Growth rate since August = 0.25 inches
Number of months after August = t
According to given statement;
Height after August = Growth rate * Number of months + Height in August
Height after August = 0.25t + 4
Hence,
Yesenia is 0.25t+4 inches tall after August.
Helpppppppppppppp pleaseeeeeeeee
First, lets put this into slope intercept form
3x + 2y = -6
2y = -3x - 6
y = -3/2x - 3
The y intercept is (0, -3)
To find the x intercept we set the new equation to zero and solve
0 = -3/2x - 3
+3 +3
(2)3 = -3/2x(2)
6 = -3x
6/-3 = -3x/-3
-2 = x
The x intercept is (-2,0)
Therefore, your intercepts are:
y-int. = (0,-3)
x-int. = (-2,0)

During 24 hours a radio station spends 1/5 of the time playing rock music,2/3 playing hip hop, and the rest playing dance music.How much time is spent playing dance music?
Answer:
[tex]3.2\:\text{hours}[/tex] is spent playing dance music.
Step-by-step explanation:
Given: During [tex]24[/tex] hours a radio station spends [tex]\frac{1}{5}[/tex] of the time playing rock music, [tex]\frac{2}{3}[/tex] playing hip hop, and the rest playing dance music.
To find: How much time is spent playing dance music?
Solution:
We have,
Radio station spends [tex]\frac{1}{5}[/tex] of the time playing rock music.
Radio station spends [tex]\frac{2}{3}[/tex] of the time playing hip hop.
Radio station spends rest of the time playing dance music.
So,
Time spend on playing rock music [tex]=\frac{1}{5}\times24 = 4.8\:\text {hours}[/tex]
Time spend on playing hip hop [tex]=\frac{2}{3}\times24 = 16\:\text {hours}[/tex]
Now, total time radio station spends on all the three music is [tex]24[/tex] hours.
Therefore, rest of the time[tex]=24-(16+4.8)=3.2\:\text{hours}[/tex]
It is given that in the rest of the time, the radio station plays dance music.
Hence, [tex]3.2\:\text{hours}[/tex] is spent playing dance music.

Answer:
73°
Step-by-step explanation:
Angles on a straight line add up to 180°
angle ABC= 180-146= 34°
Angles in a traingle add up to 180°
180-34= 146°
y= 146÷2= 73°
hope it helps! please mark me brainliest
thank you! have a good day ahead
if u follow me, I will follow u back
Answer:
Option D (73°)
Step-by-step explanation:
According to Exterior Angle Property , the measure of exterior angle is the sum of the opposite interior angles.
So, according to the question -
[tex]y + y = 146[/tex]
[tex] = > 2y = 146[/tex]
[tex] = > y = \frac{146}{2} = 73[/tex]

An ice cream machine offers three flavors: vanilla, chocolate, and strawberry. Each flavor can be served as a milkshake, in a cone, or in a cup.
This is a tree diagram that represents the probability of customers choosing the different ice cream options.
What is the value of Z?
Group of answer choices
0.2
0.4
0.35
0.45
The value of z = 0.2
What is probability?"Probability is a branch of mathematics which deals with finding out the likelihood of the occurrence of an event."
Sum of probabilities:"The sum of the probabilities of all outcomes must equal 1."
For given situation,
An ice cream machine offers three flavors: vanilla, chocolate, and strawberry. Each flavor can be served as a milkshake, in a cone, or in a cup.
The probability of customers choosing Vanilla flavor = 0.45
The probability of customers choosing Chocolate flavor = 0.35
We need to find the probability of customers choosing Strawberry flavor i.e., to find the value of z.
The sum of the probabilities of all outcomes must equal 1.
From given tree diagram,
⇒ 0.45 + 0.35 + z = 1
⇒ 0.8 + z = 1
⇒ z = 1 - 0.8
⇒ z = 0.2
Therefore, the correct answer is option (A)

Answer:
B) 3 1/3
Step-by-step explanation:
To divide the fractions, simply follow these steps.
First, flip the second fraction, so that the numerator is the denominator, and the denominator is the numerator. Change the division sign into a multiplication:
(2/3)/(1/5) = (2/3) * (5/1)
Next, multiply straight across:
(2/3) * (5/1) = (2 * 5)/(3 * 1) = 10/3
Finally, simplify. Change the improper fraction into a mixed:
10/3 = 3/3 + 3/3 + 3/3 + 1/3 = 3 1/3
B) 3 1/3 is your answer.

Answer:
I got 3 1/3

[tex]f(x) = - 5 {x}^{2} + 10x + 8[/tex]
[tex]0 = - 5 {x}^{2} + 10x + 8[/tex]
[tex] - 5 {x}^{2} + 10x + 8 = 0[/tex]
[tex]delta = {10}^{2} - 4( - 5)(8)[/tex]
[tex]delta = 100 + 160[/tex]
[tex]delta = 260[/tex]
[tex]x = \frac{ - (10) + \sqrt{delta} }{2 \times ( - 5)} \\ [/tex]
[tex]x = \frac{ - 10 + \sqrt{260} }{ - 10} \\ [/tex]
[tex]x = \frac{ - 10 + 2 \sqrt{65} }{ - 10} \\ [/tex]
[tex]x = \frac{ - 5 + \sqrt{65} }{ - 5} \\ [/tex]
And
[tex]x = \frac{ - 10 - \sqrt{delta} }{ - 10} \\ [/tex]
[tex]x = \frac{ - 10 - 2 \sqrt{65} }{ - 10} \\ [/tex]
[tex]x = \frac{ 5 + \sqrt{65} }{5} \\ [/tex]
