I am just confused on how to do this question. A 37-inch TV is 37-inches diagonally across the screen. Which of these dimensions best describes a 37-inch TV? A. 15 x 34 B. 16.5 x 32 C. 17 x 28 D. 17 x 32
Answers
Given that,
A TV is 27 inch diagonally across the screen.
To find,
The dimensions that best describes a 37 inch TV.
Solution,
Let a and b are length and width of the TV. Let c be the diagonal. Using Pythagoras theorem,
[tex]c=\sqrt{a^2+b^2}[/tex]
If dimensions are 15 x 34,
[tex]c=\sqrt{15^{2}+34^{2}}\\\\=37.16\ inch[/tex]
If dimensions are 16.5 x 32,
[tex]c=\sqrt{16.5^{2}+32^{2}}\\\\=36.003\ inch[/tex]
If dimensions are 17 x 28,
[tex]c=\sqrt{17^{2}+28^{2}}\\\\=32.756\ inch[/tex]
If dimensions are 17 x 32,
[tex]c=\sqrt{17^{2}+32^{2}}\\\\=36.23\ inch[/tex]
It is clear that if dimensions are 15 x 34, the diagonal is 37 inches. Hence, the correct option is (a).

Answer:
θ = 85.93° (≈ 86°)
Step-by-step explanation:
arc length : 2πr = θ : 360°
7.5 : 2πr = θ : 360°
θ = (7.5 * 360°) / (2π*5) = 2700 / 31.42 = 85.93°
θ ≈ 86°

Stacy is measuring milk to make pancake batter. The recipe calls for \dfrac{3}{4} 4 3 start fraction, 3, divided by, 4, end fraction of a jug of milk. She has \dfrac{1}{4} 4 1 start fraction, 1, divided by, 4, end fraction of a jug now. How much more milk does she need?
Answers
Answer:
1/2 cup of milk
Step-by-step explanation:
Given
Total cup of milk needed = 3/4 cup of milk
Amount she has = 1/4 cup of milk
The amount of milk she needed = Total - Amount she has
Amount she needed = 3/4 - 1/4
Amount she needed = (3-1)/4
Amount she needed = 2/4
Amount she needed = 1/2
Hence she needs 1/2 cup of milk more
Show that the equation x^3+4x=6 has a solution between 1.1 and 1.2
plz I need help my dudes I have no clue what I’m doing
Answers
Answer:
see explanation
Step-by-step explanation:
If there is a solution between x = 1.1 and x = 1.2 then there will be a change in sign when the equation is evaluated at the points, indicating the graph has crossed the x- axis, where the solution lies.
Given
x³ + 4x = 6 ( subtract 6 from both sides )
x³ + 4x - 6 = 0 ← in standard form
Evaluating for x = 1.1
(1.1)³ + 4(1.1) - 6
= 1.331 + 4.4 - 6 = - 0.269 ← < 0
Evaluating for x = 1.2
(1.2)³ + 4(1.2) - 6
= 1.728 + 4.8 - 6 = 0.528 ← > 0
Since there is a change in sign the graph has crossed the x-axis from below / indicating a solution between x = 1.1 and x = 1.2

A letter is chosen at random from the letters of the word ASSASSINATION, then the probability that the letter chosen is a vowel is in the form of 6/2x+1, then find x.
Answers
Step-by-step explanation:
In the word "Assassination",
there are 13 letters in total and 6 vowels.
Probability of picking a vowel = 6/13.
Since 6/(2x + 1) = 6/13, 2x + 1 = 13, x = 6.
Nancy wrote the expression 3x-12 to represent the relationship in the table of values.use operations to write two equivalent expressions.
Answers
Answer:
Please check the explanation.
Step-by-step explanation:
Given the expression
3x-12
1)
Writing the expression in an equivalent form
3x-12
Factor out common term 3
3x-12 = 3(x-4)
Thus, 3(x-4) is equivalent to 3x-12.
2)
Writing the expression in an equivalent form
3x-12
Multiply the expression by 2/2
[tex]3x-12\:=\frac{2}{2}\:\times \:\left[3x-12\right][/tex]
Therefore, [tex]\frac{2}{2}\:\times \:\left[3x-12\right][/tex] is equivalent to 3x-12.
if you have 3 cups of glue u use 2/3 cup of glue how much slime can u make?
Answers
I did 3/1 times 2/3 which would equal to 2
So in the numerator 3 times 2 equals 6 and in the denominator 1 times 3 equals to 3 which you’ll know have 6/3. so now you divide both of them by three since you can simplify it and it would left as 2.
Therefore you can make 2 slimes.
If a factory can produce 250 desks in 5 days, how many desks will it produce in 15 days?
Answers
Answer:
750 would be ur answer
Step-by-step explanation:
happy new year!
Answer:750 desks
Step-by-step explanation: I would start by setting up an equation. 5d=250 (d means days). Then, to isolate the d, I would divide both sides of the equation by 5. I would get d=50. So there are 50 desks made daily. To find out the number of desks made in 15 days, I would just multiply both sides of the equation d=50 by 15 and I would get 15d=750. That means, there are 750 desks produced in 15 days. I hope this helps you out a bit!

Answers
Step-by-step explanation:
Just substitute the values of a and b
2a^2 + 3b^3 - 10
2x2^2 + 3 x (-2)^3 - 10
= 2 x 4 + 3 x (-8) - 10
= 8 - 24 - 10
= 8 - 34
= -26
Answer:
- 26
Step-by-step explanation:
Given
2a² + 3b³ - 10 ← substitute a = 2, b = - 2 into the expression
= 2(2)² + 3(- 2)³ - 10
= 2(4) + 3(- 8) - 10
= 8 - 24 - 10
= - 16 - 10
= - 26
