A 60-inch flat screen gets its name from the Pythagorean Theorem. The "60" represents the diagonal of the
screen. If the base of the TV is 48 inches, find the height.
Select the correct response:
36 inches
072 inches
54 inches
24 inches
Answer:
A- 36 inches
Step-by-step explanation:
The equation gives you 60 as a diagonal, so that means that 60 is the hypotenuse. It also gives you 48 as the length of a base.
Putting that into the Pythagorean theorem, you get...
48^2 + ?^2 = 60^2
Now, you need to solve for ?. After solving through the equation and simplifying, you're gonna get 36.

find the measures of the numbered angles in rhombus DEFG
Answer:
∠1 = 36°
∠2 = 72°
∠3 = 72°
∠4 = 72°
∠5 = 36°
Step-by-step explanation:
The angles of rhombus are ∠1 = 36°, ∠2 = 72°, ∠3 = 72°, ∠4 = 72°, ∠5 = 36°.
What is a rhombus?
A rhombus is a quadrilateral with four equal sides and opposite equal angles. It has two diagonals that bisect each other at right angles. It also has opposite sides parallel and the sum of all the four interior angles is 360 degrees.
For the given situation,
From the diagram of rhombus,
The angle is 72°.
In rhombus,
Opposite angles are equal.
So, [tex]\angle2 = \angle3 = \angle4[/tex] are equal to [tex]\angle72[/tex].
Diagonals bisect the angles and the sum of two adjacent angles is equal to 180 degrees.
⇒ [tex]\angle D + \angle E = 180[/tex]
Here, [tex]\angle D = \angle 72 + \angle 72[/tex]
⇒ [tex]\angle D = \angle 144[/tex]
Thus, [tex]\angle E = \angle 180 -\angle 144[/tex]
⇒ [tex]\angle 1 = \angle 36[/tex]
we know that, [tex]\angle E = \angle G[/tex]
⇒ [tex]\angle 5 = \angle 36[/tex]
Hence we can conclude that the angles of rhombus are ∠1 = 36°, ∠2 = 72°, ∠3 = 72°, ∠4 = 72°, ∠5 = 36°.

select the statement that does not correctly use probability to describe an event
Answer:
D
Step-by-step explanation:
Probability is, by definition, a number between 0 and 1, which can be expressed as a fraction or a percentage. For example, the odds of getting heads if you throw a fair coin are 50%, or ½. The odds of not getting heads are 1-½=½.
If the probability of something happening is 1, it means that that thing will happen for sure. Likewise, if the probability of an event is 0, it means that the event will never happen.
You can therefore easily understand that it doesn't make sense to have a probability greater than 1, as we have in choice D.

Write a function rule for the values in the table
10
10
12
20
18
50
20
60
y=
Answer:
y = 5x - 40
Step-by-step explanation:
The function rule can be written in slope-intercept form, y = mx + b.
Let's find slope (m) and y-intercept (b) of the function, using the values given in the table.
✔️Slope (m) = change in y / change in x
Using two pair of values from the table, (10, 10) and (12, 20),
Slope (m) = (20 - 10) / (12 - 10) = 10/2 = 5
Slope (m) = 5
✔️ y-intercept (b):
Substitute (x, y) = (10, 10) and m = 5 into y = mx + b.
Thus:
10 = 5(10) + b
10 = 50 + b
10 - 50 = b
b = -40
✔️Write the function by substituting m = 5 and b = -40 into y = mx + b
Thus:
y = 5x + (-40)
y = 5x - 40
In the figure shown, GD = 3x + 5, GF = 6x-4, and G is the incenter of AABC. Find GE
Answer:
GE = 14
Step-by-step explanation:
The incenter is equidistant from the sides, so GD = GE = GF.
Set the expressions for GD and GF equal to each other and solve for x.
3x + 5 = 6x - 4
5 = 3x - 4
9 = 3x
3 = x
Now plug this value into either expression, say for GD. GD = 3(3) + 5 = 14.
GE must be the same, GE = 14

The radius of a circle is 17 in. Find its area in terms of π.
A≈907.92in²
Because:
A=πr2=π·172≈907.92028in²
Answer:
289π or 907.46 in
Step-by-step explanation:
The formula for area of a circle is π r².
The radius is 17, so the first step is 17².
17²= 289
Next, you multiply 289 by pi (3.14).
3.14 x 289 = 907.46.
Therefore, the area in terms of pi is 289π or 907.46 in.
Prove that \displaystyle \frac{\cos \theta}{1 + \sin \theta} = \frac{1 - \sin \theta}{\cos \theta}
1+sinθ
cosθ
=
cosθ
1−sinθ
Answer:
sin^2(θ)+cos^2(θ)=1
Step-by-step explanation:
We know that the statement above is true because of the Pythagorean identity theorem, which states the aforementioned equation. If you solve the equation for 1 you get the same equation.
To do this first multiply both sides by cos(θ), this gives you (cos^2θ)/1+sinθ = 1-sinθ
Then, multiply both sides by sinθ. This equals cos^θ=1-sin^2θ.
Finally, add sin^2θ to both sides. This equals the final answer of cos^2θ+sin^2θ=1. Which is true.

7/3 + x=3;x math I really need help
Given:
The equation is:
[tex]\dfrac{7}{3}+x=3[/tex]
To find:
The value of x.
Solution:
We have,
[tex]\dfrac{7}{3}+x=3[/tex]
Subtract both sides by [tex]\dfrac{7}{3}[/tex].
[tex]\dfrac{7}{3}+x-\dfrac{7}{3}=3-\dfrac{7}{3}[/tex]
[tex]x=\dfrac{9-7}{3}[/tex]
[tex]x=\dfrac{2}{3}[/tex]
Therefore, the value of x is [tex]\dfrac{2}{3}[/tex] or it can be written as 0.667.
Bob drew a line he thought was close to many of the points and found the equation of the line. He used the points (165, 168) and (174, 178) on his line to find the equation. What is the equation of Bob’s line? If entering decimal values, round to the tenths place.
What does Bob’s equation predict for the height of a person with an arm span of 162 cm? If entering a decimal value, round to the tenths place.
Answer:a
Step-by-step explanation:
Answer:
y = (10/9)x - 138/9
Height of 164.7 cm for an arm span of 162 cm
Step-by-step explanation:
First we find the slope. (178 - 168)/(174 - 165) = 10/9
Now use the point-slope form of a line
y - 168 = 10/9(x - 165)
9y - 9(168) = 10(x - 165)
9y - 1512 = 10x - 1650
9y = 10x - 138
y = (10/9)x - 138/9
If the arm span is 162 cm, then x = 162
y = (10/9)(162) -138/9
= 180 - 15.3
= 164.7 cm
Lebron makes 5 cups of punch by mixing 3 cups of cranberry juice with 2 cups of apple juice. How much cranberry juice and how much apple juice does Lebron need to make 4 times the original recipe
Answer:
For 4 times the original recipe Lebron needs 12 cups of cranberry juice with 8 cups of apple juice.
Step-by-step explanation:
For 5 cups of punch Lebron needs 3 cups of cranberry juice with 2 cups of apple juice.
For 4 times the original recipe Lebron needs 3*4= 12 cups of cranberry juice with 2*4= 8 cups of apple juice.
He will get 20 cups of punch.
We multiply each ingredient of the original recipe by the factor 4 to get the required ingredients of the 4 times product as the original product.

A new apartment complex is opening in College Station. The rent for each apartment is determined by its size: $1,500 for a 3-bedroom apartment, $900 for a 2-bedroom, and $500 for 1-bedroom. If all the apartments are occupied for one month, the rent revenue will be $750,000. There are 200 more 1-bedroom apartments than the number of 2-bedroom and 3-bedroom apartments combined. There are a total of 1,550 bedrooms for all 1,000 apartments. Which system of equations can be used to determine the number of 1-bedroom apartments (x), the number of 2-bedroom apartments (y), and the number of 3-bedroom apartments (z)?
Answer:
500x + 900y + 1500z = 750,000 - - - (1)
x + y + z = 1000 - - - - (11)
x = 200 + y + z - - - - (111)
x + 2y + 3z = 1550 - - - (1V)
Step-by-step explanation:
I bedroom = x
2 bedroom = y
3 bedroom = z
All the condition s gjvbbs'
500x + 900y + 1500z = 750,000 - - - (1)
x + y + z = 1000 - - - - (11)
x = 200 + y + z - - - - (111)
x + 2y + 3z = 1550 - - - (1V)
