Television sizes are described by the length of their diagonal measure. What would be the listed size of the TV shown? (To the nearest whole inch)
Answer:
The listed size is 32 inches
Step-by-step explanation:
Given
See attachment for television
Required
The listed size
The listed size is calculated by the diagonal of the television.
This is calculated as using Pythagoras theorem as follows:
[tex]Diagonal^2 = Length1^2 + Length2^2[/tex]
Where:
[tex]Length1 =28in[/tex]
[tex]Length2 =15.7in[/tex]
So, we have:
[tex]Diagonal^2 = 28^2 + 15.7^2[/tex]
[tex]Diagonal^2 = 784 + 246.49[/tex]
[tex]Diagonal^2 = 1030.49[/tex]
Take positive square roots of both sides
[tex]Diagonal = \sqrt{1030.49[/tex]
[tex]Diagonal = 32[/tex] --- approximated
Hence, the listed size is 32 inches
Solve the equation below:
(find x)
Answer:
X=-8
Step-by-step explanation:
3x-4=7×-4
3x-4=-28
3x=-28+4
3x=-24
x=-24/3
x=-8
Answer:
[tex]x =-8[/tex]
Step-by-step explanation:
Hello!
Remove the fraction by multiplying both sides by 7. Solve for x by isolating the variable.
Solve for x[tex]\frac{3x - 4}{7} = -4[/tex][tex]3x - 4 = -28[/tex][tex]3x = -24[/tex][tex]x = -8[/tex]The value of x is -8.
What is the common ratio of the sequence?
-2, 6, -18, 54
Answer:
The common ratio of the sequence is -3
Step-by-step explanation:
The reason why the answer is -3 because every single number is multiplied by -3. If you need an explanation on how I found it, here it is:
To determine the common ratio by dividing each number in the sequence from the number preceding it. If the same number is not multiplied to each number in the series, then there is no common ratio.
Use the distributive property to simplify each expression.

Given the isosceles trapezoid EFGH and side length JL = 93 units. If the length of KN = (3x + 1) and MN = (5x - 4), what is the length of KM?
Answer:
KM=JL=93 units
or KM=KN + MN= 8x-3
Step-by-step explanation:
The value of length of KM can be equal to either JL or obtained by adding KN = (3x + 1) and MN = (5x - 4) depending on the diagram.
An isosceles trapezoid has non parallel sides congruent.
In the isosceles trapezoid the diagonals are also equal.
There is a pair of parallel lines in an isosceles trapezoid.
In the 1st figure trapezoid JL and KM are diagonals.
If we take the JM and KL to be the parallel lines then the opposite sides can be JK and LM
And N is the middle line or the mid segment.
In the figure 2
The value of length of KM is obtained by adding KN = (3x + 1) and MN = (5x - 4)
KM=KN + MN = (5x - 4) +(3x + 1)
KM=8x- 3

.find the slope and y intercept form equation from the table
Answer:
y = 4x - 26
Step-by-step explanation:
The change in y is 4 when the change in x is 1.
So the slope is change in y/change in x = 4/1 = 4
y = mx + b
30 = 4(14) + b
30 = 56 + b
b = - 26
Therefore, y = 4x - 26
A triangle has two sides of length 17 and 19. What is the smallest possible whole-number length for the third side?
Answer:
3
Step-by-step explanation:
A triangle has two sides of length 17 and 19. What is the smallest possible whole-number length for the third side?
To solve for the above question, a rule applies.
The rule states that:
The sum of any 2 sides must be greater than than the third side.
The possible values for the third side are
19 - 17 < x < 19 + 17( x is the third side )
2 < x < 36
Thus the smallest possible whole number is 3

Each hour, every person who knows a rumor tells two other people. If one person starts the rumor, then after the first hour, three people know the rumor. The next hour, those three people each tell two more people. After eight hours, how many people will know the rumor? You do not have to include units in your answer.
Answer:
384
Step-by-step explanation:
if each person who knows it tell 2 people then its doubling every hour
and for 8 hours the equation is

HELP PLS
Answer:
12x² + 17x - 5
Step-by-step explanation:
Given
(3x + 5)(4x - 1)
Each term in the second factor is multiplied by each term in the first factor, that is
3x(4x - 1) + 5(4x - 1) ← distribute parenthesis
= 12x² - 3x + 20x - 5 ← collect like terms
= 12x² + 17x - 5
