If a flat-screen television is a rectangle with a 53-inch diagonal and a width of 45 inches then the height of the screen is 28 inches.
What is a rectangle?A rectangle is a two-dimensional shape where the length and width are different.
The area of a rectangle is given as:
Area = Length x width
We have,
Diagonal of the television = 53 inches
Width = 45 inches
The height h of the television.
Applying the Pythagorean theorem.
h² + 45² = 53²
h² = 2809 - 2025
h² = 784
h = 28
Thus,
The height of the television is 28 inches.

Erin finds that an actual distance of 145 miles in her city is equivalent to 38 of an inch on a map. The map includes a legend that lists the number of miles represented by 1 inch. How many miles per inch are listed in the legend?
Answer:
3.82 miles per inch are listed in the legend.
Step-by-step explanation:
Given that:
Actual distance = 145 miles
Distance on map = 38 inches
38 inches = 145 miles
We have to find the number of miles represented by 1 inch.
1 inch on legend = [tex]\frac{Actual\ distance}{Distance\ on\ map}[/tex]
1 inch on legend = [tex]\frac{145}{38}[/tex]
1 inch on legend = 3.82 miles
Hence,
3.82 miles per inch are listed in the legend.

please help dont answer if u dont know the answer
Answer:
C. (-2, 0)
Step-by-step explanation:
[tex]y = 3x + 6[/tex]
[tex]y = 2x + 4[/tex]
Since both equations equal y, set them equal to each other.
[tex]3x + 6 = 2x + 4[/tex]
[tex]x + 6 = 4[/tex]
[tex]x = -2[/tex]
Substitute -2 for x in the first equation.
[tex]y = 3x + 6[/tex]
[tex]y = 3(-2) + 6[/tex]
[tex]y = -6 + 6[/tex]
[tex]y = 0[/tex]
[tex](-2, 0)[/tex]
Now, substitute the x- and y-values into the second equation.
[tex]y = 2x + 4[/tex]
[tex]0 = 2(-2) + 4[/tex]
[tex]0 = -4 + 4[/tex]
[tex]0 = 0[/tex]
It works! The soluton to the system of equations is (-2, 0).

Solve this equation: 6y+4-3y=-5+y+17
Answer:
y=4
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
6y+4−3y=−5+y+17
6y+4+−3y=−5+y+17
(6y+−3y)+(4)=(y)+(−5+17)(Combine Like Terms)
3y+4=y+12
3y+4=y+12
Step 2: Subtract y from both sides.
3y+4−y=y+12−y
2y+4=12
Step 3: Subtract 4 from both sides.
2y+4−4=12−4
2y=8
Step 4: Divide both sides by 2.
2y/2= 8/2 = y=4
have a nice day!!!
Answer:
Y=4
Step-by-step explanation:
First you have to Combine like terms, then Add the numbers, then Rearrange terms, then Subtract 4 from both sides of the equation, Simplify, Subtract y from both sides of the equation, Simplify, Divide both sides of the equation by the same term, and finally, simplify agian.

A fifteen foot ladder is placed against a wall. It reaches 13 feet up the wall. What is the longest distance away from the wall the ladder can be placed?
Answer:
Step-by-step explanation:
The question is phrased oddly, asking “how far *can* the ladder be from the wall,” instead of “how far *is* the ladder from the wall.”
Draw a picture. The 15-foot ladder is the hypotenuse of a right triangle. The vertical leg of the triangle is 13 feet.
By the Pythagorean Theorem, the remaining leg is √(15²-13²) ≈ 7.5 feet.
Note that the ladder *can* be 7.5 feet from the wall, but it *shouldn’t* be. The angle to the ground is 60°, when the recommended angle is 75°. That makes it. 3.9 feet
2.4,1.6,3.2,0.3,1.5 each piece of data is increased by 10 calculate the new mean
Answer:
The new mean is: 11.8
Step-by-step explanation:
Given the data set
2.4 1.6 3.2 0.3 1.5
Sum of terms = 2.4 + 1.6 + 3.2 + 0.3 + 1.5 = 9
Number of terms = 5
We know that the mean of a data set is the sum of the terms divided by the total number of terms, so
Mean = Sum of terms / Number of terms
substituting Sum of terms = 9 and Number of terms = 5
= 9/5
= 1.8
Thus, the Mean = 1.8
We need to determine the mean when each piece of data is increased by 10.
All we need is to add 10 in the determined mean to determine the new mean.
New Mean = Mean + 10
= 1.8 + 10
= 11.8
Therefore, the new mean is: 11.8
VERIFICATION:
When each piece of data is increased by 10
[tex]2.4+10+1.6+10+3.2+10+0.3+10+1.5+10=59[/tex]
so,
[tex]\frac{59}{5}=11.8[/tex]

A map is being reduced to from a pocket sized version. What is the scale factor being used to reduce the map?
Answer and explanation:
If a map is being reduced to form a pocket sized version then it is being proportionality reduced a smaller size that is required. Cartographers enlarge and reduce maps proportionally to serve different purposes in their study. The map is still the same but smaller in size.
If on a map 2cm represents 2 meters, that is 0.02/2 which evaluates to 1/100, then we are comparing distance and ensuring they are proportional using scale factor(our scale factor is 1:100 here)

Given that
3 x − 5 y = 15
Find y when x = 1
Give your answer as an improper fraction in its simplest form.
Answer:
y = - [tex]\frac{12}{5}[/tex]
Step-by-step explanation:
Given
3x - 5y = 15 ← substitute x = 1 into the equation
3(1) - 5y = 15
3 - 5y = 15 ( subtract 3 from both sides )
- 5y = 12 ( divide both sides by - 5 )
y = - [tex]\frac{12}{5}[/tex]
