Answer:
If the model is 3 inches tall, the model bookcase should be 2 inches wide.
Step-by-step explanation:
When using similar figures, set up a proportion of the model measurements to the actual measurements:
[tex]\frac{3}{48}=\frac{x}{32}[/tex]
Then cross multiply and solve for x:
[tex]48x=96\\x=\frac{96}{48}\\x=2[/tex]

Angharad is buying a new 40-inch screen TV (remember that TV screens are measured along the diagonal )
a)If it is 20 inches tall, how wide is the screen ?
b)Her TV cabinet is 30 inches wide .will the TV fit inside it ?
Answer:
a) 34.64 inches
b) The TV will not fit inside the TV cabinet
Step-by-step explanation:
Angharad is buying a new 40-inch screen TV (remember that TV screens are measured along the diagonal )
a)If it is 20 inches tall, how wide is the screen ?
We solve using the formula:
Diagonal ² = Width² + Height²
Diagonal = 40 inches
Height = 20 inches
40² = Width² + 20²
Width² = 40² - 20²
Width = √40² - 20²
Width = √(1200)
Width = 34.641016151 inches
Approximately = 34.64 inches
b)Her TV cabinet is 30 inches wide .will the TV fit inside it ?
From the above calculation, the width of the TV = 34.64 inches
Hence the width of the cabinet has to be equal to or more than 34.64 inches
Hence, The TV will not fit inside the TV cabinet

Suppose the two line segments in a coordinate plane one with a length of 120 units and other with a length of 240 units were both rotated 90 degrees about the origin and then translated 50 units up one of the resulting segments could have a length of...Units.
Answer:
[tex]Line\ 1 = 120\ units[/tex]
[tex]Line\ 2 = 240\ units[/tex]
Step-by-step explanation:
Given
[tex]Line\ 1 = 120\ units[/tex]
[tex]Line\ 2 = 240\ units[/tex]
Transformation
Rotation: 90 degrees
Translation: 50 units up
Required
The new length of one of the lines
Since no options were given, I will solve for the lengths of the two lines
From the question, the transformations are rotation and translation. These two types of translation do not alter the length or angle of a shape.
This implies that both lines will still retain their original lengths.
So. we can conclude that, after the transformation
[tex]Line\ 1 = 120\ units[/tex]
[tex]Line\ 2 = 240\ units[/tex]

Due 03/24/21 11:5 Exit 4-6: MathXL for School: Practice & Problem Solving Question Help X 4.6.PS-13 Design An art class is making a mural for their school which has a triangle drawn in the middle. The length of the bottom of the triangle is x. Another side is 10 more than three times the length of the bottom of the triangle. The last side is 1 more than the bottom of the triangle. plz hurry!!!
Answer:
[tex]x < - 9[/tex]
Step-by-step explanation:
We can only find the range of the values of x by using triangle inequality,
[tex]x + 1 + x > 3x + 10 \\ \\ 1 - 10 > 3x - 2x \\ \\ - 9 > x[/tex]
Multiply through both sides by -1, we get,
[tex]x < - 9[/tex]
This means x = -10, -11, ... (which is not realistic because a side of a triangle cannot be a negative number)

Which equation can be used to solve 3a = 15?
A. a = 15 ÷ 3
B. a = 15 • 3
C. a = 15 + 3
D. a = 15 – 3
Answer: a
Explanation:
3a=15 is the same thing as the expression 15 divided by 3
3) Valerie works at a local amusement park. She earns $9.80 per hour. She 20 points
also receives $10 for meals daily. Last Friday, Valerie earned $88.40.
Which equation can be used to determine how many hours Valerie
worked on Friday? *
a. 9.80h + 10 = 88.40
b. 88.40h + 9.80 = 10
c. 10h + 88.40 = 9.80
d. 10h + 9.80 = 88.40
===========================================================
Work Shown:
h = number of hours worked.9.80h = amount of money earned after working h number of hours (ignoring the meal bonus).9.80h+10 = total amount of money earned after adding on the meal bonus.9.80h+10 = 88.40 is the equation we use since the total 9.80h+10 is the same as the total she earned 88.40 dollars.--------------------
Extra info (optional section)
If you want to solve for h, then you could follow these steps.
9.80h+10 = 88.40
9.80h = 88.40-10 ... subtract 10 from both sides
9.80h = 78.40
h = 78.40/9.80 .... divide both sides by 9.80
h = 8
Valerie worked 8 hours on Friday.
As a check,
9.80h + 10 = 88.40
9.80*8 + 10 = 88.40
78.40 + 10 = 88.40
88.40 = 88.40
The answer is confirmed.
I need to solve for x this is easy I don't have the time to do it though
A 10-foot ladder touches the side of a building at a point 8 feet above the ground. At what height would a 22-foot ladder touch the building if it makes the same angle with the ground as the shorter ladder? Round to the nearest tenth if necessary.
8.75 feet
Step by step:Given that a 12 foot ladder leans against a building seven feet above the ground.
By using trigonometry ratio, the angle between the ladder and the ground will be
SinØ = opposite/ hypothenus
SinØ = 7 / 12
SinØ = 0.58333
Ø = Sin^-1(0.58333)
Ø = 35.69 degree
At what height would an 15 foot ladder touch the building if both ladders form the same angle with the ground?
Using the same trigonometric ratios
SinØ = opposite/hypothenus
Sin 35.69 = opposite/ 15
Cross multiply
Opposite = 15 × sin 35.69
Opposite = 8.75 feet
Therefore, the ladder will touch the building if both ladders form the same angle with the ground at height 8.75 feet.
