The perimeter of a rectangle is 120 centimeters. The base is 3 times the height. What are the dimensions of the rectangle? a. h = 9cm, b = 18 cm c. h = 15 cm, b = 45 cm b. h = 19 cm, b = 57 cm d. h = 10 cm, b = 15 cm
Answer:
[tex]Height = 15[/tex]
[tex]Base = 45[/tex]
Step-by-step explanation:
Given
Shape: Rectangle
[tex]Perimeter = 120cm[/tex]
[tex]Base = 3 * Height[/tex]
Required
Determine the dimensions
The perimeter of a rectangle is:
[tex]Perimeter = 2 * (Base + Height)[/tex]
Substitute 120 for Perimeter
[tex]120 = 2 * (Base + Height)[/tex]
Divide both sides by 2
[tex]60 = Base + Height[/tex]
Substitute 3 * Height for Base
[tex]60 = 3 * Height + Height[/tex]
[tex]60 = 3Height + Height[/tex]
[tex]60 = 4Height[/tex]
Divide both sides by 4
[tex]15 = Height[/tex]
[tex]Height = 15[/tex]
Substitute 15 for Height in [tex]Base = 3 * Height[/tex]
[tex]Base = 3 * 15[/tex]
[tex]Base = 45[/tex]

23
Step-by-step explanation:
12, 65, 3, 8, 23, 64, 19, 53, 0, 24, 57, 15, 39
First put in order.
0, 3, 8, 12, 15, 19, 23, 24, 39, 53, 57, 64, 65
Eliminate each number alternating from beginning and end like so.
3, 8, 12, 15, 19, 23, 24, 39, 53, 57, 64
Keep doing until you get to the middle.
8, 12, 15, 19, 23, 24, 39, 53, 57
12, 15, 19, 23, 24, 39, 53
15, 19, 23, 24, 39
19, 23, 24
23
Since 23 is the last remaining number, that is the median.

Answer:
1178 inches
Step-by-step explanation:
Using the triangle I drew (assuming n is across from ∠N), we can conclude that ∠O = 180-97-32 = 51 as the angles in a triangle add up to 180.
Using the law of sines, we can conclude that
[tex]\frac{o}{sinO} = \frac{n}{sinN} \\[/tex]
Plugging our values in, we get
[tex]\frac{o}{0.78} = \frac{800}{0.53}[/tex]
Multiply both sides by 0.78 to get
[tex]o = \frac{800*0.78}{0.53} = around 1177.5[/tex]
round up to get 1178 as our answer

hope this helps
The length of radius is 7.81 unit.
What is Distance Formula?The distance between two points P(a, b)a nd Q(c, d) is
D = √(c- a)² + (d- b)²
Given:
Center at (-2,7) if a point on the circle has coordinates (3,-1).
Using Distance Formula
D = √( 3-(-2))² + (1-7)²
D = √ (3 +2)² + (-6)²
D = √5² + 36
D = √25+36
D = √61
D= 7.81 unit
Hence, the length of radius is 7.81 unit.

A 20-question math test is worth 100 points.Multiple choice questions worth 4 points each.Bubble grid questions are worth 8 points each.How many of each type of question is on the test?
Answer:
There are 5 8-point questions and 15 4-point questions
Step-by-step explanation:
20.4= max points 80 limit of points = 100
20.8= max points 160
100:4= max 25 questions limit of questions = 20
100:8= max 12,5 question
5.8=40
15.4=60
There are 5 bubble grid questions and 15 multiple choice questions.
What is Equation?Two or more expressions with an Equal sign is called as Equation.
Let,
Multiple choice questions denoted by M
Bubble grid questions are denoted by B
A 20-question math test is worth 100 points.
M+B=20..(1)
Multiple choice questions worth 4 points each. Bubble grid questions are worth 8 points each.
4M+8B=100..(2)
From equation 1,
M=20-B
4(20-B)+8B=100
80-4B+8B=100
80+4B=100
Subtract 80 from both sides
4B=20
Divide both sides by 4
B=5
Now plug in B value in equation 1.
M+5=20
Subtract 5 from both sides
M=15
Hence, there are 5 bubble grid questions and 15 multiple choice questions.

Step-by-step explanation:
Sum of angles in a triangle is 180 degrees
180-40-60 = 80
80 degrees
80 degrees is an acute angle.
Answer:
It would be 80 degrees which is an acute angle
Step-by-step explanation:
A triangle is 180 degrees in total 60 degrees + 40 degrees is 100 degrees leaving you with 80 degrees its acute because, 0 degrees to 90 degrees is an acute angle. Hope this helped!

does anyone know the values of x and y? my teacher didn’t go over this type of problem
Answer:
x = 80
y = 100
Step-by-step explanation:
First, we need to figure out how many degrees there are in total in the inside of the polygon. There are 7 sides, so now let's use the formula to find out the total degrees.
(n - 2) * 180
"n" is the amount of sides.
(7 - 2) * 180 =
5 * 180 =
900
The total degrees is 900.
Now, we have to add all the sides in the inside to form an equation to solve for y.
y + 135 + 140 + 150 + 120 + 135 + 120 = 900
y + 800 = 900
y + 800 - 800 = 900 - 800
y = 100
Now, we know that x and y are supplementary angles. So the sum of x and y is 180. We can use that to create an equation to solve for x!
x + y = 180
x + 100 = 180
x + 100 - 100 = 180 - 100
x = 80
Therefore, x = 80 and y = 100

What property can be used to simplify the expression:
27(2p + 4e + 10p + 20)
can someone help me out?
Answer:
y is equal to nine and two thirds, or 9.666...
Step-by-step explanation:
To solve this, we first need to know the value of x. We can see though that x + (x - 12) is equal to 180 degrees, so:
x + 5x - 12 = 180
6x = 192
x = 32
Now that we have x, we can use the same rule to solve for y:
3y - 8 = x
3y - 8 = 32
3y = 40
y = 40 / 3
So y = 40/3, or 9 and 2/3
Bonus:
I almost wonder if the question was printed incorrectly, as the answer would have been a nice tidy integer if the other corner was 3y + 8 instead of 3y - 8.
If that were the case we'd have:
3y + 8 = 32
3y = 24
y = 8
A nice clean answer
To be clear, this last bit is NOT the correct answer, just an observation. If the book tells you that eight is the answer, then the question is misprinted.

Maddie's bedroom is rectangular. The length of one wall of Maddie's bedroom is 4 meters. The length from one corner of the bedroom to the diagonally opposite corner is 5 meters. What is the length of the other wall?
Answer:
The length of other wall is 3 meters.
Step-by-step explanation:
Given that:
Length of one wall = 4 meters
Length of diagonal from one corner to opposite corner = 5 meters
As the room is rectangular, the diagonal will form a right angled triangle.
The diagonal will be the hypotenuse.
Using pythagorean theorem;
[tex]a^2+b^2=c^2[/tex]
Here,
a = 4 and c = 5
[tex](4)^2+b^2=(5)^2\\16+b^2=25\\b^2=25-16\\b^2=9[/tex]
Taking square root on both sides
[tex]\sqrt{b^2}=\sqrt{9}[/tex]
b = 3 meters
Hence,
The length of other wall is 3 meters.

(Please i need help) The expression p - 0.15p can be used to calculate the final cost of an item that has a price of p and is
discounted 15%.
What is the final cost of an item that has an original price of $23?
Enter your answer as the correct value with two decimal places, like this: 42.53
Answer:
Final cost of the item is $19.55
Step-by-step explanation:
Expression representing the final cost of an item with original price = $p and discount = 15% will be,
Final cost = (p - 0.15p)
If the original price p = $23
By substituting p = 23 in the expression given,
Final cost after discount = 23 - (0.15)23
= 23 - 3.45
= $19.55
Therefore, final cost of the item is $19.55
