What is the value of x?
12 units
16
0
15 units
O
20 units
R
Х
Q
0
24 units
Answer:
C. 20 units
Step-by-step explanation:
x > 16 because the hypotenuse is always the longest side
9 + 16 = 25
25 > x
that leaves you with 20 units and 24 units but 24 units is too long, so C. 20 units is the answer
Tthe value of x is 20 u
To get the value of x from the diagram, we will use the triangle altitude theorem as shown below;
From the diagram;
9/RT = RT/16
RT^2 = 9*16
RT^2= 144
RT = 12
Get the value of x using the pythagoras theorm;
x^2 = 16^2 + 12^2
x^2 = 256 + 144
x^2 = 400
x = 20
Hence the value of x is 20 units

What did my teacher do to get the answer to this question?
Step-by-step explanation:
since perimeter is adding all around she took the all the values and added them as above. as you can see 3√2 and 4√2 has the same square root so she added 3+4 which gave us 7√2 and then added the 2√5 but since they don't have the same square root we can't add them like we did in the other so we'll just put 7√2+2√5

29-3x=5x+5
Can you work it out
Answer:
x=3
Step-by-step explanation:
29 - 3x = 5x + 5
Subtract 5 from both sides:
24 - 3x = 5x
Add 3x to both sides:
24 = 8x
Divide both sides by 8:

Jan tossed a coin 50 times and got a head 20 times. What is the
experimental probability? What is the theoretical probability?
Answer:
The standard answer for this is 50%.
Step-by-step explanation:
However, this is based on the implicit assumption that the coin is fair.
If there are reasonable grounds to doubt that the coin is fair, the theoretical probability must be based on observed statistics. In this scenario, the probability is 60%.

what are the common factors of 20 and 24
Answer:
4
Step-by-step explanation:
4 x 5= 20
4x6 = 24
So 4 can go in 20 and 24 making it the common factor
The common factor of 20 and 24 would be; 4
How to find Greatest common factor?Greatest common factor, as the nathe me implies, is greatest among all common factors among the quantities given. We can factorize the quantities in smallest relative factors possible (one level of factors over which all quantities can form themselves), and collect as many common factors as we could. Those will together greatest GCF(Greatest common factor).
We need to find the common factors of 20 and 24
Therefore,
Factors are;
4 x 5= 20
4 x 6 = 24
Hence, we can conclude that 4 can go in 20 and 24. it is the common factor.
The common factor of 20 and 24 would be; 4

When a decimal is written in word form, what indicates whether the number can be written as a mixed number or as a fraction less than 1
9514 1404 393
Answer:
"and"
Step-by-step explanation:
Properly written, the word "and" separates the integer portion from the fractional portion of the number. If there is no "and", then there is no integer portion, so the number is a fraction less than 1.
Examples:
one and three tenths = 1 3/10
thirty-one thousandths = 31/1000

Brendan worked 7 11/12 hours on Saturday, on Sunday he worked 84% of the hours he worked on Saturday. How many total hours do he work last weekend?
Answer:
[tex]14\frac{17}{30}[/tex]hrs
Step-by-step explanation:
Given parameters:
Time worked on Saturday = [tex]7\frac{11}{12}[/tex]
Unknown:
Total hours he worked last weekend = ?
Solution:
Since Brendan worked 84% of the time he worked on Saturday on Sunday;
Time worked on Sunday = [tex]\frac{84}{100}[/tex] x [tex]\frac{95}{12}[/tex] = [tex]\frac{133}{20}[/tex]
Total time worked last weekend = Time worked on Saturday + Time worked on Sunday;
Total time worked = [tex]\frac{95}{12}[/tex] + [tex]\frac{133}{20}[/tex]
Total time worked = [tex]\frac{475 + 399}{60}[/tex]
Total time worked = [tex]\frac{874}{60}[/tex]
Total time worked = [tex]\frac{437}{30}[/tex] = [tex]14\frac{17}{30}[/tex]hrs

The given expression 3/4 x 3/4 x 3/4 x 3/4 x 3/4 can be written as (3/4)⁵ in the form of an exponent.
What is the expression?Expressions are defined as mathematical statements that have a minimum of two terms containing variables or numbers.
An exponent is a shorthand way of representing a repeated multiplication of the same number.
As per the given question, the number being multiplied is 3/4, and it is being multiplied by itself 5 times. The exponent, 5, tells us how many times the base, 3/4, is being multiplied by itself.
⇒ 3/4 x 3/4 x 3/4 x 3/4 x 3/4
⇒ (3/4)⁵
Therefore, the given expression can be written as (3/4)⁵.

Answer:
1. perimeter of Trapezoid = 35x+18
Option F is correct.
2. perimeter of square = 16x-32
Option C is correct.
3. perimeter of Pentagon = 10x-20
Option A is correct.
4. perimeter of Rhombus = 28x+8
Option H is correct.
Step-by-step explanation:
1. Trapezoid Perimeter
Side1 a: 9x+4
Side2 b: 7x+8
Side3 c: 12x-2
Side4 d: 7x+8
The formula used is: [tex]Perimeter=a+b+c+d[/tex]
Putting values and finding perimeter
[tex]Perimeter=a+b+c+d\\Perimeter=9x+4+7x+8+12x-2+7x+8\\Perimeter=9x+7x+12x+7x+4+8-2+8\\Perimeter=35x+18[/tex]
So, perimeter = 35x+18
Option F is correct.
2. Square Perimeter
Side of square = 4x-8
The formula used is:[tex]Perimeter=4a[/tex]
where a is side of square
Putting values in formula
[tex]Perimeter=4a\\Perimeter=4(4x-8)\\Perimeter=16x-32[/tex]
So, perimeter of square = 16x-32
Option C is correct.
3. Pentagons perimeter
Side of pentagon= 2x-4
The formula used is:[tex]Perimeter=5a[/tex]
where a is side of pentagon.
Putting values in formula
[tex]Perimeter=5a\\Perimeter=5(2x-4)\\Perimeter=10x-20[/tex]
So, perimeter of Pentagon = 10x-20
Option A is correct.
4. Rhombus perimeter
Side of Rhombus=7x+2
The formula used is:[tex]Perimeter=4a[/tex]
where a is side of rhombus
Putting values in formula
[tex]Perimeter=4a\\Perimeter=4(7x+2)\\Perimeter=28x+8[/tex]
So, perimeter of Rhombus = 28x+8
Option H is correct.
Jayme was almost finished running the Los Angeles Marathon. So far, she has ran 25 miles in 6 hours. At the same rate, how long would it take her to do a 100 miles Triathlon?
Answer:
24 hours because if she travels 25 miles in 6 hours and you multiply 25 by 4 to get 100, you need to multiply 6 by 4 in order for how long it takes her to run 100 miles. 6 X 4 = 24 hours
4x - 4 - 8y + 8 - 5x + 1 =
Answer:
-x - 8y + 5
Step-by-step explanation:
Add the numbers
4x - 4 - 8y + 8 - 5x + 1 =
4x + 5 - 8y - 5y
Combine like terms
4x + 5 - 8y - 5y
-x + 5 - 8y
Rearrange terms
-x + 5 - 8y
-x - 8y + 5
The solution of expression is,
⇒ - x - 8y + 5
We have to given that,
An expression is,
⇒ 4x - 4 - 8y + 8 - 5x + 1
Now, We can simplify by combining like terms as,
⇒ 4x - 4 - 8y + 8 - 5x + 1
⇒ 4x - 5x - 8y - 4 + 8 + 1
⇒ - x - 8y + 5
Therefore, The solution of expression is,
⇒ - x - 8y + 5
