Find the value of x that makes each parallelogram the given type (answer both please)
Answers
Answer:
a. x = 12
b. x = 4
Step-by-step explanation:
a. RECTANGLE
ABCD is a rectangle, AC and BD are its diagonals.
Diagonals of a rectangle are congruent.
Therefore,
AC = BD
10x + 8 = 9x + 20
10x - 9x = 20 - 8
x = 12
b. RHOMBUS
Diagonal of a rectangle bisect opposite angles.
Therefore,
(5x + 3)° = (2x + 15)°
5x + 3 = 2x + 15
5x - 2x = 15 - 3
3x = 12
x = 12/3
x = 4
The value of x for a rectangle will be 12.
The value of X for a rhombus is 4.
What is a parallelogram?A basic quadrilateral containing two sets of side lengths is known as a parallelogram. There are four types of parallelograms each with diffrent kinds of properties.
a. RECTANGLE
ABCD is a rectangle, Therfore the diagonals that are made will also be equal.
AC = BD
[tex]10x +8 = 9x + 20\\10x - 9x = 20 - 8[/tex]
x = 12
b. RHOMBUS
As this is a rhombus that is presented, the angle which is divided with the help of the diagonal will both be equal.
5x + 3 = 2x + 15
5x - 2x = 15 - 3
Simplifying the equation,
3x = 12
x = 12/3
x = 4

Solve for v2
[tex]a \: ave = \frac{v2 - v1}{t2 - t1} [/tex]
Answers
Answer:
Solving the given formula for v2 gives us:
[tex]a(t_2-t_1)+v_1 = v_2[/tex]
Step-by-step explanation:
Solving an equation for a particular variable means that the variable has to be isolated on one side of the equation.
Given equation is:
[tex]a = \frac{v_2-v_1}{t_2-t_1}[/tex]
Multiplying both sides by t2-t1
[tex](t_2-t_1) . a = \frac{v_2-v_1}{t_2-t_1} . (t_2-t_1)\\a(t_2-t_1) = v_2-v_1[/tex]
Adding v1 to both sides of the equation
[tex]a(t_2-t_1)+v_1 = v_2-v_1+v_1\\a(t_2-t_1)+v_1 = v_2[/tex]
Hence,
Solving the given formula for v2 gives us:
[tex]a(t_2-t_1)+v_1 = v_2[/tex]
How many 5-digit personal identification numbers are possible if the number cannot contain a
zero?
Answers
Answer:
59049 digits
Step-by-step explanation:
Given
Digits = 0 to 9
Required
Determine number of 5 digit pins that must not contain 0
There are 10 digits.
Since the pin must not contain 0, there are 9 digits left to select from.
The question didn't state that a digit can not be repeated, so I'll assume that repetition of digit is allowed.
The 1st digit of the 5 could be any of the 9 digits
The 2nd could be any of the 9 digits
The 3rd could be any of the 9 digits
The 4th could be any of the 9 digits
The 5th could be any of the 9 digits
Hence, number of selection is calculated as this:
Selection = 9 * 9 * 9 * 9 * 9
Selection = 59049

Sally went to the clearance rack at a department store and found a shirt she wanted to buy. The shirt was $36.00 and is on sale for $24.00. What is the percent of the decrease?
Answers
Answer:
33.34%.
Step-by-step explanation:
Given that,
The actual price of the shirt = $36
Price on sale = $24
We need to find the percent of the decrease. The formula for the percentage is given by :
[tex]\%=\dfrac{|\text{actual value-estimated value}|}{\text{actual value}}\times 100[/tex]
Putting all the values,
[tex]\%=\dfrac{24-36}{36}\times 100\\\\=33.34\%[/tex]
So, the percentage decrease in the price of the shirt is 33.34%.

x and the 35 degree angle are supplementary angles, so x + 35 = 180.
solve for x, x = 145. the 35-degree angle and angle Y are corresponding angles, so the value of y will be 35.

Answers
Answer:
1. Y = 2, 1, 4, 7, 10
2. Y = -12, -8, -4, 0, 4
3. Y = -7, -5, -3, -1, 1
Step-by-step explanation:
all of the numbers in the x value you just substitute in the x place in problem
1. Y = 3x + 4
x: -2, -1, 0, 1, 2
Y = 3(-2) + 4
Y = -6 + 4
Y = -2
You then have:
x: -2, -1, 0, 1, 2
y: -2,
Y = 3(-1) + 4
Y = -3 + 4
Y = 1
You then have:
x: -2, -1, 0, 1, 2
y: -2, 1
just continue substituting each x variable into the x place to get your y variable.
