What value of x will make parallelogram ABCD a rhombus?
x = ?
Answer:
x=34
Step-by-step explanation:
3x-12=90
3x-12+12=90+12
3x=102
3x/3 = 102/
x=34
Answer:
x = 34Step-by-step explanation:
From the picture we have
AD = CD = BC = AB
it's enough to say that this quadrangle is a rhombus.
The diagonals in each rhombus are perpendicular and divide to half.
Therefore we have the equation:
3x - 12 = 90 add 12 to both sides
3x - 12 + 12 = 90 + 12
3x = 102 divide both sides by 3
3x : 3 = 102 : 3
x = 34

Answer:
6, -5/2, 7/4
Step-by-step explanation:
The required slope that shows given points are not collinear is 6, -5/2, and 7/4.
What is the slope of the line?
The slope of the line is a tangent angle made by line with horizontal. i.e. m =tanx where x in degrees.
Here,
m = (y₂ - y₁) / (x₂ - x₁) - - - - (1)
Substitute points C(1, 1), and D(3, -4) in the above equation 1,
m = -4 -1 / 3 - 1
m = -5/2
Substitute points D(3, -4) and E(5, 8) in the above equation 1,
m = 8 + 4 / 5 - 3
m = 12 / 2
m = 6
Substitute points C(1, 1) and E(5, 8) in the above equation 1,
m = 8 - 1 / 5 - 1
m = 7 / 4
Thus, the required slope that shows given points are not collinear are 6, -5/2, and 7/4.

Caleb went to Kroger and spent $83.47 on groceries. He had a coupon for $1.99 off bottled water and $0.89 off organic strawberries. How much did Caleb spend at Kroger?
Answer:
$86.35
Step-by-step explanation:
Total amount he spent at Kroger
= $83.47 on groceries. +coupon for $1.99 off bottled water + $0.89 off organic strawberries
= 83.47+0.89+1.99
= $86.35
Final answer:
After applying coupons for bottled water and organic strawberries, Caleb spent a total of $80.59 at Kroger. The discounts of $1.99 and $0.89 were subtracted from the initial spend of $83.47.
Explanation:
Caleb went to Kroger and initially spent $83.47 on groceries. He had two coupons: one for $1.99 off bottled water and another for $0.89 off organic strawberries. To calculate how much Caleb spent after using his coupons, we need to subtract the value of the coupons from the initial amount.
First, we calculate the total discount by adding the two coupon values:
$1.99 for bottled water
$0.89 for organic strawberries
Total discount = $1.99 + $0.89 = $2.88.
Then, we subtract this total discount from the initial spend:
$83.47 - $2.88 = $80.59
Therefore, Caleb spent $80.59 at Kroger after applying his coupons.

Eff scored a 23/25 on his math test, Maria scored 21/24 on her math test and Jake scored 17/20 on his math test. Who had the highest score? Explain how you know.
Answer:
Eff
Step-by-step explanation:
Fraction is a part of a whole, telling us how many parts of a whole we have. It can be converted to percentage or decimal.
Eff scored a 23/25 on his math test. Converting to percentage, eff score = 23/25 * 100% = 92%
Maria scored 21/24 on her math test. Converting to percentage:
Maria score = 21/24 * 100% = 87.5%
Jake scored 17/20 on his math test, converting to percentage:
Jake score = 17/20 * 100% = 85%
The person with the highest score has the highest percentage which is Eff with 92%.
Answer:
Eff had the highest score.
Step-by-step explanation:
The approach to determine who get the same score is converting each fraction to an arbitrary scale, which is 100 for this problem. Now, the conversions are presented below:
Eff
[tex]x = \frac{23}{25}\times 100[/tex]
[tex]x = 92[/tex]
Maria
[tex]x = \frac{21}{24}\times 100[/tex]
[tex]x = 87.5[/tex]
Jake
[tex]x = \frac{17}{20}\times 100[/tex]
[tex]x = 85[/tex]
Eff had the highest score.

The length of a rectangle is 5 inches more than the width. The area is 33 square inches. Find the length and width . Round to the nearest tenth if necessary.
Answer:
the length and width . Round to the nearest tenth are 8.8 inches and 3.8 inches respectively.
Step-by-step explanation:
The area A of a rectangle is the product of the length L and width W. This may be expressed mathematically as
A = L * W
As such, given that the length is 5 inches more than the width,
L = W + 5
33 = W(W + 5)
W² + 5W - 33 = 0
Using the formula method which states that
s = -b±√(b²-4ac)/2a
W = -5 ± √5² - 4(1)(-33)/2
= -5 ± 12.53/2
= 7.53/2 (since length cannot be negative)
= 3.755 inches
L = 3.755 + 5
= 8.755 inches
Can somebody please tell me the answer to this
Answer:
x= 60°.
Step-by-step explanation:
To solve this problem, we must figure out the measure of the angles inside a hexagon. We can do this using the Interior Angle formula S = (n - 2)·180.
When we plug the number of sides a hexagon has into this equation, we get a total sum of 720.
To get the measure of each angle, we simply divide 720 by 6, giving us a measure of 120 per angle. Since we know the measure of the interior angles, we can solve for angles of the triangle using Supplementary angles.
180-120= 60°.
We know that the two angles of the triangle against the hexagon are 60°, but what about the other angle?
All you need to do is subtract the two angles from 180 to get you the angle of 'x'.
180-2(60°)= 60°.
You open a business selling school supplies and tutoring sessions. In your first week, you had $9,000 in sales. You ran a promotion on tutoring sessions totaling $900 in discounts. Your returns equaled $150. Calculate total net sales.
Answer: total net sales = $7950
Step-by-step explanation:
The formula for determining total net sales is expressed as
total net sales = Gross sales - (sales returns + allowances + discount)
Gross sales means total sales.
From the information given,
Gross sales = $9000
Discounts = $900
Returns = $150
Allowances = 0(this is because it was not given)
Therefore,
total net sales = 9000 - (900 + 150)
= 9000 - 1050
total net sales = $7950
Answer:
7950

In how many ways can the first 4 guests arrive at a party if 15 guests have been invited.
Answer:
The first 4 guests can arrive in 32,760 ways.
Step-by-step explanation:
The order in which the guests arrive is important. For example, A,B,C,D is a different outcome to B,A,C,D. So we use the permutations formula to solve this question.
Permutations formula:
The number of possible permutations of x elements from a set of n elements is given by the following formula:
[tex]P_{(n,x)} = \frac{n!}{(n-x)!}[/tex]
In this question:
4 guests from a set of 15. So
[tex]P_{(15,4)} = \frac{15!}{(15-4)!} = 32760[/tex]
The first 4 guests can arrive in 32,760 ways.
Answer:
the first 4 guests can arrive in 32,760 ways.
Step-by-step explanation:
how many ways can the first 4 guests arrive at a party if 15 guests have been invited.
Permutations formula:
The number of possible permutations of x elements from a set of n elements is given by the following formula:
[tex]P_{(n,x)} = \frac{n!}{(n-x)!}[/tex]
4 guests from a set of 15
P(15,4) = 15 * 14 * 13 * 12
= 32760
Therefore, the first 4 guests can arrive in 32,760 ways.

Let S = {All students of 8th grade} = 91
A = {Students in Art} = 68
B = {Students in band} = 31
Part A : A∪B = A + B - A∩B
A∪B = 68 + 31 - 18
A∪B = 81
A∪B represents the total number of students enrolled in art and band.
Part B : A∩B = 18
A∩B represents the number of common students enrolled in art and band.

Mrs. Allard asked her students to identify which of the polynomials below are in standard form and explain why.
1. 15x4 - 6x + 3x2 - 1
II. 12x3 + 8x + 4
III. 285 + 8x2 + 10%
Which student's response is correct?
Answer:
Only II. is written in standard form
Step-by-step explanation:
The three polynomials given are:
I. [tex]15x^4 - 6x + 3x^2 - 1[/tex]
II. [tex]12x^3 + 8x + 4[/tex]
III. [tex]285 + 8x^2 + 10%[/tex]
A polynomial is said to be in standard form when the variables are written in terms of descending powers i.e. the term with the highest power first, followed by the next and so on.
Examining the three polynomials I, II and III, there is only one which follows this rule and that is:
II. [tex]12x^3 + 8x + 4[/tex]
The term with the highest power (3) came first, followed by the term with the next degree of power (1) and the last term with degree of power as 0.
Hence, only II. is written in standard form.
Only the second polynomial, 12x3 + 8x + 4, is in standard form because its terms are arranged in descending order of degrees. The first polynomial is not in standard form due to the incorrect order of terms by degree. The third expression contains a percentage sign (%) and wasn't written in order of descending degree, hence it doesn't qualify as a polynomial in standard form.
Explanation:In mathematics, a polynomial is said to be in standard form when its terms are written in descending order by degree. The degree of a term is the exponent used in the term. Let's evaluate each option:
15x4 - 6x + 3x2 - 1: This polynomial is not in standard form because the terms are not arranged in descending order of degrees. Properly ordered, it would read 15x4 + 3x2 - 6x - 1.12x3 + 8x + 4: This is in standard form because the terms are arranged in descending order of degrees from 3 to 0.285 + 8x2 + 10%: This is not a polynomial in the standard sense of the word due to the presence of the percentage sign (%). Also, it was not written in descending order of degrees.Learn more about Polynomials in Standard Form here:https://brainly.com/question/32213698

144 students enter a spelling bee, but only 1/6 of the group will make into the semi-final round, and only 2 /3 that group will make into the final round. How many students will enter the final round of the spelling bee?
Answer:
16 students
Step-by-step explanation:
144 students enter a spelling bee contest.
Step 1
For the semi final round we are told that only 1/6 of the group will make it into that round.
This is calculated as
1/6 × 144/students = 24 students.
This means that only 24 students would make it into the semi final rounds.
Step 2
We are also told in the question that only 2/3 of THAT group would make it into the final round.
" THAT" group been referred to in the question means the number students that made it to the semi final round
This is calculated as
2/3 of that group( the group that made it to the semi finals)
= 2/3 × 24 students
= 16 students.
Therefore, the number of students that will enter the final round of the spelling bee is 16 students.
To calculate the number of students who will make it to the final round of the spelling bee, we first determine the semi-finalists by multiplying the total students by 1/6, and then the number of finalists by multiplying the semi-finalists by 2/3, resulting in 16 students.
Explanation:To solve this problem, we first need to determine the number of students who will make it into the semi-final round. Since only 1/6 of the total students will make it to the semi-final round, we can calculate that by multiplying the total students (144) by 1/6, which results in 24 students.
Next, we need to calculate the number of students that will make it into the final round from the semi-final round. This means we need to multiply the semi-finalists (24) by 2/3, which results in 16.
Therefore, 16 students will make it into the final round of the spelling bee.

Step-by-step explanation:
Felipe takes a commuter train to get to work. He pays a one-time fee to store his bike at the train station. He pays a
monthly fee for train passes. The total cost c for Felipe to travel to work for m months is given by the equation
80m + 50. What do the numbers 80 and 50 represent?
Answer:
80 represents the monthly fees and 50 represents the fixed one-time fee to store the bike at the train station.
The number 80 represents the monthly train pass cost, while 50 represents the one-time bike storage fee. Multiply the monthly fee by the number of months and add the bike storage fee to get total cost c for m months.
The number 50 is the initial, one-time cost to store Felipe's bike at the train station. To calculate the total commuting cost c for Felipe for m months, you multiply the number of months m by the monthly train pass cost, and then add the one-time bike storage fee.
