Step-by-step explanation:

In this figure, |v| represents the absolute value to 0. For example, |-3| would be 3 because it is 3 spaces from 0.

|10| - 3 × |-2| +5

10 - 3 * 2 + 5

Find the value of each variable so that the quadrilateral is a parallelogram.
(3y)
(8x-6)°
42°
y =

Answers

so if it is a parallelogram then the angles will add up to 360° and the angles opposite one another will be equal

we can start by finding y

3y = 42
divide by 3
y = 14

now we know that both angles are equal to 42° so to find the missing angles we must double 42 and subtract is from 360 then divide by 2 to find the individual angle

42 x 2 = 84
360 - 84= 276
276/2 = 138

the angle of 8x - 6 = 138

now we solve for x by first adding 6
8x = 144
then divide by 8
x = 18

so y = 14 and x = 18

What is the difference between plotting (2, 3) and (3, 2) on a coordinate plane? Explain ​

Answers

When plotting coordinates, the first number is called your X axis, while the second number is your Y. Since the X axis goes left and right, and the Y axis goes up and down, plotting (2,3) would be a point closer to the bottom of the graph and somewhere in the right. (3,2) would be higher up and less far right.Ma

Answer:

When plotting coordinates, the first variety is referred to as your X axis, whilst the second number is your Y. Since the X axis goes left and right, and the Y axis goes up and down, plotting (2,3) would be a factor nearer to the backside of the plan and someplace in the right. (3,2) would be higher up and less far right.

today reza ate 20 grapes which is 400% as many grapes as he ate yesterday. explain how to use equal ratios to find the number of grapes reza ate yesterday

Answers

Answer:

Write 400% as the ratio 400/100. To find an equivalent ratio, you know that 400 divided by 20 is 20, so 100 divided by 20 will give you the answer. 100 ÷ 20 = 5. Reza ate 5 grapes yesterday.

Brainliest please!

Answer:

What you must do for this case is to extract the relationship of the grapes that were eaten yesterday among the grapes that were eaten today.

To do it, let:

x: number of grapes that Reza ate yesterday

(x / 20) = (100/400).

Clearing x we have:

x = (100/400) * (20) = 5

answer

the number of grapes Reza ate yesterday was 5

find the exact value of tan30⁰ × cos30⁰
give your answer in its simplest form​

Answers

ANSWER:

tan(30⁰)=√3/3

cos(30⁰)=√3/2

switch sides:

sin(x) /√3/2 =√3/3

multiply both sides by 3:

3·sin(x) /√3/2 =3·√3/3

simplify:

2√3 sin (x) =√3

divide both sides by 2√3:

2√3 sin (x) / 2√3 = √3 / 2√3

simplify:

sin (x)= 1/2

An engineer designs a 65-foot cellular telephone tower. Find the angle of elevation to the top of the tower at a point on level ground 40 feet from its base. (Round your answer to one decimal place.)

Answers

Answer:

the angle of elevation is  58.4°

Step-by-step explanation:

Given the data in the question and as illustrated in the image below;

let ∅ be the angle of elevation;

Opposite (AC) = 65 ft  

Adjacent (CB) = 40 ft  

we know that; from SOH CAH TOA

TOA

tan∅ = Opposite / Adjacent

so;

tan∅ = 65 / 40

tan∅ = 1.625

∅ = tan⁻¹ ( 1.625 )

∅ = 58.3924 ≈ 58.4°

Therefore, the angle of elevation is  58.4°

3. 96 students are enrolled in the Dance Program at Castillero. Of those students, 54 are eighth-graders. The remaining students are 6th or 7th graders. What percentage of the students are not eighth graders?

Answers

Answer:

1) new price of the clock is $14.4

2) Kyra scored 70% marks

3) 43.75% students are not eighth graders

Step-by-step explanation:

1. A store manager marked up the price of a $12 clock by 20%. What is the new price of the clock?

Price of Clock = $12

Mark up = 20%

We need to find new price of clock.

The price of  clock can be found by finding 20% of 12 and then adding that amount in original price.

So, finding 20% of 12

[tex]20\% of 12 \\=\frac{20}{100}\times 12\\=2.4[/tex]

So 20% of 12 is 2.4

Now finding new price:

New Price = Actual Price + Mark up

New Price = 12 + 2.4

New Price = 14.4

So, new price of the clock is $14.4

2. On a math quiz, Kyra answered 7 of 10 questions correctly. Express her quiz score as a percent.

Total questions = 10

Correct answers = 7

We need to express her quiz score as percent

It can be found using formula: [tex]Percent Score = \frac{Obtained\:Marks}{Total\:Marks}\times 100\%\\[/tex]

Putting values and finding percentage

[tex]Percentage = \frac{Obtained\:Marks}{Total\:Marks}\times 100\%\\\\Percentage = \frac{7}{10}\times 100\%\\Percentage = 70\%[/tex]

So, Kyra scored 70% marks

3. 96 students are enrolled in the Dance Program at Castillero. Of those students, 54 are eighth-graders. The remaining students are 6th or 7th graders. What percentage of the students are not eighth graders?

Total Students = 96

Number of eighth-graders students = 54

Remaining students = 96 - 54 = 42

So, 42 students are 6th or 7th graders

We need to find percentage of the students are not eighth graders.

[tex]\frac{42}{96}\times 100\%\\=43.75\%[/tex]

So, 43.75% students are not eighth graders
