What are lines and angles?

Straight lines with little depth or width are present. You will learn about a number of lines, including transversal, intersecting, and perpendicular lines.

A figure called an angle is one in which two rays originate from the same point. In this area, you could also encounter contrasting and related viewpoints.

Given that there are different lines crossing each other at different angles. The value of the different angles can be named as,

Rank the following in order from most precise to least precise.
1500 grams
8.43 inches
1580 meters
5.426 seconds

Answers

Answer:

1st most = 8.43 inches

2nd most = 5,426 Seconds

3rd most = 1580 meters

4th most = 1500 grams

Step-by-step explanation:

8.43 inches = 0.7025 feet is most precise as it rounded to 0.7 feet it wouldn't be precise enough.

5,426 Seconds =  01:30:26. hrs mins sec can be converted.

1580 meters = 1.58 km = 158000cm  hasn't been properly converted as zeros get lost.

A greeting card cost four dollars before tax. A customer has a 15% discount. Then the 5% sales tax is added. How much will the customer pay for the card?

Answers

Given:

Greeting card cost before tax = $4

Discount = 15%

Sales tax = 5%

To find:

How much will the customer pay for the card?

Solution:

It is given that the cost of the greeting card before tax is $4.

After 15% discount, the cost of the greeting card is:

Cost of card after discount [tex]=4-\dfrac{15}{100}\times {4}[/tex]

                                             [tex]=4-0.6[/tex]

                                             [tex]=3.4[/tex]

The cost of card after 5% sales tax is:

Cost of card after tax [tex]=3.4+\dfrac{5}{100}\times 3.4[/tex]

                                    [tex]=3.4+0.17[/tex]

                                    [tex]=3.57[/tex]

Therefore, the customer will pay $3.57 for the greeting card.

Last week, Russell bought 8 pizzas and 10 cakes for a total of $160.
Today, Russell bought 26 pizzas and 8 cakes for a total of $226.
Assuming neither item has changed in price, what is the cost of a pizza in dollars?

Answers

Answer:

$5

Step-by-step explanation:

Create a system of equations where p is the cost of a pizza and c is the cost of a cake

8p + 10c = 160

26p + 8c = 226

Solve by elimination by multiplying the top equation by -4, and the bottom equation by 5

-32p - 40c = -640

130p + 40c = 1130

Add these together:

98p = 490

p = 5

So, the cost of a pizza is $5

Ok I am fine I am now in

Answer:

A) (40 + 50) + (6 + 1) + (0.6 + 0.5) + (0.01 + 0.02)

Step-by-step explanation:

In this case, you are breaking each term down to it's non-zero digits, and adding them:

46.61 = 40 + 6 + 0.6 + 0.01

51.52 = 50 + 1 + 0.5 + 0.02

Note however, that the answer choices add each individual non-zero terms together:

(40 + 50) + (6 + 1) + (0.6 + 0.5) + (0.01 + 0.02), or A)

A) (40 + 50) + (6 + 1) + (0.6 + 0.5) + (0.01 + 0.02) is your answer.

The ratio sin 30° : tan 45º can be written in the form 1 : n.
Find the value of n.

Answers

Answer:

n = 2

Step-by-step explanation:

sin 30° = ½

tan 45° = 1

then

sin 30° : tan 45° = 1 : n

½ : 1 = 1 : n

n = 2

The value of n for the trigonometric expression will be n = 2

What is trigonometry?

The branch of mathematics that sets up a relationship between the sides and the angles of the right-angle triangle is termed trigonometry.

The trigonometric functions, also known as a circular, angle, or goniometric functions in mathematics, are real functions that link the angle of a right-angled triangle to the ratios of its two side lengths.

Given that the ratio sin 30°: tan 45º can be written in form 1: n. The value of n will be calculated as:-

sin 30° = ½

tan 45° = 1

Then,

sin 30° : tan 45° = 1 : n

½ : 1 = 1 : n

n = 2

The given possible roots have the form that we'd get by using the quadratic formula, so let's start with that.  Here the coefficients are {2, -6, 3}, and so the discriminant (b^2 - 4ac) is (-6)^2 - 4(2)(3), or 36 - 24 = 12.

Someone Pls solve both fast

Answers

Answer:

#1) x=38

#2) x=12

Step-by-step explanation:

For (1)

Since its a triangle we know that all 3 interior angles added up is gonna eqaul 180 degrees. So we already have 2 angles which are 21 and 17. You add those up and you’d get 38. Now since the final angles is unknown we can just make a simple equation of 38+x=180 since we know 2 angles and we need 1 more and a triangle is 180 degrees alli ddded up together. You’d get 142 for that angle. X is adjacent to that angle and they form a straight line so it also has to be 180. We got 1 side and so we subtract 180-142= 38. X will be 38.

For (2)

Since its 2 parallel lines cut by a transversal and we have two same side interior angles we know its gonna be supplementary Which means that both those angles added up will be 180. Now we have the two different angles so we add them up and solve for x. (10x+17)+(3x+7)= 180. Commbine like terms which will turn out to be 13x+24=180. Subtract 24 on both sides. 13x= 156. Solve for x by diving 13 on both sides which will lead to x= 12
