Step-by-step explanation:

The equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

y + 2 = - 2(x - 3) ← is in point- slope form

with slope m = - 2 → A

Hey! I'm confused on this question It's : 3/4 - 3/10​

Answers

Answer:

9/20

Step-by-step explanation:

I hope this helps :)

Answer:

9/20

Step-by-step explanation:

In order to subtract fractions you need to find the least common denominator.  Since the LCD is 20 (4 times 5 or 10 times 2) you need to multiply each fraction by 1 to get the denominators the same.

3/4 times 5/5 = 15/20

3/10 times 2/2 = 6/20

now you can subtract!

15/20 - 6/20 = 9/20

you can not simplify this, so your final answer is 9/20

(Also pls make me brainliest im trying to level up)

Answer:

192$ (sale price)

Step-by-step explanation:

First we have to find 20% of 240

240×20/100         We multiply 240 by 20/100 because a percent is always  over 100 (as a fraction)

(240×20/100=48)     Now that we know 20% of 240 we have to subtract

240-48=192

192$ is the sale price

Lines m and n are parallel. The measure of angle 6 is 55°.
What is the measure of angle 1?




35°


55°


125°


155°

Answers

Answer:155

Step-by-step explanation:

because they are parallel lines. If the angles differed even by 1°, eventually the lines would meet, therefore they would not be parallel.

Answer:

Firstly angle 6 and 2 are equal because of corresponding angles

so 6 = 2

Now angle 1 + 2 = 180 ( linear pair)

angle 1 = 180 - 55

1 = 125

Which ratio represents the cotangent of angle B in the right triangle below?

A. 5/3
B. 3/5
C. 3/4
D. 4/3

Answers

Answer:

C. 3/4

Step-by-step explanation:

Using the SOH CAH TOA identity;

tan theta = opposite/adjacent

From the diagram

Opposite = x

Adjacent = 12

tan <B  = x/12

Since cot <B = 1/tan <B

cot <B = 12/x

Get x using pythagoras theorem

x² = 20²-12²

x² = 400 -144

x² = 256

x = 16

Hence cot <B = 12/16

cot <B =3/4

Bryan has quarters and nickels in his piggy bank. He has three times as many nickels as he has quarters. If the total value of the coins is $12, find the number of nickels in the piggy bank.

Answers

Answer:

90

Step-by-step explanation:

Quarters , q = 25 cent

Nickel, n = 5 cent

3 times as many nickels as quarters;

n = 3q

Total value of coins = $12

n + q = $12

0.05n + 0.25q = 12

0.05(3q) + 0.25q = 12

0.15q + 0.25q = 12

0.40q = 12

q = 12 / 0.40

q = 30

n = 3q

n = 3(30)

n = 90

90 nickels

What are the coordinates of point S"? (negative three-halves, nine-halves) (negative nine-halves, fifteen-halves) (nine-halves, negative three-halves) (negative fifteen-halves, 0)

Answers

Answer:

[tex]S=(\frac{9}{2},-\frac{3}{2})[/tex]

Step-by-step explanation:

The missing details are:

[tex]T= (0,4)[/tex]

[tex]M = (\frac{9}{4}, \frac{5}{4})[/tex] --- Midpoint of ST

Required

Determine the coordinates of S

To do this, we apply the mid-point formula:

[tex]M(x,y) = \frac{1}{2}(x_1+x_2,y_1+y_2)[/tex]

Where

[tex]M(x,y) = (\frac{9}{4}, \frac{5}{4})[/tex]

[tex]T(x_1,y_1) - (0,4)[/tex]

The equation becomes:

[tex]M(x,y) = \frac{1}{2}(x_1+x_2,y_1+y_2)[/tex]

[tex](\frac{9}{4},\frac{5}{4}) = \frac{1}{2}(0+x_2,4+y_2)[/tex]

[tex](\frac{9}{4},\frac{5}{4}) = \frac{1}{2}(x_2,4+y_2)[/tex]

Multiply through by 2

[tex]2*(\frac{9}{4},\frac{5}{4}) = 2*\frac{1}{2}(x_2,4+y_2)[/tex]

[tex](\frac{9}{2},\frac{5}{2}) = (x_2,4+y_2)[/tex]

By comparison:

[tex]x_2 = \frac{9}{2}[/tex]

[tex]4 + y_2 =\frac{5}{2}[/tex]

[tex]y_2 =\frac{5}{2}-4[/tex]

[tex]y_2 =\frac{5-8}{2}[/tex]

[tex]y_2 =-\frac{3}{2}[/tex]

Hence, the coordinates of S is:

[tex]S=(\frac{9}{2},-\frac{3}{2})[/tex]

This question is incomplete

Complete Question

If the measurement of a central angle is 5pi/6, find the length of its intercepted arc in a circle with a radius of 15 inches

a 33.4 inches

b. 35.6 inches

C. 37.5 inches

d. 39.3 inches

Answer:

d. 39.3 inches

Step-by-step explanation:

We are to find the Arc length of the circle

To solve the above question, the formula is given as:

Arc length = Central angle × radius

From the above Question, we are given:

Central angle = 5pi/6 = 5π/6

Radius = 15 inches

Hence,

Arc length = 5π/6 × 15 inches

Arc length = 235.61944901923448/ 6

Arc length = 39.26990817 inches

Approximately , the Arc length

= 39.3 inches.

A chess club with 45 members is electing a new president. Bob received 18 votes. What percentage of the club members voted for Bob?​

Answers

Given:

A chess club with 45 members is electing a new president.

Bob received 18 votes.

To find:

The percentage of the club members who voted for Bob.

Solution:

We have,

Total number of members = 45

Votes received by bob = 18

Now, the percentage of the club members who voted for Bob is

[tex]\%=\dfrac{\text{Number of members voted for bob}}{\text{Total members}}\times 100[/tex]

[tex]\%=\dfrac{18}{45}\times 100[/tex]

[tex]\%=\dfrac{2}{5}\times 100[/tex]

[tex]\%=\dfrac{200}{5}[/tex]

[tex]\%=40[/tex]

Therefore, 40% of the club members voted for Bob.

Children dreamed of traveling through space. Adults looked to the moon with a sense of national pride. Those days couldand shouldreturn again. it is not hard to find arguments against space travel. It costs money. Its dangerous. We have enough problems on our own planet. If the same Americans search their hearts, however, the results are different. Deep within us, we all have similar desires. Space exploration fulfills all these desires. From the time we are small children we long to know what is in the next room, down the street, or in the next town. We are nomads, wanting to explore. We are detectives, trying to solve a mystery. We are students of life, seeking answers. The space program gives us a chance to be all those things and more. Even if we dont travel ourselves, the excitement of new discoveries would again feed our thirst for something new. In the early days of space travel, America had a goal. We wanted to reach space safely and quickly. The country responded spectacularly. Teamwork and creativity reached all-time highs. Students delved deeper into science and math hoping to contribute. Heroes stepped up to bravely accept challenges. We were attempting the impossible and determined to succeed. Think of the amazing things Americans would accomplish if that inspiration returned. Exploring space reminds us how small and fragile our planet truly is. It encourages collaboration with other countries which helps cultural differences disappear. It can reveal the effects of abusing natural resources. Looking at our Earth from a great distance gives us a unique view of our world and the effect we have upon it. Exploration of our solar system should continue not for science or power or money, but for the benefit of mankind. It gives us an outlet for our curiosity. It provides inspiration for our souls. It offers a perspective to help understand our place in the universe. The benefits are as vast as space itself. Article 2: The Sky Has No LimitsThe state of NASAs space program has been the subject of much speculation in recent years. Debates have raged among members of Congress, business owners, and the general public. the president has expressed his thoughts on numerous occasions as well. The conversations seem to boil down to one question: Do the benefits of space travel outweigh the cost? A logical look at the question makes the answer quite apparent. NASAs space program is worth preserving at any cost. Put simply, NASA creates jobs. Jobs, in return, help the economy. A single space project can employ hundreds of workers from high level, top security jobs to lower level, yet important role players. Scientists are assigned to solve problems. Engineers are contracted to build prototypes. Truckers are hired to transport materials. Large corporations are paid for contributions, earning profits so they may hire more employeesThe work of NASA also pays huge dividends for the environment. Studying Earth from space provides keen insight into many areas. Scientists monitor the ozone layer. They track the effects of global warming. They study patterns of dangerous storms. They test the possibility of space colonies. All of these activities offer hope to our increasingly overcrowded planet The work of NASA often leads to advances in technology. Solving the mysteries of space creates solutions that help elsewhere. The Jaws of Life save victims in car accidents. The technology came from NASA research. The artificial heart did, as well. The list goes on. Architects, athletes, and autoworkers have benefited from space-related discoveries. NASA has enhanced everything from shoes to food. You likely come into contact with something improved by NASA nearly every day. It is impossible to list all the benefits of a thriving space program.
