Richard gets a bonus of 30% of £130 Connor gets a bonus of £40 work out the difference between the bonus Richard gets and the bonus Connor gets

Answers

Answer:

Please check the explanation.

Step-by-step explanation:

Given that Richard gets a bonus of 30% of £130.

Thus,

Richard's bonus = 30% of 130

                           = 30/100 × 130

                           = 39

Thus, Richard gets £39.

Given that Connor gets a bonus of £40.

The difference between the bonus Richard gets and the bonus Connor gets.

Difference = Connor Bonus - Richard Bonus

                 = £40 - £39

                 = £1

It means Connor gets  £1 more than what Richard gets.

Therefore, the difference is: £1

ASAP. Triangle ABC has angle measures as shown. complete sentences
(a) What is the value of x? Complete sentence. Show your work.
(b) What is the measure of each angle? Do the 3 angles add to 180 degrees? Show your work

Answers

In a triangle, the three angles ALWAYS add up to 180°

x + (6x + 10) + (x + 2) = 180

8x + 12 = 180

8x = 168

x = 21

To calculate the measure of each angle, substitute x in:

Angle A: 21

Angle B: 6(21)+10

Angle C: 21 + 2

Do the angles add up to 180 degrees? Just add the answer for A B and C and see if the sum is 180. It should be 180, if it isn't something is wrong with the calculation.

what is 153.87 divided by 23

Answers

the answer will be 6.69

The result of dividing 153.87 by 23 is approximately 6.6847826087.

Given that we need to determine that what is 153.87 divided by 23,

To justify this answer, we can perform the division calculation:

  6.6847826087

--------------

23 | 153.87

    138

    -----

     158

     138

     -----

      208

      207

      -----

        10

The division is performed by dividing 23 into 153.87. We start by dividing 23 into 153, which gives us 6 as the whole number part of the quotient. We then subtract 138 (6 multiplied by 23) from 153, which leaves us with a remainder of 15.

To obtain a decimal approximation, we bring down the decimal point from the dividend (153.87) and continue the division process.

We add a zero after the decimal point in the dividend and divide again. This time, 23 goes into 158 (the new dividend) 6 times, giving us a partial quotient of 0.6.

The remainder is 158 minus 138 (6 multiplied by 23), which equals 20.

We bring down another zero and continue dividing.

23 goes into 208 (the new dividend) 9 times, resulting in a partial quotient of 0.69. The remainder is 208 minus 207 (9 multiplied by 23), which equals 1.

At this point, we can either stop or continue dividing to obtain more decimal places.

Therefore, the result of dividing 153.87 by 23 is approximately 6.6847826087.

5 hours after noon, darmian is 17 miles closer to the stadium than paisley

Step-by-step explanation:

At noon, Damian is 383 miles away from the stadium and paisley is 315 miles away from the stadium.

Now, we are told that damians speed is 59 mph while paisley's speed is 42 mph.

At t hours after noon, their distance covered will be;

Damian; D = 59t

Paisley; P = 42t

This is because distance = speed × time

Now, 5 hours after noon, their respective distance covered will be;

D(5) = 59 × 5 = 295 miles

P(5) = 42 × 5 = 210 miles

This means that;

distance of Damian from the stadium is; 383 - 295 = 88 miles

Distance of paisley from the stadium is;

315 - 210 = 105 miles

Difference in their distances to the stadium = 105 - 88 = 17 miles

Thus, 5 hours after noon, darmian is 17 miles closer to the stadium than paisley

What does it mean for a point to be a solution to a linear equation?

For example, if I say, "(2,5) is a solution to the equation (y=2x+3)," how could you check my claim?

Answers

Answer:

In your equation y=2x+3 and you used 2 [from your point (2,5) ] as the value of x, then y=2(2)+3=7.

now if you plotted this, that point would be (2,7), not (2,5).

So (2,5) is not the solution.

(2, 5) is not a solution of the linear equation [tex]y = 2\cdot x + 3[/tex].

Let be linear equation [tex]y = 2\cdot x + 3[/tex], if we know that [tex](x,y) = (2, 5)[/tex] and we need to check is [tex]2\cdot x + 3 = 5[/tex] by algebraic means, that is, we solve for [tex]x[/tex]:

[tex]2\cdot x + 3 = 5[/tex]

[tex]2\cdot x = 2[/tex]

[tex]x = 1[/tex]

Hence, we conclude that (2, 5) is not a solution of the linear equation [tex]y = 2\cdot x + 3[/tex].

Is the given value a solution to the equation? 4(n) - 3 = -2(n) + 9 n=2

Answer:

Yes!

The solution to the equation is n = 2

Step-by-step explanation:

Given the equation

[tex]4\left(n\right)-3=-2\left(n\right)+9[/tex]

remove the parentheses

[tex]4n-3=-2n+9[/tex]

Add 3 to both sides

[tex]4n-3+3=-2n+9+3[/tex]

Simplify

[tex]4n=-2n+12[/tex]

Add 2n to both sides

[tex]4n+2n=-2n+12+2n[/tex]

Simplify

[tex]6n=12[/tex]

Divide both sides by 6

[tex]\frac{6n}{6}=\frac{12}{6}[/tex]

Simplify

[tex]n=2[/tex]

Therefore, the value of n = 2.

Hence,

Yes!

The solution to the equation is n = 2

She applied and was accepted. Now it was summer break, and she was in Uganda. She was staying with Mr. Omara, a teacher at the school, and his family. When Mr. Omara showed her the school, she could not believe how many students were packed into the classroom. Students were seated on benches behind long tables and on the floor. She guessed there were ninety to a hundred students in one classroom! Ms. Perry worked with a small group of students as they practiced writing and speaking English. From her conversations with them, she learned about their lives. Ritah, Joseph, and Winnie got up at 5 a.m. and walked half a mile each way to collect water from the well before they walked to school. At night, they did their homework by candlelight. During her month in Africa, Ms. Perry learned that not only did schools need pens and paper, but books. Five students in a class shared one textbook. Mr. Omara explained that textbooks had to match the curriculum and be bought in Uganda. However, many storybooks in English were needed for reading practice. When Ms. Perry returned to Minneapolis, her class of 25 students looked small. She told them about the school she had visited. After she finished, Jackson said, The students need supplies and books, so we should collect these and send them to the school.Thats a great idea for a project, Victoria said. How can we get started? Ms. Perry said, Remember, we will need money for shipping expenses. If everyone lists their ideas for the project, we will talk about your ideas on Friday. On Friday, everyone was eager to share ideas. Eva had found a Web site that listed books needed in Uganda. Ms. Perry suggested they focus on fiction, or storybooks about made-up people and events. It would help students practice their skills in reading English. Logan pointed out that drop-off boxes for books could be placed in the front hall of the school and in the cafeteria. Everyone would see them there during lunchtime. Molly suggested publicity, saying they could make posters to get their information to the public. Ians idea was to collect books from families and neighbors and sell them in the shopping mall one weekend to make money. Molly drew a poster decorated with colorful books. It said, Bring your books to Parkside School for our book drive. From November 1 through November 15, we are collecting books to send to a school in Uganda. We need picture books and especially the books listed below. She printed the titles of the recommended books.At the bottom, it said, We are selling used books for adult readers to pay for our shipping charges. Stop by Vernon Mall on November 13 or 14.
