Bethany Can Mow Her Lamily's Lawn In 4 Hours. Her Brother Coin Can Mow The Lawn Into HoursWhich Equation

Answers

Answer 1

Answer:

1/x = 1/4 + 1/3

Step-by-step explanation:

In 4 hours Bethany did the whole fraction 1 of the house.

In 1 hour he would do 1/4 of it.

In 3 hours Colin did the whole fraction 1 of the house.

In 1 hour he would do 1/3 of it.

In 1 hour they would both do (1/4 + 1/3)

If it takes both of them x hours to finish 1 whole fraction of the house.

In 1 hour they will both do 1/x

That means that:

1/x = 1/4 + 1/3

That is the equation. x can be solved for.

Which scales are equivalent to 1 inch to 1 foot? Select all that apply. Group of answer choices 1 to 12 (1/12) to 1 100 to 0.12 5 to 60 36 to 3 9 to 108

Answers

Answer:

1 to 125 to 609 to 108

Step-by-step explanation:

There are 12 inches in one foot so the equivalent ones are:

1 to 12

This shows that there are 12 inches in one foot so is equivalent.

5 to 60

5/60 = 1/12

This is equivalent because it shows that 12 inches are required to make a foot.

9 to 108

9/108 = 1/12

This is also equivalent for the same reasons as above.

(TV ) ⃗ bisects ∠STU,m∠STV=(1/4 x+8)°,
and m∠UTV=(x+2)°.Find m∠STU.

Answers

Answer:

m∠STU = 20 °

Step-by-step explanation:

Since the line bisects the angle, we have that the two bisected angles are equal

Thus, mathematically;

x + 2 = x/4 + 8

Multiply through by 4

4x + 8 = x + 32

4x-x = 32-8

3x = 24

x = 24/3

x = 8

So to find the value of the original angle, we input 8 into each of the bisected angles and add together

mathematically, that will be ;

10 + 10 = 20

No because you would need to multiply the denominators by the denominators and the numerators by the numerators to get 1/81. Priya is adding the numerators.

Answers

Answer:

6

Step-by-step explanation:

Since the degree of the angle is 45, we know that the triangle is isosceles. That means that the sides of the triangle, not including the hypotenuse, has a length of 3√2.

Using the Pythagorean theorem, which is a^2 + b^2 = c^2, we have (3√2)^2 + (3√2)^2 = c^2.

Note: c is the hypotenuse of the triangle.

18 + 18 = c^2

= 36 = c^2

Therefore, c = 6.

what is the formula for finding missing angles of a triangle

Answers

Answer:

Now that you are certain all triangles have interior angles adding to 180° , you can quickly calculate the missing measurement. You can do this one of two ways: Subtract the two known angles from 180° . Plug the two angles into the formula and use algebra: a + b + c = 180°


What is the slope of the linear equation y=x+10
a. Slope=m=10
b. Slope=m=1
c. Slope=m=5
d. Slope=m=11

Answers

Answer:

slope = 1

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = x + 10 ← is in slope- intercept form

with slope m = 1

The answer is A because slope=m=10 is equal to a line

The Necklace She was one of those pretty and charming girls born, as though fate had blundered over her, into a family of artisans. She had no marriage portion, no expectations, no means of getting known, understood, loved, and wedded by a man of wealth and distinction; and she let herself be married off to a little clerk in the Ministry of Education. Her tastes were simple because she had never been able to afford any other, but she was as unhappy as though she had married beneath her; for women have no caste or class, their beauty, grace, and charm serving them for birth or family, their natural delicacy, their instinctive elegance, their nimbleness of wit, are their only mark of rank, and put the slum girl on a level with the highest lady in the land. She suffered endlessly, feeling herself born for every delicacy and luxury. She suffered from the poorness of her house, from its mean walls, worn chairs, and ugly curtains. All these things, of which other women of her class would not even have been aware, tormented and insulted her. The sight of the little Breton girl who came to do the work in her little house aroused heart-broken regrets and hopeless dreams in her mind. She imagined silent antechambers, heavy with Oriental tapestries, lit by torches in lofty bronze sockets, with two tall footmen in knee-breeches sleeping in large arm-chairs, overcome by the heavy warmth of the stove. She imagined vast saloons hung with antique silks, exquisite pieces of furniture supporting priceless ornaments, and small, charming, perfumed rooms, created just for little parties of intimate friends, men who were famous and sought after, whose homage roused every other woman's envious longings.When she sat down for dinner at the round table covered with a three-days-old cloth, opposite her husband, who took the cover off the soup-tureen, exclaiming delightedly: "Aha! Scotch broth! What could be better?" she imagined delicate meals, gleaming silver, tapestries peopling the walls with folk of a past age and strange birds in faery forests; she imagined delicate food served in marvelous dishes, murmured gallantries, listened to with an inscrutable smile as one trifled with the rosy flesh of trout or wings of asparagus chicken.She had no clothes, no jewels, nothing. And these were the only things she loved; she felt that she was made for them. She had longed so eagerly to charm, to be desired, to be wildly attractive and sought after.She had a rich friend, an old school friend whom she refused to visit, because she suffered so keenly when she returned home. She would weep whole days, with grief, regret, despair, and misery.Read each of the excerpts below from The Necklace. Most of them provide textual evidence for a theme related to the main character's belief that having more money would make her happy. Which excerpt is NOT related to this theme.They walked down towards the Seine, desperate and shivering. At last they found on the quay one of those old night-prowling carriages which are only to be seen in Paris after dark, as though they were ashamed of their shabbiness in the daylight.One evening her husband came home with an exultant air, holding a large envelope in his hand. "Here's something for you," he said. Swiftly she tore the paper and drew out a printed card on which were these words: "The Minister of Education and Madame Ramponneau request the pleasure of the company of Monsieur and Madame Loisel at the Ministry on the evening of Monday, January the 18th.""I'm utterly miserable at not having any jewels, not a single stone, to wear," she replied. "I shall look absolutely no one. I would almost rather not go to the party." "Wear flowers," he said. "They're very smart at this time of the year. For ten francs you could get two or three gorgeous roses." She was not convinced.She suffered endlessly, feeling herself born for every delicacy and luxury.
