401 km 101 m – 34 km 153 m

Answers

Given :

An expression D = 401 km 101 m – 34 km 153 m.

To Find :

Value of D.

Solution :

We know, 1 km = 1000 m.

So, 401 km 101 m =( 401000 + 101 ) m = 401101 m.

Also, 34 km 153 m = ( 34000 + 153 ) m = 34153 m.

Now, D is given by :

D = 401101 - 34153 m

D = 366948 m

Now, D = 366948 m = 366 km 948 m.

Therefore, the difference is 366 km 948 m.

Hence, this is the required solution.

For the function g(x) = x – 2x^2, find g (–3) + 13

Answers

Answer:

g( - 3) + 13 = - 2

Step-by-step explanation:

g(x) = x - 2x²

To find g( - 3) + 13 substitute the value of x that's - 3 into g(x) and add 13 to it

We have

g( - 3) + 13 = - 3 - 2(-3)² + 13

= -- 3 - 2(9) + 13

= 3 - 18 + 13

We have the final answer as

g( - 3) + 13 = - 2

In the given figure, PQ=PR and QS is the bisector of angle PQR. If angle PQS=30°, find angle PSQ.
​

Answers

Answer:

90°

Step-by-step explanation:

PQ=PR ⇒

∠PQR = ∠PRQ

QS is the bisector of angle PQR ⇒

∠PQS= ∠RQS

If angle PQS=30°, find angle PSQ

∠PQS=30° ⇒

∠PQR = 2*∠PQS = 2*30° = 60°

As ∠PQR = 60°,

∠PRQ = 60° and ∠QPR = 60° as remaining angle

So,

∠PSQ = 180° - (∠QPR + ∠PQS) = 180° - 90° = 90°

What are the next two terms in the sequence?
5, 16, 27, 38 ...

Answers

Answer:

the next two terms are 49, 60

       

Answer:

49, 60

Step-by-step explanation:

There is a common difference between consecutive terms in the sequence.

16 - 5 = 27 - 16 = 38 - 27 = 11

Thus to obtain the next term, add 11 to the previous term, that is

38 + 11 = 49

49 + 11 = 60

Answers

for point slope form just plug in what is given so you have

m = -3
point (x₁, y₁): (5, -2)

y-(-2) = (-3)(x-(5))
y+2 = -3(x-5)

^for point slope form

for y-intercept form...just solve your point slope equation for y:

y+2 = -3(x-5)
y+2-2 = -3(x-5) -2
y = -3x+15 -2
y = -3x + 13

If m∠PTQ = 3y –10 and m∠QTR = y, find the value of y so that ∠PTR is a right angle

Answers

Answer:

y = 25

Step-by-step explanation:

Given that,

m∠PTQ = 3y –10 and m∠QTR = y

We need to find the value of y so that ∠PTR is a right angle.

For a right angle, one of the angle is 90 degrees. The sum of the angle of a triangle is equal to 180 degrees. So,

3y –10 + y + 90 = 180

Taking like terms together

3y+y = 180 -90 +10

4y = 100

y = 25

So, the value of y is 25.

Nick uses 1/4 cup of vinegar for every 1 cup of olive oil when making salad dressing.
Using this recipe, how much vinegar would he need to make salad dressing with 12 cups of olive oil?

Answers

Answer:

3 cups of vinegar

Step-by-step explanation:

∵ Nick uses the amount of vinegar for every 1 cup of olive oil = [tex]\frac{1}{4}[/tex] cup

∴ He will need the amount of vinegar for 12 cups of olive oil = [tex]\frac{1}{4}\times 12[/tex] cups

                                                                                                 = 3 cups

Therefore, Nick will need 3 cups of vinegar to make salad dressing.

What effect does decreasing the temperature of a room have on a lifespan of a battery?

Which variable is highlighted in red, bolded tex?  

a . Independent

b . Dependent

c . Control

d . None

But the answer to both the independent and dependent variables will be provided and explained in detail.

Answer:

Independent variable: decrease in temperature

Dependent variable: lifespan of battery

 Step-by-step explanation:

The independent variable in an experiment is defined as the variable that can be changed or manipulated in order to find an outcome while the dependent variable is defined as the variable that is influenced by the changes in the independent variable.

In the given example, a decrease in temperature  is the dependent variable as it is changing and the lifespan of battery  is the dependent variable as it is responding to the independent variable ?9decrease in temperature).

On a fine morning in June he went out alone to walk in the green woods. He was tired of the noise of the city, and he was glad to get away from it. So, as he walked among the trees, he often stopped to listen to the singing birds, or to look at the wild flowers that grew on every side. Now and then he stooped to pluck a violet, or a primrose, or a yellow buttercup. Soon his hands were full of pretty blossoms. After a while he came to a little meadow in the midst of the wood. Some children were playing there. They were running here and there, and gathering the cowslips that were blooming among the grass. It made the king glad to see the happy children, and hear their merry voices. He stood still for some time, and watched them as they played. Then he called them around him, and all sat down together in the pleasant shade. The children did not know who the strange gentleman was; but they liked his kind face and gentle manners. "Now, my little folks," said the king, "I want to ask you some questions, and the child who gives the best answer shall have a prize." Then he held up an orange so that all the children could see. "You know that we all live in the kingdom of Prussia," he said; "but tell me, to what kingdom does this orange belong?" The children were puzzled. They looked at one another, and sat very still for a little while. Then a brave, bright boy spoke up and said,-- "It belongs to the vegetable kingdom, sir." "Why so, my lad?" asked the king. "It is the fruit of a plant, and all plants belong to that kingdom," said the boy. The king was pleased. "You are quite right," he said; "and you shall have the orange for your prize." He tossed it gayly to the boy. "Catch it if you can!" he said. Then he took a yellow gold piece from his pocket, and held it up so that it glittered in the sunlight. "Now to what kingdom does this belong?" he asked. Another bright boy answered quickly, "To the mineral kingdom, sir! All metals belong to that kingdom." "That is a good answer," said the king. "The gold piece is your prize." The children were delighted. With eager faces they waited to hear what the stranger would say next. "I will ask you only one more question," said the king, "and it is an easy one." Then he stood up, and said, "Tell me, my little folks, to what kingdom do I belong?" The bright boys were puzzled now. Some thought of saying, "To the kingdom of Prussia." Some wanted to say, "To the animal kingdom." But they were a little afraid, and all kept still. At last a tiny blue-eyed child looked up into the king's smiling face, and said in her simple way,-- "I think to the kingdom of heaven." King Frederick William stooped down and lifted the little maiden in his arms. Tears were in his eyes as he kissed her, and said, "So be it, my child! So be it." The king's interaction with the children may best be described asA)lecturing.B)explaining.C)provocative.D)interrogating.
