How many different four-digit numbers can be formed with the numbers 7; 4; 5; 1; 2; 9; and 8?

Answers

Answer 1
Two answers are possible.
One is with the repetition of digits.
The other is without repetition of digits.
ANSWER 1: With Repetition
Numbers: 1,2,4,5,7,8
There are 4 digits __ __ __ __
1st digit can be filled by any of the 6 numbers.
Similarly 2nd, 3rd and 4th digits.
Hence each digit will have 6 possibilities.
Therefore no.of 4 digit numbers that can be formed are 6 x 6 x 6 x 6 = 1296
ANSWER 2: Without Repetition
4 digits __ __ __ __
Now the first digit can be filled by any of the six numbers. Therefore there are 6 possibilities
The second digit will have only 5 possibilities as one of the numbers gets used up by the 1st digit.
Similarly the 3rd and 4th digits will have 4 and 3 possibilities respectively.
Therefore no.of 4 digit numbers that can be formed are 6 x 5 x 4 x 3 = 360

6. Raymond purchases concert tickets online
for $43.50. There is a 3% processing fee.
What is the total cost of the tickets? Round
to the nearest cent. (Example 3)

Answers

Answer:

$44.81

Step-by-step explanation:

Multiplying $43.50 by 1 yields the base price of the ticket (price of one ticket).

Multiplying $43.50 by 0.03 yields the tax on this amount.

Multiplying $43.50 by (1 + 0.03) yields the total unit cost of the tickets:

(1.03)($43.50) = $44.81 (which has been rounded up to the nearest cent)

If Will buys 1 kilogram of African rice and 2 kilograms of basmati rice, how much will he spend? brown rice $3.03/kg $3.59/kg sticky rice African rice $1.69/kg Bhutanese red rice white rice $3.42/kg $3.26/kg $3.05/kg basmati rice​

Answers

Answer:

Step-by-step explanation:

Sorry, because of lack of punctuation and organization, I cannot determine with any confidence the price per kilo of each of the rices.

He will spend the price of one kg of African rice plus twice the price of Basmati rice.

IF

African rice = $1.69/kg

and

Basmati rice = $3.05/kg

THEN

Cost = 1.69 + 2(3.05) = $7.79

Find x to find the measure of the remote interior angle

Answers

Answer:

x = 88

Step-by-step explanation:

Theorem:

The measure of an exterior angle of a triangle is equal to the sum of the measures of its remote interior angles.

x + 46 = 134

x + 46 - 46 = 134 - 46

x = 88

Which expression is the factorization of x2 + 10x + 21?

(x + 3)(x + 7)
(x + 4)(x + 6)
(x + 6)(x + 15)
(x + 7)(x + 14)

Answers

(X+3) (X+7) is the answer

Factorisation of x² + 10x + 21

x² + 10x + 21

Here, let's first multiply the extreme values,i.e. 1*21 = 21. So, we need to get such a number that adds 21 and as we can see that 10x is the middle value of this sum. Hence, 7 and 3 is suitable as while adding it makes 10 and multiplying we get 21

x² + (7 + 3)x + 21

x² + 7x + 3x + 21

Now, lets segregate it into two groups. 1st group is x² + 7x and the other pair is 3x + 21 after which lets factorise them

x(x + 7) + 3(x + 7)

(x + 3)(x + 7)

So, we get the first option as correct which is (x + 3)(x + 7)


in Triangle ABC. the measure of the largest angle is 32 less than 3 times the smallest angle. The measure of the middle angle is & more
than half the measure of the largest angle. What is the measure of the middle angle?

Answers

Answer:

I hope this helps! Please mark brainliest if the answer is correct!

Step-by-step explanation:

Let "x" be the measure of the smallest angle.

Then the largest angle is "3x - 32" and the middle angle is "8 +  1/2(3x - 32)".

There are 180 degrees in a triangle so adding the three angles gives us 180:

(x) + (3x - 32) + (8 + 1/2(3x - 32)) = 180

x + 3x + (3/2)x - 32 + 8 - 16 = 180

2x/2 + 6x/2 + 3x/2 - 40 = 180

11x/2 = 220

11x = 220(2)

11x = 440

x = 40

So the smallest angle is 40°

The largest angle is 3•40 - 32 = 120 - 32 = 88°

The middle angle is 8 + 1/2(88) = 8 + 44 = 52°

Answer:

Step-by-step explanation:

∠ABC + ∠CBD = 90°

x + 7 + 2x + 14 = 90°

x + 2x   + 7 + 14 = 90

3x + 21 = 90

Subtract 21 from both sides

3x = 90 - 21

3x = 69

Divide both sides by 3

x = 69/3

x = 23

∠ABC = x + 7

Sarah made 2 3/4 cup of lemonade she drank 1 and 1/2 cups for lunch how much lemonade does she have left ​

Answers

Answer:

1 1/4 cup

Step-by-step explanation:

Make the mixed fractions regular fractions by multiplying the outside number by the denominator and then adding it to the numerator. For example

2 3/4

2 * 4 = 8 + 3 = 11

2 3/4 = 11/4

You should get 3/2 for how much she drank.

Now make sure your denominators are the same. Multiply both the numerator and denominator of the amount she drank by two to get 6/4

Then subtract the fractions.

11/4 - 6/4 = 5/4

Now make that into a mixed fraction.

Answers

Answer:

x =  (√2)

Step-by-step explanation:

Note that this is a 45-45-90 triangle, and that

cos 45 = adjacent side / hypotenuse.  We want to find the value of x, which happens to be the adjacent side.

Recall (or look up) that cos 45 = 1/(√2).  Thus:

1 / (√2) = x / 2.  Solve for x by multiplying both sides by 2:

2 / (√2) = x

We want the answer as a fraction with ratinal denominator.  To obtain this, multiply both numerator and denominator by  (√2):

x =  (√2)

If you play a standard bass guitar, you will notice that it only has four strings. E, A, D, G is the standard tuning for a four-string bass (the same as the four lowest strings on the guitar but one octave lower). Fourths are used to tune the bass strings. A 4-string will probably suffice for most styles.

C) Pharaohs were considered gods among men, and their chief role was to lead the people in a religious manner. D) Pharaohs were not considered gods among men, rather they were considered to be wise kings who care little for riches.Passage:The time is coming on now for the King to go in state to the great temple at Karnak to offer sacrifice, and as we go up to the palace to see him come forth in all his glory, let me tell you a little about him and the kind of life he leads. Pharaoh, of course, is not his real name; it is not even his official title; it is just a word which is used to describe a person who is so great that people scarcely venture to call him by his proper name. Just as the Turks nowadays speak of the "Sublime Porte," when they mean the Sultan and his Government, so the Egyptians speak of "Per-o," or Pharaoh, as we call it, which really signifies "Great House," when they mean the King. For the King of Egypt is a very great man indeed; in fact, his people look upon him, and he looks upon himself, as something more than a man. There are many gods in Egypt; but the god whom the people know best, and to whom they pay the most reverence, is their King. Ever since there have been Kings in the country, and that is a very long time now, the reigning monarch has been looked upon as a kind of god manifest in the flesh. He calls himself "Son of the Sun"; in the temples you will see pictures of his childhood, where great goddesses dandle the young god upon their knees (Plate 2). Divine honours are paid, and sacrifices offered to him; and when he dies, and goes to join his brother-gods in heaven, a great temple rises to his memory, and hosts of priests are employed in his worship. There is just one distinction made between him and the other gods. Amen at Thebes, Ptah at Memphis, and all the rest of the crowd of divinities, are called "the great gods." Pharaoh takes a different title. He is called "the good god." At present "the good god" is Ramses II. Of course, that is only one part of his name; for, like all the other Pharaohs, he has a list of titles that would fill a page. His subjects in Thebes have not seen very much of him for a long time, for there has been so much to do away in Syria, that he has built another capital at Tanis, which the Hebrews call Zoan, down between the Delta and the eastern frontier, and spends most of his time there. People who have been down the river tell us great wonders about the beauty of the new town, its great temple, and the huge statue of the King, 90 feet high, which stands before the temple gate. But Thebes is still the centre of the nation's life, and now, when it is growing almost certain that there will be another war with those vile Hittites in the North of Syria, he has come up to the great city to take counsel with his brother-god, Amen, and to make arrangements for gathering his army. The royal palace is in a constant bustle, with envoys coming and going, and counsellors and generals continually passing in and out with reports and orders. Outside, the palace is not so very imposing. The Egyptians built their temples to last for ever; but the palaces of their Kings were meant to serve only for a short time. The new King might not care for the old King's home, and so each Pharaoh builds his house according to his own taste, of light materials. It will serve his turn, and his successor may build another for himself how to differentiate instruction in academically diverse classrooms
