solve the system of equation

Answers

Answer 1

Answer:

x = 12, y = 0

Step-by-step explanation:

Use elimination.

24y = 0

y = 0

Then plug back into the second equation.

2x + 9(0) = 24

2x = 24

x = 12

Plug back into the first equation to check.

A right circular cylinder has a base radius of 56 mm and a height of 128 mm. What is its volume in cubic centimeters? Round the answer to the nearest hundredth. use 3.14 for π

Answers

Answer:

V = 1261 mm2

Step-by-step explanation:

Hello

V = Pi*(r^2)*h

V = Pi*([56]^2)*(128=

V = 1261 mm2

Best regards

Final answer:

The volume of the right circular cylinder is approximately 1,261,852.32 cubic centimeters (rounded to the nearest hundredth).

Explanation:

To find the volume of a right circular cylinder, we use the formula:

V = πr2h

where V is the volume, π is the value of pi (approximately 3.14), r is the base radius, and h is the height. Plugging in the given values:

V = 3.14 * 562 * 128

V ≈ 3.14 * 3136 * 128

V ≈ 3.14 * 401,408

V ≈ 1,261,852.32

Therefore, the volume of the right circular cylinder is approximately 1,261,852.32 cubic centimeters (rounded to the nearest hundredth).

What is x^5 Y^6 expressed in simplified form?

Answers

Answer:

Nothing further can be done to this.

Step-by-step explanation:

There is nothing further that can be done with this equation.

Final answer:

The expression x^5 Y^6 doesn't simplify further as the bases differ. It means that 'x' is multiplied by itself five times, and 'y' is multiplied by itself six times.

Explanation:

The expression x^5 Y^6 is already in simplest form. Expressed in plain English, this represents 'x' raised to the power of 5, multiplied by 'y' raised to the power of 6. The exponents here denote that we are multiplying 'x' and 'y' by themselves for a specific number of times. For example, 'x' is multiplied by itself five times, and 'y' is multiplied by itself six times, as represented by this expression.

I want to let you know that the exponents are not to be combined in any way because the bases (x and y) are different. In other words, x^5 and Y^6 remain separated in expression. They cannot be simplified further.

also, i apologize if this answer is wrong. i havent done this in a while and im not 100% sure on my work accuracy.

Answer:

3.

Step-by-step explanation:

Count the number of 'x' symbols are above each number.

There are:

two 1/6 pieces (total of 2/6)

two 1/3 pieces (total 2/3)

three 1/2 pieces (total 3/2 aka 1 and 1/2)

four 2/3 pieces (total 8/3 aka 2 and 2/3)

one 5/6 piece (total 5/6)

Since we know that halves and thirds can be divided into sixths, we'll have to set all the denominators into sixths by multiplying. The numbers are in the same order as above.

2/6 * 1/1 = 2/6

2/3 * 2/2 = 4/6

1 and 1/2 * 3/3 = 1 and 3/6 (only multiply the fraction if it is a fraction and a whole)

2 and 2/3 * 2/2 = 2 and 4/6

5/6 * 1/1 = 5/6

Next we'll add together all the WHOLE numbers.

1 + 2 = 3

Now add all the fractions. Remember, only add the numerators, the denominator stays the same in adding.

2/6 + 4/6 + 3/6 + 4/6 + 5/6 = 18/6

Simplify the fraction.

18/6 = 3.

Answers

Answer:

x = 1.56  or x = -2.56

Step-by-step explanation:

From the equation;

x2 +x − 4 = 0

a = 1 , b = 1, and c = -4

x = (-b ± √(b² -4ac))/2a

  = (-1 ± √(1²- 4×1×-4))/2

  = ( -1 ± √(17)/2

A large round pizza has a diameter of 14 inches what is the approximate area of the pizza

Answers

The area of a circle is found using the equation A = πr^2

r is the radius which is 1/2 the diameter

r = 14 /2 = 7

Area = π7^2

Area = 49π

Using 3.14 for π

Area = 49 x 3.14

Area = 153.86 square inches.  Round the answer as needed.

Final answer:

To find the area of a large round pizza with a diameter of 14 inches, use the formula A = (7 inches), which is half of the diameter, to find the area, resulting in approximately 153.86 square inches.

Explanation:

The area of a circle is calculated using the formula A = case and simplify the expression since the radius has only two significant figures. Utilizing an approximation for pi ( case 3.14), the area can be calculated as follows:

A = (3.14) (7 in) (7 in) approximately 3.14 (49 in²) approximately 153.86 in². Therefore, the approximate area of the pizza is 153.86 square inches.

a fair die is cast four times. Calculate the probability of obtaining exactly two 6's

Answers

Answer:

25/216 or 0.1157

Step-by-step explanation:

The probability of getting a 6 is 1/6.  

The probability of not getting a 6 is 5/6

We roll a die 4 times and want 2 sixes, and 2 not sixes.  

We want a combination of 2 sixes from 4 rolls, so we can use the binomial formula to solve this...

(4C2)(1/6)²(5/6)² = 6(1/36)(25/36) = (1/6)(25/36) = 25/216 = 0.1157

The long hand way of solving this is to list the 6 ways we can roll our desired result along with their probabilities...

We could get

6, 6, not 6, not 6      (1/6)(1/6)(5/6)(5/6) = 25/1296

6, not 6, 6, not 6       (1/6)(5/6)(1/6)(5/6) = 25/1296

6, not 6, not 6, 6       (1/6)(5/6)(5/6)(1/6) = 25/1296

not 6, not 6, 6, 6       (5/6)(5/6)(1/6)(1/6) = 25/1296

not 6, 6, not 6, 6       (5/6)(1/6)(5/6)(1/6) = 25/1296

not 6, 6, 6 not 6        (5/6)(1/6)(1/6)(5/6) = 25/1296

There are 6 different way this can happen, each having a probability of 25/196.  We add up the probabilities, getting 150/1296, which reduces to

A store has apples on sale for $28.00 for 8 pounds. If an apple is approximately 5 ounces, how many apples can you buy for $168.00? Complete the explanation.

The cost per pound of the apples on sale is $
.
You can buy
pounds of apples for $168.00.
Since 1 pound = 16 ounces, so there are about
apples in each pound.
You can buy approximately
apples for $168.00.

Answers

Find the number of apples in 8 pounds:

8 pounds x 16 ounces per pound = 128 ounces.

Divide total cost by cost for 8 pounds:

168 / 28 = 6

Multiply 6 by 128 ounces:

128 x 6 = 768 total ounces for $168.

Now divide total ounces by 5 ounces per apple:

768 / 5 = 153.6, round up to 154 apples.

Answer:

For $168 you could buy approximately 48 pounds of apples.

The answer to this is A and E, W and X, C and P

A is -7

E is 7

These are opposite

W is -5

X is 5

These are opposite

B is -3

C is 3

These are opposite

The answer is A

Answer:

A. A and E, W and X, C and P

Step-by-step explanation:

The opposite of any number (let's call it "x") is a number which, if added to x, results in 0.

Typically is -x, because x + (-x) = x - x = 0

Knowing these, let's see the values that are marked:

A = -7

W = -5

C = -3

B = 1

P = 3

X = 5  

E = 7

The opposite of 7 is -7, so A and E are opposites.

The oposite of 5 is -5, so X and W are opposites

The opposite of 3 is -3, so P and C are opposites.

The opposite of 1 is -1, but -1 is not marked.

The correct answer is the first one.
