Answer:

$260 each

Step-by-step explanation:

Combined, Mr. Chen as 5 children. 2800-1500 = 1300. 1300/5 = $260 per child.

You have to plug in the values into the equation.

Since a=6, all the a's in the equation would be replaced by 6 and same goes for the b.

^ means exponent btw

= -[2(6)^2 -6- (5(6)^2-3(3)) -4(6)^2 +2(3)]

Calculate/ simplify

= -[2(36)-6 - (5(36) -9)-4(36)+6]

Multiply all the things in parenthesis

= -[72-6-(171)-144+6]

Add/subtract

= -[-243]

Negative times negative becomes positive therefore, the answer becomes 243

Answer:

52 < 55

So 13 gal < 55 quarts

Answer:

  3√10 +√26 ≈ 14.6 units

Step-by-step explanation:

In order to find the perimeter of the figure, we need to determine the lengths of its sides. A plot of the points on a graph reveals that three sides are a length that is the hypotenuse of a right triangle with legs 3 units and 1 unit. Those lengths are ...

  c² = a² +b²

  c = √(3² +1²) = √10

The remaining longer leg is the hypotenuse of a right triangle with legs 5 units and 1 unit. Its length is ...

  c = √(5² +1²) = √26

__

The perimeter of the figure is the sum of its side lengths. The sum of the lengths of the three short sides and the long side is ...

  3√10 +√26 ≈ 14.59 . . . units

The perimeter of the quadrilateral is about 14.6 units.

Answer:

c = 0.50(0.48)(1525)

Step-by-step explanation:

If 52% of the students are female, then

100% - 52% = 48% of the students are male

48% = 48/100 = 0.48

To find the number of students who are male:

⇒ total number of students x 0.48 = 0.48 x 1525

Half = 50% = 50/100 = 0.50

⇒ half of the male students = 0.50 x 0.48 x 1525

Solution:  c = 0.50(0.48)(1525)

Answer:

Pythagorean Theorem

Step-by-step explanation:

a² + b² = c²

The sum of the square of the hypotenuse is equal to the sum of the squares of the sides of the right triangle.

When you have a 90-degree angle in a triangle, the Law of Cosines simplifies to the Pythagorean theorem: c² = a² + b².

When you have a 90-degree angle in a triangle, it means that the triangle is a right triangle.

In a right triangle, one of the angles is exactly 90 degrees, and the side opposite to this right angle is called the hypotenuse.

The Pythagorean theorem relates the lengths of the sides of a right triangle and is a special case of the Law of Cosines.

The Law of Cosines is given by:

c² = a² + b² - 2abcos(C)

Where:

c is the length of the side opposite angle C.

a and b are the lengths of the other two sides.

C is the angle opposite side c.

Now, when you have a right triangle and C is the right angle (90 degrees), the cosine of the right angle becomes zero.

This is because the cosine of 90 degrees is 0.

Therefore, the Law of Cosines simplifies to:

c² = a² + b² - 2abcos(90°)

c² = a² + b²

Hence, c² = a² + b² is the well-known formula for the Pythagorean theorem, which relates the squares of the lengths of the two shorter sides (legs) of a right triangle to the square of the length of the hypotenuse.

Answer:The solution is in the attached file

Step-by-step explanation:

Solution:

Note that:

Use the formula to obtain the equation of the line.

The equation of the line is y = 4x + 9.

Answer:

13.56$

To write an equation, we need to think about what this is asking us. It's asking us to take a number and increase the total % to be 113% of the original number. This looks something like

[tex]y = 1.13x[/tex]

Where y is amount with a tip and x is amount before a tip. To calculate for 12 dollars, we plug 12 into x and it comes out as 13.56 dollars

The area of the triangle is 16m³n units³.

The length of the time that randy read is 45 minutes.

Time is known to be an element that is often measured or that is measurable.

From the image attached, Randy started reading at 4:10 and Randy finished reading at 4:55.

We therefore need to subtract:

4:55 - 4:10 = 45 minutes

So, Randy is said to read  for 45 minutes.

Let us solve the problem step by step.

here we have rolled two dice. So total no. of possible outcomes will be 6^2=36. These are (1,1),(1,2),(1,3),(1,4),(1,5),(1,6),(2,1),(2,2),(2,3),(2,4),(2,5),(2,6),(3,1),(3,2),(3,3),(3,4),(3,5),(3,6),(4,1),(4,2),(4,3),(4,4),(4,5),(4,6),(5,1),(5,2),(5,3),(5,4),(5,5),(5,6),(6,1),(6,2),(6,3),(6,4),(6,5),(6,6).

Now, among these cases the cases where the sum is seven for (1,6), (2,5), (3,4), (4,3), (5,2), (6,1) i.e. there are 6 cases.

Now, it is time to calculate the probability.

The required probability is,

p = (No. of cases favorable for the event)/(Total no. of cases)

=6/36 = 1/6

If two six-sided dice are rolled and the two dice are equal. The probability that one die is a 3 will be 6.

It is defined as the ratio of the number of favorable outcomes to the total number of outcomes, in other words, the probability is the number that shows the happening of the event.

It is given that, two six-sided dice are rolled and the two dice equal 7.

If two dice are rolled. The total no. of possible outcomes will be,

= 6²

=36

The total outcomes are,

(1,1),(1,2),(1,3),(1,4),(1,5),(1,6),(2,1),(2,2),(2,3),(2,4),(2,5),(2,6),(3,1),(3,2),(3,3),(3,4),(3,5),(3,6),(4,1),(4,2),(4,3),(4,4),(4,5),(4,6),(5,1),(5,2),(5,3),(5,4),(5,5),(5,6),(6,1),(6,2),(6,3),(6,4),(6,5),(6,6).

If the desired outcome is their sum which is 7. All the possible cases are 6,

(1,6), (2,5), (3,4), (4,3), (5,2), (6,1)

The required probability is,

p(sum=7) = (No. of cases favorable for the event)/(Total no. of cases)

p(sum=7)=6/36

p(sum=7)= 1/6

Thus, if two six-sided dice are rolled and the two dice are equal. The probability that one die is a 3 will be 6.

Answer:

13/30

Step-by-step explanation:

The expected score that Joe can obtain provided the probability of the left-out questions being correct as per the given situation is 90.8.

Points secured by Joe by answering correctly = 12*6 = 72

Probability is the conversion of possibilities or occurrences in numbers.

Now, the probability of a correct guess in the questions in which Joe eliminated 2 choices = 1/3

So, the possible marks of Joe in those 4 questions = 1/3*4*6=8

Probability of correct guess in remaining 9 random guesses= 1/5

So, the possible marks that Joe can score in those 9 random guesses = 1/5*9*6 = 10.8

Therefore, the expected score of Joe = 72+8+10.8 = 90.8
