√10 • √8 =
A. 4√5 or
B. 3√2
Which one?

Answers

Answer 1

Answer:

A. ([tex]4\sqrt{5}[/tex])

Step-by-step explanation:

√10 • √8 = [tex]\sqrt{80}[/tex]  - They combine into one.

 [tex]\sqrt{80}[/tex]

 /     \

[tex]\sqrt{20}[/tex]   [tex]\sqrt{4}[/tex]

 [tex]\sqrt{4}[/tex] = 2

[tex]\sqrt{20}[/tex] = [tex]2\sqrt{5}[/tex]

2 * 2 = 4

[tex]4\sqrt{5}[/tex] is the answer.

Find the distance between thE two coordinates A(2,6),N(5, 10)

Answers

Using it's formula, the distance between the points A(2,6) and N(5,10) is of 5 units.

What is the distance between two points?

Suppose that we have two points, [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex]. The distance between them is given by:

[tex]D = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

For this problem, the points are A(2,6) and N(5,10), hence the distance is given by:

[tex]D = \sqrt{(5 - 2)^2+(10 - 6)^2}[/tex]

D = sqrt(3² + 4²)

D = sqrt(25)

D = 5.

The distance between the points A(2,6) and N(5,10) is of 5 units.

Answers

Answer:

[tex](j-5)(j+3)[/tex]

Step-by-step explanation:

[tex]j^2-2j-15=(j-5)(j+3)[/tex]

The age of John’s brother is j-5 and the age of John’s sister is j+3.

Given that, John is j years old. The product of his younger brother's and older sister's age is j²-2j-15.

What is an expression?

An expression is a combination of terms that are combined by using mathematical operations such as subtraction, addition, multiplication, and division.

The solution for j²-2j-15 is as follows

j²-2j-15

⇒ j²-5j+3j-15

⇒ j(j-5)+3(j-5)

⇒ (j-5)(j+3)

Therefore, the age of John’s brother is j-5 and the age of John’s sister is j+3.

Jon caught four fish that weighed a total of 264 pounds. The kingfish weighed twice as much as the
amberjack and the white marlin weighed twice as much as the kingfish. The weight of the tarpon was 5
times the weight of the amberjack.
How much did each fish weigh?

Answers

Answer:

Amber jack 22 pounds

Tarpon 110 pounds

King fish = 44 pounds

White Marlin = 88 pounds

Step-by-step explanation:

Let the weight of the amber jack be x pounds

Kingfish weighed twice as much = 2 * x = 2x pounds

White Marlin weighed 2 times kingfish

= 2x * 2 = 4x pounds

Tarpon weighs 5 times amber jack = 5 * x = 5x

Add all together to give 264

5x + 4x + 2x + x = 264

12x = 264

x = 264/12

x = 22 pounds

Hence ;

Amberjack weighs 22 pounds

Tarpon = 5 * 22 = 110 pounds

Kingfish = 2 * 22 = 44 pounds

White Marlin = 2 times king fish = 2 * 44 = 88 pounds

   Height = 6inches

    Area  = 21in²

Unknown:

b₂ = ?

Solution:

 Formula for finding the area of a trapezium;

         A = [tex]\frac{1}{2}[/tex][tex](b_{1} + b_{2} )[/tex] x h

     Input the parameters and solve for b₂;

What is the distance between two points ( p,q) and (x,y)?

The shortest distance (length of the straight line segment's length connecting both given points) between points ( p,q) and (x,y) is:

D = √[(x-p)² + (y-q)²]    units.

Given that Square ABCD has vertices; A(-4.5, 4), B(3.5, 4),C(3.5, -4), and D(-4.5, -4).

To find the distance from two of the vertices of the square. The distance formula is as follows;

√[(x-p)² + (y-q)²]  

A(-4.5, 4), B(3.5, 4),

D = √[(x-p)² + (y-q)²]  

D = √(3.5-(-4.5))² +(4 -(4))²

D = √(3.5-(-4.5))² +(4 -(4))²

D = √(64 + 0)

D = 8

Therefore, the side of the square is 8 units.

The area of the square = side x side

= 8 x 8

= 64 unit sq.

Answers

Answer:

27

Step-by-step explanation:

Given that:

Green shirt = 81 students

White shirt = 54 students

Orange shirt = 27 students

The largest number of student in each row : we need to obtain the greatest common factor for the three numbers.

Factors of :

81 : 1, 3, 9, 27, 81

54 : 1, 2, 3, 6, 9, 18, 27, 54

27: 1, 3, 9, 27

The greatest factor which is common in all three numbers is 27, hence, the largest number of student in each row should be 27

Step-by-step explanation:

We have that the proportional relationship between the number of gallons of milk (m) and the numbers of days (d) Erin drinks milk is:

Hence, the days that would take Erin to drink 1 gallon of milk is:

Therefore, it would take for Erin 8 days to drink 1 gallon of milk.

Read the text carefully, then answer the question located beneath:Time to "Bee" Wary, by Gordon WintersAfricanized honey bees were created in Brazil in 1957. Scientists mixed local bees with African ones to create a bee that would make more honey. They ended up with something much different. The new bees evolved in unexpected ways. They multiplied and migrated north. These Africanized honeybees are now known as killer bees for several scary but legitimate reasons.Killer bees are far more aggressive than their relatives. They have been known to attack in great numbers, even when there has been no direct threat on their hives. They have swarmed because of loud noises, dark clothing, bright jewelry, and even strong perfume. They will chase a person for more than a quarter of a mile and remain angered for up to 24 hours.Killer bees are also dangerous because of their sting. While most bees take up to 30 seconds to attack, killer bees sting in just 3 seconds. Their venom is no stronger than a regular bee's, but when one killer bee stings, others follow. With up to 80,000 members in a colony, victims are quickly overwhelmed. So many stings in such a short time can cause allergic reactions. Victims enter a state of shock, lose blood pressure, and in many cases, die.A final reason why "killer" has been added to their name is the unfortunate number of deaths they have caused. Experts estimate that the Africanized honeybee moves at a rate of about 200 miles each year. As the bees claim new territory, they claim new victims as well. More than 1000 people have been stung to death in South and Central America. There have been rising numbers of attacks in Mexico and a handful in the United States. Once a swarm sets sights on a victim, it is very difficult for the victim to escape. Once attacked, it is very difficult to survive.Thankfully, there has been no killer bee invasion as some once predicted. Although there is no need for panic, the threat of the killer bee is real and should be taken seriously. It is good practice to call a professional to remove beehives in your area. If you are stung multiple times by any insect, you should always seek medical attention. You may not be expert enough to tell the difference between a killer bee and a less dangerous one, so be smart. It is better to be safe than sorry.Which details relate to the main fact in the third paragraph? (5 points)Answers:Killer bees attack in great numbers. They swarm for many reasons.
