1. At a specific time of day, a flagpole has a shadow 40 ft long, at the same time of day
Jose who is 6 ft tall has a shadow of 8ft long. Find the height of the flagpole to the
nearest tenth of a foot if needed.

Answers

Answer: x= 30 ft tall

Explanation: you know the lengths of both shadows so therefore you put 40 over 8 (like a fraction) and then you need to find out height of the flagpole, but you do know the height of Jose so therefore you put x over 6 right next to 40 over 8. Then you cross multiply 40 x 6= 240 and then you change the x into 8. So NOW you then divide your answer from 40 x 6 (240) by 8 and then you get your answer which is X = 30 ft tall

How do you simplify 4ab + 13bc

Answers

Answer:

you cant

Step-by-step explanation:

its already simplified from the way its written

b(4a + 13c) is the simplified form of the expression 4ab + 13bc

To simplify the expression 4ab + 13bc, we can factor out the common term "b" from both terms:

4ab + 13bc = b(4a + 13c)

By factoring out the common term "b", we obtain the simplified form b(4a + 13c).

This represents the original expression in a more concise and factored form.

Hence, the simplified form of the expression 4ab + 13bc is b(4a + 13c) by taking the common term b

Answers

Answer: The correct symbol is '<'.

Step-by-step explanation:

Given: In triangle GHJ

[tex]m\angle H=85^{\circ}[/tex] and [tex]m\angle G=60^{\circ}[/tex]

Here angle H is opposite to side JG and angle G is opposite to side HJ

We know that,

The side opposite to the greater angle of a triangle is greater.

Since [tex]m\angle H> m\angle G[/tex]

Then, JG > HJ

Hence, HJ < JG

64sq in x 36 tiles = 2,304 square inches

if there are 36 total tiles on the table, that means there are 6 on each side.

If each side meaures 8, then one side of the table is 48, and since the tikes are square, the other side of the table will be the same. 48 x 48=2,304

Factor the expression using the GCF 7+14

Answers

Answer:

We found the factors and prime factorization of 7 and 14. The biggest common factor number is the GCF number. So the greatest common factor 7 and 14 is 7.

Step-by-step explanation:

The value of the Expression 7+ 14 using the GCF is 21.

What is Greatest Common Factor?

The largest factor that splits both numbers is said to be the greatest common factor. List the prime factors of each integer before calculating the greatest common factor. One 2 and one 3 are shared by those aged 18 and 24. The GCF of 18 and 24 is 2 * 3 = 6, which we multiply to obtain.

Given:

We have to add 7 + 14

Factorise the terms separately

7 = 7 x 1

14 = 7 x 2

So, the Greatest Common Factor is 7.

Thus, 7+ 14 = 7(1+ 2) = 7 x 3= 21

To begin, open Electric Field Hockey.Directions:On the control bar, make sure that the Puck is Positive and the Field boxes are checked. Also, make sure that the Practice option is selected.Your aim is to score goals by manipulating the black puck (test charge) into the blue-colored bracket (goal) on the right. Think smart and place positive source charges (red) and negative source charges (blue) in such a way that the black puck moves into the goal.Note that when you place a red, positive source charge in the hockey field, a red arrow appears on the black puck (test charge) showing the force the positive charge exerts on the puck. Similarly, when you place a blue, negative source charge in the hockey field, a blue arrow appears on the black puck (test charge) showing the force the negative charge exerts on the puck.Question 1Part APlace a red charge on the hockey field and click Play. In which direction do electric field lines point? In which direction does the black puck move? What conclusion do you draw from this movement?Part BClick Reset and then click Clear. Now, place a blue charge in the hockey field and click Play. In which direction do electric field lines point? In which direction does the black puck move? What conclusion do you draw from this movement?Part CManipulate the mass of the puck by dragging the mass bar to the right to increase the mass and to the left to decrease it. What changes do you see in the speed of the puck? Which principle works behind this change?Part DIn the same situation, what do you observe about the relationship between the speed of the black puck and its distance from the blue charge?Question 2You can make the puck travel in complex ways by placing a set of charges around on the field. So, heres your game challenge: Arrange sources charge around to propel the puck from its starting position into the goal. Thats pretty easy for a straight shot; you just put a negative charge behind the goal. But what if there are barriers along the way? This is a real test of your physical understanding, including Newtons laws of motion and electrostatic forces. Games on!Part AOn the control bar, check the Trace and Field boxes. The game has three Difficulty levels. Start with Difficulty level one and arrange source charges to get the puck into the goal. Once youve made a score at any level, increase the Difficulty level.
