4. 1 1/18

5. 1/4

6. 3 1/6

7. 1

Step-by-step explanation:

i will use the last one as an example, first reduce, so you would find the common denominator, in this case its 6, so you simplify 6/30 to 1/5. then you have 4/5+1/5, so since u have the same denominator, you can add the two numerators above the common denominator, so it would look like 4+1/5. then add the numbers. so you are left with 5/5 which in other words is 1. i hope this helps!

This is referred to a polygon which has three edges and vertices with its longest side being the hypotenuse.

The angle facing the largest side(AB) is always the largest which in this case is angle C, the medium side is side BC which has a length of 16 with the angle facing it as A which is why it is the second largest.

Answers

Answer:

1.05

Step-by-step explanation:

To start, you need to know how long the shelving is, so you would multiply 0.3*3 since there are three pieces of wood. After you do that, you need to find out exactly how much space is from the shelving to the wall, so multiply 0.05*2 since there are two sides of the shelf. Add it all together for a total of 1.05

If there are 4 ships at a port and the first one leaves and comes back every three weeks, the second one every nine weeks, the third one every 12 weeks, and the fourth every 24 weeks when will they all be in the port at the same time/when will they be there all at the same week

Answers

Answer: After 72 weeks they will be in the port at the same time.

Step-by-step explanation:

Given, Total ships = 4

The first one leaves and comes back every 3 weeks, the second one every 9 weeks, the third one every 12 weeks, and the fourth every 24 weeks .

So, the number of weeks they will take to  be in  the port at the same time = L.C.M. (3, 9, 12 , 24)   (L.C.M. = least common multiple)

Since, 9= 3 x 3

12 = 2 x2 x 3

24 = 2 x 2x 2 x3

then, L.C.M. (3, 9, 12 , 24)= 2 x 2x 2 x 3 x3 =72

Hence after 72 weeks they will be in the port at the same time.

Sanjay consulted three electricians about upgrading the wiring in his home. Each electrician uses a linear formula that incorporates a flat base fee and an hourly rate to determine the cost of service. Those formulas are shown in the table.

Repair Cost Formulas
Electrician
Cost in y dollars for an x-hour service
1
y = 25 x + 30
2
y = 30 x + 25
3
y = 25 x + 20

Which statement is best supported by the table?
Each electrician charges a different hourly rate.
Each electrician charges a different base fee.
All three electricians charge the same hourly rate.
All three electricians charge the same base fee.

Answers

Answer: B: each electrician charges a different base fee

Step-by-step explanation:

Answer:

b.Each electrician charges a different base fee:

Explanation:

Each of the equations has two parts:

1- base fee that is independent of any variable (this would be the number that has no variable next to it)

2- an hourly rate depending on the number of hours x (this would be the number that has an x next to it)

For the first electrician:

y = 25x + 30

base fee = $30

hourly rate = $25

For the second electrician:

y = 30x + 25

base fee = $25

hourly rate = $30

For the third electrician:

y = 25x + 20

base fee = $20

hourly rate = $25

Now, let's check the choices:

a.Each electrician charges a different hourly rate:

This is incorrect as electricians 1 and 3 charge the same hourly rate ($25)

b.Each electrician charges a different base fee:

This is correct as all three base fees are different ($30, $20 and $25)

c.All three electricians charge the same hourly rate:

This is incorrect as electrician 2 has a different hourly rate

d. All three electricians charge the same base fee:

This is incorrect as the base fees for the three electricians are different ($30, $25 and $20)

4. Write the modal class of the following frequency distribution:
Class interval

Frequency..
33
38
65
52
19
48​

Answers

The modal class, or mode class, is the class that has the highest frequency. Visually on a bar graph or histogram, it is the bar that is the tallest.

In this case, the highest frequency is 65 which corresponds to the class 30-40. The third frequency is the highest, so the third class is the modal class.

Answer: The interval 30-40 is the modal class

You are flying your dragon kite. It is connected to 34 yards of string. The kite is directly above the edge of a pond. The edge of the pond is 29 yards from where the kite is tied to the ground. How high is the kite above the edge of the pond? Round your answer to the nearest tenth.

Answers

Answer:

18 yards

Step-by-step explanation:

To find the height of the kite we need to consider the problem as a right triangle and use the Pythagorean theorem to solve it:

[tex] c^{2} = a^{2} + b^{2} [/tex]

Where:

c: is the length of the hypotenuse

a and b: are the length of the sides of the triangle

We have that the length of one side is 29 yards and the length of the hypotenuse is 34 yards, so we need to find the other side (which represents the height) as follows:

[tex] a = \sqrt{c^{2} - b^{2}} = \sqrt{(34)^{2} - (29)^{2}} = 18 [/tex]                          

Therefore, the height of the kite is 18 yards.

I hope it helps you!
