Answer:

52°

Step-by-step explanation:

If it is a right triangle, one interior angle is 90°, and we are also given the interior angle of 38°. The sum of any triangles interior angles will always be 180°.

90 + 38 = 128

180 - 128 = 52

The third angle is 52°

I have 2 questions. Please help! I will mark the Brainliest for the best answer(s)

1. Jane, Fay, and Henry had a total of $90. After Jane gave $12 to Henry and Fay gave $2 to Jane, all three of them had the same amount of money. How much money did each of them have in the beginning?
Jane has $__
Fay has $__
Henry has $__

2. The sum of three consecutive numbers is 723. Find the numbers.

The answer that is worth the Brainliest has all the answers to my questions, and is correct.

Answers

Answer:

1.   J=20, f= 28, H=42

2. 240 + 241 + 242 = 723

Step-by-step explanation:

J= 30- 12= 18+2= 20

F= 30-2=28

H=30+12=42

2.

240 + 241 + 242 = 723

1. Jane has $40 to begin with
Fay has $32 to begin with
Henry has $18 to begin with

They all end with the same amount which must be 30.

40-12=28.- Jane 18+12=30- Henry
32-2=30-Fay. 28+2=30

2. 240+241+242= 723

a number x divided by 8 is less than -2

Answers

Answer:  x/ 8 < -2           and x< -16

Step-by-step explanation:

A numer x is divided by 8  is the same as   x/ 8   and x/8 has to be the less than  -2  so it will be    x/8 < -2  

x/8 < -2   TO solve the inequality, multiply 8 on both sides  to get

x < -16

The solution of expression is,

⇒ x < - 16

We have to given that,

An algebraic expression is,

''a number x divided by 8 is less than -2''

We can write as,

⇒ x / 8 < - 2

Solve for x,

⇒ x/8 < - 2

Multiply by 8;

⇒ x < - 2×8

⇒ x < - 16

Therefore, The solution of expression is,

⇒ x < - 16

If x-y=6 and x^2+y^2=24, find x^3-y^3.

Answers

Answer:

162.06

Step-by-step explanation:

sorry i'm not the best an explaining but i'm confident in my answer.

the first thing to do is get rid of the ² in x²+y²=24, we do this by √24 which ≅4.90 (i rounded to the hundreth place)

then we have this

x-y=6

x+y=4.90

I am using the elmination method. To do that you need to get two letters to have the same coefficient (in 4x 4 is the coefficient) with oposite signs (one possitive one negitive)

In our equation here we see that the same coefficient is 0, and there is oposite signs for y. Therefore we can add the two equations and get

2x=10.9 (the y cancels out)

now we have a simple equation and all that is left is to solve it

10.9/2=5.45

x=5.45

Now we need to find y we do that by pluging the x value into one of the equations I choose the first one becasue its easiest.

(5.45)-y=6  

y= - .55

now that we have both x and y plug them into the final equation (5.45)³-(-.55)³= 161.89-(-.17) =162.06

Therefore x³-y³≅162.06!

the quotient of a number x and 3 is at most 4
an inequality is ?
the solution is ?

Answers

Answer:  The inequality is   x/3 [tex]\leq[/tex] 4   and   x [tex]\leq[/tex] 12

Step-by-step explanation:

The quotient of x and 3 is the same as x/3  and the at most sign is less than or  equal to. x/3 has to be  less than or equal to  4 which can be represented by the inequality,

x /3 ≤ 4            Solve for x by multiplying both sides by 3.

x ≤ 12

To transmit information on the internet, large files are broken into packets of smaller sizes. Each packet has 1,500 bytes of information. An equation relating packets to bytes of information is given by b=1,500p where p represents the number of packets and b represents the number of bytes of information.

1. How many packets would be needed to transmit 30,000 bytes of information?
2. How much information could be transmitted in 30,000 packets?
3. Each byte contains 8 bits of information. Write an equation to represent the relationship between the number of packets and the number of bits.

Answers

Answer:

45,000,000 information could be transmitted in 30,000 packets

Explaination:

b=1500p

p= 30,000

so,

b= 1500 x 30000 = 45,000,000

Answer:

1- 20 packets for this one you have to divide 30,000 by 1,500

2- 45,000,000 bytes for this one you have to multiply 1,500 by 30,000

3- so if each byte is 8 bits of information and 1,500 bytes equal one packet than each packet equals 187.5 bits of information and if you have 30,000 packets than there will be 3,750 bits of information the equation is the number of bytes in a packet divided by the number of bits of information in a byte which is 1,500/8 = 187.5 and the amount of packets you have you divide it by 8 because it is the number of packets divided by the number of bits of information
