Hernando ate 2/8 of a pizza for a dinner. he gave his 6 friends the rest of the pizza, and told them to share equally. To determine the fraction of the whole pizza that each of his friends received, Hernando performed the calculations below.
6/8 divided by 6= (6 divided by 6)/8= 1/8
he concluded that each person received 1/8 of the whole pizza. Are Hernando's calculations correct?

O yes they are correct. Hernando divided 6 by 6
O yes they are correct. Hernando divided 2/8 by 6
O No they are not correct. Hernando should have multiplied by 6, not divided by 6
O No, they are not correct. Hernando should have divided 8 by 6, not 6 by 6.

Answer:

-13

Step-by-step explanation:

Given that:

Average temperature for a period of 4 days = - 8

Average temperature for a 5 day period = - 9

Temperature on the 5th day:

(total temp for the 4 days + 5th day temperature) / 5 = - 9

Let 5th day temperature = x

Total temperature for the 4 days = 4 * - 8 = - 32

(-32 + x) / 5 = - 9

-32 + x = - 45

x = - 45 + 32

x = - 13

Step-by-step explanation:

i hopes this helps

Answer:

1/8x ... -1 would be the y intercept so 1/8x is the slope

Hello there, hope you are having a splendid day. :)

y=1/8x-1

This equation is written in slope-intercept form, which looks like so:

y=mx+b

Where m is the slope (1/8) and b is the y-intercept (-1).

Hope it helps. Ask me if you have any queries.

Answer:

4 times

Step-by-step explanation:

Given that the sum of all the numbers => 3+4+5+6+7+8+9+10 = 52

And we are to divide it into two sets such that the sum of set B is three times the number of sum of set A => Sum B = 3 * Sum A

Hence Total sum = Sum B + Sum A

Total sum ÷ 4 = 52 ÷ 4 = 13.

Since Sum B = (3 * Sum A) => (3 * 13 ) = 39

Therefore Sum B = 39 and Sum A = 13

To divide them into two sets

Sum A = (10, 3) = 13: Sum B = ( 4, 5, 6, 7, 8, 9) = 39

Sum A = (9, 4) = 13: Sum B = (3, 5, 6, 7, 8, 10) = 39

Sum A = (8, 5) = 13: Sum B = (3, 4, 6, 7, 9, 10) = 39

Sum A = (7, 6) = 13: Sum B = (3, 4, 5, 8, 9, 10) = 39

Hence, the correct answer is 4 times

Answer:

2(a) 30°

(b) 48,59°

(c) 31,4485°

(d) 33,005565°

Answer:

4 meters

Step-by-step explanation:

Let the height at which the top of the ladder is be represented by h. The sketch of the question forms a right angled triangle. So that applying the Pythagoras rule,

[tex]/hyp/^{2}[/tex] = [tex]/Adj 1/^{2}[/tex] + [tex]/Adj 2/^{2}[/tex]

[tex]5^{2}[/tex] = [tex]h^{2}[/tex] + [tex]3^{2}[/tex]

25 = [tex]h^{2}[/tex] + 9

[tex]h^{2}[/tex] = 25 - 9

   = 16

⇒ h = [tex]\sqrt{16}[/tex]

      = 4

Therefore, the height at which the top of ladder is placed is 4 meters.

Answer:

x = a³b + b²/ab + 1

Step-by-step explanation:

x = a² + b²/ab + 1

x = a² × (ab + 1) + b²/ab + 1

x = a³b + a² + b²/ab + 1

x = a³b + b²/ab + 1

Answer:

$69 is the total cost of the bill

Step-by-step explanation:

60(1.15)

60 is the cost of the bill, and the 1.15 is the added tax plus the previous $60.

Put 60(1.15) into a calculator and

$69

Answer:

x = 4.25 (A. 4.25)

Step-by-step explanation:

(For, 4x + 39) 4 times 4.25 = 17, then add 17 + 39, which gets you to 56.

( for 16x - 12) multiply 16 times 4.25 = 68. subtract 12 from 68 to equal 56.

Answer:

April took out a loan of $600 and paid it back with simple interest of $60 after 5 years. The formula to calculate interest is  given the principal  and the time   and the interest rate  is . For this problem we have to find the interest rate   given  . To archive that , we can just solve the equation making the interest rate the subject of the formula as shown below,

The interest rate is  or 0.02 as a decimal. The interest rate is 2% as a percentage.

Step-by-step explanation:

Answer:

2%

Step-by-step explanation:

Answer:

B

Step-by-step explanation:

Because there is 1000 people in total, the percentage of people in the school B with cellphones would be solved by finding 408/1000=.408. If you round .408 to the nearest hundredth, because the thousandth place is 8, it would round up to .41

Answer:

[tex]\huge\boxed{\text{(B)}\ 0.41}[/tex]

Step-by-step explanation:

This table will prove to be helpful to find the probability that a student has a cell phone and is from School B.

First off, we know that a total of 1000 students were interviewed, both from School A and from School B.

We also know that 479 of those 1000 were from School B (total on the right).

Looking further into School B, we can see that 408 students from school B have a cell phone.

Therefore, we can find the probability by finding 408 / 1000.

[tex]408 \div 1000 = 0.408 \approx 0.41[/tex]

Therefore, the probability that a randomly selected student is from School B and has a phone is 0.41, or 41%.

Hope this helped!

[tex]Let\ Abduls\ present\ age\ be\ x\\His\ Grandfather's\ present\ age\ = 4x\\\\Abdul's\ age\ before\ 10\ years=x-10\\His\ Grandfather's\ age\ before\ 10\ years =4x-10\\\\We\ are\ given\ that\ ,\\Abdul's\ Grandfather's\ age\ before\ 10\ years = 7 * Abdul's\ age\ before\ 10\ years\\Hence, \\4x-10=7(x-10)\\4x-10=7x-70\\-10+70=7x-4x\\60=3x\\x=20\\Hence,\\Abduls\ present\ age\ =20\\His\ grandfather's\ present\ age\ = 4*20=80[/tex]

Answer:

Abdul's age=20 y/o

Grandpa's age=80y/o

Step-by-step explanation:

let Abdul's age be 'x'

so, grandpa's age=4x

Grandpa's age 10 yrs ago= 4x-10

according to the question, grandpa's age 1o yrs ago=7(x-10)

so, 4x-10=7(x-10)

     4x-10=7x-70

by substituting,

     70-10=7x-3x

     60=3x

     60/3=x

      20y/o=x

so, 4x=20*4=80 y/o
