Answer:

$0.30 per ear of corn, $0.24 per apple, $0.62 per tomato

Step-by-step explanation:

As 6 ears of corn cost $1.80, 180 cents divided by 6 equals 30 cents per ear.

As 12 apples cost $2.88, 288 cents divided by 12 equals 24 cents per apple.

As 5 tomatoes cost $3.10, 310 divided by 5 equals 62 cents per tomato.

Hope the explanations help!

There are $0.30 per ear of corn, $0.24 per apple, and $0.62 per tomato. which are determined by the division operation.

In mathematics, divides left-hand operands into right-hand operands in the division operation. The primary purpose of the division is to generate equal groupings or to determine how many people are in each category after a fair distribution.

For example 4/2 = 2

As 6 ears of corn cost $1.80,

cost $1.80 divided by 6

The cost per ear = $0.30

As 12 apples cost $2.88,

cost $2.88 divided by 12

The cost per apple = $0.24

As 5 tomatoes cost $3.10,

cost $3.10 divided by 5

The cost per tomato = $0.62

Hence, there are $0.30 per ear of corn, $0.24 per apple, and $0.62 per tomato.

simplify this equation into 4 x ((-2)/ 3).

Answer:

Option B

Step-by-step explanation:

Option B would be the right answer because instead of 8 being divided by 10 it should be 10 divided by 8.

Answer:

Four siblings have a dog walking business. The table shows the hours worked by each sibling. Each sibling earns $25.50 per hour and the total number of hours worked is represented by 10h+15 , where h represents the number of hours Michael worked.

Martin 2.5h+3

Emilio 4(h−2)

Michael h

Mario 31

The algebraic expression is the combination of variable and constants with some mathematical operation between them. The Earning of the four siblings are $357, $244.8, $112.2 and  $790.5 respectively.

An algebraic expression can be obtained by doing mathematical operations on the variable and constant terms.

The variable part of an algebraic expression can never be added or subtracted from the constant part.

Given that,

The earning of the siblings per hour is $25.50.

Total number of hours worked is 10h + 15.

As per the problem the value of h can be found by equating the total number of hours to the sum of hours worked by each sibling as given in the table as follows,

2.5h + 3 + 4(h - 2) + h + 31 = 10h + 15

⇒  2.5h + 3 + 4h - 8 + h + 31 = 10h + 15

⇒  7.5h + 26 = 10h + 15

⇒  2.5h = 11

⇒  h = 11 / 2.5

⇒  h = 4.4

Thus, the earning of each sibling can be calculated by substituting h = 4.4 in their working hour and multiplying it by $25.50 as follows,

Earning of Martin is given as,

(2.5 × 4.4 + 3) × $25.50 = $357

Earning of Emilio is given as,

4(4.4 − 2) × $25.50 = $244.8

Earning of Michael is given as,

4.4 × $25.5 = $112.2

Earning of Mario is given as,

31 × $25.50 = $790.5

Hence, the earnings of the four siblings are as Martin :  $357, Emilio : $244.8, Michael : $112.2 and Mario : $790.5.

Answer:

15 is the short answer

Step-by-step explanation:

Solution for 0.5 is what percent of 7.5:

0.5:7.5*100 =

(0.5*100):7.5 =

50:7.5 = 6.6666666666667

Now we have: 0.5 is what percent of 7.5 = 6.6666666666667

Question: 0.5 is what percent of 7.5?

Percentage solution with steps:

Step 1: We make the assumption that 7.5 is 100% since it is our output value.

Step 2: We next represent the value we seek with $x$.

Step 3: From step 1, it follows that $100\%=7.5$.

Step 4: In the same vein, $x\%=0.5$.

Step 5: This gives us a pair of simple equations:

$100\%=7.5(1)$.

$x\%=0.5(2)$.

Step 6: By simply dividing equation 1 by equation 2 and taking note of the fact that both the LHS

(left hand side) of both equations have the same unit (%); we have

$\frac{100\%}{x\%}=\frac{7.5}{0.5}$

Step 7: Taking the inverse (or reciprocal) of both sides yields

$\frac{x\%}{100\%}=\frac{0.5}{7.5}$

$\Rightarrow x=6.6666666666667\%$

Therefore, $0.5$ is $6.6666666666667\%$ of $7.5$.

Step-by-step explanation:

1

.36 repeating

2

because the 3 and the 6 repeat and it doesn't terminate

3

because the remainder is not 0 so that is why it repeats

Answer:

it the using of Pythagorean theorem.

Answer:

The output would depend on the input so relating this to the question, the input is the time (in minute) and the output is the amount of water left in the tank

We can give a letter 't' for the time, the input, and f(t) for the output

----------------------------------------------------------------------------------------------------------------

The original amount of water in the tank is 10450, so this will be the fixed constant.

The amount of water lost per minute is 270 so this will be the term that varies depends on the variable of time, we write this as 270t

The function is given f(t) = 10450 - 270t

--------------------------------------------------------------------------------------------------------------

Given, t = 10

f(10) = 10450 - 270(10)

f(10) = 7750 ml

Step-by-step explanation:

Answer:

 Part A:

Since the rate of 270 ml per minute has units of ml per minute, then yy must have units of ml and x must have units of minutes. The input must then be the number of minutes the tank is leaking for and the output is the number of ml of water remaining in the tank.

Part B:

Since the tank is leaking 270 ml per minute, then after x minutes, 270x ml of water has leaked out of the tank. The tank initially has 10,450 ml of water so after x minutes, there is y=10,450−270x ml remaining in the tank.

Part C:

After x=10 minutes, the amount of water remaining in the tank is y=10,450−270(10)=10,450−2,700=7,750 ml. There are 1,000 ml in 1 liter so 7,750 ml = 7.75 liters. There are then 7.75 liters of water left in the tank after 10 minutes.
