(2 5/8 +4 8/17 )+( 9/17 +3 3/8 )

Mr Abbot's son mowed more of the lawn. In total, they mowed 19/28 or approximately 68% of the lawn. Hence, approximately 32% or 9/28 of the lawn still has to be mowed.

To find out who mowed more lawn and how much of the lawn is still left to be mowed, we need to compare the fractions and then add them together.

Mr. Abbot mowed 1/4 of his lawn and his son mowed 3/7 of it. To compare these fractions, you can turn them into decimals or percent by dividing the numerator (the top number) by the denominator (the bottom number). Doing that, we find Mr. Abbot mowed 0.25 (or 25%) of the lawn and his son mowed approximately 0.43 (or 43%) of the lawn. Therefore, the son has mowed more lawn.

To figure out how much lawn is still left to be mowed, we add up the fractions of the lawn that Mr. Abbot and his son mowed: [tex]1/4 + 3/7 = 7/28 + 12/28 = 19/28[/tex]. Thus, 19/28 of the lawn have been mowed, and to figure out what fraction is left, we subtract this number from 1 since 1 represents the whole or 100% of the lawn: [tex]1 - 19/28 = 9/28[/tex]. So, 9/28 of the lawn still needs to be mowed.

a. Twenty-three ninth graders and fifteen eleventh graders prefer math.

b. Fourteen eleventh graders prefer math and eight tenth graders prefer English.

c. Thirty-five twelfth graders prefer math and nine tenth graders prefer English.

d. Twenty-three ninth graders and thirty-five twelfth graders prefer math.

e. Eighteen tenth graders prefer English and fourteen eleventh graders prefer math.

Answer:

Therefore, the correct options are;

b. and d.

Step-by-step explanation:

Here we have a table with blank boxes and totals from which we can fill the boxes;

For the 12th graders, we have a total of 67 pupils with 32 preferring English, therefore the number of the 12th graders that prefer math is 67 - 32 = 35 pupils

Similarly for the 11th graders we have total pupils = 29 with 15 preferring English, therefore the number of the 11th graders that prefer math is 29 - 15 = 14 pupils

Also for the 10th graders we have total pupils = 26 with 18 preferring math, therefore the number of the 11th graders that prefer English is 26 - 18 = 8 pupils

Finally for the 9th graders, we have a total of 63 pupils with 40 preferring English, therefore the number of the 9th graders that prefer math is 63 - 40 = 23 pupils

From the above, the correct option is

Step-by-step explanation:

Substituting the solution (2,10) into both equations of the system shows that it does not satisfy either equation, hence it is not a valid solution.(Choice B.No)

To verify the solution of the system of equations, we can substitute the ordered pair (2,10) into both equations. Let's do this:

Since the ordered pair (2,10) does not satisfy either of the two given equations, we can say that (2,10) is not a solution of the system of the equations.

The point (2,10) is not a solution to the system of equations -3x - 4y = 4 and -5x + y = 2, as it does not satisfy either equation when substituted.

To determine if the point (2,10) is a solution of the given system of equations:

-3x - 4y = 4

-5x + y = 2
we need to substitute x=2 and y=10 into each equation to see if the left-hand side equals the right-hand side.

For the first equation:

-3(2) - 4(10) = -6 - 40 = -46
which does not equal 4, therefore the point (2,10) is not a solution to this equation.

For the second equation:

-5(2) + (10) = -10 + 10 = 0
which does not equal 2, so (2,10) is also not a solution to the second equation.

Since (2,10) does not satisfy either equation, we can conclude that:

(Choice B)
No, (2,10) is not a solution to the system of equations.

Answer:

B. x=2

Step-by-step explanation:

The formula to find the axis of symmetry is -b/2a.

So, in this case, we find our b and a, which are 3 and -12.

Plug them into the formula.

-(-12)/2(3)

The negative sign times another negative makes it into a positive, now we have a positive 12 and then 2 multiplied by 3 equals 6.

Our new equation is 12/6.

Then, simply solve it, 12 divided by 6 equals 2.

Therefore, B would be your answer, x=2.

The axis of symmetry of the parabola defined by the equation y = 3x^2 - 12x + 11 is x = 2.

To find the axis of symmetry of the parabola defined by the equation y = 3x2 - 12x + 11,

we can use the formula for the axis of symmetry for a parabola in standard form which is x = -b/2a.

In this equation, a is the coefficient of x2, which is 3, and b is the coefficient of x, which is -12.

Plugging the values into the formula, we get x = -(-12)/(2*3) = 12/6 = 2.

Therefore, the axis of symmetry of the given parabola is x = 2.

Final answer:

The area of a regular hexagon with an apothem of 15 cm is approximately 1166.55 cm².

Explanation:

The area of a regular hexagon can be found by using the formula:

Area = (3 x apothem x side length) / 2

In this case, the apothem is given as 15 cm. We need to find the side length to calculate the area. The side length can be found using the formula:

side length = 2 x apothem / tan(180° / 6)

Using a calculator, we can find that the side length is approximately 25.98 cm. Plugging in the values into the area formula, we get:

Area = (3 x 15 cm x 25.98 cm) / 2 = 1166.55 cm²

Answer: 8(4p + 3)

Step-by-step explanation: Let's first rewrite this as 32p + 24.

If you're asked to factor a polynomial, the first thing you want to look for is the greatest common factor between the terms that are involved.

So what is the greatest common factor between 32p and 24?

Well if you use a factor tree, you'll figure out that the greatest common factor between 32p and 24 is 8.

What that means is that 2 factors out of this polynomial and what you're left with is each of these terms divided by the number that factors out.

In other words 32p divided by 8 or 4p and 24 divided by 8 which is 3.

So your answer is 8(4p + 3) and that is a factored version of 24 + 32p.

Answer:

Y=40

Explanation:

Due to the nature of both X and Y varying directly, you can view the problem as a proportion. If x=6 and y=30, that must mean that when x=8  y must equal 40.

6:30 = 8:40

or

30/6= 5

Y/8= 5

Because they vary directly they are equivalent, and so multiply 8 by 5 and get 40.

Answer:40

Step-by-step explanation:

6 times 5 is 30

Step-by-step explanation:

Total females: 48

Female and invisibility: 32

P(invisibility/female) = 32/48

2/3

The probability that a female student chose invisibility as their superpower is 2/3

Probability determines the chance that an event would occur. The chance that an event would occur is between 0 and 1. It is zero if the event does not occur and 1 if the event occurs.

In this question, two groups of students were surveyed : male and female. Also, there were three groups of superpowers: fly, indivisibility and others.

The probability of a female student chose indivisibility as superpower = number of female students that chose indivisibility as superpower / number of female students

= 32/48

To simplify, divide both numerator and the denominator by 18

= 2/3

Answer:

The absolute error is 0.2

The percent error is 1.45

Step-by-step explanation:

Please kindly check the attached for explanation

The absolute error of the police officer's estimate is 0.2, and the percent error is approximately 1.5%

In Mathematics, absolute error is determined by the absolute value of the difference between the estimated value and the actual value. Therefore, the absolute error in this case is |14 - 13.8| = 0.2.

Percent error, on the other hand, is calculated by first finding the absolute error, then dividing the absolute error by the actual measurement, and finally multiplying the result by 100% to turn it into a percentage. So in this case, the percent error is given by (0.2 / 13.8) * 100 = 1.45%. Since we should round it off to the nearest tenths, the percent error will be roughly 1.5%.

Answer: No.

Step-by-step explanation: Joe is 4'6" tall. Convert 54" to feet by dividing by 12. 54/12=4.5. Half of a foot is 6 inches.

Joe is 54 inches tall, which is taller than the kid zone's maximum allowed height of 52 inches (4 feet 4 inches). Therefore, he is not allowed to play in the kid zone area.

To determine if Joe is allowed to play in the kid zone area, we must compare his height to the maximum height allowed for the kid zone. The maximum height for the kid zone is 4 feet 4 inches, which needs to be converted to inches to compare easily with Joe's height.

First, we know that 1 foot equals 12 inches. So, 4 feet is equal to 4 x 12 inches, which is 48 inches. Adding the extra 4 inches from the height limit gives us 48 + 4 inches, which is 52 inches. This is the maximum height allowed for the kid zone.

Since Joe is 54 inches tall, which is greater than the maximum 52 inches, it means he is too tall to play in the kid zone. Therefore, he is not allowed to play there according to the height restriction.
