Team A and Team B play in a competition. Team A has twelve more points than Team.

Team A has five as many points as Team B.

How many points doe each team have?

Team A and Team B play in a competition.

Team A has twelve more points than Team B.

Team A has five times as many points as Team B.

How many points does each team have?

Answer:Team A has 15 points and Team B has 3 points

Solution:Given that Team A and Team B play in a competition

Let "a" represent points of team A

Let "b" represent points of team B

Given that Team A has twelve more points than Team B

So we can frame a equation as:

points with team A = 12 + points with team B

a = 12 + b --- eqn 1

Also given that Team A has five as many points as Team B

So we can frame a equation as:

points with team A = 5(points with team B)

a = 5b --- eqn 2

Substitute eqn 2 in eqn 1

5b = 12 + b

4b = 12

b = 3

Therefore from eqn 2,

a = 5b = 5(3) = 15

Thus team A has 15 points and Team B has 3 points

Tell whether the lines for each pair of equations are parallel, perpendicular, or neither. y=(-1/4)x+8 and -2x+8y=4

First put the equations into slope intercept form to analyze the slopes.

y= (-1/4)x+8

-2x+8y=4

8y= 2x+4

y= (1/4)x+(1/2)

These two equations are neither because they do not have equivalent slopes or negative reciprocals of the slopes.

Hope this helps.

y= (-1/4)x+8

-2x+8y=4

8y= 2x+4

y= (1/4)x+(1/2)

These two equations are neither because they do not have equivalent slopes or negative reciprocals of the slopes.

Hope this helps.

Comparing both the equations with slope-intercept form( y=mx+c), slope of y=(-1/4)x + 8 is m = -1/4 and slope of -2x + 8y = 4 is m'=1/4. For lines to be parallel, their slopes must be same which is not. For lines to be perpendicular, product of their slopes must be -1 which here is 1/4 x -1/4 = -1/16. Hence they are neither parallel nor perpendicular.

What is (5 7/8 minus 6 3/4) minus 2 1/4 ? Please give me the correct answer and stepy by step instructions.

(5 7/8-6 3/4)-2 1/4

Solve the numbers in the parenthesis ( I change the denominators to a common denominator that 8 and 4 share)

(5 7/8 - 6 3/4)-2 1/4

^

-1 1/8-2 1/4

(I use KKC aka Keep Change Change where I keep -1 1/8 the same, change the minus sign to a plus sign, and change the -2 1/4 to positive) ( I change the denominators to a common denominator that 8 and 4 share)

-1 1/8 + +2 1/4 = 1 1/8

Solve the numbers in the parenthesis ( I change the denominators to a common denominator that 8 and 4 share)

(5 7/8 - 6 3/4)-2 1/4

-1 1/8-2 1/4

(I use KKC aka Keep Change Change where I keep -1 1/8 the same, change the minus sign to a plus sign, and change the -2 1/4 to positive) ( I change the denominators to a common denominator that 8 and 4 share)

-1 1/8 + +2 1/4 = 1 1/8

7 is 10% of y. What was franklin's age

Franklin is 70 years of age since 7 is 10% so 10 x 7 = 70

To find 19 + (11+37), Lennie added 19 and 11. Then he added 37 to the sum. What property did he use?

Lennie used associative law of addition.

a + (b + c) = (a + b) + c

hope that helps, God bless!

a + (b + c) = (a + b) + c

hope that helps, God bless!

He used associative property

Let divf = 6(5 − x) and 0 ≤ a, b, c ≤ 12. (a) find the flux of f out of the rectangular solid 0 ≤ x ≤ a, 0 ≤ y ≤ b, and 0 ≤ z ≤ c. your answer will be in terms of a, b,

c. flux = (b) for what values of a, b, c is the flux the largest? what is that largest flux?

The largest flux will be 10,800.flux of f out of the rectangular solid 0 ≤ x ≤ a, 0 ≤ y ≤ b, and 0 ≤ z ≤c

What is flux?Flux describes any effect that appears to pass or travel (whether it actually moves or not) through a surface or substance.

Flux is a concept in applied mathematics and vector calculus that has many applications to physics. For transport phenomena,

Continuing from the setup in the question linked above (and using the same symbols/variables), we have

The next part of the question asks to maximize this result - our target function which we'll call subject to

We can see that g is quadratic in a, so let's complete the square.

Since bc are non-negative, it stands to reason that the total product will be maximized if a-5 vanishes because 25-(a-5)^2 is a parabola with its vertex (a maximum) at (5, 25). The Setting, a=5

it's clear that the maximum of g will then be attained when bc is largest, so the largest flux will be attained at (a,b,c)=(5,12,12) , which gives a flux of 10,800.
