Answer:
62, 64, 66
Step-by-step explanation:
I like to work "consecutive integer" problems by considering the average, or middle value. If we call that x, then the problem statement tells us ...
(x -2) +(x +2) = 128
2x = 128 . . . . . collect terms
x = 64 . . . . . . . divide by 2
The middle integer is 64, so the three even integers are 62, 64, 66.

Brenda has two pieces of string, one 28 feet long and the other 42 feet long. For an art project, she wants to cut them up to produce many pieces of string that are all of the same length, with no string left over. What is the greatest length, in feet, that she can make them?
Answer:
7 feet
Step-by-step explanation:
Length of one piece of string = 28 feet.
Length of the second string = 42 feet.
Since the number of required pieces was not given but many are required, the greatest length can be determined by;
If the maximum length is 7 feet, then:
the number of pieces from 28 feet long string = [tex]\frac{28}{7}[/tex]
= 4
Also,
the number of pieces from the 42 feet lone string = [tex]\frac{42}{7}[/tex]
= 6
Total number of 7 feet strings that she can make = 4 + 6
= 10
Since many pieces are required, the greatest length she can make is 7 feet. If she increase the length to 14 feet, the number of pieces would be 5 which limit the required number.

The angle between a diagonal and the longer base of the isosceles trapezoid MNFD is 45°. NK is an altitude to the longer base. If MD = 9 and NF = 5, find:
Answer:
NK = 7, MK = 2, MF = 9.9, Area = 42Step-by-step explanation:
Refer to attached
To find:
NK , MK, MF, Area of trapezoidSolution
The trapezoid is isosceles and NK is its height, therefore
MD - NF = 2MKMK = (9 -5)/2 = 2Since ∠KDN = 45°, the triangle NKD is isosceles and so
NK = KD = MD - MK = 9 - 2 = 7MF = ND as trapezoid is isosceles and therefore diagonals are equal
ND = NK√2 = 7√2 = 9.9 So MF = 9.9Area of trapezoid
A = 1/2(b1 + b2)h A = 1/2(9+5)(7) = 6*7 = 42Write an equation of the line in standard form.
The line has the same slope as 3x-y=5 and the same y-intercept as the graph of 2y- 15x = 8.
The equation in standard form is
Answer:
Ok to make this easier for us we should switch these equations into y=mx+b so that it's easier for us to identify the slope and y-intercept:
to switch into y=mx+b form do this:
3x-y=5
-y=5-3x
y=-5+3x
y=3x+(-5)
2y-15x=8
2y=8+15x
y=4+7 1/2x
y=7 1/2x+4
THe slope of any line in y=mx+b form is m. Therefore in this equation:
y=3x+(-5) 3 is the slope
The y intercept of any line is the +b:
y=7 1/2x+4 -therefore 4 in this equation is our y intercept.
Now we can construct our equation in y=mx+b then into standard form (Ax+By=C)
since 3 is our slope and 4 is our y intercept the equatuon is :
y=3x+4
NOw all we need to do is move this into standard form:
y=3x+4
-3x+y=4
-3x+y=4 is your final answer

Thirty more than one half of the students at at canyon middle school are in band.Five less than three fifths of the students are in athletics.If the number of students who are in band is equal to the number of students in athletics how many students are enrolled in canyon middle school
Answer:
Students at canyon middle school = 350
Step-by-step explanation:
Students at canyon middle school = x
Band = 1/2x + 30
Athletics = 3/5x - 5
athletics.If the number of students who are in band is equal to the number of students in athletics
1/2x + 30 = 3/5x - 5
1/2x - 3/5x = -5 - 30
5x-6x/10 = -35
-x/10 = -35
= -x(1/10)= -35
x = -35 ÷ -1/10
= -35 × -10/1
= 350
x = 350
Students at canyon middle school = 350
30 Willow trees are distributed over a geographic area consisting of 50 acres. what is the population density in terms of willow tree per acre?
Answer:
There is 1 tree per 1.6 acre.
Step-by-step explanation:
Divide the number of trees from the number of acres. This will tell you how many acres are between each tree.
Answer:
0.6 acres.
Step-by-step explanation:
You divide the total population of the willow tree (30) by the areas they occupy (50 acres). Therefore, 30/50=0.6 population per acre.

The slope of a roof is called its pitch. The Parthenon, an ancient Greek temple, has a roof with a rise of 3.6 meters and a run of 12 meters. What is the pitch of the roof?
Answer:
3.6/12, or 0.3
Step-by-step explanation:
To determine a slope on a graph, it's always the "rise over run", or "fall over run" if it's a negative slope.
In this case, the rise of 3.6 meters would represent the top number, and 12 meters would be 12 meters, so it's 3.6/12.

Correct question is;
1) Milk and cream are mixed together for a recipe. The total volume of the mixture is 1 cup. If the milk contains 2% fat, the cream contains 18% fat, and the mixture contains 6% fat, how much cream is in the mixture?
2) Fifteen percent of the pigment in paint color A is black. Sixty percent of the pigment in paint color B is black. An unknown amount of paint color B is mixed with 40 ml of paint color A, resulting in a paint that contains 25% black pigment. Which equation can be used to solve for x, the total amount of paint in the mixture of the two colors?
A) 0.15(40) + 0.6x = 0.25(40 + x)
B) 0.15(40) + 0.6(x – 40) = 0.25(x)
C) 0.15(40) + 0.6x = 0.25(40 – x)
D) 0.15(40) + 0.6(x + 40) = 0.25(x)
Answer:
1) Amount of cream = ¼cup
2) Option D: 0.15(40) + 0.6(x - 40) = 0.25x
Step-by-step explanation:
1) First of all, let x represent the amount of cup of milk and let y represent the of cup of cream.
We are told that the volume of the mixture is 1 cup.
Thus;
x + y = 1 - - - (eq 1)
We are now told that the milk contains 2% fat, the cream contains 18% fat, and the mixture contains 6% fat
Thus, x contains 0.02 fat, y contains 0.18 fat and the 1 cup of mixture contains 0.06 fat.
Thus, we will multiply the respective terms in eq 1 by these %fat content.
Thus;
0.02x + 0.18y = 0.06(1)
0.02x + 0.18y = 0.06 - - - (eq 2)
From eq 1, let's make y the subject which is the amount of cup of cream.
Thus,
y = 1 - x
Let's put 1 - x for y in eq 2 to get;
0.02x + 0.18(1 - x) = 0.06
0.02x + 0.18 - 0.18x = 0.06
0.18x - 0.02x = 0.18 - 0.06
0.16x = 0.12
x = 0.12/0.16
x = 3/4 cup
From,y = 1 - x;
y = 1 - (3/4)
y = ¼ cup
Amount of cream = ¼cup
2) We are given;
15% of the pigment in paint color A is black.
60% of the pigment in paint color B is black.
We are now told that Alan unknown amount of paint color B is mixed with 40 ml of paint color A, resulting in a paint that contains 25% black pigment.
If we assume the total amount of paint in the mixture is x like we are told, it means that based on the given data, we have a sum of;
0.15(40) + 0.6(x - 40)
Thus is because we know the amount of paint A used as 40 but don't know the amount of paint B used.
Now we are told that this sum produces a mixture that contains 25% black pigment. Since the total amount in the mixture is x. Thus, this final product is 0.25x.
Therefore to derive an equation to find the total amount of paint in the mixture of the two colors, we will equate the sum of the 2 Mixtures to the final product.
This gives;
0.15(40) + 0.6(x - 40) = 0.25x

how do u find the slope of the line and for y=9x - 5/2
Answer:
slope = 9 y-intercept = -5/2
Step-by-step explanation:
since slope form is y=mx+b we know that m= slope and b=y-intercept. since 9 is in place of the m that shows that 9 is the slope. since 5/2 is in the b place you would think the y-intercept would be 5/2 but since the equation is - 5/2 instead of + 5/2 it would be + (-5/2) making the y-intercept negative. hope this helped. :)
