A builder needed to buy one hundred fifty-four boards for his latest project. If the board he needs comes in packs of three, how many packets will he need to buy
Answer:
51.3 packets or 51 1/3 packers
Step-by-step explanation:
From the above question:
The board he needs comes in packs of three. This means
1 pack = 3 boards
Hence:
3 boards = 1 packet
154 boards = x
Cross Multiply
3x = 154
x = 154/3
x = 51.333333333 packets
Approximately = 51.3 packets or 51 1/3 packers
The builder will need to buy 51.3 packets or 51 1/3 packers

y = -2/3 x in standard form
Answer: y = -2/3x in standard form is 2x + 3y = 0
Answer:
x + y = -2/3
Step-by-step explanation:
When changing something to standard form, you want all variables on one side, and the remaining numbers gone.
There are 1,200 bacteria in a lab dish. The population decreases 10% per day. Compare the decrease in the population for days 1 to 3 with the decrease for days 4 to 6.
Complete the sentence with “more quickly,” “less quickly,” or “at
the same rate.”
The population decreases [ Select ] from day 1 to day 3 than from day 4 to day 6.
The population decreases more quickly from day 1 to day 3 than from day 4 to day 6.
What is Percentage?percentage, a relative value indicating hundredth parts of any quantity.
Given,
The total number of bacteria in lab dish is 1200
The population decreases 10% per day
In first day:
10/100×1200=120
120 bacteria decreased in lab
1200-120=1080
In second day:
0.1×1080=108
1080-108=972
In third day
0.1×972=97.2
972-97.2=874.8
In fourth day
0.1×874.8=87.48
874.8-87.48=787.32
In fifth day
0.1×787.32=78.732
787.32-78.732
708.588
The population decreases more quickly from day 1 to day 3 than from day 4 to day 6.
Hence, the population decreases more quickly from day 1 to day 3 than from day 4 to day 6.

A faucet fills 1/3 of a water cooler in 1/12 of an hour At this rate how long does it take the faucet to fill the cooler completely
Answer:
[tex]\frac{1}{4}\:\mathrm{of\:an\:hour\: or\:}15\:\mathrm{minutes}[/tex]
Step-by-step explanation:
If the faucet fills [tex]\frac{1}{3}[/tex] of the water cooler in [tex]\frac{1}{12}[/tex] of an hour, then it will take the faucet [tex]\frac{1}{\frac{1}{3}}\cdot \frac{1}{12}=3\cdot\frac{1}{12}=\fbox{$\frac{1}{4}$}[/tex] of an hour to fill the faucet completely.

PLS HELP ME! Joye has a circular garden with a diameter of 24 feet. If she uses 2 cups of fertilizer for every 10 square feet, how much fertilizer will Joye use for her garden? Use 3.14 for pi
Answer:
90.5 cups
Step-by-step explanation:
Step one:
Given data
diameter= 24ft
radius= 12 ft
area= πr^2
Area= 3.142*12^2
Area= 3.142*144
Area= 452.448 ft^2
Hence if
2 cups of fertilizer for every 10 square feet
x cups will do for 452.448 ft^2
cross multiply we have
x= 452.448 *2/10
x=904.896/10
x=90.5 cups
Find the value of x.
Step-by-step explanation:
(3x+24)°=(8x-11)°
24+11=8x-3x
35=5x
x=7
What is the slope of a line parallel to the line whose equation is y=3x + 4?
Answer:
The slope of any line parallel to y=3x+4 would be 3!
Step-by-step explanation:
When lines are parallel, they always have the same slope!
When lines are perpendicular, the slope would be the negative reciprocal!

Find the roots of the following factored quadratic equation.
y= (2x-9) (7x-4)
Answer:
x = 4.5, 4/7
Step-by-step explanation:
To find the roots of a factored equation you need to set the y value at 0, that way you can solve for x. Once you solve for x you get two quantities, which can be graphed. These two quantities are where the x intercepts are.
One solution to a quadratic equation is x = -2i
What is the other solution?
I believe it would be x=2i

Step-by-step explanation:
y-intercept in the point x = 0
B) is the easiest
g(x) or y value
g(x) = 3x² + 6x -9

Rewrite the explicit formula in function form. The identify the y
intercept of the function.
an = 9-3(n-1)
Answer: y-intercept: (0, 12)
Step-by-step explanation:
[tex]a_n[/tex] = 9 − 3 (n − 1)
Use the slope-intercept form to find the slope and y-intercept.
The slope-intercept form is y = mx + b, where m is the slope and b is the y-intercept.
y = mx + b
Find the values of m and b using the form y = mx + b.
m = −3
b = 12
The slope of the line is the value of m, and the y-intercept is the value of b.
Slope: −3
intercept: (0, 12)
Any line can be graphed using two points. Select two x values, and plug them into the equation to find the corresponding y values.
Find the x-intercept.
To find the x-intercept(s), substitute in 0 for y and solve for x.
0 = −3x + 12
Solve the equation.
Rewrite the equation as −3x + 12 = 0.
−3x + 12 = 0
Subtract 12 from both sides of the equation.
−3x = −12
Divide each term by −3 and simplify.
x = 4
x-intercept(s) in point form.
x-intercept(s): (4, 0)
Find the y-intercept.
To find the y-intercept(s), substitute in 0 for x and solve for y.
y = −3 ⋅ 0 + 12
Solve the equation.
Remove parentheses.
y = −3 ⋅ 0 + 12
Simplify −3 ⋅ 0 + 12.
y = 12
intercept(s) in point form.
intercept(s): (0, 12)
Create a table of the x and y values.
x | y
0 | 12
4 | 0
Graph the line using the slope and the y-intercept, or the points.
Slope: −3
intercept: (0, 12)

10. The test was worth 100 points. There were 28 problems on the test. Some of the
problems were worth 3 points and others were worth 5 points. How many of each were
there?
Answer:
There are 20 3-point questions and 8 5-point questions
Step-by-step explanation:
x=3 point y=5 point
x+y=28 ----> x=28-y
3x+5y=100
3(28-y)+5y=100
84-3y+5y=100
84+2y=100
2y=16
y=8
28-8=20
Answer:
20 3-point questions and
8 5-point questions.
Step-by-step explanation:
Let there be x 3 point problems and y 5 point problems. So we have:
x + y = 28 Multiply this equation by -3:
-3x - 3y = -84
3x + 5y = 100 Adding the last 2 equations:
0 + 2y = 16
y = 8
So x = 28 - 8 = 20.
