Answer:
the number of tomatoes he gathered for 3 days = 3 × x = 3x
Step-by-step explanation:
According to the question Stan gathered x number of tomatoes every single day for three days. The total number of tomatoes she gathered altogether can be calculated below.
The number of tomatoes she gathered daily = x
The number of tomatoes she gathered for 3 days will be the product of the daily number of tomatoes she gathered(x) and the number of days she gathered it(3).
Therefore,
the number of tomatoes he gathered for 3 days = 3 × x = 3x .
Or you could calculate the number of tomatoes she gathered for that 3 days by summing the number of tomatoes she had daily for that 3 days .
The firs day she gathered x number of tomatoes , the second day another x number and finally the last day another x number of tomatoes. Therefore,
x + x + x = 3x

Answer: 11
The range is the difference between the highest number and the lowest number
13 - 2 = 11 :)
Solve the quadratic equation. x2+x−6=0
Answer:
The value of x is -3 and 2.
Step-by-step explanation:
First, you have to elaborate the equation :
[tex] {x}^{2} + x - 6 = 0[/tex]
[tex] {x}^{2} - 2x + 3x - 6 = 0[/tex]
Next, you can factorize it by taking out the like-terms :
[tex]x(x - 2) + 3(x - 2) = 0[/tex]
[tex](x + 3)(x - 2) = 0[/tex]
Lastly you have to solve it :
[tex]x + 3 = 0[/tex]
[tex]x = - 3[/tex]
[tex]x - 2 = 0[/tex]
[tex]x = 2[/tex]
Answer:
[tex]x = 2[/tex] or (look down)
Step-by-step explanation:
[tex]x^{2}[/tex]+[tex]x[/tex]−[tex]60[/tex] [tex]=[/tex] [tex]0[/tex]
Answer:

The cost of 24 bottles of water is $6. How much does it cost for 10 bottles of water?
Find the unit rate: 24 water bottles ÷ 6 dollars total = $0.25 a water bottle
Next, take the rate per water bottle and multiply it by ten: $0.25 a water bottle x 10 bottles of water = $2.50 total
So, this gives you your final answer. Ten bottles of water cost you $2.50!
Which line on the graph below has a slope of zero? On a coordinate plane, line Q is horizontal, line P has a positive slope, line R is vertical, and line S has a negative slope.
Answer:
line q because it just is
Step-by-step explanation:
The line that has zero slope is horizontal in the coordinate plane. the correct option is (a).
What is the slope of straight line?The slope of a straight line is the tangent of the angle formed by it with the positive x axis as the reference. The negative slope indicates the rate of decrease while the positive shows the rate of increase.
The given options can be analysed one by one as follows,
(a) A horizontal line on a coordinate plane is parallel to x axis.
The angle the line makes with x axis is zero which implies the slope is also zero.
(b)The line in the given case has some positive value of slope.
(c) A vertical line makes right angle with x axis.
Thus, the slope is tan(90°) = ∞,.
(d) The line in the given case has some negative value of slope.
Hence, the horizontal line will have zero slope.

Ed is constructing the perpendicular bisector of a segment on his paper. He just finished
labeling the points of intersection of the two arcs that he drew. What is his next step?
Answer:
The next step is to draw a line connecting the two labelled points, that is from one side of the line to be bisected to the other
The line drawn in the above step, from the two labelled points is the perpendicular bisector of the segment
Step-by-step explanation:
To draw a perpendicular bisector of a segment, we have;
1. Ensure the compass is opened to more than half of the length of the segment to be bisected
2. Draw arcs of the same radius with center at the ends of the line to be bisected
3. Label the points where the arcs drawn from both ends cross each other on opposite sides of the line
4. Draw a line connecting the two labelled points, that is from one side of the line to be bisected to the other
5. The line so drawn from the two labelled points is the perpendicular bisector of the segment.
Which equation has no solution?
Answer:
B. 5 + 2(3+2x) = x + 3(x+1)
Step-by-step explanation:
5 + 2(3+2x) = x + 3(x+1)
5 + 6 + 4x = x + 3x + 3
11 + 4x = 4x + 3
4x - 4x = 3 - 11
0 = - 8, which is absurd.
Hence the equation 5 + 2(3+2x) = x + 3(x+1) has no solution.
A square fits exactly inside a circle with each of its vertices being on the circumference of the circle.
The square has sides of length x cm.
The area of the circle is 56cm squared.
Work out value of x.
Give answer correct to 3 significant figures.
Answer:
The side of the square is 5.971 cm
Step-by-step explanation:
If the square fits the circle exactly, then its diagonal is equal to the diameter of the circle. Since the side of the square has a length of [tex]x[/tex] cm, then it's diagonal have the length of [tex]x\sqrt2[/tex] cm. Using the circle's area we can find the diagonal of the square, as shown below:
[tex]area = \pi*r^2\\56 = pi*r^2\\r^2 = \frac{56}{\pi}\\r = \sqrt{\frac{56}{\pi}}\\r = 4.222[/tex]
Since the diameter of the circle is the same as the diagonal of the square, then:
[tex]x\sqrt{2} = 2*r \\x = \frac{2*r}{\sqrt{2}}\\x = \frac{2*4.222}{\sqrt{2}}\\x = 5.971[/tex]
The side of the square is 5.971 cm

Corrected Question
The blueprint for the Moreno Moreno's living room has a scale of 2 inches equals 7 feet.The family wants to use a scale of 1 inch equals = 6 feet. What is the width of the living room on the new blueprint? A rectangle is labeled width = 12 inches.
Answer:
7 Inch
Step-by-step explanation:
The width of the room on the old blueprint = 12 Inches
Scale on the old blueprint:
2 inches = 7 feet.
Therefore: 1 Inch =7/2 feet
12 Inches =12 X 7/2 feet =42 feet
The actual width of the room is 42 feet.
Scale on the new blueprint
1 inch equals = 6 feet; which we can reorder as:
6 feet=1 inch
1 feet =1/6 Inch
Therefore:
42 feet = 42 x 1/6 Inch =7 Inch
Thus, the width of the living room on the new blueprint is 7 Inch.
A cylinder has a volume of 792cm3 and a radius of 6m find its height
Answer:
Step-by-step explanation:
7
Answer:
≈ 7
Step-by-step explanation:
the formula of the volume of a cylinder is:
V = π r^2 * h
792 = 3.14 * 6^2 *h
so first divide by 6^2 (or 36) on both sides so you can start to isolate h
36/36 = 1 and 792/36 = 22
22 = 3.14 *h
now divide by 3.14 to get h by itself
3.14/3.14 = 1 and 22/3.14 ≈ 7
the answer is approximately 7 and precisely 7.002817496

what is the answer for this in square root form
Answer:
x = ± sqrt(-49)
or x = ± 7i
Step-by-step explanation:
x^2 +49 = 0
Subtract 49 from each side
x^2 +49 -49 = 0-49
x^2 = -49
Take the square root of each side
sqrt(x^2) = ± sqrt(-49)
x = ± sqrt(-49)
We have to complex numbers to solve
x = ± sqrt(-1) sqrt(49)
sqrt(-1) = i
x = ±i *7
x = ± 7i

En 16 días se consume 1/8 de la carga de una batería. ¿Cuantos se consumirá en 48 días?
Answer: 3/8
Step-by-step explanation:
1/8 of the charge of a battery is consumed in 16 days. How will be consumed in 48 days?
So, to answer this question we simple have to apply a proportion:
(1/8 )/16 = charge consumed /days
For 48 days= x /48 days
(1/8 )/16 = x/48
Solving for x (charge)
[(1/8 )/16] 48 = x
3/8 =x

Two solutions of salt water contain 0.06% and 0.21% salt respectively. A lab technician wants to make 1 liter of solution which contains 0.12% salt. How much of each solution should she use?
Answer:
The first solution must have 0.6 l and the second one 0.4 l.
Step-by-step explanation:
The volume of the first solution will be called "x", while the one from the second will be "y". The salt content on the first solution is "0.0006*x", while the salt content on the second solution is "0.0021*y", and the sum of these two values must be the same as the one in the final solution, so we have:
0.0006*x + 0.0021*y = 0.0012
And the sum of volumes must be equal to 1 liter.
x + y = 1
We have the equation system:
x + y = 1 (1)
0.0006*x + 0.0021*y = 0.0012 (2)
Isolating the "x" variable in the first equation and applying it in the second we have:
x = 1 - y
0.0006*(1-y) + 0.0021*y = 0.0012
0.0006 - 0.0006*y + 0.0021*y = 0.0012
0.0015*y = 0.0006
y = 0.0006/0.0015 = 0.4
x = 1 - 0.4 = 0.6
The first solution must have 0.6 l and the second one 0.4 l.
