Answer:
The store sold 20 more ink jet printers than laser printers.
Step-by-step explanation:
Since the store sold 100 printers, you can say that the result of adding up the numbers of each type of printers sold is equal to 100, which is:
x+y=100, where:
x is the number of ink jet printers sold
y is the number of laser printers sold
Also, you know the amount the profit the store gets for each type of printer and the total profit received on Monday which means that adding up the results of multiplying each type of printer for its price is equal to the total profit, which can be expressed as:
40x+55y=4,600
Now, you have two equations:
x+y=100 (1)
40x+55y=4,600 (2)
You have solve this system of equations to find the number of ink jet and laser printers that were sold. First, you have to solve for x in (1):
x=100-y (3)
Then, you have to replace (3) in (2) and solve for y:
40(100-y)+55y=4,600
4000-40y+55y=4,600
15y=600
y=600/15
y=40
Finally, you can replace the value of y in (3) to find the value of x:
x=100-40
x=60
Now that you know that the store sold 60 ink jet printers and 40 laser printers, you can find the difference between this numbers to be able to know how many more ink jet printers were sold:
60-40=20
According to this, the answer is that the store sold 20 more ink jet printers than laser printers.

Find the value of x and y that will make each quadrilateral a parallelogram.
Step-by-step explanation:
2x+5=3x-12
or, 2x-3x=5-12
or, -x= -7
i.e X=7
again
y+4=3x+2
or, y+4=3*7+2
or, y+4=21+2
or, y+4=23
or, y =23-4
i.e y = 19
hence, the value of X is 7 and y is 19

Marcy mailed a package weighing1.337 kilograms. How does the value represented by the 3 in the tenths place compare with the value represented by the 3 in the hundredths place?
If a number has a decimal point , then the first digit to the right of the decimal point indicates the number of tenths. The second digit to the right of the decimal point indicates the number of hundredths.
In this case the .3 indicates 3/10ths of a kilogram. or 300 grams!
In the other case 0.03 indicates 3/100ths of a kilogram or 30 grams!
So, to compare the two:
the tenths decimal is 10 times bigger than the decimal in the next spot (hundredths)

Consider a person from birth to age 18 and the height of that person each of the years between birth and age 18. Which best describes the variables of age and height?
no correlation
positive correlation
negative correlation
Answer:
Seems to be no correlation at all.
Answer:
anges between -1 and +1 and quantifies the direction and strength of the linear association between the two variables. The correlation between two variables can be positive (i.e., higher levels of one variable are associated with higher levels of the other) or negative (i.e., higher levels of one variable are associated with lower levels of the other).
The sign of the correlation coefficient indicates the direction of the association. The magnitude of the correlation coefficient indicates the strength of the association.
For example, a correlation of r = 0.9 suggests a strong, positive association between two variables, whereas a correlation of r = -0.2 suggest a weak, negative association. A correlation close to zero suggests no linear association between two continuous variables.
It is important to note that there may be a non-linear association between two continuous variables, but computation of a correlation coefficient does not detect this. Therefore, it is always important to evaluate the data carefully before computing a correlation coefficient. Graphical displays are particularly useful to explore associations between variables.
The figure below shows four hypothetical scenarios in which one continuous variable is plotted along the X-axis and the other along the Y-axis.

ABCD is a cyclic quadrilateral (inscribed quadrilateral). Find the value of x and the measures of all the angles.
Answer:
Step-by-step explanation:
The "trick" to this problem is knowing that opposite sides of the box add up to 180°
Now that you know that maybe you can solve this?
180= 7x+2 + 6x-4
180 = 13x -2
182 = 13x
14 = x
find y now to find all the angles
180 = 2y + 4 +4y - 4
180 = 6y
30 = y
now solve the x expressions and the y expressions
7x+2
7(14)+2
98 + 2
D= 100°
6x-4
6(14)-4
84-4
B = 80°
2y + 4
2(30) + 4
60 + 4
A = 64°
4y-4
4(30)-4
120-4
C = 116°

The area of the parallelogram will be 98 square feet.
What is a parallelogram?It is a polygon with four sides. The total interior angle is 360 degrees. A parallelogram's opposite sides are parallel and equal.
Let h be the perpendicular distance between the parallel side and b be the length of the base of the rectangle.
Then the area of the parallelogram will be given as,
Area of parallelogram = b x h
The length of the base of the parallelogram is 14 feet, and the value of h is 7 feet.
Then the area of the parallelogram will be
Area pf parallelogram = 14 x 7
Area pf parallelogram = 98 square feet
Then the area of the parallelogram will be 98 square feet.

The cost of electricity is obtained as follows: A fixed charge of $(a), rent of a meter $(b) and a charge of (c) cents for unit of electricity supplied Determine the total cost of using n units of electricity.
Answer:
$(a + b) + cn cent
Step-by-step explanation:
Given :
Fixed charge = $a
Rent of a meter = $b
Charge per unit of electricity = c cents
The total cost of using n units of electricity :
For n units of electricity ;
Fixed charge is paid once
Meter rent is paid once
The cost of electricity = (number of units * cost per unit) = (n * c) = nc cents
Total cost of n units of electricity :
$(a + b) + cn cent

Answer:
The surface area of the shape is 292 in^2
Step-by-step explanation:
Here, we want to find the surface area of the cuboidal shape
Mathematically, the area of a cuboid can be calculated using the formula;
A = 2(lb + lh + bh)
where l is the length which is 7 inches
b is the breadth which is 6 cm
h is the height which is 8 cm
Substituting these values, we have
A = 2((8 * 6) + (7 * 6) + (8 * 7))
A = 2(56 + 42 + 48)
A = 2 * 146
A = 292 in^2

Divide 270 and 30
270/30 = 9
Then multiply 6 and 9

What two numbers multiply to +34 and add to -19
Answer:
17 * 2 = 34
-10 + (-9) = -19 or -29 + 10 = -19
Step-by-step explanation:
For the first question, divide 34 * 2 and you get 17, DOUBLE CHECK YOUR ANSWER!
17*2 = 34 ✔
For the second, mess around with a few numbers add +10 and -29, COUNT DOWN from 10 and -29.
since + + + = + then - + - = -
if 10+9=19 then do the same with -
-10 + (-9) =-19

Write the equation of the line in Slope-Intercept form.
Answer:
Y=-2/3+4
Step-by-step explanation:
The slope of the equation can be solved with
2-4/3-0 y2-y1 divide by x2-x1 which gives 3/2 and the y intercept the point at which the slope hits the y intercept which is 4. Also the slope is negative as it’s pointed downwards.
Getting the slope:
m=[tex](y_1 - y_2 )/(x_1 - x_2)[/tex]
Using this formula, the slope is calculated to be -2/3
To find intercept, plug in a point value into equation and solve.
Intercept = 4
Total equation: y=-2/3x + 4
