a company sells tablet computers and phones. it sells a total of 150 items this month. the number of tablets sold is half of the number of phones sold. the company makes profit of $300 on each tablet and $400 on each phone. what is the profit the company makes this month?
Answer:
$52500 this month
Step-by-step explanation:
150 divided by 2 = 75
$75 x 300 = 22500
$75 x $400 = 30000

A circle is dilated by a scale factor of 1.5 to create a new circle. The area of the new circle is 1.5 times the area of the original circle.
True or false??
Given:
The given statement is "A circle is dilated by a scale factor of 1.5 to create a new circle. The area of the new circle is 1.5 times the area of the original circle."
To find:
Whether the given statement in true or false.
Solution:
Area of circle is
[tex]A=\pi r^2[/tex]
Where, r is the radius of the circle.
Let [tex]r_1[/tex] be the radius of the original circle. So, the area of the circle is
[tex]A_1=\pi (r_1)^2[/tex]
The circle is dilated by a scale factor of 1.5 to create a new circle. So, the radius of the new circle is:
[tex]r_2=1.5r_1[/tex]
The area of the new circle is
[tex]A_2=\pi (r_2)^2[/tex]
[tex]A_2=\pi (1.5r_1)^2[/tex]
[tex]A_2=2.25\pi (r_1)^2[/tex]
[tex]A_2=2.25A_1[/tex]
The area of the new circle is 2.25 times the area of the original circle.
Therefore, the given statement is false.
Bob wants to order some books from an online bookstore. Each book costs 16.50 and shipping for the entire order is a flat rate of 25.03. Bob can spend no more than 78.00
Answer:
x ≤ 3.210
Bib can buy no more Than 3 books
Step-by-step explanation:
Given that:
Cost per book = 16.50
Total shipping = 25.03
Total budgeted amount = 78
The number of books, x that can be ordered can be represented by the inequality :
16.50x + 25.03 ≤ 78
16.50x ≤ 78 - 25.03
16.50x ≤ 52.97
x ≤ 52.97 / 16.50
x ≤ 3.210
Bib can buy no more Than 3 books

how many factors of 10 are in 10 of the third power?
Answer:2 times 5 equals 10
Step-by-step explanation:
"The factors of 10 are 1, 2, 5, and 10. You can also look at this the other way around: if you can multiply two whole numbers to create a third number, those two numbers are factors of the third. 2 x 5 = 10, so 2 and 5 are factors of 10." From ww.infoplease.com great resource
The required factor of 10 in 10 of the third power is 3.
What are the factors?A number or algebraic expression that evenly divides another number or expression—i.e., leaves no remainder—is referred to as a factor.
Here,
10 of the third power = 10³
10³ = 10×10×10
The expression 10×10×10 has 3, 10's
Thus, the required factor of 10 in 10 of the third power is 3.

Problem ID: PRABEE2G
Solve:
14x+y=7
Write your answer in the following format:
with no spaces.
Answer:
x = 7/10; y = 21/5
Step-by-step explanation:
y = 6x
4x + y = 7
Since the first equation is already solved for y, we can easily use the substitution method. We substitute 6x for y in the second equation and solve for x.
4x + y = 7
4x + 6x = 7
10x = 7
x = 7/10
Now we use the first equation and substitute 7/10 for x and solve for y.
y = 6x
y = 6 * 7/10
y = 42/10
y = 21/5
Answer: x = 7/10; y = 21/5

Step-by-step explanation:
Following are the calculation to the given coordinates:

The y-axis reflection:Modify its abscissa's sign, i.e., the x-coordinate.Keep this ordinate, which would be the y-coordinate.[tex]\to[/tex] (-2, 5) is the image (-2, -5).
Also, as a result, the coordinates of point T' after the Ry-axis are as follows: (2, 5).
Whenever a point is reflected throughout the x-axis, the x-coordinate is unchanged, but the "y-coordinate" is assumed to be the additional inversion.[tex]\to[/tex] (-2, 5) is the image (-2, -5).
