Let be the number of pennies, be the number of nickels, and be the number of dimes that Vern has. The given ratios tell us that and Therefore, so we haveTo turn this into a ratio of integers, we multiply every part of the ratio by Doing this, we see that Therefore, we can think of Vern's collection as consisting of several groups, each of which contains pennies, nickels, and dimes. Let be the number of such groups of coins that Vern has. Then Vern has pennies, nickels, and dimes. Since a penny is worth cent, a nickel is worth cents, and a dime is worth cents, the total worth of Vern's coins in cents is However, we know Vern has or cents, so we can write an equation:Simplifying the left-hand side, we get Dividing both sides by we get This tells us that Vern has groups of coins, for a total of coins.

what does relatively prime mean in math?
Answer:
When two numbers have no common factors other than 1.
Step-by-step explanation:
In other words there is no value that you could divide them both by exactly (without any remainder).
21 and 22 are relatively prime:
• The factors of 21 are 1, 3, 7 and 21
• The factors of 22 are 1, 2, 11 and 22
(the only common factor is 1)
But 21 and 24 are NOT relatively prime:
• The factors of 21 are 1, 3, 7 and 21
• The factors of 24 are 1, 2, 3, 4, 6, 8, 12 and 24
(the common factors are 1 AND 3)
Relatively Prime is also called "coprime" or "mutually prime".
Here we see that 12 and 16 are NOT relatively prime
List all the angle measures from least to greatest.
From the three triangles
Answer:
40°, 43°, 60°
Step-by-step explanation:
In each triangle, you are given the measures of two angles. Subtract those two measures from 180° to find the measure of the third angle.
Triangle A:
c = 180° - 90° - 50°
c = 40°
Triangle B:
c = 180° - 112° - 25°
c = 43°
Triangle C:
c = 180° - 70° - 50°
c = 60°

Answer:
x = 12
Step-by-step explanation:
First:
[tex]27=9*3=3*3*3=3^3[/tex]
If you rewrite the 27 into base 3 like that:
[tex]3^{5x}=3^{(3)\times(2x-4)[/tex]
Now that both sides have the same base, you can cancel them out. This is the simplest example of that I can think of:
[tex]2^x=2^x[/tex]
Here, the exponent obviously has to be equal for this to be true, right? The exponents do have to be equal, so you can drop the bases completely:
[tex]x=x[/tex]
Same for the problem we have above. It's a base 3 on both sides, and for them to be equal, the exponents also have to be equal.
[tex]3^{5x}=3^{(3)\times(2x-4)}\\5x=(3)\times(2x-4)\\5x=3(2x-4)[/tex]
Now, you can simply solve for x.
[tex]5x=6x-12\\-1x=-12\\x=12[/tex]

You must answer all questions above in order to submit.
attempt 1 out of 2
Help me solve this PLEASE?
Work Shown:
1 pound = 16 ounces
3 pounds = 48 ounces (multiply both sides by 3)
Based on that, we can then say,
(750 calories)/(10 ounces) = (x calories)/(48 ounces)
750/10 = x/48
75 = x/48
x/48 = 75
x = 48*75
x = 3600

Write them as ordered pairs in the form (x-coordinate, y-coordinate). Starting from the origin, explain how to plot the three equivalent ratios on a coordinate grid. (10 points)
Answer:
(1, 3), (2, 6), (3, 9)
Step-by-step explanation:
Dividing the first given ratio by 7 gives ...
7/7 : 21/7 = 1 : 3
Multiplying this by 2 and 3 gives the other ratios you want.
= 2(1) : 2(3) = 2 : 6
= 3(1) : 3(3) = 3 : 9
The equivalent ratios are (1, 3), (2, 6), (3, 9).

Suppose $\frac{1}{2} + \frac{1}{3} + \ldots +\frac{1}{x} > 1\frac{1}{2}$. What is the smallest possible value for $x$?
The smallest possible value of x is the value less than 2/3
Given the series [tex]$\frac{1}{2} + \frac{1}{3} + \ldots +\frac{1}{x} > 1\frac{1}{2}$[/tex]
We need to find the smallest possible value of x as shown:
[tex]\frac{1}{x} > 1\frac{1}{2}\\ \frac{1}{x} > \frac{3}{2}\\[/tex]
Reciprocate both sides
[tex]x < \frac{2}{3}[/tex]
Hence the smallest possible value of x is the value less than 2/3

The value of x is 5. The value of y is 8.66.
The image attached is that of a right triangle. In order to determine the value of x and y, SOHCAHTOA would be used. x is he opposite side and y in the adjacent side to the angle 30 degrees.
Sin 30 = opposite / hypotenuse
0.5 = x / 10
x = 5
Cos 30 = adjacent / hypotenuse
0.8660 = y / 10
y = 8.66

What is the median of the following data values?
10, 11, 12, 15, 19, 24, 27, 29, 33, 38
Answer:
21.5
Step-by-step explanation:
Make sure they are in order.
A median is basically (or literally) the number in the middle of the data set.
In this case, it is 19 and 24. To get the middle number, you have to:
Add the two numbers and divide them by 2.
19 + 24 = 43
43/2 = 21.5
