A picture is 7 inches wide and 9 inches long. A photographer enlarges it so it is 31.5 inches wide and 40.5 inches long. What scale factor was used to enlarge the picture?
9/77
7/9
31.5/7
7/31.5

Answer:

69

Step-by-step explanation:

The central angle is twice the inscribed angle. So the angle that is behind the one equal to 2x is equal to x. We know that the opposite angles in a circle add up to 180. Therefore, we can solve for x:

[tex]x + x + 42 = 180$^{\circ}$\\\\2x = 180$^{\circ}$ - 42$^{\circ}$\\\\2x = 138$^{\circ}$\\\\x = 69$^{\circ}$[/tex]

The container holds more than 3 cups of sugar, since it holds 3 times the amount used in the recipe.

To calculate the amount of sugar in the container, we need to first determine the amount used in the recipe. The recipe calls for 2 1/3 cups of sugar. This can be converted to a decimal by dividing by 3, resulting in 2.333 cups of sugar used in the recipe. Now that we know the amount used, we can calculate the amount the container holds.

1. 2 1/3 cups = 2.33 cups

2. 3 x 2.33 cups = 6.99 cups

The container holds 3 times the amount used, so we can multiply 2.333 cups by 3, resulting in 6.999 cups of sugar in the container. This is more than 3 cups of sugar, so the container holds more than 3 cups of sugar.

The logarithm of a number with respect to a base is the exponent to which the base must be raised to produce that number. In other words, log_b(x) = y means b^y = x.

To find log_7(x), we can use the change of base formula which is log_b(x) = log_c(x) / log_c(b).

So you can use the logarithm of base 10 (common logarithm) or base e (natural logarithm) and use the above formula to find log7

So for example, log7(49) = log10(49) / log10(7) or log7(49) = ln(49) / ln(7)

You can use a calculator or a logarithm table to find the result.

Step-by-step explanation:

Answer: List 2

Mark the midpoint between 1/6 and 1/2 (see diagram below)

======================================================

Explanation:

There are 3 meats (ham, turkey, bologna) and 2 vegetables (carrots, celery).

This gives 3*2 = 6 different combos of meat plus a vegetable. This is where we can only pick one of each type.

The 6 different combos are shown in  list 2  

List 1 is not correct because you can choose one vegetable only, and not have both.

----------

Look through list 2 and circle the options that say "ham, carrots" and "turkey, carrots". There are 2 items that are circled. This is out of 6 total.

We arrive at the probability 2/6 = 1/3

The fraction 2/6, aka 1/3, is located at the halfway point between 1/6 and 1/2. This is because 1/6+1/2 = 1/6+3/6 = 4/6, which divides in half to get 2/6.

See the diagram below.

the height of the stamp is 2/5in.

What is a fraction?

If the numerator is bigger, it is referred to as an improper fraction and can also be expressed as a mixed number, which is a whole-number quotient with a proper-fraction remainder.

Any fraction can be expressed in decimal form by dividing it by its denominator. One or more digits may continue to repeat indefinitely or the result may come to a stop at some point.

Given that stamp of Height is 3in with 4 1/2 in width.

So 9/2 of width = 3 Height

1 of width = 3/(9/2) Height

So for 3/5 in wide = 3/5* 3/(9/2) = 2/5in

Hence the height of the stamp is 2/5in.

Step-by-step explanation:

Given inequality:

[tex]\dfrac{1}{5}(m-5)\leq \dfrac{1}{10}(m-20)[/tex]

To solve the inequality, multiply both sides by 10:

[tex]\implies \dfrac{10}{5}(m-5)\leq \dfrac{10}{10}(m-20)[/tex]

[tex]\implies2(m-5)\leq m-20[/tex]

There are 4 rows of Soprano. The concept of algebraic manipulation is used to solve the problem.

Given the information that there are 64 fingers in total and 8 fingers in each row of the Tenor, I was able to determine that there are 32 fingers in the Tenor rows by multiplying 8 fingers/row x 4 rows.

Then, We subtracted the number of fingers in the Tenor rows (32 fingers) from the total number of fingers (64 fingers) to find the number of fingers in the Soprano rows, which is also 32 fingers.

Finally, We divided the number of fingers in the Soprano rows by the number of fingers per row (8 fingers/row) to find the number of rows of Soprano, which is 4 rows.

If there are 64 fingers in total and 8 fingers in each row of the Tenor, then there are 8 fingers / row x 4 rows = 32 fingers in the Tenor rows.

Since there are 64 fingers in total and 32 fingers in the Tenor rows, then there are 64 fingers - 32 fingers = 32 fingers in the Soprano rows.

Therefore, there are 32 fingers / 8 fingers/row = 4 rows of Soprano.

(a) The net force equation on q1 is 10.6N towards q2. (b) The acceleration of q1 would be 6.8x10^7m/s^2.

a) The Coulomb's law equation for the force between two charges q1 and q2 is given by:

F = k(q1q2)/r2

Where k is the Coulomb's constant and r is the distance between the two charges.

Using this equation, the force on q1 due to q2 can be calculated as:

F12 = (8.99x109 N m2/C2)(8.00x10-6C)(-5.00x10-6C)/(1.00m)2

F12 = -44.8x10-6 N

Similarly, the force on q1 due to q3 can be calculated as:

F13 = (8.99x109 N m2/C2)(8.00x10-6C)(5.00x10-6C)/(2.00m)2

F13 = 55.2x10-6 N

The net force on q1 can be calculated as the vector sum of F12 and F13:

F1 = F12 + F13

F1 = 10.6N towards q2

b) The acceleration of q1 can be calculated using Newton's second law of motion:

F = ma

a = F/m

Where m is the mass of q1.

Therefore, the acceleration of q1 can be calculated as:
