Answer:

q+4 + d-3 + n ; first

Step-by-step explanation:

first :q quarter d dimes n nickels

then: q+4 quarter d dimes n nickels

then: q+4 quarter d-3 dimes n nickels

so you have q+4 + d-3 + n

first is the only option that has division the other involve subtraction

Answer:

The last one

Step-by-step explanation:

When u divide if the divisor has a decimal u move the decimal to the right so it becomes a whole number u also move the decimal who is inside the division to the right as well. So it’s 793.1 divided by 11

well, Yasin is correct, the exterior angles are all 36° each, however "g" is including more than just that, Check the picture below.

Answer: The answer is 722.

Step-by-step explanation:

1,721 - 999 = 722.

So, 999 + 722 = 1,721.

Answer: 722

Step-by-step explanation:

All you do is subtract 999, from 1,721. Super easy :)

Answer:

If the higher power is in the denominator, put the difference in the denominator and vice versa, this will help avoid negative exponents and a repeat of step 3. Step 6: Raise each coefficient (or number) to the appropriate power and then simplify or reduce any remaining fractions. Step 1: Apply the Zero-Exponent Rule.

Answer:no

Step-by-step explanation:

Because u can not subtract a denominator from numerator u must subtract the denominator by the denominator

Answer:

12

Step-by-step explanation:

15 + (-3) = 12

you could also write it as 15 - 3 = 12

Answer: 12

Explanation:

15 is in +
-3 is in -

So, - and + = -

Write the Equation
15 - (-3)

(Do normal subtraction)
= 12 (which sign do we use?)

15 > -3

greater number sigh is + so,

+12 or 12 is the answer

Answer:

B. 960 units²

Step-by-step explanation:

find the area of each surface

the area for a triangle is 1/2(b×h), and there are q triangles here, so just do b×h

y×h = 24×16 = 384

next, find the area of the bottom and sides of the prism.

x×z = 20×9 = 180

180 × 2 = 360

z×y = 9×24 = 216

finally, add all of those together

384+360+216 = 960 units²

Answer:

\(f^{-1}\left(f(576)\right)=\boxed{576}\)

\(f^{-1}(-7)+f(-7)=\boxed{13}\)

Step-by-step explanation:

The inverse of an invertible function with the domain of all real numbers is obtained by reflecting the original function across the line y = x, which swaps the input and output values of the function. Therefore, (x, y) → (y, x).

Given table:

\(\begin{array}{lrrrrrr}\vphantom{\dfrac12}x&-7&11&-13&6&5&-9\\\cline{1-7}\vphantom{\dfrac12}f(x)&7&12&8&-7&13&5\end{array}\)

Inverse function:

\(\begin{array}{lrrrrrr}\vphantom{\dfrac12}x&7&12&8&-7&13&5\\\cline{1-7}\vphantom{\dfrac12}f^{-1}(x)&-7&11&-13&6&5&-9\end{array}\)

If we have a function f(x), the inverse function is denoted as f⁻¹(x), and it has the property that f⁻¹(f(x)) = x for all valid inputs x in the domain of f(x).

Therefore:

\(\large\boxed{f^{-1}\left(f(576)\right)=576}\)

The value of f(-7) is the value of f(x) when x = -7. Therefore, reading from the original table, f(-7) = 7.

The value of f⁻¹(-7) is the value of f⁻¹(x) when x = -7. Therefore, reading from the inverse function table, f⁻¹(-7) = 6.

Therefore:

\(\large\boxed{\begin{aligned}f^{-1}(-7)+f(-7)&=6+7\\&=13\end{aligned}}\)

Step-by-step explanation:

A factory sells backpacks for $40.00 each. The cost to make 1 backpack is $10.00. In addition to the costs of making backpacks, the factory has operating expenses of $12,000 per week. The factory's goal is to make a profit of at least $980 each week. Which inequality represents the number of backpacks, x, that need to be sold each week for the factory to meet this goal? How many backpacks must the factory sell to meet its weekly goal?

Drag the inequality that represents this situation and drag the correct statement into the proper boxes below.

Answer: This situation cannot be true for any positive value of x. The valid range would be 0 < x < 4. If the x is less than 4, the perimeter of triangle 1 is always greater than triangle 2.

Explanation: We need to add up the lengths of the sides for obtaining the perimeters first.

Triangle 1: 5x + 57

Triangle 2: 11x + 33

Then, we need to build up an inequality for the case which the perimeter of triangle 1 is always greater than triangle 2.

This means => 5x + 57 > 11x + 33

If we write "x" values on one side:

24 > 6x

Then dividing by 6 for both sides:

4 > x

This means that a positive value of x should be less than 4 for this particular situation.

Step-by-step explanation:

1) there are 12 possible lunch options. 2) the probability of having any meal with no cookie is 1/2 or 0.5.

1) Number of possible lunch options:

To determine the number of possible lunch options, we need to consider the choices for each component of the lunch.

- Sandwich: There are 3 options (turkey, roast beef, or bologna).

- Fruit: There are 2 options (orange or apple).

- Dessert: There are 2 options (cookie or muffin).

Using the counting principle, we multiply the number of options for each component together:

Number of possible lunch options = 3 (sandwich options) × 2 (fruit options) × 2 (dessert options) = 12.

Therefore, there are 12 possible lunch options.

2) Let's examine the favorable outcomes for each component:

- Sandwich: There are still 3 options (turkey, roast beef, or bologna).

- Fruit: There are 2 options (orange or apple).

- Dessert: There is 1 option (muffin, as we want to exclude cookies).

Using the counting principle, we multiply the number of options for each component together:

Number of favorable outcomes (no cookie) = 3 (sandwich options) × 2 (fruit options) × 1 (muffin option) = 6.

The total number of possible outcomes is still 12 (as calculated in the previous step).

Therefore, the probability of having any meal with no cookie is:

P(No cookie) = Number of favorable outcomes / Total number of possible outcomes = 6 / 12 = 1/2 or 0.5.

Hence, the probability of having any meal with no cookie is 1/2 or 0.5.

Answer: A and c.

Step-by-step explanation: No matter the arrangement, those seem to be the same.  The first option is a reflection of the y axis and it's still the same shape. B's shape changes, which doesn't make it congruent.  The option after that is a rotation, and once again, it hasn't changed its congruence.  The last option has different shapes, so those aren't congruent either.

Let me know if it's right! :)
