Answer:

1 hour and 30 minutes

Step-by-step explanation:

Mary spend 3 hours at the gym

Sandy spend 15 minutes less

180 - 15 = 165
Sandy spent 165 minutes at the gym (2 hours and 45 minutes)

Judy spent one hour and 15 minutes less than Sandy

165 - 75 = 90

90= 1 hour 30 min

Answer:

(1.3^9)/(1.3^3)= Last Column: (1.3)^6

(-5/6)^2= First Column: -5^2/6^2

(-5/6)^1: Third Column: -5/6

(1.3)^0: Second Column: 1

Answer:

first row last column, second row first column, third row third column, last row second column

Step-by-step explanation:

first row last column: doing division w/ exponents means you have to subtract the exponents. 9-3=6 and since they have the same base, you don't have to do anything with it, so the answer is the last column.

second row first column: properties show that the square of -5/6 is equal to -5^2/6^2 or 5^2/-6^2. therefore, the answer is the first column.

third row third column: anything to the power of one is itself.

last row second column: anything to the power of zero is one.

Answer:

Step-by-step explanation:

To make the race close, the length of the race should be 450 meters.

Here's the reasoning behind the answer:

Let's first calculate how long it would take for Emile to catch up to Henri, assuming Henri starts 45 meters ahead.

The time it takes Emile to cover the same 45-meter distance is 45/2.5 = 18 seconds.

During this time, Henri would have walked a distance of 1 x 18 = 18 meters.

So, after 18 seconds, Emile will have caught up to Henri and will be 27 meters ahead of him (45 - 18 = 27).

To make the race close, we want Henri to finish just a split second before Emile. So, we can assume that Henri will finish the race just as Emile catches up to him.

Let's call the total distance of the race "d."

So, Henri will walk d meters, while Emile will walk d + 27 meters (the 27 meters is the distance Emile has to walk after catching up to Henri).

We can set up an equation to solve for d:

d/1 = (d + 27)/2.5

Solving for d, we get:

d = 450

So, the race should be 450 meters long for Henri to win in a close race.

Step-by-step explanation:

The domain of the notation \(s(x) = \sum\limits^{\infty}_{n=1} n^{-x}\) is the set of all real values

The sum notation is given as:

\(s(x) = \sum\limits^{\infty}_{n=1} n^{-x}\)

From the above notation, the smallest value of n is 1.

This means that the variable x can take any real value as it value

Hence, the domain of the notation \(s(x) = \sum\limits^{\infty}_{n=1} n^{-x}\) is the set of all real values

Answer:

Step-by-step explanation:

The cube root of 64 is the number which when multiplied by itself three times gives the product as 64. Since 64 can be expressed as 2 × 2 × 2 × 2 × 2 × 2. Therefore, the cube root of 64 = ∛(2 × 2 × 2 × 2 × 2 × 2) = 4.

The cube root of 64 is 4.

Before solving the question, let's understand the concept of cube root.

The cube root of a number is the value obtained by multiplying it by itself three times or thrice. When we multiply 3 by itself three times, we get 3 x 3 x 3 = 27 = 3³, so the cube root of 27 is 3. Thus, we can say that the cube root gives a value that is basically cubed.

The cube root is denoted by ∛

Now, we will find the cube root of 64.

Firstly, we have to find factor 64.

64 = 2 × 2 × 2 × 2 × 2 × 2.

64 = ∛4³

64 = 4

Therefore, the cube root of 64 is 4.

Answer:

Step-by-step explanation:Situation A: The hang glider descended 33.57 feet and again ascended 14.98. So 33.57 - 14.98 = 18.58. So now the hang glider is at 18.58 feet

Situation B: Initially they gained 7 2/5 yards and then lost 3/5 yards.

7 2/5 yards can be written as 37/5. As they lost 3/5 yards, 37/5 - 3/5 = 34/5. So the remaining yards are 34/5 yards.

Situation C: Hiker walked 3 1/6 miles and then 2 1/2 miles. So the total distance is 3 1/6 + 2 1/2 = 5 4/6 miles.

Situation D: Total amount earned is $23.66 + $15.84 = $39.5.

Answer:

The translation used to create the image from polygon ABCD to polygon A' B' C' D' is 5 units down.

Step-by-step explanation:

You can see this by observing that all of the y-coordinates in A' B' C' D' are 5 units less than their corresponding y-coordinates in ABCD. Specifically, the y-coordinates of the vertices in ABCD are (-1, -5, -5, -1), and the y-coordinates of the vertices in A' B' C' D' are (-6, -10, -10, -6).

Therefore, the vertical shift or translation used to create the image is 5 units down.

Answer:

5 units down.

Step-by-step explanation:

To solve this question, we need to compare the coordinates of the corresponding vertices of the two polygons and see how they change. A translation is a type of transformation that slides a figure by a certain distance and direction without changing its size or shape. The rule of a translation can be written as (x, y) -> (x + h, y + k), where h and k are the horizontal and vertical shifts, we can see that:

We can see that all the vertices have the same change in their coordinates: x stays the same and y decreases by 5. This means that the translation used to create the image is 5 units down. The rule of this translation can be written as (x, y) -> (x, y - 5). Therefore, the answer is 5 units down.

Answer:

For A: The first function has a greater ROC

For B: The first function has a negative slope

Step-by-step explanation:

Explication for A:

We already know that the R.O.C. (slope) is 2 for the first function, so all we need to do is substitute the values in the table into the following formula: y2-y1/x2-x1

after substituting: (-3-(-6))/(0-(-1))

simplify 3/1=3, since the ROC is 3, the second equation has a greater ROC than the first

Explanation for B:

The first function described is f(x)=20-3.5x

This is because the y intercept is the starting point, or how much money she has in the gift card. She spends 3.5 dollars per week, so we add a variable to represent the number of weeks, and its negative since she is spending, not earning. We also know that the slope is negative since y is decreasing as x is increasing, on the table.

The second function described is c(m)=5x+10

This is because the equation represents the total cost of renting a calculator, so both terms are positive.
