Therefore, the vertical component of the force exerted on the block by the floor is equal to the normal force (N).

To determine the vertical component of the force exerted on the block by the floor, we need to consider the forces acting on the block. In this case, since the block is being pulled horizontally, the main forces to consider are the gravitational force (mg) acting vertically downward and the normal force (N) exerted by the floor perpendicular to the surface.

Since the block is on a rough horizontal floor and being pulled horizontally, there is a frictional force (f) opposing the motion. The frictional force acts parallel to the surface and in the opposite direction to the applied force. The vertical component of the force exerted by the floor is equal to the normal force (N). The normal force balances the downward force due to gravity (mg) to keep the block in equilibrium vertically.

Explanation:

This is a 45-45-90 triangle, aka an isosceles right triangle. Any triangle of this type will always have each leg congruent to one another, and the hypotenuse is sqrt(2) times that of the leg length.

The hypotenuse is 7*sqrt(2) units long, meaning each leg must be 7 units long.

We can use the pythagorean theorem to solve \(x^2+x^2 = \left(7\sqrt{2}\right)^2\) and you should find the positive solution is x = 7. Ignore the negative x solution.

Answer:

7

Step-by-step explanation:

In a 45 -45 90 triangle, the hypotenuse = leg\(\sqrt{2}\)

In the triangle, the hypotenuse is given because it is the side opposite the right angle.

hypotenuse = leg\(\sqrt{2}\)  

     7 \(\sqrt{2}\) = leg \(\sqrt{2}\)       Solve for the leg

   \(\frac{7\sqrt{2} }{\sqrt{2} } =\frac{leg\sqrt{2} }{\sqrt{2} }\)

        7 = leg          legs are equal in a 45- 45- 90 triangle

Ascending order is a method of arranging numbers from smallest value to largest value. The order goes from left to right. Ascending order is also sometimes named as increasing order. For example, a set of natural numbers are in ascending order, such as 1 < 2 < 3 < 4 < 5 < 6 < 7 < 8… and so on.

To order the numbers from least to greatest, we need to arrange them in ascending order.

Given the numbers: -2, 4, 23, -6, 83

Step 1: Start by comparing the smallest two numbers. In this case, we have -2 and -6. Since -6 is smaller than -2, we can place it first in the order:

-6

Step 2: Now, we compare the remaining numbers: -2, 4, 23, 83.

-2 is the next smallest number. So, we add it to the order:

-6, -2

Step 3: Next, we compare the remaining numbers: 4, 23, 83.

4 is smaller than 23 and 83. So, we add it next:

-6, -2, 4

Step 4: Finally, we compare the remaining numbers: 23, 83.

Since 23 is smaller than 83, we add it before 83:

-6, -2, 4, 23, 83

So, the numbers in ascending order from least to greatest are: -6, -2, 4, 23, 83.

Answer:

40 DEGREES COUNTERCLOCKWISE

140 DEGREES CLOCKWISE

Step-by-step explanation:

To get from frame one to frame two you can either rotate the object in a clockwise or anticlockwise direction.

We can use the edges of the rectangle to monitor the degree with which it is rotated.

If we rotate in a clockwise direction, it means that we are rotating from the left to the right; that is in the direction of the clock. If we are turning this way, we would have to turn the rectangle through 140 degrees to get it into frame 2's position

If we are rotating in the anticlockwise direction (against the direction of the clock) we are turning it from the right to the left. We will be turning it by only 40 degrees to get it into frame 2's position

Answer:

w = 7 feet

Step-by-step explanation:

Volume of a rectangle prism = length × width × height

Length = 7 feet

Width = ?

Height = 3 1/4 feet

Volume = 159 1/4 cubic feet

Volume of a rectangle prism = length × width × height

159 1/4 = 7 × w × 3 1/4

637/4 = 7 × w × 13/4

637/4 = 7 × 13/4 × w

637/4 = 91/4w

w = 637/4 ÷ 91/4

= 637/4 × 4/91

= 637*4 / 4*91

= 2548 / 364

w = 7 feet

Answer:

\(5x+6y=22.50\\x+9y=24.75\)

Step-by-step explanation:

Cost of 5 drinks and 6 snacks = $22.50

Cost of 1 drink and 9 snacks = $24.75

Each drink costs the same and each snack costs the same.

Let cost of each drink = $\(x\)

Let cost of each snack = $\(y\)

As per the question, writing the system of equations:

\(5x+6y=22.50 ...... (1)\\x+9y=24.75 ...... (2)\)

Let us use elimination method, to find the cost of each drink and cost of each snack.

Multiplying equation (2) by 5 and then subtracting equation (1) from it:

\(45y - 6y = 123.75 - 22.5 \\\Rightarrow 39y = 101.25\\\Rightarrow y \approx \$2.60\)

Using equation (1):

\(5x+2.6 \times 6 = 22.5\\\Rightarrow 5x = 22.5 - 15.6\\\Rightarrow 5x = 6.9\\\Rightarrow x = \$1.38\)

Cost of each drink = $1.38

Cost of each snack = $2.60

If the assumptions for the large sample confidence interval for the population proportion are not met, adjustments can be made is-

D) Nothing can be done.

If the assumptions for the large sample confidence interval for the population proportion are not met, adjustments can be made to improve the accuracy of the confidence interval calculation.

In this case, there are three potential adjustments mentioned:

A) Use phat (X+1)/(N+3) instead.

B) Add enough successes to make there be 15 successes and 15 failures.

C) Use phat = (X+2)/(N+4) instead.

These adjustments are made to address the limitations or violations of assumptions. Let's discuss each option:

A) Use phat (X+1)/(N+3) instead:

This adjustment incorporates an adjustment factor to the usual formula for the sample proportion (phat). By adding 1 to both the numerator (number of successes) and the denominator (sample size), it attempts to mitigate potential issues related to extreme values.

B) Add enough successes to make there be 15 successes and 15 failures:

This adjustment involves artificially modifying the data to ensure a balanced number of successes and failures. By doing so, it aims to satisfy the assumption of a sufficiently large sample size and approximate a normal distribution. However, it should be noted that altering the data in this manner may introduce biases and may not be statistically appropriate in certain cases.

C) Use phat = (X+2)/(N+4) instead:

Similar to option A, this adjustment adds a correction factor to the usual formula for the sample proportion. By adding 2 to both the numerator and denominator, it aims to address potential issues associated with small sample sizes or extreme values.

D) Nothing can be done:

This option suggests that no adjustments can be made when the assumptions for the large sample confidence interval for the population proportion are not met.

Therefore, if the assumptions for the large sample confidence interval for the population proportion are not met, adjustments can be made is-

Answer:

The correct answer is B. 20,000

Step-by-step explanation:

To determine the man's total monthly salary, we can set up a simple equation using the given information. Let's denote the total monthly salary as "x."

According to the information provided, 33% of the man's monthly salary is equal to Birr 6600. We can express this relationship mathematically as:

0.33x = 6600

To solve for "x," we need to isolate it on one side of the equation. We can do this by dividing both sides of the equation by 0.33:

x = 6600 / 0.33

Evaluating the right side of the equation gives:

x ≈ 20,000

Therefore, the man's total monthly salary is approximately Birr 20,000.

Hence, the correct answer is B. 20,000.

Answer: 4x^3-38x^2+88x

Step-by-step explanation:

The volume of the box in standard form is 4x³ - 38x² + 88x

Since Janelle cuts a square of side length x out of each corner of the cardstock, we have a length x + x = 2x cut out of each dimension of the cardstock.

Since the dimensions of the cardstock are 8 inches by 11 inches, cutting out a length of 2x inches from each dimension to produce the length, L and width, w of the open box, we have the length of the open box, L = 8 -2x and the width of the open box, W = 11 - 2x.

Since the height of the open box is the length x of the square cut out of each corner, and the open box is a rectangular box,

So, the volume of the box is

V = LWx

Substituting the values of the variables into the equation, we have

V = LWx

V = (8 - 2x)(11 - 2x)x

Expanding the brackets, we have

V = (88 - 16x - 22x + 4x²)x

V = (88 - 38x + 4x²)x

V = 88x - 38x² + 4x³

Re-arranging, we have

V = 4x³ - 38x² + 88x

So, the volume of the box in standard form is 4x³ - 38x² + 88x
