Answer:

1/2

Step-by-step explanation:

Let's say the number is 1.5

1.5 = 1 + 0.5

(1.5 = 1 + 0.5)*10 ==> multiply by 10 to remove decimals

15 = 10 + 5

5 is half of 10

Hence, 0.5 is half of 1 ==> 0.5 = 1/2

Step-by-step explanation:

The hotel charge in the first city before tax was $6000 and the hotel charge in the second city before tax was $7500.

Let x be the hotel charge before tax in the first city, and y be the hotel charge before tax in the second city. Then we have:
y = x + 1500   (the hotel charge before tax in the second city was $1500 higher than in the first)
0.075x + 0.05y = 825   (the total hotel tax paid for the two cities was $825)
We can use the first equation to solve for y in terms of x:
y = x + 1500
Then we can substitute this expression for y into the second equation:
0.075x + 0.05(x + 1500) = 825
Simplifying this equation, we get:
0.075x + 0.05x + 75 = 825
0.125x = 750
x = 6000
So the hotel charge before tax in the first city was $6000. Using the first equation, we can find the hotel charge before tax in the second city:
y = x + 1500
y = 6000 + 1500
y = 7500
So the hotel charge before tax in the second city was $7500.
Therefore, the answer is: The hotel charge in the first city before tax was $6000 and the hotel charge in the second city before tax was $7500.

Answer:

142 square meters

Step-by-step explanation:

To find the Surface Area of a Cylinder you have to use the formula \(A= 2\pi rh+2\pi r^2\)

Plug in the radius, height, and pi to get

\(A=(2*3.14*2.6*6.1)+(2*3.14*2.6^2)\\A= (99.6008)+(42.4528)\\A= 142.0536\\\)

You can round the answer to 142

Step-by-step explanation:

let's break it down first

\( 4x + 8 < 20 \)

\(4x < 20 - 8\)

\(4x < 12\)

Divide both sides by the coefficient of x which is 4

\(4x \div 4 < 12 \div 4\)

\(x < 3\)

\(4 < x < 3\)

4 is less than x which is greater than 3

x = 4,5,6,7,8,......

since 4 is less than x, x cannot be 4

so x could be 5,6,7,8,9,.......

Answer:

C

Step-by-step explanation:

The term range is used when looking for y.

This automatically eliminates the possibility of B and D.

Since y applies only to the vertical aspect of the graph, we can ignore all of the horizontal information (time minutes)

Looking at distance, the bug's lowest point was at 100cm and at its highest point at 400cm

This means the minimum is 100 and maximum is 400

In other words:

100 <= y <= 400

Answer:

C) 100 ≤ y ≤ 400

When we are talking about range, we are talking about y values, so B is disqualified.

When determining range you want the lowest & highest y values.

On this graph the lowest value of y is 100 (seen between 5 and 6 seconds).

The highest value of y is 400 (seen at 8 seconds).

Therefore, 100 ≤ y ≤ 400.

a). The number of scores which are expected to be lower than 18.31 is; 16 scores.

b). The number of scorers that are expected to be below 32.38 is; 98 scores.

As evident in the task content; the 100 ACT scores in discuss are normally distributed, hence, all peculiar characteristics of a normal distribution apply.

First, since the mean is given as; 23 and the standard deviation is; 4.69.

By observation; 23 - 4.69 = 18.31 and

23 + 4.69 + 4.69 = 32.38.

a). Since the percentage of data values which fall below one standard deviation below the mean is; 15.9% which is approximately; 16%.

Therefore, the number of scores below the 18.31 score is; 16% of 100 = 16 scores.

b). Also, since the score; 32.38 is 2 standard deviations above the mean, and it follows from a normal distribution that the percentage of data values below such data value is; 97.7% which is approximately 98%.

Therefore, the number of scores which are expected to be below 32.38 is; 98% of 100 = 98.

The area of the land is 3600 + 60n.

What is area?

Area is a mathematical concept that expresses the size of a region on a plane or curved surface. The area of an open surface or the boundary of a three-dimensional object is referred to as the surface area, whereas the area of a plane region or plane area refers to the area of a shape or planar lamina.

Given: A contractor is building a new subdivision.

A rectangular piece of land for a new house and yard is 60 feet wide.

The length of the land is longer than the width by a distance of n feet.

So, width = 60 feet

and length = 60 + n feet

Since, the area of rectangular piece of land (A)

Area = length x width

Area = (60 + n) x 60

Area = 3600 + 60n

Hence, the area of the land is 3600 + 60n.

Answer:

x = 23.6°

Step-by-step explanation:

The given diagram shows a right triangle with an unknown angle, x.

We have been given the measures of the hypotenuse of the triangle and the measure of the side opposite unknown angle. Therefore, we can use the sine trigonometric ratio to find the value of x.

\(\boxed{\begin{minipage}{9 cm}\underline{Sine trigonometric ratio} \\\\$\sf \sin(\theta)=\dfrac{O}{H}$\\\\where:\\ \phantom{ww}$\bullet$ $\theta$ is the angle. \\ \phantom{ww}$\bullet$ $\sf O$ is the side opposite the angle. \\\phantom{ww}$\bullet$ $\sf H$ is the hypotenuse (the side opposite the right angle). \\\end{minipage}}\)

The unknown angle is x, so θ = x.

The side opposite the angle measures 6 units, so O = 6.

The hypotenuse of the triangle measures 15 units, so H = 15.

Substitute the values into the ratio and solve for x:

\(\sin x=\dfrac{6}{15}\)

     \(x=\sin^{-1}\left(\dfrac{6}{15}\right)\)

     \(x=23.5781784...\)

     \(x=23.6^{\circ}\; \sf (nearest\;tenth)\)

Therefore, the value of x is 23.6°.

The appropriate equation to solve for the missing angle is sin(x) = 6/15

From the question, we have the following parameters that can be used in our computation:

The right triangle

From the triangle, we have

Angle x

Also, we have the following sides in relation to x

Opposite = 6

Hypotenuse = 15

This means that we make use of the sine ratio

i.e. sin = opposite/hypotenuse

Using the above as a guide, we have the following:

sin(x) = 6/15

Hence, the equation is sin(x) = 6/15

Step-by-step explanation:

Number of 20-cent coins in the box are 33.

1. Let's assume the number of 20-cent coins to be x and the number of 50-cent coins to be y.

2. We can set up two equations based on the given information:

  - x + y = 54   (since the total number of coins in the box is 54)

  - 0.20x + 0.50y = 20.70   (since the total value of all the coins is $20.70)

3. We can multiply the second equation by 100 to get rid of the decimals:

  - 20x + 50y = 2070

4. Now, we can use the first equation to express y in terms of x:

  - y = 54 - x

5. Substitute the value of y in the second equation:

  - 20x + 50(54 - x) = 2070

6. Simplify and solve for x:

  - 20x + 2700 - 50x = 2070

  - -30x = -630

  - x = 21

7. Substituting the value of x back into the first equation:

  - 21 + y = 54

  - y = 33

8. Therefore, there are 21 20-cent coins and 33 50-cent coins in the box.
