Given the graph of y=f(x) below, solve f(x)=3 for x

Answer: Because there is no image or question I have to make a question myself. If Jimmy had X and Samantha has 17 which is 8 more than Tim and Tim has 20 less than Jimmy. What does Jimmy have?

Step-by-step explanation:

First, we isolate X.

X = Tim + 20.

Tim = 11.

11 + 20 = X

So X = 31

Answer: The mass of one mole of a substance is equal to its molar mass in grams. The molar mass of a substance is the mass of one mole of that substance and is usually expressed in atomic mass units (amu) or grams per mole (g/mol).

One mole of a substance contains Avogadro's number of particles, which is approximately 6.022 x 10^23.

Since the mass of one doughnut is given in grams (74 g), we can assume that this is the molar mass of the substance in question. So, the mass in grams of one mole of the substance is:

Mass of one mole = 74 g

So, the answer to two significant figures is:

Mass of one mole = 74 g (rounded to two significant figures).

105 watts

The middle wattage is found by taking the average of the highest and lowest wattages. To find the average, you add the two numbers together and then divide by 2. In this case, the lowest wattage is 60 and the highest is 150, so when we add these two numbers together, we get 210. Then, when we divide 210 by 2, we get 105. So the middle wattage is 105 watts.

Cross sections parallel to any face will have the same shape as the face. Those may or may not be square, depending on the shape of the face.

However, if a cross section may be made at any angle, there is always a cross section of a rectangular prism that can be a square. The attached figure shows an example.

The required area of the shaded region is 11.5 sq. units

Area is defined as the total space taken up by a flat (2-D) surface or shape of an object.

Given is a circle with center T and radius 3 units. there is a region in the circle which is shaded, we need to find that area.

So, the shaded part is composed of a right triangle and a minor sector of the circle.

To find the area of the shaded portion, we will add the area of right triangle and a minor sector

Now, area of a triangle = 1/2 × base × height

Here, base = height = radius = 3 units

And,

Area of a sector = θ/360° × π × radius²

Where, θ is the central angle.

θ = 90°

Area of the shaded region = 1/2 × 3 × 3 + 90°/360° × 3.14 × 3²

= 9/2 + 7.065

= 11.565

Hence, the required area of the shaded region is 11.5 sq. units

The boat speed in still water is 2 km/hr.

Speed is a measure of how fast an object is moving. It is defined as the distance traveled by an object in a given amount of time. Speed is a scalar quantity, meaning it only has magnitude and does not have direction. It is typically expressed in units of distance per time, such as meters per second (m/s) or miles per hour (mph). The formula for speed is speed = distance / time. It is important to distinguish speed from velocity, which is a vector quantity that includes both magnitude (speed) and direction.

The formula to calculate the speed of the boat in still water is:

speed = distance / (time up + time down)

To use this formula, we first need to find the distance traveled upstream and downstream. Let's assume that the distance traveled upstream and downstream is the same, so we can use the average of the two times: (30 min + 10 min) / 2 = 20 min.

Next, we need to convert the time to hours. 20 minutes is equal to 20/60 = 1/3 hours.

Now, let's calculate the distance using the current speed of 2 km/hr:

distance = current speed * time

distance = 2 km/hr * 1/3 hours = 2/3 km

Finally, we can use the formula to calculate the boat speed:

speed = distance / time = 2/3 km / (1/3 hours) = 2 km/hr

The total surface area painted black is 50.2 square feet.

Let's call the radius of the base of the cone r. We can find it using the formula for the circumference of a circle:

C = 2πr

8π = 2πr

r = 4

Next, let's find the slant height of the cone, which is the distance from the tip of the cone to the base along a straight line that passes through the center of the base. We can use the Pythagorean theorem:

s^2 = r^2 + h^2

s^2 = 4^2 + 12^2

s^2 = 16 + 144

s^2 = 160

s = sqrt(160) = 12.8

Next, let's find the surface area of one cone. The surface area of a cone is equal to π times the radius of the base times the slant height, plus π times the radius of the base squared:

A = πr * s + πr^2

A = π * 4 * 12.8 + π * 4^2

A = 50.24 + 16π

A = 50.24 + 50.24

A = 100.48

Since the base and 50% of the lateral surface of each cone is painted red, that means 50% of the surface area is painted black:

black_area = 0.5 * 100.48

black_area = 50.24

Rounding to the nearest tenth, the total surface area painted black is 50.2 square feet.

Answer step bby step:

1/5(4x - 2.5) = 5(0.4x + 10) + 3 1/2

5(0.4x + 10) + 3 1/2 = 1/5(4x - 2.5)

2. Multiply both sides by 5:

2(0.4x + 10) + 3 1/2 = 4x - 2.5

3. Subtract 2(0.4x + 10) from both sides:

3 1/2 = 4x - 2(0.4x + 10)

4. Subtract 3 1/2 from both sides:

0 = 4x - 2(0.4x + 10) - 3 1/2

5. Distribute the -2 to the parentheses:

0 = 4x - 0.8x - 20 - 3 1/2
