Which fraction is closest to 1/2

Answer:

Step-by-step explanation:

h(-6) is the same as saying when t=-6

so for this question, every time you see t you plug in -6 instead

so h(t)=6t-6

h(-6)=6(-6)-6

=-36-6=-42

Therefore, h(-6)=-42

A) The volume of the container is 60 cubic ft.

B) The cost of the sand is $75.

What is the volume of the trapezoidal prism?

To find the volume of a right trapezoidal prism, we can use the formula:

V = (bh)/2 * l

where b is the length of the shorter base, h is the height, and l is the length of the longer base.

Given that b = 3ft, h = 8ft and l = 5ft, we can substitute the values into the formula:

V = (38)/2 * 5 = 125 = 60 cubic ft

So the volume of the container is 60 cubic ft.

B. To find the cost of the sand, we can use the formula:

Cost = Volume of container * cost per cubic foot

Given that the cost per cubic ft is $1.25 and the volume of the container is 60 cubic ft, the cost of the sand is :

Cost = 60 * 1.25 = $75

The cost of the sand is $75.

Hence,

A) The volume of the container is 60 cubic ft.

B) The cost of the sand is $75.

If a child's toy is in the shape of a square pyramid. The pyramid stands 18 inches tall and each side of the base measures 24 inches. the surface area of the toy that is yellow is  432 square inches.

The surface area of the square pyramid can be calculated as follows:

Base area = side length * side length

Base area = 24 inches * 24 inches

Base area = 576 square inches

Slant height = √ (side length * side length + height * height)

= √(24 * 24 + 18 * 18)

= 30 inches

Lateral area = 4 * base area / slant height

Lateral area = 4 * 576 / 30

Lateral area= 288 square inches

Total surface area = lateral area + base area

Total surface area = 288 square inches + 576 square inches

Total surface area = 864 square inches

The yellow surface area = total surface area / 2

The yellow surface area = 864 square inches / 2

The yellow surface area = 432 square inches

Therefore the yellow surface area is  432 square inches.

Step-by-step explanation:

This is an inequality in the standard form of "ax + b > c" where a, b, and c are constants. In this case, a = 1.70, b = 41.70, and c = 153.90.

To solve this inequality, we need to get x alone on one side of the inequality. We can do this by subtracting 41.70 from both sides, which gives us:

1.70x > 112.20

Then we can divide both sides by 1.70, to get:

x > 66.12

So the solution set to this inequality is all the values of x that are greater than 66.12. This can be written as x > 66.12.

It's important to note that this inequality means that x can be any number greater than 66.12 (66.12 is not included in the solution set)

Each book weighs 1.6 pounds, if a stack of 6 books weighs 9.6 pounds and all books weight is equal.

The force exerted on an object by gravity is referred to as the weight of an object in science and engineering.

Some common textbooks define weight as a vector quantity, or the gravitational force acting on the object. Others refer to weight as a scalar quantity, or the strength of the gravitational pull. Others define it as the strength of the force applied to a body by mechanisms that counteract the effects of gravity: the weight is the unit of measurement.

So, the weight would be 0 when in free fall. Terrestrial objects are capable of having no weight in this sense. For example, by ignoring air resistance, the famous apple that fell from the tree and collided with the ground near Isaac Newton would have no weight.

If all book weighs equally then each book weighs

9.6/6

= 1.6 pounds

The distance formula is a mathematical equation used to calculate the distance between two points.

Distance is the measure of length between two points. It is the length of the path between the two points, usually measured in meters, kilometers, miles, or the like. Distance can be measured in time, such as in walking or running, or in terms of space, such as in astronomy or geography. Distance is often used to measure the difference between two places, objects, or people. Distance can also be used to measure changes in position, direction, and speed.

It is a simple equation that takes the coordinates of two points and finds the straight line distance between them. To find the distance between two points on a graph, simply use the distance formula.

Let's say that the two points are (x1, y1) and (x2, y2). The distance formula is:

Distance = √[(x2 - x1)2 + (y2 - y1)2]

For example, let's say point one is (3, 4) and point two is (6, 8). Using the distance formula, we can find the distance between the two points by plugging in the values:

Distance = √[(6 - 3)2 + (8 - 4)2]

Distance = √[32 + 42]

Distance = √[25 + 16]

Distance = √41

Distance = 6.4

So the distance between the two points is 6.4 units. This is the length of the line segment that connects the two points.

Since a triangle has three sides and three vertices, it is a polygon. It is a fundamental geometric shape. Triangle ABC is the moniker given to a triangle that has vertices A, B, and C. When the three points are not collinear, a singular plane and triangle are found in Euclidean geometry. A triangle is a polygon if it has three sides and three corners. The points where the three sides meet are known as the triangle's corners. The product of three triangle angles is 180 degrees.

A function, in mathematics, an expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable).

The domain of a function f(x) is the set of all values for which the function is defined, and the range of the function is the set of all values that function takes.

Given are two functions as given in question.

[ 1 ] -

We can write the net change in the value as -

Δf(t) = {f(2 + h) - f(2)}

Δf(t) = {5(2 + h)² - 5(2)²}

Δf(t) = 5(4 + h² + 4h) - 5(4)

Δf(t) = 5{h² + 4h}

[ 2 ] -

f(t) = 5t²

t = (2)   to   t = (2 + h)

Now, for the given intervals, we can write the average rate of change

as -

{r} = Δf(t)/Δt

{r} = {f(2 + h) - f(2)}/{2 + h - 2}

{r} = {5(2 + h)² - 5(2)²}/{h}

{r} = {5(4 + h² + 4h) - 5(4)}/{h}

{r} = 5{(4 + h² + 4h) - 4}/{h}
