Riders for the Kiddie Koaster at the State Fair must be no more than 48 inches tall. Which inequality best expresses the height of the riders?

ANSWER:

64 square inches.

STEP-BY-STEP EXPLANATION:

The first thing is to calculate the ratio between the corresponding sides of the triangles:

We must bear in mind that the area of the larger t triangle is equal to the area of the small triangle multiplied by the ratio of the square, since the area is a quadratic unit, therefore:

The area of the larger triangle is 64 square inches.

By using the properties of operations, the result of the expression (10.3y)(4y) is [tex]41.2y^{2}[/tex]

The expression is given =  (10.3y)(4y)

The integers has mainly five properties of operation, closure property, associative property, commutative property, distributive property and the identity property. Each property has four integer operations. The four integer operations are addition operation, subtraction operation, multiplication operation and  division operation

The given expression = (10.3y)(4y)

Multiply the given expression using the properties of operation

(10.3y)(4y) = [tex]41.2y^{2}[/tex]

Hence, by using the properties of operations, the result of the expression (10.3y)(4y) is [tex]41.2y^{2}[/tex]

Consider that each unit on the grid represents 4ft. The figure consists of 2 identical equilateral triangles and 3 identical rectangles. Calculating the area of one of each kind of shape,

Therefore, the area of a single triangle is 8in^2, while the area of a rectangle is 48in^2. Calculate the total area as shown below

The area of a sheet of plywood is

Then, divide the total area by the area of a sheet of plywood,

Thus, the answer is 4.5, option D.

WE WILL FIRST FIND THE SLOPE BETWEEN THE POINTS

[tex]m = \frac{y2 - y1}{x2 - x1} \\ m = \frac{6 - 2}{2 - 4} \\ m = \frac{4}{ - 2} \\ m = - 2[/tex]

since the general equation of a straight line is given by y=mx+c

[tex]y = - 2x + 10[/tex]

ATTACHED IS THE SOLUTION

Answer:

Equation of line is given as y = mx + c, where m is the gradient and c is the y-intercept.

Find the gradient of the line first.

Formula of gradient is given as y2-y1 ÷ x2-x1 or y1-y2 ÷ x1-x2, where x and y are the coordinates of the points.

Gradient = (6-2) ÷ (2-4) = -2

Eqn is y = -2x + c

Substitute either one of the coordinates of the points into the equation to find c.

2 = -2(4) + c

c = 10

Equation of the line is y = -2x + 10

If a tire on the snowplow with a diameter of 3.2 ft turns 47 times then, the length of the street is 472.3 feet.

To clear a street the city workers use a snowplow. The diameter of the tire of the snowplow is 3.2 ft.

The tire has to turn 47 times to cover the total length of the street.

Now, we know that the circumference of a circle is given as:

C = 2πr where r is the radius of the circle. And the radius of a circle is half of its diameter.

Therefore, the circumference of the circle can be written as:

C = πD where D is the diameter of the circle.

Now, to calculate the total length of the street we will find the product of the circumference and the number of times the tire has to turn to cover the street.

Therefore,

Length of the street, L = nC

L = nπD

L = 47 × 3.14 × 3.2 ft

L = 472.256 ft

L = 472.3 ft

Hence, the length of the street is 472.3 feet.

Answer:

[tex]4*10^5[/tex]

Step-by-step explanation:

So whenever sometimes says "how many is x larger than y", it just means what is x divided by y. For example 4 is 2 times as much as 2 because 4/2 = 2

With this being said we can simply divide two numbers

[tex]\frac{2*10^{12}}{5*10^6}[/tex]

Whenever you divide scientific notation you simply divide the two coefficients and subtract the exponents from the base 10

So: [tex]\frac{2*10^{12}}{5*10^6} =\frac{2}{5} * 10^{12-6}[/tex]

This gives you a result of: [tex]0.4 * 10^6[/tex]

Since we want the coefficient to be: [tex]1\le c < 10[/tex] we can take one of the 10s from the base, since 10^6 is just 6 tens being multiplied by each other and we can "borrow" one of them to get: [tex]0.4*10^6=0.4*10*10^5[/tex] which simplifies to: [tex]4*10^5[/tex]

Based on the fact that the rectangular plot has a length that is 10 m longer than the width, the equation that will help to find area of the rectangular plot of land is 10x + x² = 10,000

To find the area of the plot of land is the same as finding the area of a rectangle which is:

Area of a rectangle = Length x Width

Assuming the width of the rectangular plot of ground is x, then the length would be:

= 10m + x

= 10 + x

The area of the rectangular plot of ground can therefore be found by the formula:

Area of a rectangle = Length x Width

10,000 square meters = (10 + x) × x

10,000 square meters = 10x + x²

10x + x² = 10,000

In conclusion, an equation that can help you to find the dimensions of the plot of ground is 10x + x² = 10,000.

The points at which the graph of f(x) has a horizontal tangent line are; x = -1, x = 0.4045, x = 2.07

The horizontal tangent of a function is simply defined as the point where the slope of the function is 0.

Now, we are give the function as;

f(x) = (2x² - 2x - 1)/(x⁴ + 1)

Slope of this function is;

f'(x) = -2(2x⁵ - 3x⁴ - 2x³ - 2x + 1)/(x⁴ + 1)²

Now, when the slope is zero, we will have that;

-2(2x⁵ - 3x⁴ - 2x³ - 2x + 1) = 0

Using an online polynomial root calculator, the roots of this slope are;

x = -1, x = 0.4045, x = 2.07

These values are the points where there is a horizontal tangent line.

a) The interest if computed using simple interest for 3 years at 2% is $120.

c) The interest when compounded continuously for 3 years at 2% is $123.67.

d) The difference in total interest between using simple interest and continuously compounding is $3.67.

Simple interest is a straightforward way of computing the interest paid on a loan.

The formula for calculating simple interest is P x R x T, where P = Principal, R = Rate, and T = Time.

The formula for continuous compounding first computes the future value (FV) from which the present value (PV) is deducted, as follows:

FV = PV x e ^ (i x t), where e is the mathematical constant approximated as 2.7183.

Principal = $2,000

Rate of interest = 2%

Period = 3 years

Simple Interest = $120 ($2,000 x 2% x 3)

Continuous compounding = FV - PV

FV = $2,000 x 2.7183 ^ (0.02 x 3)

= $2,000 x 1.06183697

= $2,123.67

Interest = $123.67 ($2,123.67 - $2,000)

The difference in total interest = $3.67 ($123.67 - $120)

Thus, continuous compounding produces a difference in the interest of $3.67 when compared to simple interest.

Answer: The angles in an equilateral triangle are always 60°. When a triangle has two congruent sides it is called an isosceles triangle. The angles opposite to the two sides of the same length are congruent. A triangle without any congruent sides or angles is called a scalene triangle.

Step-by-step explanation:

The simplest way to prove that triangles are congruent is to prove that all three sides of the triangle are congruent. When all the sides of two triangles are congruent, the angles of those triangles must also be congruent. This method is called side-side-side, or SSS for short.
