Answer:

3 hours

Step-by-step explanation:

Recall:

Distance = speed x time

we are given that speed = 18 km/h and distance = 54 km.

hence,

54 = 18 x time   (divide both sides by 18 and rearrange)

time = 54/18 = 3 hours

Noah will take 3 hours to travel a distance of 54 kilometers at a constant speed of 18 km/h.

To determine how long Noah will take to travel a distance of 54 kilometers at a constant speed of 18 km/h, we can use the formula for time, which is:

Time = Distance / Speed

Let's calculate Noah's travel time:

Time = 54 km / 18 km/h = 3 hours

Noah will take 3 hours to cover the 54-kilometer distance on his bike.

Answer:

24.4

Step-by-step explanation:

diameter=2*radius

=2*12.2

=24.4

Final answer:

The diameter of a circle with a radius of 12.2 is 24.4 units. This is calculated by doubling the radius, using the formula D = 2r.

Explanation:

To determine the diameter of a circle with a radius of 12.2, you simply need to use the relationship between the radius and the diameter of a circle. The diameter is twice the radius, which can be represented by the formula D = 2r, where D is the diameter and r is the radius.

Substituting the value of the radius into the formula gives us:

D = 2 × 12.2

This calculates to:

D = 24.4

Therefore, the diameter of the circle is 24.4 units. Keep in mind that if the radius was given in a specific unit, like meters or centimeters, then the diameter will be in the same unit.

To find four decimals whose sum is 2.35, you can set up a system of equations and solve for the values. The four decimals are 0.10, 0.20, 0.15, and 0.15.

The question is asking for four decimals whose sum is 2.35. To find these decimals, we can assign variables to each decimal (let's call them a, b, c, and d) and set up an equation: a + b + c + d = 2.35. Since we want the decimals to have only two places after the decimal point, we can express them in hundredths. For example, instead of 0.1, we can write it as 10/100 = 0.10.

Now, we can set up a system of equations:

a + b + c + d = 2.35

a = 10/100

b = 20/100

c = 15/100

d = 15/100

By substituting the values back into the first equation, we have: (10/100) + (20/100) + (15/100) + (15/100) = 2.35. Simplifying the equation, we have 0.10 + 0.20 + 0.15 + 0.15 = 0.60. Therefore, the four decimals whose sum is 2.35 are 0.10, 0.20, 0.15, and 0.15.

Step-by-step explanation:

Add the whole numbers 4 + 3 = 7

Add the fractions 1/2 + 1/4

Rewrite 1/2 to have a common denominator with 1/4

1/2 = 2/4

Now add 2/4 + 1/4 = 3/4

The answer would be 7 3/4

Using the balance method, we find a = 15 by isolating the variable a. Substituting a = 15 back into the original equation, we verify the solution.

To solve the equation 12 = 2a - 18 using the balance method, we aim to isolate the variable a on one side of the equation.

Starting with 12 = 2a - 18, we'll first add 18 to both sides to isolate the term with 2a:

[tex]\[12 + 18 = 2a - 18 + 18\]\[30 = 2a\]\\[/tex]

Next, we divide both sides by 2 to solve for a:

[tex]\[\frac{30}{2} = \frac{2a}{2}\]\[15 = a\][/tex]

Now, let's verify the solution by substituting a = 15 back into the original equation:

[tex]\[12 = 2(15) - 18\]\[12 = 30 - 18\]\[12 = 12\][/tex]

Since the left side equals the right side, the solution a = 15 is verified.

Answer:

The function given by [tex]y = - (2)^{x} + 3[/tex] will have a range of y < 3.

Step-by-step explanation:

The function given by [tex]y = - (2)^{x} + 3[/tex] will have a range of y < 3.

This is because, for any real values of x, the term [tex]- (2)^{x}[/tex] will have a negative value. If we put x = 1, then, [tex]- (2)^{x}[/tex] = - 2, and for x = -1, then [tex]- (2)^{x}[/tex] = - 0.5.

That means [tex]- (2)^{x} < 0[/tex] for all real x.

Hence, [tex]- (2)^{x} + 3[/tex] < 0 + 3

⇒ y < 3 for all real x. (Answer)

10 ≤ x ≤ 30, x < 2y, x < 40.

Solution:

Given x is the number of graphing calculators produced daily and

y is the number of scientific calculators produced daily.

Step 1: A company produce atleast 10 and not more than 30 graphing calculators per day.

⇒ 10 ≤ x < 30

Step 2: Each day, the number of graphing calculators cannot exceed twice the number of scientific calculators produced.

⇒ x < 2y

Step 3: The number of scientific calculators cannot exceed 40 per day.

⇒ x < 40

Hence, the constraints are 10 ≤ x ≤ 30, x < 2y, x < 40.

Answer:

Step-by-step explanation:

The sum of the measures of the interior angles of an n-sided polygon is

(n - 2)180

A pentagon has 5 sides, so for a pentagon, n = 5.

(n - 2)180 = (5 - 2)180 = 3(180) = 540

The sum of the measures of the angles of a pentagon is 540.

You don't show the measures of the 4 angles that are known, so to answer the question, add the 4 given measures and subtract the sum from 540.

Answer:

The cost to rent each chair and each table are $1.5 and $8.75 respectively

Step-by-step explanation:

Let x represent 1 chair

Let y represent 1 table

Therefore

3x + 2y = 22   ------------(1)

5x + 6y = 60   ------------(2)

Multiply (1) by 5 and (2) by 3

15x + 10y = 110   ----------(3)

15x + 18y = 180  ------------(4)

Subtract (3) from (4)

8y = 70

Divide through by 8

y = $8.75

Substitute y = 8.75 in (1)

3x + 2y = 22

3x + 2(8.75) = 22

3x + 17.5 = 22

Collect like terms

3x = 22 - 17.5

3x = 4.5

Divide through by 3

x =$1.5

Final answer:

By setting up a system of linear equations based on the given information and solving it, we determined that the cost to rent each chair is $1.50 and the cost to rent each table is $8.75.

Explanation:

To find the cost to rent each chair and each table from the party rental company, we set up a system of linear equations based on the information given:

Let C be the cost of one chair and T be the cost of one table. We can write the following equations:

Solving this system of equations, we can find the values of C and T. First, multiply the first equation by 3 to eliminate T:

Now we can subtract the second equation from the modified first equation:

With the cost of a chair known, we can substitute back into either equation to find the cost of a table:

The cost to rent each chair is $1.50 and the cost to rent each table is $8.75.

Answer:

f(2)= -4

Step-by-step explanation:

f(x)= -x^3 + 6x - 7

f(2) = -2^3 + 6*2 - 7

f(2)= -8 +12 -7

f(2)= 3-7

f(2)= -4

The value of the function f(x)=-x^3+6x-7 at x=2 is -3.

To find the value of the function f(x) = -x^3 + 6x - 7 at x = 2, we substitute the value of x into the function.

So, f(2) = -(2)^3 + 6*(2) - 7 = -8 + 12 - 7 = -3.

Thus, the value of the function at x = 2 is -3. This is a simple algebraic operation involving cubes and multiplication, which are basic arithmetic operations.

The length of DZ is 4 units ⇒ 3rd answer

Step-by-step explanation:

Triangle X Y Z is cut by line segment C D, where

We need to find the length of DZ

In Δ XYZ

∵ C ∈ XY and D ∈ YZ

∵ CD // XZ

∴ m∠YCD = m∠YXZ ⇒ alternate angles

∴ m∠YDC = m∠YZX ⇒ alternate angles

In Δs YCD and YXZ

∵ m∠YCD = m∠YXZ

∵ m∠YDC = m∠YZX

∵ ∠Y is a common angle

∴ Δ YCD is similar to Δ YXZ by AAA postulate

- There is a constant ratio between their corresponding sides

∴ [tex]\frac{YC}{YX}=\frac{CD}{XZ}=\frac{YD}{YZ}[/tex]

∵ YC = 25 units

∵ CX = 5 units

∵ YX = YC + CX

∴ YX = 25 + 5 = 30 units

∵ YD = 20 units

∵ YZ = YD + DZ

∴ YZ = 20 + DZ

Let us use the ratio of the corresponding side

∵ [tex]\frac{YC}{YX}=\frac{YD}{YZ}[/tex]

∴ [tex]\frac{25}{30}=\frac{20}{20+DZ}[/tex]

- Simplify [tex]\frac{25}{30}[/tex] by dividing up and down by 5

∵ [tex]\frac{25}{30}=\frac{5}{6}[/tex]

∴ [tex]\frac{5}{6}=\frac{20}{20+DZ}[/tex]

- By using cross multiplication

∴ 5(20 + DZ) = 6(20)

∴ 100 + 5 DZ = 120

- Subtract 100 from both sides

∴ 5 DZ = 20

- Divide both sides by 5

∴ DZ = 4 units

The length of DZ is 4 units

Answer:

The Pie Eating Contest would be more skewed.

Step-by-step explanation:

In order to answer this, first we need to draw original histograms for both of these two events. Since all of the 20 people from the retirement community is attending one of the events, but we don't know which one, we need to draw new histograms for each of the events (see the attachment).

The only distinction of new histograms is the change in the fourth bin representing the 60-79 age group, since all visitors from retirement community fall into this age group.

A histogram is symmetrical if, when split in half by a vertical line, its left and right half act approximately as an object and its reflection in the mirror.

A histogram is skewed if, when split in half by a vertical line, one of its halves shows much greater values then the other.

So looking at our histograms, if all 20 people went to a Pie Eating Contest, that histogram would become more skewed and if all 20 people went to a Chili Cookoff, that histogram would become more symmetrical, which makes b) the correct answer.

Based on the information given, the correct option is B. The Pie Eating Contest would be more skewed.

This implies that when split in half by a vertical line, one of its halves will have greater values than the other.
