Luke has 22 lots for sale. Each lot is 1.63 acres. How much land does Luke have for sale?
OA 37.49 acres
OB. 36.76 acres
OC. 35.86 acres
OD 38.06 acres
Answer: 35.86acres
Step-by-step explanation:
Luke has 22lots for sale
Each lot is 1.63acres
Since each lot is 1.63acres and there are 22lots
So Luke has
22×1.63acres
=35.86acres
Final answer:
Luke has 35.86 acres of land for sale, which is the product of multiplying 22 lots by 1.63 acres per lot.
Explanation:
To calculate the total amount of land Luke has for sale, multiply the number of lots by the acreage of each lot. There are 22 lots for sale, and each lot measures 1.63 acres. The calculation is as follows:
Total land = Number of lots * Acreage of each lot
Total land = 22 * 1.63
Total land = 35.86 acres
So, Luke has a total of 35.86 acres of land for sale, which corresponds to option OC.
The length of a rectangle is 1 m more than twice the width, and the area of the rectangle is 45 m . Find the dimensions of the rectangle.
The length and width of the rectangle is 10 m and 4.5 m respectively.
Step-by-step explanation:
Given,
The length of a rectangle is 1 m more than twice the width.
Area of the rectangle = 45 sq m
To find the length and width of the rectangle.
Formula
If the length and width of a rectangle be l and b respectively, the area will be lb.
Let, the width (b) be = x and
Length (l) = 2x+1
According to the problem,
(2x+1)x = 45
or, [tex]2x^{2} +x = 45[/tex]
or, [tex]2x^{2}+x-45 = 0[/tex]
or, [tex]2x^{2}+(10-9)x-45 = 0[/tex]
or, [tex]2x^{2}+10x-9x-45 = 0[/tex]
or, 2x(x+5)-9(x+5) = 0
or, (2x-9)(x+5) =
Hence,
2x-9 = 0 and x+5 = 0
or, x = [tex]\frac{9}{2}[/tex] and x= -5
We will take x = [tex]\frac{9}{2}[/tex] as the value of length cannot be negative.
So,
Width = 4.5 m and Length = 2×4.5+1 = 10 m
The area of a rectangle is determined by the product of its length and width. In this rectangle, the width (W) is found to be 5 meters by solving the given equation. The length, being 1 meter more than twice the width, is 11 meters.
Explanation:To solve this problem, you can use the formula for the area of a rectangle, which is Area = length × width. You know from the problem that the area of the rectangle is 45 square meters, and the length (L) is 1 meter more than twice the width (W).
You can thus express the length in terms of the width: L = 2W + 1. Substituting this into the formula for the area gives you: 45 = W × (2W + 1).
Solving this equation involves expanding the right side: 45 = 2W² + W, arranging the equation to set the right side to zero: 2W² + W - 45 = 0
By factoring or using the quadratic equation, you find that the roots of the equation (the possible values for W) are 5 and -4.5. Since a negative width doesn't make sense in this context, you discard -4.5, and your width is thus 5 meters.
The length is then 2W + 1 = 2(5) + 1 = 11 meters. So, the dimensions of the rectangle are 5 meters by 11 meters.

What is the radius of a hemisphere with a volume of 60,750π cm3?
The radius of the hemisphere is 45 cm
Explanation:
Given:
Volume of the hemisphere, V = 60750π cm³
Radius of the hemisphere, r = ?
We know:
Volume of hemisphere = [tex]\frac{2\pi r^3 }{3}[/tex]
[tex]60750\pi = \frac{2\pi r^3 }{3} \\\\r^3 = 91125\\\\r = 45[/tex]
Therefore, the radius of the hemisphere is 45 cm
The radius of the hemisphere is 45 cm
The volume of a hemisphere is given by the formula
[tex]V = \frac{2}{3} \pi r^{3}[/tex]
Where V is the volume
and r is the radius
From the question,
V = 60750π cm³
Putting this into the formula,
We get
[tex]60750\pi = \frac{2}{3}\pi r^{3}[/tex]
∴ [tex]r^{3}= \frac{60750\pi \times 3}{2\pi}[/tex]
[tex]r^{3}= 91125[/tex]
∴ [tex]r =\sqrt[3]{91125}[/tex]
r = 45 cm
Hence, the radius of the hemisphere is 45 cm

Celine flipped a coin 100 times. She flipped heads 41 times and tails 59 times. What is the experimental probability that the next flip will be heads?
A - 41/100
B - 1/2
C - 3/4
D - 59/100
Answer:
B - 1/2
Step-by-step explanation:
In this situation each experiment does not affect the probability of the next one. That is, each experiment is independent of the rest. Hence, independently of the result of the first 100 times the next probability in which Celine does the experiment, the propability will be 1/2.
B - 1/2
Answer:
B- 41/100
Step-by-step explanation:
Because this is an experimental (not theoretical) probability, which is the ratio of number of outcome as head over the total number of trial, the experimental probability of the next flipping be head would be the total number of heads that she'd gotten before over the total number of times that she'd try, which is 41 / 100

The external angles of a 12-gon add up to 360 degrees so each is 30 degrees. That makes the internal angle the supplement, PQR=150 degrees.
We have an isosceles triangle so the other two angles add to 30 degrees, so 15 degrees.
Answer: 15 degrees
Angle PRO in a regular 12-gon is half an interior angle, so it measures [tex]$\boxed{75^\circ}$[/tex].
The strategy is to first calculate the sum of the interior angles of the dodecagon, and then divide that number by 2 because any angle of a regular polygon can be found by subtracting [tex]$180^\circ$[/tex] from the quotient you get when you divide the sum of the interior angles by the number of angles.
Here's the solution:
The sum of the interior angles of a polygon is given by the formula [tex]$(n-2)\times180^\circ$[/tex], where n is the number of sides.In a dodecagon, there are n=12 sides.Therefore, the sum of the interior angles of the dodecagon is [tex]$(12-2)\times180^\circ = 1800^\circ$[/tex].Since each angle of a regular polygon is equal, all the interior angles of the dodecagon measure [tex]$\frac{1800^\circ}{12} = 150^\circ$[/tex]Since [tex]$\angle PRO$[/tex] is half of an interior angle of the dodecagon, it measures [tex]$\frac{1}{2}\times150^\circ = \boxed{75^\circ}$[/tex].Asher built two bookends and wants to paint them. How much paint will he need to cover the surface of both bookends? 468 cm2 576 cm2 936 cm2 1,044 cm2
Asher will need c. 936 cm² of paint to cover both the bookends.
Step-by-step explanation:
Step 1:
To determine the amount of paint needed, we determine the surface area of the triangular prisms.
To calculate the triangular prism's surface area, we calculate the areas of all the 5 sides. We divide the prism into 2 triangles and 3 rectangles, find the areas individually and then sum them all up in order to determine the area of the entire triangular prism.
Step 2:
There are two triangles with base lengths of 9 cm and heights of 12 cm. A triangle's area is half the product of the base length and its height.
Area of 1 triangle = [tex]\frac{1}{2} (9)(12) = 54[/tex] cm².
Area of both triangles = 2× Area of 1 triangle [tex]= 2(54)[/tex] = 108 cm².
Step 3:
There are three rectangles with a common length of 10 cm but there are three different widths. Any rectangle's area is calculated by multiplying the rectangle's length with its width.
Area of a rectangle with width 15 cm [tex]= (10)(15) = 150[/tex] cm².
Area of a rectangle with width 9 cm [tex]= (10)(9) = 90[/tex] cm².
Area of a rectangle with width 12 cm [tex]= (10)(12) = 120[/tex] cm².
Step 4:
The area of the entire triangular prism = Area of 2 triangles + Area of all the 3 rectangles = [tex]108+150+90+120 = 468[/tex] cm².
This is the surface area of 1 bookend. As both the bookends are similar.
The surface area of 2 bookends [tex]= 2(468) = 936[/tex] cm².
Asher will need 936 cm² of paint to cover both the bookends.

Kimani ordered party hats for his son's birthday party and
spent over $40. If he ordered the hats from Party Plus, write
an inequality to represent the possible number of hats he
ordered.
The inequality representing the possible number of party hats (x) Kimani ordered from Party Plus is x>20. This means Kimani ordered more than 20 party hats to spend over $40, given the assumed minimum cost per hat from Party Plus.
Let's denote the number of party hats Kimani ordered from Party Plus as x. Now, if each party hat costs a certain amount, and Kimani spent over $40, we can set up an inequality to represent this situation.
Let be the cost of each party hat. The total cost (T) is given by multiplying the number of hats (x) by the cost per hat (c). Therefore, T=xc.
The problem states that Kimani spent over $40, so we can express this as an inequality: T>40
Now, substitute the expression for T in terms of x and xc>40
Since we are specifically looking at the scenario where Kimani ordered the hats from Party Plus, let's assume that each hat costs at least $2 (as a hypothetical example). So, c≥2. Now, substitute
c≥2 into the inequality:
x⋅2>40
Simplify the inequality:
2x>40
Now, divide both sides by 2 to solve for x>20.
Find the value of c that makes the expression a perfect square trinomial.

A) 225/4
B) 225/2
C) 30
D) 225
The value of c that makes the expression x² − 15x + c a perfect square trinomial is obtained by squaring half the coefficient of x, which in this case is 225/4. Therefore option A is the correct answer.
To find the value of c that makes the expression x² − 15x + c a perfect square trinomial, we need to find a value for c such that the trinomial can be expressed as the square of a binomial.
This binomial will have the form (x - h)², where h is half the coefficient of the x term in the original trinomial.
In this case, the coefficient of x is -15.
Half of -15 is -15/2.
Squaring this value will give us c. Thus, (-15/2)² equals 225/4.
The value of c that makes the expression a perfect square trinomial is 225/4.
