Ms. Sculley needs to arrange 28 chairs into equal rows. She needs more than 2 chairs in each row and more than 2 rows. How many rows will she have?​

Answer:

Louis can seal the driveway in 5.41 hours.

Step-by-step explanation:

[tex]\frac{1}{4}[/tex] + [tex]\frac{1}{x}[/tex] = [tex]\frac{1}{2.3}[/tex]                  4 × 1x × 2.3 = 9.2x

9.2x([tex]\frac{1}{4}[/tex] + [tex]\frac{1}{x}[/tex] = [tex]\frac{1}{2.3}[/tex])

2.3x + 9.2 = 4x

9.2 = 1.7x

x= 5.411764706

Answer: A dilation is a transformation that produces an image that is the same shape as the original one,but in in different size. A dilation of a figure can make the figure bigger or smaller in the coordinate plane.

Step-by-step explanation:

Answer:

A dilation is a type of transformation in which an image is enlarged or shrunk. This does not change the shape other than the fact that it is bigger or smaller.

Step-by-step explanation:

Think of it this way: When Ant Man grows or shrinks, his hair doesn't change color or he isn't missing an arm or anything. Nothing about his body shape is changed- He is just smaller or bigger. That's essentially how a dilation works. Hope this helped!

The surface area of the yellow surfaces on the wheel pod is 20 square inches

The yellow surfaces on the wheel create a circle with the following parameter:

Diameter, d = 5 inches

The radius (r) is calculated using:

r = d/2

So, we have:

r = 5/2

Evaluate

r = 2.5

The surface area is then calculated using:

A = πr²

So, we have:

A = 3.14 * 2.5²

Evaluate

A = 19.625

Approximate

A = 20

Hence, the surface area of the yellow surfaces on the wheel pod is 20 square inches

Answer:

A) 6 < c < 18

Step-by-step explanation:

A triangle is known to have 3 sides: Side a, Side b and Side c.

For a triangle, one of the three sides is longer than the other two sides. (The only exception is when we are told specifically that a triangle is an equilateral triangle, where all the 3 sides are equal to each other).

To solve the above question, we would be using the Triangle Inequality Theorem.

The Triangle Inequality Theorem states that the summation or addition of the lengths of any two sides of a triangle is greater than the length of the third side.

Side a + Side b > Side c

Side a + Side c > Side b

Side b + Side c > Side a

For the above question, we have 2 possible side lengths for the third side of the triangle. We are given in the above question,

side (a) = 6

side (b) = 12

Let's represent the third side as c

To solve for the above question,we would be having the following Inequality.

= b - a < c < b + a

= 12 - 6 < c < 12 + 6

= 6 < c < 18

Therefore, the possible side lengths for the triangle is the above question is Option A) 6 < c < 18

Answer:

y = 4.8

Step-by-step explanation:

I set up a proportion to solve this. I divided 9.6 by 8 to find the ratio. Then, with the ratio as 1.2, I multiplied 1.2 and 4 together to get 4.8, which is y.

Answer:

y= 2x -8

Step-by-step explanation:

To find  the equation of a line passing through (5,2) and parallel to the line represented by the equation y= 2x + 1, we will follow the steps below;

since the line is parallel to y=2x + 1, then the will have the same slope. That is; m₁ = m₂

comparing  y = 2x + 1 to y = mx + c

m= 2

we will substitute m= 2 x= 5  and y = 2  into y = mx + c and then solve for c

y = mx + c

2 = 2(5) + c

2 = 10 + c

subtract 10 from both-side of the equation

2-10 = 10 -10 + c

-8 = c

c=-8

To find our equation, we will substitute m = 2  and c=-8 into y=mx + c

y = 2x - 8

Therefore, the equation of a line passing through (5,2) and parallel to the line represented by the equation y= 2x + 1      is    y= 2x -8

Answer:

48 in

Step-by-step explanation:

The diagonal of the inscribed square equals the diameter of the circle.

1. Calculate the diagonal of the square

d = 2r = 2 × 6√2 in =12√2 in

2. Calculate the side of the square

∆ACB is an isosceles right triangle.

We can use Pythagoras' Theorem to calculate the length of a side s.

[tex]\begin{array}{rcl}s^{2} + s^{2} & = & (12\sqrt{2})^{2}\\2s^{2} & = & 144 \times 2\\s^{2} & = & 144\\s & = & \text{12 in}\\\end{array}[/tex]

3. Calculate the perimeter of the square

P = 4s = 4 × 12 in = 48 in

The perimeter of the square is 48 in.

The perimeter of the square in inches is 48 square inches

The diameter of the circle is twice the given radius

Given the following:

radius = 6√2

diameter = 2(6√2)

diameter = 12√2

The diagonal of the cube inscribed will be equal to the diameter of the circle.

Next is to get the side length "l" of the square using the Pythagoras theorem. According to the theorem:

l²+l² = (12√2)²

2l² = 144(2)

l² = 288/2

Take the square root of both sides

l² = 144

l = √144

l = 12inches

Next is to get the perimeter of the square

Perimeter of the square = 4L

Perimeter of the square = 4(12)

Hence the perimeter of the square is 48 square inches

Answer:

Step-by-step explanation:

Surface area is the sum of the areas of all faces (or surfaces) on a 3D shape. A cuboid has 6 rectangular faces. To find the surface area of a cuboid, add the areas of all 6 faces. We can also label the length (l), width (w), and height (h) of the prism and use the formula, SA=2lw+2lh+2hw, to find the surface area.

Answer:

Step-by-step explanation:

Elevators are a safer way that using a ladder, or any other option, because it has really good foundations, so you won't fall, and it has a floor which you can stand on safely.

Stairs are also safer than ladders, because you can have more estability on the surface, preventing any falls.

At last, ramps are also safer than ladders, but less safe than elevators or stairs, because they have an inclined surface, so you can slide.

Now, if we analyse these four options, we can say that their difference is about the frictional surface each of them have, and the null slope some of them have. For example, a ladder is dangerous, because you don't enough surface to step on, also, the friction of its surface is lower, that means you can easily fall. But, elevators, stairs and ramps have greater coefficient of friction on their surface, and also, they have a greater surface area.

like you see, there are 2 line on the triangle.

68° is looking in front of one line, so the other line's front have to be 68°

now we found 2 corner of triangle.

a triangle's sum of interior angles equal to 180°

68°+68° = 136°.

now i have to remove 136 from 180 to find our x

180°-136° = 44°

x = 44°

Please see attached formula

The monthly payments to pay off the loan is $1528.3

A loan is a form of debt incurred by an individual or other entity. The lender—usually a corporation, financial institution, or government.

Given that, you took a loan, of $15,000, $2,250 down and finance the rest to pay off the loan in 5 years at 12% true annual interest.

Interest will be on = 15000 - 2250 = 12750

Formula to be used :-

PV = PMT / i [1-1/(1+i)ⁿ]

12750 = PMT / 0.12[1-/(1+0.12)⁶⁰]

12750 = PMT / 0.1198

PMT = 1528.29622

Hence, the monthly payments to pay off the loan is $1528.3

30.87%

Step-by-step explanation:

Priya's simulation is fine, as 30% is represented by the 3 white cubes.

The more times the experiment is carried out, the closer it is to the theoretical probability, which is calculated as follows:

p (n = x) = nCx * p ^ x * q ^ (n-x)

We obtain that p = 0.3 and q = 1-0.3 = 0.7. also n = 5 and x = 2.

replacing we have:

p (5 = 2) = 5C2 * 0.3 ^ 2 * 0.7 ^ (5-2)

p (5 = 2) = 5! / (2! * 3!) * 0.03087

p (5 = 2) = 0.3087

which means that the probability is 30.87%, and the more the experiment is carried out, the closer it is to this probability.
