Answer:

15.833 pints of chalkboard paint

Step-by-step explanation:

Surface area of a rectangular prism = 2(lw × hl × hw)

Where,

L = length = 15 feet

w = Width = 13 feet

h = height = 10 feet

Surface area of a rectangular prism = 2(lw + hl + hw)

= 2(15*13 + 10*15 + 10*13)

= 2(195 + 150 + 130)

= 2(475)

= 950 square feet

One pint of chalkboard paint covers 60 square feet

Least number of pints needed to paint the walls = 950 square feet / 60 square feet

= 15.833 pints of chalkboard paint

Answer:

0.2, 0.8

Step-by-step explanation:

The area of the park is 0.5h(b1 + b2), where h is the height, b1 is the first base, and b2 is the other base.

Plug the values in:

Area = 0.5(50)(50+90) = 0.5(50)(140) = (50)(70) = 3500

Since 700 people are in the park, there is 700/3500 = 0.2 people per square yard.

If the bases and height are halved, the new area is:

Area = 0.5(25)(25+45) = (35)(25) = 875

The new population density is 700/875 = 0.8 people per square yard.

The value of x for which the trinomial 2x^2−x+55 equal to the square of binomial x+5 is 5 and 6

Given the equation 2x^2−x+55, if the expression is equal to the square of binomial x + 5, then;

2x^2−x+55 = (x+5)^2

2x^2−x+55 = x^2 + 10x + 25

Collect the like terms;

2x^2-x^2-x-10x+55-25 = 0

x^2 - 11x + 30 = 0

Factorize the result

x^2 - 6x - 5x + 30 =0

x(x-6)-5(x-6) = 0

x-5 = 0 and x - 6  = 0

x = 5 and 6

Hence the value of x for which the trinomial 2x^2−x+55 equal to the square of binomial x+5 is 5 and 6

Step-by-step explanation:

The area of the triangle, Δ AMN is 8 cm², so the area of the triangle, ΔMCN is 24 cm².

A triangle is one of the most basic geometric figures with 3 sides, 3 angles, and 3 vertices.

The area of a triangle is half of the product of the base and height.

Given that

ABCD is square and M and N are mid-points of lines AB and AD respectively.

Area of triangle, ΔAMN = 8 cm²

[tex]\dfrac{1}{2} \times AN \times AM = 8\\AN \times AM = 8 \times 2\\AN \times AM = 16[/tex] ...(i)

Since ABCD is square, therefore AB = AD.

Also, as M and N are mid-points of lines AB and AD, so

AN = AM.

Substitute AN = AM in equation (i),

[tex]AN \times AN = 16\\AN^2 = 16\\AN = \sqrt{16}\\AN = 4\ cm[/tex]

So,

AD = 2 × AN

     = 2 × 4

     = 8 cm

As ABCD is square,

AB = BC = CD = AD = 8 cm.

Area of the square ABCD = 8² = 64.

Since CD = BC, ND = MB, ∠D = ∠B.

Therefore by SAS property of similarity,

ΔCDN ≅ ΔCBM

Area of the triangle, ΔCDN = Area of the triangle, ΔCBM.

                                              [tex]= \dfrac{1}{2} \times CB \times BM\\= \dfrac{1}{2} \times 8 \times 4\\\\= 16\ cm^2[/tex]

Area of the triangle, ΔCMN = Area of ABCD - Area of ΔAMN - Area of ΔCDN - Area of ΔCBM

Area of the triangle, ΔCMN = 64 - 8 - 16 - 16

                                              = 24 cm²

Therefore, the area of ΔCMN  is 24 cm².

Answer:

The equation that represents the relationship between 'y' the total points, and 'x' the number of movies is option A;

A y = 3·x

Step-by-step explanation:

The information required in the question is an equation that represents the the relationship between the number of movie attended and the total number of points Marcy has given that she earns a fixed amount of points for attending each movie

The number of points she will earn for attending each movie = 3 points

The total number of points she will earn 'y' when she attends 'x' number of movies is given as follows;

y = 3 + 3 + 3 + ... + 3, 'x' number of times, and we can write

[tex]y = \sum\limits_{i =1}^x 3 = 3 \times x[/tex]

Therefore the equation that represents the relationship between 'y' the total points, and 'x' the number of movies is y = 3·x.

Answer:

Yes. They are similar because they have the same shape and one is just flipped and smaller.

Answer: Yes

Step-by-step explanation: For a quadrilateral to be similar, the angles must be congruent. This is true since the angle measures are the same since it flipped and dilated.

Answer:

12) z = 64

15) q = 75

Step-by-step explanation:

12) 40/65 = z/10⁴

Cross Multiply

65 × z = 40 × 104

65z = 4160

z = 4160 / 65

z = 64

15)32.5/25 = 97.5/q

Cross Multiply

25 × 97.5 = 32.5× q

q = 25 × 97.5/32.5

q = 2437.5 /32.5

q = 75

Answer:

124.3 ft

Step-by-step explanation:

We solve the above question using the Trigonometric function of Tangent

= tan θ = Opposite/Adjacent

θ = Angle of Elevation = 73°

Adjacent = 38 ft

Opposite = x

Hence

tan 73° = x/38 ft

Cross Multiply

x = tan 73° × 38 ft

x = 124.2923995 ft

Approximately = 124.3 ft

Therefore, Nick is 124.3 ft from the ground.

What are your answer choices?

Answer:

Median --> 357.5

Q1 --> 298

Q3 --> 422

IQR > 124

Step-by-step explanation:

3 daily attendance at the water park: 346, 250, 433, 369, 422,298

Find the median, Q1, Q3,and IQR

Step 1

We rearrange the given data set

250, 298, 346, 369, 422, 433

a) The Median

The formula to find the Median

= 1/2( n + 1)th term

Where n = Number of terms = 6

Median = 1/2(6 + 1)th

= 1/2(7)th term

= 3.5th term

The 3.5th term = The number between the 3rd and 4th term

3rd term = 346

4th term = 369

Hence,Median = 346 + 369/2

= 357.5

2) Q1 = First Quartile

= 1/4(n + 1)the

= 1/4( n + 1)th term

Where n = Number of terms = 6

Median = 1/4(6 + 1)th

= 1/4(7)th term

= 1.75th term

The 1.75th term = 2nd term

= 298

Q1 = 298

3) 3/4( n + 1)th term

Where n = Number of terms = 6

Median = 3/4(6 + 1)th

= 3/4(7)th term = 21/4th term

= 5.25th term

The 5.25th term = 6th term

Q3 = 422

4) Interquartile Range = Q3 - Q1

= 422 - 398

= 124

Answer:

No, she should have added ([tex]6^2[/tex]) and ([tex]8^2[/tex]) and compared that too ([tex]10^2[/tex]).

Step-by-step explanation:

An easy way to determine if a triangle is right is by using the Pythagorean theorem. The Pythagorean theorem states the following,

[tex]a^2 + b^2 = c^2[/tex]

Where (a) and  (b) are the legs or the sides adjacent to the right angle, and (c) is the hypotenuse or the side opposite the right angle. The hypotenuse is always the largest side in a right triangle.

One can substitute in the given sides and solve to prove that the given triangle with the following side lengths (6, 8, 10) forms a right triangle.

[tex](6)^2 + (8)^2 = (10)^2\\\\36 + 64 = 100\\\\100 = 100[/tex]

Thus the given triangle is a right triangle because one can apply the Pythagorean theorem to its side lengths.

The mistake that was made in the given problem was that the person in the given situation set up the equation using the wrong sides, and thus got a wrong result. Therefore, one should select the following option as their answer,

No, she should have added ([tex]6^2[/tex]) and ([tex]8^2[/tex]) and compared that too ([tex]10^2[/tex]).
