Answer: 40%

Step-by-step explanation:

Total students= 240

Dissatisfied students= 96

To get the percentage of sixth grade students that were dissatisfied with the music played in the school, we divide 96 by 240 and multiply the result by 100. This can be written as:

= 96/240 × 100

= 0.4 × 100

= 40%

The percentage represented is 40%

Step-by-step explanation:

The area of hexagon base of hexagonal pyramid is option (A) 374.12 square inches.

A pyramid with a hexagonal base upon which are erected six isosceles triangular faces that meet at a point. All sides are equal, the angles between the sides are 120 degrees.

For the given situation,

The base of the hexagon, a = 12 in

The formula of the area of hexagon base is

[tex]A=\frac{3\sqrt{3}(a)^{2} }{2}[/tex]

On substituting the above values,

⇒ [tex]A=\frac{3\sqrt{3}(12)^{2} }{2}[/tex]

⇒ [tex]A=\frac{3\sqrt{3}(144 )}{2}[/tex]

⇒ [tex]A=374.12[/tex]

Hence we can conclude that the area of hexagon base of hexagonal pyramid is option (A) 374.12 square inches.

Answer:

Step-by-step explanation:

If all faces are equilateral, and they are all congruent, that means the surface area of the pyramid is formed by 4 equal triangles, including the base.

We just need to find the area of one triangle and then multiply it by 4.

According to the image, the height of a triangle face is [tex]h=7.8 \ ft[/tex], and its base is [tex]b=9 \ ft[/tex]. So, the area is

[tex]A=\frac{1}{2} (b \times h)[/tex]

[tex]A=\frac{1}{2}(7.8 \times 9) =35.1 \ ft^{2}[/tex]

Then, the total surface area of the pyramid is

[tex]S=4(35.1)=140.4 \ ft^{2}[/tex]

Therefore, the right answer is B. 140.4 square feet.

Answer:

choice D.) 0.9429

Step-by-step explanation:

Given a Normal data set

mean u = 54

standard deviation s = 3.8

we want P( X > 48)

Standardize this probability so we can use Z-scores.

P( X > 48) = P( (X - u)/s > (48 - 54)/3.8 ) = P(Z >  -1.5789)

so  I look for P ( Z > 1.5789) = 0.0571

so  P(Z > -1.5789) = 1 - P(Z > 1.5789) = 1 - 0.0571 = 0.9429

Answer:

It'll take approximately 9.1 minutes

Step-by-step explanation:

The decay of this element can be modeled by the following expression:

m(t) = 540*(1 - 0.179)^t

Where m is the mass of the element in a given minute t. This expression comes from a compounded interest formula, with negative rate, since they will work in the same manner. Therefore to find how long until it reaches 90 g, we need to make m = 90 and solve for t.

90 = 540*(0.821)^t

(0.821)^t = 90 / 540

(0.821)^t = 1/6

ln(0.821^t) = ln(1/6)

t*ln(0.821) = ln(1) - ln(6)

t*ln(0.821) = - ln(6)

t = -ln(6)/ln(0.821) = 9.08452

It'll take approximately 9.1 minutes

A was wrong I seen the real answer which was C

We have been given that Willy has compounded monthly to invest his summer earnings of $4259 in the  Rock Solid Bank. The bank is offering 6%. We are asked to find the amount of money will be after 5 years.

We will use compound interest formula to solve our given problem.

[tex]A=P(1+\frac{r}{n})^{nt}[/tex], where,

A = Final amount after t years,

P = Principal amount,

r = Annual interest rate in decimal form,

n = Number of times interest is compounded per year.

t = Time in years.

[tex]6\%=\frac{6}{100}=0.06[/tex]

Since interest is compounded monthly, so [tex]n=12[/tex] and [tex]P=4259[/tex].

[tex]A=\$4259(1+\frac{0.06}{12})^{12\cdot 5}[/tex]

[tex]A=\$4259(1+0.005)^{60}[/tex]

[tex]A=\$4259(1.005)^{60}[/tex]

[tex]A=\$4259(1.3488501525493161)[/tex]

[tex]A=\$5744.752799707\approx \$5744.75[/tex]

Therefore, Will will have approximately [tex]\$5744.75[/tex] in 5 years.

Answer:

a) BC = 8.66 feet

b) AD = 21.2134 feet

c) EC = 25.9785 feet

Step-by-step explanation:

a)

To find the length of BC, we just need to use the tangent relation of the angle ABC, where the opposite side is the length of AC and the adjacent side is the length of BC:

tangent(60) = AC / BC

1.7321 = 15 / BC

BC = 15 / 1.7321 = 8.66 feet

b)

To find the length of AD, we just need to use the sine relation of the angle ADC, where the opposite side is the length of AC and the hypotenusa is the length of AD:

sine(45) = AC / AD

0.7071 = 15 / AD

AD = 15 / 0.7071 = 21.2134 feet

c)

Similarly to the procedure in letter a), to find the length of EC, we just need to use the tangent relation of the angle AEC, where the opposite side is the length of AC and the adjacent side is the length of EC:

tangent(30) = AC / EC

0.5774 = 15 / EC

EC = 15 / 0.5774 = 25.9785 feet

Answer:

Because surface area has nothing to do with how tall it is

Step-by-step explanation:

Surface area involves the base shape of the object, if both cylinders have a base of the same size and shape, then the surface area of the face of that object will remain the same. how tall the cylinder is would affect volume however.

Please mark brainliest :)

Answer:

Sample response: The surface area of a cylinder is the sum of the areas of the two bases and the area of the lateral surface. If the height of the cylinder is doubled, the area of the lateral surface is doubled, but the areas of the bases remain the same.Step-by-step explanation:

Answer:

x = sine 70° / 8

Step-by-step explanation:

The best estimate of the lateral area of a cube with 2.1-inch edges is 17.64 square inches, calculated by squaring the edge length to find the area of one side (4.41 square inches) and then multiplying by four since there are four lateral faces.

The question asks for the best estimate of the lateral area of a cube with edges that are 2.1 inches long.

To calculate the lateral area of a cube, we need the formula for the lateral area, which is the sum of the areas of all the sides excluding the top and bottom faces. Since a cube has six faces, we have four lateral faces to consider.

The area of one face of a cube is obtained by squaring the length of one edge. In this case:

Area of one side = edge length × edge length = 2.1 inches × 2.1 inches = 4.41 square inches

Since there are four sides whose areas we need to count for the lateral area, we multiply the area of one side by four:

Lateral area = 4 × Area of one side = 4 × 4.41 square inches = 17.64 square inches

Therefore, the best estimate of the lateral area of the cube is 17.64 square inches.

Final answer:

The best estimate of the lateral area of a cube with 2.1-inch edges is approximately 17.64 square inches, calculated by squaring the edge length and multiplying by four since a cube has four lateral faces.

Explanation:

The goal is to estimate the lateral area of a cube with edges that are 2.1 inches long. The lateral area of a cube is the sum of the areas of all the sides of the cube, excluding the top and bottom faces. Since the cube has six faces and we only need the sides, we calculate for four faces.

Each face of a cube is a square, so to find the area of one face, we square the length of the edge:

Area of one side = Edge length × Edge length

Area of one side = 2.1 inches × 2.1 inches

Area of one side = 4.41 square inches

Since there are four sides whose area we are considering for the lateral area:

Lateral area = 4 × Area of one side

Lateral area = 4 × 4.41 square inches

Lateral area = 17.64 square inches

So, the best estimate of the lateral area of the cube is approximately 17.64 square inches.

5h=12

12/5=2.4

When working together, Jessica and Sydney can construct a bookshelf in 2.4 hours. This is based on their individual rates of work.

This problem involves the concept of rates of work. We need to find out how long it will take for Jessica and Sydney to build a bookshelf together. Jessica builds one bookshelf in 4 hours, so her work rate is 1/4 bookshelves per hour. Sydney builds one bookshelf in 6 hours, hence her work rate is 1/6 bookshelves per hour.

When Jessica and Sydney work together, their work rates add together. So the combined work rate is 1/4 + 1/6 = 5/12 bookshelves per hour. Since they are building just one bookshelf, we can find the time it takes by dividing the number of bookshelves (1) by the work rate (5/12). Therefore, when working together, Jessica and Sydney can build a bookshelf in 12/5 or 2.4 hours.
