There are 70 students in the school band. 40% of them are sixth graders, 20% are seventh graders, and the rest are eighth graders. How many band members are sixth graders? How many band members are seventh graders? What percentage of the band members are eighth graders?

Answers

Answer 1

Answer:

The band members of sixth graders are 28.

The band members of seventh graders are 14.

The percentage of the  band members eighth graders are 40% .

Step-by-step explanation

Formula

[tex]Percentage = \frac{Part\ value\times 100}{Total\ value}[/tex]

As given

There are 70 students in the school band.

40% of them are sixth graders, 20% are seventh graders, and the rest are eighth graders.

Now first find out the  band members are sixth graders .

Percentage = 40%

Total value = 70

Put in the formula

[tex]40 = \frac{Number\ of\ band\ members\ are\ sixth\ graders\times 100}{70}[/tex]

[tex]Number\ of\ band\ members\ are\ sixth\ graders = \frac{40\times 70}{100}[/tex]

[tex]Number\ of\ band\ members\ are\ sixth\ graders = \frac{2800}{100}[/tex]

[tex]Number\ of\ band\ members\ are\ sixth\ graders = 28[/tex]

Therefore the number of band members are from sixth graders are 28 .

Now first find out the  band members are seventh graders .

Percentage = 20%

Total value = 70

[tex]20 = \frac{Number\ of\ band\ members\ are\ seventh\ graders\times 100}{70}[/tex]

[tex]Number\ of\ band\ members\ are\ seventh\ graders = \frac{20\times 70}{100}[/tex]

[tex]Number\ of\ band\ members\ are\ seventh\ graders = \frac{1400}{100}[/tex]

[tex]Number\ of\ band\ members\ are\ seventh\ graders = 14[/tex]

Therefore the number of band members are from seventh graders are 14.

Now find out the percentage of the eighth graders of the band members.

Total number of band members = sixth graders members + seventh grade members + eighth graders members

As  sixth graders members =  28

seventh grade members = 14

Total number of band members = 70

Put in the above

70 = 28 + 14  + eighth graders members

70 - 42 = eighth graders members

28 = eighth graders members

Put in the percentage formula

[tex]Percentage = \frac{28\times 100}{70}[/tex]

[tex]Percentage = \frac{2800}{70}[/tex]

Percentage = 40%

Therefore the percentage of the band members are eighth graders is 40 %.


Answer 2

Answer:

The band members of sixth graders are 28.

The band members of seventh graders are 14.

The percentage of the  band members eighth graders are 40% .

Step-by-step explanation

Formula

As given

There are 70 students in the school band.

40% of them are sixth graders, 20% are seventh graders, and the rest are eighth graders.

Now first find out the  band members are sixth graders .

Percentage = 40%

Total value = 70

Put in the formula

Therefore the number of band members are from sixth graders are 28 .

Now first find out the  band members are seventh graders .

Percentage = 20%

Total value = 70

Step-by-step explanation:

Therefore the number of band members are from seventh graders are 14.

Now find out the percentage of the eighth graders of the band members.

Total number of band members = sixth graders members + seventh grade members + eighth graders members

As  sixth graders members =  28

seventh grade members = 14

Total number of band members = 70

Put in the above

70 = 28 + 14  + eighth graders members

70 - 42 = eighth graders members

28 = eighth graders members

Put in the percentage formula

Percentage = 40%

Therefore the percentage of the band members are eighth graders is 40 %.

Carolina is mowing lawns for a summer job. For every mowing job, she charges an initial fee plus \$6$6 for each hour of work. Her total fee for a 44-hour job, for instance, is \$32$32. Let F(t)F(t) denote Carolina's fee for a single job FF (measured in dollars) as a function of the number of hours tt it took her to complete it.

Answers

Answer:

y=8+6t

Step-by-step explanation:


Answer:

[tex]F(t)=6t+8[/tex].

Step-by-step explanation:

Let t represent number of hours.

We have been given that Carolina charges $6 for each hour of work. So amount charged for t hours of work would be [tex]6t[/tex].

Let us find initial cost by subtracting charges for 4 hours from 32 as:

[tex]\text{Initial cost}=32-4\times 6[/tex]

[tex]\text{Initial cost}=32-24[/tex]

[tex]\text{Initial cost}=8[/tex]

The total cost for t hours of work would be initial cost plus cost per hour: [tex]6t+8[/tex].

Our required function would be [tex]F(t)=6t+8[/tex].

A gardener is planting two types of trees: Type A is 8 feet tall and grows at a rate of 3 inches per year. Type B is 7 feet tall and grows at a rate of 4 inches per year. Algebraically determine exactly how many years it will take for these trees to be the same height.

Answers

Answer:

Exactly 12 years it will take for these trees to be the same height

Step-by-step explanation:

Slope intercept form: An equation of line is in the form of [tex]y = mx+b[/tex] where m is the slope or unit rate and b is the y-intercepts.

Let x represents the time in years and y represents the height of the tree.

Use conversion:

1 ft = 12 inches

As per the given statement:

Type A is 8 feet tall and grows at a rate of 3 inches per year.

⇒unit rate per year = 3 inches = [tex]\frac{1}{4}[/tex] ft

Then, we have;

[tex]y =\frac{1}{4}x + 8[/tex]                      ......[1]

Similarly for;

Type B  is 7 feet tall and grows at a rate of 4 inches per year.

⇒unit rate per year = 4 inches = [tex]\frac{1}{3}[/tex] ft

then;

[tex]y =\frac{1}{3}x + 7[/tex]                   .....[2]

To find after how many years it will take for these trees to be the same height.

Since, trees to be the same height;

⇒equate [1] and [2], to solve for x;

[tex]\frac{1}{4}x + 8 = \frac{1}{3}x +7[/tex]

Subtract 7 from both sides we get;

[tex]\frac{1}{4}x + 8-7= \frac{1}{3}x +7-7[/tex]

Simplify:

[tex]\frac{1}{4}x + 1= \frac{1}{3}x[/tex]

Subtract [tex]\frac{1}{4}x[/tex] from both sides we get;

[tex]1= \frac{1}{3}x-\frac{1}{4}x[/tex]

Simplify:

[tex]1 = \frac{x}{12}[/tex]

Multiply both sides by 12 we get;

x = 12

Therefore, exactly it will take for these trees to be the same height is, 12 years

An object moves according to the law s = t2 + 5t - 8. what is the exact rate of change of s with respect to t when t = 1.5 seconds?

Answers

Answer:

ds/dt =8  when t =1.5

Step-by-step explanation:

s = t^2 + 5t - 8

We want to find ds/dt

ds/dt = 2t +5

evaluated when t=1.5

ds/dt = 2(1.5) +5

ds/dt = 3+5

ds/dt =8  when t =1.5

Replace t with 1.5 seconds and solve for s:

s = 1.5^2 + 5(1.5) -8

s = 2.25+7.5-8

s= 9.75 -8

s = 1.75


Rate of change is S/t

Rate of change = 1.75 / 1.5

Rate of change of s = 1.17


Solve the quadratic equation by completing the square.

2x² - 20x + 48 = 0

Answers

Steps

So firstly, we need to isolate the x terms onto one side. To do this, subtract 48 on both sides of the equation:

[tex]2x^2-20x=-48[/tex]

Next, divide both sides by 2:

[tex]x^2-10x=-24[/tex]

Next, we are gonna make the left side of the equation a perfect square. To find the constant of this soon-to-be perfect square, divide the x coefficient by 2 and then square the quotient. Add the result onto both sides of the equation:

[tex]-10 \div 2=-5\\(-5)^2=25\\\\x^2-10x+25=1[/tex]

Now, factor the left side:

[tex](x-5)^2=1[/tex]

Next, square root both sides of the equation:

[tex]x-5=\pm 1[/tex]

Next, add 5 to both sides of the equation:

[tex]x=5\pm 1[/tex]

Lastly, solve the left side twice -- once with the plus sign and once with the minus sign.

[tex]x=6,4[/tex]

Answer

In short, x = 6 and 4

Answer: x = 4   x = 6

Step-by-step explanation:

2x² - 20x + 48 = 0

2x² - 20 x + _____ = -48 + ______      subtracted 48 from both sides

2(x² - 10x + _____ ) = 2(-24 + _____ )   factored out 2 from both sides

x² - 10x + _____  = -24 + _____          divided both sides by 2

x² - 10x + 25  = -24 +25          added 25 to both sides

       ↓        ↑            ↑

     [tex]\dfrac{-10}{2}=(-5)^2[/tex]     [tex]\bigg(\dfrac{b}{2}\bigg)^2[/tex] makes a perfect square

(49+7x) -64


Lets simplify the numerator

((6x+9) (x+12) -sqrt(49+76) ^2

Simplify what is inside the last parentheses

((6x+9) (x+12) -sqrt(125) ^2

Squaring a square root leaves the original number

((6x+9) (x+12) -(125)

FOIL the first two terms

First 6x*x = 6x^2

Outer:  6x*12 = 72x

Inner: 9x

Becki put some stamps into her stamp collection book she put 14 stamps on each page if she completely filled 16 pages how many stamps did she put in the book?

Answers

Answer:

224 stamps.

Step-by-step explanation:

We have been given that Becki put 14 stamps on each page.

To find the total number of stamps that Becki put in the book we will multiply the number of stamps put on each page by the number of completely filled pages.

[tex]\text{The total number of stamps in the book}=14\times 16[/tex]

[tex]\text{The total number of stamps in the book}=224[/tex]

Therefore, Becki put 224 stamps in the book.

To find out how many stamps Becki added to her collection, we multiply the number of stamps per page, which is 14, by the number of filled pages, which is 16, resulting in a total of 224 stamps.

To determine how many stamps Becki put into her stamp collection book, we need to calculate the total number of stamps populated over the completely filled pages. She placed 14 stamps on each page and filled 16 pages. The total number of stamps is the product of the number of stamps on each page and the number of pages filled.

The formula we will use is:

Total stamps = Number of stamps per page x Number of filled pages

Substituting the given values:

Total stamps = 14 stamps/page x 16 pages = 224 stamps

Therefore, Becki put 224 stamps in her stamp collection book.

Use the substitution method to solve the system of equations

You solve the substitution method to solve a system of equality by expressing one variable in terms of the other using one equation, and then plugging this expression in the other(s).

In this case, the first equation gives us a way to express n in terms of m. So, we can replace every occurrence of n in the second equation with the given formula.

The result is

[tex] 14m+2n=-8 \iff 14m+2(-7m-4)=-8 \iff 14m-14m-8=-8 \iff -8=-8 [/tex]

So, the second equation turned to be an equality, i.e. an equation where both sides are the same.

This implies that the system has infinitely many solutions, because every couple [tex] (n,m) [/tex] such that [tex] n=-7m-4 [/tex] is a solution to the system, because it satisfies both equations: the first is trivially satisfied, whereas the second is an identity, and as such is satisfied by any value of the variable.

Drag one model next to each situation. The correct model for each group represents that situation

Answers

Final answer:

The question involves creating and analyzing scientific models, collaborating in groups to build and refine these models based on experimental evidence, and engaging in critical thinking about their accuracy and limitations.

Explanation:

The question involves students creating and analyzing models that represent certain scientific situations. Creating a model is a fundamental part of scientific inquiry as it helps in visualizing and understanding complex concepts. Students are tasked with exchanging and labeling pictures or drawings of their models, which aids in the development of the communication of scientific ideas. They then apply their models to specific situations, test these models, and note the outcomes to assess the accuracy and limitations of the models they have built. This process involves critical thinking, collaboration, and application of scientific knowledge.

Moreover, students are required to modify their models based on experimental evidence and discussions about the limitations of their models. When building models of atoms, for example, students must consider basic ratios, an understanding of atomic structure, and the unique characteristics of the element they are representing.
