problem referred below

Answer:

1. Use variables to represent length and width.

width = w

length = w + 5

2. Set up an equation for the perimeter of the rectangle.

perimeter = 2L + 2W

2(w + 5) + 2(w) = 46

2w + 10 + 2w = 46

4w + 10 = 46

4w = 36

w = 9

3. Find the length and width of the rectangle.

width = w = 9 inches

length = w + 5 = 14 inches

Answer:

Width is 9 inches

Length is 14 inches

Step-by-step explanation:

width = w

length = w + 5

perimeter = 2L + 2W

2(w + 5) + 2(w) = 46

2w + 10 + 2w = 46

4w + 10 = 46

4w = 36

w = 9

Width = w = 9 inches

Length = w + 5 = 14 inches

Therefore the width is equal to 9 inches and the length is 14 inches.

Answer:

(4x+3) (x+2)

Step-by-step explanation:

4x times x equals 4x^2

4x times 2 equals 8x

3 times x equals 3x

3 times 2 equals 6

8x plus 3x equals 11x which sums up everything to the equation 4x^2+11x+6

Answer: 7,150 mL

Step-by-step explanation:

Shen drinks 0.55L of milk daily.

In order to find how much milk Shen is drinking in 13 days multiply 0.55 L by 13:

0.55 × 13 = 7.15 L

Turn the Liters into milliliters:

1 liter = 1000 mL

7.15 liters = 7,150 mL

Solution:

The shadow of an object is directly proportional to its height. Thus,

\[\frac{\text{Height of object}}{\text{Length of shadow}} = \frac{6}{16} = \frac{3}{8}.\]

Therefore, the height of the flagpole is $\frac{3}{8} \cdot 72 = \boxed{27}$ feet.

Problem: Report Error

Twelve hungry teenagers can devour a very large pizza in $20$ minutes. How many teenagers would it take to finish a very large pizza in $15$ minutes? (Assume that all teenagers eat pizza at the same rate.)

(Based on Problem 7.5 of the textbook.)

Solution:

Each of the twelve teenagers eats $\frac{1}{12}$ of the pizza in $20$ minutes. Thus, the rate of a teenager is

\[\frac{\frac{1}{12} \text{ pizza}}{20 \text { minutes}} = \frac{1}{240} \ \frac{\text{pizza}}{\text{minute}}.\]

This means in $15$ minutes, each teenager can eat

\[(15 \text{ minutes}) \left( \frac{1}{240} \ \frac{\text{pizza}}{\text{minute}} \right) = \frac{1}{16} \text{ pizza}.\]Therefore, it will take $\boxed{16}$ teenagers.

Alternatively, the number of teenagers is inversely proportional to the time it takes them to finish. From the given information, the constant of proportionality is $12 \cdot 20 = 240.$ Therefore, the answer we seek is $\frac{240}{15} = \boxed{16}.$

Problem: Report Error

For a statue of Miss Levans, the amount of gold required is directly proportional to the square of the height of the statue. A statue of Miss Levans that is $20$ feet tall requires $80$ pounds of gold. How many pounds of gold does a statue that is $25$ feet tall require?

We suggest you study Section 7.1 if you find this problem difficult.

Solution:

Let $h$ be the height of the statue, and let $g$ be the amount of gold required. Then

\[g = kh^2\]for some constant $k.$

Since $g = 80$ when $h = 20,$

\[80 = k \cdot 20^2,\]so

\[k = \frac{80}{20^2} = \frac{1}{5}.\]

So when $h = 25,$

\[g = \frac{1}{5} \cdot 25^2 = \boxed{125}.\]

Hint(s):

Let $h$ be the height of the statue, and let $g$ be the amount of gold required. Then $g = kh^2$ for some constant $k.$ Find $k.$

Answer:

Yes, it is a solution because inserting 8 into the equation gives you 13.

Step-by-step explanation:

The volume [tex]V_s[/tex] of a sphere of radius R is is given by

[tex]V_s = \frac{4\pi}{3}R^3[/tex]

so a hemisphere will only have half the volume of a sphere so we can write its volume [tex]V_h[/tex] as

[tex]V_h = \frac{1}{2}V_s = \frac{2\pi}{3}R^3[/tex]

Since the diameter D is twice the radius R, we can rewrite [tex]V_h[/tex] in terms of D as

[tex]V_h = \frac{2\pi}{3}\left(\frac{1}{2}D\right)^3 = \frac{\pi}{12}D^3[/tex]

[tex]\:\:\:\:\:\:\:=\frac{\pi}{12}(12\:\text{cm})^3 = 452.4\:\text{cm}^3[/tex]

Now represents the amount of water inside the hemisphere, which will be then transferred to a cylinder 8 cm in diameter. The volume of this cylindrical can [tex]V_c[/tex] must equal the volume of the hemisphere:

[tex]V_h = V_c = \pi R^2h = \pi\left(\frac{1}{2}D\right)^2h[/tex]

[tex]\:\:\:\:\:\:\:=\frac{\pi}{4}D^2h[/tex]

where h is the height (or depth) of the can. Solving for h, we get

[tex]h = \dfrac{4V_h}{\pi D^2} = \dfrac{4(452.4\:\text{cm}^3)}{\pi(8\:\text{cm})^2}[/tex]

Answer:

Step-by-step explanation:

It can be helpful to memorize a few of the Pythagorean triples that show up in Algebra problems. Their multiples also form right triangles.

  (3, 4, 5), (5, 12, 13), (7, 24, 25), (8, 15, 17), (9, 40, 41)

The triple (6, 8, 10) is the first one of these, multiplied by 2 inches.

The only triple that is a sequence of consecutive integers is (3, 4, 5), so you know immediately that (4, 5, 6) does not form a right triangle.

Of course, you can check any of them to see if the squares of the smaller two numbers total the square of the larger number:

  4² +5² = 16 +25 = 41 ≠ 6² . . . . . (4, 5, 6) is not a right triangle

Step-by-step explanation:

i think what they want us to do here is round to the nearest tenth. however, as we all know, any number lower than five you must round down and convert to zeros. so, since the prescription called for 1.04 tablets per day, we can round down and get just 1.

so, 1 is your answer.

Answer: I believe the answer would be C, or 1

Step-by-step explanation: If he is supposed to take 1.04 tablets per day, the closest to that would be one tablet, because you can't really cut of 4% of a pill.

The required time to fill the tub is 7.5 minutes.

In order to solve a problem for two different values of a quantity, its unit value is first derived. This method is known as unitary method.

Given that,

The time taken by hose to fill 18-gallon tub is 3 minutes.

So, the time taken by the the same hose to fill 45 gallon can be calculated using unitary method as,

The time it takes to fill 1 gallon is 3/18 = 1/6.

Thus, the time for filling 45 gallon is 1/6 × 45 = 7.5 minutes.

Hence, the time taken by the hose to fill 45 gallon tub is 7.5 minutes.

I find it easier to write the equation if I can find grid intersection points where the line crosses. Here, a couple of them are (1, 1) and (3, 2).

The slope can be found from ...

  m = (y2 -y1)/(x2 -x1)

  m = (2 -1)/(3 -1) = 1/2

The y-intercept can be found from ...

  b = y -mx

  b = 1 -(1/2)(1) = 1/2 . . . . . . using (x, y) = (1, 1)

Then the slope-intercept equation is ...

  y = mx +b

  y = 1/2x +1/2

In standard form, the equation can be written as ...

  x -2y = -1 . . . . . multiply by 2; subtract y+1 from both sides

Step-by-step explanation:

First we recall the relevant definitions and properties:

An even integer is an integer that is a multiple of 2, that is, an integer that can be written as 2k2k where kk is also an integer.

An abelian group is a set with an operation that is closed in that set, is associative, has an identity element, has inverses, and is commutative.

Addition is already associative and commutative over the set of all integers, and has an identity 00 and an inverse −n−n for each integer nn.

Oh, and multiplication of integers distributes over addition (this is important because we’re dealing with multiples of 2 but also with addition. The distributive property is how multiplication relates to addition).

This means we have to show a few things:

Addition is closed over the even integers. This holds due to the distributive property: if you have even integers 2k2k and 2m2m, then 2k+2m=2(k+m)2k+2m=2(k+m) is also an even integer. The odd integers fail this property: for example, 11 is odd but 1+1=21+1=2, which is not odd.

Addition is associative over the even integers. This holds because addition is already associative over the set of all integers: 2k+(2m+2j)=(2k+2m)+2j2k+(2m+2j)=(2k+2m)+2j. The odd integers do satisfy associativity, since they’re also a subset of the integers.

Addition has an identity element over the even integers. Since we already know that 00 is an identity for the set of all integers and 00 is even, this shows that we have an identity for the even integers: 2k+0=2k2k+0=2k. This doesn’t hold for the set of odd integers, because if nn and kk are odd integers and n+k=nn+k=n then k=0k=0, a contradiction since 00 is not odd.

Addition has inverses over the even integers. We already know that integers have inverses, and if 2k2k is an even integer then −k−k is the inverse of kk, so that 2k+2(−k)=2(k+(−k))=2(0)=02k+2(−k)=2(k+(−k))=2(0)=0. This means the even integer 2(−k)2(−k) is the inverse of 2k2k. The odd numbers do satisfy this property, since they’re also a subset of the integers.

Addition is commutative over the even integers. This holds because addition is already commutative over the set of all integers: 2k
