Marlo uses 252 lb of gravel to cover a garden plot of 36 ft2. How many pounds of gravel does it take to cover one square foot? How large an area could be covered with 315 lb of gravel?

Answers

Answer 1

The area and the amount of gravel are illustrations of proportions.

7 lb will cover an area of 1 square foot, while 315 lb will cover an area of 45 square feet.

The given parameters are:

[tex]252\ lb= 36ft^2[/tex]

The number of pound for an area of 1 square foot is calculated as follows:

[tex]x = 1ft^2[/tex]

So, we have:

[tex]x = 1ft^2[/tex]

[tex]252\ lb= 36ft^2[/tex]

Cross multiply

[tex]x \times 36 = 252 \times 1[/tex]

Divide both sides by 36

[tex]x = 7lb[/tex]

The area to be covered with 315lb gravel is calculated as follows:

[tex]315lb = y[/tex]

So, we have:

[tex]315lb = y[/tex]

[tex]252\ lb= 36ft^2[/tex]

Cross multiply

[tex]y \times 252 = 36 \times 315[/tex]

[tex]y \times 252 = 11340[/tex]

Divide both sides by 252

[tex]y = 45[/tex]

Hence, 7 lb will cover an area of 1 square foot, while 315 lb will cover an area of 45 square feet.

Answers

Using infinity limits, the matching pairs are:

A - 3.B - 1.C - 2.D - 4.

The end behavior of a function f(x) is given by:

[tex]\lim_{x \rightarrow \infty} f(x)[/tex]

Function A:

[tex]f(x) = -2x + 3[/tex]

[tex]\lim_{x \rightarrow -\infty} f(x) = \lim_{x \rightarrow -\infty} -2x + 3 = \lim_{x \rightarrow -\infty} -2x = -2(-\infty) = \infty[/tex]

[tex]\lim_{x \rightarrow \infty} f(x) = \lim_{x \rightarrow \infty} -2x + 3 = \lim_{x \rightarrow \infty} -2x = -2(\infty) = -\infty[/tex]

Thus, matches with item 3.

Function B:

[tex]f(x) = x^2 - 6x + 3[/tex]

[tex]\lim_{x \rightarrow -\infty} f(x) = \lim_{x \rightarrow -\infty} x^2 - 6x + 3 = \lim_{x \rightarrow -\infty} x^2 = (-\infty)^2 = \infty[/tex]

[tex]\lim_{x \rightarrow \infty} f(x) = \lim_{x \rightarrow \infty} x^2 - 6x + 3 = \lim_{x \rightarrow \infty} x^2 = (\infty)^2 = \infty[/tex]

Thus, matches with item 1.

Function C:

[tex]f(x) = 1 - x^2 + 2x^3[/tex]

[tex]\lim_{x \rightarrow -\infty} f(x) = \lim_{x \rightarrow -\infty} 1 - x^2 + 2x^3 = \lim_{x \rightarrow -\infty} 2x^3 = 2(-\infty)^3 = -\infty[/tex]

[tex]\lim_{x \rightarrow \infty} f(x) = \lim_{x \rightarrow \infty} 1 - x^2 + 2x^3 = \lim_{x \rightarrow \infty} 2x^3 = 2(\infty)^3 = \infty[/tex]

Thus, matches with item 2.

Function D:

[tex]f(x) = 7 - x^4[/tex]

[tex]\lim_{x \rightarrow -\infty} f(x) = \lim_{x \rightarrow -\infty} 7 - x^4 = \lim_{x \rightarrow -\infty} -x^4 = -(-\infty)^4 = -\infty[/tex]

[tex]\lim_{x \rightarrow \infty} f(x) = \lim_{x \rightarrow \infty} 7 - x^4 = \lim_{x \rightarrow \infty} -x^4 = -(\infty)^4 = -\infty[/tex]

Thus, matches with item 4.

O 4 + 2 x4
o (4 + 2) x4
(4 x 4) + 2

Answers

Answer:

Step-by-step explanation:

the answer is (4 x 4)+2

Answer:

o (4+2) x4   is the expression that means 4 batches of 4+2 teaspoons of vanilla.

Step-by-step explanation:

1c = t(4 + 2) is created as t = tspoon but any letter cna represent and maybe the o means teaspoons so lets compare

we see the brackets on (4+2) x4 and use this. And if you must put a 0 in front then I would also convert to show without 0 and show both

As long as brackets separate the (4x 2) to the 4 batches it becomes a workable expression.

When algebra becomes understandable for multiplying we show 4(4 +2)

because in brackets its always add or subtract, but we recognise mainly as the question is worked out first for one part being  1 cupcake = 1c

so 1c = 4t+2t

then;  4c = 4t+2t

we need to multiply the set as a reverse to usual equations that try to make you find what t or c means.

so as we are not subtracting the numbers either side of the = we can just demonstrate a multiplication

4( 4+2)t = 0(4+2) x 4

Can someone help me with number 36? Tysmmm

Answers

Answer: Never(!) [assuming I understand/interpret the question properly]

Step-by-step explanation: The question wants to know how many months it will take for your neighbor's total cost be the same as yours, with three televisions. One has to interpret "total cost." I deem it to be the total accumulated costs, including installation. If you interpret it as the cost per month, then they charges are the same after the month the installation cast was paid. That's because the satellite provider charges per television, and 3*(13.32) is equal to the same 39.96/month charged by the cable provider. It the questions means total cumulative costs, the satellite customer will never exceed the cable customer's total bill, because of the installation fee ($75 for cable and free for satellite)

B = 3.31662479

rounded to 3.32

Step-by-step explanation:

Pythagorean theorem: [tex]a^{2} + b^{2} = c^{2}[/tex]

A & B = the base and height

C = The diagonal line.

A & B can be base or height. ( base = 2 Height = 3. It can be [tex]2^{2} + 3^{2}[/tex] or [tex]3^{2} + 2^{2}[/tex] )

Because when you add it doesn't matter where each number is put.

I like doing b for the base, because there's a b in base, to make it easier for me. But you can do whatever.

A = 5

B = ?

C = 6

[tex]5^{2} + b^{2} + 6^{2}[/tex]

From here you will solve to get b.

[tex]5*5 + b^{2} = 6 * 6[/tex]

[tex]25 + b^{2} = 36[/tex]

25 - 25 + [tex]b^{2}[/tex] = 36 - 25

[tex]b^{2}[/tex] = 11

To under the exponent you have to [tex]\sqrt[/tex] it.

[tex]\sqrt{b_{2}}[/tex] = [tex]\sqrt{11}[/tex]

Hopping for a great answer.​

Answers

Answer:

ln (1 + sin^2(x)) + C

Step-by-step explanation:

Note that sin(2x) = 2 sin(x) cos(x).

So, the integrand is rewritten as:

(2 sin(x) cos(x)) / (1 + sin^2(x) ).

Now, make the substitution u = sin(x), so that du = cos(x) dx.  Thus, in terms of the variable u, the integrand is

(2 u )/(1 + u^2).

Make another substitution v = 1 + u^2, so that dv = 2 u du, and the integrand in terms of v is

1 / v

Now, we integrate, and then back substitute to write that the indefinite integral is

ln |v| + C = ln |1 + u^2| + C = ln |1 + sin^2(x)| + C + ln (1 + sin^2(x)) +C, since 1 + sin^2(x) + 1 is positive for all real x.

Step-by-step explanation:

[tex]\large\underline{\sf{Solution-}}[/tex]

We have to evaluate the given integral.

[tex] \displaystyle \rm = \int \dfrac{ \sin(2x) }{1 + \sin^{2} (x) } \: dx[/tex]

[tex] \displaystyle \rm = \int \dfrac{2 \sin(x) \cos(x) }{1 + \sin^{2} (x) } \: dx[/tex]

Now let us assume that:

[tex] \rm \longmapsto u = 1 + { \sin}^{2}(x)[/tex]

[tex] \rm \longmapsto \dfrac{du}{dx} = 2 \sin(x) \cos(x) [/tex]

[tex] \rm \longmapsto dx = \dfrac{1}{2 \sin(x) \cos(x) } \: du[/tex]

Therefore, the integral becomes:

[tex] \displaystyle \rm = \int \dfrac{1}{u} \: du[/tex]

[tex] \displaystyle \rm = \ln(u) + C[/tex]

[tex] \displaystyle \rm = \ln(1 + sin^{2}x ) + C[/tex]

Therefore:

[tex] \displaystyle \rm \longmapsto \int \dfrac{ \sin(2x) }{1 + \sin^{2} (x) } \: dx = \ln(1 + sin^{2}x ) + C[/tex]

https://www.nysedregents.org/algebratwo/619/algtwo62019-mrs.pdf

The number of years it will take for  1/10 of this substance to remain is; 50 years

What is the half life formula?

The half life formula is;

N(t) = N₀(¹/₂)^(t/t_1/2)

where;

N(t) is quantity of the substance remaining

N₀ is initial amount of substance

t is time elapsed

t_1/2 is half life

Thus;

S(t) = 200(¹/₂)^(t/15)

We want to find the time it will take 1/10 of the substance to remain. Thus;

1/10 = (200/200)(¹/₂)^(t/15)

1/10 = (¹/₂)^(t/15)

t/15 = In(1/10)/In(¹/₂)

t/15 = 3.32193
