Answer:

x = 29.9 ft

Step-by-step explanation:

Given:

Rectangle 1 ≈ Rectangle 2

In Rectangle 1

A = 13.4 ft

B = 4.6 ft

In Rectangle 1

A = 87.1 ft

B = x ft

Find:

Value of x

Computation:

Rectangle 1 ≈ Rectangle 2

So,

13.4 / 4.6 = 87.1 / x

x = [(87.1)(4.6)] / 13.4

x = 29.9 ft

Answer:

Local Grocer store's offer is the better deal

Step-by-step explanation:

In order to calculate which is the better bargain, we need to find out how much each deal is charging for the individual can of tuna. We calculate this by dividing the total of the offer by the number of cans of tuna it includes like so...

Local: $3.28 / 4 = $0.82 per can

Ocean's Best: $1.88 / 2 = $0.94 per can

Therefore, we can see that the Local Grocer store's offer is the better deal since it is selling you each can at 0.82 cents compared to the 0.94 cents that Ocean's Best is charging per can.

It's seastar

Step-by-step explanation: tbh I put in seastar as an answer on ixl and got it correct but if you want to know what you have to all you need to do is divide price by amount and the one with less is the better option for example if you have a 4 pack for $4.56 you would do $4.56/4 price always goes first remember that! :D

Answer:

x = - 4

Step-by-step explanation:

Given

8x - 3 = 5(2x + 1) ← distribute

8x - 3 = 10x + 5 ( subtract 10x from both sides )

- 2x - 3 = 5 ( add 3 to both sides )

- 2x = 8 ( divide both sides by - 2 )

x = - 4

Answer:

x = - 4

Step-by-step explanation:

8x - 3 = 5(2x + 1)

8x - 3 = 5 × 2x + 5 × 1

8x - 3 = 10x + 5

8x - 10x = 3 + 5

- 2x = 8

2x = - 8

x = (- 8)/2

x = - 4

Thus, The value of x is -4

Answer:

Option (A)

Step-by-step explanation:

Surface area of an object = Area of all the surfaces of the object

So, the surface area of the cylinder = Area of the two circular bases + Rectangular area around the surface of the cylinder

= πr²+ πr² + (2πr)h

= 2πr(r + h)

Therefore, Option (A) will be the correct option.

Answer:

  π/3

Step-by-step explanation:

The given integral does not exist. We assume there is a typo in the upper limit, and that you want the integral whose upper limit is (√3)/2.

It is convenient to make the substitution ...

  x = sin(y) . . . . so, y = arcsin(x)

 dx = cos(y)·dy

Then the integral is ...

  [tex]\displaystyle\int_0^{\sqrt{3}/2}{\dfrac{\cos{y}}{\sqrt{1-\sin^2{y}}}}\,dy=\int_0^{\sqrt{3}/2}{dy}=\left.\arcsin{x}\right|\limits_0^{\sqrt{3}/2}\\\\=\arcsin{(\sqrt{3}/2)}=\boxed{\dfrac{\pi}{3}}[/tex]

====================================================

Explanation:

Let's say we have the following code names for each shape

We have 4! = 4*3*2*1 = 24 ways to arrange them without any restrictions

Some permutations have C and S together, while others do not.

Example of them together: CSTP

Example of them separated: CTSP

--------------------------

Let's say Amanda used a rubberband or glue to connect the circle to the square. This way the two shapes would always be together. They combine to form a new shape of sorts.

Let's call this new shape "polygon" and define it as

L = polygon

The codename L is just a placeholder for CS or SC.

So instead of the set of these codenames {C,S,T,P}, we have this reduced set {L,T,P}

No matter how we arrange the items in {L,T,P}, the circle and square are always going to be together. Again, anywhere you see an L, you replace it with CS or SC.

--------------------------

There are 3 letters in {L,T,P} so there are 3! = 3*2*1 = 6 ways to arrange those 3 letters. There are 2 ways to arrange S and C within any of those 6 arrangements mentioned earlier.

So there are 2*6 = 12 different ways to arrange the four shapes such that S and C are together somehow.

Recall earlier we found 24 ways total to arrange the shapes without restriction. This must mean there are 24 - 12 = 12 permutations such that S and C are not together. This is the final answer we're after.

Answer:

Step-by-step explanation:

The slope of the given line can be found from the slope formula:

  m = (y2 -y1)/(x2 -x1)

  m = (4 -1)/(3 -2) = 3/1 = 3

The slope of the perpendicular line is the opposite reciprocal of this:

  perpendicular slope = -1/m = -1/3

__

Choices (c) and (d) have x-coefficients that are -1/3. Those are the perpendicular lines.

Answer:1/2 divided by 10

Step-by-step explanation:

Answer:

Given function:

y=9.5x+62.1

We have to find the number of minutes x, when y=138.1°F

Put value of y in function.

138.1=9.5x+62.1

Subtract 62.1 from both sides.

76=9.5x

Divide both sides by 9.5.

8=x

or

x=8 minutes

Answer:

T= 8n+76

Step-by-step explanation:

First you need to find the average rate of change:

( 3, 100)

(9,148)

Subtract:

148-100= 48

9-3= 6

Then divide them:

48/6=8

This is your slope, now we must find our y- intercept by using the formula

y= mx+b:

y=mx+b

Plug in what you know:

y= 8x+b

To find your y-intercept use one of the 2 points above, either (3,100) or (9,148)

Plug in your x's and y's into your almost complete equation:

100= 8(3)+b

Then solve to get b:

You should get b=76

Answer:

6, 9, 12, 15, 18

Step-by-step explanation:

If the third term is 12, then to find the first term subtract 3 twice (or just subtract 6) to get 6. To find the rest of the terms add 3 accordingly. The equation to find this would be:

a_n = 6 + (n-1)3

15.82x2=31.64

31.64+42.37=74.01

100-74.01=25.99

Step-by-step explanation:

We have,

[tex]f(x) = - 2 \sqrt[3]{x + 7} [/tex]

Taking limit,

[tex] \lim _{x \rarr \infty } f(x) \\ = \lim _{x \rarr \infty } - 2 \sqrt[3]{x + 7} [/tex]

If x approaches to positive infinity,

this implies f(x) approaches to negative infinity

The combination of volumes of bleach and water for Maël's sanitizing solution will be 12 mL of bleach and 3 L water, 6 mL of bleach and 1.5 L water, and 3 mL of bleach and 0.75 L water. Then the correct options are A, B, and C.

Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.

The acronym PEMDAS stands for Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This approach is used to answer the problem correctly and completely.

Maël mixes 15 milliliters of bleach with 3.75 liters of water to make a sanitizing solution for a daycare.

The ratio of bleach to water is given below.

Bleach / Water = 15 / 3.75 = 4

Bleach / Water = 12 / 3 = 4

Bleach / Water = 6 / 1.5 = 4

Bleach / Water = 3 / 0.75 = 4

Bleach / Water = 20 / 5.5 = 3.6363

The combination of volumes of bleach and water for Maël's sanitizing solution will be 12 mL of bleach and 3 L water, 6 mL of bleach and 1.5 L water, and 3 mL of bleach and 0.75 L water. Then the correct options are A, B, and C.

Step-by-step explanation:

I found the graph. All you needed to do was switch the red and blue line. I put a screenshot of the correct answer on I-Ready as well as the graph I had found.

The system of equations needed to solve the given equations is . Thus, the correct graph is the top-right graph. Its plotted below.

An equation usually consists of equality of two mathematical expressions. Let it be [tex]A = B[/tex]. If we take them to be equal to third variable, then:

[tex]A = B = C[/tex] type of equation is obtained.

We can then take it as system of two equations as:

[tex]A = C\\B = C[/tex]

Solution to this system will give us the solution to the considered equation

For a solution to be solution to a system, it must satisfy all the equations of that system, and as all points satisfying an equation are in their graphs.

For the given case, we are given that:

[tex]2^x-1=x+2[/tex]

Taking these two mathematical expression equal to 'y', we get:

[tex]2^x-1=x+2 = y[/tex]

or

[tex]y = 2^x - 1\\and\\y= x+2[/tex]

Plotting these two functions on the X-Y plane, the common point of these curves is the common value which can satisfy both the equations simultaneously, and thus, being the solution to the considered system of equations.

Thus, the solutions are those two points that are intersections of those two curves.
