use your number sense to find the values for x and y that satisfy the equations2x=8​

Answer:

The answer is D brother

Step-by-step explanation:

First, convert the 6 by 8 into inches: 96 by 72 which equals 6912. Now take 6912 and divide it by 4 (for the individual squars) and you get: 1728

A = L x W

A= 8 x 6

A= 96 x 72

96 x 72 = 6912

6912 / 4" = 1728

If your teachers mean like mine, they make you write it out like this:)

Hope that clears it up:)

By taking the quotient between the area of the quilt and the area of a single patch, we will see that she needs 432 patches.

To get this, we need to find the quotient between the surface area of the quilt and the area of a patch.

The quilt is 6ft by 8ft, then the area is:

A = 6ft*8ft = 48ft^2

Remember that:

1ft = 12 in

1ft^2 = (12 in)^2 = 144 in^2

Then the area in square inches is:

A = 48ft^2 = 48*(144 in^2) = 6,912 in^2

Now, the patches are squares of sidelength of 4 inches, then the area of each patch is:

a = (4 in)^2 = 16 in^2

The quotient between the areas gives:

A/a = (6,912 in^2)/(16 in^2) =432

This means that Sarah needs 432 patches, so the correct option is C.

Answer:

The amount of money in Victoria's account at the end of n-th year will be,

$ [tex] (965 \times (1.02)^{(n -1)} - 765)[/tex]

Step-by-step explanation:

The amount of money in Victoria's account at the end of n-th year will be,

$ [tex](200\times (1.02)^{(n-1)} + 15 \times ((1.02)^{(n-1)} + (1.02)^{(n -2)} + (1.02)^{(n-3)} + ........ + (1.02)))[/tex]

= $ [tex](200 \times (1.02)^{(n -1)} + 15 \times \frac{1.02 \times ((1.02)^{(n-1)} - 1)}{0.02})[/tex]

= $ [tex](200 \times (1.02)^{(n -1)} + 15 \times 51 \times ((1.02)^{(n-1)} - 1))[/tex]

= $ [tex] (965 \times (1.02)^{(n -1)} - 765)[/tex]

Since, the interest is compounded over that $ 200 (which was there in the account at the end of 1st year) for (n-1) years and for (n-1) years, (n-2) years, (n -3) years, ...... 1 year respectively over those $ 15 which are deposited in the account at the end of 1 , 2, 3, ...... (n-1) years.

Answer:

[tex]a_{n}=\left [ a\left ( n-1 \right )+15 \right ]*1.02\\[/tex]

Step-by-step explanation:

1) A Recursive formula always makes reference to the previous term, written as a function.

2) From $200 to $215 there was a 7.5% growth, so since the question states that from the beginning of the second year there will be a regular growth.

3) Since it is 2% of interest compounded annually q=1+ 0.02.

[tex]A=215(1+\frac{0.02}{1})^{1}\\A=219.3[/tex]

Or simply

215*1.02=219.3

4) We can write a Recursive formula this way:

[tex]a(n)=215[/tex]

[tex]a(n)=a(n-1)(1.02)[/tex]

5) But since we have a pattern, She will deposit $15 yearly then we must make a little adjustment then add $15. to that. Considering the first term to be 200

[tex]a_{n}=\left [ a\left ( n-1 \right )+15 \right ]*1.02\\a_{1}=200[/tex]

Answer:

y = 8 + 80x

Step-by-step explanation:

Given,

The equation is, y = 8x + 80

It is the wrong equation. Because John has $8 in his bank when he gets a job. It means it is fixed. On the other hand, since he begins earning $80 per day. It becomes variable earnings for him. We know that variables (x, y, z) are multiplied by the variable number (If there is no value for variables). Therefore, the equation will be =

As $8 is fixed and $80 is a variable earnings,

y = 8 + 80x

Here, x represents the number of days John will work. If he works for 20 days, the value will be changed for the number of days he earns. The fixed amount will never be changed.

Answer:

The answer for A. Would be 1 mile B. 2mph C. 4mph and the rest Im still working on

Step-by-step explanation:

Answer:

According to the graph, after half hour, Danielle was 1 mile far from home.

To find the speed we have to apply the formula:

[tex]s=\frac{\Delta d}{\Delta t}[/tex]

From [tex]t=0[/tex] and [tex]t=1[/tex], Danielle went from [tex]d=0[/tex] to  [tex]d=2[/tex]. Replacing this values, we calculate the speed:

[tex]s=\frac{\Delta d}{\Delta t}\\s=\frac{2-0}{1-0}=2[/tex]

Therefore, the speed between 0 and 1 hour is 2 miles per hour.

The Danielle's speed between 1 and 2 hours is zero ([tex]s=0[/tex]). Because, according to the graph, during this time, Danielle didn't move, and without move, there's no speed.

The domain when the function is increasing refers to the increasing x intervals.

From the graph, this increasing interval is from 0 to 1 hours only, it's the only period of time when Danielle was increasing her position.

The parts of the decreasing domain are:

In the graph, you can see these decreasing intervals, which are characterized by a downwards direction of the line.

The parts where the function is constant:

Constant intervals, means no increase, no decrease, just an horizontal line.

The next higher million is 68 million.

The next lower million is 67 million.

67,492,384 is closer to 67 million than to 68 million.

So the nearest million is 67,000,000 .

To round 67,492,384 to the nearest million, round the millions place up by 1 because the digit to its right is 7.

To round 67,492,384 to the nearest million, we need to consider the digits in the millions place and the digit to its right. In this case, the digit in the millions place is 6, and the digit to its right is 7. Since 7 is greater than or equal to 5, we round the millions place up by 1. Therefore, 67,492,384 rounded to the nearest million is 68,000,000.

A) 8.8 × 10^15 kilograms is the right answer

Step-by-step explanation:

Given

Mass of Phobos = [tex]10.8 * 10^{15}\ kg[/tex]

Mass of Deimos = [tex]2.0 * 10^{15}\ kg[/tex]

In order to find how greater is the mass of Phobos from Deimos, the smaller mass will be subtracted from the larger mass

So,

[tex]= 10.8*10^{15} - (2.0*10^{15})[/tex]

As the exponents are same, the numbers can be subtracted directly

[tex]=(10.8-2.0) * 10^{15}\\= 8.8*10^{15}\ kg[/tex]

Total coins = 70

1 dime = 10 cents

1 quarter = 25 cents

Let,

Dimes = x

Multiplying Eqn 1 by 10;

[tex]10(x+y=70)\\10x+10y=700\ \ \ Eqn\ 3[/tex]

Subtracting Eqn 3 from Eqn 2

[tex](10x+25y)-(10x+10y)=1045-700\\10x+25y-10x-10y=345\\15y=345[/tex]

Dividing both sides by 15;

[tex]\frac{15y}{15}=\frac{345}{15}\\y=23[/tex]

Putting y=23 in Eqn 1

[tex]x+23=70\\x=70-23\\x=47[/tex]

Answer:

The largest number of identical cubes whose volumes are whole numbers  that would fit in a cube of volume 1080 [tex]cm^{3}[/tex] is 10.

Step-by-step explanation:

Given that volume of larger cube is 1080[tex]cm^{3}[/tex]

To find number of smaller cube with volume as whole numbers can fit the larger cube:

Imagine Rubik's cube of 3x3 as larger volume and one piece of Rubik's cube is smaller cube. On one edge, three smaller cube with volume

In the same way,

Assuming one edge has 'x' number of cube with volume as whole numbers

Since, It is cube. Number of cube in other edges will be 'x' too

For smaller cube,

Take one side of smaller cube as x

Therefore, One side of larger cube will be nx

For cube,  length = height = breath =nx

The volume of larger cube : [tex](nx)^{3} =1080[/tex]

nx=10.2598cm

we need to find the "largest" number of cube( i.e n )

Therefore, Side x will be smallest and n will be largest.

For smallest value of x,

It is also said that " volumes are whole numbers "

smallest whole number is 1

Thus,

nx=10.2598cm

n=10.2598

n is also whole number so that n=10

The largest number of identical cubes whose volumes are whole numbers  that would fit in a cube of volume 1080 [tex]cm^{3}[/tex] is 10.

Answer:

f(x) = (2/3)x + 4

Step-by-step explanation:

An equation in function is found by isolating y, and changing "y" to "f(x)".

Isolate y by moving everything else to the other side

What is done to one side must be done to the other

6y - 4x = 24

6y - 4x + 4x = 24 + 4x          (add 4x to both sides. -4x +4x cancels out)

6y = 24 + 4x

6y/6 = 24/6 + 4x/6             (divide both sides by 6)

y = 4 + (2/3)x          (simplify)

y = (2/3)x + 4        (rearrange to a familiar format "y=mx+b")  

f(x) = (2/3)x + 4        (replace y with f(x))

The value of the number is 7 . There are many different ways to define an equation. The definition of an equation in algebra is a mathematical statement that demonstrates the equality of two mathematical expressions.

Two expressions joined by the equals symbol ("=") form an equation. [2] The "left hand side" and "right hand side" of the equation are the expressions on either side of the equals sign. The right side of an equation is frequently considered to be zero. Providing the generality is not diminished, this can be achieved by deducting the right-hand side from both sides.

There are many different ways to define an equation. The definition of an equation in algebra is a mathematical statement that demonstrates the equality of two mathematical expressions.

Next, we have to determine the types of inequality symbols that are suitable for this graph, which will be less than and greater than since this is a dashed line graph. We then use the zero-interval test [test point (0, 0)] to ensure whether we shade the opposite portion [portion that does not contain the origin] or the portion that DOES contain the origin. At this step, we must verify the inequalities as false or true:

Answer:

The aquarium can be made by 83 sq. ft. of glass.

Step-by-step explanation:

The public library aquarium is in the shape of a hollow cuboid.

The dimensions of the hollow cuboid are 6 ft by 2.5 ft. by 4 ft.

Now, the total surface area of the aquarium will be given by 2(LW + WH + HL)

Where, L = length = 6 ft, W = width = 2.5 ft and H = height = 4 ft.

If the top of the aquarium is open, then the total surface area will be

= 2(WH + HL) + LW

= 2(2.5 × 4 + 4 × 6) + 6 × 2.5

= 83 sq. ft.

Therefore, the aquarium can be made by 83 sq. ft. of glass. (Answer)

To calculate the square feet of glass used for the aquarium, we find the total surface area of the rectangular prism excluding the top. The total surface area is 83 square feet.

To find out how many square feet of glass were used to build the aquarium, we need to calculate the surface area of the rectangular prism minus the top since it is open.

The surface area of a rectangular prism is given by the formula:

Surface Area = 2lw + 2lh + 2wh

where l is the length, w is the width, and h is the height.

Given the dimensions of the aquarium:

First, we calculate the areas of the sides:

Total surface area excluding the top is:

Total Surface Area = 2lw + 2lh + 2wh - (length * width)

Total Surface Area = 30 + 48 + 20 - (6 * 2.5) = 98 - 15 = 83 square feet

So, 83 square feet of glass were used to build the aquarium.
