Carlotta has 12 2/3 yd of ribbon to be divided among 19 girls in the cheerleading squad.how much ribbon will each girl get if it is divided equally among the 19 girls

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.

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]

Hence,

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

There are 47 dimes and 23 quarters.

Step-by-step explanation:

Total amount = $10.45 = 10.45*100 = 1045 cents

Total coins = 70

1 dime = 10 cents

1 quarter = 25 cents

Let,

Dimes = x

Quarters = y

According to given statement;

x+y=70   Eqn 1

10x+25y=1045   Eqn 2

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]

There are 47 dimes and 23 quarters.

If we want to cover the base of the prism having dimensions 2 cm × 1 cm with [tex]\frac{1}{2}[/tex] cm length of cube, then there will be (4 × 2) = 8 cubes that can occupy the base.

Width is 1 cm, so there can fit 2 cubes of length [tex]\frac{1}{2}[/tex] cm and length is 2 cm, where 4 cubes of length [tex]\frac{1}{2}[/tex] cm can fit. So, in total (4 × 2) = 8 cubes of [tex]\frac{1}{2}[/tex] cm length.

Now, height of the prism is [tex]\frac{3}{2}[/tex] cm where 3 cubes of length [tex]\frac{1}{2}[/tex] cm can fit.

Step-by-step explanation:

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))

Answer:

3.0 grams of the element are left after 18 minutes

Step-by-step explanation:

Recall that an exponential decay that can be studied with the following formula for the amount of material (A) as a function of time (t):

[tex]A(t)=A_0(1-r)^t[/tex]

where:

[tex]A_0[/tex] is the starting amount of the substance (in our case 820 grams)

r is the rate of decay (which in our case given as 26.8% can be written in decimal form as 0.268

and t is the time in minutes (in our case t = 18 minutes)

Then we have:

[tex]A(t)=A_0(1-r)^t\\A(18)=820*(1-0.268)^18\\A(18)=820*(0.732)^18\\\\A(18)=2.985\,grams[/tex]

which can be rounded to 3.0 grams

Answer: 3.0

Step-by-step explanation:

a=820

r= rate= 26.8%=0.268

b=1-r=1-0.268=0.732

y=820(0.732)^18

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.

Step-by-step explanation:

The length of the midsection is the sum of the two bases divided by 2. Remember that the bases of a trapezoid are the two parallel sides. So that means:

((5x - 11) + (2x + 7)) /2 = 3x + 7

Simplify ((5x - 11) + (2x + 7)) /2:

(5x - 11) + (2x + 7) /2 = (5x + 2x - 11 + 7) /2 = (7x - 4) /2

Therefore:

(7x - 4) /2 = 3x + 7

Now solve this simultaneous equation:

7x - 4 = 6x + 14

7x = 6x + 18

x = 18

Starting from the y-intercept of [tex]\displaystyle [0, -2],[/tex]you do [tex]\displaystyle \frac{rise}{run}[/tex]by either moving four blocks south over one block west or four blocks north over one block east [west and south are negatives]. 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:

Greater than

[tex]\displaystyle 0 > 4[0] - 2 → 0 > -2[/tex]☑

Less than

[tex]\displaystyle 0 < 4[0] - 2 → 0 ≮ -2[/tex]

This graph is shaded in the portion of the origin, so you would choose the greater than inequality symbol to get this inequality:

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 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.

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

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.

The buyer spent $2 per landscaping block.

Firstly, we need to find out how much money was spent on the landscaping blocks. Given that the buyer spent $164 for two loads of mulch at $22.50 per load and $35 worth of flowers, subtract the total cost of the mulch and flowers from the total amount spent. This gives us:

($22.50 x 2) + $35 =$80 spent on mulch and flowers. Therefore, $164 - $80 = $84 spent on landscaping blocks.

Finally, find the cost per block, by dividing the total amount spent on blocks by the number of blocks. So, $84 / 42 blocks = $2 per block.
