bottom:7/10

0.7 = 7/10 because 7 is under tens.  If it was 0.34 = 34/100 because 34 is in the hundereds.  If it was 0.100 = 100/1000 because 100 is under the thousands.  pls brainly trying to level up

Step-by-step explanation:

Explanation

Given: You choose the four packages of modeling clay and the set of equipment indicated on the right for a creative project.

To find: the total cost if there is a 6% sales tax.

We will calculate the total cost of each item and then add.

Tip

The total cost formula is used to combine the variable and fixed costs of providing goods to determine a total.

The formula is: Total cost = (Average fixed cost x average variable cost) x Number of units produced.

Step 1

The cost of 4 packets of clay is given by:

4 x $2.79



Step 2

We will calculate the product:

4 x 2.79 = 11.16

Step 3

We will add the cost of 4 packets of clay and a pack of tools to get the total cost without tax:

$(11.16 + 1.79)



Step 4

We will add the numbers:

11.16 + 1.79 = 12.95

Step 5

The 6% tax on the total price is given by:

6% x $12.95

Step 6

We will calculate the sales tax:

6/100 x 12.95 = 0.777



Step 7

We will add the total cost without tax and tax amount to get the total amount paid:

$(12.95 + 0.777)



Step 8

We will add the amounts:

12.95 + 0.777 = 13.727

Step 9

Answer:

One gets  Rs 24 and the other Rs 96.

Step-by-step explanation:

Number of parts = 1 + 4 = 5

So one student gets 1/5 of 120 and the other gets 4/5 of 120

120 * 1/5 = 24

120 *4/5 =  4*24 = 96.

Answer:

One would get 96 and another would get 24

Step-by-step explanation:

So first lets create an equation from the words where 4x is what one students has and x is what another has :

120 = 4x + x

Lets solve this now!

120 = 5x (divide by 5 on both sides)

24 = x (1st Student)

(Multiply by 4 on both side to get the second student)

96 =4x (2nd Student)

Answer:

Step-by-step explanation:

Part A

The probability of finding a red marble. P(red) = red / total

Total = red +  yellow +  blue

Total = 2 + 4 + 3

Total = 9

P(red) = 2/9 = 0.22222

Part B

P(blue) = blue / total

P(blue) = 3/8 = 0.375

This  means that the red marble is permanently gone. The total is different. It is eight not nine.

Part C

The probability of red followed by blue is just the answers to A and B multiplied.

P(red) followed by blue = 2/9 * 3/8

P(red) followed by blue = 0.22222 * 3.75

P(red) followed by blue = 0.0833333

If you are confident of your concellation abilities you could do this as

P(red followed by blue) = 2/9 * 3/8 = 1/3 *1/4 = 1/12 = 0.083333....

Part D

Removing the first marble had the affect of reducing the total number of marbles to 8 and the number of reds from 2 downto 1

Part E

The answer here is 1/12.

Answer: x<17.5

Step-by-step explanation:

Subtract  from both sides: x+2.5-2.5<20-2.5

Simplify the arithmetic: x<20-2.5

Simplify the arithmetic: x<17.5

Hope it helps!

Answer: B) 12.5

Step-by-step explanation:

Start by isolating x by subtracting 2.5 from both sides

[tex]x+2.5 < 20\\x+2.5-2.5 < 20-2.5\\x < 17.5[/tex]

This reads as "x is less than 17.5"

D can be eliminated because it is greater than 17.5

C can be eliminated because 17.5 can't be less than itself

So the answer must be B since it is less than 17.5 and greater than A

Answer:

A

Step-by-step explanation:

Now when I think of solving it, I think of finding the zeros.  Now if you start with the form, for example:

[tex](x+3)(x-3)[/tex]

Then you can easily see the zeros are -3 and 3.

But if you start with the standard form:

[tex]ax^2+bx+c=0\\or\\x^2-9[/tex]

It will be harder to find the zeros and you would do the eqation or factor it.

So if your in the factored form don't go to standard to find the zeros.

The given statement is False.

An equation with highest degree two, is considered as a quadratic equation.

In standard form, the right side of an equation should be 0 and every component on the left side should be 1.

For example, x² = 4; to express this in standard form, move the number 4 to the left side of the equation, resulting in x² - 4 = 0.

If you are asked to find x in this circumstance, there is no need to write the equation in standard form; simply take this same real number of both of the equation's sides to find x.

Hence, it is not always necessary to write the quadratic equation in standard form then solve.

Answer:

Area = 21.7 cm² (nearest tenth)

Step-by-step explanation:

A 30-60-90 triangle is a special right triangle.  The measures of its sides have a special relationship in that they are in proportion:

shortest leg : longest leg : hypotenuse =  1 : √3 : 2

So we can also write the ratio as  [tex]x : x\sqrt{3} : 2x[/tex]  where [tex]x[/tex] is the shortest side.

From inspection of the diagram, the shortest side is 5 cm

⇒ BC (height) = 5 × √3 = 5√3 cm

Now we have the height, we can calculate the area.

Area of a triangle = 1/2 x base x height

                             = 1/2 x 5 x 5√3

                             = 21.7 cm² (nearest tenth)

The representation of the volume of the prism in greatest to least volume is third > first > second.

Volume is the scalar quantity of any object that specified occupied space in 3D.

For example, the space in our room is referred to as volume.

As per the given cuboid prism.

The volume of the cuboid = length × height × width.

First cube = 1/4 x 3 x 6 x 2 = 9 units³

Second cube = 1/2 x 2 x 3 x 1 = 3 units³

Third cube = 1/8 x 8 x 11 x 4 = 44 units³

So, 44 > 9 > 3.

Hence "The representation of the volume of the prism in greatest to least volume is third > first > second".

Step-by-step explanation:

Answer:

x = -7

Step-by-step explanation:

First step is to expand the left side of the equation. To do this, multiple 4 by each term on the inside of the paratheses.

4 * 2x = 8x

4 * 14  = 56

This gives you the equation:

8x + 56 = 0

Now, get the x term on one side by itself by subtracting 56 on both sides:

8x = -56

And solve for x by dividing both sides by 8:

x = -7

So the volume is 15.84 cm The formula for the volume of a prism is given by the product of the area of the base and height of the prism. Thus, the volume of a prism can be given as V = B × H where V is the volume, B base area, and H height of the prism.

The mean, median and range of the given data are respectively; 49, 48 and 3.

Formula for mean is;

Mean = Total sum/sample size

Total sum = 48 + 51 + 48 + 48 + 50

Total sum = 245

Sample size = 5

Mean = 245/5

Mean = 49

To get the median, we arrange in ascending order and pick the mid term.

48, 48, 48, 50, 51

Median is mid term which is 48.

Range is difference between highest and lowest term.

Range = 51 - 48

Range = 3

If the company wants to keep its production costs under $781.12 a reasonable domain for the constraint x is  -12.9892≤ x ≤ 1012.99.

A constraint is a condition of an optimization problem that should be satisfied the condition.

Let  x is an element of a subset of the integers,

C(x) is the production cost, in thousands of dollars

[tex]C(x) = 50 +3.8x -0.0038x^2,[/tex]

This is a vertical parabola open downward (the leading coefficient is negative)

we know that

For the interval [-12.9892, 1012.99] = -12.9892≤ x ≤ 1012.99

The value of C(x) = C(x) < 781.12

That means the production cost is under $781.12

Remember that the variable x (number of tires) cannot be a negative number.
