$16.75

Step-by-step explanation:

33% of 25 = 8.25. 25 - 8.25 = $16.75

Answer:

16.75

Step-by-step explanation:

Hii :)

First, what is volume?

Volume is a scalar quantity expressing the amount of three-dimensional space enclosed by a closed surface. For example, the space that a substance (solid, liquid, gas, or plasma) or 3D shape occupies or contain

FIRST ONE IS UNDERLINED

Now, lets answer.

Volume = lwh

Surface Area = 2(lw + lh + wh)

So, whats the answer?

Area of the floor is 693 sq ft

--------------Steps--------------

The formula for the area of a rectangle is:

A=l×w

The formula for the volume for a rectangular cube is:

V=l×w×h

We can substitute:

2079ft  3 for V

3ft for h

A for  l×w

And then solve for A  to find the area of the floor: v=l×w×h becomes:

2079ft 3=A×3ft

Therefore,Area of the floor is 693 sq ft

The second question:

8 1/2 is 8.5. 3 1/4 is 3.25

3*8.5*3.25 = 82.875

Answer:214

Step-by-step explanation:$46.12-$29 = $17.12

The daily rate is $29. Maria paid an additional $17.12 for the miles that she drove, at a cost of $.08 per mile.

$17.12 divided by $.08 = 214, therefore, Maria drove 214 miles.

Answer:

210 millimeters

Step-by-step explanation:

There are 10 millimeters in every centimeter.

Width of 4.5cm x 10 = 45 millimeters

Length of 6cm x 10 = 60 millimeters

To figure perimeter, you add all 4 sides.

60 + 60 + 45 + 45 = 210

Perimeter of rectangle = 210 millimeters

The correct option is C.

A rectangle is a type of quadrilateral that has its parallel sides equal to each other and all the four vertices are equal to 90 degrees. Hence, it is also called an equiangular quadrilateral.

Since, the opposite sides are equal and parallel, in rectangle, therefore, it can also be termed as a parallelogram.

Given,

Length of rectangle = 6 cm

Width of rectangle = 4.5 cm

Perimeter of rectangle = 2(length + width)

                                      = 2(6 + 4.5)

                                      = 2(10.5)

                                      = 21 cm

1 cm = 10 mm

Perimeter of rectangle = 210mm

Hence, 210 millimeters is the perimeter of the rectangle.

Answer:

21.08

Step-by-step explanation:

Mean = {Sum of the terms} ÷ {the number of terms}

5 terms 28, 21.8,21.1,19, and 15.5.

Add those which is your sum.

28+21.8+21.1+19+15.5=105.4

So what you do is what i said above which is {Sum of the terms} ÷ {the number of terms}

So.....

105.4 ÷ 5 = 21.08 and that is the answer.

Step-by-step explanation:

For one side of the pyramid:

Since there are two symmetrical triangles on one side of the pyramid, calculate both together as a rectangle.

7x10 = 70cm

There are four equal sides to the pyramid, so multiply the area of one side by 4.

70x4 = 280cm

Finally, calculate the area of the base and add it to the total.

14x14 = 196cm

196+280 = 476cm

Answer:10.816

Step-by-step explanation:

Step 1: First, we will pair the digits of 117 from right to left. Place a horizontal bar to indicate the pairs. 17 is one such pair, which leaves 1 as a single digit in the other pair.

Step 2: Now we will find a number which on multiplication with itself gives a product that is less than or equal to 1. We know, 1 × 1 = 1.

Step 3: Now, we bring down 17 and multiply the quotient by 2. This gives us 2. Hence, 2 is the starting digit of the new divisor.

Step 4: 0 is placed at the units place of the new divisor because when 20 is multiplied by 0, we get 0. The answer obtained now is 17 and we bring down 00.

Step 5: The quotient now becomes 10 and it is multiplied by 2. This gives 20, which becomes the starting digits of the new divisor.

Step 6: 8 is placed at the units place of the new divisor because on multiplying 208 by 8 we get 1664. The remainder obtained is 36 and we bring 00 down.

Step 7: The quotient 108 when multiplied by 2 gives 216, which will be the starting digits of the new divisor.

Step 8: 1 is placed at the units place of the divisor because on multiplying 2161 by 1, we will get 2161. The answer obtained is 1439. Next, we will bring down the next pair of numbers, 00.

Step 9: The quotient 1081 when multiplied by 2 gives 2162, which will be the starting digits of the new divisor.

Step 10: 6 is placed at the units place of the divisor because on multiplying 21626 by 6, we will get 129756. The remainder obtained is 14144. We can bring 00 down and repeat these steps until we get the number we want.

The number of students those who will most likely have their preference  to do their classwork online is 238 out of 350

The Probability in mathematics is the possibility of an event in time. In simple words, how many times that incident is happening in any given time interval.

According to the question statement:

A teacher surveys a random group of students about their preference for doing classwork online or on paper.

17 preferred online and 8 preferred on paper.

To find the number of students who will most likely have their preference to do their classwork online:

We will apply the concept of probability.

Probability(Event) = Favorable Outcomes/Total Outcomes

For the survey,

probability of students preferring online mode of classwork is = 17 /(17+8)

= 17/25

= 0.68

Now if we consider a group of 350 students and probability of students preferring online mode of classwork as 0.68

Let m be the number of students preferring online mode of classwork.

m / 350 = 17/25

m / 350 = 0.68

m = 350 x 0.68

m = 238

Therefore, the number of students are 238.

Answer:

127.23

Step-by-step explanation:

Answer:

The 36 is the total number of choices possible. Two cubes are rolled. If a 1 is rolled on one cube, there are 6 possible choices on the other cube (1, 2, 3, 4, 5, 6). If a 2 is rolled on one cube, there are 6 possible choices on the other cube (1, 2, 3, 4, 5, 6). After doing this for all 6 numbers on the first cube, you find that there are 6+6+6+6+6+6 or 6*6 possible choices. 6*6 is 36, so that is where the 36 is from. You can also use the Fundamental Counting Principle.

Answer: 604,375 = 600,000 + 4000 + 300 + 70 + 5.

Step-by-step explanation: I believe what's tripping you up is the fact that there are 6 digits in the number 604,375, and there are only 5 numbers to write out the actual number in equation form.  The number in between 6 and 4 doesn't count, because if you write it out, it makes 00,000, so there's no point in adding 00,000 when it won't change the equation if you add it.

The question is asking to split the number and write out the digits from the greatest to the least amount of digits.  For example, we're given 4,000, 300, and 5, which each are part of the number 604,375.  600,000 is the answer to the first blank and the blank between 300 and 5 is 70.

Answer:

A)  x-intercepts are (0.6, 0) and (-1, 0)

B)  vertex is (-0.2, -3.2)

C)  see attached

Step-by-step explanation:

Part A

Given function:  [tex]f(x)=5x^2+2x-3[/tex]

The x-intercepts are when f(x) = 0

[tex]\implies 5x^2+2x-3=0[/tex]

To factor, find two numbers that multiply to -15 and sum to 2: 5 and -3

Rewrite the middle term of the quadratic as the sum of these number:

[tex]\implies 5x^2+5x-3x-3=0[/tex]

Factorize the first two terms and the last two terms separately:

[tex]\implies 5x(x+1)-3(x+1)=0[/tex]

Factor out the common term [tex](x+1)[/tex]:

[tex]\implies (5x-3)(x+1)=0[/tex]

[tex]\implies (5x-3)=0\implies x=\dfrac35=0.6[/tex]

[tex]\implies (x+1)=0 \implies x=-1[/tex]

Therefore, the x-intercepts are (0.6, 0) and (-1, 0)

Part B

As the leading coefficient of the quadratic is positive, the parabola will open upwards.  This means that the vertex will be a minimum point.

The x-coordinate of the vertex is the midpoint of the zeros.

[tex]\sf midpoint=\dfrac{-1+0.6}{2}=-0.2[/tex]

To find the y-coordinate of the vertex, substitute the found value of x into the given equation:

[tex]f(-0.2)=5(-0.2)^2+2(-0.2)-3=-3.2[/tex]

Therefore, the vertex is (-0.2, -3.2)

Part C

Plot the zeros and the vertex.

The axis of symmetry is the x value of the vertex, so ensure that the graph is symmetrical about x = -0.2.
