If the price of upholstery fabric is $12.49 per yard, how much will 16 yards cost? A. $201.04 B. $199.94 C. $199.84 D. $189.84

Answers

Answer 1

Answer:

c

Step-by-step explanation:

16X12.49=199.84

Answer 2

For this case we can raise a rule of three:

$ 12.49 ---------------> 1 yard

x -------------------------> 16 yards

Where the variable "x" represents the cost of the 16 yards.

[tex]x = \frac {16 * 12.49} {1}\\x = 199.84[/tex]

Thus, the cost of the 16 yards will be 199.84 dollars.

Answer:

Option C

A bookstore has a sale: Jen wants to buy four books: for $10.00, for $12.00, for $15.00, and for $20.00. What is the smallest she could pay for these books during the sale? By what percent would the sale reduce the total cost of these four books?

Answers

Answer:

$47, 17.5%

Step-by-step explanation:

When she buys the $20 book, she can get 40% off either the $15, $12, or $10 book.  She'll save the most by getting 40% off the $15 book.

Then, when she buys the $12 book, she'll get %40 off the $10 book.

The total she pays is:

20 + (0.60)(15) + 12 + (0.60)(10)

20 + 9 + 12 + 6

47

Without the discounts, the cost of the books would have been:

20 + 15 + 12 + 10

57

So she saves $10.  10 out of 57 is approximately 17.5%.


Which equation represents the hyperbola (y -2)^2/4 - (x-2)^2/9=1
in general form?

Answers

Answer:

[tex]9y^2-4x^2-36y+16x-16=0[/tex]

Step-by-step explanation:

The given hyperbola has equation:

[tex]\frac{(y-2)^2}{4}-\frac{(x-2)^2}{9}=1[/tex]

We multiply through by 36 to get:

[tex]9(y-2)^2-4(x-2)^2=36[/tex]

We expand to get:

[tex]9(y^2-4y+4)-4(x^2-4x+4)=36[/tex]

[tex]9y^2-36y+36-4x^2+16x-16=36[/tex]

[tex]9y^2-36y-4x^2+16x-16=0[/tex]

What is the volume, in cubic units, of a pyramid of height 8 and a square base of length 15?

Answers

Answer:

900 cuboc unit

Step-by-step explanation:

Volume of pryamid= 1/3× area× height

= 1÷3×15^15×8

= 900cubic unit

For this case we have by definition, that the area of a square base pyramid is given by:

[tex]V = \frac {L ^ 2 * h} {3}[/tex]

Where:

L: It's the side of the square base

h: It's the height of the pyramid

We have that[tex]L = 15 \ units[/tex], then [tex]L ^ 2 = 15 ^ 2 = 225 \ units ^ 2[/tex]

Answers

Answer: W = 700 divided by a+18

Step-by-step explanation:

a) We can plug in $358 into A(w), since A(w) represents the amount of money Dale needs. So,

358 = 700 - 18w

Subtract: -342 = -18w

Divide: w = 19 weeks

b) We can plug in 6 into w, since w represents the number of weeks Dale saves money. So,

A(w) = 700 - 18(6)

Multiply: A(w) = 700 - 108

Subtract: A(w) = $592

What is the solution to the matrix equation [2 1 1 0]x=5/10

Answers

[2 1 | 1 0 ] • x = [5 | 10]

What are the factor of 8x^3 - 27?..

Answers

Answer:

(x - 3)(4x² + 6x + 9)

Step-by-step explanation:

This is a difference of cubes which factors in general as

a³ - b³ = (a - b)(a² + ab + b²)

8x³ = (2x)³ ⇒ a = 2x

27 = 3³ ⇒ b = 3

Hence

8x³ - 27

= (2x)³ - 3³

= (2x - 3)( (2x)² + (2x × 3) + 3²)

= (2x - 3)(4x² + 6x + 9)

In a survey, 300 adults and children were asked whether they preferred hamburgers or pizza. The survey data are shown in the relative frequency table.

D. 40%

Step-by-step explanation:

You can fill in the table completely

[tex]\begin{array}{cccc}&\text{Hamburgers}&\text{Pizza}&\text{Total}\\\text{Adults}&0.24&0.36&0.6\\\text{Children}&0.11&0.29&0.4\\\text{Total}&0.35&0.65&1\end{array}[/tex]

From this table you can state that the probability that a randomly selected person is a child is 0.4 that is 40%.

Answer:

The percentage of the people surveyed are children is:

                               40%

Step-by-step explanation:

We are given a table as follows:

                            HAMBURGERS               PIZZA             TOTAL

ADULTS                   0.24                              0.36                0.6

CHILDREN                0.11                               0.29                 0.4

TOTAL                      0.35                              0.65                   1

Now we are asked to find the percent of students that were surveyed.

From the table we may see that the probability of children who were surveyed are:

     0.11+0.29=0.40

( since, the second column gives the total of the probability of children)

Hence, in percentage form it is given by:

0.40×100=40%

          Hence, the answer is:

               40%

The formula for finding the period of a tangent function is

x^2-y^2 = (x-y)(x+y) where x = 3a and y = 1

How far from the base of the house do you need to place a 15 foot ladder so that it exactly reaches the top of a 12 foot wall?

Answers

Answer:

9 ft

Step-by-step explanation:

The ladder is 15 foot

The height the ladder reaches from the bottom of the wall is 12 ft

The distance (x) from the bottom of the wall to the foot of the ladder is:

Applying the Pythagorean theorem;

x = [tex]\sqrt{15^2 - 12^2}[/tex] = 9 ft

A 15 foot ladder needs to be placed at a distance of 9 foot from the base of the house so that it exactly reaches the top of a 12 foot wall.

Further Explanation:Right triangle A right triangle is a triangle with one of its angles being 90 degrees or right angle.The triangle has two shorter sides making the right angle and the hypotenuse which is the longest side.Scalene triangleIt is a triangle that with sides and angles that are not equal.Pythagoras Rule According to Pythagoras rule, in a right angled triangle if the squares of the shorter sides are added then they are equivalent to the square of the hypotenuse.That is; [tex]a^{2} + b^{2} =c^{2}[/tex], where a and b are the shorter sides while c is the hypotenuse.

In this case;

The ladder, the wall of the house and the ground from the base of the house makes a right angled triangle;

Therefore;

Length of the ladder is the hypotenuse which is 15 ftThe wall of the house is one of the leg which is 12 ft

We are going to find the distance of the ladder from the base of the house on the ground which is the other leg.

Using Pythagoras theorem;

[tex]a^{2} + b^{2} = c^{2}[/tex]

Taking the horizontal distance of the ladder from the wall as b

Then;

[tex]b^{2} = c^{2} -a^{2}[/tex]

therefore,

[tex]b^{2} = 15^{2} -12^{2}[/tex]

[tex]b^{2} = 225 -144[/tex]

[tex]b^{2} = 81[/tex]

[tex]b = \sqrt{81} \\b= 9 ft[/tex]

Hence; the ladder needs to be placed at a distance of 9 foot from the base of the house.

HOW MANY ADDITIONAL STOPS FOR GAS WILL THEY NEED TO MAKE TO GET TO THEIR DESTINATION? explain your answer using numbers words and/or pictures

Answers

Answer:

2

Step-by-step explanation:

Given Data:

total distance= 850 miles

gas tank holds gas= 15 gallons

mileage = 72/3.2 miles/gallon

if

72 miles uses= 3.2 gallon

then

850 miles uses= x gallons

by cross-multiplication we get

72x=3.2(850)

x=37.778

i.e. 850 miles will use 37.7778 gallon of gas

Asgas tank holds 15 gallons

number of times gas tank is used up= 37.3/15

                                                            = 2.518

rounding off

number of times gas tank is used up=3

As they filled the gas tank at the start of the road trip, hence 3-1=2

ADDITIONAL STOPS FOR GAS WILL THEY NEED TO MAKE TO GET TO THEIR DESTINATION =2 !
