Question 19 makes no sense

Answers

Think:  To write the equation of a line in slope-intercept form y=mx+b, you must have the slope (m) and the y-intercept (b). 

g(0)= -6 tells us that the y-intercept is (0, -6).  Thus, b= -6.

(0,-6) and (15,-9) are points on the line.  Find the slope of the line.  It is:
          -9-(-6)
m = ------------- = -3/15 = -1/5
          15-0

Thus, the equation of the line in question is y=(-1/5)x - 6.

Important that you understand that g(0)=-6 is also represented by (0,-6), and that -6 is the y-intercept.

A regular room at the Great Wolf Lodge is $229.99. You have a discount code to get 20% off of the room rate. The sales tax on the hotel rooms is 13%. Find the total cost of the room.
Please explain how to do it. I don't understand how to do it.

Answers

229.99*.20 = $46 off
229.99-46 = $183.99
$183.99*.13 =$23.92 sales tax added
183.99+23.92 = $207.91
 


We'll start with our initial price- $229.99.

First, we'll want to apply our discount code, as you wouldn't want to discount something after taxes. To apply the discount, we will start by multiplying our percent by the original price.

Multiplying by a percent is easy! All we need to do is put the percent over 100, divide the fraction, and our decimal is the value.

[tex] \frac{20}{100}= \frac{1}{5} =0.2[/tex]

Now that we know our percent can be represented as "0.2," we will multiply 0.2 by our original price.

[tex]229.99*0.2= 45.998[/tex]

As our unit is money, we will round to the nearest hundredth. When we round to the nearest hundredth here, we can see that 20% of 229.99 is $46.00.

We aren't done calculating the discount yet, though! We still need to subtract the "46" from our original price, since we are only getting 20% off, not only paying 20%.

[tex]229.99-46.00=183.99[/tex]

Now that we have our discounted price, we need to add the sales tax to it. Again, we'll need to find our sales tax's value as a decimal.

[tex] \frac{13}{100} =0.13[/tex]

This time, we will multiply the discounted price by "1.13." The first "1" represents the discounted price, and the ".13" afterwards represents the cost of the sales tax.

[tex]183.99*1.13=207.9087[/tex]

Again, we'll need to round to the nearest hundredth, so our "207.9087" becomes "207.91."

With all of the logic above in mind, we can conclude that the cost of the room, after the discount and the sales tax, is $207.91.

Christopher just found beautiful yarn for 20% off at his favorite yarn store. He can make one scarf from 2/3 of a ball of yarn. If Christopher buys 12 balls of yarn, how many scarves can he make?

Answers

Answer:

16

Step-by-step explanation:

if 2/3 is used by one scarf, then we can divide 2/3 into 12

12/1 × 2/3

12/1 ×3/2= 36/2

36/2= 16

Christopher can create a total of 12 scarves with the 12 balls of yarn he buys, based on the ratio of 2/3 of a ball needed for one scarf.

Christopher can make scarves from yarn, where it takes 2/3 of a ball of yarn to make one scarf. If he buys 12 balls of yarn, we need to calculate the total number of scarves he can make.

Let's find out how many scarves he can create with 12 balls:

Firstly, determine how many scarf units are in one ball of yarn. Since it takes 2/3 of a ball to make a scarf, 1 ball equals 1.5 scarf units (since 1 / (2/3) = 1.5).Next, multiply the number of scarf units in one ball by the total number of balls. 1.5 scarf units per ball \\times 12 balls = 18 scarf units.Finally, since each scarf uses 2/3 of a ball, we divide the total number of scarf units by 1.5 to get the number of scarves. 18 scarf units / 1.5 = 12 scarves.

Therefore, Christopher can make 12 scarves with 12 balls of yarn.

audras parents are both in their forties. the sum of their ages is ninety -two. the product of their ages is 2,107. how old is audras oldest parent?

Answers

Audra's parents are 49 and 43 so the age of his/her oldest parent is 49.
49 + 43 = 92
49 x 43 = 2,107
:)

Answer: Hello there!

Let's define x = age of parent 1, and y = age of parent 2, and suppose that y is the oldest one.

we know that:

x + y = 92

x*y = 2107

now we have a system of equations that we need to solve:

the first step is isolate one of the variables in one of the equation, let's isolate x in the first equation:

x = 92 - y

now we can replace it in the second equation and find the value of y.

x*y = 2107

y*(92 - y) = 2107

92y - y^2 = 2107

now we need to solve a cuadratic equation!

-y^2 + 92y - 2107 = 0

using the Bhaskara formula, we get:

[tex]y = \frac{-92 +/- \sqrt{92^{2} -4 *(-1)*(-2107) } }{-2} = \frac{-92 +/- \sqrt{36} }{-2} = \frac{-92 +/- 6}{-2}[/tex]

so we have two solutions:

y = (-92 + 6)/(-3) = 43

y = (-92 - 6)/(-2) = 49

because y is the oldest one, we need to take the biggest solution, this is y = 49.

so the oldest parent has 49 years.

if you want to find the age of the other parent, replace this in the first equation:

y + x = 92

49 + x = 92

x = 92 - 49 = 43

find the length of the base indicated for each trapezoid

Answers

Final answer:

To find the base of a trapezoid, you can view the trapezoid as two right triangles joined together. The base of the trapezoid is the sum of the bases of these triangles. Depending on the orientations of the sides of the trapezoid and the height, you might need to use the Pythagorean theorem.

Explanation:

The question asks to find the length of the base for a given trapezoid. In order to do this, we can use concepts from geometry and trigonometry. Consider the trapezoid as two right triangles back to back. The base of the trapezoid is the sum of the bases of the two right triangles.

For example, if you have a trapezoid with sides A and B, and the height is H, you can use these sides and the trigonometric principles to calculate the lengths of the bases. If side A or B is not perpendicular to the base, you would need to use the Pythagorean theorem. That formula is A^2+B^2=C^2, where C is the hypotenuse of the right triangle formed.

In case, the sides A and B are perpendicular to the base, the lengths of the bases would simply be side A + side B. This would give you the total length of the base of the trapezoid.

What is 1 1/2 subtracted from the sum of 4 2/3 and 5 2/5

Answers

Hi there!

First, we need to add 4 2/3 and 5 2/5.

We should begin with converting the fractions into improper fractions.
4 2/3 + 5 2/5
= 14/3 + 27/5

Now, we find the common denominator.
= 70/15 + 71/15

We can add:
= 141/15

And simplify.
= 9 2/5

Finally, we subtract 1 1/2 from 9 2/5.
9 2/5 - 1 1/2
= 47/5 - 3/2
= 94/10 - 15/10
= 79/10
= 7 9/10

Your answer is 7 9/10.

Figure PQRS is rotated by 180 degrees about the origin in the counterclockwise direction to obtain figure P′Q′R′S′:
Which statement best compares the lengths of the sides of the two figures?

Length of PQ = Length of P′Q′
Length of PQ = Length of R′S′
Length of RS = Length of P′Q′
Length of RS = Length of Q′R′

Answers

i believe that the answer is length of PQ = length of P′Q′ since they are the same sides on both shapes

Answer:

A. Length of PQ = Length of P′Q′

Step-by-step explanation:

We are given,

Figure PQRS is rotated by 180° counter-clockwise about the origin to obtain P'Q'R'S'.

Since, we know that, 'Rotation' is a transformation that turns the figure around a fixed point to a certain degree.

We get that, rotation does not affect the length of the figure.

So, the length of PQ = length of P'Q' and length of RS = length of R'S'

Thus, according to the options, we get that option A i.e. Length of PQ = Length of P′Q′ is correct.

Answers

Answer:
y = 2x - 4

Explanation:
The general form of the slope-intercept equation is:
y = mx + c
where:
m is the slope
c is the y-intercept

We are given that the slope = 2
Therefore, the equation of the line becomes:
y = 2x + c

Now, we will need to get the value of c.
We are given that (7,10) belongs to the line. This means that this points satisfies the equation of the line. So, we will substitute with this point in the equation and solve for c as follows:
y = 2x + c
10 = 2(7) + c
10 = 14 + c
c = 10 - 14
c = -4

Based on the above, the equation of the line is:
y = 2x - 4

deena has a set of 4 coasters on her coffee table, and each coaster is shaped like a cylinder with a height of 0.5 inches and a radius of 2.5 inches. which is the total surface area of the 4 coasters?

Answers

It’s about 188.5 in squared

Final answer:

The total surface area for the 4 cylindrical coasters, each with a height of 0.5 inches and a radius of 2.5 inches, is approximately 188.4956 square inches.

Explanation:

Deena has a set of 4 coasters, each shaped like a cylinder.

To calculate the surface area of one coaster, we need to find the area of the two circular bases and the area of the side that wraps around the cylinder (the lateral surface area).

The formula for the surface area of a cylinder is SA = 2πr(h+R), where r is the radius, h is the height, and R is the radius of the bases.

Given a height of 0.5 inches and a radius of 2.5 inches:

SA = 2π(2.5)(0.5+2.5)

SA = 2π(2.5)(3)

SA = 2π(7.5)

SA = 15π

The result is the surface area for one coaster. As we have 4 coasters, we multiply this result by 4:

Total surface area for 4 coasters = 4 × 15π ≈ 4 × 47.1239 ≈ 188.4956 square inches.
