dress for $20, coupon for 40% off. After using the coupon, what is the sale price of the dress?

Answer:

∠B = 36.87

Step-by-step explanation:

Since you are trying to find the angle measurement, you must use the inverse of cosine: [tex]cos^{-1}[/tex] (you're using cosine because you have the opposite side and adjacent side):

[tex]cos^-1(4/5)[/tex]

≈36.87

Step-by-step explanation:

Negative four

-4

Equal to x

-4=x

Divided by five

-4=x/5

Plus six

-4=x/5 +6

Interpretation in the picture above

Solution

Multiply through with 5

5×-4=5×x/5 + 5×6 as shown in the second picture

-20=x+30

Collect like terms

-20-30=x

-50=x or x=-50

Answer:

If I wanted to safely climb a 50 foot wall, I would use a 51 foot ladder.

Step-by-step explanation:

If I wanted to climb a fifty foot (50 ft) wall, I would use a fifty one foot (51 ft) ladder because the safe way to position a ladder against the wall requires that I leave one foot (1 ft) distance from the base of the ladder to the wall. That way, the ladder won't be too close nor too far from the wall.

Answer:

There is not enough information to compare the volume of the prisms.

Step-by-step explanation:

To find the volume of rectangular prisms, the length , width and height must be given. The volume of rectangular prisms is gotten by multiplying the three dimension: length, width and height which is expressed in cubic units. To compare the two volumes, the three dimensions must be given.

Hence, there is not enough information to compare.

Step-by-step explanation:

y = 10x - 32

To find the x intercept set y =0 and solve for x

0 = 10x -32

Add 32 to each side

32 = 10x

Divide by 10

32/10=10x/10

3.2 = x

To find the y intercept set x =0 and solve for t

y = 10*0 -32

y= -32

Answer:

y.(0,-32)

x.(3.2,0)

Answer:

x=((log(81))/(log(3))+2)/3

Step-by-step explanation:

so what you want to do is get 3x-2 out of the exponent

you can do that by using log

so apply log to both sides and you get

log(81)=(3x-2)log(3)

the 3x-2 is moved in front of the log due to a log rule

then (log(81))/(log(3))=3x-2

(log(81))/(log(3))+2=3x

((log(81))/(log(3))+2)/3=x

then use a calculator to find the exact value

Answer:

6 ways

Step-by-step explanation:

The total number of people we have entering Kennywood is 6, since it’s Jim with 5 of his friends.

Now, we can only have movement through the game one at a time

The number of ways they can move through the gate one at a time is 6C1 ways

and that is mathematically;

if we are to select a number of r items from a total of n, the number of combinations or ways is;

nCr = n!/(n-r)!r!

Applying these to the problem at hand, we have

6!/(6-1)!1! = 6!/(5!)(1!) = (6 * 5!)/5! = 6 ways

Answer:

1/6

Step-by-step explanation:

Part A. Yes, these ratios forms a proportion

Part B-  the ratio of the number of friends in Case 1 to the number of friends in Case 2 is 5:1

It is described as the comparison of two quantities to determine how many times one obtains the other. The proportion can be expressed as a fraction or as a sign: between two integers.

The ratios in cases 1 and 2 form a proportion. IT can be seen by dividing case a by 5 which gives 4:3;

i.e 20:15

If we divide both numerator and denominator by 5, then we have 4/3.

This shows case 1 and 2 have the same proportions of friends to strangers.

Part B; The number of friends in case 1 is 20 while in case 2 is 4.

we have, 20:4

= 20  4

Dividing each by 4, we have 5:1.

Which means that the ratio of friends that in case 1 to case 2 is 5:1.

Answer:

5

Step-by-step explanation:

you could use a calculator, but it works like this too i guess. :P also you could just try and guess, "what squared (multiplied by itself) is 25" good luck

Answer:

5 should be the answer for the square root

Answer:

In 6 years form now, the balance in Gordon's account will be = {$1,200 x [1 + (2.5% x 6 years)]} = $1,380

his account will have earned = 2.5% x 6 years x $1,200 = $180 in interests over the six years

In 6 years form now, the balance in Bailey's account will be = $900 x (1 + 3.25%)⁶ = $1,090.39

his account will have earned = $190.39 in interests over the six years

Bailey's account earned more interest than Gordon's, even though his initial balance was much lower. This was due to higher interest rates and more important, because Bailey earned compound interest.

Answer:

see explanation

Step-by-step explanation:

Using Pythagoras' identity on the right triangle.

The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is

AC² = AB² + BC² , substitute values

AC² = 9² + 12² = 81 + 144 = 225 ( take the square root of both sides )

AC = [tex]\sqrt{225}[/tex] = 15 cm

-------------------------------------------

The area of Δ ABC is calculated as

A = [tex]\frac{1}{2}[/tex] × BC × AB = [tex]\frac{1}{2}[/tex] × 12 × 9 = 6 × 9 = 54 cm²

Answer:

(x-9)(x-3)

Step-by-step explanation:

Look to the number on the right, 27, and list out the factors. (1 and 27, 3 and 9, -1 and -27, -3 and -9)

Next, find the factors that would equal the middle number, -12, when added. -3 and -9 add to -12. Therefore, choose these numbers and put them in the form (x-9)(x-3).

By Probability, 0.25 is simulation could you use to answer questions about whether a surfer will see a dolphin.

What does a probability simple definition entail?

A probability is a number that expresses the possibility or likelihood that a specific event will take place. Probabilities can be stated as proportions with a range of 0 to 1, or as percentages with a range of 0% to 100%. Probability is a measure of how likely or likely-possible something is to happen.

                                         For instance, the chance of flipping a coin and obtaining heads is 1 in 2, as there is only one method to acquire a head and there are a total of 2 potential outcomes (a head or tail). P(heads) = 12 is the formula.

the beach lifeguards, there is a 25% chance.

                25%  = 1/4 = 0.25

5sin(3pix)+8=4

5sin(3pix) = -4

sin(3pi x) = -0.8

Basic angle: sin^-1(0.8) = 0.927295218

[tex]DR=PT=3cm[/tex] and [tex]RP=4cm[/tex]

Points D, R, P and T are collinear.

The image attached shows a representation of this problem.

By sum of segments, we have

[tex]DT=DR+RP+PT[/tex]

Replacing all given values, we have

[tex]DT=3+4+3=10 \ cm[/tex]

Therefore, the segment DT is 10 centimeters long.

Now, we know that point E is the center of segment RP, which means is a middle point, divides the segment equally. So, to prove that segment DT is symmetrical regarding point E, we need to prove that both sides are equal.

[tex]RE=EP=2cm[/tex], by definition of middle point.

By sum of segments, we have

[tex]DR+RE=3+2=5cm\\EP+PT=5cm[/tex]

Which means [tex]DR+RE=\frac{DT}{2}\\ EP+PT=\frac{DT}{2}[/tex].

Therefore, segment DT is symmetrical regarding point E.
