Hi anyone help me with this it’s for my daughter and i am not good with mathematics

Answer:

You will pay $18.69 for a item

Step-by-step explanation:

if you buy an item at $74.75 with 75% discount, you will pay 74.75 - 56.0625 = 18.69 dollars.

Answer:

$299

Step-by-step explanation:

The discount is 75%, so the sale price represents 25% of the original price.

25% : $74.75

(multiply both sides by 4 to get 100%)

100% : $299

Answer:

y=2√3, or 3.46410161513

Step-by-step explanation:

The smaller triangle is a right isosceles triangle, so the other side is also √2. To figure out it’s hypotenuse, you can use the Pythagorean theorem.

√2²+√2²=c²

2+2=c²

4=c²

√4=c

c=2

Now that we know that value, we can look at the bigger triangle.  It is a 30-60-90 triangle, which has special properties.

Y would equal the two of the base times the square root of three.

y=2√3, or 3.46410161513

The value of the y is 2√3 if the value of hypotenuse in the triangle with 60-degree angles is 2

It is a triangle in which one of the angles is 90 degrees and the other two are sharp angles. The sides of a right-angled triangle are known as the hypotenuse, perpendicular, and base.

From the sin ratio in the triangle with angle 45 degree

Sin45 = √2/x

x = 2

From the triangle with angle 60 degree

y/2 = tan60

y = 2√3

Thus, the value of the y is 2√3 if the value of hypotenuse in the triangle with 60-degree angles is 2

Answer: About 10 ft.

Use Pythagorean's Theorem!

c=[tex]\sqrt{9^2+3^2}[/tex]

9 * 9 = 81

3 * 3 = 9

81 + 9 = 90

[tex]\sqrt{90\\}[/tex] = 3[tex]\sqrt{10}[/tex] ≈ 10 ft.

Answer:

35

Step-by-step explanation:

The first number that appears in both sequences is 35.

Subtraction in mathematics means that is taking something away from a group or number of objects. When you subtract, what is left in the group becomes less.

Now, The first sequence starts with 20 and adds 5 each time, so the first few terms are:

20, 25, 30, 35, 40, 45, 50, 55, 60, ...

And, The second sequence starts with 56 and subtracts 7 each time, so the first few terms are:

56, 49, 42, 35, 28, 21, 14, 7, 0, ...

Hence, Looking at these lists, we can see that the first number that appears in both sequences is 35.

This is the fifth term in the first sequence as,

⇒ 20 + 5 + 5 + 5 + 5 = 35

And, the fourth term in the second sequence is,

⇒ 56 - 7 - 7 - 7 - 7 = 35

Hence, the first number that appears in both sequences is 35.

Answer:

Total distance of entire trip in miles = 360 miles

Step-by-step explanation:

Given:

Percent trip completing = 60%

Total distance cover in 60% trip = 216 miles

Find:

Total distance of entire trip in miles

Computation:

Total distance of entire trip in miles = Total distance cover in 60% trip[100%/Percent trip completing]

Total distance of entire trip in miles = 216[100%/60%]

Total distance of entire trip in miles = 21,600/60

Total distance of entire trip in miles = 360 miles

Answer:

5/6

Step-by-step explanation:

Answer:

[tex](a)\ d'(x) = x + 32[/tex] i.e. The inverse function

[tex](b)\ d'(10) = 42[/tex] i.e. The French size of a dress if it is U.S. size 10 is 42.

Step-by-step explanation:

Given

[tex]d(x) = x - 32[/tex]

Solving (a): The inverse function

[tex]d(x) = x - 32[/tex]

Replace d(x) with y

[tex]y = x - 32[/tex]

Swap y and x

[tex]x = y - 32[/tex]

Make y the subject

[tex]y = x + 32[/tex]

Replace y with d'(x)

[tex]d'(x) = x + 32[/tex]

Hence, the inverse function is: [tex]d'(x) = x + 32[/tex]

Solving (b): US size of 10

[tex]d'(x) = x + 32[/tex]

Substitute [tex]x =10[/tex]

[tex]d'(10) = 10 + 32[/tex]

[tex]d'(10) = 42[/tex]

Answer:

72 or 75

Step-by-step explanation:

If we are going in order then the median would be 72.

If we are going by what you posted, then it would be 75.

You were asking about the mean, so I though I would just add it in here.

So basically, the mean is just where you add up all the numbers, and then divide them by how many numbers you have.

For your problem, this is 39+87+72+88+75+87+15+53+53. This equals 569.

Now, lets count how many numbers we added: 1...2...3...4...5...6...7...8...9.

Ok, so lets divide the 569 by 9. This should get you 63.222...

That is your mean.
