a soccer field is a rectangle 90 meters wide and 120 meters long. coach asks players to run from one corner to the corner diagonally across. what is this distance?
Answer:
Step-by-step explanation:
if we have a rectangle with W=90 and L=120, and we need to find the diagonal
we will have a right triangle with the legs 90,120
diagonal is the hypothenuse
c^2=90^2+120^2=8100+14400=22500
c=sqrt22500=150
the diagonal, c=150

Answer:
A: [tex]\frac{1}{2\sqrt{x-1} }[/tex]
B:[tex]\frac{1}{4\sqrt[4]{x^{3} } }[/tex]
c: 2x
Step-by-step explanation:
To find the derivative of x raised to the nth power we use the following template
[tex]x^{n}=nx^{n-1}[/tex]
Something else to keep in mind is that
[tex]\sqrt[n]{x^{y}}=x^{y/n}[/tex]
So knowing this we can rewrite a as follows
[tex]\sqrt{x-1} =(x-1)^{1/2}[/tex]
so we can use the template above and get
[tex]\frac{1}{2}(x-1)^{.5-1}[/tex]
So that simplifies to
[tex]\frac{1}{2}*(x-1)^{-\frac{1}{2}[/tex]
[tex]\frac{(x-1)^{-.5}}{2}[/tex]
[tex]\frac{1}{2\sqrt{x-1} }[/tex]
B: Same kind of deal here
[tex]\sqrt[4]{x}=x^{\frac{1}{4} }[/tex]
[tex]\frac{1}{4} *x^{\frac{1}{4}-1}[/tex]
[tex]\frac{x^{-\frac{3}{4}}}{4} =\frac{1}{4\sqrt[4]{x^{3} } }[/tex]
C: this one is by far the easiest because the derivative of a constant is 0 so we can just apply the same template from before and get

3. The diameter of a cylindrical column is 60cm and
its height is 4.2m
The cost of making it is £67.50 per cubic metre.
What is the cost of making it?
Answer:
£80.33
Step-by-step explanation:
The formula for the Volume of a cylinder = πr²h
The diameter of a cylindrical column is 60cm and its height is 4.2m
Converting the diameter to meter
100 cm = 1 m
60 cm = x
Cross Multiply
100 × x = 60 × 1
x = 60/100
x = 0.6m
The diameter of the cylinder = 0.6m
Radius = Diameter/2
Radius = 0.6m/2
Radius = 0.3m
Volume of a cylinder = πr²h
= π × 0.3² × 4.2
= 1.18752 m²
Approximately = 1.19 m²
The cost of making it is £67.50 per cubic metre. What is the cost of making it?
The volume of the cylindrical column = 1.19 m²
Hence:
1m² = £67.50
1.19m² = x
Cross Multiply
x × 1m² = 1.19 m² × £67.50
x = 1.19 m² × £67.50/1 m²
x = £ 80.325
Approximately = £80.33
Therefore, the cost of making the cylindrical column = £80.33

around the track?
Answer: 6 laps
Step-by-step explanation: 1/4 x 6 = 1 and 1/2
The number of laps Freddie walk around the track is, 4
What is division?Division is a mathematical operation, in which we distribute the number in equal parts, the number on the upper side is the total quantity and the number on the bottom side is equal parts of numbers which have to be distributed.
We denote division by '÷' this symbol.
Given that,
Freddie made the number line to model the laps he walks around a track at his school,
And each lap is 0.25 miles,
And Freddie walks a total of 1 mile,
So to find the number of laps he walks,
we can divide the total distance by the distance per lap:
Number of laps = 1/0.25 mile/miles per lap
= 4 laps
Hence, the number of laps is 4

Isaac makes china mugs with names painted on them. He charges a fixed fee for the mug, together with a fixed charge for each letter in the name. Penelope buys a mug for each of her children, Alexander and Lucia. She pays $12.60 for Alexander’s mug and $9.40 for Lucia’s mug. How much would Penelope have to pay for a mug with her own name on it?
Answer:
Not completely sure, and I know its late but for the other people that look at this, 11.80$
Step-by-step explanation:
I found how many more letters Alexander had over Lucia, then when I got 4 divided it in-between 12.60 - 9.40 (3.20) I got 0.8. knowing the letter cost i got the initial fee for the mug (5.40) and added 8x0.8 to it, resulting in my answer 11.80$
Penelope has to pay $11.8 for a mug with her own name on it.
Number of letters in Alexander's name = 9
Number of letters in Lucia's name =5
The Difference in the number of letters in both the names
= 9-5
=4 letters
Alexander pays = $12.60
Lucia pays = $9.40
Difference in payments = 12.60-9.40 = $3.20
It means charge for 4 letters = $3.20
So, charge for 1 letter = $0.80
Number of letters in Penelope's name = 8
So, Penelope will pay = 8*0.80 +fixed fee for the mug
= $6.4 +fixed fee for the mug
What will be the fixed fee for the mug?The Fixed fee for the mug will be the payment done by Penelope for either Alexander or Lucia minus the charge for each word in the word Alexander or Lucia respectively.
The Fixed fee for the mug = $9.40 - charge for each word in the word "Lucia"
The Fixed fee for the mug = 9.40 - 5*0.80 = $5.40
So, Penelope will pay = 6.4 +5.4 =$11.8
Therefore, Penelope has to pay $11.8 for a mug with her own name on it.

Louis wants to carpet the rectangular floor of his basement. The basement has an area of 2,000 square feet. The width of the basement is 4/5 its length. What is the length of Louis's basement?
Answer: 50 feet
Step-by-step explanation:
Let the length be represented by x
The width of the basement is 4/5 its length. Therefore, the width is 4/5x = 0.8x
Area = Length × Breadth
2000 = x × 0.8x
0.8x² = 2000
x² = 2000/0.8
x = ✓2500
x = 50
Therefore, the length is 50feet
A = 64 cm
ABC
A = 225 cm
In the diagram, how would you determine the length of the hypotenuse using the Pythagorean Theorem?
А
Find the area of the triangle then apply Pythagorean Theorem
B
Subtract the area of the squares and then apply Pythagorean Theorem
С
Add the areas of both squares together and then apply Pythagorean Theorem
D
Find the lenath of one side of each square and then apply the Pythagorean Theorem
Answer:
The hypotenuse formula is simply taking the Pythagorean theorem and solving for the hypotenuse, c.
Step-by-step explanation:
Solving for the hypotenuse, we simply take the square root of both sides of the equation a² + b² = c² and solve for c . When doing so, we get c = √(a² + b²)
The length of the hypotenuse is 17 cm and this can be determined by evaluating the length of one side of each square and then applying the Pythagorean Theorem.
Given :
Area of the small square is 64 [tex]\rm cm^2[/tex].Area of the larger square is 225 [tex]\rm cm^2[/tex].The side length of the smaller square can be calculated as:
[tex]a^2 = 64[/tex]
a = 8
The side length of the larger square can be calculated as:
[tex]b^2 = 225[/tex]
b = 15
So, the length of the perpendicular is 8 and the length of the base is 15. Now, apply the Pythagorean theorem in order to determine the length of the hypotenuse.
[tex]\rm H^2=P^2+B^2[/tex]
Now, substitute the values of known terms in the above expression.
[tex]\rm H^2=(8)^2+(15)^2[/tex]
[tex]\rm H = \sqrt{64+225}[/tex]
H = 17 cm
Therefore, the correct option is D) Find the length of one side of each square and then apply the Pythagorean Theorem.
