Answer: Micheal's average Speed =6.885 miles per hour
Step-by-step explanation:
Speed= Distance /time
Given the distance he ran as = 5 1/4 miles
And Time taken = 45 3/4 minutes
changing to hours becomes
60 mins = 1 hour
45 3/ 4 mins = 45 3/4 mins/ 60mins x 1hour
= 45.75 /60 = 0.7625hours
Therefore Micheal's average Speed= Distance /time
=5 1/4miles / 0.7625hours = 5.25/ 0.7625
=6.885 miles per hour
approximately 7 miles/hour.

What is the perimeter of a square if the length of one of the diagonals is 12 cm?
6v2 cm
2412 cm
48 cm
24 cm
Answer:
Step-by-step explanation:
Use Pythagorean theorem to find the length of the square.
Length of the square = a
a² +a² = diagonal²
2a² = 12²
2a² = 144
a² = 144 ÷ 2
a² = 72
[tex]a =\sqrt{72}\\\\ = \sqrt{2*2*2*3*3}\\\\ = 2*3\sqrt{2}\\\\a = 6\sqrt{2}\\\\\\\\Perimeter= 4a\\\\ = 4*6\sqrt{2}\\\\= 24\sqrt{2} cm[/tex]
A concert venue has 20 seats in the first row and an 5 additional seats in each successive row. If there are 35 rows of seats then how many people can attend a sold-out show? 3,675 190 2,100
Answer:
3,675 people
Step-by-step explanation:
First row, a = 20
Common difference, d = 5
number of terms, n = 35
Sn = n/2 {2a + (n - 1)d}
= 35/2 {2*20 + (35 - 1)5}
= 35/2 {40 + ( 34)5}
= 17.5(40 + 170)
= 17.5(210)
= 3,675 people
The answer is actually 3675.

Let g(x) be the reflection across the x-axis of the function f(x) = 7x + 3. Identify the rule for g(x).
Answer:
(x,y) => (x, -y)
Step-by-step explanation:
[tex]y = 7x + 3[/tex]
[tex] - y = 7x + 3[/tex]
[tex]y = - 7x - 3[/tex]
so
[tex]g(x) = - 7x - 3[/tex]
Hence, [tex]g(x) = - 7x - 3[/tex].
What is the function?
Functions are often defined by a formula that describes a combination of arithmetic operations and previously defined functions; such a formula allows computing the value of the function from the value of any element of the domain.
Here given that,
Let [tex]g(x)[/tex] be the reflection across the x-axis of the function [tex]f(x) = 7x + 3[/tex]. Identify the rule for [tex]g(x)[/tex].
So,
[tex]y = 7x + 3\\-y= 7x + 3\\y = - 7x - 3\\g(x)=- 7x - 3[/tex]
Hence, [tex]g(x) = - 7x - 3[/tex].

1/4
off adult price
40% off child price
Work out the total price David pays after using his discount card
Answer:
£101
Step-by-step explanation:
60 divided by 4 = 15
15 x 3 = 45
£45 = adult price
10% of £45 = £4.50
40% of £45 = £18
£45 - £18 = £27
£27 = 1 child ticket
£27 x 2 = £56
£56 = two child tickets
£56 + £45 = £101

if x + 1/x = 5, find the value of x^3 + 1/x^3
Answer:
x=5/3 your answer right answer
Answer:
110
Step-by-step explanation:
The expansion (a + b)³ is
(a + b)³ = a³ + b³ + 3ab(a + b)
Then
(x + [tex]\frac{1}{x}[/tex] )³ with a = x and b = [tex]\frac{1}{x}[/tex]
= x³ + [tex]\frac{1}{x^3}[/tex] + 3x . [tex]\frac{1}{x}[/tex] (x + [tex]\frac{1}{x}[/tex] )
Thus
x³ + [tex]\frac{1}{x^3}[/tex] = (x + [tex]\frac{1}{x}[/tex] )³ - 3(x + [tex]\frac{1}{x}[/tex] )
= 5³ - 3(5)

Step-by-step explanation:
Ethan has $620 to spend at a bicycle store for some new gear and biking outfits. Assume all prices listed include tax. He buys a new bicycle for $427.57. He buys 4 bicycle reflectors for $11.38 each and a pair of bike gloves for $31.41. He plans to spend some or all of the money he has left to buy new biking outfits for $57.75 each. Write and solve an inequality which can be used to determine oo, the number of outfits Ethan can purchase while staying within his budget.
Answer: 620≥ 427.57+ 11.38(4)+ (31.41) +57.75x
Step-by-step explanation:
So our limit is the 620$ that he has to spend. We know for a fact that the bike costs about 427.57 dollars. 4 $11.38 reflectors are purchased as well as gloves for 31.41. Now however many outfits he can purchase cannot exceed or go over his money limit of 620 so the variable (x) represents how many outfits he can buy without going over.
We are required to write an inequality for the problem and also solve it
The number of biking outfit Ethan can purchase is 2
Given:
Total amount Ethan has = $620
Amount of bicycle = $427.57
Bicycle reflector = $11.38
Cost of 4 Bicycle reflector = $11.38 × 4
= $45.52
Cost of bike glove = $31.41
Cost of biking outfit = $57.75
Write an inequality to solve for the number of biking outfit Ethan can purchase
let
x = number of biking outfit Ethan can purchase
620 ≥ 427.57 + 45.52 + 31.41 + 57.75x
620 ≥ 504.5 + 57.75x
620 - 504.5 ≥ 57.75x
115.5 ≥ 57.75x
x ≥ 115.5 / 57.75
x ≥ 2

What is perimeter of the semi circle?
Answer:
54.22 mm
Step-by-step explanation:
Find the circumference of the circle and then divide it by 2.
We start with the formula for the circumference for the circle:
C = 2πr
To find r, divide 22 by 2:
22/2=11
Now find the cicumference:
C = 2πr = 2(3.14)(11) = 108.46 mm
NOW, to find the perimeter of the semicircle, divide the circumference by 2:
108.46/2 = 54.22 mm
