A sprinter ran the 400 meter dash in 44.62 seconds. Convert her speed into miles per hour
Answer:
v = 20.7 mph
Step-by-step explanation:
Given that,
Distance, d = 400 m
Time, t = 44.62 s =
We need to find the speed of the sprinter. The speed of an object is defined as total distance covered divided by time taken. It can be given by :
[tex]v=\dfrac{d}{t}\\\\=\dfrac{0.248\ mile}{0.012\ s}\ (As\ 1\ m=0.000621371\ mile)\\\\=20.7\ mph[/tex]
Hence, the speed of the sprinter is equal to 20.7 mph.

Given a = 20, c=52, find b =
Answer:
b = 48
Step-by-step explanation:
a = 20
b = ?
c = 52
a^2 + b^2 = c^2
20^2 + b^2 = 52^2
400 + b^2 = 2704
b^2 = 2704 - 400
b^2 = 2304
sqrt(b^2) = sqrt(2304)
b = sqrt(2304)
b = 48

500 ml water 4 times a day = 500x4= 2000 ml water per day
there are 7 days in a week so,
2000 x 7 = 14000 ml
1000mililitre = 1 litre
14000ml = 14 L per week

A jockey will ride horses in 10 different races at a race track today. The number of races that the jockey will win is what type of random variable
Answer:
X is a discrete Random variable where X is the number of races Jockey can win.
Step-by-step explanation:
To find - A jockey will ride horses in 10 different races at a race track today.
The number of races that the jockey will win is what type of random variable ?
Proof -
Given that,
A jockey will ride horses in 10 different races at a race track today.
Let us assume that,
X is the number of races Jockey can win
So,
X can take value 0, 1, 2, 3, ......10
As,
It can take countable finite values
So,
X is a discrete Random variable
∴ we get
X is a discrete Random variable where X is the number of races Jockey can win.

The highest speed ever recorded for a bicycle was 166.944 miles per hour. What is this speed rounded to the NEAREST tenth?
Answer:
166.9 miles per hour
Step-by-step explanation:
To round a number to the nearest tenth, look at the next place value to the right (the hundredths). If it's 4 or less, just remove all the digits to the right. If it's 5 or greater, add 1 to the digit in the tenths place, and then remove all the digits to the right. Then, the answer is 166.9.
PLEASE HELP LOOK AT PICTURE YOU ANSWER I GIVE BRAINLIEST
Answer:
Your answer would be 26.64cm.
A step-by-step explanation for you, peabrain:
For all four sides:
1.8cm x 2.7cm = 4.86cm
4.8cm x 4 sides = 19.44cm
For the top and bottom:
1.8cm x 1.8cm = 3.6
3.6cm x 2 sides = 7.2cm
For the complete LSA (lateral surface area):
19.44 + 7.2cm = 26.64cm
Do not forget to round, if that is in your homework instructions :-)!
Answer:
Solution given;
l=1.8cm
b=1.8cm
h=2.7cm
now
lateral surface area =2(lb+lh+bh )
=2( 1.8*1.8+1.8*2.7+1.8*2.7)
=25.92cm² is a required answer.

The circumference of the hub cap of a tire is 75.74 centimeters. Find the area of this hub cap. Use 3.14 for PI. Use pencil and paper. If the circumference of the hub cap were smaller, explain how this would change the area of the hub cap.
Answer:
hcbhvhchgcvgfbvvhhs
Step-by-step explanation:
cbhchchfvhvhshc;h
Answer:
456.73 cm²
Step-by-step explanation:
Area of a circle = πr²
The radius of the hub cap
= 75.74÷3.14÷2
= 12.06 cm (rounded to the nearest hundredth)
The area of the hub cap
= 3.14 × 12.06²
= 456.7314968152...
= 456.73 cm² (rounded to the nearest hundredth)
Circumference means the perimeter of a circle. So if the perimeter of a shape is smaller, it makes the shape turn out to be smaller.
So the area of the hub cap will be smaller.
[tex]x {}^{2} \div a + y {}^{2} \div b = 1[/tex]
find x
Answer:
[tex]x=\sqrt{\dfrac{a(b-y^2)}{b}}[/tex]
Step-by-step explanation:
The given equation is :
[tex]x^2\div a+y^2\div b=1[/tex]
We need to find the value of x.
It can also written as :
[tex]\dfrac{x^2}{a}+\dfrac{y^2}{b}=1[/tex]
Subtract [tex]\dfrac{y^2}{b}[/tex] from both sides,
[tex]\dfrac{x^2}{a}+\dfrac{y^2}{b}-\dfrac{y^2}{b}=1-\dfrac{y^2}{b}\\\\\dfrac{x^2}{a}=\dfrac{b-y^2}{b}\\\\\text{Cross multiplying both sides}\\\\x^2=\dfrac{a(b-y^2)}{b}\\\\x=\sqrt{\dfrac{a(b-y^2)}{b}}[/tex]
Hence, the value of x is equal to [tex]\sqrt{\dfrac{a(b-y^2)}{b}}[/tex].

Answer:
<1= 62
•it is 62 because it is an alternate interior angle which is congruent
<2= 83
• when you add the given angles 62 and 35 you get 97 and a triangle is 180 so you subtract 97 from 180
<3=35
• it is 35 because it is an alternate interior angle which is congruent
Step-by-step explanation:
62+35= 97
180-97= 83

A local department store sells carpet in 4 sizes. Each carpet comes in 3 different qualities. One of the sizes comes in 5 colors. The other sizes come in 2 colors. How many choices of carpet are there
Answer:
23.
Step-by-step explanation:
You would multiply the 4 sizes of carpet by the 3 qualities, which equals 12. Then, you add 5+2+2+2. So it would end up being 12+11.
Do the sides 4, 5, and 6 form a Pythagorean Triple?
Answer:
They do not form a Pythagorean Triple.
If it was a Triple, 4^2+5^2 should equal 6^2.
4^2+5^2=16+25=41
6^2=36
41≠26
It doesn't work, therefore it is not a Pythagorean Triple.
Answer:
no
Step-by-step explanation:
