Richard walks every day for exercise at a rate of 1 kilometer every 12 min. At this rate ,how many meters can Richard walk in a hour? please helppppppp

Answers

Answer 1

Answer:

Answer: He can walk 5000 meters in one hour.

Step-by-step explanation:

According to the question,

$\text{ The distance he covered in 12 minutes }=\text{ 1 km}$

$\text{ The distance he covered in 60 minutes }=\text{ 5 km}$

$\text{ The distance he covered in 1 hour }=\text{ 5 km}$

Now, 1 km = 1000 meters,

$\implies \text{ The distance he covered in 1 hour }=\text{ 5000 m}$

Answer 2

Answer: 60 minutes in an hour
60÷12=5
1,000 meter in 1 km
5×1=5
5×1000=5000
therefore, 5000 meters

Answers

you have the area of the squares
100 in^2
area of a square = l*w
so length and width of the square both equal 10in
there are 4 squares going across the semi circle so...
diameter of semicircle is 10+10+10+10 =40in and radius is 20in
to find area of semicircle the formula is 1/2 pi r^2
so plug in the numbers 1/2(3.14) (20)^2 = 628 in ^2
now add that to area of big square part of window
40 inches length * 40 inches width = 1600in^2 (or you can just add them all up )
add up the areas now 1600+628= 2228 in^2
i think that is right

a) We know that the radius of the top of the window is two side lengths of a square. Since each square has a side length of 10 inches, the radius of the half-circle portion is 20 inches. The area of a half-circle is (pi*r²)/2 (r being radius and pi being 3.14). There are 16 squares as well. So the equation is ((3.14*20²)/2) + (16*100)=2,228 in²
b) The next part's a little tricky, but just add 4 inches to the radius and 4 inches to all of the affected outer-rim squares. You should get 3016.32 in²

In mathematics, a rational number is any number that can be expressed as the quotient or fraction p/q of two integers, a numerator p and a non-zero denominator q. Since q may be equal to 1, every integer is a rational number.

Answer: D

Im positive it is D and it might be 2.3333333333. But, i will stick with D.

The second of 2 numbers is 5 more than twice the first. Their sum is 29. Find the numbers

Answers

Call the numbers x and y. Let y be the larger number.
The second of 2 numbers is 5 more than twice the first is y = 2x+5
Their sum is 29 is x+y=29.
Substitute 2x+5 for y in the second equation.x+2x+5=29
3x=24
x=8
y = 2(8) + 5 = 21
Hope the solution helped.
Briemode!:)

so call the numbers x and z
first number=x
second number=z
second of 2 numbers (z) is = 5 more than (5+) twice the first (2x)
z=5+2x
their sum is 29
x+z=29
subsisute 5+2x for z in equation
x+5+2x=29
3x+5=29
subtract 5
3x=24
divide bboth sides by 3
x=8
subsitute 8 for x
z=5+2(8)
z=5+16
z=21

numbers are 8 and 21

Question 2 of 7A hospital has a large fish tank with the dimensions shown. The tank does NOT have a cover. What is the surface area of the fish tank?

Answers

Answer:

332 ft²

Step-by-step explanation:

The total area of the fish tank is the sum of the areas of the base and the walls.

The area of a rectangle is A = side 1 × side 2

Base

A = 12 ft × 5 ft = 60 ft²

2 8×12-walls

A = 8 ft × 12 ft = 96 ft²

2 walls: 2 × 96 ft² = 192 ft²

2 5×8-walls

A = 5 ft × 8 ft = 40 ft²

2 walls: 2 × 40 ft² = 80 ft²

Total area: 60 ft² + 192 ft² + 80 ft² = 332 ft²

2 times 8 x 12

192

2 times 5 x 8

80

2 times 12 x 5

60

192+80+60=332 ft^2
