A cyclist rides his bike at a speed of 27 miles per hour. What is this speed in feet per second? How many feet will the cyclist travel in 10 seconds? In your computations, use the fact that 1 mile is equal to 5280 feet. Do not round your answers. ​

I Forgot How To Do These Types Of Problems..A Cyclist Rides His Bike At A Speed Of 27 Miles Per Hour.

Answers

Answer 1
Favorite Answer
An hour is 60 min. times 60 seconds, or 3600 seconds.
A mile is 5280 feet so 27 miles is 27 * 5280 or 142,560 feet.
So we're saying he goes 142560 feet in 3600 seconds. Divide 142560/3600 and we get 39.6 feet per second.
In ten seconds he'll go 10 times that or 396.0 feet.

Juan has $67 in $5 and $1 bills. If has 19 bills in all, how many $1 bills does he have?

Answers

I think he has 7 one dollars

Juan have 7 bill for $1 bills.

What is an expression?

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

Juan has $67 in $5 and $1 bills.

And, He has 19 bills in all.

Now, Let number of $1 bills = x

And, Number of $5 bills = y

Here, Juan has $67 in $5 and $1 bills.

So, We get;

⇒ x + 5y = 67  .. (i)

And, He has 19 bills in all.

So, We get;

⇒ x + y = 19  

⇒ x = 19 - y .. (ii)

Substitute the value of x from (ii) in (i), we get;

⇒ x + 5y = 67

⇒ 19 - y + 5y = 67

⇒ 19 + 4y = 67

⇒ 4y = 67 - 19

⇒ 4y = 48

⇒ y = 12

And, from (ii),

⇒ x = 19 - y

⇒ x = 19 - 12

⇒ x = 7

Solve the system algebraically.
y = – 4x + 6

Answer:

We conclude that -1 = 0 is false, therefore the system of equations has no solution.

Step-by-step explanation:

Given the system of equations

y = – 4x + 6

y = – 4x + 5

solving the system of the equations

[tex]\begin{bmatrix}y=-4x+6\\ y=-4x+5\end{bmatrix}[/tex]

Substitute y = -4x+5

[tex]\begin{bmatrix}-4x+5=-4x+6\end{bmatrix}[/tex]

Refine – 4x + 5 = – 4x + 6

-1 = 0

FALSE!

Someone help me do this please. I included a picture.

Answers

Answer:

52° and 128°

Step-by-step explanation:

The sum of the angles in a triangle is 180°

So to find the angles, the easiest thing to do is to use that fact.

There is one angle missing in the triangle shown, so to find it you need to subtract (5x-2)° from 180° since the angle is located on a line.

Simplifying that, you get 180°-(5x-2)°.

Now you can use the fact at the top of these instructions.

So you get the equation: 180°=2x°+76°+180°-(5x-2)°

Solving this equation, you get x=26

Plug x into the values that have x in the picture, and you get 52° and 128°
