How many fractions are equalavent to 4/5

Answers

Equivalent fractions are multiples of a fraction that is completely reduced. And there is an infinite amount of numbers to multiply 4/5 by, so there is an infinite number of fractions equivalent to 4/5.

It's infinite. There are an infinite amount of numbers.

An arc on a circle measures 125°. The measure of the central angle, in radians, is within which range?

Answers

Answer:

$[0,2\pi]$

Step-by-step explanation:

Central angles are subtended by an arc between those two points.

The arc length is the central angle of a circle of radius one (measured in radians).

The central angle is also known as the arc's angular distance.

Here given that 125 degrees is the measure of an arc on a circle

The central angle will vary between 0 and 360 degrees

In radians this range can be specified as

$[0,2\pi]$

Answer:

π/2 to π radians

Cara has $25 to buy dry pet food and treats for the animal shelter. A pound of dog food cost $2 and treats are $1 apiece. If she buys 9 pounds of food, what is the greatest number of treats she can buy?

Answers

If dog food costs $2 a pound and Cara buys 9 pounds, her expenditure on dog food is 9 x 2. This makes $18. If she has a total budget of $25 and spends $18 on dog food, she has $7 left over for treats (25 - 18 = 7). At $1 each, she can buy up to 7 treats.

In sunlight, a vertical stick 6 ft tall casts a shadow 2 ft long. At the same time a nearby tree casts a shadow 14 ft long. How tall is the tree? Round to the nearest tenth A) 42.0 ft 
B) 85.7 ft 
C) 18.0 ft 
D) 52.5 ft<br /

Answers

The nearby tree's height is 42.0 ft, which is A

Alrighty friend, let me explain you a math.
We're gonna want to start by setting up a fraction. We'll set up the fraction as height/shadow. The stick's height is 6 feet and the shadow is 2 feet, making the fraction 6/2. The second fraction only gives us the shadow, so the fraction is x/14.
Now, we're gonna do some cross multiplication m8. 6/2 x x/14. Multiply 6x14= 84 and 2x(x)= 2x ---> 2x = 84
Do you some basic algebra here, and divide both sides by 2.
Your final answer is 42, so the tree is 42 feet tall.

Are the graphs of the lines in the pair parallel? Explain.Find the slope of a line parallel to 5x + 2y = 6

Answers

To make it easier turn this equation into a slope. To do that you must get "y" by itself on one side of the equal sign. The "y" have to be positive. Then plot it out. Enter the "x" (1 for example) in the equation and solve to get "y". Then use the ordered pair to plot out the slope. Then you find a coefficient of "x" that matches the one in this equation and plot that out. If it's parallel then it's right. :)
