The spinner would land on the yellow about 100 times looking at the graph.

Nastasia [14]4 years ago

4 0

Answer:

100 times

Step-by-step explanation:

Because there is only one yellow and 400 divided by 4 is 100. But if it was blue it would be 200 because to of the triangles are blue

What is the area of a sector that has a radius of 25 mm and has an angle measure of 50

attashe74 [19]

Answer : The area of sector is, $272.57mm^2$

Step-by-step explanation :

Formula used to calculate the area of sector in degree is:

Area of sector = $\frac{\theta}{360}\pi r^2$

where,

$\theta$ = angle = $50^o$

r = radius = 25 mm

Now put all the given values in the above formula, we get:

Area of sector = $\frac{\theta}{360}\pi r^2$

Area of sector = $\frac{50}{360}\times 3.14\times (25)^2$

Area of sector = $272.57mm^2$

Therefore, the area of sector is, $272.57mm^2$

A store sells candy at $.50, $1, $1.50, $2, and $3 per kilogram. you can see that the unit price of candies that $3 buy very inv

olga nikolaevna [1]

Answer:

constant of variation = 3

Step-by-step explanation:

Given that a store is selling different candies costing $.50, $1, $1.50, $2, and $3 per kilogram.

As given

Amount available to buy candies = $ 3

Suppose

Unit price of candies = x

Number of candies bough = y

Constant of variation = k

As we know the unit price of candies and number of candies bought vary inversely. As the unit price would increase the the number of candies bought in available amount ($3) would decrease.

So our formula to calculate formula for constant of variation would be as shown below:

k= xy →(1

Case 1

if we take unit price x to be $0.5, then we can buy 6 kg of candies in $ 3. In this case constant of variation can be found from above equation (1) as follows:

k = (0.5)(6) = 3

Case 2

if we take unit price x to be $1, then we can buy 3 kg of candies in $ 3. In this case constant of variation can be found from above equation (1) as follows:

k = (1)(3) = 3

Case 3

if we take unit price x to be $1.5, then we can buy 2 kg of candies in $ 3. In this case constant of variation can be found from above equation (1) as follows:

k = (1.5)(2) = 3

Case 4

if we take unit price x to be $2, then we can buy 1.5 kg of candies in $ 3. In this case constant of variation can be found from above equation (1) as follows:

k = (2)(1.5) = 3

Case 4

if we take unit price x to be $3, then we can buy 1 kg of candies in $ 3. In this case constant of variation can be found from above equation (1) as follows:

k = (3)(1) = 3

So, our constant of variation is 3.

Which is a stretch of an exponential decay function ?

sergiy2304 [10]

Using translation concepts, a stretch of a decay exponential function is given by:

$f(x) = 5\left(\frac{1}{5}\right)^x$

<h3>What is a translation?</h3>

A translation is represented by a change in the function graph, according to operations such as multiplication or sum/subtraction in it's definition.

An exponential decay function is given by:

$y = ab^x$

In which |b| < 1.

A stretch means that the function is <u>multiplied by a factor with absolute value greater than 1</u>, hence the function would be given by:

$f(x) = 5\left(\frac{1}{5}\right)^x$
