Answer:

25%

Step-by-step explanation:

We know that there are ten purple popsicles. Together without the purple popsicles, there are 40 popsicles in total. Therefore there is a 10/40 chance to get purple. We need to turn this into a percentage so we do (10 / 40) x 100. This would equal to 25%, therefore, there is a 25% probability to get a purple popsicle.

Arc Length Formula [Parametric]: $\displaystyle AL = \int\limits^b_a {\sqrt{[x'(t)]^2 + [y(t)]^2}} \, dx$

Step-by-step explanation:

Step 1: Define

Identify

$\displaystyle \left \{ {{x = t - cos(t)} \atop {y = 1 - sin(t)}} \right.$

Interval [0, π]

Step 2: Find Arc Length

[Parametrics] Differentiate [Basic Power Rule, Trig Differentiation]: $\displaystyle \left \{ {{x' = 1 + sin(t)} \atop {y' = -cos(t)}} \right.$
Substitute in variables [Arc Length Formula - Parametric]: $\displaystyle AL = \int\limits^{\pi}_0 {\sqrt{[1 + sin(t)]^2 + [-cos(t)]^2}} \, dx$
[Integrand] Simplify: $\displaystyle AL = \int\limits^{\pi}_0 {\sqrt{2[sin(x) + 1]} \, dx$
[Integral] Evaluate: $\displaystyle AL = \int\limits^{\pi}_0 {\sqrt{2[sin(x) + 1]} \, dx = 4\sqrt{2}$

A tennis racket normally costs $80. The tennis racket is on sale for 30% off. What is the sale price of the tennis racket

velikii [3]

The answer would be $56
The reason is you would do 80*.3(30% in decimal form) which would equal 24
24 is what is being taken off of the normal cost.
So you would then do 80-24 which would equal $56.

Jennifer earns $39 for 6 hours of babysitting.how much will she earn for 10 hours

nadya68 [22]

Find the unit rate.

39/6 = 6.5

$6.50 an hour

multiply this by ten to find the cost for 10 hours

$6.5 x 10 = $65

she will earn $65 in ten hours.
hope this helps! :D

Rewrite the expression with rational exponents as a radical expression by extending the properties of integer exponents. two to

Lubov Fominskaja [6]

Answer:

The answer is " $\sqrt[8]{2^5}$ ".

Step-by-step explanation:

Given value:

$\to \frac{2 \frac{7}{8}}{2 \frac{1}{4}}$

They understand that, by using algebraic expressions laws, they subtract that inverse whenever we subtract powers with the same base. Every exponent's core is 2, therefore we subtract:

$\to \frac{7}{8} - \frac{1}{4}$
