Answer:

1 7/20

Step-by-step explanation: 3/4+3/5 as a mixed number

Well you start by having 3/4+3/5 and then you multiply 5 times 3 which is 15, then you multiply 3 times 4 is 12. Now you multiply the denomerators which are 5 times 4 is 20 so what I did was I switch the number to on each side so the denomerators are 5 and 4 so I just put the 4 on the left side and then I put the 5 on the other side well you do numerator and the denomerator as the same number so you can multiply the numerator and the denomerator as the same on each side but so like this 5/5 * 3/4+3/5*4/4 now you multiply the numerator adn the denomerator anad you get 15/20+12/20 now you just add so 15+12 is 27 and you just leave the denomerator alone so it is 27/20 so now you have to divide. here is a trick up my sleeve you could do the football long division so you put it like 27/20. So now you have to figure out what can go into 27 with 20 which is 1 so you put that above the division sign and now you subtract 27 and 20 so that gives you 7 now you take that 7 and bring it above the 20 and not you have 7/20 and now you bring it up over and past the 1 and now you have 1 7/20 or you could say as like this one and seven 20 and can't 20th so I just put 20 so don't mind. I hope this is the answer!!

A wheel spins at 300 revolutions per minute. What is the angular velocity of the wheel, in radians per second? Round the answer

Ostrovityanka [42]

well, this is just a matter of simple unit conversion, so let's recall that one revolution on a circle is just one-go-around, radians wise that'll be 2π, and we also know that 1 minute has 60 seconds, let's use those values for our product.

$\cfrac{300~~\begin{matrix} r \\[-0.7em]\cline{1-1}\\[-5pt]\end{matrix}~~ }{~~\begin{matrix} min \\[-0.7em]\cline{1-1}\\[-5pt]\end{matrix}~~ }\cdot \cfrac{2\pi ~rad}{~~\begin{matrix} r \\[-0.7em]\cline{1-1}\\[-5pt]\end{matrix}~~ }\cdot \cfrac{~~\begin{matrix} min \\[-0.7em]\cline{1-1}\\[-5pt]\end{matrix}~~ }{60secs}\implies \cfrac{(300)(2\pi )rad}{60secs}\implies 10\pi ~\frac{rad}{secs}\approx 31.42~\frac{rad}{secs}$

Find the value of each variable. If you answer is not an integer, express it in simplest rauitar

Marrrta [24]

This is one of the special right triangles known as a 30, 60, 90 triangle. (Characterized by its angles)

In these triangles, the shortest leg is HALF the length of the hypotenuse.

The longest leg is (√3) times the length of the short leg.

Therefore, the shortest leg is 20, and the longest leg is 20(√3)

FINAL ANSWER:

SHORT LEG: 20 units

LONG LEG: 20√3 units

Through (-1,5) , perp to y =1/9x+2 write the slope intercept form for the equation

ycow [4]

Answer:

y=-9x-4

Step-by-step explanation:

Perpendicular lines meet the following condition:

m2*m1= -1 (a)

where m is the slope of a line

m1 is given through equation of line 1, y =1/9 x+2

m2 must be -9 -> from eq. (a)

The Line has the following equation: y=mx+b, where m=-9 and the b is the interception with y axis.

Evaluating the above equation in (-1,5) we have the following equation

5= -9*(-1)+b, we have b=-4

The line has the following equation

y=-9x-4

A test has 20 true/false questions. What is the probability that a student passes the test if they guess the answers? Passing me

Minchanka [31]

Using the binomial distribution, it is found that:

The probability that the student will get 15 correct questions in this test by guessing is 0.0207 = 2.07%.

For each question, there are only two possible outcomes, either the guess is correct, or it is not. The guess on a question is independent of any other question, hence, the binomial distribution is used to solve this question.

Binomial probability distribution

$P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}$
