A store bought a tent for $230 andmarked it up 65%. The store sells thetent with an 8% tax, what is the totalcost of the tent?

Len [333]

The cost for buying the tent is $230.

65% was increasesd for selling. Then the rate is

$\begin{gathered} 230\times\frac{65}{100}=14.95 \\ So,\text{ the marked price=230+14.95=}244.95 \end{gathered}$

The tax is 8%. So this is from the marked price.

$\begin{gathered} \frac{8}{100}\times244.95=19.56 \\ 244.95-19.56=225.39 \end{gathered}$

Therefore the total cost of the tent is $225.39.

The probability that a newborn baby at the hospital is female is 50%. What is the probability that at least 2 babies of 3 childr

Readme [11.4K]

Answer:

0.25 is the probability

Step-by-step explanation:

In this question, we are tasked with calculating the probability that in a hospital on a certain day, at least 2 out of three babies born that day are female.

To calculate the probability , let’s list out some needed facts;

Let the probability of having a baby girl be g = 50% = 50/100 = 1/2 = 0.5

The probability of having a boy b will be 1-g = 1-0.5 = 0.5

Now, we have 3 babies and we want to find the probability of at lest two being girl.

Mathematically that would be ; ggb or ggg

since we are having at lest 2 girls

For the ggb, we have ; 0.5 * 0.5 * 0.5 = 0.125

For the ggg we have 0.5 * 0.5 * 0.5 = 0.125

In probability, once we have or, we add.

Thus 0.125 + 0.125 = 0.25

Solve for x.<br> 13<br> =(5x+ 6)/8 + <br> (5x+4)/4

valkas [14]

Answer: x=6

Step-by-step explanation:

To solve for x, we want to isolate the variable.

$\frac{5x+6}{8} +\frac{5x+4}{4} =13$ [get common denominator]

$\frac{5x+6}{8} +\frac{2(5x+4)}{8} =13$ [add fractions]

$\frac{5x+6+10x+8}{y} =13$ [combine like terms]

$\frac{15x+14}{8} =13$ [multiply both sides by 8]

$15x+14=104$ [subtract both sides by 14]

$15x=90\\$ [divide both sides by 15]

$x=6$

Now, we know that x=6.

Y+2x=3 find the ordered pair

Digiron [165]

Answer:

y and x = 1

Step-by-step explanation:

If the answer is 3, then you would have to multiply 2 by 1 to get 2 then add 1 to get 3, so its possible that y and x are both 1.

Both figures are similar. What is the length of the missing side?

Lesechka [4]

Answer:

I'm not 100% sure, but the rectangle on the left is 5 smaller on the top, so it might also be 5 smaller than the side if it shrunk as a whole...lol
