zysi [14]

Answer:

Wood\ remain = 1\frac{3}{4}

Step-by-step explanation:

Note; given question is incomplete

Size of pieces = 1\frac{2}{3} ,2\frac{3}{4} , 3\frac{5}{6}

Given:

Size of wood = 10 ft

Find:

How much wood remain

Computation:

Wood remain = 10-1\frac{2}{3} -2\frac{3}{4} - 3\frac{5}{6}

Wood\  remain = 10-\frac{5}{3} -\frac{11}{4} - \frac{23}{6}\\\\Wood\ remain = 10 - \frac{99}{12} \\\\Wood\ remain = 1\frac{3}{4}

A rectangular yard is 25 ft by 19 ft. The yard is covered with grass except for a
soldier1979 [14.2K]

Answer:

There is 384.75 sq feet area of grass in the rectangular yard.

Step-by-step explanation:

The dimensions of the rectangular yard = 25 ft x 19 ft

The Area of the yard =  LENGTH x WIDTH

                                  = 25 ft x 19 ft

                                  = 475 sq feet

or, the area of the rectangular yard =  475 sq feet

Now, the side of the square covered with flower garden = 9.5  feet

So, area of the flower garden =  9.5 ft x 9.5 ft = 90.25 sq ft

Now, Area Covered with Grass = Total area of Yard - Area of flower garden

 =  475 sq feet   -  90.25 sq feet

 =   384.75 sq feet

or, the area covered with grass = 384.75 sq feet

Hence, there is 384.75 sq feet area of grass in the rectangular yard.

Please help me with this probability problem.
lesya692 [45]

Answer:

0.308

Step-by-step explanation:

You have 8 nickels and 6 dimes. 8 + 6 = 14.

You know both of the coins you have picked are nickels so you will have to find the probability of picking a nickel and then another nickel.

First time: \frac{8}{14} is the probability of picking a nickel the first time.

Second time: Since you don't have a nickel in your pocket anymore, you now have 7 nickels and 6 six dimes in your pocket. Together you have 13 coins. You have 7 nickels so you have a \frac{7}{13} chance of picking another nickel out of your pocket.

To find the probability of this event you do \frac{8}{14} * \frac{7}{13} because to find the probability of A and B you do P(A) multiplied by P(B). If you wanted to find the probability of getting A or B you would add together instead of multiplying.

Multiplying these together gets you 0.307692... which is 0.308 rounded.

C. The y-intercept represents how far away she is at time = 0, meaning before she started traveling home. Therefore it must be a single value rather than a per-minute rate, and it must be measured in miles since it's a measure of distance. C is the only answer that fits.
