Answer:

$\frac{5}{4}$

Step-by-step explanation:

We need to find the formula of line c

$\left \{ {{a*2+b=1} \atop {6*a+b=6} \right.$

Subtract these two

-4*a=-5

a= $\frac{5}{4}$

And lies c and d will be paraller if $a_{c}= a_{d}$

so $a_{d}$ = $\frac{5}{4}$

And that's the slope to line d

Answer:

$V=36.63cm^3$

Step-by-step explanation:

Volume formula for rectangular prism is $V=lwh$

Volume = length * width * height

Sammy has x flavors of candies with which to make goody bags for Frank's birthday party. Sammy tosses out y flavors, because he

harkovskaia [24]

Answer:

$^{(x-y)}C_{10}=\frac{(x-y)!}{10! \times (x-y-10)!}$

Step-by-step explanation:

Total flavors Sammy initially had = x

Number of flavors Sammy throw away = y

After throwing away y flavors, the number of flavors Sammy will be left with = x - y

He needs to make 10-flavor bags from these (x - y) flavors. In order words he needs to chose 10 flavors for each bag from(x - y) flavors. The order of selection is not important here, so this is a problem of combinations. Also since we have to make selections or small groups, this also indicates that we have to use combinations.

So we need to make combinations of 10 flavors from a total of (x - y) flavors. This can be represented as $^{(x-y)}C_{10}$

The formula for combinations is:

$^{n}C_{r}=\frac{n!}{r!(n-r)!}$

Using the values in this formula, we get:

$^{(x-y)}C_{10}=\frac{(x-y)!}{10! \times (x-y-10)!}$

Sixteen scholars have volunteered to stay after school to help set up for the school musical. The musical director plans to orde

lapo4ka [179]

The director would have to pay $40.47.

If each scholar eats one slice of pizza, then there would be two pizza pies because 8 slices plus another 8 slices in 16

8+8=16

If all of them eat another .5 slice, adding up the halves would equal 8

.5 x 16 = 8

In total, the director would have to buy three pizzas which equals up to our total of $40.47
