A biker travels 5 feet in 0.5 seconds. At this exact speed, how far will the biker travel in a minute?

1 answer:

3 0

A minute has 60 seconds, therefore we will deal with seconds now And since we have it that the biker travels 5 feet every 0.5 seconds, lets multiply that by 2 to get the traveled distance per second to make it easier 5*2=10 Finally, multiply 10 feet by 60 seconds(1 minute) = 600 feet

-5x -10 >30 help Hehehehehe.

Mnenie [13.5K]

Answer:

x<-8

Step-by-step explanation:

-5x-10>30

(add 10 to both sides)

-5x-10+10>30+10

-5x>40

$\frac{-5x}{-1}$ < $\frac{40}{-1}$

(dividing through by -1 changes the sign of the inequality from "<" to ">")

5x<-40

(dividing through by 5)

$\frac{5x}{5}$ < $\frac{-40}{5\\}$

x<-8

Parallel lines form when a plane and a cylinder intersects.

Many angles are also produces. And then, the produced angles will together form certain pairs of corresponding angles.

Good luck :)

Complete the pairs of corresponding parts if ABD congruent to EFC.

Alchen [17]

Remember the notation..

When you have a triangle called ABD, the angles may be called in theses equivalent ways>

angle A is equivalent to ∠ DAB
angle B is equivalent to ∠ ABD
angle D is equivalen to ∠ BDA

Then given that the two triangles are congruent, you can say an

angle B = angle F = ∠ EFC

So the answer is the last option of the list.

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:

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