how for is Blaine's house if you must drive 6.5 hours through the woods at an average of 45mph to get there?

1 answer:

3 0

Six and a half hours at a speed of 45 mph. 45 mph is forty five miles per hour. since there are six full hours, multiply six (time) by speed (45) to get the distance within the six full hours, which is 270 miles. you also have an additional half hour at a 45 mph speed, so rather than going 45 miles in one hour, you for half an hour, meaning you go 22.5 miles. add these two together (270 + 22.5) to get 292.5 miles. a faster way to get to this would be to multiply 6.5 * 45. hole this helps!

400 pens in a shop. 40% are black, 20% are blue, 10% are yellow. If the remaining pens are red, how do I find the percentage of

Drupady [299]

Answer:

30 percent are red pens

Step-by-step explanation:

40 percent plus 20 percent plus 10 percent is 70 percent. That means 70 percent of the pens in the shop are not red and the other 30 percent are. If you want to know the exact amount do 30 percent of 400 which is 400 divided by 3.33 which is approximatly 120.

The union of two events A and B is the event that: a) The intersection of A and B does not occur. b) Both A and B occur. c) Eith

Wewaii [24]

Answer:

c) Either A or B or both occur.

Step-by-step explanation:

Suppose that we have two events

Event A

Event B

We have that:

$A = a + (A \cap B)$

In which a a happens and b does not and $A \cap B$ is the probability that aboth events happen

By the same logic, we have that:

$B = b + (A \cap B)$

The union of events A and B is:

$(A \cup B) = a + b + (A \cap B)$

Which includes either one of them or both.

So the correct answer is:

c) Either A or B or both occur.

Joshua’s computer loan statement said he would pay $1,244.34 in simple interest for a three-year loan at 12.4%. How much did Jos

rusak2 [61]

Answer: Josh borrowed $ 876 to buy the computer.

Step-by-step explanation:

Formula for simple interest : I = Prt

, where P = principal amount

r= rate of interest ( in decimal)

t=time (in years)

Total amount with simple interest to pay : A = P+I

⇒ A = P +Prt

⇒ A = P(1 +rt) (i)

As per given , A = $1,244.34

r= 12.4% = 0.124

t= 3 years

Now, put these values in (i) , we get

$1244.34=P(1+0.124)^3\\\\\Rightarrow\ 1244.34=P(1.124)^3\\\\\Rightarrow\ 1244.34=P(1.420034624)\\\\\Rightarrow\ P=\dfrac{1244.34}{1.420034624}\\\\\Rightarrow\ P=876.27$

Hence, Josh borrowed $ 876 to buy the computer.

What is the difference between a function and not a function<br> ALGEBRA

RideAnS [48]

<span>A function is a relation between a set of inputs and a set outputs. They have to be related to each other...
For example
1, 2, 3, 4, 5
2, 4, 6, 8, 10
Those two are a function.
Hope this Helps!</span>
