Luis rides his bicycle 34 mile in 15 minutes, or 14 hour, along the bike trail.
Assuming he rides at a constant rate, what is his speed, in miles per hour? Use the table to help find the answer.
Enter your answer in the box.
Miles 34 ?
Hours 14 ?
miles per hour needs to be a fraction
Answer:
136/hour
Step-by-step explanation:
15*4=60. we need to know this because we need to know by the hour not by the minute. so 34*4=136. they travel 136 miles per hour. in fraction form this is 136 miles/hour (this is also called a ratio). for 14 hours is a red herring (unneeded) unless you need to refer to this for many problems

PLEASE HURRY 50 points There are three red, four blue, and three green marbles. What is the probability of selecting a blue marble first, replacing the marble, then selecting a green marble? Assume that each is equally likely to be chosen.
7/100
3/25
7/20
3/5
Answer:
1/13
Step-by-step explanation:
the answer is up at the top
Answer:
Here's an example to help guide you to answer this question dear.
Step-by-step explanation:
A jar contains 10 red marbles, 4 white marbles, and 2 blue marbles. Two are drawn in sequence, not replacing after each draw.
Quantity A is greater.
Why?
Note that there are 16 total marbles. A is simply a set of sequential events. On the first, you have 10/16 chances to draw a red. Supposing this red is not replaced, the chance of drawing a second red will be 9/15; therefore, the probability of A is (10/16) * (9/15) = 0.375. Event B is translated into 2 events: Blue + (White or Red) or (White or Red) + Blue. The probabilities of each of these events, added together would be (2/16) * (14/15) + (14/16) * (2/15) = 0.2333333333; therefore, A is more probable.
Donna bought 5 bags of dog treats for $14.00. What is the cost per bag of dog treats?
Answer:
2.8
Step-by-step explanation:
14 divided by 5=2.8
Hope this helps you! <3
Answer:
$2.80
Step-by-step explanation:
You need to divide 14 by 5 to get how many dollars it costs. An easy way to do this do 14 * 2 / 10 = 2.80. So it costs $2.80 per bag of dog treats.
Megan ordered her favorite pizza with 12 slices.
a) How many slices is 100%? Show your answer on the double number line.
b) She ate 75% of the whole pizza. How many pizza slices did she eat?
Answer:
A maybe???????
Step-by-step explanation:
Answer:
a.) 12 slices b.) 9 slices
Step-by-step explanation:

b.) If you take 12(the number of slices) and divide it by .75(the percent she ate) then you would get 9 slices.
Liz earns a salary of $2,300 per month, plus a commission 5% of her sales. She wants to earn at least $2,500 this month. Enter an inequality to find amounts of sales that will meet her goal. Identify what your variable represents. Enter the commission rate as a decimal.
Answer:
she needs to earn at least $200 more to equal $2,700, so
200=x($amount of needed sales) * .06
200/.06=x
$3,333=x is sales needed to meet goal
variable is $ amount of sales needed to earn $2,700 this month.
Commission rate as decimal=.06
Inequality that represents is...
x> or = $3,333
In the weeks after a chick hatches, its mass increases by a factor of 2.5 to become 180 grams. What is the chick’s mass at hatching?
Write and solve an equation to show the answer.
Explain when to use division and when to use multiplication to solve an equation. Give examples to support your answer
Answer: 1,796
Step-by-step explanation:
We are given that : At the chicken ranch this morning there were 7,149 chicks.
i.e. The number of new chicks before today = 7,149
Later today some more chicks hatched. now the ranch has 8,945 chicks.
i.e. The number of new chicks after today = 8,945
Then, By Subtraction operation
Number of new chicks hatched today = ( Number of new chicks after today) - (Number of new chicks before today )
= 8,945- 7,149 = 1,796
Therefore , the number of new chicks hatched today = 1,796

Isabella is calculating the interest earned on a deposit of $3000 in an account that earns 4% simple interest after 6 years I=prt I= 3000(.04)(6). A. I=3,720. Isabella determines that her deposit will then be worth 6,720.00. Explain what isabela did incorrect . B. what is the correct amount of interest. please show the work
Answer:
Interest = $ 720
Step-by-step explanation:
p = $ 3000
r = 4%
t = 6
I = [tex]3000*\frac{4}{100}*6\\[/tex]
= 30 *4 * 6
= 720
Amount = p + I
= 3000 + 720
= $ 3720

I believe it is B because -5x-23[tex]\leq[/tex]-18 equals -1.
Answer:
B) x≥-1

-5x≤5
x≥-1 (When you multiply or divide both sides by a negative number, the sign switches around)
During a football game, a concession stand sold a family 2 hamburgers and 2 hotdogs for a total of $13. It sold another family 2 hamburgers and 5 hotdogs for a total of $16. What are the prices of a hamburger and a hotdog?
Answer:
The price of each hamburger is $3
The price of each hot dogs is $2 .
Step-by-step explanation:
Given as :
The total price of 3 hamburger and 2 hot dogs = $13
The total price of 2 hamburger and 5 hot dogs = $16
Let The price of each hamburger = $x
Let The price of each hot dogs = $y
Now, According to question
3 x + 2 y = 13 .........A
2 x + 5 y = 16 .......B
Now, Solving to eq A and B
3 × (2 x + 5 y ) - 2 × (3 x + 2 y ) = 3 × 16 - 2 × 13
Or, (6 x + 15 y) - (6 x + 4 y) = 48 - 26
Or, (6 x - 6 x) + (15 y - 4 y) = 22
Or, 0 + 11 y = 22
∴ y =
i.e y = $2
so, The price of each hot dogs = y = $2
Now, Put the value of y into eq B
i.e 2 x + 5 y = 16
or, 2 x + 5 × 2 = 16
or, 2 x = 16 - 10
or, 2 x = 6
∴ x =
i.e x = $3
So, The price of each hamburger = x = $3
Hence, The price of each hamburger is $3 and The price of each hot dogs is $2 . Answer
Answer:
the hamburgers are 6.50 and hot dogs are 3 dollars
Step-by-step explanation:
