Last week at the park Haeather ran 4 miles in 48 minutes when she runs her next race she Hope's to improve her time by 2 minutes per mile
Last week at the park what was haeather rate of speed in miles per hour
Answer:
Haeather ran at a speed of 5 miles per hour.
Step-by-step explanation:
Given that last week at the park Haeather ran 4 miles in 48 minutes, to determine what was Haeather rate of speed in miles per hour the following mathematical calculation must be performed:
48/4 = 12
Thus, Haeather ran 1 mile every 12 minutes.
60/12 = 5
1 x 5 = 5
Therefore, Haeather ran at a speed of 5 miles per hour.

(10 A person flying a kite has released
123 ft of string. The string makes an
angle of 21 degrees with the ground. How high
is the kite ?
Answer:
The kite is about 44.1 feet high.
Step-by-step explanation
Since you are trying to find the height, you would draw a triangle to diagram which sides you need to use. The 123 ft of string would be the hypotenuse of the triangle while the 21 degrees is the theta. You are trying to find the height and from the theta that would be the opposite side so you would use sine because you are using opposite and hypotenuse.
sin21=x/123
You have sin of 21 because that is the angle measure, then opposite over hypotenuse which is x/123.
You then multiply both sides by 123 to get the variable of x alone on one side.
123sin21=x
Then just plug this into your calculator and round to the nearest tenth and you get 44.1 feet.

Leo has purchased a fee-for-service health insurance plan from Leroux Health Insurance. Plan A includes a $225.00 monthly premium and an annual deductible of $5,500.00 (not including co-pays). Except for chronic back pain, Leo is a fairly healthy man. He visits his primary care physician four times a year on scheduled visits. He sees a chiropractic specialist every two weeks to help with his lower back pain. He has no current prescriptions that need refilling regularly. Assuming Leo maintains his regular visits with his primary care physician and his chiropractor, and avoids any trips to the emergency room or urgent care, how much will Leo pay in health care related fees this year, including his premium payments? See the table below: *

Answer:
= 20 square units
Step-by-step explanation:
First we calculate the obvious square without the extra points. The side length of the square is four; therefore, the area of the square is 16 square units. The points are each 1 square unit as they split the squares down the midde. In total, 16 + 4(1) = 20.
The dimensions of a rectangular sandbox are 4x + 2 by 2x + 4. The dimensions of a rectangular garden are 3x - 2 by x + 4. Which

OB. 10x2 + 8
o C. 8x2 + 20x + 8
O D. 11x2 + 30x
Answer:
A. 5x²+10x+16
Step-by-step explanation:
Sandbox Dimensions - Garden Dimensions
(4x+2)(2x+4) - (3x-2)(x+4)
(8x²+20x+8) - (3x²+10x-8)

An air-conditioning repair technician claims to complete 67% of repairs in under an hour. A random sample of 31
repairs was chosen, and 22 of those were completed in under an hour. Let p = the proportion of the random
sample that were completed in under an hour.
The probability that 71% or more of this technician's repairs were completed in under an hour is 0.317. Does this
result provide convincing evidence against the technician's claim?
Yes, it is expected that 22 of the units at most will be repaired in under an hour.
Yes, the probability of seeing the sample result is so far from what is expected that the probability of it occurring by
chance alone is very unlikely.
No, there is a very small chance of seeing the sample result. It is unlikely to occur by chance alone.
No, the difference between the sample result and what is expected is not extreme enough. The probability of it
occurring by chance alone is not unlikely.
Answer:
D No, the difference between the sample result and what is expected is not extreme enough. The probability of it occurring by chance alone is not unlikely.
Step-by-step explanation:

repairs was chosen, and 22 of those were completed in under an hour. Let p = the proportion of the random.
The sample was completed in under an hour.
What is the probability?Probability means possibility. It is a branch of mathematics that deals with the occurrence of a random event. The value is expressed from zero to one.
The probability that 71% or more of this technician's repairs were completed in under an hour is 0.317.

Is 3.13 greater than 3.12
Answer:
yes
Step-by-step explanation:
if we figure out the difference between the two numbers by subtracting one from the other, if the product comes out positive, then the number you subtracted from is greater, if the product comes up negative, then the number you subtracted from is lesser
say we did 3.13 as our first number
3.13 - 3.12 = 0.01
this means that 3.13 is greater by 0.01, if we switch the two numbers however...
3.12 - 3.13 = -0.01
then that means that 3.12 is lesser by 0.01
i hope this makes sence, working with decimals may get tricky sometimes lol
Yes, 3.13 is greater than 3.12.
What is decimal?A decimal number is a number in which whole number part is separated from a decimal.
How to find greater number?We have been given two numbers 3.13 and 3.12 and we have to find the greater number from these two numbers. When two numbers are in decimal then firstly we have to see the digit before the decimal, the number having large digit becomes large. If the digit before decimal is same in both numbers then we have to see whether the first digit after the decimal is greater or not. If this digit is also same then we will move towards left and so on.
In the numbers 3.12 and 3.13, 3 which is second digit after decimal is greater than 2. So 3.13 is greater than 3.12.
Hence 3.13 is greater than 3.12.

A. 10n+30<500
B. 10n+30≥500
C. 30n+10≤500
D. 30n+10>500
Answer:
The correct answer is 10n ≥ 470.
Step-by-step explanation:
Since, the school club wants to collect at least 500 canned goods, then we know that they don't want to collect any less: they must collet 500 or more canned goods.
They already collected 30 canned goods, therefore we can subtract this quantity from out goal.
500 - 30 = 470
Since there are 10 club members, the number of members multiplied by "n" the minimum amount of canned goods that they can collect, will equal the total amount of canned goods that they need.
