. In April, it rained 1/4 of an inch on 15 different days. How many inches of rain fell
in April
Answer: 3 3/4 inches
Step-by-step explanation:
From the question, we are informed that In April, it rained 1/4 of an inch on 15 different days.
The number of inches of rain that fell in April would be the multiplication of 1/4 by the total number of days. This would be:
= 1/4 × 15
= 15/4
= 3 3/4 inches
Can somebody help me with this one
Answer:
D
Step-by-step explanation:
a^2 cancels out a^5 remaining a^3 denominator
b2 cancels b4 = b2 numerator
c3 cancels out c8 = c5 remaining denominator
36/4 = 9
therefore 9b^2 /a^3 c^5

Solving special systems
{y=1/2x+4
{-1/2x+y=-5
Answer:
no solution
Step-by-step explanation:
Given the 2 equations
y = [tex]\frac{1}{2}[/tex] x + 4 → (1)
- [tex]\frac{1}{2}[/tex] x + y = - 5 → (2)
Substitute y = [tex]\frac{1}{2}[/tex] x + 4 into (2)
- [tex]\frac{1}{2}[/tex] x + [tex]\frac{1}{2}[/tex] x + 4 = - 5 , that is
4 = - 5 ← not possible
This indicates the system has no solution

What are the coordinates of the orthocenter of LMN ?
Answer:
a (1, 2.5)
Step-by-step explanation:
When talking about the orthocenter, you want to make sure that the point you are looking for is in the exact center. Since coordinate N of the x value is 1, we can safely assume that your top two choices are either a and b. B wouldn't work since it is not at the exact center which makes your answer A.

dani rode her bike for 10 hours a day for 8 days . in this time she covered 576 miles. how many miles per day day did did dani average
Answer:
72 miles per day
Step-by-step explanation:
Step one data
we are told that Dani rode for 10 hours per day for 8 days
hence per day, the time taken is = 10 hours
Also,
Hence the average distance covered per day is
=total number of miles/total number of days
=576/8= 72 miles per day
please help me on this, thank u:)
Answer:
the exponent is -8, since when you're dividing these with teh same base, in this case 9, you just have to subtract the exponents, so it's 9^-8
Step-by-step explanation:
9514 1404 393
Answer:
1/9^8
Step-by-step explanation:
The applicable rules of exponents are ...
a^-b = 1/a^b
(a^b)(a^c) = a^(b+c)
__
[tex]\dfrac{9^{-5}}{9^3}=\dfrac{1}{9^5\cdot9^3}=\dfrac{1}{9^{5+3}}=\boxed{\dfrac{1}{9^8}}[/tex]

Bryce took a quiz that consisted of true-or-false questions and multiple-choice questions. The true-or-false questions were worth 1 point each, and the multiple-choice questions were worth 2 points each. Bryce only knows that he answered 8 questions correctly and earned a total of 14 points. To determine the number of each type of question that he answered correctly, he wrote the system of linear equations x + y = 8 and x + 2 y = 14.
Which ordered pair is a solution to this system of linear equations, and what does the ordered pair represent?

The sum of deviation of a certain number of items measured from 2.5 is 50 and from 5.5 is - 250.Find the arthmetic mean
Answer = 3100
Answer:
3
Step-by-step explanation:
Given that :
A1 = 2.5 ; Σdx1 = 50
A2 = 5.5 ; Σdx2 = -250
Mean (m) = A + Σdx/N = 50
m = A + Σdx/N
m - A = Σdx/N
Nm - NA = Σdx
From the parameters given :
Nm - 2.5N = 50 - - - (1)
Nm - 5.5N = - 250 - - - (2)
Subtract (1) from (2)
3N = 300
N = 300/3
N = 100
Put N = 100 in either (1) or (2)
From (2):
100(m) - 5.5(100) = - 250
100m - 550 = - 250
100m = - 250 + 550
100m = 300
m = 300/100
m = 3
Hence, Arithmetic mean = 3

• write the explicit formula. Determine the 20th term of the sequence
Answer:
3486784401
Step-by-step explanation:
a=3, r = T2/T1 = 9/3=3
Tn = ar^(n-1)
T20 = ar^(20-1)
T20 = ar^19

Simon drove through some roadworks where the speed limit was 50 mph. Two cameras recorded the time taken to travel 1200 m through the roadworks as 56 seconds . Was Simon speeding through the roadworks ?
Answer:
[tex]Speed = 21.43m/s[/tex]
Step-by-step explanation:
Given
[tex]Distance = 1200m[/tex] -- of the roadworks
[tex]Time\ Recorded = 56s[/tex]
Required
Determine the speed
In this case:
[tex]Speed = \frac{Distance\ of\ Roadword}{Time\ Captured}[/tex]
[tex]Speed = \frac{1200m}{56s}[/tex]
[tex]Speed = 21.43m/s[/tex] --- approximated

Answer: k = 3
because p - 1 is a factor of the equation
=> at p = 1, p^4 + p² + p - k =0
with p =1, we have: 1 + 1 + 1 - k = 0
⇔ k = 3
Step-by-step explanation:
Answer:
Solution,
since the factor of f(p) = p-1
we know, f(p)= 0
p=1 (from remainder theorem)
now,
f(p) =p^4+p^2+p-k
0= 1^4+1^2+1-k
0= 1+1+1-k
0= 3-k
k=3
Orchids are a family of thousands of types of flowers that all share the same shape. Many gardening clubs are devoted to collecting, studying, and growing orchids, because it is difficult to grow them outside of their natural habitats. Which are scientific questions that can be asked about a collection of different orchid types? Check all that apply. Which type needs the highest temperatures to grow in? Which type has the most beautiful colors? Do all of the types make food the same way? Do all of the types deserve the same amount of admiration? How can someone decide which type makes the best gift? How long does it take for a specific type to make its seeds?
Answer:
The correct options are;
1) Which type needs the highest temperature to grow
2) Do all of the types make food the same way
3) How long does it take for a specific type to make seeds
Step-by-step explanation:
The number of types of species in the orchid family = Several thousand
The tasks the gardening clubs are devoted to = Collecting, Studying, and growing of the orchids
The manner of the growth of the orchids = Difficulty observed in growing outside the orchid's natural habitat
Scientific questions are objective questions that are measurable, well defined about parameters that can be controlled which can be answered by means of an experiment and meant to provide a deeper understanding of the nature of the world around us
Therefore, the scientific questions that can be asked about a collection of different orchid types are;
1) Which type needs the highest temperature to grow
The above is a question that has a defined parameter (temperature) which is measurable and the answer can be provided by experimenting
2) Do all of the types make food the same way
An experiment with different orchid types will provide an answer to the above question
3) How long does it take for a specific type to make seeds
The length of time for it takes the seed to grow is measurable within an experiment.
Answ do all types make food the same way? which type needs higher tempurturs to grow and do all types make food the same way
