Answer:
as formula says:
sum =
in our case n = 10, a1 = 15 and An = 33 so the answer will be:
sum = 10 * (33 + 15)/2 = 10 * 48 / 2 = 10 * 24 = 240
Step-by-step explanation:
Taylor earns $5 each time she walks her neighbor's dog.she has already earned $25.write and solve an equation to find out how many more times taylor needs to walk the dog to earn enough to buy a bike that cost $83.
Answer:
Equation: $83=5w+25 and 12 walks more
Step-by-step explanation:
Here is an equation: $83=5w+25
The $83 on the left represents the $83 goal for the bike (or the total amount of money that Taylor needs)
The 5w represents that Taylor earns $5 per time she walks the dog, with the w being the number of walks.
The +25 shows that Taylor has already earned $25 from walking the dog. (Not sure if you need it, but the $25 took 5 dog walks –– 5•5=25)
To solve:
83 = 5w + 25 –– Subtract 25 from both sides to get the variable term alone
58 = 5w –– Divide both sides by 5 to get w alone
11.6 = w –– Round this up to 12 because you can't really do 3/5 of a walk (this means Taylor needs to walk the dog 12 more times to earn enough to buy the bike)
Check:
83=5w+25 –– Replace w with 12
83=5(12)+25 –– Multiply
83=60+25 –– Add
83=85 –– This shows she will have $2 left over
2x+y=3.4
8x+2y=11.6
what is the value of x?
Answer:
x = 2.2
Step-by-step explanation:
- 4 (2x + y = 3.4) + (8x + 2y = 11.6)
( - 8x - 4y = - 13.6) + (8x + 2y = 11.6)
- 2y = 2
y = - 1
2x + ( -1 ) = 3.4
2x = 4.4
x = 2.2

Answer:
log(35)/log(7)
Step-by-step explanation:
The change of base formula is ...
[tex]\log_b(a)=\dfrac{\log(a)}{\log(b)}[/tex]
You have b=7, a=35, so the rewrite is ...
[tex]\log_7(35)=\boxed{\dfrac{\log(35)}{\log(7)}}[/tex]

Why is it important to understand how variables work, inequalities, and basic awareness of exponents before starting algebra?
Answer:
well algebra is basically about variables.
This is because you're assigning an equation or a number to a letter.

At the same time of day, a man who is 75 inches tall casts a 50-inch shadow and his son casts a 22-inch shadow. What is the son's height?
Answer: i think its 55 but im not sure
Answer:
33 inches tall (see below)
Step-by-step explanation:
You can make a ratio to simplify the situation:
75 in. tall x in. tall
---------------------- = ---------------------
50 in. shadow 22 in. shadow
Cross multiply:
75 (22) = 50 (x)
1650 = 50x
33 = x
x = 33 in. tall

The polar form of the given complex number is:
[tex]W = \sqrt{12}* e^{-i*0.52}[/tex]
How to get the polar form of the complex number?
Here we have:
W = -3 + √3i
To get the polar form we first need the module of W it is:
|W| = √( (-3)^2 + (√3)^2) = √12
And now we need to find the bearing, that is given by the Arctangent of the quotient between the imaginary part and the real part.
Arctan(√3/-3) = -0.52 rad
Then the polar form is:
[tex]W = |W|*e^{-i*0.52} = \sqrt{12}* e^{-i*0.52}[/tex]

the answer is:
180-48= 132°
Answer:
i hope this helps you :))
Step-by-step explanation:
132
Linear pairs always equal 180 degrees.
Therefore, Angle ABC + Angle CBD =180.
We already know Angle CBD is 48.
Therefore, Angle ABC + 48 =180
Subtraction Property of Equality:
Angle ABC = 180-48= 132 Degrees.

Jamie took 12 hours to read a 360 page book. How many pages does Jamie read per hour?
Answer:The required time taken by her to read a 400 page book is 13 hours and 20 minutes.
Step-by-step explanation:Given that Lauren took 12 hours to read a 360 page book.
We are to find the time taken by her to read 400 page book at the same rate.
We will be using the UNITARY method to solve the problem.
We have
Time taken by Lauren to read 360 page book = 12 hours.
So, the time taken by Lauren to read 1 page book will be
Therefore, the time taken by Lauren to read a 400 page book is given by
Thus, the required time taken by her to read a 400 page book is 13 hours and 20 minutes.

There are 9 teachers and 5 aides at the Hills Elementary School. What is the ratio of teachers to all adults?
Answer:
C. [tex]\frac{9}{14}[/tex] , 9:14 , or 9 to 14
Step-by-step explanation:
With there being 9 teachers and 5 aides, the total number of adults is 14, leaving a fraction of [tex]\frac{9}{14}[/tex] , 9 teachers and 14 adults. Checking to simplify, there are no shared values by 9 and 14, so it is in it's simplest form.
