Answer:
11/8 or 1 3/8
Step-by-step explanation:
first you have to change the denominator to 8 in the 3/4, so that means you have to change the numerator too.
that gets you 6/8, so the new equation is
6/8+5/8
you only have to add the numerators, so it gives you 11/8.
to change it to a mixed number, all you have to do is find how many whole numbers (aka 8/8 in this situation) go into your improper fraction, and there is 1 in ours. you set that aside and you get 3/8 left over. You put those together and get 1 3/8
hope this helps! have a nice day!

Step-by-step explanation:
A Cd usually sells for 11 if the XD is 10% of abs sales tax are 6% What is the total price of the cd including tax
9514 1404 393
Answer:
$10.49
Step-by-step explanation:
Maybe $11 CDs are selling at a 10% discount with 6% sales tax. Then the total price is ...
$11.00 × (1 -10%) × (1 +6%) = $11.00(0.90)(1.06) ≈ $10.49
The price with discount and tax is $10.49.

option D is correct answer. ( 2, 2)
Decide whether each one of these sets of data is discrete or continuous.
a) the weight of a puppy
b) the number of puppies in a litter
c) a person's temperature
d) the dress sizes of women
Answer:
A set is continuos if the values of the set can be any value in the given ranges
A set is discrete if the values of the set are finite and separate.
Than:
a) The weight of a puppy.
The weight of a puppy can be any value between 0 kg and a given maximum weight, then this is a continuous set.
b) The number of puppies in a litter.
Here we can have only whole numbers, for example, we can not have 7.34321 puppies in the litter, so this is a discrete set.
c) A person's temperature.
Temperature can be any value in a given range, so this is a continuous set.
d) The dress sizes of women.
Normally, there is a given set of dress sizes like s, l, xl, etc.
So in general, this is a discrete set. (While the actual "size" of a dress can take a lot more values than those ones, but this still is a discrete set)

PLEASE GEOMETRY HELP WILL MARK BRAINLIEST!!!
Answer:
120
Step-by-step explanation:
First we can find the value of each exterior angle
The sum of the exterior angles is 360
because a hexagon has 6 congruent exterior angles we divide 360 by 6
360/6=60 so each exterior angle is equal to 60 degrees
the exterior angle and interior angles of any regular polygon are supplementary angles ( meaning the sum of the two is 180) so to calculate the interior angle we subtract 60 from 180
180-60=120 so each measure of the interior angle of a hexagon is 120 degrees

x=
Answer:
x = 3√7
Step-by-step explanation:
The Pythagorean theorem states that in a right triangle, the sum of the legs squared and added together is equal to the hypotenuse (the longest side and the one across the 90° angle)
If the legs are a and b, respectfully, and the hypotenuse is c, the equation would be:
a² + b² = c²
Let's apply this to the problem given.
9² + x² = 12²
Simplify.
81 + x² = 144
Subtract 81 from both sides.
x² = 63
Take the square root.
√(x²) = √63 = √(9 * 7) = √(3² * 7)
x = 3√7
Check the answer.
9² + (3√7)² = 12²
81 + 9 * 7 = 144
81 + 63 = 144
144 = 144
Thus, the answer is correct.
I hope this helps! Feel free to ask any questions! :)
A tank that is 40% full contains 648 gallons of water. How much water is in the tank when the tank is at full capacity (100%)?
Answer: 1620 gallons of water
Step-by-step explanation:
Let the water that is in the tank when the tank is at full capacity be represented by x.
Therefore, 40% of x = 648
40% × x = 648
40/100 × x = 648
0.4 × x = 648
0.4x = 648
x = 648/0.4
x = 1620
The answer is 1620 gallons

1. Solve triangle ABC if A = 42.3º, b = 12.9 meters, and c = 15.4 meters.
this is trigonometry, you have to use the cosine law to solve it
Answer:
a = 10.36m
B = 47.7º
C = 90º
Step-by-step explanation:
we know the angle of A so we do the sin of A; Spoiler: its 0.67
0.67 = a / 15.4
0.67 * 15.4 = a
a = 10.36
----------
B = 90 - 42.3 = 47.7º
please help this is TIMED!
Answer:
angle 1 = 51 degrees
angle 2 = 18 degrees
angle 3 = 123 degrees
angle 4 = 39 degrees
Step-by-step explanation:
angle 2 = 90-72 = 18
angle 3 = 180 - 57 = 123
angle 4 = 180 - 123 - 18 = 39
angle 1 = 90 - 39 = 51

Step-by-step explanation:
Lydia invested $83,000 in an account paying an interest rate of 6.7% compounded
monthly. Assuming no deposits or withdrawals are made, how long would it take, to
the nearest year, for the value of the account to reach $210,100?
Answer:
14
Step-by-step explanation:
The required time for Lydia's account to reach $210,100 is 13.9 years.
What is compound interest?Compound interest is the interest on deposits computed on both the initial principal and the interest earned over time.
First, convert R as a percent to r as a decimal
r = R/100
r = 6.7/100
r = 0.067 per year,
Then, solve the equation for t
t = ln(A/P) / n[ln(1 + r/n)]
t = ln(210,100/83,000) / ( 12 × [ln(1 + 0.067/12)] )
t = ln(210,100/83,000) / ( 12 × [ln(1 + 0.0055)] )
t = 13.9 years
Thus, the required time for Lydia's account to reach $210,100 is 13.9 years.

Ed's new car has a value of $23,500, but it is expected to depreciate at a rate of 7.5% per year. If you were to write an exponential decay function to represent this situation, what would the decay factor be?
Answer:
0.925 or 92.5%
Step-by-step explanation:
y=a(1-b)^x
decay factor is 1-b <- and the part we care about
b is 7.5%=0.075
1-0.075
=0.925
I'm a little rusty on exponential rates, but I hope this helps!
The decay factor for the car will be equal to 0.925 or 92.5%
What is an exponential expression?Powers can simply be expressed in concise form using exponential expressions. The exponent shows how many times the base has been multiplied. Since 2 is the "base" and 5 is the "exponent," it can be written as 2 x 2x 2 x 2=25 for the number 32. This phrase should be understood as "two to the fifth power."
Given that Ed's new car has a value of $23,500, it is expected to depreciate at a rate of 7.5% per year.
The decay factor will be calculated as,
[tex]y=a(1-b)^x[/tex]
b is 7.5%=0.075
Decay factor = 1-0.075
Decay factor = 0.925

Betsy drove from london to wolverhampton.it took her 2.5 hours at an average speed of 56 miles per hour.Mac drove the same journy by motor bike.It took him 2 hours.Assuming that both took the same route,work out Mac's average speed in mph.
Answer:
44.8 mph
Step-by-step explanation:
Betsy drove from london to wolverhampton.it took her 2.5 hours at an average speed of 56 miles per hour.Mac drove the same journy by motor bike.It took him 2 hours.Assuming that both took the same route,work out Mac's average speed in mph.
The above question is solved using Proportion method
2.5 hours = 56 mph
2 hours = x mph
Cross Multiply
2.5 hours × x mph = 2 hours × 56 mph
x mph = 2 hours × 56 mph/2.5 hours
x mph = 44.8 mph
Therefore, Mac's average speed = 44.8 mph
