Answer:
Monica = 48.50
Samuel = 24.25
Kara = 17.25
Step-by-step explanation:
First you write equations as you are reading the text:
m = 2s ("Monica earned twice as much as Samuel")
s = k+7 ("Samual earned 7 more than Kara")
m = 48.50
Next, you convert these equations to solve for s and k respectively.
So, if m=2s, then s=m/2:
s = m/2 = 24.25
Likewise, if s=k+7, then k=s-7
k = s-7 = 17.25
The difference between greatest and least is 48.50 - 17.25 = 31.25

how many solution does following equtitions have 7x+21=21
Answers
One solution.
[tex]7x + 21 = 21 \\ 7x = 21 - 21 \\ 7x = 0 \\ x = 0[/tex]
If we can solve for the value of x. Then the solution would be one only for system of linear equations.
For your information, When the equation is true or rather say that both sides are the same, the solution will be infinite.
When the equation is false or rather say that both sides have different number or value then there won't be any solutions.
write a rational number which has no reciprocal or multiplicative inverse.
Answers
Answer:
0.
Step-by-step explanation:
0 is the only number that has no reciprocal or multiplicative inverse.
A reciprocal / multiplicative inverse of a number means a number that when multiplied by the original number will equate to 1.
However, no matter what you multiply with 0, it will never be 1.
Hence, the answer is 0.

The distribution of height of adult american women is approximately normal with a mean of 65.5 inches and a standard deviation of 2.5 inches what percentage of women are taller than 70.5 inches?
Answers
Answer:
2.275%
Step-by-step explanation:
We start by calculating the z-score
Mathematically;
z-score = (x-mean)SD
here, x = 70.5
mean = 65.5
SD = 2.5
Substituting these values;
z = (70.5-65.5)/2.5
= 5/2.5 = 2
So we want to calculate the probability that;
P( z> 2)
We check the standard normal distribution table for this
That will be
0.02275
In percentage, this is 2.275 %

Terry flips a coin 150 times.Make a prediction that the coin will come up tales
A Exactly 300
B Close to but not exactly 300
C Exactly 75
D Close to but not exactly 75
Answers
Answer:
its either C or D
Step-by-step explanation:
there are 2 possible outcomes for getting either heads or tails so if we divided 150 by 2 we get 75, so about 75 times you could get tails.
so maybe it is D, but im not sure
Because when you divide 150 by 2= 75
You divide by two because it’s either heads or tails.
It wouldn’t be exactly 75 either because it’s just a game of chance.

Luis has $660 in his savings account earning 4 1/2 % interest. How much interest will he earn in 2 years? How much money will be in the account?
Answers
Answer: $59.40 of interest in 2 years, $719.40 in total
Step-by-step explanation:
If you would divide $660 by $100 then 1% of that amount would be $6.60. Assuming it is 4.5% from your question, if you would multiply the amount above then Luis would get $29.70 per year. Also assuming that his savings account isn't changed over time, you would multiply 2 to get $59.40 which is the total amount of interest money earned in 2 years. Add that amount to $660 and you would get $719.40 as the second part of the answer.

find the measure of the arc mDE=
Answers
Answer:
90°
Step-by-step explanation:
Hope it helps!!
The measure of Arc is 90 degree.
What is Arc?An "arc" is a smooth curve that connects two points in mathematics. In general, an arc is a section of a circle. It is essentially a portion of a circle's circumference.
A circle's arc is defined as a portion or segment of its circumference. A chord of a circle is a straight line that can be created by connecting the two ends of an arc. A semicircular arc is one whose length is exactly half that of a circle.
Since, m(arc EF) = Angle subtended by the arc EF at the center
= 146°
m(arc DE) = 90°
Thus, the measure of arc DE is 90 degree.
