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.

(6,5), 7x-3y=5 find the equation of the line that contains the given point and is parallel to the line. write the equation in slope intercept form
Answers
Answer:
y = (7/3)x - 9
Step-by-step explanation:
1. Convert given equation to y=mx+b form --> y = (7/3)x - 5/3
2. Equation of new line --> y = (7/3)x + b
Note: 7/3 is the slope and for lines to be parallel they need the same slope so both equations have 7/3.3. Plug in given values --> 5 = (7/3)(6) + b
4. Solve for b --> b = 5 - 14 b = -9
5. New line --> y = (7/3)x - 9

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.

Option B gives the best value.
What is a circle?
'A circle is a shape consisting of all points in a plane that are at a given distance from a given point which is the center.'
According to the given problem,
Radius = 8 inches
Diameter = 16 inches
Considering a pizza is a circle and the area of a circle increases with the square of the radius.
However 45 degrees being less inclined than 30 degrees.
Hence, a slice with a radius of 8 inches, central angle of 45 degrees gives the best value for $ 2 per slice.

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 %
Givethanks, an Indian, wants to have a turkey dinner. He and his “dog”, Wolf, go looking for a turkey. While on this turkey hunt, they come across a field of corn. Givethanks just has to have some of the corn and picks some to take home. While in the corn field, Givethanks spots the biggest turkey he has ever seen and captures it. On the way home to his village, Givethanks and Wolf come to a river where there is a small boat that will only fit Givethanks and one other thing. Now, Givethanks wants to get Wolf, the turkey and the corn across the river, but Wolf will eat the turkey if they are left alone and the turkey will eat the corn if it is left alone with the corn.
Your Task: Figure out how Givethanks will get Wolf, the turkey and the corn across the river. You must show how you feel he can accomplish this task. You must write a paragraph explaining how you feel you can accomplish this task.
I need help with this.
Answers
Answer: The man and the turkey cross the river, (the wolf and corn are safe together), he leaves the turkey on the other side and goes back across.
The man then takes the wolf across the river, and since he can't leave the wolf and turkey together, he brings the turkey back.
Again, since the turkey and corn can't be left together, he leaves the turkey and he takes the corn across and leaves it with the wolf.
He then returns to pick up the turkey and heads across the river one last time.

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.
