Semicircle M has a radius of 15 inches. If an ant walks from A to B directly along diameter AB and a beetle
walks from A to B around ACB. how much farther, to the nearest tenth of an inch, does the beetle walk?
(1) 17.1
(2) 32.1
(3) 64.2
(4) 79.2
Answer:
A,17.1 in
Step-by-step explanation:
circumference of sphere=2πr
Beetle walks=πr=π×15=15π=15×3.14≈47.1 in
Ant walks=d=2r=2×15=30
difference=47.1-30=17.1 in

Which function has a negative discriminant value? On a coordinate plane, a parabola opens up. It goes through (negative 3, 0), has a vertex at (1, negative 16), and goes through (5, 0). On a coordinate plane, a parabola opens up. It goes through (negative 3, 5), has a vertex at (negative 1.5, 2.75), and goes through (0, 5). On a coordinate plane, a parabola opens down. It goes through (negative 2, 0), has a vertex at (0, 4), and goes through (2, 0). On a coordinate plane, a parabola opens down. It goes through (negative 1, negative 4), has a vertex at (3, 0), and goes through (5, negative 4).
Answer: On a coordinate plane, a parabola opens up. It goes through (negative 3, 5), has a vertex at (negative 1.5, 2.75), and goes through (0, 5).

Joshua uses his thermometer and finds the boiling point of ethyl alcohol to be 75 degrees Celsius. He looks in a reference book and finds that the actual boiling point of ethyl alcohol is 80 degrees Celsius. What is his percent error?
Answer:
6.25%
Step-by-step explanation:
75 - 80 = -5
Absolute value of -5 is positive so -5 = 5
5 ÷ 80 = 0.0625 (1/16)
0.0625 × 100 = 6.25%
Joshua's percent error is 6.25%
Point M divides AB such that AM:MB = 1:4. If A has coordinates (-4, 3) and B has coordinates (6, 8). What are the coordinates of M?
Answer:
Coordinates of M = [tex]\left ( -2,4 \right )[/tex]
Step-by-step explanation:
Given: AM:MB = 1:4, A has coordinates (-4, 3) and B has coordinates (6, 8)
To find: coordinates of M
Solution:
According to section formula, if M(x, y) divides line joining points [tex]A(x_1,y_1)\,,\,B(x_2,y_2)[/tex] in ratio [tex]m:n[/tex] then coordinates of point M are [tex]\left ( \frac{mx_2+nx_1}{m+n},\frac{my_2+ny_1}{m+n} \right )[/tex]
Put [tex]A(x_1,y_1)=(-4,3)\,,\,B(x_2,y_2)=(6,8)\,,\,m:n=1:4[/tex]
Therefore,
[tex](x,y)=\left ( \frac{6-16}{1+4},\frac{8+12}{1+4} \right )=\left ( -2,4 \right )[/tex]

He drives the same number of miles each day.
How many miles does he drive in 1 day?
What is the slope of the line containing (-1,8) and (3, -12)?
Answer:
-5
Step-by-step explanation:
We can find the slope since we have two points
m = (y2-y1)/(x2-x1)
= (-12-8)/(3 - -1)
= (-12-8)/(3+1)
= -20/4
= -5
Answer:
-5
Step-by-step explanation:We can find the slope since we have two points
m = (y2-y1)/(x2-x1)
= (-12-8)/(3 - -1)
= (-12-8)/(3+1)
= -20/4
= -5

First make 112% into a decimal, now its 1.12, add all the scooters' sales from all years and multiply by 1.12 then add that number to the total sales of the scooters
Answer:
725 + 579 + 696 = 2000 (What a coincidence)
112% = 112 / 100 = 1.12
Multiply the increase
2000 x 1.12 = 2240
2240 is the amount of scooters sold.

How does the graph show that the rate of change is constant?
A graph has a constant rate of change when the graph is linear and portrays a straight line. The slope will remain constant which forms the straight line in the graph.
Answer:
Because it is a straight line
Step-by-step explanation:
If it changed there would be curves, points, corners, zig zags, since this is straight, that means the R.O.C commonly known as slope, is not changing

For it to be scalene, all 3 sides must be of different length, so cross off D. Acute means all angles are less then 90°, so cross off the top 2.
A motorboat travels 50 miles downstream in a river, then turns around and travels back to its starting point. The total trip takes 8 hours. The rate of the current in the river is 2miles per hour. Remembering that distance = rate x time, what is the rate of the motorboat in calm water? HELP NEEDED ASAP
A. 0.31 miles per hour
B. 2.08 miles per hour
C. 12.5 miles per hour
D. 12.8 miles per hour
Answer:
The speed of the boat in calm water is 12.8 miles per hour.
Step-by-step explanation:
While going downstream the speed of the boat is "x + 2", where x is the speed in calm water, while going upstream the speed of the boat is "x - 2". He made a trip that had two legs, each with a distance of 50 miles, therefore, the sum of the times it took him to complete each leg must be equal to the total time of the trip.
[tex]speed = \frac{distance}{time}\\\\time = \frac{distance}{speed}[/tex]
For the upstream:
[tex]time_{up} = \frac{50}{x - 2}[/tex]
For the downstream:
[tex]time_{d} = \frac{50}{x + 2}[/tex]
The sum of each of these times must be equal to "8 h", therefore:
[tex]8 = time_{up} + time_{d}\\\\8 = \frac{50}{x - 2} + \frac{50}{x + 2}\\\\8 = \frac{50*(x+2) + 50*(x - 2)}{(x-2)*(x+2)}\\\\8*(x-2)*(x+2) = 50*x + 100 + 50*x - 100\\\\8*(x^2 - 4) = 100*x\\\\8*x^2 - 100*x - 32 = 0\\\\x^2 - 12.5*x - 4 = 0\\\\x_{1,2} = \frac{-(-12.5) \pm \sqrt{(-12.5)^2 - 4*(1)*(-4)}}{2}\\\\x_{1,2} = \frac{12.5 \pm \sqrt{156.25 + 16}}{2}\\\\x_{1,2} = \frac{12.5 \pm \sqrt{172.25}}{2}\\\\x_{1,2} = \frac{12.5 \pm 13.124}{2}\\\\x_1 = 12.812\\\\x_2 = -0.312[/tex]
Since the speed can't be negative in this context, the only possible answer is 12.812 mph.

A sector of a circle whose radius is 4 centimeters, has a central angle of 30 Which of the following. which of following represents the area of this sector in square centimeters?
(1). 12π/5
(2). 8π/15
(3). 4π/3
(4). 6π/5
Answer:
area of the sector =4π/3 cm²
Step-by-step explanation:
To find the area of the sector, we will follow the steps below;
first write the formula for finding area of a sector
area of a sector = Ф/360 × πr²
where r is the radius
from the question given
Ф= 30 and radius = 4 centimeters
we can proceed to insert the values into he formula above
area of a sector = Ф/360 × πr²
=30/360 ×π×4²
=1/12 ×π×16
=16π /12
=8π/6
=4π/3
area of the sector =4π/3 cm²

A. 1/2
B. 2
C. 1
D. -2
Is the C
Because 3+(-1) = 2
2:2= 1
Answer:
C
Step-by-step explanation:
A. 180
B.82
C. 46
D. 98
Please answer help me
Answer:
D
Step-by-step explanation:
Because the angle with measure 82 and angle 1 are corresponding angles, their angles measure must be equal, and therefore angle 1 has measure of 82 as well. Since angles 1 and 2 are a linear pair, they must be supplementary, and angle 2 is therefore 180-82=98 degrees. Hope this helps!
[tex]answer = 98 °\\ solution \\ < 1 = 82(being \: corresponding \: angless) \\ < 1 + < 2 = 180(sum \: of \: angle \: in \: straight \: line) \\ or \: 82 + < 2 = 180 \\ or < 2 = 180 - 82 \\ < 2 = 98° \\ hope \: it \: helps \\ good \: luck \: on \: your \: assignment[/tex]
A fair spinner A is spun 7 times. What is the probability of getting “Green” at least 5 times if there are 8 colors separated equally?
Answer:
[tex]6\frac{2}{3}[/tex]
Step-by-step explanation:
OK, so basically I'm pretty sure that you add all of them together and put it as a fraction over 3 so basically [tex]\frac{20}{3}[/tex] then simplify it into [tex]6\frac{2}{3}[/tex]

Za and Zb are complementary angles. Za measures 22º.
What is the measure of Zb?
Answer:
b = 68
Step-by-step explanation:
Complementary angles add to 90 degrees
a+b = 90
22+b = 90
Subtract 22 from each side
b = 90-22
b = 68
Answer:
68 degrees
Step-by-step explanation:
Complementary Angles: The sum of the angles is 90 degrees.
If angle a is 22 degrees, then...
a + b = 90
22 + b = 90
22 - 22 + b = 90 - 22
b = 68
That means that the measure of angle b is 68 degrees.
I hope this helps! Have a great day!

PLZZ HELPP Why is it important to simplify rational expressions before multiplying or dividing? How do you determine that a rational expression is in simplest form? Compare the process to addition and subtraction.
Answer:
"Simplifying rational expressions will make the further calculations easier since the variables to work with will usually be smaller.
To determine that a rational expression is in simplest form we need to make sure that the numerator and the denominator have no common variables."
