Answer:
? = 95°
Step-by-step explanation:
Long arc QR is twice the measure of inscribed angle QSR, so is 2×95° = 190°. That, together with the remaining short arcs ? and RS will make up the total circle of 360°.
arc QR + arc RS + ? = 360°
190° +75° +? = 360°
? = 360° -265° . . . . . . subtract 265° from both sides
? = 95°

Forces affect motions in living and nonliving things. In a human, swallowed food moves down the esophagus into the stomach, even if the human is upside down doing a handstand. Which force moves food through the esophagus into the stomach?
a:Frictional force in the esophagus moves food through the esophagus.
b:Gravitational force pulls food through the esophagus.
c:Magnetic force in the stomach pulls food through the esophagus into the stomach.
d:Push force from contractions of the esophagus moves food through the esophagus.
Answer:
a
Step-by-step explanation:
The force that moves food through the esophagus into the stomach is;
d:Push force from contractions of the esophagus moves food through the esophagus.
When we are sitting upright and eat food, the food moves down the esophagus and into the stomach.
Now, that will be a logical explanation because just like a flow, it goes with gravity position and would go from up down like a free fall.
However, when we are not sitting upright but upside down with our head on the ground and legs up, what happens is that the food still goes to the stomach via the oesophagus but this time because of the position of the body, the oesophagus will contract i.e. contraction in the walls of the food pipe which will lead to a push force that takes the food into the stomach.

You are an office manager. You have been asked to research the cost of an online messaging service. The service charges $3.25 per employee each month. However, if you sign up for a full one-year subscription, the charge drops to $2.80 per employee per month. Your office has 20 employees.
Answer:
The final cost for the service that offers the better deal is $56 per month, in total for the whole year it's $672.
The cost for the one that offers the worse deal is $65 per month.
Step-by-step explanation:
All we need to do is multiply the amount of money by the number of employees.
So:
20 × $2.80 = $56
(Calculations for worse deal)
20 × $3.25 = $65
Answer: $108.00
Step-by-step explanation:
$3.25 per employee, per month (3.25 x 20 x 12) = $780/ mo
$2.80 per employee, per month (2.80 x 20 x 12) = $672/mo
subtract the two, which equals $108.00 will be saved each year with the one-year subscription.

You prepare 10 scoops of dog food for 5 dogs, and prepare 16 scoops of dog food for 8 dogs. What
is the constant of proportionality for the amount of dog food to the number of dogs? How many
scoops of dog food should you prepare for 6 dogs?
Answer:
12 scoops of dog food are needed for 6 dogs,
Step-by-step explanation:
Proportions
The number of scoops of dog foods and the number of dogs are proportional variables.
We are given that 10 scoops of dog foods are used for 5 dogs. This gives a proportion of 10/5=2 scoops per dog.
We also know that 16 scoops are used for 8 dogs. The proportion is also 16/8=2 scoops per dog.
Thus, the constant of proportionality is 2.
For 6 dogs, you need to prepare 2*6 = 12 scoops of dog food.
12 scoops of dog food are needed for 6 dogs,

A right circular cylinder is changing shape. The radius is decreasing at the rate of 2 inches/sec while it's height is increasing at the rate of 5 inches/sec. When the radius is 4 inches and the height is 6 inches, how fast is the volume changing? Round your answer to three decimal places
The volume of the right circular cylinder is changing at a rate of approximately 50.265 cubic inches per second.
Given that a right circular cylinder is changing shape.
The radius is decreasing at the rate of 2 inches/sec
dr/dt = -2 inches
The radius is increasing at the rate of 2 inches/sec
dh/dt=5 inches
We have to find dv/dt when r is 4 inches and h is 6 inches.
Volume=πr²h
Differentiate with respect to 't' to find the change of volume:
[tex]\frac{dV}{dt}=\pi(2rh\frac{dr}{dt}+r^2\frac{dh}{dt})[/tex]
Plug in the values:
[tex]\frac{dV}{dt}=3.14(2(4)(-2)(6) + 16(5))[/tex]
[tex]=3.14(-96+80)[/tex]
[tex]=3.14(-16)[/tex]
[tex]=-50.265[/tex] inch³/sec.
Hence, the volume change is -50.265 inch³/sec.

HELP PLEASE ITS Which point would not be a solution to the system of linear inequalities shown below? y -3x+7!
(5,−5)(10,−8)(5,−6)(−10,−7)
Answer:
(-10,-7)
Step-by-step explanation:
Lets start with the equation y>-3x+7
Which of these are solutions?
(5,-5) - yes
(10,-8) - yes
(5,-6) - yes
(-10,-7) - no
Now lets do the equation y<4/5x-2
Which of these are solutions?
(5,-5) - yes
(10,-8) - yes
(5,-6) - yes
(-10,-7) - no
So, the point (-10,-7) is not a solution to the system of equations.
At a store, a hat has a regular price of x dollars. During a sale, the price of the hat is discounted by 20%. The expression 0.8x describes the discounted price, in dollars, of the hat. Which expression also describes the discounted price, in dollars, of the hat?
Answer: D) x - 0.2x
Step-by-step explanation:
The hat has a regular price of x dollars.
This price is reduced by 20% so the relevant expression for the discount is; 20% * x or; 0.2x
The discounted price will be the price of the hat less the discount which means the formula will be;
= Price - discount
= x - 0.2x
what's the slope between (5,-2) and (-7,22)
Answer: The answer is: -2
Step-by-step explanation:
Here, suppose
(5,-2)=(x1, y1)

Now, use the slope equation to find slope(m).
y2-y1=m(x2-x1)
or,m=y2-y1/x2-x1

How do geologists believe that the Devils Tower was formed?
A. All the land except the rocks around the Devils Tower were
eroded during the Ice Age.
B. The Devils Tower was an ancient hotspot that plate movements
isolated after the volcano became inactive.
C. Magma pushed up from the mantle to sedimentary rocks which
then eroded leaving the column.
D. It's the stem of a volcano that erupted millions of years ago
and surrounding rock eroded away.
Answer:
C. Magma pushed up from the mantle to sedimentary rocks which
then eroded leaving the column.
Step-by-step explanation:
Geologists Carpenter and Russell studied Devils Tower in the late 1800s and concluded that the Tower was formed by an igneous intrusion (the forcible entry of magma through other rock layers).

A map has the scale 0.75 of an inch equals 220 miles. The distance from Springfield to Glenview is 6 inches. How many actual miles separate Springfield from Glenview?
Answer:
1,760 actual miles separate Springfield from Glenview.
Step-by-step explanation:
Scaling
Objects can be represented in a reduced or augmented size by using scaling which is basically multiplying or dividing real dimensions by a constant factor. We use scaling when representing geographic locations on a map.
The map has the scale:
0.75 inch => 220 miles
This gives us the scaling factor as 220/0.75. There is no need to divide.
We are given the distance from Springfield to Glenview is 6 inches on the map. The actual distance is
6*220/0.75 = 1,760
1,760 actual miles separate Springfield from Glenview.
