Answer:
b= 11
c= 121
Step-by-step explanation:
equation for b-
48 = 4x + 4
48-4 = 44
44 / 4 = 11
11 = b
and then for c
48 + 11 = 59
180 - 59 = 121
you use 180 as the number to subtract from because thats how many degrees are in a triangle
2x - 3y <= 9
2x + 3y <= 3
Step-by-step explanation:
2x - 3y = 9
2x + 3y = 3
__________ -
-6y = 6
y = -1
2x - 3y = 9
2x - 3(-1) = 9
2x - (-3) = 9
2x = 12
x = 6
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.

can yall do the work of the answer 95 to this
9514 1404 393
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°

A pet store donated 50 pounds of food for adult dogs, puppies, and cats to an animal shelter. 17 3 4 pounds was adult dog food and 17 7 8 pounds was puppy food. How many pounds of cat food did the pet store donate?
Answer:
14 3/8 pounds
Step-by-step explanation:
Given
Total pounds donated = 50 pounds
Amount for dogs D = 17 3/4 pounds
Amount for puppy P = 17 7/8 pounds
Required
Amount of cat food C
Total = D + P + C
50 = 17 3/4 + 17 7/8 + C
50 = 71/4 + 143/8 + C
50 = (142+143)/8 + C
50 = 285/8 + C
C = 50 - 285/8
C = 400-285/8
C = 115/8
C = 14 3/8
Hence the pounds of cat food donated was 14 3/8 pounds
Explain the step to covert between measurements for example convert 6.5 miles to yard 11,440 yards by going into calculator and selecting those two measurements you need to calculate
9514 1404 393
Explanation:
Any units conversion is simply multiplication by the value 1 written in a special form. That form is a fraction with the new unit in the numerator and the old unit in the denominator. The numbers in the numerator and denominator are the numbers that make the value of the fraction be 1. That is, the numerator and denominator are equal.
Here, we know that 1 mile = 1760 yards. The new unit is yards, and the old unit is miles, so the conversion fraction we want is (1760 yards)/(1 mile). Then the conversion looks like this:
[tex](6.5\text{ mi})\dfrac{1760\text{ yd}}{1\text{ mi}}=(6.5\times1760)\text{ yd}=11{,}440\text{ yd}[/tex]
You will notice that the units "mi" in numerator and denominator cancel, leaving only the units "yd".

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.
