Answer:
32
Step-by-step explanation:
There are two ways of doing this.
Frist, divide the amount of bolts by time. This will get you the bolts produced in 1 minute.
195/20
=
9.75
Now we know that 9.75 bolts are produced every 1 minute.
Lets divide the 312 bolts by the bolts produced per minute. This will give us the amount of minutes it takes to produce the 312 bolts.
312/9.75
=
32.
This is our answer.
Another way of doing thisis to divide the 20 minutes by 195, this will give you how long it takes to produce a single bolt.
20/195
=
0.1025
Now, just multpliy it by 312, and you get how long it takes to produce 312 bolts.
0.1025*312
=
32
And again, you get the answer.
Hope this helps! ;)

A ladder 10 ft long rests against a vertical wall. If the bottom of the ladder slides away from the wall at a rate of 3 2 ft/s, how fast is the angle between the ladder and the ground changing when the bottom of the ladder is 8 ft from the wall
Answer:
dα/dt = - 0,25 rad/sec
Step-by-step explanation:
The vertical wall, the ground from the vertical wall up to the ladder, and the ladder shape a right triangle. angle α will be the angle between the ladder and the ground, then:
cos α = distance between the wall and the down end of the ladder (x) / length of the ladder
cos α = x/ L
- sin α * dα/dt = dx/dt * L /L²
- sin α * dα/dt = dx/dt /L
When the down end of the ladder is 8 ft apart from the wall
cos α = 8 / 10 = 0,8 then cos² α + sin²α = 1
sin² α = 1 - cos²α sin²α = 1 - (0.8)² sin²α = 0.36
sin α = 0.6
dα/dt = ?
dx/ dt = 3/2
L = 10 ft
x = 8 ft
By substitution
- 0.6*dα / dt = (3/2) / 10
dα/dt = - 1.5 / 6
dα/dt = - 0,25 rad/sec
(-) means the angle is decreasing

A researcher started tracking the number of mice in the lab.
Which of the following equations models how many mice
there will be in the lab after 10 months?
Answer:
1536 rats will be total after 10 months
Step-by-step explanation:
The number is multiplied by 2 each time, so we have to continue multiplying by 2
Month 5: 48 x 2 = 96
Month 6: 96 x 2 = 192
Month 7: 192 x 2 = 384
Month 8: 384 x 2 = 768
Month 9: 768 x 2 = 1536

The area of a rectangle is 20 square units and its length is 5 centimeters. Find its perimeter
Answer:
18 centimeters.
Step-by-step explanation:
Since you already know the length (height) divide 20 by 5 = 4.
This gives you the width (4), add up all the sides ( 4 + 4 + 5 + 5).
The sum comes out to be 18.

X=
Help
Answer:
x = 13
Step-by-step explanation:
Since this is a right triangle, we can use the Pythagorean theorem
a^2 + b^2 = c^2 where a and b are the legs and c is the hypotenuse
5^2 + 12^2 = x^2
25+144 = x^2
169 = x^2
Taking the square root of each side
sqrt(169) = sqrt(x^2)
13 =x
Answer:
13
Step-by-step explanation:
[tex] \sqrt{5^{2} + 12^{2}} = \sqrt{169} \\ \\ \sqrt{169} = 13[/tex]

3x+9y=12
-3x-6y=18
Solve the system by using elimination
Answer: (x, y) = (-26, 10)
This means x = -26 and y = 10 pair up together
===============================================================
How to get that answer:
Add the equations straight down. Think of having 3 separate columns for the three different like terms.
3x + (-3x) becomes 0x and that's just 0. So the x terms go away9y + (-6y) is the same as 9y-6y which turns into 3y12 + 18 becomes 30After all that, we're left with the simpler equation 3y = 30. That solves to y = 10 after dividing both sides by 3.
Plug this back into any equation involving x and y. Solve for x
3x+9y = 12
3x+9(10) = 12
3x+90 = 12
3x = 12-90
3x = -78
x = -78/3
x = -26
We have found that x = -26 and y = 10 pair up together to form the solution.
-------------------
Checking the answer:
Plug (x,y) = (-26, 10) into the first equation
3x+9y = 12
3(-26)+9(10) = 12
-78+90 = 12
12 = 12
We get a true equation since the same thing is on both sides.
Repeat the same idea for the second equation
-3x-6y = 18
-3(-26) - 6(10) = 18
78 - 60 = 18
18 = 18
The second equation is true as well.
Both equations are true, so the solution (x, y) = (-26, 10) is confirmed.
Answer:
-26, 10

See the steps below:)

Beth can buy T-shirts in packs of 5 for $5.55 or in packs of 2 for $4.82. How much money does she save by buying 40 T-shirts at a better price?
Answer:
$52
Step-by-step explanation:
Given data
Beth can buy T-shirts in packs of 5 for $5.55
Cost per shirt
=5.55/5
=$1.11
To buy 40 shirt
=1.11*40
=$44.4
In packs of 2 for $4.82
cost per shirt
=4.82/2
=$2.41
To buy 40 shirt
=2.41*40
=$96.4
Hence the best buy in packs of 5 for $5.55
and the cost per shirt is $1.11
He will save
=96.4-44.4
=$52

What is the missing angle measure?
Answer:
x = 33
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
Subtract the sum of the 2 angles from 180 for x
x = 180 - (90 + 57) = 180 - 147 = 33

If you roll the die 60 times, how many twos can you expect to roll?
Answer:
10
Step-by-step explanation:
Rolling a single six-sided die, you would get two 1/6th of the time because there is one two out of the six sides.
So 60 rolls would be 60*(1/6)=60/6=10

Answer: Choice C) 17 degrees
=============================================================
Work Shown:
Apply the law of cosines
c^2 = a^2 + b^2 - 2*a*b*cos(C)
12^2 = 28^2 + 18^2 - 2*28*18*cos(C)
144 = 1108 - 1008cos(C)
144+1008cos(C) = 1108
1008cos(C) = 1108-144
1008cos(C) = 964
cos(C) = 964/1008
C = arccos(964/1008)
C = 16.991286936969 which is approximate
C = 17 degrees
Note: arccos is the same as inverse cosine.
