Answer:
1899.7 in^3.
Step-by-step explanation:
Radius = 1/2 diameter
= 22 * 1/2 = 11.
Volume = 1/3 pi r^2 h, so
= 1/3 * 3.14 *1 1^2 *1 5
= 1899.7 in^3.
A math textbook has a mass that is 400 grams greater
than a science textbook. If the science textbook has a
mass of 2 kilograms, what is the mass of the math
textbook, in kilograms?
Answer:
0.8
Step-by-step explanation:
because 400g = 0.4kg
and 0.4kg x 2 = 0.8

How many ounces of a 19% alcohol solution and a 37% alcohol solution must be combined to obtain 90 ounces of a 24% solution
Answer:
19% alcohol solution = 65 ounces
37% alcohol solution = 25 ounces
Step-by-step explanation:
Let
19% alcohol solution = x
37% alcohol solution = y
x + y = 90 (1)
0.19x + 0.37y = 90*0.24
0.19x + 0.37y = 21.60 (2)
from (1)
x = 90 - y
Substitute into (2)
0.19x + 0.37y = 21.60
0.19(90-y) + 0.37y = 21.60
17.1 - 0.19y + 0.37y = 21.60
- 0.19y + 0.37y = 21.60 - 17.1
0.18y = 4.5
y = 4.5/0.18
y = 25 ounces
x + y = 90 (1)
x + 25 = 90
x = 90 - 25
x = 65 ounces

Answer:
A.16.5 if that’s incorrect try b.33
Step-by-step explanation:
The formula is: A = B * H where B is the base, H is the height, and * means multiply.
it may be wrong I’m not sure but 30 * 11 is 330 divded by 2 is 16.5

Mr. Sloan leaves his house at 8:30. It takes 50 minutes to get to Boston airport. There were a 45 minute delay. It will take 5 hour and 10 minutes for the trip to Salt lake. What time will Mr. Sloan arrive in Salt Lake
Answer:
15:15
Step-by-step explanation:
The time he would get to salt lake is the sum of all the times
8: 30 + 45 min + 50 min + 5:10
to find the time, add only the minutes : 30 + 45 + 50 + 10 = 135 minutes
Remember 60 mins = 1 hour
so 135 mins = 2 hours 15 minutes
Now add the hours
8 + 5 = 13 hours
13 hours + 2 hours 15 minutes = 15:15

Step-by-step explanation:
The equation simplifies to [tex]\frac{5}{6} x + 4 = x + 2[/tex]. This can further simplify to [tex]-\frac{1}{6}x = -2[/tex]. Divide both sides by [tex]-\frac{1}{6}[/tex] to get [tex]x = 12[/tex].

Charlie watched 1 3 of a movie in the morning, and he watched some more at night. By the end of the day, he still had 2 5 of the movie left to watch. How much of the movie did Charlie watch at night?
Answer: 4/15 of the movie
Step-by-step explanation:
In the morning, Charlie watched ¹/₃ of a movie. He then watched some more at night.
At the end of the day, he still had ²/₅ of the movie to watch.
The proportions of an item must always add up to one. This means that if you added the 1/3 to the 2/5 and then to the fraction Charlie watch at night, they should add up to one.
¹/₃ + ²/₅ + x = 1
x = 1 - ¹/₃ - ²/₅
[tex]x = \frac{15 - 5 - 6 }{15} \\\\x = \frac{4}{15}[/tex]

Verify that f and g are inverses functions using composition , show your steps
Answer: We can conclude that f(x) and g(x) are not inverses.
Step-by-step explanation:
If we have two functions:
f(x) and g(x)
These functions are inverses if:
f( g(x) ) = x
g( f(x) ) = x
In this case, we have:
f(x) = 12*x - 12
g(x) = (1/12)*x - 1
Now we need to check the compositions:
f( g(x) ) = 12*g(x) - 12 = 12*( (1/12)*x - 1) - 12 = (x - 12) - 12 = x - 24
and:
g( f(x)) = (1/12)*f(x) - 1 = (1/12)*(12*x - 12) - 1 = 12*x/12 - 12/12 - 1 = x - 1 - 1 = x - 2
In both cases, we can see that:
f( g(x) ) ≠ x
and:
g( f(x) ) ≠ x
Then we can conclude that f(x) and g(x) are not inverses functions.

Answer:
144x^22y^16
Step-by-step explanation:
Here, thankyou!!!!!!!
Answer:
Perimeter of i - 22CM
Area of i - 13CM^2
Perimeter of ii -38CM
Area of ii -66CM^2
Perimeter of iii -30CM
Area of iii- 42CM^2
Perimeter of iv - 50CM
Area of iv- 126CM^2
Step-by-step explanation:
SHAPE I:
PERIMETER = S + S + S + S + S +S
= 7 + 1 + 5 +3 +4 +2
= 22CM
AREA = Part a - 4 * 2 = 8cm^2 part B - 5 *1 = 5cm^2
Total = 8 + 5 = 13cm^2
SHAPE II:
PERIMETER = S + S + S + S + S +S
= 4 + 4 +5 + 6 + 9 + 10
= 38 CM
AREA = Part a - 5 * 10 = 50 cm^2 part B - 4 *4 =16 cm^2
Total = 50+16 =66 cm^2
SHAPE III:
PERIMETER = S + S + S + S + S +S
= 9 + 2 + 3 + 4 + 6 + 6
= 30CM
AREA = Part a - 6 * 6 = 42cm^2 part B - 3 * 2= 6cm^2
Total = 36 + 6 =42 cm^2
SHAPE IV:
PERIMETER = S + S + S + S + S +S
= 9 + 10 + 4 + 6 + 6 + 15
= 50 CM
AREA = Part a -15 * 6 = 90 cm^2 part B - 9 *4 = 36cm^2
Total = 90 + 36 = 126cm^2

How do you do 20/4 divided by 8/9 and put it in simplest form?
Answer:
45/8, or 5.625
Step-by-step explanation:
20/4 is simplified to 5/1.
5/1 divided by 8/9
5/1 * 9/8
45/8
simplified to 5.625
Answer:
45/8 or 5 5/6.
Step-by-step explanation:
20/4 / 8/9 We invert the second fraction and multiply:
= 20/4 * 9/8
= 180 / 32
= 45/8
= 5 5/8.
Cory went to Kohl's and bought 10 pairs of socks for $2.50 each and 3 pairs of shoes for d dollars each. He spent a total of $135.97. Write an equation to find the cost of one pair of shoes.
Answer:
[tex]25+3d=135.97[/tex]
Step-by-step explanation:
Number of pairs of socks = 10
Cost of each pair of socks = $2.50
Cost of 10 pairs of socks = 10 × 2.50 = $25
Number of pairs of shoes = 3
Cost of each pair of shoes = $d
Cost of d pair of shoes = $3d
Therefore,
[tex]25+3d=135.97[/tex]
So,
Equation is [tex]25+3d=135.97[/tex]

The simplified expression 1/3 * 1/3 * 1/3 as exponents is 1/3³
How to simplify the expression as exponentsFrom the question, we have the following parameters that can be used in our computation:
1/3 * 1/3 * 1/3
Express as equation
Result = 1/3 * 1/3 * 1/3
Apply the law of indices
So, we have the following representation
1/3 * 1/3 * 1/3 = 1/3¹⁺¹⁺¹
Evaluate the sum
1/3 * 1/3 * 1/3 = 1/3³
Using the above as a guide, we have the following:
The expression cannot be further simplified
Hence, the simplified expression is 1/3³

Corresponding angles (angles on the same spot in the transversal) are equal to each other. For example angle 2 will be equal to angle 6.
Rotate the given figure about the origin using the given angle.
Answer:
P’(-5,2)
J’(0,3)
