Answer: The area is 19.625 cm^2
Step-by-step explanation:
For the area of a circle, the equation is:
A = pi*r^2
where pi = 3.14 and r is the radius of the circle, and the radius is half the diameter.
We have that the diameter is 5 cm, then the radius is:
r = 5cm/2 = 2.5 cm
Then the area is
A = 3.14*(2.5cm)^2 = 19.625 cm^2
Answer:
[tex]19.63 cm^2[/tex]
Step-by-step explanation:
Diameter of the Cross-Sectional Area=5 cm
Radius =Diameter/2
Therefore, Radius of the Cross-Sectional Area of the Cylindrical Pipe =5/2=2.5cm.
[tex]\text{Area of a circle, A=} \pi r^2\\=3.14*2.5^2\\=19.625\\$Area of the circle \approx 19.63 cm^2 $ (to the nearest millimeter)[/tex]
The Cross-Sectional Area of the cylindrical pipe is [tex]19.63 cm^2[/tex].

Hope this helps!
Answer: $36.03
Step-by-step explanation: 25% of $45 is $11.25, and 45-11.25 is 33.75. The sales tax is $2.28, and that plus $33.75 is $36.03.
A full jar of honey weighs 750 grams, and the same jar two-thirds
full weighs 550 grams. What is the weight of the empty jar in grams
Answer:
150 grams
Step-by-step explanation:
The weight of the full jar of honey is equivalent to x + y, where x is equal to the weight of honey and y is equal to the weight of the jar.
x+y = 750
2x/3+y = 550
You can solve for y in the first equation and get:
y = 750-x
Plug that in to the second equation and you get:
-x/3+750 = 550
Subtract 750 from both sides:
-x/3 = -200
Multiple -3 on both sides:
x = 600 grams
The weight of the jar is 750-600 or 150

Mrs Lopez drives a number of miles north. Then she drives 34 miles west. She drives 94 miles in all. Complete the number sentences to show how many miles she drives north.
? +_ = _ and _ - _ = ?
Answer:
60
Step-by-step explanation:
number of miles driven north plus 34 equal 94.
subtract 94 from 34 to get your answer.
Mrs. Lopez drives 60 miles north.
The completed number sentences are:
60 + 34 = 94 and 94 - 34 = 60.
What is number sentence?Let's assume Mrs. Lopez drives x miles north.
The number sentence for the total distance she drives can be written as:
x + 34 = 94
This equation represents the sum of the distance she drives north (x) and the distance she drives west (34), which equals the total distance she drives (94).
To find the value of x, subtract 34 from both sides of the equation:
x = 94 - 34
Simplifying the expression, we have:
x = 60
Therefore, Mrs. Lopez drives 60 miles north.
The completed number sentences are:
60 + 34 = 94 and 94 - 34 = 60.

Cedric has 200 songs on his Apple Music account. Of these songs, 24 are Indie songs. What percent of Cedric's songs are Indie songs?
Answer:
12%
Step-by-step explanation:
First put it into a fraction 24/200
Half it to make it to 100%
12/100=100%
Final answer:
To find the percentage of Cedric's songs that are Indie songs, divide the number of Indie songs by the total number of songs and multiply by 100%. The percentage of Indie songs is 12%.
Explanation:
To find the percentage of Cedric's songs that are Indie songs, we need to divide the number of Indie songs by the total number of songs and then multiply by 100.
So, the percentage of Indie songs is calculated as:
Percentage of Indie songs = (Number of Indie songs / Total number of songs) * 100% = (24 / 200) * 100% = 12%.

1. Compare subtracting 10/8 - 4/8 to subtracting 10-4. How are they alike? How
are they different?
The subtraction of 10/8 - 4/8 is similar to 10-4 only in the general subtraction process, but they differ in the types of numbers used (fractions vs. whole numbers) and the results generated (a fraction vs. a whole number).
Explanation:The process of subtracting 10/8 - 4/8 is similar to subtracting 10-4 because in both cases, you are subtracting one number from another (~subtraction process~). However, they are different in terms of the kind of numbers used for subtraction. In the first operation, we are subtracting fractions while in the second operation, we are subtracting whole numbers.
To elaborate, in 10/8 - 4/8, they have the same denominators (8), so it's straightforward to subtract the numerators (numbers on top of the fraction): 10 - 4 = 6. So, the result is 6/8, which simplifies to 3/4.
In 10 - 4, the operation is simpler because we are working with whole numbers. By subtracting 4 from 10, we get 6 as the result. So, the results of the operations bear another difference, one yields a fraction, the other yields a whole number.

cupcakes in the Grande box are chocolate. What does she mean by that? How
many chocolate cupcakes will that be?

Answer:
If the ratio of chocolate to vanilla cupcakes is the same, that would make there 12 chocolate and 12 vanilla cupcakes. She means that she can use equivalent ratios by, lets say the grande box had 100 cupcakes, then we know 50 are chocolate. We don't know how many chocolate cupcakes that will be because we don't know how much bigger the bigger box of cupcakes is.

T.J.
$58
$48
$40
$42
$42
Answer:
Justin has a lower mean tip for the week with $42.
Step-by-step explanation:
To find the mean you must add all the numbers and then divide the sum by how many numbers there are.
For Justin you must add 32 + 45 + 50 + 33 + 50 then you'll get the sum 210. There are 5 numbers so you divide 210 by 5 which gives you the quotient 42.
As for T.J. you add 58 + 48 + 40 + 42 + 42 which gives you the sum of 230. Then you divide 230 by 5 since there's 5 numbers. Now you have the quotient of 46.
46 is greater than 42 so Justin has the lower mean.
Answer:
Justin by 4
Step-by-step explanation:
you add all the numbers for T.J. and for Justin separately and divide by five. you get 42 for Justin and 46 for T.J.

-20a -8 + 12b is ? what is the answer?
Answer:
4(-5a + 3b - 2)
Step-by-step explanation:
Aside from changing the order of the terms so that the "a" term comes first and the "b" term second, there's nothing you can do with this expression -20a -8 + 12b. But notice that 4 is a factor common to all three terms, and therefore it can be factored out:
Rearranging the terms, we get
-20a + 12b - 8 = 4(-5a + 3b - 2)
Answer:
The answer is -4(5a+2-3b)
