What is the slope of the line y=3
Answer:
slope = 0
Step-by-step explanation:
recall that the equation of a line can be expressed as:
y = mx + b, where m is the slope and b is the y-intercept.
in our case we are given y = 3
which can be re-written:
y = (0)x + 3
if we compare this with the general equation above, we can see that
slope = m = 0
Answer: the slope is zero
Step-by-step explanation:
The equation of line in slope - intercept form is given as : y = mx + c , where m is the slope and c is the y - intercept. This means that the line y = 3 is a horizontal line that passes through the point y = 3 , therefore , the slope is zero

Simplify this expression.
1 + 4.25n + 32p – 3 + (–2p) + 54n
A. 5.5n – 12p – 2
B. 9.5n + 1.5p – 2
C. 94n − 1.5p − 4
D. 3.75n – p + 1
After combining like terms, the expression simplifies to 58.25n + 30p - 2, which does not match any of the provided answer choices, indicating an error in the options given.
Explanation:To simplify the expression 1 + 4.25n + 32p
dash; 3 + (
minus;
2p) + 54n, we combine like terms. Let's first combine the constant terms (1 and -3), the 'n' terms (4.25n and 54n), and the 'p' terms (32p and -2p).
First, we handle the constants: 1 - 3 = -2
Now, combine the 'n' terms: 4.25n + 54n = 58.25n
Then, combine the 'p' terms: 32p - 2p = 30p
The simplified expression is 58.25n + 30p - 2, which matches none of the given options (A, B, C, D). There appears to be an error since the proper simplification does not align with the options provided.
In the given case, the correct answer is B. 9.5n + 1.5p - 2 which is the simplified expression.
The correct distribution should be:
[tex]\(1.5 \times 39n = 58.5n\) (which is correct)[/tex]
[tex]\(1.5 \times 20p = 30p\) (which is correct)[/tex]
So the correct simplified expression is:
58.5n + 30p - 2
Now, let's convert the decimals to fractions to match the format of the options provided:
[tex]\(58.5n = 58\frac{1}{2}n = 58n + \frac{1}{2}n = 58n + 0.5n\)[/tex]
30p = 30p
So the expression becomes:
58n + 0.5n + 30p - 2
Therefore, the final simplified expression is:
9.5n + 30p - 2
However, we must correct the coefficient of p to match the format of the options. Since 30p is actually [tex]\(1.5 \times 20p\)[/tex] , we should have:
1.5p = 30p
Thus, the correct final simplified expression is:
9.5n + 1.5p - 2

Make an algebraic equation out if this word problem: Sharkira went bowling with her friends. She paid 3 to rent shoes and then $4.75 for each game of bowling. If she spent a total of $21, then how many games did Shakira bowl?
Shakira played 3 full games because rounding off to 4 would increase the total.
Step-by-step explanation:
Given,
Rent of shoes = $3
Amount paid for each game = $4.75
Total paid by Shakira = $21
Let,
x be the number of games played by Shakira.
Amount paid for each game * Number of games + Rent of shoes = Total paid
[tex]4.75x+3=21\\4.75x=21-3\\4.75x=18[/tex]
Dividing both sides by 4.75
[tex]\frac{4.75x}{4.75}=\frac{18}{4.75}\\x=3.8[/tex]
Therefore,
Shakira played 3 full games because rounding off to 4 would increase the total.

if file that is 274 megabytes is being downloaded if the download is 16.4% complete how many megabytes have been downloaded round to the nearest tenth
44.9 megabytes of download is complete
Solution:
Given that,
File that is 274 megabytes is being downloaded if the download
Therefore, total megabytes of file = 274 megabytes
The download is 16.4% complete
To find: Megabytes that has been downloaded
So, we can say, 16.4 % of total megabytes of file is downloaded
Megabytes that has been downloaded = 16.4 % of total megabytes of file
Megabytes that has been downloaded = 16.4 % of 274
[tex]\rightarrow 16.4 \% \text{ of } 274\\\\\rightarrow 16.4 \% \times 274\\\\\rightarrow \frac{16.4}{100} \times 274\\\\\rightarrow 0.164 \times 274 = 44.936 \approx 44.9[/tex]
Thus 44.9 megabytes of download is complete
Final answer:
multiply 274 megabytes by 0.164, which gives 44.936 megabytes. Rounded to the nearest tenth, this is 44.9 megabytes.
Explanation:
To calculate how many megabytes have been downloaded when 16.4% of a 274 megabyte file has been completed, you simply multiply the total file size by the percentage that has been downloaded. You can convert the percentage into a decimal by dividing it by 100.
So, 16.4% as a decimal is 0.164. Now, multiply the file size by this decimal:
274 megabytes * 0.164 = 44.936 megabytes
Round to the nearest tenth, the amount downloaded is approximately 44.9 megabytes.

on Saturday a bakery sold 6 cakes and several cupcakes a bakery made a total of 165 if Case sell for $12 each and cupcakes sell for $3 each how many cupcakes did they sell
Cakes = x
Cupcakes = y
On Saturday, 6x + y = $165
We are told x = 12, so 6(12) + 3y = 165
72 + 3y = 165
Subtract the entire equation by 72:
3y = 93
Divide by 3 to simplify:
y = 31 cupcakes sold
Find the area of the irregular figure.
Answer:
The area of the irregular figure is 366 cm sq.
Step-by-step explanation:
This irregular figure is made of 1 Rectangle + 1 right Triangle
Area of the Rectangle:
Length of the rectangle = 21 cm,
Width of the rectangle = 14 cm
AREA of Rectangle = LENGTH x WIDTH
= 21 cm x 14 cm = 294 sq cm
⇒Area of the Rectangle = 294 sq cm ..... (1)
Area of the Right Triangle:
Base of the rectangle = 16 cm,
Height of the rectangle = 21 cm - 12 cm = 9 cm
AREA of Right Triangle = [tex]\frac{1}{2} \times B \times H[/tex]
[tex]= \frac{1}{2} \times 16 \times 9 = 72[/tex]
⇒Area of the Right Triangle = 72 sq cm ..... (2)
Now, area of the irregular figure = Area of the( Rectangle +Right Triangle)
= 294 sq cm + 72 sq cm = 366 cm sq
Hence, the area of the irregular figure is 366 cm sq.
Answer:
366 sq. ft
Step-by-step explanation:
First, we have to find the area of the triangle. To do this we have to find the height of the triangle which can be done by subtracting 12 from 21 to get 9. Then we multiply 16 by 9 to get 144 and divide it by 2 to get 72. Now we must find the area of the rectangle. To do this we have to multiply 14 and 21 to get 294. Now we have to add the values together to get 366.

If the perimeter of a triangle is 10x + 12y, and two of the sides are 4x + 14y and 4x − 2y, which is the third side?
A. 2x + 2y
B. 2x
C. 3x + y
D. x + y
Answer:
The third side is
B. [tex]2x[/tex]
Step-by-step explanation:
Given:
Perimeter of triangle = [tex]10x+12y[/tex]
Two sides of the triangle are :
1) [tex]4x+14y[/tex]
2) [tex]4x-2y[/tex]
To find the third side.
Solution:
Let the third side be = [tex]z[/tex]
The perimeter can be given as sum of all 3 sides :
[tex]4x+14y+4x-2y+z[/tex]
Combining like terms.
[tex]4x+4x+14y-2y+z[/tex]
[tex]8x+12y+z[/tex]
The perimeter given = [tex]10x+12y[/tex]
So, we have:
[tex]8x+12y+z=10x+12y[/tex]
Solving for [tex]z[/tex]
Subtracting both sides by [tex]8x[/tex]
[tex]8x-8x+12y+z=10x-8x+12y[/tex]
[tex]12y+z=2x+12y[/tex]
Subtracting both sides by [tex]12y[/tex]
[tex]12y-12y+z=2x+12y-12y[/tex]
∴ [tex]z=2x[/tex]
Thus, the third side is = [tex]2x[/tex]
Albert has a round box of crime filled chocolates the box has a diameter of 14 centimeters what is the box’s area
Answer:
Step-by-step explanation:
The formula for the area of a circle is pi*r^2, meaning pi times the radius squared. Since we know that the diameter is 14 centimeters, we know that the radius is half of that. The radius is 7. Now, we have to square 7. 7^2=49. So the answer is 49*pi, or approximately 153.93804
