Answer:
40
Step-by-step explanation:
one cubic cm would be 2x2x2=8 half cm³
you have 1x2x2.5 cm cube = 5 cm³
5 x 8 = 40
another way to look at it:
2 1/2 = 5 half-cubes long
2 = 4 half cubes wide
1 = 2 half cubes tall
5 x 4 x 2 = 40

Answer:
Chad is incorrect
Step-by-step explanation:
Since A is in quadrant 2, we know the x must be negative and y is positive. Therefore, if we add a negative sign in front of both x and y, x will become positive, and y will become negative. However, in the 3rd quadrant, both x and y must be negative, which is not the case here. Hence, Chad is wrong.

Step-by-step explanation:
To isolate the variable of x, simply add 16 to 11 which is 27 and now it is set up as 4.5x=27 and 27/4.5, it = 6
Answer:
Gray and all are right.
Step-by-step explanation:
4.5x + 16 = 11.5
4.5x = 11.5 - 16
4.5x = -4,5
x = -4.5/4.5
x = -1
4.5x + 27 = -9
4.5x = -9 - 27
4.5x = -36
x = -36/4.5
x = -8
4.5x - 16 = 11
4.5x = 11 + 16
4.5x = 27
x = 27/4.5
x = 6
-4.5x + 27 = 45
-4.5x = 45 - 27
-4.5x = 18
x = 18/-4.5
x = -4

Dracula's bill at the restaurant was $54.83. He left a tip of 15%.
What was the tip amount (nearest hundredth)?
PLEASE ANSWER QUICK :,(
15% as a decimal is 0.15
Multiply the amount of the bill by the percentage:
54.83 x 0.15 = 8.22
The tip was $8.22
Answer:
[tex]\huge\boxed{ \$ \ 8.22}[/tex]
Step-by-step explanation:
Bill = $54.83
Tip = 15 % of 54.83
[% means out of 100, "of" means to "multiply"]
Tip:
= 15% of 54.83
= 15 / 100 * 54.83
= 0.15 * 54.83
= $ 8.22

A shop has a slae that offers 20% off all prices On the final day they reduce all the sale prices by 25% Linz buys a radio on the final day Work out the overall percentage reduction on the price of the radio
Answer:
40%
Step-by-step explanation:
We would use an example
assume the price of the radio is 100
After the initial price reduction, it would be worth (100 - 20%) 80% of the price
0.8 x 100 = 80
After second price reduction it would be worth (100 - 25% ) 75% of the price
0.75 x 80 = 60
Price change = (new price after all the discounts / original price) - 1
(60/100) - 1 = -0.4
line y=3x-1 is transformed by a dilation with a scale factor of 2 and centered at (3,8) what is the lines image in an equation form
Answer: 4)y=3x-1
Step-by-step explanation:
The y value relates to the dilatation center, which the line image's equation will be [tex]y = 3x - 1[/tex]. In standard form, [tex]y = mx + b[/tex] y-intercept is represented by the letter b.
Center of dilatation calculation:[tex]y = 3x - 1[/tex] is the equation of a line.
If somehow the line is dilatable by a factor of 2 and centered at [tex](3, 8)[/tex]. To begin with, we must determine the y-value for which [tex]x = 3[/tex].
[tex]y = 3(3) - 1\\\\y = 9 - 1\\\\y = 8[/tex]
This equation of the line image will be [tex]y = 3x - 1[/tex], because the y value is comparable to the center of dilatation.

Answer this using a graphing method!
Step-by-step explanation:
5x-2y=10
x-y=-1
Addition method
multiply the second equation by -2 and add it to the first one
5x-2y=10
-2x+2y=2
Total 3x=12
Divide by sides by 3
x=4
Now multiply the second equation by -5 and add it to the first one
5x-2y=10
-5x+5y=5
3y=15
Divide both sides by 3
y=5
Solutions are x=4 and y=5
2nd method
if x-y=-1, so x=y-1
bring the value of x in the first equation
5(y-1)-2y=10
5y-5-2y=10
put the similar term together
3y=15
Divide both sides by 3
y=5
now bring the value of y in one of the equation
x-y=-1
so x-(5)=-1
x=-1+5
x=4
Solutions are x=4; y=5

a. Find the probability that a randomly chosen 5th grader will take more than 2.5 minutes to complete the problem.
Answer
0.266
Step-by-step explanation:
x ~ N(2,0.[tex]8^{2}[/tex])
P(x>2.5)
=P(Z>[tex]\frac{2.5-2}{0.8}[/tex])
=p(z >0.625)
=1- Φ(0.625)
= 1 - 0.734
=0.266
