What is the surface area of a rectangular prism that has a length of 18 inches, a width of 1 foot, and a height of 14 inches?
252 in. 2
3,024 in. 2
1,272 in. 2
568 in. 2
Answer:
C
Step-by-step explanation:
Givens
L = 18 inches
W = 1 foot = 12 inches
H = 14 inches
Surface Area = 2 * L*w + 2*L * h + 2*w*h
Surface Area = 2 * 18*12 +2*18*14 + 2*12*14 all in linear inches
Surface Area = 432 + 504 + 336 all in square inches
Surface Area = 1272 in^2

Answer:
361
Step-by-step explanation:
20^2 =400
19^2 = 361
answer is 19
The square of 19 is 361 which lies between the numbers 350 and 390.
What is Algebra?The analysis of mathematical representations is algebra, and the handling of those symbols is logic.
The square of a number is the multiplication of that number with itself.
The square number between 350 and 390 will be given as,
We know that the square of 18 is 324 and the square of 20 is 400.
The square of 19 is given as,
19 × 19 = 361
Then the square of the 19 will be 361.
Then the square of 19 is 361 which lies between the numbers 350 and 390.

Answer:
55 - 56i² + 94i
Step-by-step explanation:
11(5 + 6i) - 7i(8i - 4)
=> 55 + 66i - 56i² + 28i

what is the volume for 7 1/2 cm by 12 cm by 15 1/2?
Answer:
1/(1/8)= 8 cubes
Step-by-step explanation:
Volume of a rectangular prism is length × height × width
Length=7 1/2
Width= 15 1/2
Height=12
Volume of the prism is therefore:
7 1/2×12×15 1/2= 1395cm3
No of cubes with edge length 1/2 to fit into the prism will be:
Volume of cube is L*W*H
1/2*1/2*1/2= 1/8cm3
Therefore the no of cubes to fit into the Prism will be:
1395/(1/8)= 11160 cubes.
If one was stuck,the number of 1/2 edge length cube to fit into 1cm will be:

How much of a radioactive kind of ruthenium will be left after 8 hours if you start with 3,888
grams and the half-life is 4 hours?
grams
Submit
Answer:
Step-by-step explanation:
As an example, iodine-131 is a radioisotope with a half-life of 8 days. It decays by beta particle emission into xenon-131. After eight days have passed, half of the atoms of any sample of iodine-131 will have decayed, and the sample will now be 50% iodine-131 and 50% xenon-131.
50 grams to 25 grams is one half-life. 25 grams to 12.5 grams is another half-life. So, for 50 grams to decay to 12.5 grams, two half-lives, which would take 36 days total, would need to pass. This means each half-life for element X is 18 days.
Answer:
After 8 hours or 2 half-lives, you will have 972 grams of ruthenium left.

Which equation describes the line above?
A. y= -4x-5
B. y= -1/5x-4
C. y= -5x-4
D. y= -4x-1/5
Answer:
y = -1/5x -4
Step-by-step explanation:
We know the y intercept is -4 since it crosses the y axis at -4
The slope is negative since it goes down from left to right
Take two points on the line
(0,-4) and (5,-5)
We can find the slope using the slope formula
m = ( y2-y1)/(x2-x1)
= ( -5- -4)/( 5 -0)
= (-5+4)/ ( 5-0)
= -1/5
The equation for the line in slope intercept form is y = mx+b where m is the slope and b is the y intercept
y = -1/5x -4
