Answer 1

Answer:

Answer:

see explanation

Step-by-step explanation:

The volume (V) of a rectangular prism is calculated as

V = lbh ( l is length, b is breadth and h the height ), thus

V = 6 × 1 $(1)/(5)$ × 4 $(1)/(2)$ → C

To evaluate the volume change the mixed numbers to improper fractions

V = 6 × $(6)/(5)$ × $(9)/(2)$

= $(6(6)(9))/(5(2))$

= $(324)/(10)$ = $(162)/(5)$ = 32 $(2)/(5)$ yd³ ( = 32.4 yd³← in decimal form )

What is the slope of the line that passes through the pair of points (-10,14) and (-6,12).

Answers

Answer:

Step-by-step explanation:

(-10,14) and (-6,12)

y2 = 12, y1 = 14, x2 = -6, x1 = -10

Slope m = (y2 - y1)/(x2 - x1)

m = (12 - 14)/(-6 + 10)

m = -2/4

m = -1/2

The equation of line

y - y1 = m(x - x1)

y - 14 = -1/2(x + 10)

y - 14 = -x/2 - 5

y = -x/2 - 5 + 14

y = -x/2 + 9

X and Y are continuous values, both measured to 2 significant figures. X=230 and Y=400. work out the greatest possible value of X/Y^2.(this is on an upper and lower bounds sheet)

Answers

"Two significant figures" means that a digit after the second one could actually be anything ... it wasn't measured. 'X' could be anything from 230 to 239. 'Y' could be anything from 400 to 409.The greatest possible value of that fraction is. (239)/(409 squared) .

47 minus 3 times the difference of 15 and 2

Answers

Lets change those words to numbers
47 minus 3 times the difference of 15 and 2
47-3(15-2)
Now we have to take the order of operations into consideration.
Parenthesis
Exponents
Multiplication/Division
Addition/Subtraction
Lets clear out the parenthesis.
47-3(15-2)
47-3(13)=47-39=8
Therefore, the final answer is 8

Answer:

Step-by-step explanation:

47 minus 3 times the difference of 15 and 2:

47 - 3(15-2) = 47 - 3(13) =47 - 39 = 8

47 minus 3, times the difference of 15 and 2:

(47-3) (15-2) = (44)(13) = 572

What is the probability of selecting a red card from a standard deck of 52 playing cardships that does not contain a joker?

Answers

We know that the deck of cards contain half red and half black cards or you can say we have 26 red cards and 26 black cards.
we have to find probability of red cards from a deck of cards
so,
probability (selecting red card) = $(26)/(52)$
= $(1)/(2)$

Probability ( selecting red card ) = $(1)/(2)$ Answer

1/2. half of the cards(26 out of 52) are red. you can reduce 26/52 to 1/2.
