Answer:
B
Step-by-step explanation:
ac =5x
cb=7x
(5x×5x)+ (5 +7)^2 = 7x^2
25x^2+144=49x^2
x=kök 6
ac =5kok 6
(5kok6)×12÷2= 30 kök 6
We randomly select one card from 52, so there are 52 outcomes and:
We also know, that there are
face cards in a standard deck (
) and only three of them are diamonds, so
With this informations, we can calculate our probability:
first use the formula it is 1/3 × base area × height =volume of pyramid
so we just need to replace some of the information given in the statement to our formula
so it's going to be,i'll let the height as unknown X
128=1/3 × (8 × 8) × X
so it's going to be
128=64/3X
so X is 128 ÷ 64/3=6cm
Answer:
-28/3
Step-by-step explanation:
The formula for slope is [ y2-y1/x2-x1 ].
15-(-13)/-12-(-9)
28/-3 or -9 1/3
Best of Luck!
