4x plus 6 .. if i’m
wrong srryy
Answer:
√14 and √42. hope this helps.
Hello!
You can use the Pythagorean Theorem
c is the hypotenuse which is the side across the right angle
a and b are the other sides
Put in the values you know
Square the numbers
Subtract 25 from both sides
Take the square root of both sides
a = 10.9
The answer is D) 10.9 centimeters
Hope this helps!
Answer:
108
Step-by-step explanation:
All you need to do is take 3392 divided by 31.42 and you'll get 107.9567...
Since Lisa needs AT LEAST 3392 a month, she would have to work 108 hours in order to meet that requirement.
Answer:
0.1 or 1/10
Step-by-step explanation:
The digits 4, 5, 6, 7 and 8 are randomly arranged to form a three digit number, where the digits are not repeated.
This is question of permutation.
Imagine this sum as; there are 3 boxes(blank spaces for digits) and 5 different fruits(digits) are to be put in these boxes, where a box can hold a maximum of only 1 fruit. The number of such permutations are: ⁵P₃
By formula (a! is factorial a):
ᵃPₙ
⁵P₃
⁵P₃
⁵P₃
⁵P₃= 60
This is the total count of possible numbers that can be formed.
Now, for a number to be greater than 800 and even; first digit should necessarily be 8. Last digit can be 4 or 6. Using these conditions, there are 6 possibilities. 854, 864, 874, 846, 856, 876 are the numbers.
The probability that number is even and greater than 800 is:
