Answer:
Pythagoras theorem states that c²=a²+b²
14²=12²+x²
14²-12²=x²
196-144=x²
52=x²
√52=√x²
7.2111025509279785=x
rounded up to the nearest hundredth=7.21
Answer:
there isnt anything there but sure yes they are
Step-by-step explanation:
Answer:
((I do not have the answers for one, two, or four))
3.)
•What do you know?
-It’s about 425 miles from San Jose to Los Angeles and 320 miles from San Jose to Santa Barbara.
•What do you want to find out?
-How many miles it is from Santa Barbara to Los Angeles.
•What kind of answer do you expect?
-If using variable, I expect that I will get the number of miles from one city to the other.
5.)
425 = 320 + X
6.)
425 = 320 + X
Subtract 320 from both sides.
7.)
X = 105
From Santa Barbra to Los Angeles it is 105 miles.
8.)
320 + 105 = 425
Thx lolololoooopoooooooolol
Answer:the weight after 225 days is
22885 kilograms
Step-by-step explanation:
The initial weight of the blue whale calf at birth is 2725 kilograms. blue whale calf gains 90 kilograms of weight each day for the first 240 days after its birth. The weight increases in arithmetic progression. This means that the first term of the sequence, a is 2725, the common difference, d is 90.
The formula for the nth term of an arithmetic sequence is expressed as
Tn = a + (n - 1)d
Where
n is the number of terms of the sequence.
a is the first term
d is the common difference
We want to determine its weight, T225 after 225 days after it’s birth. It means that n = 225
Therefore
T225 = 2725 + (225 - 1)90
T225 = 2725 + 224×90 = 2725 + 20160
T225 = 22885
