Answer:
She have $1133.33 in account which pays 5% annual interest and he have $1933.33 in account which pays 10% annual interest
Step-by-step explanation:
Let x be the amount she invested at 5% annual interest
She invested $800 more in 10%
So, she invested x+800 at 10% annual interest
Case 1:
Principal = x
Time = 1 year
Rate of interest = 5%
Case 2:
Principal = x+800
Time = 1 year
Rate of interest = 10%
Interest = Amount - principal = 880+1.1x-x=880+0.1x
Her total interest for a year is $250
So,
So the amount she invested at 5% annual interest is $1133.33
She invested at 10% annual interest=x+800=1133.33+800=1933.33
Hence she have $1133.33 in account which pays 5% annual interest and he have $1933.33 in account which pays 10% annual interest
Answer: Both are opposite. The opposite of both numbers are on the opposite ends of the number line.
You first have to add 2.7 inches and 2.1inches to get 4.8 inches from there you divide by 2 because you only added two number so your average rain fall is 2.4 inches
The 'similarity ratio' is their fancy name for the ratio of
corresponding sides of two drawings that are 'similar'.
In these similar pyramids . . .
-- the 9 of the small one corresponds to the 12 of the big one.
Their ratio is 9/12 = 3:4 .
-- the 18 of the small one corresponds to the 24 of the big one.
Their ratio is 18/24 = 3:4 .
Notice that they're the same ratio. If they WEREN't the same ratio,
then these two pyramids wouldn't be similar, even if somebody said
that they are.
The similarity ratio for these two figures is 3:4 .
Answer: 80
Step-by-step explanation:
Sin x = cos (90-x)
Like sin 30 = cos (90-30) =cos 60
So
90-x=90-80
Then
X=80
Verify your solution by finding the sum of the angles of sin and cos, it will be 90
