Sin74 = Cos16
cause 16 + 74 = 90
Whenever the sum of two angles is equal with 90, the Sin of one is equal with the Cos of the other like :
Sin(30) = Cos(60)
and also
Tan(30) = Cot(60)
Answer:
Brother is 70.5 and sister is 64.5
Step-by-step explanation:
you will need to set up a simple equation and give out variables.
Girls age = 6-x
Brother's age= x
the you will take those 2 and add them and place them equal to 135:
6-x+x=135
6-2x+6=135+6
The 6 cancels out
2x=141
2x/2=141/2
x=70.5
The brother's age would be 70.5 then and the girl's would be 64.5
Answer:
The 3 feet fabric will cost $ 1.09728 almost $ 1.10
Step-by-step explanation:
First we will find out how many meters 3 feet will be.
1 feet = 0.3048 meters
She needs 3 feet of fabric
3 *1 feet = 3* 0.3048 ( multiplying both sides by 3)
3 feet = 0.9144 meters
Using the unitary method we will find the cost of 3 feet of fabric
1 meter costs $ 1.20
0.9144 *1 meter costs $ 1.20 * 0.9144 ( multiplying both sides by 0.9144)
0.9144 meter = $ 1.09728
The 3 feet fabric will cost $ 1.09728 almost $ 1.10
Answer:
H. $360.71
Step-by-step explanation:
The 1 in $435.15 is in the tenths place. It has a value of 1/10. One tenth that value is 1/100. To have that value, a 1 would need to be in the hundredths place: 0.01.
Of the offered choices, the only one with a 1 in the hundredths place is ...
H. $360.71
