Answer:
Is there supposed to be a picture?
Step-by-step explanation:
1. You convert the fractions so that they will have the same denominator because you can't multiply if the denominators aren't the same.
- 2/3 times 5/5 which equals 10/15
- 1/5 times 3/3 which equals 3/15
2. Now that the denominators are the same we can multiply the fractions.
- 10/15 times 3/15 equals 30/15
3. Since we have the answer we need to simplify and 30/15 simplified is 2.
So the answer is 2 or 30/15
Cubic functions usually look like an S
Answer:
$830
Step-by-step explanation:
Samer's salary each month is $3,650. He spends $1,160 on rent. He breaks the rest of his earnings into 3 other monthly expenses. How much money was in each part?
Step 1
$3,650 - $1,160
= $2490
Step 2
He breaks the rest of his earnings into 3 other monthly expenses. How much money was in each part?
Hence,
$2490/3
= $830
The amount of money in each part = $830
The distance between point on the ground from the top of the building is 396 meter, if the building is 280 m high and The angle of depression from the top of a building to a point on the ground is 45 degrees.
Step-by-step explanation:
The given is,
The angle of depression from the top of a building to a point on the ground is 45 degrees.
Height of the building is 280 meter.
Step: 1
Given diagram is a right angled diagram,
For right angle triangle,
90° = 45° + 45°
= 90°
Trignometric ratio,
sin ∅ = ....................(1)
For the above ratio take the bottom angle, that is angle of depression from the top of a building to a point on the ground is 45 degrees.
Where, Opp side = 280 meters
Hyp side = x
∅ = 45°
Equation (1) becomes,
sin 45° =
0.70710678 =
x =
x = 395.979
Distance between point on the ground from the top of the building, x ≅ 396 meter
Trignometric ratio,
cos ∅ =
Cos 45 =
Adj = (0.70710678)(396)
Bottom length, Adj = 280 meter
Result:
The distance between point on the ground from the top of the building is 396 meter.
