Answer:
Ruth receives £150
Step-by-step explanation:
sum the parts of the ratio, 3 + 5 + 7 = 15 parts
divide the total £750 by 15 to find the value of one part of the ratio
£750 ÷ 15 = £50 ← value of 1 part of the ratio
Then
3 parts = 3 × £50 = £150 ← amount Ruth receives
rotates, the ray at an angle 8 makes a spot of light
that moves along the shore. The lighthouse is
located 500 m from the shoreline and makes
one complete rotation every 2 min.
Determine the equation that expresses the
distance, d, in metres, as a function
of time, t, in minutes.
Answer:
Step-by-step explanation:
The equation can be derived using the following trigonometric identity:
That is:
In this case, the opposite side is the distance from the lighthouse to the shoreline and the adjacent side is the distance from the lighthouse to the spot of light on the shoreline (500m)
The angle is equal to the angle of the light beam.
It is changeable according to the time. so,
Substituting these values into the trigonometric identity gives us the following equation:
Solving for d gives us the following equation:
Therefore, the equation to express the distance, d, in metres, as a function of time, t, in minutes is:

Answer:
6:9:15
Step-by-step explanation:
multiply each number in the first ratio by three. They multiplied 3 times three to get 9, so you have to do that to each number to make it a ratio.
A ratio is like an equivalent fraction. It all has to be proportionate to the other fraction.
Examples:
4:3 is equal to 8:6
16:6 is equal to 32:12
Answer: 6 :9:15
Step-by-step explanation:
3x3=9
2x4=6
5x3=15
