Charlotte volunteered to deliver dinners for seniors. The supervisor told her to take half the meals to Oak Hill Senior Center,

Shalnov [3]

Answer:

Charlotte should take 5 meals to Glenview Apartment complex, 4 meals to North-side neighborhood center and 10 meals to Oak Hill Senior Center

Step-by-step explanation:

The given number of meals = 19 meals

The fraction of the meals to be taken to Oak Hill = (1/2)

The fraction of the meals to be taken to Glenview Apartment = (1/4)

The fraction of the meals to be taken to North-side neighborhood = (1/5)

Let <em>A</em> represent an even number of meals, we have;

The total meals she delivers = (1/2)·A + (1/4)·A + (1/5)·A = (19/20)·A

The remaining meals = A - (19/20)·A = (1/20)·A

Therefore, if the meals where 20, she would have an excess of 1 meal left

Therefore, the number of meals she can share using the given fractions = 19 meals

Therefore;

The number of whole meals she can take to Glenview = 20×(1/4) meals = 5 meals

The number of whole meals she can take to North-side neighborhood = 20 × (1/5) meals = 4 meals

Therefore, the number of meals she would take to Oak Hill Senior Center = (20 - 5 - 4) meals = 10 meals

A boat moves 15.0 km across a lake in 30.0 min. what was the average speed of the boat in kilometers per hours?

Katen [24]

To work out the average speed you would have to use the formula

AS = 15.0 ÷ 30.0 = 0.5 which is distance divided by time.

The you would do 0.5 x 60 = 30 (60 minutes = 1 hour)

So the average speed would be 30.0 km/h.

Lin has a scale model train. The model is created at a scale of 1 to 48. The height of the model train is 102 millimeters. What

mixas84 [53]

Answer:

4.896 meters

Step-by-step explanation:

"scale model" means that the original is shrunk or grown by some factor. So say we have a triangle with side lengths 5, 4 and 3. We could "scale" it by multiplying or dividing all three numbers by another number. So we could make it twice as big so the sides will be 10, 8 and 6 or cut it in half s the sides are 5/2, 2 and 3/2. We could also make it 48 times larger by multiplying everything by 48, so the sides would be 240, 192, 144.

That's what happened here. The original was shrunk by a scale factor of 48. or you could think of it as making the scale model grow by 48 times. So the height times 48 is the height of the real thing. You are also going to want to convert from millimeters to meters.

so 102*48= 4896 millimeters. Now we convert that into meters and we get 4.896 meters. let me know if you need any further explanation.

Find the values of s1 and r for a geometric sequence with s4 = 18 and s6= 8<br>

stiv31 [10]

Answer:

see below

Step-by-step explanation:

The ratio of terms that are two terms apart (s4 and s6) is the square of the common ratio:

s6/s4 = r^2

r = √(8/18)

r = 2/3 . . . . . matches choices A and C

Using the formula for the general term, we now know enough to find the first term:

sn = s1·r^(n-1)

s4 = s1·(2/3)^(4-1)

Using s4 = 18 and multiplying by (2/3)^-3, we get ...

18·(2/3)^-3 = s1 = 18·27/8

s1 = 243/4 . . . . . matches choice A
