Answer:

120 m

Step-by-step explanation:

LCM of 1.6 and 15 will give us the distance

Put 1,6 and 15 in same format:

16/10= 2*2*2*2/10
150/10= 2*3*5*5/10

LCM= 2*2*2*2*3*5*5/10= 120 m

So the next point is 120 m apart

What is the value of B??

Maurinko [17]

The answer is 3.75.

Since the length of 'b' is one-half that of 7.5 based on the diagram (we know this because the partial radii connecting the two lines, or chords, are the same length, meaning the two chords are equal);

7.5 ⇒ 3.75

Alex went to the grocery store and bought 5 avocados. He paid $10 and received $4.50 in change. How much did each avocado cost i

Delvig [45]

Answer:

$1.10

Step-by-step explanation:

We have been that Alex went to the grocery store and bought 5 avocados. He paid $10 and received $4.50 in change.

First of all, we will find amount paid for 5 avocados by subtracting $4.50 from $10.

$\text{Amount paid for 5 avocados}=\$10-\$4.50$

$\text{Amount paid for 5 avocados}=\$5.50$

Now, we will divide $5.50 by 5 to find cost of each avocado.

$\text{Cost of each avocado}=\frac{\$5.50}{5}$

$\text{Cost of each avocado}=\$1.10$

Therefore, the cost of each avocado is $1.10.

Last year, sales at Company X were 10% greater in February than in January, 15% less in March than in Feb, 20% greater in April

Svetlanka [38]

Answer:

d. May

Step-by-step explanation:

Working through the chain, we have ...

Feb = 1.10×Jan

Mar = 0.85×Feb = 0.935×Jan

Apr = 1.20×Mar = 1.122×Jan

May = 0.90×Apr = 1.0098×Jan

Jun = 1.05×May = 1.06029×Jan

The multiplier that is closest to 1 is 1.0098, so May has sales closest to January.

_____

The percentage increase or decrease can be converted to a multiplier by adding it to 1. If p% is the percentage change, then adding it to an original value looks like ...

original + p% × original = original × (1 +p%) . . . . . . . distributive property

And p% translates to a decimal number by replacing % with /100 or ×0.01.

10% increase: original × (1 + 10/100) = original × 1.10

15% decrease: original × (1 - 15/100) = original × 0.85
