Answer:

a) 23%

Step-by-step explanation:

To find the price change as percentage :

Multiply 100 by 160 then divide it by 130

100 × 160 ÷ 130 = 123 approximately which means there's an additional 23% to the 100% price

Now, use your research to decide which business is the best choice for this community.
larisa86 [58]

Answer:


Step-by-step explanation:

the best business for this area is The Shoe Hut. This is the case for several reasons. First, there is less competition for custom sporting goods, as the supply in the area is lower. Survey data shows that there are more individuals who desire custom outdoor sporting goods than there are people who desire more coffee shops. Finally, the overall capital required to start and maintain The Shoe Hut is lower. Less equipment is needed, any building can be rented, and if an employee cannot be hired immediately, I can run the store on my own.

Carl has new bottle of laundry detergent he uses 0.4 cups of laundry detergent while washing one load of laundry and 0.7 coupon
oee [108]

Answer:

-1.1 cups

Step-by-step explanation:

To find out how much was spent on the main bottle of detergent, we must add the expenses that were incurred in the wash.

The statement tells us that first there is an expense of 0.4 cups of laundry detergent while washing one load of laundry and 0.7 coupon another load, therefore this means that the change in the bottle would be:

(-0.4) + (-0.7) = -0.4 - 0.7 = -1.1 cups.

In other words, the main bottle would have 1.1 cups less, that is, -1.1 cups.

I think the best option here is B. <span>period 2pi/3 and asymptote at x=0
</span>because period of tanx is pi so period of tan(3/2x) is pi/(3/2) = 2pi/3. I hope this can work good for you.

If the sin 90º = 1, then which statement is true?
Natali [406]

in a right-triangle, like in the 1st Quadrant, cosine and sine are complements, so then

sin(x) = cos(90° - x)

cos(x) = sin(90° - x)

for this case, sin(<u>90°</u>)  = cos(90° - <u>90°</u>), or just cos(0°) = 1.
