: 4.1B; 4.10B)
Paha777 [63]

Answer:

C. $16.00

Step-by-step explanation:

First, let's find how much they profit from one loaf

The profit is the difference between how much they sell it for and what they buy it for.

So, we can subtract what they buy the bread for from how much the sell it for

selling price-buying price

2.40-0.80=1.6

So, they profit $1.60 per loaf

To find how much they profit for 10 loaves, multiply their profit from one loaf by 10

profit*10

1.60*10=16

The profit for 10 loaves is $16, or choice C

Right triangle XYZ is shown. Y (2,6) (1, 2) 6 х 7 Z Rounded to the nearest hundredth of a unit, what is the length of the hypote
Dmitriy789 [7]

Answer:

8.12

Step-by-step explanation:

We obtain the distance between x and y

d = sqrt[(x2 - x1)² + (y2 - y1)²]

d = sqrt[(1 - 2)² + (2 - 6)²]

d = sqrt[1 + 16)

d = sqrt(17)

d² = 17

From Pythagoras rule;

Hypotenus = sqrt(Adjacent² + opposite²)

Hence,

Hypotenus = sqrt(17 + 7²)

Hypotenus = sqrt(17+ 49)

Hypotenus = sqrt(66)

Hypotenus = 8.124

Hypotenus = 8.12
