Apples cost $0.75 per pound and bananas cost $1.05 per pound
LuckyWell [14K]

Answer:

<em>The baker bought 8 apples and 4 bananas</em>

Step-by-step explanation:

<u>System of Equations</u>

Let's call:

a = pounds of apples

b = pounds of bananas

The baker bought a total of 12 pounds of apples and bananas, thus:

a + b = 12      [1]

Apple cost $0.75 per pound and each pound of bananas cost $1.05 per pound. Thus the total cost is 0.75a + 1.05b. We know he spent a total of $10.20, thus

0.75a + 1.05b = 10.20     [2]

Solving [1] for a:

a = 12 - b       [3]

Substituting in [2]:

0.75(12 - b) + 1.05b = 10.20

Operating

9 - 0.75b + 1.05b = 10.20

Simplifying:

0.30b = 10.20 - 9 = 1.20

Dividing by 0.30:

b = 1.20/0.30

b = 4

From [3]:

a = 12 - 4 = 8

a = 8

Please help! I will give out brainlist.
Ainat [17]

Answer:

Step-by-step explanation:

This is a Pythagorean Theorem Question

c^2 = a^2 + b^2

c= sqrt(5)

a = x

b = x            This is an isosceles right triangle. The vertical side and the horizontal side are equal.

x^2 + x^2  =  sqrt(5)^2

2x^2 = 5                           Divide both sides by 2

x^2 = 5/2                          Take the sqrt of both sides.

√x^2 = √5 / √2                Multiply right side by √2 on both top and bottom

x = √5*√2 / √2*√2

x = √10 /2

Koalas absorb only 25% of the fiber they eat. A koala absorbed 10.5 ounces of fiber in one day. How many ounces of fiber did he
sweet [91]

\huge{\boxed{\text{42 ounces}}}

25% is equal to \frac{1}{4}, so multiplying it by 4 gets 100%.  This means we can multiply 10.5 by 4 to get 100% of the fiber the koala ate that day.

10.5*4=\boxed{42}
