Answer: 16 and one third lbs

7/3 is the amount of flour needed for one loaf, so you multiply that by 7

The answer is 49/3, or 16 and one third

Answer:

16 1/3 lbs

Step-by-step explanation:

We can write a ratio to solve

7 lbs x lbs

-------------- = -------------

3 loaves 7 loaves

Using cross products

7 * 7 = 3x

49 = 3x

Divide each side by 3

49/3 = 3x/3

16 1/3 lbs

Ok....
Simplified would be 12.40
Squared would be 153.99 or fraction form would be 83 + 12 $\sqrt{35}$

A chemist is conducting an experiment which involves a certain chemical reaction. He begins the experiment with 666 milliliters

Ket [755]

Answer:

8 Minutes

Step-by-step explanation:

since we are trying to find how many minutes have passed we first need to find how much substance was used during the time. we can do that by subtracting the leftover substance from the amount we started with.

666-562 = 104

Now that we know how much substance was used we can then use our conversion rate (13 per minute) and find how many minutes have passed by dividing.

104 / 13 = 8

An exponential function is expressed in the form y=axb^x. The relation represents a growth when _______ and a decay when ______.

seropon [69]

Answer:

Growth when: b>1.

Decay when: 0<b<1.

Step-by-step explanation:

Any function in the form $f(x)=a{\times}b^x$ , where a > 0, b > 0 and b not equal to $1$ is called an exponential function with base b.

If 0 < b < 1 this is an example of an exponential decay.

The general shape of an exponential with b > 1 is an example of exponential growth.

Hence,

An exponential function is expressed in the form $f(x)=a{\times}b^x$ , The relation represents a growth when b >1 and a decay when 0<b<1.

On a coordinate plane, a solid straight line has a positive slope and goes through (0, negative 1.3) and (3, negative 0.3). Ever

blsea [12.9K]

Answer:

Step-by-step explanation:

$slope=\frac{-0.3-(-1.3)}{3-0}=\frac{1}{3}\\eq.~of~line~is y-(-1.3)=\frac{1}{3}(x-0)\\y=\frac{1}{3}x-1.3\\as~it~is~shaded~to~the~right~so~y\leq \frac{1}{3}x-1.3~satisfies ~it.$
