In the morning, a farm worker packed 3 pints of strawberries every 7 minutes. In the afternoon, she packed 2 pints of strawberri
Doss [256]
Morning:
3 pints every 7 minute = 3/7 pints/minute = 0.429 pints/minute

Afternoon:
2 pints every 5 minutes = 2/5 pints/minute = 0.4 pints/minute

Difference:
3/7 - 2/5 = 15/35 - 14/35 = 1/35 pints/minute

0.429 - 0.4 = 0.029 pints/minute

Which expression is equivalent to (3m)(4m)2?
RoseWind [281]

Answer:

48m^3


Step-by-step explanation:

<em>We use the rule  (ab)^n=a^n*b^n  to first simplify this:</em>

(3m)(4m)^2\\=(3m)((4)^{2}*(m)^{2})\\=(3m)(16m^2)\\=(3*16)*(m)(m^2)


<em>Now we use the rule  a^x*a^y=a^{x+y} we simplify further and find the answer:</em>

(3*16)*(m)(m^2)\\=48m^{1+2}\\=48m^3

The third answer choice is right.

Food mix A contains 2​% ​fat, and food mix B contains 7​% fat. A 20​-kilogram diet mix of foods A and B is formed. If x kilogram
SashulF [63]

Answer:

The required expression is y = 1.4 - 0.05x

Step-by-step explanation:

Consider the provided information.

Food mix A contains 2% fat and food mix B contains 7​% fat.

Let x kilograms of food A are​ used, in a 20​-kilogram mixture.

Thus, 20 - x kilograms of food B are​ used, in a 20​-kilogram mixture.

Now It is given that A contains 2% fat and food mix B contains 7​% fat.

2% and 7% can be written as 0.02 and 0.07 respectively. Let represent the total fat with y.

Thus, the required expression is:

y = 2% (x) + 7% (20 - x)

y = 0.02 (x) + 0.07 (20 - x)

y = 0.02x + 1.4 - 0.07x

y = 1.4 - 0.05x

Hence, the required expression is y = 1.4 - 0.05x

15 Points - Please Help!
Ivan
<span>The first choice is correct.

Explanation<span>:

The formula for slope is m=(y</span></span>₂<span><span>-y</span></span>₁<span><span>)/(x</span></span>₂<span><span>-x</span></span>₁<span><span>). Once we find the slope using that formula, it goes in place of m in y=mx+b.

We do not yet have the y-intercept, but we can use one of the points to find it. We substitute the x-coordinate of one point in for x and the y-coordinate of the same point in for y; then we solve for b. This gives us the y-intercept.</span></span>
