Answer:

<u><em>14 pounds of strawberries and 42 pounds of peaches are sold</em></u>

Step-by-step explanation:

Suppose the pounds of strawberries sold are x and pounds of peaches sold are y. then

$182= x(1) + y(4)--------A

or 182= x(1) +3x(4)------- B

182=x+12x

182/13=x

x=14

Answer: the number of pounds of strawberries sold is 14 pounds and the number of pounds of peaches sold is 42 pounds

Step-by-step explanation:

Let x represent the number of pounds of strawberries sold.

Let y represent the number of pounds of peaches sold.

Amelia sold 3 times as many pounds of peaches as pounds of strawberries. This means that

y = 3x

Each pound of strawberries sells for $1 and each pound of peaches sells for $4. She made $182 altogether. This means that

x + 4y = 182 - - - - - - - - - - 1

Substituting y = 3x into equation 1, it becomes

x + 4×3x = 182

x + 12x = 182

13x = 182

x = 182/13 = 14

y = 3x = 3×14 = 42

The manager of a gas station has observed that the times required by drivers to fill their car's tank and pay are quite variable
maw [93]

Answer: 0.49

Step-by-step explanation:

The mean= E[x]=1/l= 7.5 min

l=1/7.5 =10/75=2/15

The exponential distribution's  probability density function is looking like that:

F(x)= l*e^(-l*x) = 2/15*e^(-2*x/15)

P(0<x<5)= e^(-0*2/15)- e^(-5*2/15)=1- e^(-2/3)= approx 0.49

F(x) = 4√(2x³-1)<br> F'(x) =.....?
goldfiish [28.3K]

Answer:

\large\boxed{f'(x)=\dfrac{12x^2}{\sqrt{2x^3-1}}}

Step-by-step explanation:

f(x)=4\sqrt{2x^3-1}=4\left(2x^3-1\right)^\frac{1}{2}\\\\f'(x)=4\cdot\dfrac{1}{2}(2x^3-1)^{-\frac{1}{2}}\cdot3\cdot2x^2=\dfrac{12x^2}{(2x^3-1)^\frac{1}{2}}=\dfrac{12x^2}{\sqrt{2x^3-1}}\\\\\text{used}\\\\\sqrt{a}=a^\frac{1}{2}\\\\\bigg[f\left(g(x)\right)\bigg]'=f'(g(x))\cdot g'(x)\\\\\bigg[nf(x)\bigg]'=nf'(x)\\\\(x^n)'=nx^{n-1}

Solve 6x+57=2x+315 . A. x=−911 B. x=911 C. x=119 D. x=−119
liubo4ka [24]

Explanation:

Remember: we have to isolate the variable x, so that means we have to get x by itself.

Step 1:

Let’s look at our equation:

6x+57=2x+315

Let’s subtract 2x from both sides of the equation, since our goal is to isolate the variable. You could also subtract 6x from both sides, but you would end up with a negative number, and I find it easier to deal with positive numbers.

6x(-2x)+57=2x(-2x)+315\\4x+57=315

Step 2:

Now, let’s subtract 57 from both sides of our equation.

4x+57(-57)=315(-57)\\4x=258

Step 3:

Since we have to isolate x, let’s divide both sides of the equation by 4.

4x/4=x\\258/4=64.5

Our final answer: x = 64.5

None of your options is the correct answer. Notify your teacher, tutor, etc. since there none of the options are correct.

One number is 6 more than another. the difference between their squares is 192. what is the numbers?
Masteriza [31]
Let the number be x.
then the number is (x + 6)
the difference between their squares is 192
(x + 6)² - x² = 192

expanding we get;

x² + 12x + 36 - x² = 192
12x + 36 = 192
12x = 192 - 36
12x = 156
x = 13

the numbers are 13 and 19.

hope this helps, God bless!
