Step-by-step explanation:

$2 \sqrt{7x} .3 \sqrt{14 {x}^{2} } \\ = 2 \times 3 \sqrt{7x \times 14 {x}^{2} } \\ = 6 \sqrt{7x \times 2 \times 7 {x}^{2} } \\ = 6 \sqrt{2 \times 7 \times 7 \times {x}^{2} \times x } \\ = 6 \times 7 \times x \sqrt{2 \times x} \\ = 42x \sqrt{2x}$

Umnica [9.8K]

Answer:

Julio debe $ 41225 al banco por concepto del préstamo para invertir en su casa.

Step-by-step explanation:

Dada la falta de información, asumimos que el préstamo fue realizado sin tasa de interés, de modo que la deuda solo sea el monto inicial menos las cuotas pagadas por quien recibe el préstamo, la cantidad de dinero que adeuda al banco es:

$x = \$\,100000 - \$\,32950 - \$\,25825$

$x = \$ \,41225$

Julio debe $ 41225 al banco por concepto del préstamo para invertir en su casa.

Put these over a common denominator 3/5 4/7?

Rama09 [41]

We can pick a common denominator by multiplying.

3*7/5*7= 21/35

4*5/7*5= 20/35

We have our common denom is 15.

Our fractions: 21/35 and 20/35

Simplify the expression

finlep [7]

Answer:

$\frac{2*x - 2}{2*x} - \frac{3*x + 2}{4*x} = \frac{x - 6}{4*x}$

Step-by-step explanation:

We have the expression:

$\frac{2*x - 2}{2*x} - \frac{3*x + 2}{4*x}$

The first thing we want to do, is to have the same denominator in both equations, then we need to multiply the first term by (2/2), so the denominator becomes 4*x

We will get:

$(\frac{2}{2} )\frac{2*x - 2}{2*x} - \frac{3*x + 2}{4*x} = \frac{4*x - 4}{4*x} - \frac{3*x + 2}{4*x}$

Now we can directly add the terms to get:

$\frac{4*x - 4}{4*x} - \frac{3*x + 2}{4*x} = \frac{4*x - 4 - 3*x - 2}{4*x} = \frac{x - 6}{4*x}$

Liz wants to estimate the percentage of people who rent their home. She surveys 320 individuals and finds that 176 rent their ho

SOVA2 [1]

Answer: 0.065

Step-by-step explanation:

Given : Sample size : n= 320

The sample proportion of people who rent their home : $p=\dfrac{176}{320}=0.55$

Significance level : $\alpha:1-0.98=0.02$

Then , Critical value : $z_{\alpha/2}=2.33$

The formula to find the margin of error : -

$E=z_{\alpha/2}\sqrt{\dfrac{p(1-p)}{n}}\\\\\Rightarrow\ E=(2.33)\sqrt{\dfrac{0.55(1-0.55)}{320}}\\\\\Rightarrow\ E=0.064799034281\approx0.065$

Hence, the margin of error for the confidence interval for the population proportion with a 98% confidence level =0.065

Kali is selling two different kinds of soup - tomato soup and clam chowder. She has a total of 80 bowls, so she can sell no more

algol13

You are looking for the shaded region that would be contained in both of the inequalities.

You have:
$x+y \leq 80$ $5x+10y\ \textgreater \ 500$

If you graph an shade the correct half-plane for those equations, you will see there is a triangular region on the left side of the first quadrant.
