Answer:

I think the answer is

$x = \frac{9}{7}$

Step-by-step explanation:

Reason :

$4x - 2 + 3x - 7 = 0 \\ collect \: like \: terms \\ 4x + 3x - 7 - 2 = 0 \\ 7x - 9 = 0 \\ 7x = 9 \\ x = \frac{9}{7}$

Therefore

$x = \frac{9}{7}$

Answer:

W = 8.2 cm

Step-by-step explanation:

The perimeter formula is P = 2W + 2L and here the perimeter is 65.6 cm.

Thus, 65.6 cm = 2W + 2L. Substituting 3W for L, we get

65.6 cm = 2W + 2(3W) = 8W.

Solving for W by dividing both sides by 8, we get W = 65.6 cm / 8, or

W = 8.2 cm

A metal bar weighs 7 Kg. 93% of the bar is Silver. How many Kgs of silver is there in the bar?

Sindrei [870]

<h3>Solution:</h3>

<u>From the given data</u>

<u>93% of the bar is silver :</u>

$\small\bold{ → 93\% \: \: of \: \: 7kg}$

$\small \bold{→\frac{93}{100} \times 7 }$

$\small \bold{→ \frac{651}{100} }$

$\small \bold{→ 6.51 \: kg }$

<u>Therefore, 6.51 Kg of Silver is there in the bar.</u>

The probability that a region prone to hurricanes will be hit by a hurricane in any single year is 0.1 and independent of other

ludmilkaskok [199]

Answer:

0.40951

Step-by-step explanation:

P(none in five years) = 1 - 0.1 = 0.9

P(at least one) = 1 - P(none in five years)

= 1 - $0.9^{5}$

= 1 - 0.59049

= 0.40951

So the probability of a hurricane hit at least once in the next 5 years is 0.40951
