. If x tan 45° sin 30° = cos 30° tan 30°, then x is equal

Answer:

x = $\frac{\sqrt{3} }{3}$

Step-by-step explanation:

You can either use the unit circle to find your values and then solve for x or plug it into the calc directly to find your answer (don't forget to put your mode on deg!). It is much faster to plug it into your calc. Simply just divide both sides by tan45°cos30° and you should isolate x and find your answer.

Massimo ate 24 hotdogs in a hotdog eating contest, which was about 125% of the number of hotdogs eaten by his twin Tao. Approxim

lakkis [162]

Tao ate 19 hotdogs approximately.

Step-by-step explanation:

Given,

Number of hotdogs eaten by Massimo = 24

This represents 125% of the hotdogs eaten by his twin Tao.

Let,

x be the number of hotdogs eaten by Tao.

125% of x = 24

$\frac{125}{100}x=24\\1.25x=24$

Dividing both sides by 1.25

$\frac{1.25x}{1.25}=\frac{24}{1.25}\\x=19.2$

Rounding off to nearest whole number

x=19

Tao ate 19 hotdogs approximately.

Kim purchased white vases, red vases, and flowers to create centerpieces for an event. The flowers cost a total of $336 and each

laiz [17]

Option A:

I and III only the answers.

Solution:

Let white vases be "w" and red vases be "r".

Cost of total flower = $336

Cost of each vase = $11

Total cost of the centerpieces

= Cost of (white vases + red vases) + Cost of flowers

= 11(w + r) + 336

= 11w + 11r + 336

Total cost of the centerpieces = 11w + 11r + 336 = 11(w + r) + 336

Therefore I and III only the answers.

Option A is the correct answer.

Consider the following IP problem:

Liono4ka [1.6K]

Answer:

$(3,0)$

Step-by-step explanation:

The integer points which fall in the common region bounded by the lines are

$(0,2),(2,3),(3,0)$

Since, one of the points is $(2.22...,3.11....)$ we round it to $(2,3)$

If we round up then the point will be $(3,4)$ which does not fall in the bounded region.

Also $x_1\geq 0$ and $x_2\geq 0$ no negative values are considered.

Applying in the values in the LP problem $Z=5x_1+x_2$

$Z=5\times 0+2\\\Rightarrow Z=2$

$Z=5\times 2+3\\\Rightarrow Z=13$

$Z=5\times 3+0\\\Rightarrow Z=15$

So, the LP problem is maximum at point $(3,0)$ .
