Answer:

x = 3

Step-by-step explanation:

The smaller triangle and larger one are similar, so corresponding sides are proportional.

8/4 = (8 +(x -1))/5

10 = x +7 . . . . . . . . . multiply by 5 and simplify

3 = x . . . . . . . . . subtract 7

Alternate solution

The short segments are also proportional:

(x -1)/(5 -4) = 8/4

x -1 = 2 . . . . simplify

x = 3 . . . . . . add 1

What is the dollar amount of the Gentry's annual food and housing budgets combined?

Pavlova-9 [17]

Answer:

The combined amount is $14871.21.

Step-by-step explanation:

It is given that, the total yearly income of gentry family is $29742.42

The % charge on income for food is 20%.

The % charge on income for housing is 30%.

The amount in dollar from % form is given by,

= $(\frac{percent form}{100})(annual income)$

For annual food,

= $(\frac{20}{100})(29742.42)$

= $5948.484

For housing budgets,

= $(\frac{30}{100})(29742.42)$

= $8922.726

Thus the combined amount is,

= $8922.726 + 5948.484 = 14871.21$

= $14871.21

Solve for x in the given interval. sec x= -2√3/3, for π/2 ≤x≤π

drek231 [11]

Answer:

b. $x=\frac{5\pi}{6}$

Step-by-step explanation:

The given function is

$\sec x=-\frac{2\sqrt{3} }{3},\:\:for\:\:\frac{\pi}{2}\le x \le \pi$

Recall that the reciprocal of the cosine ratio is the secant ratio.

This implies that;

$\frac{1}{\cos x}=-\frac{2\sqrt{3} }{3}$

$\Rightarrow \cos x=-\frac{3}{2\sqrt{3} }$

$\Rightarrow \cos x=-\frac{\sqrt{3}}{2}$

We take the inverse cosine of both sides to obtain;

$x=\cos^{-1}(-\frac{\sqrt{3}}{2})$

$x=\frac{5\pi}{6}$

10. A toy store received a shipment of 17 cases of

ozzi

There are 204 teddy bears in the shipment.

Step-by-step explanation:

Total number of cases received = 17 cases

Total number of bears in the shipment = Cases received * Bears per case

Total number of bears = $17*12$

Total number of bears = 204

There are 204 teddy bears in the shipment.
