Answer:

13 glue sticks cost $25.22

Step-by-step explanation:

We can use ratio's to solve this problem. We put price over number of sticks.

$7.76 x dollars

------------- = ---------------

4 sticks 13 sticks

Using cross products

7.76 * 13 = 4 * x

100.88 =4x

Divide each side by 4

100.88 /4 = 4x/4

$25.22 =x

There are blue, red and white counters in a bag in the ratio 16 3 2 There are 112 more blue counters than white counters. How ma

olga nikolaevna [1]

We will have 16 white counters in the bag.

Given that there are blue, red, and white counters in a bag in the ratio 16:3:2, the total number of balls will be:

Total = 16 + 3 + 2
Total = 21

If there are 112 more blue counters than white counters, then;

number of blues = number of white + 112

16x = 2x + 112

14x = 112

x = 8

Number of white counters = 2x = 2(8) = 16

Therefore we will have 16 white counters in the bag.

The midpoint of is point P at (−6,−2). If point E is at (2,−4), what are the coordinates of point F?

ipn [44]

Point F = (-2,-3); Apply the midpoint formula, (x1+x2/2),(y1+y2/2) = (x,y).

-6+2/2

-4/2

x=-2

-2+(-4)/2

-6/2

y=-3

(x,y)=(-2,-3)

Prove that {(tanθ+sinθ)^2-(tanθ-sinθ)^2}^2 =16(tanθ+sinθ)(tanθ-sinθ)

USPshnik [31]

First, expand the terms inside the bracket you will get

$(( \tan {}^{2} (x) + 2 \tan(x) \sin(x) + \sin {}^{2} (x) - ( \tan {}^{2} (x) - 2 \tan(x) + \sin {}^{2} (x) ) {}^{2} = 16( \tan(x) + \sin(x) )( \tan(x) - \sin(x) )$

$( 4 \tan(x) \sin(x) ) {}^{2} = 16( \tan(x) + \sin(x) )( \tan(x) - \sin(x) )$

$16 \tan {}^{2} (x) \sin {}^{2} (x) = 16( \tan(x) + \sin(x) )( \tan(x) - \sin(x) )$

$16 \tan {}^{2} (x) (1 - \cos {}^{2} (x) ) = 16 (\tan(x) + \sin(x) )( \tan(x) - \sin(x) )$

$16( \tan {}^{2} (x) - \frac{ \sin {}^{2} (x) \cos {}^{2} ( {x}^{} ) }{ \cos {}^{2} (x) }$

$16( \tan {}^{2} (x) - \sin {}^{2} (x) ) = 16( \tan(x) + \sin(x) )( \tan(x) - \sin(x) )$

$16( \tan(x) + \sin(x) )( \tan(x) - \sin(x) = 16( \tan(x) + \sin(x) )( \tan(x) - \sin(x) )$
