In the way you asked the question, the answer is already there but I am going to assume u are asking how many bracelets you can make which would then put the answer at almost 9 bracelets.

Answer:

$15\ units$

Step-by-step explanation:

we know that

If two figures are similar, then the ratio of its corresponding sides is equal and the corresponding angles are congruent

In this problem Triangles PQT and RQS are similar by AA Similarity Theorem (The three angles are congruent)

therefore

$\frac{12}{16}=\frac{x}{20}\\ \\x=12*20/16\\ \\x=15\ units$

Find the compound interest and final amount $950 for 2 years at 7½ per annum

wlad13 [49]

Answer:

1092.50 account value

142.50 interest

Step-by-step explanation:

to solve compound interest questions we use the formula A=P(1+rt) where P is the principal (initial investment) r is the rate or the return (7.5%) and t is the interval or time so 2 years

now putting it together we get A=950(1+ (7.5x2)) = 1092.50 $

the interest is this value A minus the initial investmetn so 1092.50 - 950 = 142.50$

What is the maximum height of the basketball when the player passes the ball to someone? Initially, the ball moves at a speed of

ZanzabumX [31]

Answer with explanation:

Since the motion of the ball is projectile motion we shall use the equations for projectile motion.

The maximum height achieved by the projectile is given by

$h_{max}=\frac{v_{o}^{2}sin^{2}(\theta )}{2g}$

Applying the values we get

$h_{max}=\frac{12^{2}\times sin^{2}(45)}{2\times 9.81}\\\\h_{max}=3.669m$

The range of the projectile is given by

$R=\frac{v_{o}^{2}sin(2\theta )}{2g}$

Applying values we get

$R=\frac{12^{2}\times sin(2\times 45 )}{2\times 9.81}\\\\R=7.339m$

thus the maximum horizontal distance reached by the ball equals 7.339 meters after which it bounces thus a person standing 8 meters away will not be able to catch it.

(The height of the players is not taken into account since no info is given about their height.)

What is the solution to the system of equation 2y - x = 8, and y - 2x = -5

gladu [14]

Answer:

Step-by-step explanation:

-x + 2y = 8

-2x + y = -5

2x - 4y = -16

-2x + y = -5

-3y = -21

y = 7

-x + 14 = 8

-x = -6

x = 6
