Answer:

5 i hope this helps :)

Step-by-step explanation:

a = √c2 - b2

= √132 - 122

= √25

= 5

∠α = arcsin (a/c)

= arcsin (5/13)

= arcsin (0.38461538461538)

= 0.39479 rad = 22.62° = 22°37'12"

∠β = arcsin (b/c)

= arcsin (12/13)

= arcsin (0.92307692307692)

= 1.17601 rad = 67.38° = 67°22'48"

h = a × b over c

= 5 × 12 over 13

= 4.61538

A company will need 25,000 in 7 years for a new additon. To meet this goal, the company deposits money into an account today tha

Mrac [35]

You can use the simple interest formula
$P = irt$

We need P, which is the primary (or principal) investment, and we know that:

rate = 3% (0.03)
time = 7
i = $25000

So, just plug in and solve:
$I = 25000(0.03)(7)$
$I = 5250$

The company needs to invest $5250 today, to make $25000 in 7 years.

Adrianne is planning to bake some chocolate, strawberry, and raisin muffins for a party. She was asked to bake half as many choc

Genrish500 [490]

Answer: She can bake 160 raisin muffins.

Step-by-step explanation:

Let the number of raisin muffins be 'x', then

The number of chocolate muffins = $\frac{1}{2}x$

The number of strawberry muffins= $3\times(\frac{x}{2})=\frac{3x}{2}$

Since, the total muffins she can bake 480.

Therefore,

$x+\frac{x}{2}+\frac{3x}{2}=480\\\Rightarrow\frac{2x+x+3x}{2}=480\\\Rightarrow\frac{6x}{2}=480\\\Rightarrow\ x=\frac{480\times2}{6}\\\Rightarrow\ x=160$
