Fiona's Fashion Store is world renowned for its buttoned uniforms. A collection of 36 shirts and 42 jackets contains 842buttons.
Oduvanchick [21]
To solve the problem, what you must do is a system of two equations with two Ingonites that describe the problem.
 Let:
 x = number of shirt buttons.
 y = number of buttons on jackets.
 Writing the system:
 36x + 42y = 842
 6x + 7y = 137
 We observe that the system is linearly dependent, therefore, it can not be solved.
 However, the solution is to solve the system of two equations with two unknowns.
In order to solve it, the system must be linearly independent.

HOW DO I FIND THE PERIMETER OF A SEMICIRCLE WITH A RADIUS OF 9MM ?
dybincka [34]
Perimeter = 2 × π × r

Perimeter = 2 × 3.14 × 9

Perimeter = 56.52

Perimeter = 56.52 ÷ 2

Perimeter = 28.26

The perimeter of a semicircle with a radius of 9mm is 28.26

1.Use the simple interest formula to find the ending balance.
labwork [276]
General formula to be used: F=P(1+i)^n
F = future worth; P = present worth, i = annual interest, n = years

1.) F=5000(1+0.05)^{3.5}
    F = <span>$5931.06
</span>
2.) 3000+262.50=3000(1+i)^{3.5}
     i = 2.43%

3.) 1300+299=1300(1+0.0575)^{n}
     n = 3.7 = 4 years

4.) F=315(1+0.015)^{3}
     F = $329.39

5.) P+5=P(1+0.0125)^{1212}
     P = $1.45
     *I doubt the 1212 years. I think that is a typo error. Nevertheless, just           substitute the correct number of years to determine P :)

2. Vectors u and v are given by: u=5i-4j+ pk v=2i+tj-3k (a) Express p in terms of t when u and v are perpendicular. ​
Sindrei [870]

If u and v are perpendicular, then their dot product is zero:

\vec u \cdot \vec v = (5\,\vec\imath-4\,\vec\jmath+p\,\vec k) \cdot (2\,\vec\imath+t\,\vec\jmath - 3\,\vec k) = 10 - 4t - 3p = 0

Solve for p :

10 - 4t - 3p = 0

3p = 10 - 4t

\boxed{p = \dfrac{10-4t}3}
