Answer:
x= 11.25
Step-by-step explanation:
cross multiply 9 by 5 divided by 4 and that would give you x
Answer:
B
Step-by-step explanation:
- 3/2 is - 1.5 , and B is - 1.5
Answer:
B. 0.12
Step-by-step explanation:
To obtain this probability, you need to multiply the two probabilities.. since it's comprised of two events: one that he's in the brass section, one that he plays trombone. The probably of him playing trombone only happens if he's in the brass section.
So, you have the possibility he's in the brass section: 0.50
The possibility he's playing trombone, if he's in the brass section: 0.24
P = 0.5 * 0.24 = 0.12
Honestly just use a calculator
Answer:
Step-by-step explanation:
a) Set up the variables:
Let <u>x</u> represent the width; Then <u>2x</u> will represent the length.
b) What is the equation that represents the above situation?
<u>Use perimeter formula:</u>
As we set up w = x and l = 2x, and we know that the perimeter is 30 cm, we can build an equation by substituting the values we know or set up:
c) solve the equation
- 30 = 2( 2x + x)
- 30 = 2(3x)
- 30 = 6x
- x = 30/6
- x = 5
d) the length and width are?
- The width is 5 cm and the length is twice the width, 5*2 = 10 cm
