He bought a sandwich and orange juice, 8.49+2.49=10.98
Answer:
Step-by-step explanation:
Sin(30) / X = Sin(45) / 12
use algebra to isolate X
1 / X = [ Sin(45) / 12 ] / Sin(30)
flip both sides
X = Sin(30) / [Sin(45) /12 ]
invert the denominator on the right side
X = Sin(30) * 12/ Sin(45)
Do you know what Sin(30) is off the top of your head?
and also Sin(45) ?
these are worth remembering... and you can b/c they are just
sin(0) = 0/2
sin(30) = 1 / 2
sin(45) = /2
sin(60)= / 2
sin(90) = / 2 (aka 1)
note the numerators just counts up 0, 1, 2, 3, 4 :)
Cos works the same way but counts from 90° back to 0 but exactly like sin other wise, hence why Cos and Sin both = /2 at 45 °
anyway
X = 1 / 2 * 12/ /2
X = 3
A=3
B= 2
:) nice , huh
More than translates to addition (+)
is translates to equals (=)
n+4=12
Answer:
There are no values of x that make the equation true.
Step-by-step explanation:
3(x-2)=3x+7
3x-6=3x+7
3x-6+6=3x+7+6
3x=3x+13
Dviding 3x by 3x will equal 1, and 1 does not equal 13.
The mode of the given data is equal to bowls of spaghetti.
<u>Given the following data:</u>
- Quantity of sandwiches = 14.
<h3>What is mode?</h3>
In Mathematics, a mode can be defined as a statistical terminology that is used to denote the value that appears most often or repeatedly occurring in a given data set.
This ultimately implies that, a mode represents the value (number) with the highest frequency. In this exercise, the bowls of spaghetti represents the mode of the given data.
