Answer:
He needs $1.64 he has to pay $26.64
Step-by-step explanation:
$25 is what Edwin has
5.95 x 2 = $11.19
$2.50 x 3 = $7.50
11.19 + 7.50 + 7.95 = $26.64
The answer is false because they are not emmediate
Hello!
You can use the equation to find the volume of a rectangular prism which is
V = whl
V is volume
w is width
h is height
l is length
1 1/2 = 1.5
Put in the values you know
120 = w * 8 * 1.5
Now you solve it algebraically
Divide both sides by 8
15 = w * 1.5
Divide both sides by 1.5
10 = w
The answer is 10 inches
Hope this helps!
Answer:
a. standard notation means in the number written in only number digits.
- to convert these multiply the two numbers given. FYI these are given in scientific notation, which is used so that numbers are easier to write.
<u>remember</u>: if the exponent is negative, you have move the decimal to the right. whereas, if the exponent is positive, you have to move the decimal to the left.
3 X 10^-4 --> move 4 places to the right.
answer - table salt: 0.0003
1.2 X 10^-2 --> move 2 places to the right.
answer - rock salt: 0.012
b. we know the standard notation of table salt is 0.003, so we simply multiply 40 by this.
answer - 0.0003 X 40 = 0.012
c. 0.012 = 0.012 (yes)
answer - yes the value i got in part B is equal to the mass of an average grain of rock salt. this shows that the mass of an average table salt is 1/40 times smaller than the mass of an average grain of rock salt.
-<em> i am not sure about the "what does this mean" part. you can put whatever there but i put what i think it could be. i think it would be based on what notes you took on class. </em>
