Answer:
1. Either none (if you have to buy a whole pound), or 1/4 of a pound
2. 3 whole pounds or 3 and 1/4 pounds
Step-by-step explanation:
If $4 = 1 pound, then we know that $1 (which is 1/4 of $4), will let you by 1/4 pound of blueberries. Knowing this, we can simply:
Add up the one fourths
do 1/4 times $$
See how many times 4 goes into the number of dollars you have
Please correct me if I'm wrong :)
Answer:
<em>x = 24 </em>
Step-by-step explanation:
The corresponding sides of similar Δs are proportional.
ΔADE ~ ΔABC ⇒
=
=
AD = x + 8 ; DE = 8
AB = x ; BC = 6
=
⇔ 8x = 6(x + 8) ⇒ <em>x = 24</em>
Using this equation, f(3) = 23.
In order to find the value of f(3), we need to take the f(x) equation and put 3 everywhere we see x. Then we follow the order of operations to solve. So, let's start with the original.
f(x) = 2x^2 + 5sqrt(x - 2)
Now place 3 in for each x.
f(3) = 2(3)^2 + 5sqrt(3 - 2)
Now square the 3.
f(3) = 2(9) + 5 sqrt(3 - 2)
Do the subtraction inside of the parenthesis.
f(3) = 2(9) + 5sqrt(1)
Take the square root
f(3) = 2(9) + 5(1)
Multiply.
f(3) = 18 + 5
And add.
f(3) = 23
ANSWER: $432
STEP-BY-STEP EXPLANATION:
The cost of the tablet is $360
Then Tabitha has to pay 20% sales tax.
The tax is the prices times 20% plus the original price
360 ( 1+ 0.2)
360 (1.2)
=432
Answer:
l x w x h = 2,197
If l=w=h then it is a perfect cube.
The cube root of 2,197 is 13
Therefore, the cube is 13 x 13 x 13 inches.
