Answer:
8/27 yd³
Step-by-step explanation:
The equation for the volume of a cube of edge length s is V = s³.
If the edge length, s, is 2/3 yard, then the volume of this cube is:
V = (2/3 yd)³ = 8/27 yd³ (which corresponds to Answer C)
Answer:
The circumference is also 7 times larger
12 cm radius :2*pi*12= 75.43
12*7=84
84cm radius: 2*pi*84= 528
To check if its indeed 7 times larger: 528/75.43 and you'll get 7
If youre looking for the difference between the two: 528-75.43= 452.57
When there is a multiplication involving exponents, we need to evaluate the numbers and each variables separately. In this case, we have 5 and 4 as the numbers, and w and h for the variables.
When we multiply 5 and 4 we get:
For w, we have
,
,
. While we are multiplying the w's, we need to add the exponents together to get the final answer:
For h's, there are
,
,
. When we apply the same thing to h's, we get
For the final step, we need to write all of these together:
Answer:
x = 20/9
Step-by-step explanation:
We want to write out all of the mixed fractions into improper fraction form. So -2 and 1/9 becomes -19/9 and -4 and 1/3 becomes -13/3. Then we get (-19/9) - (-13/3). The two minus signs together means a positive/plus sign, so we get -19/9 + 13/3. In order to add, we want the denominator to be the same. A common denominator could be 9, so -19/9 + 13(3)/3(3) = -19/9 + 39/9 = 20/9, which is our final answer
