What is the surface area of the following triangular prism?


64.5 cm²
Surface area is the total area of all of the sides and faces of a three-dimensional figure.  To find the surface area, the area of each face is calculated and then add these areas together.

Is the equation x^9 – 5x^3 + 6 = 0 quadratic in form? Explain why or why not.


No, this equation is not quadratic. because the exponent of the first term is 9 while that of the second term is 3. The square of 3. If we are to square x3, we should only be getting x6 instead of x9. Therefore, the answer is NO.

this literally isn’t my answer btw

Answer: No

Step-by-step explanation:

It isn’t quadratic

Today, a bicycle rider rode her bike 5 1/2 miles. Yesterday, she rode 6 1/4 miles. The difference in length between the two rides is what fraction of the longer ride?





First we need to find the difference of the tow fractions. But to find it, we need to convert the mixed fraction to improper fraction so we can ease our calculation.

Remember that to convert a mixed fraction to an improper fraction, we just need to multiply the denominator of the fraction part by the whole number and add the result to the numerator of the fraction part; the denominator of the improper fraction will be the same denominator of the fraction part of the mixed fraction:

5(1)/(2) =((5*2)+1)/(2) =(10+1)/(2)=(11)/(2)

6(1)/(4) =((4*6)+1)/(4) =(24+1)/(4) =(25)/(4)

Now we can find the difference:

(25)/(4) -(11)/(2)

Remember that to add or subtract fractions, both fraction must have the same denominator, so we are multiplying both numerator and denominator of our second fraction by 2:

(25)/(4) -(11)/(2)*(2)/(2)

(25)/(4) -(22)/(4)=(25-22)/(4) =(3)/(4)

Now to find what fraction of our difference is to the longer ride, we just need to divide our difference by the longer ride:

((3)/(4))/(6(1)/(4) ) =((3)/(4))/((25)/(4) ) =(3)/(4) *(4)/(25) =(3)/(25)

We ca conclude the difference in length between the two rides is(3)/(25)of the longer ride.

Sally Ron and Jerry shared some large sandwiches that were the same size and cut into eighths Sally ate 5/8 sandwiches ron ate 7/8 sandwiches and Jerry ate 3/4 sandwiches who ate the most explain


The answer is Ron. First, you have to get a common denominator for the three fractions and the common denominator is 8. So 3/4 is equal to 6/8. Next, you compare the three fractions. 7/8 is larger than 5/8 because the numerator 7 is bigger than 5. 7/8 is bigger than 6/8 so 7/8 is larger than all the fractions. Therefore, Ron ate the most.
Ron, because if we see which fractions are largest


If 90 is 80 percent of the value what is the value


If 90 is 80% of the whole value, then 1/4 of 90 added to 90 will be the value, because 1/4 of 80% (which is 20%) added to 80% will give us 100%

90 + 12.5=102.5

At least, that's my take on it
