The volume of a rectangular prism can be found by multiplying the base area, B, times the height. If the volume of the prism is
PSYCHO15rus [73]

Answer:

Base (B) = /frac{15x² + 1 + 2}{x}

Step-by-step Explanation:

==>Given:

Dimensions of a rectangular prism are expressed as follow:

Volume (V) = 15x² + x + 2

Height (h) = x²

==>Required:

Expression of the Base area (B)

==>Solution:

Volume (V) = Base (B) × Height (h)

15x² + x + 2 = B × x²

Divide both sides by x²

\frac{15x² + x + 2}{x²} = B[tex]Base (B) = /frac{15x² + 1 + 2}{x}

Movies are on sale for 3/4 the original price. If the original price is $16, what is the sale price?
Nesterboy [21]

If the original price is 16, then 3/4 of 16 is 12.

$12


Dividing 16 by 4 (the denominator), you get 4. Then 4 x 3 (the numerator) is 12.

Make a conjecture about the next item in the sequence. 6, 9, 7, 10, 8?
inessss [21]

Answer:

"The next term should be 11"

Step-by-step explanation:

If we look closely at the sequence we can see:

second term is 3 more than previous

third term is 2 less than previous

fourth term is 3 more than previous

fifth term is 2 less than previous

We can see a pattern. To get next terms, we add 3, to get next to that, we subtract 2. It goes on like this.

Since 4th term to 5th term is "subtracting 2", logically 5th to 6th term (the term we are wanting) should be "add 3". So the term after 8 would be 11

The next term would be 11

Class A has 25 pupils and class B has 28 pupils. Both classes sit the same maths test. The mean score for class A is 69. The mea
il63 [147K]

Answer:

13

Step-by-step explanation:

Mean would mean average, which in this case is \frac{x+y}{2}

so your equation would look like \frac{69+x}{2}=41

Next multiply both sides by to clear the fraction 2*(\frac{69+x}{2})

to get 69+x=89

Subtract 69 from both sides 69+x=82\\-69   -69

you get x = 13
