Ierofanga [76]

First lets get the formula for a triangular prism

$v =( \frac{1}{2} bh)h$

First lets plug in our numbers

$v =( \frac{1}{2} \times 7 \times 4)8.5$

It really doesnt matter how you multiply everything, but you end up with 119cubic feet.

Simplify these expressions. a.2r+3+4r. b.8+3d+d. c.mn+ (-3mm)+6 d. 10s + (-10) + (-4s)

Maru [420]

Step-by-step explanation:

Combine like terms

a. 2r + 3 + 4r = (2r + 4r) + 3 = 6r + 3

b. 8 + 3d + d = (3d + d) + 8 = 4d + 8

c. mn + (-3mn) + 6 = (mn - 3mn) + 6 = -2mn + 6

d. 10s + (-10) + (-4s) = (10s - 4s) - 10 = 14s - 10

Terms are called "like terms" if they have the same variable part (the same letters in the same powers). Like terms differ at most coefficient.

The gcf of two numbers is 170. neither number is divisible by the other. what is the smallest these two numbers could be? (prime

ivanzaharov [21]

Answer:

$340$

Step-by-step explanation:

Given: GCF of two numbers is $170$ . neither number is divisible by the other.

To Find: smallest of these two number.

Solution:

As GCF of two numbers is $170$ , both number are divisible by $170$ .

Prime factor of $170$ $=2\times5\times17$

multiples of $170$ are $1\times2\times5\times17=170$

$2\times2\times5\times17=340$

$3\times2\times5\times17=510$

GCF of all three multiples is $170$ ,

Here $340$ and $510$ are the two multiples whose GCF is $170$ and neither is divisible by other

Hence the smallest of two is $340$ , the answer is $340$
