If x is an odd number,write an expression for the odd number that comes directly before x.

1 answer:

3 0

Lets just say hypothetically that x=7. So to find the odd number before 7 we need to subtract a number. The odd before 7 is 5 which is 7-2. So by subtracting 2 from a odd value you get the odd value befire it so your equation is x-2

Evaluate each expression if x=3 y=12 and z=8

Rzqust [24]

Answer:

56/19

Step-by-step explanation:

∵ z = 8

∴ 4(8) + 8 - 6 =34

∵ x = 3

∴ 7z /(4 + 5x) = 7(8) ÷ (4 + 5 × 3) = 56 ÷ 19 = 56/19

∵ y = 12

∴ y² ÷ 3z = (12)² ÷ 3(8) = 144 ÷ 24 = 6

The cross section of a hopper for containing balls is shown.

svp [43]

ANSWER

$14 \: ft$

EXPLANATION

Let the top of the hopper be

$l \: ft$

Then, by the cosine rule,

${l}^{2} = {13}^{2} + {15}^{2} - 2(15)(13) \cos(59.5 \degree)$

We evaluate to get,

${l}^{2} = 169 + 225 - 390\cos(59.5 \degree)$

${l}^{2} = 394 - 197.94$

${l}^{2} = 196.06$
Take positive square root of both sides to get,

$l = \sqrt{196.06}$

$l = 14.00$
