Crazy boy [7]

Answer:

see explanation

Step-by-step explanation:

∠ YXW = ∠ ZXV ( vertically opposite angles ) , so

4a + 15 = 2a + 65 ( subtract 2a from both sides )

2a + 15 = 65 ( subtract 15 from both sides )

2a = 50 ( divide both sides by 2 )

a = 25

Then

(7)

∠ ZXV = 2a + 65 = 2(25) + 65 = 50 + 65 = 115°

(8)

∠ YXW = ∠ ZXV = 115°

∠ ZXY and ∠ ZXV are adjacent angles and sum to 180° , that is

(9)

∠ ZXY = 180° - 115° = 65°

(10)

∠ VXW = ∠ ZXY = 65° ( vertically opposite angles

An engineer is designing a fountain that shoots out drops of water. The nozzle from which the water is launched is 3 meters abov
Hoochie [10]

Answer:

After 3 seconds

Step-by-step explanation:

Given

h(t) = -5t^2 + 14t + 3

Required

Time the drop will hit the ground

When the drop hits the ground,

h(t) = 0

So, we have:

0 = -5t^2 + 14t + 3

Rewrite as:

5t^2 - 14t - 3 = 0

Expand

5t^2 + t - 15t - 3 = 0

Factorize

t(5t + 1) -3(5t + 1) = 0

Factor out 5t + 1

(t -3)(5t + 1) = 0

Split

t -3 = 0 or 5t + 1 = 0

Solve for t

t = 3 or 5t = -1

Time cannot be negative.

So:

t = 3

Apples are sold in bags of four that cost $5, or bags of six that costs $7 per bag. What is the smallest cost at which you can b
babunello [35]
STEP 1:
BAGS OF FOUR
find number of bags needed to total 74 apples

= 74 ÷ 4 apples/bag
= 18.5 bags

*must round up to 19 bags because we cannot buy a partial bag

STEP 2:
BAGS OF FOUR
calculate price of 19 bags of 4 apples per bag

= 19 bags * $5/bag
= $95 for 19 bags of 4 apples/bag

STEP 3:
BAGS OF SIX
find number of bags needed to total 74 apples

= 74 ÷ 6 apples per bag
= 12.3333 bags needed

*must round up to 13 bags because we cannot buy a partial bag

STEP 4:
BAGS OF SIX

calculate price of 13 bags of 6 apples per bag

= 13 bags * $7 per bag
= $91 for 13 bags of 6 apples/bag


ANSWER: The smallest cost to buy 74 apples is $91.

Hope this helps! :)
