) If the pattern shown continues, how many black keys appear on a portable keyboard with 49 white keys? Suggestion: use equivale

andriy [413]

Answer:

35

Step-by-step explanation:

Here we see 5 black keys for every 7 white keys.

So the ratio is 5:7

If we need 49 white keys, find the amount we scale the original ratio by:

49/7 = 7

So we are scaling by a factor of 7.

The number of black keys would be 5 * the scale of 7. = 35

So there should be 35 black keys.

LK=<br> Help please asap thx so much

lora16 [44]

Answer:

LK = 4 $\sqrt{2}$

Step-by-step explanation:

given point J (4, 4 )

then LJ = 4 and JK = 4

using Pythagoras' identity in right triangle LJK

LK² = LJ² + JK² = 4² + 4² = 16 + 16 = 32 ( take square root of both sides )

LK = $\sqrt{32}$ = $\sqrt{16(2)}$ = $\sqrt{16}$ × $\sqrt{2}$ = 4 $\sqrt{2}$

Find the break-even point for the given cost and revenue equations. Round to the nearest whole unit. C = 20n + 134,000 R = 160n

Harman [31]

At break-even C = R so we have:-

20n + 134,000 = 160n

140n = 134,000

answer = 134,000 / 140 = 957
