oksian1 [2.3K]

Answer: $53

Step-by-step explanation:

Given: Earning of Arthur in three weeks = $136

Let x be the money he earn in one more week.

If he needs at least $189 to buy the new coat that he wants for school.

Then it gives the inequality $136+x\geq 189$

Subtract 136 from both sides of the inequality, we get

$x\geq 189-136\\\Rightarrow\ x\geq 53$

Hence, Arthur must earn $ 53 in the next week.

Four speed skaters, Marco, Naim, Oliver, and Pedro, compete in a relay race where they all agree that Naim will be the last

Romashka [77]

Answer:

A = {MOPN. MPON, PMON, POMN)

Step-by-step explanation:

Complete Question

Four speed skaters, Marco, Naim, Oliver, and Pedro, compete in a relay race where they all agree that Naim will be the last skater. Then, they try to decide whether or not Oliver should be the first skater in the race.

Which subset, A, of the sample space shows the complement of the event in which Oliver is the first skater in the race?

A = {MOPN, PMON}

A = {OPMN, OMPN)

A = {MOPN,MPON, OPMN, POMN)

A = {MOPN. MPON, PMON, POMN)

So,

Naim would be last, that means, "N" must come last in all the sets. All of them have this, so that's good.

Now, they want "COMPLEMENT" of the set where Oliver is 1st. Complement is the "opposite" event, not in set/subset. So we disregard anyone where there is "O" in first place.

1st set have only 2 possibilities, so that's out.

2nd set have same, so that's out.

3rd set has "O" at first place in third sub, so that's out.

4th set DOESN'T have "O" in first place and has 4 subs, so this is the correct answer.

A = {MOPN. MPON, PMON, POMN) -- correct

The minimum length L of a highway sag curve can be computed by where θ 1 is the downhill grade in degrees (θ 1 < 0°), θ 2 is

8_murik_8 [283]

Answer:

The answer to the nearest foot is = 15 feet

Step-by-step explanation:

Solution

The first set taken is to Compute L for a 55-mph speed limit

Given that

L =(θ2 -θ1)/200 (h +S Tan ∝) =

= ( u + 5) 336²/200 (1.9 +336 tan 0.7°)

= 9° (336)²/200 (1.9 +336 tan 0.7°) = 14.7652094

= 15 feet { 9° = 9*π/180 = π/20}

Find the quotient. (3.683 × 104) (7.51 × 1012) What is the solution in scientific notation?

olasank [31]

Answer:

B

Step-by-step explanation:

$\frac{3.683 \times 10^4}{7.51 \times 10^{12}} \\=\frac{36.83 \times 10^3}{7.51 \times 10^{12}} \\=\frac{36.83}{7.51} \times 10^{3-12}\\ \approx 4.9041 \times 10^{-9}$
