Brilliant_brown [7]3 years ago

Answer:

y=-2

Step-by-step explanation:

in other words, the question is asking

"six time what plus four equals 12?"

we know that 6 ⋅ 2 = 12

therefore if we plug the -2 into the Y we get

6(-2+4)=12

6(2)=12 or 6⋅2=12

therefore the answer is y=-2

If ab = 9 and a² + b² = 81, then (a+b)² = ?​
Andre45 [30]

Answer:

99

Step-by-step explanation:

Through some clever algebra, we can combine our first two equations using the fact that

(a+b)^2=a^2+2ab+b^2

We have the a² and the b² in the equation a^2+b^2=81, and we <em>almost </em>have a 2ab in the equation ab=9. To get that 2ab, we can simply double both sides of the first equation to get 2ab=18. From there, we'll add the first two equations together, giving us the summed equation

a^2+b^2+2ab=81+18\\a^2+2ab+b^2=99

And since (a+b)^2=a^2+2ab+b^2, we can equivalently say that

(a+b)^2=99

Part 6
Deffense [45]

Answer:

Part 1) The volume of each beam is 1,858.88\ ft^{3}

Part 2) You can fill 26\ beams

Part 3) Yes, the amount of sand left over is 1,669.12\ ft^{3}

Step-by-step explanation:

Part 1) What is the total volume of each beam?

The volume of a cylinder is equal to

V=\pi r^{2} h

we have

h=37\ ft

r=8/2=4\ ft ----> the radius is half the diameter

assume

\pi=3.14

substitute the values

V=(3.14)(4)^{2} (37)

V=1,858.88\ ft^{3}

Part 2) How many beams can you fill with this sand?

we know that

You are given a container with a 50,000 sq ft of sand for your beams

<em>Note</em> Is a 50,000 cubic foot  of sand instead of 50,000 sq ft of sand

Divide the total volume of sand by the volume of each beam to obtain the number of beams

50,000/1,858.88=26.9\ beams

Round down

26.9=26\ beams

Part 3) Will you have any sand left over? If so how much?

yes

50,000-26(1,858.88)=1,669.12\ ft^{3}

Ava and Jiao each swam a two-lap swimming race. Ava took 31.49 seconds to finish her first lap and 30.03 seconds to finish her s
omeli [17]

Answer:

Jiao's total swimming time is 59.73 seconds

Step-by-step explanation:

i) Ava took 31.49 seconds to finish her first lap.

ii) Ava took 30.03 seconds to finish her second lap.

iii) Therefore Ava took 31.49 + 30.03 = 61.49 seconds to complete her two laps.

iv) Jiao finished her two-lap swimming race 1.76 seconds before Ava.

v) Jiao's total swimming time = 61.49 - 1.76 = 59.73 seconds
