5x + 6y when x = 16, y = -9

Answer:

b. 6.2

Step-by-step explanation:

x =√18.2²-17.1² =√331.24- 292.41

= √38.83 = 6.2

533/100 then simplify

5 and 33/100

But that isn't an option and none of those options convert into 5.33, and I haven't been able to solve 3.75 repeating yet nor think it would convert into 5.33 anyhow. Please correct me if I'm solving this wrong.

Answer:

[tex]I(db)=320[/tex]

Step-by-step explanation:

Given

[tex]I(db)=10\log(\frac{I}{I_o})[/tex]

[tex]I = 10^{32}(I_o)[/tex]

Required

Determine [tex]I(dB)[/tex]

We have:

[tex]I(db)=10\log(\frac{I}{I_o})[/tex]

Substitute [tex]I = 10^8(I_o)[/tex]

[tex]I(db)=10\log(\frac{10^{32}(I_o)}{I_o})[/tex]

[tex]I(db)=10\log(10^{32})[/tex]

Apply law of logarithm

[tex]I(db)=10*32\log(10)[/tex]

[tex]\log(10) = 1[/tex]

So:

[tex]I(db)=10*32*1[/tex]

[tex]I(db)=320[/tex]

Answer: It's more likely it's a Tuesday

========================================================

Explanation:

The odds of it being a Tuesday is 1/7 since there's 1 day of the week that's Tuesday out of 7 total.

The odds of it being January is 1/12 because we have 1 month we want out of 12 total.

Now the question is: which fraction is larger?

For now, assume they are equal. We'll cross multiply like so

1/7 = 1/12

1*12 = 7*1

12 = 7

We get a false statement at the end, but we can fix things by replacing the equal sign with a greater than sign to get this new set of steps

1/7 > 1/12

1*12 > 7*1

12 > 7

which leads us to a true statement. Therefore, 1/7 is the larger fraction and the more likely event.

-----------------

Alternatively, you can use your calculator to find that:

Then for each decimal, move the decimal point 3 spots to the right. The values 0.143 and 0.083 become 143 and 83 respectively. We can see that 143 is larger, which means 0.143 is larger, and lastly 1/7 is larger. Think of it like a chain.

  c = 15 cm

Step-by-step explanation:

The congruent diagonals are perpendicular bisectors of each other, so ∆WVX is an isosceles right triangle. The length of c is √2 times the length WV, so is ...

  c = (√2)(10.6 cm) ≈ 15.0 cm

Answer:

2.75

Step-by-step explanation:

So to figure this out, lets start by converting it into a inproper fraction.

So we know that the whole number is 7, and the denominator is 16, so we need to multiply them together to make our fraction improper:

7*16

=

112

Now add the 9 from what we already had of the fraction:

112+9

=

121

So our improper fraction is:

121/16

Now we must find the square root.

So to find the square root of a fraction, you have to take the square root of both the numerator and the denominator.

The square root of 121 is 11. We know this because 121 is a perfect square, and 11*11 makes 121.

The square root of 16 is 4. We know this as well because 16 is also a perfect square, and 4*4 makes 16.

So the square root of 121/16 is now:

11/4

If you need to, you can convert this into a mixed fraction or a decimal.

4 goes into 11, 2 times with a remander of 3. So:

2 3/4.

3/4 is equivelent to 0.75, so this can also be:

2.75

This is your answer!

Answer:

The functions that represent this situation are A and C.

Step-by-step explanation:

A geometric sequence goes from one term to the next by always multiplying or dividing by the same value.

In geometric sequences, the ratio between consecutive terms is always the same. We call that ratio the common ratio.

This is the explicit formula for the geometric sequence whose first term is k and common ratio is r

The number line is an eighth number line so therefore it's 3/8.

Answer:

The diameter of a circle with an area of 100 square miles is 20/√π miles.

Step-by-step explanation:

Area =100 = πr^2.

diameter = d = 2r.

100 = πr^2.

100/π = r^2.

√(100/π) = r.

10/√π = r.

d = 2r.

d = 2 * 10/√π.

d = 20/√π

Answer:

None of the above

Answer:

$39.055

Step-by-step explanation:

100% + 7% = 107%

[tex]\frac{y}{36.5} :\frac{107}{100}[/tex]

y · 100 = 107 · 36.5

100y = 3905.5

100y ÷ 100 = 3905.5 ÷ 100

y = 39.055

Answer:

Step-by-step explanation:

a2+(48)2=

 502\,\,50^{2}502

Use the Pythagorean Theorem.

a2+2304=a^{2}+2304=a2+2304=

 2500\,\,25002500

Simplify.

−2304-2304\phantom{=}−2304=

 −2304\,\,-2304−2304

Subtract 2304 from both sides.

a2=a^{2}=a2=

 196\,\,196196

a2=\sqrt{a^{2}}=a2

​=

 ±196\,\,\pm\sqrt{196}±196

​

Square root both sides.

a=a=a=

 14\,\,1414

Simplify. Ignore negative root, as length must be positive.

Given:

Length of the rectangular prism = [tex]\dfrac{d-2}{3d-9}[/tex]

Width of the rectangular prism = [tex]\dfrac{4}{d-4}[/tex]

Height of the rectangular prism = [tex]\dfrac{2d-6}{2d-4}[/tex]

To find:

The volume of the rectangular prism.

Solution:

We know that the volume of rectangular prism is:

[tex]V=l\times w\times h[/tex]

Where, l is the length, w is the width and h is the height.

After substituting the given values, we get

[tex]V=\dfrac{d-2}{3d-9}\times \dfrac{4}{d-4}\times \dfrac{2d-6}{2d-4}[/tex]

[tex]V=\dfrac{d-2}{3(d-3)}\times \dfrac{4}{d-4}\times \dfrac{2(d-3)}{2(d-2)}[/tex]

[tex]V=\dfrac{(d-2)\times 4\times 2(d-3)}{3(d-3)\times (d-4)\times 2(d-2)}[/tex]

Cancel out the common factors.

[tex]V=\dfrac{4}{3\times (d-4)}[/tex]

[tex]V=\dfrac{4}{3(d-4)}[/tex]

[tex]V=\dfrac{4}{3d-12}[/tex]

Therefore, the correct option is C.

Answer:

[tex]18+6\sqrt{3}[/tex]

Step-by-step explanation:

In all 30-60-90 triangles, the side lengths are in the ratio [tex]x:x\sqrt{3}:2x[/tex], where [tex]2x[/tex] is the length of the hypotenuse, or longest side, of the triangle and [tex]x[/tex] is the length of the side that is directly opposite to the 30 degree angle.

The figure consists of three 30-60-90 right triangles (two inside a larger one). The side KL is marked as 6 meters and represents the side opposite to the 30 degree angle of the largest triangle (Since [tex]\angle L=90^{\circ}[/tex] and [tex]\angle K=60^{\circ}[/tex]). Therefore, the hypotenuse (longest side) of the triangle must be [tex]2\cdot 6=12[/tex] and the other leg must be [tex]6\sqrt{3}[/tex].

The perimeter of a polygon is equal to the sum of all the polygon's sides and therefore the perimeter of thing triangle is [tex]6+12+6\sqrt{3}=\boxed{18+6\sqrt{3}}[/tex]
