Answer:

Choice B is correct. (1/16)⁻⁴ = (16)⁴

Step-by-step explanation:

We have given the expression:

(1/16)⁻⁴

We have to find the equivalent expression from the following expressions.

We use the formula (b)⁻¹ = 1/b

(1/16)⁻⁴ = (16 / 1)⁴

(1/16)⁻⁴ = (16)⁴/(1)⁴

(1/16)⁻⁴ = (16)⁴

So, the choice B is correct.

Answer:

B) 16^4

Step-by-step explanation:

Given: (\frac{1}{16}) ^{-4}

Here we have to use the property a^-1 = 1 / a

Applying the property, we get

= (\frac{16}{1}) ^{4}

Now we can bring in the power of 4.

= 16^4 / 1^4

= 16^4 / 1

= 16^4

The answer is b) 16^4

Thank you.

Geometry question. please help ​

Answer:

The length of PQ is <u>18</u> feet.

The length of PR is <u>18</u> feet.

The length of QR is <u>24</u> feet.

Step-by-step explanation:

A way to set an equation up for this problem is:

\frac{4}{3}x+x+x=60

where x is the three lengths of the isosceles triangle, but the base QR is 4/3 the length of the other two congruent sides, length PQ and PR. The 60 represents the total length of the perimeter.

Then, solve for x from the equation, and you’ll get x=18. But your not done yet. Since the variable x in the equation stands for the sides of the isosceles triangle, so plug 18 into the equation and it should look like this:

\frac{4}{3}(18)+18+18=60

Don’t solve the whole equation, just solve the \frac{4}{3}(18) part of the equation, which is equal to 24. So the final equation is this:

24+18+18=60

Conclusion: 24 is the length of QR, and 18 is the length of PQ and PR. And they all equal 60, which is the perimeter. This is very true because the length of PQ and PR are the same (length 18), since it’s an isosceles triangle, and the length of QR is 4/3 the length of PQ and PR (4/3 of 18= 24).

Sorry for the long explanation.

But hope this helps and answers your question :)

2 right triangles have identical angle measures but different side lengths. The first triangle has side lengths of 6, 10, 8 and
lisabon 2012 [21]

Answer:

Dilation

Step-by-step explanation:

Given: The first triangle has side lengths of 6, 10, 8 and the second triangle has side lengths of 3, 5, 4 such that these two right triangles have identical angle measures but different side lengths.

To choose: the correct option

Dilation refers to a transformation when a figure is reduced or enlarged.

Each side of the large triangle is halved to get the small triangle.

So, Dilation transformation maps the large triangle onto the small triangle

Last question was wrong. Line l and line m are straight lines. What is the measure of angle y?
mafiozo [28]

y+43°= 180°( straight angle)

=>y= 180°-43°

=>y=137°

Ilang metro ang 1300 sentimetro?<br><br>a. 1metro<br>b. 13 metro<br>c. 130 metro​
Pie

Answer:

1300 cm = 13 m

Step-by-step explanation:

We need to find meters in 1300 cm.

We know that,

1 m = 100 cm

1 cm = (1/100) m

It means,

1300\ cm=\dfrac{1300}{100}\ m\\\\=13\ m

Hence, there are 13 m in 1300 cm.
