What is 2 to the power of 4 over 3 equal to? (5 points)

ryzh [129]

Answer:

The answer is the option C

cube root of $16$

Step-by-step explanation:

Remember that

$a^{\frac{x}{y}} =\sqrt[y]{a^{x}}$

in this problem we have

$a^{\frac{x}{y}}=2^{\frac{4}{3}}$

therefore

$2^{\frac{4}{3}} =\sqrt[3]{2^{4}}=\sqrt[3]{16}$

Triangle ABC is similar to triangle PQR, as shown below:

natita [175]

Answer:

$\frac{q}{b}=\frac{r}{c}$

Step-by-step explanation:

Consider the options for this question are as follow,

$\frac{q}{c}=\frac{r}{b}$

$\frac{c}{p}=\frac{b}{a}$

$\frac{c}{a}=\frac{q}{r}$

$\frac{q}{b}=\frac{r}{c}$

Here, In triangles ABC and PQR,

AB = c, BC = a, AC = b, PQ = r, QR = p and PR = q,

Since,

$\traingle ABC\sim \triangle PQR$

We know that,

The corresponding sides of similar triangles are in same proportion,

Thus,

$\frac{AB}{PQ}=\frac{BC}{QR}=\frac{AC}{PR}$

$\frac{c}{r}=\frac{a}{p}=\frac{b}{q}$

$\frac{r}{c}=\frac{p}{a}=\frac{q}{b}$

$\implies \frac{q}{b}=\frac{r}{c}$

The hypotenuse of a right triangle is four times the length of one of the legs. The length of the other leg is 1500⎯⎯⎯⎯⎯⎯⎯⎯√ fee

Mrac [35]

Answer:

Step-by-step explanation:

So this is just playing with the pythagorean theorem

a^2 + b^2 = c^2 with a and b as legs and c as the hypotenuse.

Let's say a is equal to 1500 so then c is 4 times b

1500^2 + b^2 = (4b)^2 Now we just treat this like a normal algebraic expression

2,250,000 = 16b^2 - b^2

2,250,000 = 15b^2

150,000 = b^2

sqrt(150,000) = b

100sqrt(15) = b

You can check this now.

1500^2 + sqrt(150,000)^2 = c^2

sqrt(2,250,000 + 150,000) = c

sqrt(2,400,000) = c

400sqrt(15) = c Which fits the requirement of c = 4b

Ammar hikes 2 3/4 miles of nature trail in 1 hour15 minutes. How many miles of trail does am mar hike per hour

AleksandrR [38]

Change 1 hour 15 minutes = 1.25 hour because 15 ÷ 60 = 0.25 so we add 0.25 hour and change 2 3/4 to 2.75
Equation: $\frac{2.75}{1.25}= \frac{?}{1}$
Multiply 2.75 × 1 = 2.75 ÷ 1.25 = 2.2 miles
I'm pretty sure this is correct

Which system of inequalities is shown?

anzhelika [568]

Answer:

Option C

Step-by-step explanation:

from the graph: y<4

so option A and B are wrong.

also if we choose any points in the area, always x will be bigger than y. so x>y
