In Exercise, evaluate each expression.<br> 643/4

Goshia [24]

Answer:

$\\ 64^{\frac{3}{4}} = 16\sqrt{2}$

Step-by-step explanation:

We need here to remember that:

$\\{(x^{a})}^{b} = x^{a * b}$

$\\{x^{a} * x^{b} = x^{a + b}$

Then,

$\\ 64^{\frac{3}{4}} = {(8^{2})}^{(\frac{3}{4})} = {{(2^{3})}^{2}}^\frac{3}{4}$

$\\ 64^{\frac{3}{4}} = {{2^{3}}^2}^\frac{3}{4} = 2^\frac{3*2*3}{4}$

$\\ 64^{\frac{3}{4}} = 2^\frac{2*3*3}{4} = 2^\frac{3*3}{2} = 2^\frac{9}{2}$

$\\ 64^{\frac{3}{4}} = 2^{\frac{9}{2}}$

Since $\\ \frac{9}{2} = \frac{4}{2} + \frac{4}{2} + \frac{1}{2}$

$\\ 64^{\frac{3}{4}} = 2^{\frac{9}{2}} = {2^{(\frac{4}{2} + \frac{4}{2} + \frac{1}{2})}$

$\\ 64^{\frac{3}{4}} = 2^{\frac{4}{2}} * 2^{\frac{4}{2}} * {2}^{\frac{1}{2}$

$\\ 64^{\frac{3}{4}} = 2^{2} * 2^{2} * {2}^{\frac{1}{2}$

$\\ 64^{\frac{3}{4}} = 4 * 4 * \sqrt{2} = 16 \sqrt{2}$

What is the best estimate for 591.3 divided by 29

Katena32 [7]

Answer:

about 20

Step-by-step explanation:

The numbers round to 600/30 = 20, which is a reasonable estimate.

You can refine this by doing the next step of long division:

29×20 = 580

Subtracting this from 591.3 give 11.3, so the fraction is ...

11.3/29 ≈ 10/30 = 1/3

A better estimate is 20 1/3.

28. How much plain yogurt will you need to make 2 1/2 dozen cookies? Show your work.

xxMikexx [17]

Answer:

$\frac{5}{6}$ cups

Step-by-step explanation:

Normally, when working with mixed numbers, I would prefer to turn them into improper fractions first before evaluating.

1 $\frac{1}{2}$ cookies --- $\frac{1}{2}$ cup plain yogurt

$\frac{3}{2}$ cookies --- $\frac{1}{2}$ cup plain yogurt

2 $\frac{1}{2}$ cookies --- ? cup plain yogurt

$\frac{5}{2}$ cookies --- $\frac{5}{3}$ × $\frac{1}{2}$ cup plain yogurt = $\frac{5}{6}$ cups plain yogurt

Find the value of x. <br>x = [?]

cricket20 [7]

X=2
As both triangles share a same side length of 5, and the angles are both 30degrees, assuming the triangles meet at the centre of the circle then both sides (x) must be the same.

The product of two consecutive integers is 420. An equation is written in standard form to solve for the smaller integer by fact

gladu [14]

Let the smaller integer be x.
The larger integer is x + 1.

x(x + 1) = 420

x^2 + x = 420

x^2 + x - 420 = 0

The constant is -420.
