A) $\frac{2 \frac{1}{4}}{ \frac{1}{2}}$
b) $\frac{1}{2}$ • 2 = 1
so $\frac{9}{4}$ • 2 = $\frac{9}{2}$ cups (which is $4 \frac{1}{2}$ )

The following table lists the masses, in grams, of the nine planets (including dwarf planet Pluto). Use the data to choose the c

Marrrta [24]

The ratio between the masses of Jupiter and Venus is

$\dfrac{1.989\cdot 10^{30}}{4.869\cdot 10^{27}}$

We can separate the coefficient and the powers of ten:

$\dfrac{1.989\cdot 10^{30}}{4.869\cdot 10^{27}}=\dfrac{1.989}{4.869}\cdot \dfrac{10^{30}}{10^{27}}$

Use the exponent rule

$\dfrac{a^b}{a^c}=a^{b-c}$

to simplify the powers of 10:

$\dfrac{10^{30}}{10^{27}}=10^3$

So, the ratio is

$\dfrac{1.989}{4.869}\cdot 10^3\approx 0.4\cdot 10^3=400$

So, Jupiter has a mass that is approximately 400 times greater than Venus's.

Find the slope of the line that passes through the pair of points. F(–6, 8), P(–6, –5)

mariarad [96]

First, let's take a look at the formula to figure this out.

m = y2 - y1/x2 - x1

y2 would be -5, and y1 would be 8. -5 - 8 = -13.

x2 is -6, and x1 is also -6. -6 - -6 would be -12.

So, now we must divide -13 and -12, which results in 1 1/12.

Which expression is equivalent to 4x - (3x2 + x) + 5 - (2x2 + 1)?

creativ13 [48]

4x - (3x^2 + x) + 5 - (2x^2 + 1)

4x + x - 3x^2 - 2x^2 + 5 + 1

= 5x - 1x^2 + 6

Therefore the equivalent is 5x - 1x^2 + 6
