Answer:

So the exchange rate is that each dollar is worth 70.4 yens.

Step-by-step explanation:

We have that:

1 euro is priced at $1.25

1 euro will also buy 88 Japanese yen

This also means that:

$1.25 is priced at 88 Japanese yen

How much is the cross rate between the yen and the dollar (yen per dollar exchange rate)?

How much yens is 1 dollar?

This can be solved by a simple rule of three.

$1.25 - 88 yen

$1 - x yen

1.25x = 88

x = \frac{88}{1.25}

x = 70.4

So the exchange rate is that each dollar is worth 70.4 yens.

Find the midpoint of CD if c= (9,2) d= (-7,-9)
Mrrafil [7]

To find the midpoint of a segment you need to use this equation:

(x1+x2/2, y1+y2/2) so if you plug in the numbers its...

9+(-7)/2, 2+(-9)/2

then solve to find x and y coordinate

x= 1 and y= -3.5

so the midpoint of CD is (1,-3.5)

Given that 3^x = 4^y = 12^z, show that z = (xy)/(x+y).
irinina [24]
3^{x} = 4^{y} = 12^{z}
3^{x} = 4^{y} = (4 \cdot 3)^{z}
3^{x} = 4^{y} = 4^{z} \cdot 3^{z}

\text{Let a } = 3^{x} = 4^{y} = 4^{z} \cdot 3^{z}
log_3a = x
log_4a = y
log_{(4 \cdot 3)}a = z

Using change of base:
x = \frac{lna}{ln3}
y = \frac{lna}{ln4}
z = \frac{lna}{ln(4 \cdot 3)}

ln3 = \frac{lna}{x}
ln4 = \frac{lna}{y}
ln(4 \cdot 3) = \frac{lna}{z}

Now, ln(4 · 3) = ln(4) + ln(3)

\frac{lna}{z} = \frac{lna}{x} + \frac{lna}{y}
\frac{1}{z} = \frac{1}{x} + \frac{1}{y}
\frac{1}{z} = \frac{x + y}{xy}

\therefore z = \frac{xy}{x + y}

Answer:

x=90

Step-by-step explanation:

So, since x-20 is the vertical angle directly near 70, we can say:

x-20=70.

if we solve x is 90.
