Every side of an isosceles triangle will always be the same

Answer:

x = 5

Step-by-step explanation:

Since the triangle is isosceles, the height is cutting the base in half.

That means the 2 right triangles have sides of 3 and 4.

The 3rd side is x. Using the Pythagorean Theorem, you get 5.

It is a 3-4-5 triple.

The previous response is wrong because it is isosceles, not equilateral

Factor the trinomial in to 2 sets of parentheses <br> 12a squared minus 13a minus 35

Juliette [100K]

It can't be factored because there are no 2 numbers that when you multiply you get 35 and when you add you get 13.

If 1 euro is priced at $1.25 and if 1 euro will also buy 88 Japanese yen (€1 = ¥88), in equilibrium, with no arbitrage opportuni

Alborosie

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.

Two mechanics worked on a car. The first mechanic charged $55 per hour, and the second mechanic charged $60 per hour. The mechan

Nady [450]

Answer:

15 and 5 hours.

Step-by-step explanation:

Call x the time taken by the first chap, and y the second.

$\left \{ {{x+y = 20 \atop {55x+60y=1125}} \right.$

Let's divide by 5 and play with the LHS of the first equation a bit:

$11x+ 11y +y = 225\\11(x+y)+y= 225$ we know how much x+y is ( first equation!) let's solve.

$11(20) +y = 225 \rightarrow y=5$ At this point it's easy to check that $x=15$
