Jordan’s family exchanged 250 dollars for 5000 pesos.
Effectus [21]

The number of dollars for one peso is 20 dollars.

Exchange rate is the rate at which one currency is exchanged for another currency.

In order to determine how many pesos can be exchanged for a dollar, the value of pesos would be divided by the amount of dollars exchanged.

Exchange rate = 5000 / 250 = 20 dollars

This means that 1 peso would be exchanged for 20 dollars.

A card is drawn from a well shuffled deck of 52 cards. Find the probability that the card is a red card or a 2.
tamaranim1 [39]
|\Omega|=52

There are 26 red cards and four 2's. But two 2's are red, so |A|=26+4-2=28

P(A)=\dfrac{28}{52}=\dfrac{7}{13}\approx54\%

If y varies directly as x and x=2 when y=−4, find y when x=−6.
kakasveta [241]

Answer:

Equation: x × -2 = y

Solution: y = 12

Step-by-step explanation:

if (x = 2) is (y = -4) then (x = 1) is (y = -2) so if (x = -6) is (y = 12) if we follow the equation [x × -2 = y] which was found using the first set of variables and dividing each by 2.

What is a scale factor?
Blababa [14]

Answer:

Here is some helpful information from my mini lessons.

Step-by-step explanation:

If two objects have the same shape, they are called "similar." When two figures are similar, the ratios of the lengths of their corresponding sides are equal. To determine if the triangles shown are similar, compare their corresponding sides. Here you'll learn that the ratio of the perimeters of similar figures is equal to their scale factor and that the ratio of their areas is equal to the square of their scale factor. If two polygons are similar, then the ratio of the lengths of any two corresponding sides is called the scale factor. This means that the ratio of all parts of a polygon is the same as the ratio of the sides.
