2/4 = x/15
*cross multiply*
2(15) = 4(x)
30 = 4x
7.5 = x

Hope this helps!

Dollar is worth three and 3 1/2 kruneros. What is the value of 43 3/4 kruneros?

Korvikt [17]

Question:

One dollar is worth 3 1/2 kruneros. What is the value of 43 3/4 kruneros?

Answer:

The value of $43\frac{3}{4}$ kruneros is 12.5 dollars

Solution:

Given that,

Dollar is worth three and 3 1/2 kruneros

Which means,

$1 \text{ dollar } = 3\frac{1}{2} \text{ kruneros }\\\\1 \text{ dollar } = 3.5 \text{ kruneros }$

We have to find the value of $43\frac{3}{4}$ kruneros

Let us convert the mixed fractions to improper fractions

Multiply the whole number part by the fraction's denominator.

Add that to the numerator.

Then write the result on top of the denominator.

$43\frac{3}{4} = \frac{43 \times 4 + 3}{4} = \frac{175}{4} = 43.75$

So we have to find the value of 43.75 kruneros

Let "x" be the value of 43.75 kruneros

Then,

1 dollar = 3.5 kruneros

x dollar = 43.75 kruneros

This forms a proportion and we can solve the sum by cross multiply

$1 \times 43.75 = x \times 3.5\\\\x = \frac{43.75}{3.5}\\\\x = 12.5$

Thus value of $43\frac{3}{4}$ kruneros is 12.5 dollars

What is the approximate Probability of drawing a Black OR Face Card from a standard deck of shuffled cards?

JulijaS [17]

Answer:

0.73

Step-by-step explanation:

Number of cards in a standard deck = 52

Number of black cards = 26

Number of face cards = 12

Probability of drawing either a black or face card

Probability = required outcome / Total possible outcomes

P(drawing a black card or face card) = (number of black cards / total card) + (number of face cards / total cards)

= 26/52 + 12 /52

= 0.5 + 0.2307692

= 0.73

Which applies the power of a power rule properly to simplify the expression (710)5? (710)5= 710 ÷ 5 = 72 (710)5= 710 - 5 = 75 (7

Sever21 [200]

We are asked in this problem to determine the condensed form of the expression (7^10)^5. we apply here the power rule in which exponents are multiplied to each other to get the expanded form. In this case, we multiply 10 by 5 that is a total of 50. hence the answer to this problem is D. 7^50
