What is the distance between (5,2) and (-3,4) on a coordinate plane

maksim [4K]

$\bf \textit{distance between 2 points}\\ \quad \\
\begin{array}{lllll}
&x_1&y_1&x_2&y_2\\
% (a,b)
&({{ 5}}\quad ,&{{ 2}})\quad 
% (c,d)
&({{ -3}}\quad ,&{{ 4}})
\end{array}\qquad 
% distance value
d = \sqrt{({{ x_2}}-{{ x_1}})^2 + ({{ y_2}}-{{ y_1}})^2}
\\\\\\
d=\sqrt{[-3-5]^2+[4-2]^2}$

James bought 5 boxes of cookies and 2 cakes at the store for his party. The cakes cost $4 each and his total bill was $28.50, ho

maxonik [38]

Number of cookie boxes bought by James = 5
Number of cakes bought by James = 2
Cost of each cakes = $4
Total bill paid by James = $28.50
Let us assume the cost of the each boxes of cookies = x
Then
5x + (2 * 4) = 28.50
5x + 8 = 28.50
5x = 28.50 - 8
5x = 20.50
x = 20.50/5
= 4.10
So we can see from the above deduction that the cost of each boxes of cookies bought by James is $4.10

Joey had 40 words to study for a spelling quiz, but he only learned 10 of them. His teacher surprised the class by telling them

Natasha2012 [34]

Answer:

The probability of choosing a word randomly which is one of the words Joey learned = 1/4

Step-by-step explanation:

Total number of words to be memorized = 40 words

The number of words memorized by Joey = 10

Let E: Event of randomly choosing a word that Joey has learned.

P(E) = $\frac{\textrm{The total words learned by Joey}}{\textrm{Total Words in the quiz}}$

$\implies P(E) = \frac{10}{40} = \frac{1}{4}$

Hence, the probability of choosing a word randomly which is one of the words Joey learned = 1/4
