How does the value of the 5 in 524.2 differ from the value of the 5 in 254.6??

mina [271]

In 524.2, 5 is in the hundreds place, so it stands for 500. In 254.6, 5 is in the tens place, so it stands for 50. You know what place it is in by how far to the left or right it is from the decimal point.

A group of 72 children completed a survey on what kind of sport they like. The choices were: Chess, Swimming, and Football. Ever

hichkok12 [17]

Answer:

$\dfrac{17}{72}$

Step-by-step explanation:

From the given information:

Total number of students, $n(U)=72$

The choices were: Chess(C), Swimming(S), and Football(F).

Everyone liked at least one sport except 7 kids, $n( C \cup F \cup S)'=7$

Chess is not an active sport; and

10 children liked Chess only, $n( C \cap F' \cap S')=10$

The probability that a randomly-chosen child from this group does not like active kinds of sport is the Probability that a student plays chess only or like no kind of sport at all.

$P( C \cup F \cup S)'+P(C \cap F' \cap S')=\dfrac{n( C \cup F \cup S)'+n(C \cap F' \cap S')}{n(U)} \\=\dfrac{10+7}{72} \\=\dfrac{17}{72}$

You are making 5 Autumn Classic bouquets for your friends. You have $610 to spend and want 24 flowers for each bouquet. Roses co

Sindrei [870]

There are 16 Roses , 2 Tulips , 6 Lilies in each Autumn Classic Bouquet.

<h3>Further explanation</h3>

Simultaneous Linear Equations could be solved by using several methods such as :

<em>Elimination Method</em>
<em>Substitution Method</em>
<em>Graph Method</em>

If we have two linear equations with 2 variables x and y , then we need to find the value of x and y that satisfying the two equations simultaneously.

Let us tackle the problem!

$\texttt{ }$

<em>Let For Each Bouguet:</em>

<em>Number of Roses = R</em>

<em>Number of Tulips = T</em>

<em>Number of Lilies = L</em>

$\texttt{ }$

<em>There are 24 flowers for each bouquet.</em>

$R + T + L = 24$ → <em>Equation 1</em>

$\texttt{ }$

<em>You have $610 to spend for 5 bouguets.</em>

<em>Roses cost $6 each, tulips cost $4 each, and lilies cost $3 each.</em>

$6R + 4T + 3L = 610 \div 5$

$6R + 4T + 3L = 122$ → <em>Equation 2</em>

$\texttt{ }$

<em>You want to have twice as many roses as the other 2 flowers combined in each bouquet.</em>

$R = 2 ( T + L )$ → <em>Equation 3</em>

$\texttt{ }$

<em>Equation 1 ↔ Equation 3:</em>

$R + T + L = 24$

$2 ( T + L ) + T + L = 24$

$3T + 3L = 24$

$T + L = 8$

$T = 8 - L$ → <em>Equation 4</em>

$\texttt{ }$

<em>Equation 4 ↔ Equation 3:</em>

$R = 2 ( T + L )$

$R = 2 ( 8 - L + L )$

$R = 2 ( 8 )$

$\boxed{R = 16}$

$\texttt{ }$

<em>Equation 2 ↔ Equation 4:</em>

$6R + 4T + 3L = 122$

$6(16) + 4(8 - L) + 3L = 122$

$96 + 32 - 4L + 3L = 122$

$L = 96 + 32 - 122$

$\boxed{L = 6}$

$\texttt{ }$

<em>Equation 4:</em>

$T = 8 - L$

$T = 8 - 6$

$\boxed{T = 2}$

$\texttt{ }$

<h2>Conclusion:</h2>

There are 16 Roses , 2 Tulips , 6 Lilies in each Autumn Classic Bouquet.

The width of the rectangle is 5x-4. The length of the rectangle is 5

drek231 [11]

Answer:

The area of the rectangle A = 25x² - 20x

Step-by-step explanation:

Given

The width of the rectangle = w = 5x - 4

The length of a rectangle = l = 5x

To determine

The area of the rectangle = ?

Using the Formula to determine the area of the rectangle

$A = wl$

substitute w = 5x - 4 and l = 5x in the formula

$A = (5x-4) (5x)$

Apply distributive law: a(b-c) = ab - ac

$=\left(5x\right)\cdot \:5x-\left(5x\right)\cdot \:4$

$=5x\left(5x\right)-4\left(5x\right)$

as 5x(5x) = 25x² and 4(5x) = 20x, so

$=25x^2-20x$

Therefore, the area of the rectangle A = 25x² - 20x
