We gots 3 rectangles and 2 triangles

rectange area=length tiemsw dith
triangle=1/2 times base times h eight

rectangle left is
4 by 12 or 48 square inche

rectangle right is 9 by 4 or 36 squaer inches

back one is 15 by 4 or 60 square inches

triangles
there are 2 of them
12 by 9
2 times 1/2 times 12 times 9=108

add them all up

108+60+48+36=252 square inches

A standard six-sided die was rolled a number of times, and the results were recorded in the table below. Use this information to

Maru [420]

Answer:

<em></em> $P(Even) = 0.547$ <em></em>

<em></em>

Step-by-step explanation:

Given

$\begin{array}{ccccccc}{Sides} & {1} & {2} & {3} & {4} & {5} & {6} \ \\ {Freq} & {42} & {51} & {39} & {52} & {44} & {48} \ \end{array}$

Required

P(Even)

The even sides are: 2, 4, 6

So:

$P(Even) = P(2) + P(4) + P(6)$

This is then calculated as:

$P(Even) = \frac{n(2)}{Total} + \frac{n(4)}{Total} + \frac{n(6)}{Total}$

Replace n(2), n(4), n(6) with their frequencies

$P(Even) = \frac{51}{Total} + \frac{52}{Total} + \frac{48}{Total}$

The total frequency is:

$Total =42+51+39+52+44+48$

$Total =276$

So:

$P(Even) = \frac{51}{Total} + \frac{52}{Total} + \frac{48}{Total}$

$P(Even) = \frac{51}{276} + \frac{52}{276} + \frac{48}{276}$

Take LCM

$P(Even) = \frac{51+52+48}{276}$

$P(Even) = \frac{151}{276}$

<em></em> $P(Even) = 0.547$ <em> --- approximated</em>

7. The difference of Grandma Annie's age and twice Carl's is 22. Gran

OlgaM077 [116]

<h2>Systems of Equations Word Problems</h2>

To solve these questions, we can translate key words into operations:

<em>Difference</em> = subtract
<em>Twice</em> = double
<em>Less than</em> = subtract

<h2>Solving the Question</h2>

We're given:

Difference of Annie's age and twice Carl's age is 22
Annie's age is 13 less than 3 times Carl's age

There are two variables given two us: Annie's age and Carl's age.

Let Annie's age be equal to <em>x.</em>
Let Carl's age be equal to <em>y</em>.

Translate the given information into two equations:

Difference of Annie's age and twice Carl's age is 22
⇒ $x-2y=22$

Annie's age is 13 less than 3 times Carl's age
⇒ $x=3y-13$

Now, we can substitute the fist equation into the second one to solve for <em>y</em>:

$(3y-13)-2y=22\\3y-13-2y=22\\y-13=22\\y=35$

Now, substitute <em>y</em> back into the second equation to solve for <em>x</em>:

$x=3y-13\\x=3(35)-13\\x=105-13\\x=92$

<h2>Answer</h2>

Therefore, Grandma Annie is 92 years old.
