24 cents.

11/66= 6
4/x= 6
4•6= 24
(proportions)

hope this is clear :))

Answer:

b 48

Step-by-step explanation:

it says the sides a are 3 times larger so you are trying to find the perimeter of b so you do 144 divided by 3 since it is 3 times larger.

From a barrel of colored marbles you randomly select 7 blue, 5 yellow, 8 red, 4 green, and 6 purple marbles. Find the experiment

Green is 4 and Purple is 6 so you put it in a fraction by adding all of them and the just green and purple so 10/30 simplified is 1/3.

Which of the following equations is a constant function? y = x y = 5 x = 5

Mamont248 [21]

Answer:

Second Option

$y = 5$

Step-by-step explanation:

A constant function is one for which the range does not change regardless of the value of the domain.

$f (x_1) = f (x_2) = f (x_3) = m$

Where m is a constant.

The constant functions are horizontal lines parallel to the axis of the x

Note that

$y = x$ is not a constant function because the value of y changes when x changes.

x = 1, y = 1

x = 2 y = 2

$x = 5$ is not a constant function because the range of the function is not constant. $x = 5$ is a vertical line

$y = 5$ is a constant function, since for any of the value of x, the value of y will always be 5

<h2>○=> <u>Correct option</u> :</h2><h2> $\color{hotpink}\bold{ (a) \: 130}$ </h2><h3>○=> <u>Steps to derive correct option</u> :</h3>

Angle (p+7)° and angle (3p+1)° are a linear pair so their sum will be equal to 180°.

Which means :

$=\tt 3p + 1 + p + 7 = 180$

Let us solve that equation to find the value of p and the two angles :

$=\tt 3p + 1 + p + 7 = 180$

$=\tt 3p + p + 1 + 7 = 180$

$=\tt 4p + 8 = 180$

$= \tt4p = 180 - 8$

$= \tt4p = 172$

$=\tt p = \frac{172}{4}$

$\hookrightarrow \tt \color{plum}p = 43$

Thus, value of p = 43

Measure of angle (p+7)° :

$=\tt 43 + 7$

$\tt\color{plum}angle \: (p + 7)° =\tt 50°$

Measure of angle (3p+1)° :

$=\tt 43 \times 3 + 1$

$= \tt129 + 1$

$\tt\color{plum}angle \: (3p + 1)° = 130°$

Thus, the measure of the larger angle = 130°

Therefore, the correct option is <em>(a) 130</em>
