<u>y = 25</u>

Step-by-step explanation:

<u>=> 115 = y + 90 {exterior angle of triangle is equal to the sum of its opposite two interior angles}</u>

<u>=> 115 = y + 90 </u>

<u>=> 115-90 =y</u>

<u>=> 115 = y + 90</u>

<u>=> 115-90 =</u><u>y</u>

<u>=> y = 25</u>

Answer:

x= 180°-115°

= 65° ( adjacent angles in a straight line)

y= 180°-90°-65°

= 25° ( angle sum of a triangle)

The cost of 5 pounds of boudin is $26.What is the constant of proportionality that relates the cost in dollars,y, to the number
Ymorist [56]

Given :

The cost of 5 pounds of boudin is $26.

To Find :

The constant of proportionality that relates the cost in dollars y, to the number of pounds of boudin x .

Solution :

Price per boudin in terms of x and y is :

P=\dfrac{y}{x}

Price per boudin by given data :

P=\dfrac{26}{5}

So,

\dfrac{y}{x}=\dfrac{26}{5}\\\\y = \dfrac{26}{5}x

Therefore, the constant of proportionality is \dfrac{26}{5}.

Hence, this is the required solution.

What is 5/10 + 8/100
Greeley [361]

Answer:

\frac{29}{50}

Step-by-step explanation:

We have two fractions and are being asked to add them both.

5/10 and 8/100 don't have the fractions, but 5/10 can be simplified to 1/2, meaning that to make the same denominator, we have to find the half of 100, which would be 50. Now turn the fraction into 50/100.

50/100 + 8/100

58/100

This can be simplifed :

\frac{58/2}{100/2}

\frac{29}{50}

serg [7]

Answer:

13 degrees

Step-by-step explanation:

Because of the alternate interior angles, I know that angle EB is also 77. Now, knowing that it's a right angle, I can subtract 77 from 90 to get 13.

PROBLEM SOLVING A ski shop sells skis with lengths ranging from 150 centimeters to 220 centimeters. The shop says the length of
grin007 [14]

Answer:

h > 189.66\ cm  or  h< 129.31\ cm

Step-by-step explanation:

Let

h ----> a skier's height in centimeters

we know that

A ski shop sells skis with lengths ranging from 150 centimeters to 220 centimeters

The interval of the skis is -----> [150,220]

The compound inequality that represents the heights (in centimeters) of skiers the shop does not provide skis is

1.16h > 220\ cm ----> inequality A

or

1.16h< 150\ cm ----> inequality B

<em>Solve inequality A</em>

1.16h > 220\ cm

Divide by 1.16 both sides

h > 189.66\ cm

<em>Solve inequality B</em>

1.16h< 150\ cm

Divide by 1.16 both sides

h< 129.31\ cm

therefore

h > 189.66\ cm  or  h< 129.31\ cm
