Answer:

1/4 ; $28.25

Step-by-step explanation:

Given the following :

Cost of stationeries:

Pencil:$1.20

Eraser:$1

Ruler:$0.50

Total : $169.50

Let total Stationeries purchased = t

Fraction of pencils = 1/3t

Remainder = t - 1/3 = 2/3t

Fraction of eraser = 5/8 of remainder

Thus ;

Fraction of eraser = 5/8 * (2/3)t= 10/24 = (5/12)t

Rest were ruler ;

(2/3)t - (5/12)t= (8 - 5)/12

= 3 / 12 = 1/4t

Fraction of rulers = 1/4

Amount spent on erasers:

(5/12) of the total cost of stationery

(5/12) * 169.50 = $70.625

B.) How much more did she spend on erasers than rulers

Amount spent on rulers :

(1/4) * $169.50 = $42.375

Take the difference :

$(70.625 - 42.375) = $28.25

Answer:

What is the Measure if what?

Step-by-step explanation:

GKW = 39°

PKG = 61°

PKW = 90°

PKF = 90°

FKM = 39°

PKM = 129°

WKF = 180°

WKM = 219°

2 (x – 4) = -5<br> How do I do this

DanielleElmas [232]

Step-by-step explanation:

your going to distribute the 2 to the x and the four your equation will then become (2x-8)=-5 you would then do the opposite of subtraction which is add so add +8 to the -8 and that cancels it out then you would +8 to the -5 and get 2x=3 then I'm confused from there hope that helps kinda

How to find the missing side of a triangle while only given angles and one side?

OLga [1]

Hi there!

Since you haven't given any numbers, I'll explain what you can do to figure this problem out. First, determine what side you have in relation to the angle (is it adjacent to the angle, it is opposite the angle, is it the hypotenuse?). Then, determine which trigonometry function to use (Sine = opposite/hypotenuse, Cosine = adjacent/hypotenuse, Tangent = opposite/adjacent). Check out the image below if you're confused. Anyway, you can use trigonometry to find the missing side of a triangle when only given angles and a side. All you have to do is plug in the numbers given and solve. (In the image, the O with a line through it represents the angle measurement that will be plugged in there.)

Hope this helps!! :)
If you're still confused or would like help solving a trigonometry problem, feel free to send me a message!
