Answer:

<h2>Dolores is incorrect</h2>

Step-by-step explanation:

the surface area of the 1 ticket zone is (\pi 9^{2})-(\pi 6^{2}) which is ≈ 141 in ^3

the surface area of the 2 tickest zone is (\pi 6^{2})-(\pi 1^{2}) which is ≈ 110 in^3

141>110

the surface area of the 1 ticket zone is larger than the area of the two ticket zone so its not equal, so the one ticket zone has the highest probability

(05.06)A chocolate bar measures 40 mm wide, 80 mm long, and 5 and 1 over 2 mm high. Will’s Wrapping Company is making a wrapper
photoshop1234 [79]

Answer:

Will’s Wrapping Company needs 7,720 mm2 of paper to wrap the chocolate bar.

Step-by-step explanation:

we know that

The amount of paper needed to make the wrapper is equal to the surface area of the chocolate bar

The surface area of a rectangular prism (chocolate bar) is equal to

SA=2B+PH

where

B is the area of the base

P is the perimeter of the base

H is the height of he prism

In this problem we have

L=80\ mm\\W=5\frac{1}{2}\ mm=5.5\ mm\\H=40\ mm

<em>Find the area of the base</em>

B=LW=(80)(5.5)=440\ mm^2

<em>Find the perimeter of the base</em>

P=2(L+W)=2(80+5.5)=171\ mm

<em>Find the surface area</em>

SA=2(440)+171(40)\\SA=7,720\ mm^2

You have a shelf that holds 25 1/2 pounds. What is the most number of 1 1/4 pound books that the shelf can hold?​
patriot [66]

Answer:

20 books

Step-by-step explanation:

given that the shelf can hold 25 1/2 lbs (i.e 25.5 lbs), and that each book weighs 1 1/4 ln (i.e 1.25 lbs)

number of books which the shelf can hold

= weight that the shelf can hold ÷ weight of each book

= 25.5 ÷ 1.25

= 20.4 books

because having 0.4 of a book (i.e part of a book) would not be very feasable, we have to round the number of books down to the nearest whole number)

20.4 books rounded down to nearest whole number = 20 books (answer)

Help me pls
expeople1 [14]

I think you can find it graphically by points through a table you create like:

let x = 0, and find the value of y

for example for the first equation when we let x = 0 you find y = 6 and be in the form of (0,6) then draw them or you can let x = -2 or -3 , etc as you like

to be more accurate you can find 3 pionts and start graphing them

these two equations are straight lines and they will intersect in a point

In triangle NLM, point S is the centroid, QS = (3x – 5) cm, and NS = (4x) cm. What is NS? 5 cm 10 cm 20 cm 30 cm
son4ous [18]

Answer:

20 cm

Step-by-step explanation:

∵ S is the centroid of ΔNLM

∴ S divides NG at ratio 1 : 2 from the base

∴SQ = 1/2 NS

∴3x - 5 = 1/2 (4x)

∴3x - 5 = 2x

∴3x - 2x = 5

∴x = 5

∴ NS = 4 × 5 = 20 cm
