Answer:

2 pieces

Step-by-step explanation:

Given

Length = 1\frac{2}{3}m

Pieces = \frac{3}{4}m

Required

Calculate the number of pieces

To do this, we have to divide the length of the wood by the length of each piece.

Represent this with x

x= \frac{Length}{Pieces}

x= 1\frac{2}{3}/\frac{3}{4}

Convert mixed numbers to improper fraction

x= \frac{5}{3}/\frac{3}{4}

Change division to multiplication

x= \frac{5}{3}*\frac{4}{3}

x= \frac{20}{9}

x = 2.22

<em></em>x = 2<em> </em>

Help, I tried it, but I keep getting the wrong answers
Aneli [31]

Answer:

my answer would be that

x = 17.91cm

(i'm not sure about it either but it's worth a try) !!

Step-by-step explanation:

so first off, using the equation given,

" c² = a² + b² — 2ab cos C "

we substitute the values in as,

a = 16

b = 30

then for C is the angle given, which is 30°

so the equation is now,

c² = (16)² + (30)² — 2(16)(30) cos 30°

now, you solve the two squared numbers and the back equation, also known as " 2ab cos C " with your scientific calculator.

so it now equals to,

c² = 256 + 900 — 960(0.87)

c² = 320.8

at last, when you have " c² = 320.8 " ,

remember to square root the answer so you have a smaller value.

so,

c equals to

\sqrt{320.8}

your final answer for the x value will be 17.91

(i hope this helps!)

Which of the following is a non-linear equation?
Lana71 [14]

Answer:

iv ; xy + x/y = 3

Step-by-step explanation:

A non linear equation is one in which there is no product of two different variables or the same variable

What this mean is that we have the highest polynomial power as 1 or we simply have polynomials of degree 1

Looking at the given options, we can see the product xy

What this mean is that the polynomial is of degree 2 and that makes the equation a non linear as we have a polynomial of more than 1 degree

plz help me and I kindly ask that u show work if possible? Plz don't answer if u don't know how to do the problem. PLZ help
soldier1979 [14.2K]

part A is just simple multiplication
since there are 2 6 sided number cubes there are 36 possible outcomes(6 sides *6 sides)

Part B is a little trickier. First off, you must find how to get seven.
1. 1+6 and 6+1

2. 2+5 and 5+2

3.3+4 and 4+3

therefore there are six combinations

you put that number over the total combos and get 6/36 or 1/6.

Hope this helps!

What is the slope of the line that passes through (-4, 6) and (-6, 20)?
Hatshy [7]

Answer:

-7

Step-by-step explanation:

Since we have two points, we can use the slope formula

m = ( y2-y1)/(x2-x1)

    = ( 20-6)/(-6- -4)

    = ( 20-6)/ ( -6+4)

    = 14/-2

    = -7
