Answer:

The weight of the zinc in the metal bar was 50% of the weight of the metal bar .

Step-by-step explanation:

Weight of the metal bar ,M= 36 g

Weight of the zinc in the metal bar , m= 18 g

Percentage of zinc in the metal bar :

=\frac{m}{M}\times 100

=\frac{18 g}{36 g}\times 100=50\%

The weight of the zinc in the metal bar was 50% of the weight of the metal bar .

What is the third term of the sequence defined by the recursive rule f(1)=3 f(n)=f(n-1)+4

Need f(2):

f(2)=f(2-1)+4
f(2)=f(1)+4
f(2)=(3)+4=7

FIND f(3):
f(3)=f(3-1)+4
f(3)=f(2)+4
f(3)=(7)+4

write an equation of a line perpendicular to the givin equation using the given point givne (8,2); x = -4
MakcuM [25]

y=-x+10 is the equation of a line perpendicular to the givin equation using the given point given (8,2) and x = -4

<h3>What is Slope of Line?</h3>

The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.

The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.

The slope of line passing through two points (x₁, y₁) and (x₂, y₂) is

m=y₂-y₁/x₂-x₁

In the perpendicular lines the product of slopes will be -1

m1m2=-1

y=x+4 is the given line, it has slope of 1, so the perpendicular line will have slope -1.

The line is passing through (8,2)

2=-1(8)+b

2=-8+b

2+8=b

10=b

Hence, y=-x+10 is the equation of a line perpendicular to the givin equation using the given point given (8,2) and x = -4

The difference between 9 thirty-sevens and 8 thirty-sevens
romanna [79]
9 thirty-sevens will be 37 × 9 = 333
8 thirty-sevens will be 37 × 8 = 296
333 - 296 = 37

I don't think it is nine hundred thirty-seven and eight hundred thirty-seven. Word sevens has s.
