36 is 0.9% of what number w?

Answers

Answer 1
Answer: We set up an equation: 36/?= 0.9/100

Cross multiply: 0.9*?= 36*100
⇒ ?= 36*100/0.9= 4000

36 is 0.9% of 4000.
Answer 2
Answer: 36 x 0.9 = answer

1.A line is parallel to the line 5x+y+4=0 Work out it's gradient (The answer is a whole number or decimal.)2.Another line is parallel to the line 3x+5y=15 Work out it's gradient. (The answer is a fraction)

5 points for each answer

Answers


If we arrange the equation of a line in standard form,
we can read its slope (gradient) directly.

1).                                            5x + y + 4  =       0

Subtract  4  from each side:    5x + y        =       -4

Subtract  5x  from each side:          y        = -5x - 4

The slope (gradient) of the line is  -5 .    

2).  Parallel lines have the same slope (gradient).
      First, find the slope (gradient) of the given line.

                                          3x + 5y =              15

Subtract  3x  from each side:    5y = -3    x + 15

Divide each side by  5 :              y = -3/5 x + 15

The slope (gradient) of the given line is  -3/5 .
Any line with a slope (gradient) of  -3/5  is parallel to this one.

Its equation will be         y = -3/5 x  +  any number.
 

the perimeter of the school gym is 200 feet.Christiana has 58 yards of streamers she wants to use as a border.Does she have enough to go around the whole gym

Answers

the answer is no because 58 yards = 174 ft, but the gym is 200 ft.
so she does not have enough to go around the whole. 1 yard = 3 ft

the answer is no just convert the measurements

The endpoints of a line segment are at the coordinates (–6, 3, 4) and (4, –1, 2). What is the midpoint of the segment?a
(–1, 1, 3)

b
(–2, 2, 6)

c
(–10, –2, 2)

d
(–5, –1, 1)

Answers

Answer:

( - 1,1,3 )

Step-by-step explanation:

Use the midpoint formula:

((x_1+x_2)/(2),(y_1+y_2)/(2), (z_1+z_2)/(2) )

We want to find the midpoint of the line

that has endpoints.

(( - 6+4)/(2),(3+ - 1)/(2), (4+2)/(2) )

We simplify to get;

(( - 2)/(2),(2)/(2), (6)/(2) )

This finally gives:

( - 1,1,3 )

mode- To find the mode, order the numbers lowest to highest and see which number appears the most often.

mean-To find the mean, add all the numbers together then divide by the number of numbers.

median-To find the median, order the numbers and see which one is in the middle of the list.
