Answer:

-4<4

Step-by-step explanation:

On the number like you can see that -4 is to the left of 4. This means that -4 is less than 4. All negative numbers must be smaller than positive numbers, therefore -4>4

The length of the rectangular tennis court at wimbledon is 6 feet longer than twice the width. if the court's perimeter is 240 f
KATRIN_1 [288]

Length (L): 2w + 6

width (w): w

Perimeter (P) = 2L + 2w

               240 = 2(2w + 6) + 2(w)

               240 = 4w + 12 + 2w

               240 = 6w + 12

               228 = 6w

                 38 = w

Length (L): 2w + 6   = 2(38) + 6   = 76 + 6   = 82

Answer: width = 38 ft, length = 82 ft

Given a point on a line and the equation of a parallel or perpendicular line, write the equation of the line in point-slope form
Arlecino [84]

Answer: y - 5 = 0(x - 1)

==================================================

Explanation:

Recall that point slope form in general is written as such

y - y1 = m(x - x1)

where,

m is the slope

(x1,y1) is the point the line goes through

The given equation y = 7 can be written as y = 0x+7. So we see that this line has a slope of m = 0

Plug m = 0 along with the given point (x1,y1) = (1,5) into the point slope equation and we get

y - y1 = m(x - x1)

y - 5 = 0(x - 1)

which is the final answer

note: the equation in bold can be rearranged and simplified to get y = 5; however your teacher seems to want the answer in point-slope form, so we leave it as such.

a solution of trioxonitrate (v) acid contained 0.67g in 100cm³. 31cm³ of this solution neutralized 25cm³ of a sodium trioxocarbo
FinnZ [79.3K]

Answer:

0.67 / 100 : 31^3 : 31^3 / 25cm^3

x 10

0.67 / 100 = 67 / 10000000  grams/cm  :  29791 / 15625 / 29791    

149253.731  : 0.52

divide by 1000

= 149.253731

= 149.3 kg

Ratio kg = 149.3 : 0.5

Step-by-step explanation:

Mole Ratio

The mole ratio compares the number of moles in a balanced equation.

This is the comparison between the coefficients in front of the chemical formulas.

If a formula lacks a coefficient, it is the same as saying there is 1 mole of that species.

Mole ratios are used to predict how much product a reaction forms or to determine how much reactant is needed to make a set amount of product.

Mole Ratio Units

Mole ratio units are either mole:mole or else it is a dimensionless number because the units cancel out. For example, it's fine to say a ratio of 3 moles of O2 to 1 mole of H2 is 3:1 or 3 mol O2: 1 mol H2.
