6 0

Answer:

rational

Step-by-step explanation:

A rational number has the form

\frac{x}{y} \frac{a}{b} ← where a and b are integers

3.2 = \frac{32}{10} ← a rational number

Jonah collects rainwater in a large barrel that weighs 30 pounds. When there are 10 gallons of water in the barrel, the total we
Serjik [45]
The first thing we are going to do for this case is define variables.
 We have then:
 x: number of gallons of water
 y: total weight
 We then have an equation of the form:
 y-yo = m (x - xo)

 Where,
 m = (y2 - y1) / (x2 - x1)

 Substituting values:
 m = (196.8 - 113.4) / (20 - 10)

m = 8.34
 We choose an ordered pair:
 (xo, yo) = (10, 113.4)

 Substituting values:
 y-113.4 = 8.34 (x - 10)

 Rewriting:
 y = 8.34x - 83.4 + 113.4

y = 8.34x + 30
 Answer:
 
y = 8.34x + 30

Which number, when rounded to the nearest tenth, is 43.6? Options: A: 43.55 B: 43.657 C: 43.65 D: 43.549
weqwewe [10]

Answer:

A: 43.55

Step-by-step explanation:

Place value can be defined as the numerical value representing a digit owing to its position in a number. Some examples of the various place values used in representing each digit are tenths, hundredths, thousandths, unit, tens, hundreds, thousands etc.

For example, in the number 43.55;

  • The place value of 4 is tens.
  • The place value of 3 is units.
  • The place value of 5 is tenths.
  • The place value of 5 is hundredths.

Rounding up to the nearest tenth simply means to have 1 significant figure after the decimal point.

Therefore, 43.55 to the nearest tenth is 43.6

Equation parallel to y = 3x + 2 and passing through (1, 1)
Kisachek [45]

Answer:

y = 3x - 2

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = 3x + 2 ← is in slope- intercept form

with slope m = 3

Parallel lines have equal slopes, then

y = 3x + c ← is the partial equation

To find c substitute (1, 1) into the partial equation

1 = 3 + c ⇒ c = 1 - 3 = - 2

y = 3x - 2 ← equation of line

A man starts at a point A and walks 18 feet north. He then turns and walks due east at 18 feet per second. If a searchlight plac
34kurt

Answer:

1/10 per sec

Step-by-step explanation:

When he's walked x feet in the eastward direction, the angle Θ that the search light makes has tangent

tanΘ = x/18

Taking the derivative with respect to time

sec²Θ dΘ/dt = 1/18 dx/dt.

He's walking at a rate of 18 ft/sec, so dx/dt = 18.

After 3seconds,

Speed = distance/time

18ft/sec =distance/3secs

x = 18 ft/sec (3 sec)

= 54ft. At this moment

tanΘ = 54/18

= 3

sec²Θ = 1 + tan²Θ

1 + 3² = 1+9

= 10

So at this moment

10 dΘ/dt = (1/18ft) 18 ft/sec = 1

10dΘ/dt = 1

dΘ/dt = 1/10 per sec
