Answer:

4. 4 tablets

5. no, 5 tablets

6. 19320 mg, 19.32 g

Step-by-step explanation:

4. 500 ÷ 125 = 4 tablets

5. a) no

b) 150 ÷ 30 = 5

you should be given 5 tablets

6. There are approximately 2.205 lbs in one kg.

Therefore, 142 lb = 142 ÷ 2.205 = 64.4 kg

300mg/kg/day

Therefore, number of mg per day = 300 x 64.4 = 19320 mg

b) As 1000mg = g

19320 ÷ 1000 = 19.32 g (nearest hundredth)

The midpoint of the line segment from upper p 1p1 to upper p 2p2 is left parenthesis negative 1 comma 5 right parenthesis(−1,5).

aliya0001 [1]

The coordinates of the second point are (2, 4).

The midpoint formula is:
$m=(\frac{x_1+x_2}{2},\frac{y_1+y_2}{2})$

Substituting our information, we have:

$(-1, 5)=(\frac{-4+x_2}{2},\frac{6+y_2}{2})$

This means that
$-1=\frac{-4+x_2}{2} \text{ and } 5=\frac{6+y_2}{2}$

Multiply both sides of both equations by 2 to cancel it:
$-1\times2=(\frac{-4+x_2}{2})\times2 \text { and } 5\times2=(\frac{6+y_2}{2})\times2
\\
\\-2=-4+x_2 \text { and } 10=6+y_2
\\-2+4=-4+x_2+4 \text { and } 10-6=6+y_2-6
\\2=x_2 \text{ and } 4=y_2$

This gives us our coordinates (2, 4)

| 10. Write an equation of a line that is parallel to

Alchen [17]

Answer:

see explanation

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 )

Rearrange - 3x + 4y = 5 into this form

Add 3x to both sides

4y = 3x + 5 ( divide all terms by 4 )

y = $\frac{3}{4}$ x + $\frac{5}{4}$ ← in slope- intercept form

with slope m = $\frac{3}{4}$

• Parallel lines have equal slopes, thus

y = $\frac{3}{4}$ x + c ← is the partial equation of the parallel line

To find c substitute (2. 1) into the partial equation

1 = $\frac{3}{2}$ + c ⇒ c = - $\frac{1}{2}$

y = $\frac{3}{4}$ x - $\frac{1}{2}$ ← equation of parallel line

The amount of force needed to keep a 0.1 kg basketball moving at a constant speed of 6 m/s on friction less ice is ____ Newtons

3241004551 [841]

Basketball has a mass of 0.1kg
m = 0.1 kg
The basket ball is moving at constant speed, this shows that it is not accelerating. So, acceleration is zero
a = 0m/s²
The constant speed is 6m/s
v = 6m/s
So, force to keep it moving with this constant speed can be calculated using Newton second law of motion
F = ma
F = m × 0
F = 0N
So, since the basket ball is moving at constant speed, then, the force need to keep the ball moving is 0N.
