liubo4ka [24]

Answer:

Required equation is: 25n = 875

Step-by-step explanation:

Let n be the number of minutes Jonathon read per day

Now

He read for 25 days and total 875 minutes

The equation will be:

$25n = 875$

We can solve this equation to find the number of minutes each day

Using Division property of Equality

$\frac{25n}{25} = \frac{875}{25}\\n = 35$

Hence,

Required equation is: 25n = 875

There are 100 bacteria in a jar. Every day, the number of bacteria increases 25%. In approximately how many days will there be 5

algol [13]

Use compound interest formula

$\\ \rm\Rrightarrow P(1+r/100)^t=500$

$\\ \rm\Rrightarrow 100(1+0.25)^t=500$

$\\ \rm\Rrightarrow (1.25)^t=5$

$\\ \rm\Rrightarrow log(1.25)^t=log5$

$\\ \rm\Rrightarrow tlog1.25=log5$

$\\ \rm\Rrightarrow t(0.097)=0.3$

$\\ \rm\Rrightarrow t=3.3\approx 3$

Calculate the slope of the line that contains the points: (2,-3) and (6,-3)

pshichka [43]

Answer:

Step-by-step explanation:

Slope (m) =

ΔY

ΔX

= 0

θ =

arctan( ΔY )

ΔX

= 0°

ΔX = 6 – 2 = 4

ΔY = -3 – -3 = 0

Distance (d) = √ΔX2 + ΔY2 = √16 = 4

Equation of the line:

y = 0x – 3

When x=0, y = -3
