Hal read 114 pages of his book during vacation. This was 60% of the book. How many pages does Hal have left to read?

Nadusha1986 [10]

Answer:

Step-by-step explanation:

so... 60% of his entire book is 114 pages...

let x represent his entire book

turn ur percent to a decimal

" of " means multiply and " is means equals

0.60x = 114...divide both sides by 0.60

x = 114/ 0.60

x = 190 pages left <===

Can someone help! I know the answer I just need step by step!

baherus [9]

Answer:

$4 \sqrt{2}$

Step-by-step explanation:

Rewrite 32 as the product of 16 and 2:

$\implies \sqrt{32}=\sqrt{16 \cdot 2$

Apply exponent rule $\sqrt{a \cdot b}=\sqrt{a}\sqrt{b}$

$\implies \sqrt{16 \cdot 2}=\sqrt{16}\sqrt{2}$

Rewrite 16 as 4²:

$\implies \sqrt{16}\sqrt{2}=\sqrt{4^2}\sqrt{2}$

Apply exponent rule $\sqrt{a^2}=a$

$\implies \sqrt{4^2}\sqrt{2}=4 \sqrt{2}$

Joe left the hospital at the same time as Eugene. They drove in opposite directions. Eugene drove at a speed of 70 km/h. After t

Gala2k [10]

If Joe and Eugene are travelling in opposite directions, their total distance is 360 km.

Eugene's speed = 70 km/hour

Let Joe's speed be = x

They each travel for 3 hours, so time = 3 hours

Distance = speed * time

$360=70(3)+x(3)$

$360=210+3x$

$3x=150$

$x=50$

Hence, Joe's speed is 50 km per hour.

$600 , 8% , 1 month find the simple interest

Vlad [161]

Answer:

Step-by-step explanation:

Simple interest = Principal *rate *time

S.I = P*r*t

Principal ; p = $600

rate ; r = 8% or 0.08 as a decimal

time; t = 1 month , however, convert this to years by dividing by 12;

t = 1 / 12

Next, plug in the numbers into the formula;

S.I = 600 *0.08* $\frac{1}{12}$

S.I = 4

Therefore simple interest in 1 month becomes $4
