Answer:

d) 4 h 40 min

Step-by-step explanation:

11:35 am to 4:15 pm =

11:35 am to 12 pm + 12 pm to 4:15 pm

11:35 am to 12 pm = 25 min

12 pm to 4:15 pm = 4h15min

4 h 15 min + 25 min = 4 h 40 min

Algebra help?1?!?!/!??!?!?!?!?!?

zzz [600]

Hi,

Let's solve the equation step-by-step.

x−3x=2(4+x)

Step 1: Simplify both sides of the equation.

x−3x=2(4+x)

x+−3x=(2)(4)+(2)(x)(Distribute)

x+−3x=8+2x

(x+−3x)=2x+8(Combine Like Terms)

−2x=2x+8

Step 2: Subtract 2x from both sides.

−2x−2x=2x+8−2x

−4x=8

Step 3: Divide both sides by -4.

−4x/−4 = 8/−4

x=−2

Answer:

x=−2

Have a great day!

How many digits in hex do you need to represent integers up to 1, 000?

shepuryov [24]

You can convert 1000 to hex and see how many digits that requires:

$1000_{10}=(3\cdot16^2+14\cdot16+8)_{10}=3\mathrm e8_{16}$

So every integer below 1000 needs up to 3 digits.

Alternatively, we know that $16^2=256$ , and that $16^n$ requires $n+1$ digits in its hex representation (e.g. $16_{10}=10_{16}$ ). Taking the logarithm, we get $\log_{16}16^2=2$ , and adding 1 gives the number of digits needed to represent $16^2$ . Similarly,

$\lfloor\log_{16}1000\rfloor+1=3$

The vertices of an isosceles triangle are a(3, 6), b(7, 2), and c(4, 3). what is the equation of the triangle's line of symmetry

Paul [167]

Based on the calculations, the equation of the triangle's line of symmetry is equal to: B. y = x - 1.

<h3>How to determine the equation of the triangle's line of symmetry?</h3>

First of all, we would determine the midpoint where the line of symmetry passes through points A and B:

Midpoint at point A = (3 + 7)/2 = 10/2 = 5.

Midpoint at point B = (6 + 2)/2 = 8/2 = 4.

Point D = (5, 4)

Mathematically, the standard equation of a line is given by y = ax + b.

D(5, 4); 4 = 5a + b ....equation 1.

C(4, 3); 3 = 4a + b ....equation 2.

Subtracting eqn. 2 from eqn. 1, we have:

1 = a

Next, we would find the value of b:

4 = 5a + b

4 = 5(1) + b

b = 4 - 5

b = -1.

Therefore, the equation of the triangle's line of symmetry is given by:

y = ax + b

y = x(1) + (-1)

y = x - 1.

A radio station requires DJs to play 4 commercials for every 36 songs they play. What is the unit rate of songs to commercials?

elena55 [62]

Answer:

The correct answer for this question is that the unit rate is 5:1.

Step-by-step explanation:

We can work this out by simplifying down the 2 commercials to every 10 songs ration, so that 10:2 becomes 5:1. We can work this out by halving the original ratio to simplify it.
