Answer:

the answer for this is option C 4x/x+5

Answer:

x + 5/ x - 3

Step-by-step explanation:

expand 4x²+16 to get:

4x(x+4)

then multiply by the reciprocal to cancel the 4x(x+4) leaving you with x + 5/ x - 3

Answer:

she bought 70 shares of the $15 shares

she bought 20 shares of the $20 shares

Step-by-step explanation:

this would be solved using simultaneous equation

let a = $15 shares

b = 20 shares

a + b = 90   equation 1

15a + 20b = 1450  equation 2

Multiply  equation 1  by 15

15a + 15b = 1350  equation 3

subtract  equation 3 from  equation 2

5b = 100

b = 20

substitute for b in  equation 1

20 + a = 90

a = 70

Answer:

Step-by-step explanation:

square of 15 + square of x = square of 21

225 + square of x = 441

441 - 225 = 216

x = 216

Answer:

Linear Exponential Decay.

Step-by-step explanation:

It is linear exponential decay,

it is decreasing by -7,

everytime x goes up 1, y goes down -7,

this line has a slope of -7/1.

Slope: -7x

y-intercept: (0,2)

The answer is 3.93 hours. This is because in one hour there are 60 minutes so you would need to divide your number 236 by 60 and you should end up with 3.9333, which rounded to would just be 3.93 hours in total.

Answer:

Amount they ate is 6/8 or 3/4 of the pizza

Amount left over is 2/8 or 1/4 of the pizza.

Step-by-step explanation:

your family at 6 out of 8 pieces and simplified thats 3/4 if you divide both by 2

so the pieces left over would be 2 pieces or 2 out of the 8 pieces are left over.

making your fraction 2/8

Now you simplify and you can divided both 2 and 8 by 2

Making your other fraction 1/4

Answer:

The probability is the pvalue of [tex]Z = X - \mu[/tex], in which X is the number of minutes we want to find the probability of time being less of, and [tex]\mu[/tex] is the mean.

Step-by-step explanation:

Normal Probability Distribution:

Problems of normal distributions can be solved using the z-score formula.

In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.

Standard deviation of 1 minute.

This means that [tex]\sigma = 1[/tex]

Find the probability that a randomly selected college student will find a parking spot in the library parking lot in less than minutes.?

This is the pvalue of Z for X. So

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{X - \mu}{1}[/tex]

[tex]Z = X - \mu[/tex]

The probability is the pvalue of [tex]Z = X - \mu[/tex], in which X is the number of minutes we want to find the probability of time being less of, and [tex]\mu[/tex] is the mean.

Answer:

V = 2832 m3 only if that 1 2 is a 12 if that is not a 12 it is wrong

Step-by-step explanation:

Answer:

6 m

Step-by-step explanation:

36 m^2 = bh/2

36·2 = bh/2·2

72 = bh

72 = 12·6

check

36 m^2 = 12·6/2

36 = 36

Answer:

60

Step-by-step explanation:

Given,

x = 2

y = 3

3x^y + 4y^x

= 3 ( 2 )^3 + 4 ( 3 )^2

= 3 ( 8 ) + 4 ( 9 )

= 24 + 36

= 60

Answer:

Car A: 8 minutes

Car B: 6.67 minutes

Step-by-step explanation:

Car A: 60km evrery hour so,

1 km every minute, so he will be in 8km in 8 minutes.

Car B: 72km per hour so,

72/60 = 1.2 = 1.2 km per minute.

8/1.2 = 6.6666666666667 which is about 6.67 to the nearest hundredth.

Answer:

40 min

Step-by-step explanation:

Car A is traveling at 1 km/min (60/60)

Car B is traveling at 1.2 km/min (72/60)

Car B gains .2km on Car A for every minute they drive.

8km/.2 = 40

Answer:

10ft

Step-by-step explanation:

Let assume the volume of the box be 480ft^3

Required

height h

Volume of the box = length * width * height

Substitute

480 = 8 * 6 * h

480 = 48 * h

h = 480/48

h = 10ft

Hence the height of the box if the volume of 480ft^3 is 10ft
