i just divide

Answer: 9.043 centimeters/grams

Step-by-step explanation:

All you have to do it divide!

Answer:

x<-5.5   or x<-11/2

Step-by-step explanation:

2(4x+1)<3(2x-3)

1. First we need to expand the brackets

8x+2<6x-9

2. get the x on one side so we would -6x and -2 on each side

2x<-11

3. divide by 2 on each side as we want to get the value of x which gives

x<-11/2

the fraction can also be written as a decimal

x<-5.5

4) so, the final answer is

x<-5.5 or <-11/2

The volume of the remaining solid correct to 2 decimal places is 3634.60 m³

From the question, we are to determine the volume of the remaining solid

Volume of the remaining solid = Volume of the larger prism - Volume of the rectangular prisms carved out

First, we will determine the volume of the larger prism

Volume of the larger prism = 17 × 17 × 17

Volume of the larger prism = 4913 m³

Now, we will determine the volume of one of the rectangular prism that was carved out

Volume = 4 × 9.4 × 17

Volume = 639.2 m³

∴ Volume of the two identical holes carved out = 2 × 639.2 m³

= 1278.4 m³

Thus,

Volume of the remaining solid = 4913 m³ - 1278.4 m³

Volume of the remaining solid = 3634.60 m³

Usual selling price of a pair of shoes is $68 with discount 40% and sales tax 6% then total price of shoes including tax is equal to $43.248.

As given in the question,

Given that:

Usual selling price of shoes = $68

Discount on shoes =40%

Discounts an amount or percentage from something that they are selling, they take the amount or percentage off the usual price.

so, remove 40% from the price and you have left 60%

reduced price = 60% of $68

                         =60/100 * 68 = $40.8

Sales tax is 6% of reduced price= 6% of $40.8

                                           =$2.448 upto 3 decimal digits

Now , price including tax =$40.8+$2.448 =$43.248

Hence, total price including tax= $43.248

Therefore, usual selling price of a pair of shoes is $68 with discount 40% and sales tax 6% then total price of shoes including tax is equal to $43.248.

Step-by-step explanation: Equation of line in slope intercept form is represented by,. y= mx+c —-(1). Given that the line p passes through A (- 2, 4) and has a slope m= -1/2.

It will take the bottle of maple syrup 3 hours 45 minutes to reach  20° C from  –16° C.

given data

the bottle temperature will go up a steady 9.6° C every hour

freezer temperature  = –16° C

final temperature = 20° C

The temperature rise from –16° C to 20° C

from –16° C to 0° C = 16° C

from 0° C to 20° C = 20° C

adding both increments gives = 20 + 16 = 36° C

if every hour we have 9.6° C then how many hours will give 36° C

1 hour = 9.6° C

? hour = 36° C

we cross multiply to have

= 36 * 1 / 9.6

= 3.75

This is 3 hours then a fraction of some minutes, the fraction is gotten by

0.75 * 60 = 45

Therefore the time to reach 20° C is 3 hours 45 minutes

Based on the equation of the line that is parallel to the first line, the equation of the line in slope-intercept form is y = 3/4x - 6³/₄

First, find the slope of 3x + 4y = 7:
( 3x + 4y = 7) x 1/4

3/4x + y = 7/4

The slope is therefore 3/4x.

Lines that are parallel to each other have the same slope. You can therefore use this slope to find the formula of the other line by first solving for the y-intercept:
y = Slope(x) + y-intercept

-9 = 3/4(-3) + y-intercept

y-intercept = -6³/₄

The equation of the line is:

y = 3/4x - 6³/₄

Since the population increases at a rate proportional to the current number of people, the population will be three times of its initial population after 14.27 years.

The population of a community increases at a rate proportional to the number of people present at time t, means:

dP/dt = kP

where k is a constant.

Rearrange it:

(1/P) dP = k dt

Take the integral:

∫ (1/P) dP = ∫ k dt

ln P = kt + C, where C is a constant

Substitute t = 0, from the problem, it is known that P(t = 0) = P₀

Hence,

P(t) = P₀. e^(kt)

The population doubles after 9 years, means if we substitute t = 9

P(9) = P₀. e^(9k)

2P₀ = P₀. e^(9k)

2 = e^(9k)

Take the natural logarithmic:

ln 2 = 9k

k = (ln 2)/9 = 0.077

When the population grows to triple, it means P(t) = 3P₀

3P₀ = P₀. e^(kt)

ln 3 = kt

ln 3 = 0.077 t

t = (ln 3)/0.077 = 14.27 years.

Hence, the population will be three times of its initial population after 14.27 years.
