Answer:

18

Step-by-step explanation:

.5 is 5 4 and below round down 5 and up round up

Answer:

A. The balloon is at its initial height

B. The boxer is 0 pounds from her starter weight

C. The company's size is smaller

Step-by-step explanation:

For A, -30+30 is equal to 0 so its gonna be the same height it was before.

For B, Gaining 7 pounds and losing 7 pounds means you are neither bitter or smaller. (-7+7=0)

For C, Losing 15 employees and gaining none means that there are less than there were previous meaning the company is now smaller.

Hope this helps.

Answer:

$160.75

Step-by-step explanation:

Step one:

given data

The resort charges $20.75 per hour in addition to a $35 deposit to rent a snowboard

The time spent from 8:30 am to 12:30 pm = 4hours

Step two:

Let the number of hours be and the total cost be y

Now the expression for the situation can be represented as

y= 20.75+35x

for x= 4

y=20.75+35(4)

y=20.75+140

y=160.75

Step-by-step explanation:

let 'x' = amount of time in REM sleep

Answer:

1.4[tex]\leq[/tex] x [tex]\leq[/tex] 1.6

Step-by-step explanation:

You can start off by writing the inequality that 7(.20) is less than/equal to x which is less than/equal to 8(.20). Then, you just multiply the numbers and you have the 20% that you spend in REM sleep.

Answer:

the second one or B

$0.15+$40.00=$58.00

it is this because the number of mins is .15 cent each min

Answer:

A

A

Step-by-step explanation:

8) because of the rules of angles we know that all angles found on a line are equal to 180 degrees, and all angles opposite one another are equal. because of this A is not possible. 90 and 40 do not add up to 180 degrees, and are not equivalent to each other.

9) using the same rules as above, we know that the two angles have to add up to 180 degrees (they can't be equal this time). A is not possible.

Answer:

It’s +16

Step-by-step explanation:

Given:

Current population = x

The population of a city is expected to decrease by 6% next year.

To find:

The expression that represents the expected population next year. ​

Solution:

We have,

Current population = x

Decrease rate = 6%.

Expected population next year = Current population - 6% of Current population

                                                    =[tex]x-\dfrac{6}{100}x[/tex]

                                                    =[tex]x-0.06x[/tex]

                                                    =[tex]0.94x[/tex]

Therefore, the expression for the expected population next year is 0.94x.

Hi, this expression is not solvable because we can just literally substitute anything with x. You cannot solve an expression, unless given a value. However,  you can solve an equation. In this case, it is an expression.

13.22%

Step-by-step explanation:

Answer:

V2 = 8571.43L

Step-by-step explanation:

To solve for the V2, We can use V2 = P1V1 / P2

= 1.0 atm × 12,000 L / 1.4 atm    

 = 12,000 L / 1.4 atm

= 8571.43 L

Answer: Graph B

Step-by-step explanation:

The unit price for the strawberries is:

= 1.5 / 2

= $0.75 per pound

Graph B is the right graph as it uses a unit price of $0.75 per pound for strawberry price. This is why it has points of the graph that mirror the friends purchases such as (2, 1.5) , (3, 2.5) and (4, 3).

5 is the slope

Step-by-Step Explanation:

(10, 50) x1 and y1

(20, 100) x2 and y2

[tex]\frac{100-50}{20-10}[/tex]=[tex]\frac{50}{10}[/tex]

50÷10=5

Answer: y = 20*4^x

Step-by-step explanation:to find the value of the constants a and b, we just need to use the points given in the equation and solve the system of equations:

point (0,20): x = 0 and y = 20:

20 = a*b^0 = a*1 = a

a = 20

point (2,320): x = 2 and y = 320

320 = 20 * b^2

b^2 = 16

|b| = 4

b = 4 or b = -4

So we have two exponencial equations that pass through these points:

y = 20*4^x and y = 20*(-4)^x

As the questions asks for just one equation, we can answer y = 20*4^xIf you have two points, (x1, y1) and (x2, y2), you can define the exponential ... these points by substituting them in the equation y = abx and solving for a and b. ... In this form, the math looks a little complicated, but it looks less so after you ... Taking 1910 as the starting point, this gives the pair of points (0, 1.75) and (100, 6.87). which well turn out to be y=6(4)^x

Step-by-step explanation:

Step-by-step explanation:

y = mx + c

When x = 0, y = 2.

=> (2) = m(0) + c, c = 2.

When x = 3, y = 8.

=> (8) = m(3) + 2, 3m = 6, m = 2.

Hence the answer is y = 2x + 2.

Answer:

∠RTS = 57°

x=9

Explanation:

By just factoring out integers starting from 10 and going down. You can factor each one out. Add all together. And see whether all angles equal 180. And if they do. Then that's what x equals. Not the smartest of explanations but it works lol.

Answer:

y = 40

Step-by-step explanation:

Given

[tex]\frac{y}{8}[/tex] = 5 ( multiply both sides by 8 to clear the fraction )

y = 8 × 5 = 40
