PLEASE ANSWER QUICK!!! The volume of ammonia in a balloon is now 6.1 L after changing the temperature from 52 °C to 79 °C. What was the original volume?

Answer: 60%

Step-by-step explanation:

1440/2400

Divide both numbers by 480

The quotient is now:

3/5

To find the percentage of a fraction of people, you have to multiply the fraction by 100%

3/5 x 100% = 300/5

300/5 = 60%

Step-by-step explanation:

Y=Mx + b is linear and in this case we have Y= 0x - 6 or Y=0x + (-6).

Answer:

8. the line the vertical

9. y=3/4x-10

Step-by-step explanation:

For number nine, you must find b with the information given if you were to use slope intercept form.

4= 3/4(-8)+b

4= -6+b

-10=6

Now, just plug this number back into the equation.

y= 3/4x-10

Answer:

20.25

Step-by-step explanation:

i think its asking for the long side

the pythagorean theorem states that in a right triangle a^2+b^2=c^2

a is 19

b is 7

c is the long side

19^2= 361

6^2= 49

361+49=410

410 =c^2

square root of 410 = ~20.25

Answer:

[tex]hypotenuse = \sqrt{ {19}^{2} + {7}^{2}} \\ = \sqrt{361 + 49} = \sqrt{410} \\ = 20.25[/tex]

20.25 is the right answer.

Answer:

Since the Airbus A300 model airplane was made to scale, measuring 36 centimeters, while the real airplane measures 54 meters, to determine the scale ratio between both planes, the following calculation must be performed:

36cm = 0.36m

0.36 = 1

54 = X

54 x 1 / 0.36 = X

150 = X

Therefore, the scale ratio between the model and the real plane is 150:1.

Answer:

13:20

Step-by-step explanation:

no. of girls=26

total no. of students =40

ratio of girls to total no. of students=26:40

which means, the ratio is 13:20

Answer:

1) just make an equation (answer below)

SO the new bottle is 30 ounces

The old bottle was 25 percent more then the new one

So we can just find 25 percent of 30

And add it

That is the most simple way but I would just do

30*1.25 Its the same thing but if you think a bout ti, the new bottle can Only hold 30 ounces, 30 ounces is 100 percent of the new bottle, if you multiply 1.25 its adding 25 percent so it Turns a 2 step into a 1 step.

1.25*30=37.5

The larger bottle was 37.5 ounces

Answer:

[tex]x = 0\; ,-\frac{3}{4}[/tex]

Step-by-step explanation:

[tex]36x^3 + 27x^2 = 0[/tex]

[tex]=> 9x^2(4x + 3) = 0[/tex]

Here, x will have 2 values :-

1) [tex]9x^2(4x + 3) = 0[/tex]

[tex]=> \frac{9x^2(4x + 3)}{(4x+3)} = \frac{0}{4x+3}[/tex]

[tex]=> 9x^2 = 0[/tex]

[tex]=> \frac{9x^2}{9x} = \frac{0}{9x}[/tex]

[tex]=> x = 0[/tex]

2) [tex]9x^2(4x + 3) = 0[/tex]

[tex]=> \frac{9x^2(4x + 3)}{9x^2} = \frac{0}{9x^2}[/tex]

[tex]=> 4x+3 = 0[/tex]

[tex]=> 4x+3 -3 = 0 - 3[/tex]

[tex]=> 4x=-3[/tex]

[tex]=> \frac{4x}{4} = \frac{-3}{4}[/tex]

[tex]=> x = -\frac{3}{4}[/tex]

Answer:

f(-10)=105

Step-by-step explanation:

When something says f(x), the (x) is your plugin value. So basically in this scenario, x= -10

    1) f(-10)= (-10)^2+5

    2)f(-10)= 100+5

    3) f(-10)= 100+5

Ok hopefully I remembered my properties of exponents correctly, but I'm pretty sure that's the answer. If it isn't, you should try making the 100 negative instead of positive from step 2 and work from there.

Answer:

$0.56

Step-by-step explanation:

Cost of 3 1/3 pounds of beef at $1.35 per pound

= 3 1/3 × 1.35

= 10/3 × 1.35

= $4.5

He divides the meat into 8 equal packages. To the nearest cent, the price of each package is $

= $4.5 / 8

= $0.5625

Approximately $0.56 to the nearest cent

Question:

Brianna solved a two-step equation, but she made a mistake along the way.

[tex]0.1x + 3 = 1.7[/tex]

Line 1 : [tex](-3) + 0.1x + 3 = 1.7 + (-3)[/tex]

Line 2 : [tex]0.1x = -1.3[/tex]

Line 3 : [tex](-0.1) + 0.1x = -1.3 + (-0.1)[/tex]

Line 4: [tex]x = -1.4[/tex]

Answer:

On Line 3, Brianna should have divided by 0.1 instead of subtracting 0.1.

Step-by-step explanation:

Required

Where did she make a mistake?

To do this, we simply analyse her workings one step at a time

Equation: [tex]0.1x + 3 = 1.7[/tex]

Line 1 : [tex](-3) + 0.1x + 3 = 1.7 + (-3)[/tex]

This is correct because she subtracted 0.3 from both sides

Line 2 : [tex]0.1x = -1.3[/tex]

This is also correct because she performed the arithmetic correctly

Line 3 : [tex](-0.1) + 0.1x = -1.3 + (-0.1)[/tex]

This is incorrect.

Division by 0.1 is expected not subtraction

Answer:

It's C

Step-by-step explanation:

Answer:

13°C

Step-by-step explanation:

The number of hours that the temperature fluctuates is irrelevant to the problem.

This problem is asking how many degrees did the temperature increase in order to go back to 30°C after being decreased by 13°C.

Find the new temperature after it decreased:

If the temperature after decreasing is 17°C, it needs the same amount it was decreased by to go back to 30°C.

Therefore, the temperature subsequently increased by 13°C to go back to 30°C after being decreased by 13°C.

Answer:

Step-by-step explanation:

you square 72 and 65 and add them together then take the square root of your answer aka 97 and thats the hypotenuse

Answer:

JK=8

Step-by-step explanation:

the sides are equal so set KL equal to LM

b+5=3b-1

b=6=3b

6=2b

b=3

b+5

3+5

8

Using the property of the sides of a rhombus, the missing length is determined as: B. JK = 8.

Thus:

KL = ML

Substitute

b + 5 = 3b - 1

b - 3b = -5 - 1

-2b = -6

b = 3

Find JK

JK = KL = b + 5

JK = b + 5

JK = 3 + 5

JK = 8

Therefore, using the property of the sides of a rhombus, the missing length is determined as: B. JK = 8.

Answer: 100 x 2^ t/9

Step-by-step explanation:

The initial population of 100 that doubles in 9 years, gives the

expression for population as; [tex]\underline{ P = 100 \cdot e^{0.077 \cdot t}}[/tex].

Given parameters are;

The time it takes the population to double = 9 years

The initial population count = 100

Required:

The expression that gives the population after t years.

Solution:

The population as a function of time can be expressed as an

exponential function as follows;

[tex]P = \mathbf{P_0 \cdot e^{c \cdot t}}[/tex]

At the start, t = 0, P = 100, we have;

[tex]100 = \mathbf{ P_0 \times e^{c \times 0} }= P_0[/tex]

Therefore;

P₀ = 100

After 9 years, we have;

P = 2·P₀

Therefore;

[tex]2 = \mathbf{ e^{c \times 9}}[/tex]

ln(2) = 9·c

[tex]c = \dfrac{ln(2)}{9} \approx 0.077[/tex]

The function that gives the population is therefore;

Answer:

The difference of weight is [tex]2[/tex] pounds.

Step-by-step explanation:

Given:  The line plots shows the weights of [tex]9[/tex] grapefruits

To find: The difference in the total weight of all the [tex]1\frac{1}{2} lb[/tex]  grapefruits and the total weight of all the [tex]1 \frac{1}{4}lb[/tex] grapefruits.  

Firstly, we need to convert the given mixed fractions as following:

[tex]1\frac{1}{2} lb=\frac{2+1}{2}=\frac{3}{2}lb[/tex]

[tex]1\frac{1}{4} lb=\frac{4+1}{4}=\frac{5}{4}lb[/tex]

Now, we know that,

Point diagrams divide a sample into different classes, and allow to observe the frequencies of each class.

In this case, the different weights of the grapefruit constitute the classes. From a sample of 10 grapefruit, some will weigh  others weigh.

We need to observe the dot diagram to know how many  grapefruit we have of weight [tex]\frac{3}{2} lb[/tex] and how many  grapefruit we have of weight [tex]\frac{5}{4} lb[/tex]. In other words, we need to know, in the diagram, how many points there are about class of  [tex]\frac{3}{2} lb[/tex] and how many points there are about class of   [tex]\frac{5}{4} lb[/tex].

Then, the total difference between all grapefruit of  pounds and all grapefruit of pounds is calculated as follows:

[tex]x (1\frac{1}{2} ) - y (1\frac{1}{4} ) = Z[/tex]

Where

[tex]Z[/tex]: Weight difference

[tex]x[/tex]: Quantity of [tex]1\frac{1}{2} lb[/tex]  grapefruit

[tex]y[/tex]: Quantity of [tex]1\frac{1}{4}lb[/tex] grapefruit

Suppose that of the [tex]10[/tex] total grapefruits, [tex]3[/tex] of them weigh [tex]1\frac{1}{2} lb[/tex]  and [tex]2[/tex] of them weigh [tex]1 \frac{1}{4}[/tex]  pounds. This is: [tex]x=3[/tex] and [tex]y=2[/tex]

Now,

[tex]3(\frac{3}{2} )-2(\frac{5}{4} )[/tex]              

[tex]=\frac{9}{2} -\frac{5}{2}[/tex]                    

[tex]=\frac{4}{2}[/tex]            

[tex]=2[/tex]

Hence, for this case, the difference of weight is [tex]2[/tex] pounds.
