Answer:

Step-by-step explanation:

The most basic area formula is the formula for the area of a rectangle. Given a rectangle with length l and width w, the formula for the area is: A = lw (rectangle). That is, the area of the rectangle is the length multiplied by the width.

Answer:

110 grams

Step-by-step explanation:

CO2 molecule is made up of Carbon (atomic mass =12) and oxygen (atomic mass=16).

So first finding the mass of 1 molecule of CO2 which is equals to

= mass of 1 carbon atom + masses of 2 oxygen atom, we get

= 12+(16*2)= 12+32= 44 a.m.u.

Now 1 molecule of CO2 has mass 44 amu so mass of 1 mole CO2 will be 44 grams.( 1 a.m.u.=1.6729*10^-33 grams. 1 mole = 6.022*10^23, so 44 a.m.u.=73.6076*10^-33 grams approx. For one mole CO2, 73.6076*10^-33*6.022*10^23 which is approximately equals to 44 grams. )

1 mole CO2= 44grams, so 2.5 moles = 44*2.5= 110 grams

So our answer is 110 grams.

lowkey hope this helped you, good luck whatever you need it for Imaooo

Answer:

All solutions or infinite.

Step-by-step explanation:

Turn 2y = -4x + 6 into standard form - divide by 2

Y = -2x + 3

2x + y = 3

Substitute the y equation in for y.

2x - 2x + 3 = 3

The x variables cancel out.

3 = 3

Which is true so it means all solutions.

Hope this helps.

Answer:

[tex]x=4[/tex], [tex]y=61[/tex]

Step-by-step explanation:

Since the triangles are congruent, we already know that they have the same angles and sides.

We can solve for the missing side with this equation:

[tex]51=12x+3[/tex]

subtract [tex]3[/tex] from both sides

[tex]48=12x[/tex]

divide both sides by [tex]12[/tex]

[tex]x = 4[/tex]

Due to the Angle Theorems we already know [tex]2[/tex] of the angles on the triangle:

[tex]63[/tex] and [tex]56[/tex]

We can solve for the missing angle with this equation:

[tex]A+B+C=180[/tex]

[tex]63+56+y=180[/tex]

[tex]119+y=180[/tex]

subtract [tex]119[/tex] from both sides

[tex]y=61[/tex]

Answer:

n =[tex]\frac{5}{10}[/tex]

Step-by-step explanation:

Answer:

n= 2 and two thirds

Step-by-step:

this is the equation

3/10n=4/5

so to get n by itself, you multiply both sides by 10/3. I did 4/5 times 10/3 and I got 2/2/3, or two and two thirds

Answer:

for #1 it's 1, 4, 5, 6

for #2 it's both lines have the same slope

for #3 it's both lines have a different y-intercept

Step-by-step explanation:

#1 explanation: all of them have the y-intercept of -8

ex. y = 3x (- 8) y = 5x (-8) y = 2x (-8) y = (1/3)x (-8)

#2 explanation: both have a slope of (1/4)

#3 explanation: y = (1/4)x there is not y-intercept that we know of and y = (1/4)x - 5 the y-intercept is at -5 therefore the y-intercepts are different

Answer:

∠ b = 42°

Step-by-step explanation:

b and 48° form a right angle, then

b = 90° - 48° = 42°

Answer:

42 degrees

Step-by-step explanation:

The angle shared by 48 and b is 90 total degrees.

Subtract 48 from 90 to find the measure of b

Answer:

y intercept=5

Step-by-step explanation:

to find Y intercept substitute the value of x as 0

Answer:

the y intercept is 5

Step-by-step explanation:

slope = mx + b

in your case:

y = slope

2x = mx

5 = y intercept

Answer:

1. the force that attracts a body toward the center of the earth, or toward any other physical body having mass.

2. extreme or alarming importance; seriousness.

"crimes of the utmost gravity"

Step-by-step explanation:

Gravity, also called gravitation, in mechanics, the universal force of attraction acting between all matter. ... On Earth all bodies have a weight, or downward force of gravity, proportional to their mass, which Earth's mass exerts on them. Gravity is measured by the acceleration that it gives to freely falling objects.

Explanation:

s = Sam's age right now

2s = the mother's age right now, since she is twice as old as Sam currently.

In 12 years time, Sam will be s+12 years old.

12 years ago from this current year, the mother was 2s-12 years old.

Since we're told these future and past ages line up, this means s+12 and 2s-12 are the same value

Set the expressions equal to one another and solve for s.

s+12 = 2s-12

s-2s = -12-12

-s = -24

s = 24

Sam is currently 24 years old.

His mother is currently 2s = 2*24 = 48 years old.

12 years ago, his mother was 2s-12 = 48-12 = 36 years old.

12 years from now, Sam will be s+12 = 24+12 = 36 years old.

Since we get 36 each time, this confirms we have the correct answers.

Answer: Bertha nació el 18 de septiembre de 1990.

Step-by-step explanation:

Gonzalo nació el 18 de septiembre de 1945.

Bertha nació cuatro décadas y un lustro después.

Una década son 10 años

Un lustro son 5 años

Entonces 4 décadas y un lustro son:

4*10 años + 5 años = 45 años

Esto significa que Bertha nació 45 años después que Gonzalo.

Entonces si Gonzalo nació en 1945, Bertha nació en el año:

1945 + 45 = 1990

Bertha nació el 18 de septiembre de 1990.

La fecha de nacimiento de Bertha es el 18 de septiembre de 1990.

A decade is composed of 10 years. So, if there are 'x' decades, then that means there are going to be [tex]10 \times x[/tex] years in it.

For this case, we are given that:
Date of birth of Gonzelo is 18th of Sept. 1945

Bertha born after 4 decades and 5 years of Gonzelo's birth.

4 decades = 4 times 10 = 40 years

Thus, 4 decades + 5 years = 40 + 5 = 45 years.

45 years after 1945 uis 1945 + 45 = 1990

Thus, date of birth of Bertha is 18th Sept. 1990
