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

height

h = 9 cm

diagonal

d = 16.3095064 cm

total surface area

Stot = 518 cm2

Stop = 88 cm2

bottom surface area

Sbot = 88 cm2

volume

V = 792 cm3

8 x 9 x 11 is 792, 792 x 1/2 is 396, which should be the correct answer.

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.

Step-by-step explanation:

The answer is where the two lines cross

x=2

y=4

Answer:

The orthocenter of a triangle is the point at which the three altitudes of a triangle intersect.  This involves creating 3 lines, one from each vertex (K, L, and M) perpendicular to the line segment opposite it, so K⊥LM, L⊥KM, and M⊥KL.

Because these three lines intersect at one point, you only need to do this procedure for two of the three altitudes.  Because K and M are on the same Y coordinate (-4), lets do this for LM and KL

First, we need to find the slope of the perpendicular to each line segment, so we need the slope of LM and KL.

The slope is the change in Y over the change in X

Slope LM = 6 -(-4) / 2-7 = 10/-5 = -2

Slope KL =  -4-(6) / 4-2 = -10/2 = -5

The slope of a perpendicular line is the negative reciprocal of the slope of the given line, so for

the slope of K⊥LM has to be 1/2 and

the slope of M⊥KL has to be 1/5

Second, the vertex has to be on a line with that slope.  So using the point-slope formula

(y-y1) = m(x-x1) , where x1,y1 is a point on the line for each line gives us

K⊥LM:  y-(-4) = 1/2(x-4)

M⊥KL:  y-(-4) = 1/5(x-7)

Third, find the point on both lines, are where the two equations are equal

So, 1/2(x)-2 = 1/5(x) - 7/5;

5x - 20 = 2x - 14

3x = 6 --> x=2

y+4=-1 --> y=-5

Hi there,

Recall how each bracelet sells for 6 dollars.

Hence, the expression for selling b bracelets is 6b, where b is the number of bracelets sold for the price of 6 dollars.

Profit is the actual amount of money that is earned after you subtract expenses from the total sales.

For instance, if you make $100 from selling items, and you spent $25 on your supplies, then your profit is [tex]100-25=75[/tex].

In this case, you need to subtract the $28 spent on supplies from the amount of money that you have made, which is the expression 6b.

Hence, the expression for the profit is: [tex]6b-28[/tex]

Hope that helps.

Answer:

c = 13.75

Step-by-step explanation:

Converting the words in the problem into a math equarion, we get:

80% * c = 11

0.8c = 11.

Simplifying, we get:

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.

Step-by-step explanation:

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
