Answer 1

Answer: D

Explanation:

Area of triangle = [tex]\frac{1}{2} bh[/tex]

b = base lengthh = height

Area of ΔABC =

[tex]\frac{1}{2} CE * AB[/tex][tex]\frac{1}{2} BD * AC[/tex]

Since it's the same triangle, those two areas should equal each other:

[tex]\frac{1}{2} CE*AB=\frac{1}{2} BD*AC\\\frac{1}{2} *9*8=\frac{1}{2} *7*AC\\\frac{1}{2} *72=\frac{7}{2} AC\\36*2=7AC\\AC=\frac{72}{7} =10\frac{2}{7}[/tex]

I hope this is correct

Explanation:

MY COUNTRY

(english)

Such a small country, spread on an isthmus

where the sky is clearer, the sun brighter;

all your music echoes within me, like the sea

in the small cell of the conch.

Yet again, there are times I feel dread

when I don’t see the way back to you…

Perhaps I’d never have known such love,

if destiny hadn’t carried me over the sea.

______________________________________

(Español)

Un país tan pequeño, extendido en un istmo

donde el cielo es más claro, el sol más brillante;

toda tu musica resuena dentro de mi, como el mar

en la pequeña celda del caracol.

Una vez más, hay momentos en los que siento pavor

cuando no veo el camino de regreso a ti ...

Quizás nunca hubiera conocido tal amor

si el destino no me hubiera llevado sobre el mar.

if (x,y) is a solution to the equation 3(x+y)=y what is the value of x over y

Answers

Answer:

-2/3

Explanation:

3(x+y) = y

3x + 3y = y

3x = -2y

x = (-2/3)y

(-2/3)y/y = -2/3

Double check:

x = -2

y = 3

3(-2+3) = 3

3(1) = 3

3=3

[tex]\displaystyle\ 3(x+y)=y \\\\3x+3y=y\\\\ 3x=-2y\\\\\boxed{x=-\frac{2}{3} y \ \ or \ \ y=-1.5x}[/tex]

What color is a carrot?
If you dig a 6ft hole, how deep is that hole?



Answers

R-O-J-O

Purple, OG orange and pale boi

That’s a deep hole, but not deep enough for 2

The spelling of "red" is R-E-D.

The color of a carrot is typically orange

If you dig a 6ft hole, the depth of the hole would be 6 feet.

Spelling of "red":

"Red" is spelled as R-E-D, with the letters R, E, and D. It is a primary color often associated with objects or surfaces that reflect this specific wavelength of light.

Color of a carrot:

Carrots are commonly known for their orange color, which is the most common variety.

However, carrots can also come in other colors, such as purple, yellow, white, and red.

These variations are due to different pigments present in the carrots, such as beta-carotene (which gives the orange color) and anthocyanins (which provide purple and red hues).

Depth of a 6ft hole:

When you dig a hole that is 6 feet deep, it means the hole extends vertically downward from the surface to a depth of 6 feet.

It is a measurement of distance from the top of the hole to the bottom. This depth is significant when considering construction, landscaping, or other activities that involve digging or excavation.

(root 8)^a = 4^b/3
If a and b are positive numbers in the equation
above, then what is the value of a/b ?

A. 4/9
B. 2/3
C. 3/2
D. 9/4

Answers

Answer:

4/9

Explanation:

√8^a=4^b/3.

You can rewrite √8^a as 8^a/2.

So then that would be, 8^a/2=4^b/3.

If both sides have the same base, we could then make the fractional exponents equal to each other. Since 2^3=8 and 2^2=4, we can make that possible.

2^3(a/2)=2^2(b/3).

2^3a/2=2^2b/3.

 So now 3a/2=2b/3.

Then we isolate the a, by multiplying 2/3 on both sides and are left with:

a=2/3*2/3*b

a=4/9*b

Then you divide both sides by b to get:

a/b=4/9.

Which line or lines in this editorial show faulty reasoning?
Save Teenage Driving: A Call to Arms
an editorial by Sophie Behrend
Recently, House Representative Ken Weaver of Washington State proposed bill (House Bill R-9687b) that would raise the legal driving age to 21.
You heard me right-Congress is considering raising the driving age to 21. If you are like me, such a law would be a catastrophe and would only
mean one thing: the end of life as we know it.
Representative Weaver claims that his bill is motivated by "safety." He argues, "Nearly half of all accidents involve people under the age of 21."
Representative Weaver also claims, "Raising the driving age would mean raising the level of safety on America's roads."
But would ask Representative Weaver: Do not "nearly half" of all accidents involve men, and would not the streets be safer, then, if male
drivers were outlawed? And what about the percentage of accidents that occur on paved roads-should we do away with paved roads too?
Weaver also claims that "a majority of seat belt violations" are the fault of the under-21 crowd. But let me ask you this: DO people under the age
of 21 reallywear their seat belts less often than older people, or are they just caught more often? That is, we know the police have their eye on
the teenagers, but are they looking at the adults as well?
t But I can hear it now: "If teenagers are all so safe, why do they have such high accident rates?" Here's a possible answer: inexperience. Like
anybody who is inexperienced, the teenage driver must
suffer through a legitimate period of self-doubt and skills acquisition. Chances are, if the
driving age were moved to 21, we would see 21 - to 24-year-olds causing the largest percentage of safety problems-not because of a maturity
problem, mind you,
but just because they would be inexperlenced at driving.

[tex] n - \sqrt{c + 5 = 1} [/tex]
in the equation above, C is a constant. If n= 5, what is the value of c?

Could you say how you got rid of the negative sign in front of the square root in the process plz

Answers

Answer:

c=11

Explanation:

[tex]n - \sqrt{c + 5} = 1[/tex]

[tex]5 - \sqrt{c + 5} = 1[/tex]

Add sqr root of c+5 to both sides

[tex]5 = 1 + \sqrt{c + 5} [/tex]

[tex]4 = \sqrt{c + 5} [/tex]

[tex]16 = c + 5[/tex]

[tex]c = 11[/tex]

Answer:

c is 11

Explanation:

[tex]n - \sqrt{c + 5 } = 1 \\ 5 - \sqrt{c + 5} = 1 \\ [/tex]

make -√c+5 the subject:

[tex] - \sqrt{c + 5} = 1 - 5 \\ - \sqrt{c + 5} = - 4[/tex]

divide through out by -1 :

[tex] \frac{ - \sqrt{c + 5} }{ - 1} = \frac{ - 4}{ - 1} \\ \\ \sqrt{c + 5} = 4[/tex]

square both sides;

[tex] {( \sqrt{c + 5} )}^{2} = {4}^{2} \\ c + 5 = 16 \\ c = 11[/tex]

the system of equations above?
A) 6
B) 12
C) 18

Answers

Answer:

5x + x^2 - 5x + 3 = 39

-> x^2 = 36

-> x = 6
