Answer:
v = 1 or -3
Step-by-step explanation:
2v^2 + 4v = 6
take 2 as common
2(v^2 + 2v = 3)
v^2 + 2v = 3
Now,
v^2 + 2v - 3 = 0
v^2 - v + 3v - 3 = 0
v(v - 1) + 3(v - 1) = 0
(v - 1) (v + 3) = 0
v = 1 or -3
Answer:
<=>v²+2v-3=0
<=>v²-v+3v-3=0
<=>v(v-1)+3(v-1)=0
<=>(v-1)(v+3)=0
<=>*v-1=0
v=1
*v+3=0
v=-3

Stephon went to the Griffin Fair with $25.50. He bought a hot dog and a drink for $4.25, and he wanted to spend the rest of his money on ride tickets which cost $1.25 each. What is the maximum number of ride tickets that he can buy?
17
Step-by-step explanation:
$25.50-$4.25=$21.5 [ 21.5 is the mony he has left after he bought the food]
$21.25÷$1.25=17 [we will divide the rest of his mony with the cost of 1 ticket so we can get how many tickets he can buy]

The Coyotes pay their aging kicker $725,000 a year. He agrees to a 15% pay cut. What is his new salary?
Given:
Coyotes pay their aging kicker $725,000 a year.
He agrees to a 15% pay cut.
To find:
His new salary.
Solution:
Annual salary before pay cut = $725,000
Annual salary after pay cut = [tex]725,000-\dfrac{15}{100}\times 725,000[/tex]
[tex]=725,000-15\times 7250[/tex]
[tex]=725,000-108,750[/tex]
[tex]=616,250[/tex]
So, monthly new income is
[tex]\dfrac{616,250}{12}\approx 51354.167[/tex]
Therefore, his new salary is $51,354.167 per month.
Answer:
616,250
Step-by-step explanation:
15 percent of 752,000 is 108,750.
752,000 minus 108,750 is 616,250.

What is an equation of the line with slope 6 and y-intercept -4 in slope-intercept form?
Answer: y = 6x-4
Step-by-step explanation:
The formula for slope-intercept is y=mx+b so all you have to do is plug in the slope which is m and plug in the y intercept which would be b
A firecracker is fired straight up into the air out of a window of a building. Its height, in meters, is given by h = − 5 t 2 + 30 t + 20 , where t is the time, in seconds, the fircracker has been in the air.
Answer:
See explanation
Step-by-step explanation:
Given that the equation for the firecracker is h = − 5 t^2 + 30 t + 20
It is impossible to solve this question unless the height (h) in meters is supplied. If the height was supplied, we could set up the quadratic equation and solve it yielding two values for the time. The values of t obtained is the time in seconds required for the firecracker to reach the given height h.
You can apply these tips and solve the question seamlessly.

Answer:
Ok, ok, I see what's happening here
You're face to face with greatness, and it's strange
You don't even know how you feel
It's adorable
Well, it's nice to see that humans never change
Open your eyes, let's begin
Yes, it's really me, it's Maui
Breathe it in
I know it's a lot
The hair, the bod
When you're staring at a demi-god
What can I say except, "You're welcome"
For the tides, the sun, the sky
Hey, it's okay, it's okay
You're welcome
I'm just an ordinary demi-guy
Hey
What has two thumbs and pulled up the sky
When you were waddling yea high?
This guy
When the nights got cold
Who stole you fire from down below?
You're lookin' at him, yo
Oh, also I lassoed the sun
You're welcome
To stretch your days and bring you fun
Also I harnessed the breeze
You're welcome
To fill your sails and shake your trees
So what can I say except you're welcome
For the islands I pulled from the sea
There's no need to pray, it's okay
You're welcome
Ha, I guess it's just my way of being me
You're welcome
You're welcome
Well, come to think of it
Kid, honestly I could go on and on
I could explain every natural phenomenon
The tide, the grass, the ground
Oh, that was Maui just messing around
I killed an eel
I buried its guts
Sprouted a tree, now you got coconuts
What's the lesson?
What is the take-away?
Don't mess with Maui when he's on a break-away
And the tapestry here on my skin
Is a map of the victories I win
Look where I've been
I make everything happen
Look at that mean mini-Maui just tickety-tappin'
(Ha ha ha ha ha ha, hey)
Well, anyway let me say, "You're welcome" (you're welcome)
For the wonderful world you know
Hey, it's okay, it's okay, you're welcome (you're welcome)
Well, come to think of it, I gotta go (hey)
Hey, it's your day to say, "You're welcome" (you're welcome)
'Cause I'm gonna need that boat
I'm sailing away, away, you're welcome (you're welcome)
'Cause Maui can do anything but float
You're welcome
(You're welcome)
You're welcome
And thank you

Mr. Win owns a toy store. He wants to display 12 new motion toys in the store window. Each toy uses 3 batteries. If N represents the total number of batteries he needs, which sentence is correct?
Answer: See explanation
Step-by-step explanation:
You didn't state the sentences but let me help out based on the information given.
Number of new motion toys = 12
Number of batteries used by each toy = 3
Since N represents the total number of batteries he need, the value of N will be:
= Number of toys × Number of batteries used by each toy
= 12 × 3
= 36
That means N equals 36.

Which equation represents the graph shown?y =
y = x - 35
y = x + 35
y = 35 x
y = x/35 (fraction)
Answer:
y = 35xStep-by-step explanation:
If you notice, point 4 on the x-axis (horizontal) coincides with 140 on the y-axis.
If you multiply x * 35 = 140
x is four.

Answer:
x = 36.27
Step-by-step explanation:
By using the steps to find sin θ backwards, we can find x, the hypotenuse.
sin θ = [tex]\frac{opposite}{hypotenuse}[/tex] or side [tex]\frac{a}{c}[/tex] (as seen in my example picture).
We already know the value for sin (α), which is 32° because its given. The opposite side (a) is 20 and the hypotenuse side (c) is x which are both also given.
So the equation now looks like:
sin 32° = [tex]\frac{20}{x}[/tex]
Don't solve for the sin 32 yet! First, we have to isolate the variable.
To get rid of the x in the denominator you have to multiply both sides by x:
( sin 32 ) · x = ( [tex]\frac{20}{x}[/tex] ) · x
( sin 32 ) x = 20
Then, you have to divide both sides by sin 32 to get x by itself:
(( sin 32 ) x ) ÷ ( sin 32 ) = 20 ÷ ( sin 32 )
x = 20 ÷ ( sin 32 )
Lastly, you have to use a calculator to find 20 ÷ ( sin 32 ), and it should give you 36.2695543766.
The question asks you to round to 2 decimal places so:
x = 36.27

Which equation can be used to represent the statement? Half of a number minus seven is one and five-tenths. One-half + x = 1.5 One-half x minus 1.5 = 7 StartFraction x over 2 EndFraction minus 7 = 1.5 7 minus StartFraction x over 2 EndFraction = 1.5
Given:
Statement is "Half of a number minus seven is one and five-tenths."
To find:
The equation for the given statement.
Solution:
Let the unknown number be x.
Half of a number : [tex]\dfrac{x}{2}[/tex]
Half of a number minus seven : [tex]\dfrac{x}{2}-7[/tex]
One and five-tenths : [tex]1\dfrac{5}{10}=1.5[/tex]
Half of a number minus seven is one and five-tenths:
[tex]\dfrac{x}{2}-7=1.5[/tex]
The required equation for the given statement is [tex]\dfrac{x}{2}-7=1.5[/tex].
Therefore, the correct option is C.

A jacket was on sale for 20% off its original price of $60. Now, it is on sale for an additional 10% off its previous sale price. Determine whether each statement is true or false. True False The jacket is now 40% off its original price. The jacket now costs $48.00. The jacket is now 72% of its original price. The jacket now costs $43.20.
Answer:
Step-by-step explanation:
Step one:
given
original price= $60
discount =20% of 60
discount = 20/100*60
discount = 0.2*60
discount = $12
selling price= 60-12= $48
Added price= 10% off $48
Added price= 10/100 *48
Added price= 0.1 *48
Added price= $4.8
new price= 4.8-48=$43.2
the new price of the jacket is $43.2
1. The jacket is now 40% off its original price
40/100*60=$24-----False
2. The jacket now costs $48.00-----False
3. The jacket is now 72% of its original price= 72/100*60=$43.2----True
4. The jacket now costs $43.20------True

Step-by-step explanation:
Angad is 9 years older than Peter. Krutika is 12 years younger than Peter. If the total of their ages is 75, how old is the eldest of them?
Answer:
Angad the eldest=32+9=41year
Step-by-step explanation:
Let peter is x years old. Then Angad is x + 9 years old and Krutika is
x - 12 years old. Then
x+(x+9)+(x−12)=75⟹3x−21=75⟹x−7=25
⟹x=32years
Angad the eldest=32+9=41year
