find the surface area:

Answer:

x = - [tex]\frac{1}{7}[/tex], x = [tex]\frac{3}{2}[/tex]

Step-by-step explanation:

Given

(7x + 1)(2x - 3) = 0 ← in standard zero product form

Equate each factor to zero and solve for x

7x + 1 = 0 ⇒ 7x = - 1 ⇒ x = - [tex]\frac{1}{7}[/tex]

2x - 3 = 0 ⇒ 2x = 3 ⇒ x = [tex]\frac{3}{2}[/tex]

Answer:

x = - 1 / 7   and x = 3 / 2

Step-by-step explanation:

14x2 - 21 x + 2x- 3 = 0

14x2  - 19x -3 = 0

x = 1 9 + 23 / 28 = 3 / 2

x = 19 - 23 / 28 = - 1 / 7

7x + 1 = 0 ⇒ 7x = - 1 = -1 / 7

2x - 3 = 0 ⇒ 2x = 3 = 2/ 3

Hope this answer helps you :)

Answer:

Hello! answer: B.

attention: im using 3.14 for pi so answers may vary. ok so in this picture we are provided with the diameter to find area we can do radius × radius × 3.14

16 ÷ 2 = 8 8 × 8 = 64

64 × 3.14 = 200.96 When you round this up it's 201 so approximately the answer would be B. Hope that helps!

Answer:

Answer:

Option C: (3*x)^2 = 324

Step-by-step explanation:

Janene is solving the equation:

Log₃ₓ(324) = 2

First, some rules we need to remember:

Logₙ(x) = Ln(x)/Ln(n)

and:

Ln(x^b) = b*Ln(x)

So we can rewrite our expression as:

Log₃ₓ(324) = Ln(324)/Ln(3*x) = 2

Ln(324) = 2*Ln(3*x)

Now we can use the second property:

Ln(324) = 2*Ln(3*x) = Ln( (3*x)^2 )

The arguments in both sides must be the same thing, then:

324 = (3*x)^2

This is the exponential equation she needs to solve.

Then the correct option is C.

Original price = 3300

sale = 20% = 3300×20/100 = 660

Selling price= 3300-660= 2640 rs

the sale price of the bicycle is 2640 Rs

I THINK it's B 1/2

Step-by-step explanation:

Sorry if wrong

Answer:

In this case, D

Step-by-step explanation:

Sin(30+60)=0.8939966636 which can be rounded to 0.89.

Now that we got that out of the way, we supposedly can follow the process of elimination.

It's clearly not A since we know the answer isn't equivalent to zero.

1/2 equals 0.5, meaning B's also not it.

We also know the answer isn't D, since 0.89 does not equal 1.

That only leaves C. Yet when check, just in case, √3/2 equals 1.22474487, meaning that's not the answer.

We've eliminated every answer so far, meaning we should go back and check our work. As I stated earlier, 0.8939966636 can be rounded to 0.89, but it can also be rounded to 1. Meaning, the closest answer to what we're looking for is D.

Of course, there could always be an error in the question itself, but unfortunately, there's no way to confirm that without asking your instructor or tutor.

I hope that helps.

Hi there!

Answer:

2

Step-by-step explanation:

you have to dived 3/4 by 3/8= 24/12=2

Answer:

11.since diagonal are equal of rectangle

QS=RT

4x+6=6x-4

6+4=6x-4x

2x=10

x=10/2

x=5

now

diagonal :4x+6=4*5+6=26

12.

again

QS=RT

9x+12=11x-10

12+10=11x-9x

2x=22

x=11

now

diagonal=9*11+12=99+12=111

========================================

Explanation:

distance = rate*time

90 = r*t

where r is the slower speed and t is the time it takes when going that slower speed.

If r is bumped up 24 mph faster, to r+24, then Santos takes t-12 hours to get there. The second equation is

90 = (r+24)(t-12)

-------------------------------------

We can solve the first equation for r to get r = 90/t

Then plug this into the second equation and do a bit of algebra

90 = (r+24)(t-12)

90 = (90/t+24)*(t-12)

90 = 90 - 1080/t + 24t - 288

90t = 90t - 1080 + 24t^2 - 288t

0 = 90t - 1080 + 24t^2 - 288t-90t

0 = 24t^2 - 288t - 1080

24t^2 - 288t - 1080 = 0

If you apply the quadratic formula, then you should get the two solutions t = -3 and t = 15. Due to time constraints, I'll skip these steps.

We'll ignore the negative t value. It makes no sense to have a negative time.

So we focus on t = 15 as the only solution.

-------------------------------------

If t = 15, then,

r = 90/t

r = 90/15

r = 6

Santos rode his bike at 6 mph at first. Going this speed means he takes 15 hours.

If he rode 24 mph faster, at 6+24 = 30 mph, then he would ride for 15-12 = 3 hours instead. Note that 90/30 = 3.

Answer:

20/89

Step-by-step explanation:

The question wants the student from Gryffindor. So we will take the total of the Gryffindor student only is 178

Then they want the student who has owl then is 40.

So you use 40/178

And get the simple fraction 20/89

Answer:

5.2

Step-by-step explanation:

if you take 31.2 and divide it by 6 you will get 5.2

Answer:

5 1/5 pounds which equals 5.2 pounds

Step-by-step explanation:

31 2/10 = 31 1/5

31 1/5 = 156/5

156/5 ÷ 6 means 156/5 x 1/6

multiply numerators to get 156

multiply denominators to get 30

156/30 = 5 6/30 or 5 1/5 simplified

Answer:

x=+[tex]\frac{\sqrt{4y-7}-1 }{2}[/tex]

Step-by-step explanation:

Quadratic function =( -b+[tex]\sqrt{b^2+4ac}[/tex]  )/2a

x^2+x+2-y=0

x=-1+[tex]\sqrt{1^2-4(2-y)}[/tex] /2

x=-1+[tex]\sqrt{4y-7}[/tex] /2

x=+ [tex]\frac{\sqrt{4y-7}-1 }{2}[/tex]

According to the unit circle, the value of sin will be :

[tex] \boxed{\boxed{\longrightarrow \dfrac{ - \sqrt{3} }{2} }}[/tex]

Since, value of sin[tex](\theta)[/tex] is always negative in the fourth quadrant, therefore it can't be [tex]\dfrac{1}{2}[/tex].
