Answer: 30%

Step-by-step explanation:

She spent $24 dollars out of the total money she had which was $80. The 24 represents the portion of the money that was spent on fruits. So therefore to find the percentage for put the portion used ($24) divided by the the total ($80) multiplied by a hundred to get the 30%.

Hope this helps :)

Step-by-step explanation:

Put the first number on top and the second on the bottom, then simplify them.

Answer:

perimeter = 2(8x+3) + 2(5) area= (8x+3) • 5

Step-by-step explanation:

perimeter = 2(length) + 2(width)

if length equals (8x+3) and width equals 5 then you would just plug those numbers into the equation which gives you...

perimeter = 2(8x+3) + 2(5)

area = length • width

like i previously said above if length equals (8x+3) and width equals 5 than you would just plug those numbers into the equation which gives you...

area = (8x+3) • 5

Answer:126

Step-by-step explanation:

Answer:

e. 79/30     f.   18.2

Step-by-step explanation:

Answer:

All of the degrees add up to 90. Therefore, right angle.

Answer:

Add 3 to both sides.

2x=9+3

simplify 9+3 to 12

2x=12

Divide both sides by 12

x= 12

     2

simplify

x=12

Answer:

10 tickets for $31.50

Step-by-step explanation:

So If we divide 22.75 by 7 it gives you 3 dollars and 25 cents per ticket

If you divide 31.50 by 10 it gives you 3 dollars and 15 cents.

So In conclusion 10 tickets for $31.50 dollars is the better buy

Answer:

10 Tickets Is The Better Deal

Step-by-step explanation:

So What You Do Is You Will Divide 22.75 By 7

You Will Get 3.25! That Means Its 3.25 Each For 7 Tickets

For The Next One You Do The Same Thing

You Want To Divide 31.50 By 10

You Will Get 3.15! That Means Its 3.15 Each For 10 Tickets

So 3.15 Is 10 Cheaper Than 3.25 So Getting 10 Tickets Is A Better Deal

Answer: i dont understand the question can you please elaborate

Step-by-step explanation:

Answer:

true

Step-by-step explanation:

Answer:

No

Edit:

Yes, based on original equation. (Credit to greenpumpkin for correction)

Step-by-step explanation:

For this problem, we simply need to find the values of x that can make the equation true.  So, let's begin by isolating the "x" variable.

sqrt(2x + 13) = x + 5

[sqrt(2x + 13)]^2 = (x + 5)^2

2x + 13 = x^2 + 10x + 25

0 = x^2 + 8x + 12

Note, we can remove the sqrt method by squaring both sides of the equation.  Doing this, we see we have a quadratic equation meaning we can apply the quadratic formula to find solutions for x.

[-b +/- sqrt( b^2 - 4(a)(c) ) ] / 2a

Let a = 1, b = 8, and c = 12

[-8 +/- sqrt( (8)^2 - 4(1)(12) ) ] / 2(1)

= [-8 +/- sqrt( 64 - 48 ) ] / 2

= [-8 +/- sqrt(16) ] / 2

= [ -8 +/- 4 ] / 2

So, x = [ -8 + 4 ] / 2  and x = [-8 - 4 ] / 2

x = [-4] / 2 = -2  and x = [-12] / 2 = -6

Hence, the two values of x that can solve this quadratic equation are x = -2 and x = -6.

Therefore, we know that x = -6 is not extraneous, meaning it is a solution to our equation.

Cheers.

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

Edit:

Plugging the value of -6 back into the original equation, we get the following:

sqrt(2x + 13) = x + 5

sqrt(2(-6) + 13) = (-6) + 5

sqrt (1) = -1

1 != -1

Given that 1 cannot equal negative 1, we can say that x = -6 is an extraneous solution. (Credit to greenpumpkin for correction)

Answer:

The answer is C

Solution :

Let y = amount of caffeine at a given time in body.

n = number of hours

So [tex]$\frac{dy}{dn}= - \ Y$[/tex]

[tex]$\Rightarrow \frac{dY}{Y}=- 0.01 \ dn[/tex]

ln Y = -0.01 n + C

At n = 0, Y = 130 mg

ln 130 = -0.01 x 0 + C

C = ln 130

[tex]$ \ln \frac{Y}{130} =- 0.01 \ n$[/tex]

[tex]$Y = 130 \ e^{-0.01n}$[/tex]

When Y = 65

[tex]$65 = 130 \ e^{-0.01 n }$[/tex]

[tex]$\frac{65}{130}=e^{-0.01n}$[/tex]

[tex]$\ln \frac{1}{2} = -0.01 \ n$[/tex]

n = 69.315 hours

At n = 24 hours

[tex]$Y = 130 \ e^{-0.01 \times 24}$[/tex]

Y = 102.26 mg

Answer:

  ∆KAF, by rule LA

Step-by-step explanation:

The angle bisector divides angle FAP into two equal angles KAF and KAP. The two right triangles share side KA, so we have a leg KA and an angle KAF, KAP that are the same in the two triangles. That is enough to invoke rule LA (leg, angle) to claim congruence.

  ∆KAP ≅ ∆KAF by rule LA

Answer:

21 questions

Step-by-step explanation:

Given

[tex]Wrong : Right = 2:7[/tex]

Required

Determine the number of correct answers if he answered 6 wrongly

The required ratio can be represented as:

[tex]Wrong : Right = 6 : X[/tex]

Where X represents number of right answers for 6 wrong answers.

Next, we equate both ratios:

[tex]6:X = 2:7[/tex]

Convert to fraction

[tex]\frac{6}{X} = \frac{2}{7}[/tex]

Cross Multiply

[tex]X * 2 = 6 * 7[/tex]

[tex]2X = 42[/tex]

Divide through by 2

[tex]X = 21[/tex]

Hence, he answered 21 correctly
