Answer:

CAN U CUMMM?

Step-by-step explanation:

Answer:

Step-by-step explanation:

CA and CB are both opposite equal 90 degree angles so are equal so we can say

8x-12=4x

4x-12=0

4x=12

x=3, since CA=4x

CA=4(3)=12

Answer:

x = 13

Step-by-step explanation:

Since the triangles are congruent by AAS.

6x - 1 = 4x + 25

or 2x = 26

x = 13

Answer:

Step-by-step explanation:

D Add 7 to both sides

This makes it 3x=37

x=37/3

Answer:

[tex]\sqrt{\frac{(8b^2-9a^2)^2}{576a^2}-\frac{2b^2+5ab+2a^2}{12a} } -\frac{8b^2-9a^2}{24a} \\\\or\\-\sqrt{\frac{(8b^2-9a^2)^2}{576a^2}-\frac{2b^2+5ab+2a^2}{12a} } -\frac{8b^2-9a^2}{24a}[/tex]

Step-by-step explanation:

The quadratic formula for

[tex]ax^2+bx+c=0[/tex]

the solution is: (-b±√(b²-4ac))/(2a)

The solution is:

[tex]\sqrt{\frac{(8b^2-9a^2)^2}{576a^2}-\frac{2b^2+5ab+2a^2}{12a} } -\frac{8b^2-9a^2}{24a} \\\\or\\-\sqrt{\frac{(8b^2-9a^2)^2}{576a^2}-\frac{2b^2+5ab+2a^2}{12a} } -\frac{8b^2-9a^2}{24a}[/tex]

Answer:

Step-by-step explanation:

Prime factorization requires dividing by primes starting with smallest prime number

402/2=201

201/3=67, 67 is prime so we cannot go further so the prime factorization of 402 is

2X3X67

Answer:

6 for cherry

19 for blackberry

Step-by-step explanation:

Cherry = x

Blackberry = y

Make system of equations:

Castel:

13x + y = 97

Jasmine:

6x + 3y = 93

Substitution w/ Castel's equation:

y = 97 - 13x

Put into Jasmine's equation

6x + 3(97 - 13x) = 93

6x + 291 - 39x = 93

291 - 33x = 93

-33x = -198

x = 6 $ per Cherry Pie

Plug x = 6 into any equation (choose Castel's):

13(6) + y = 97

y + 78 = 97

y = 19 $ per Blackberry Pie

**Check answers... and it's correct yay

Answer:

x=-5 & y=-2

Step-by-step explanation:

Step 1: Solve y=x+3 for y:

y=x+3

Step 2: Substitute x+3 for y  in 3x-4y =-7:

3x-4y=-7

3x-4(x+3)=-7

-x-12=-7 (Simplify both sides of the equation)

-x-12+12=-7+12 (Add 12 to both sides)

-x=5

-x/1=-5/-1 (Divide both sides by -1)

Step 3: Substitute -5  for x in y=x+3:

y=x+3

y=-5+3

y=-2 (Simplify both sides of the equation)

x=-5 and y=-2

Answer:

344

Step-by-step explanation:

Answer: 2

Step-by-step explanation:

Let's substitute the number as x in the equation.

Triple means you multiply it by 3.

Then you add four, and get 10.

We can write that like this:

3x + 4 = 10

Then subtract 4 from both sides:

3x = 6

And then divide both sides by 3:

x = 2

So the number is 2.

Answer:

4x - 5 = 24

x= 7.25

Step-by-step explanation:

4x - 5 = 24

4x= 24 + 5

x = 29 / 4 = 7.25

I hope im right!!

Answer:

[tex]Average = 30[/tex]

Step-by-step explanation:

Given

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

Required

Average [tex]rate\ of\ change[/tex] from 2 to 4

This is calculated using:

[tex]Average = \frac{f(b) - f(a)}{b - a}[/tex]

Where

[tex]a= 2[/tex]  and  [tex]b = 4[/tex]

So:

[tex]Average = \frac{f(4) -f(2)}{4 - 2}[/tex]

[tex]Average = \frac{f(4) -f(2)}{2}[/tex]

Calculate f(2) and f(4)

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

[tex]f(2) = 4^{2-1} + 2[/tex]

[tex]f(2) = 4 + 2[/tex]

[tex]f(2) = 6[/tex]

[tex]f(4) = 4^{4-1} + 2[/tex]

[tex]f(4) = 4^3 + 2[/tex]

[tex]f(4) = 66[/tex]

So:

[tex]Average = \frac{f(4) -f(2)}{2}[/tex]

[tex]Average = \frac{66 - 6}{2}[/tex]

[tex]Average = \frac{60}{2}[/tex]

[tex]Average = 30[/tex]

Answer below (dont flag people if they dont get it right, that's just messed up).

Step-by-step explanation:

The scale factor is 1.5

Answer:

t ≈ 44.43 hours

Step-by-step explanation:

Expression that models the population of a bacteria after time 't' is,

N(t) = [tex]250(e^{0.0156t})[/tex]

Here initial population = 250

And N(t) = Population after 't' hours

t = duration

We have to find the duration in which bacterial population gets doubled.

N(t) = 2×250 = 500

From the given expression,

500 = [tex]250(e^{0.0156t})[/tex]

[tex]e^{0.0156t}=2[/tex]

[tex]\text{ln}(e^{0.0156t})=\text{ln}(2)[/tex]

0.0156t[ln(e)] = 0.693147

0.0156t = 0.693147

t = [tex]\frac{0.693147}{0.0156}[/tex]

t = 44.432

t ≈ 44.43 hours

Explanation:

We have to assume the triangle is a right triangle.

In a 30°-60°-90° right triangle the side lengths have the ratio ...

  short side : long side = 1 : √3

This lets you write the proportion ...

  x/15 = 1/√3

Multiplying by 15 gives ...

  x = 15/√3 . . . . . . matching choice D

__

There are other ways to get there. One of them is ...

  x = 15·tan(30°) = 15/√3

Step-by-step explanation:

(6x+4)+(4x+26)+110°=180°{straight angle}

10x+140=180°

10x=180-140

x=40/4

x=10

(6x+4)=(6×10+4)=(60+4)=64°

(4x+26)=(4×10+26)=40+26=66°

hope it helps.

Answer:

6x+4+4x+26+110=180 straight line

10x=180-140

x=40/10=4

<A=4x+26=4×4+26=42

Answer:

50

Step-by-step explanation:

Wen: 30% of the total number of cards = 60 cards

Set this up as an equation

30/100 = 60/x

Cross multiply

30 × x = 100 × 60

30x = 6000

Divide both sides by 30 to isolate the variable

x = 200

There are 200 cards total

Gina: 25% of the total 200 cards

Set this up as an equation

25/100 = x/200

Cross multiply

25 × 200 = 100 × x

5000 = 100x

Divide both sides by 100 to isolate the variable

50 = x

Gina's share is 50 cards
