Answer:

1849

Step-by-step explanation:

1 - 1

2 - 4

3 - 9

4 - 16 (drew this one out)

We can see that each of the triangles is the number of the picture squared. So for the 43rd picture we take 43 * 43 = 1849

So the 43rd picture is 1849

Jane purchased a concert ticket on a web site. The original price of the ticket was $55. She used a coupon code to receive a 20%

Licemer1 [7]

Answer:

28%

Step-by-step explanation:

-The price after the coupon discount is calculated as;

$P_{ad}=P_r(1-d)\\\\=55(1-0.2)\\\\=\$44$

We reduce the discounted price by the service fee to determine the effective purchase price:

$P_f=P_{ad}(1-f)\\\\=44(1-0.1)\\\\=\$\ 39.6$

#Compare this final price to the original price:

$\bigtriangleup=1-\frac{Final}{Original}\\\\=1-\frac{39.6}{55}\\\\=0.28 \ \ or \ 28\%$

Hence, the final price was 28% less than the original price.

There are blue, red and yellow marbles in a bag. The probability of choosing a blue marble is 1/8, and the probability of choosi

Ilya [14]

Answer:

3/8

Step-by-step explanation:

So what I did is make 1/2 have a common denominator with 1/8. The common denominator would be 4/8. Then i added 1/8 and 4/8 and got 5/8. Then I subtracted 5/8 and 8/8 because 8/8 would be the 100% chance. Then I got 3/8. So I would then think the chance of getting a yellow marble would be 3/8 chance. I hope I helped :)

Factor completely. 12x4+18x3+45x2 Enter your answer in the box.

lukranit [14]

QUESTION 1

The given expression is

$12x^4+18x^3+45x^2$

The greatest common factor is $3x^2$ .

We factor to obtain;

$3x^2(4x^2+6x+15)$

QUESTION 2

The given quadratic equation is

$x^2+6x-72=0$

We split the middle term to obtain

$x^2+12x-6x-72=0$

Factor by grouping;

$x(x+12)-6(x+12)=0$

$(x+12)(x-6)=0$

Use zero product property;

$(x+12)=0\:\:or\:\:(x-6)=0$

$x=-12\:\:or\:\:x=6$

QUESTION 3

The given system of equation is

$3x+4y=-8$

$7x-3y=6$

If we multiply $3x+4y=-8$ by 3, we obtain;

$9x+12y=-24$

If we multiply $7x-3y=6$ by 4 we obtain;

$28x-12y=24$

Adding the last two equations will give us;

$37x=0$

The y-variable is eliminated.

Answer:Multiply 3x+4y=−8

by 3. Multiply 7x−3y=6 by 4. Add the resulting equations together.
