diamong [38]

<em>Answer:</em>

<em>The perimeter of the larger square is $150cm.$ </em>

<em>Step-by-step explanation:</em>

<em>First of all, let one part of it be " $x$ "</em>

<em>and the other part of it " $200-x$ "</em>

<em>Now to solve this :</em>

<em>The area of the square = $L^2$ </em>

<em>The area of one part of the square = $x^2$ </em>

<em>The area of the other part of the square = $(200-x)^2$ </em>

<em> $9x^2= (200-x)^2\\9x^2=40000-400x+x^2$ </em>

<em></em>

<em>Now, add, $-4x^2$ to both the sides :</em>

<em> $9x^2-9x^2=40000-400x+x^2-9x^2\\-1(8x^2+400x-40000)=0$ </em>

<em />

<em>Now, take out the "8" which is common :</em>

<em> $-8(x^2+50x-5000)=0$ </em>

<em></em>

<em>Now, divide it by $-8$ :</em>

<em> $x^2+100x-50x-5000=0\\x(x+100)-50(x+100)=0\\(x+100)(x-50)=0\\$ </em>

<em> $x=-100$ or $50$ </em>

<em />

<em>So, now we know that :</em>

<em>One of the part is = $50cm$ </em>

<em>And the other part is = $150cm$ </em>

<em />

<em>Thus the perimeter of the larger square is = $150cm$ </em>

Alec and Kiara went to Freddy's Yogurt Shop for frozen yogurt. Alec got 8.6 ounces of strawberry frozen yogurt, and Kiara got 8.

LiRa [457]

Answer:

$8.40

Step-by-step explanation:

8.6 plus 8.2 is 16.8 so they had a total of 16.8 ounces. $0.50 per ounce so you need to multiply 16.8 by 0.50 which is 8.40. you can also do 8.6(0.5) plus 8.2(0.5)= 4.3 plus 4.1 = 8.4

At their family's pizzeria, Dave makes 6 pizzas in the first hour it is open and 3 pizzas each hour after that. Lauren makes 11

Nady [450]

Answer:

47 pizzas

Step-by-step explanation:

Dave makes 6 pizzas in the first hour it is open and 3 pizzas each hour after that.

If the number of hours after the first hour is represented as x, then the number of pizzas he makes after x hours is:

6 + 3x

Lauren makes 11 pizzas in the first hour and 3 pizzas each hour after that. Then:

11 + 3x

The pizzeria is open for 6 hours in all, that is, 5 hours after the first hour.

This means that:

x = 5

The total amount of pizzas that Dave and Lauren make is:

6 + 3x + 11 + 3x

=> 17 + 6x

Therefore, the total amount of pizza they make 5 hours after the first hour is:

17 + 6(5) = 17 + 30 = 47 pizzas
