Answer:

875 ft²

Step-by-step explanation:

Finding area of similar rectangles:

Scale factor = EF : AB

= 25 : 5

= 5 : 1

$\sf \dfrac{Area \ of \ bigger \ rectangle}{Area \ of \ smaller \ rectangle}= (Scale \ factor)^2$

$\dfrac{Area \ of \ bigger \ rectangle}{35} =\left(\dfrac{5}{1}\right)^2$

$\text{Area of bigger rectangle = $\dfrac{25}{1}*35$}$

Area or rectangle EFGH = 875 ft²

How much cashews at $1.58 per pound must be mixed with walnuts that cost 78 cents per pound to make a mixture of 40 pounds of nu

Likurg_2 [28]

Number of pounds of cashews is 36 pounds and number of pounds of walnuts is 4 pounds.

Step-by-step explanation:

Step 1: Given details are cost of cashews = $1.58, cost of walnuts = 78 cents = $0.78, total weight of nuts = 40 pounds, cost of nuts per pound = $1.50

Step 2: Let number of pounds of cashews to be mixed be C, then number of pounds of walnuts will 40 - C. Form equation with these variables.

⇒ 1.58 C + (40-C) 0.78 = 40 × 1.50

⇒ 1.58 C + 31.2 - 0.78 C = 60

⇒ 1.58 C - 0.78 C = 60 - 31.2

⇒ 0.8 C = 28.8

⇒ C = 36 pounds

Step 3: Calculate number of pounds of walnuts

⇒ Number of pounds of walnuts = 40 - C = 4 pounds

GIVING 20 POINTS AND A BRAINLIEST!!!! (Really need help please!)

Murljashka [212]

Answer:

Step-by-step explanation:

General form of quadratic equation:

ax^2+bx+c=0

ax^2+bx=-c

To complete the square, we will divide the coefficient of x in the general quadratic equation as written above and divide by 2

I'm the question;

x^2-20x+13=0

x^2-20x=-13

The coefficient of x =-20

Divide the coefficient by 2 and square the result afterwards

-20/2= - 10

(-10)^2= 100

Add 100 to both sides of the equation

x^2-20x+100=-13+100

x^2-20x+100=87

x^2-10x-10x+100=87

x(x-10)-10(x-10)=87

(x-10)(x-10)=87

(x-10)^2=87

Answer is 10,87
