There are 4 triangles and the formula for the area of a triangle is 1/2BH so 11x10 is 110 and then take half of that and you’ll get 55. Since there are 4 triangles you need to then multiply that by 4 to get 220. And then you have to find the area of the square base which is 11x11 which will come out to 121. So you add the 220 and 121 to get 341.

Express each quotient in the simplest form. 20xy^3/6z divided by 2xy/18z^5

Galina-37 [17]

$\dfrac{20xy^3}{6z}:\dfrac{2xy}{18z^5}=\dfrac{10xy^3}{3z}:\dfrac{xy}{9z^5}=\dfrac{10xy^3}{3z}\cdot\dfrac{9z^5}{xy}\\\\=\dfrac{10xy^3}{z}\cdot\dfrac{3z^5}{xy}=10y^2z^4\\\\\text{used:}\\ a^n\cdot a^m=a^{n+m}\\\\\dfrac{a^n}{a^m}=a^{n-m}$

one number is equal to the square of another. find the numbers if both are positive and their sum is 1122

statuscvo [17]

Answer:

One number is 561

The other number is 23.6854

Step-by-step explanation:

x = y^2 One number = the square of another

x + y^2 = 1122 The sum of the two numbers is 1122

Substitute y^2 in for x on the second equation.

y^2 + y^2 = 1122 Combine like terms on the left

2y^2 = 1122 Divide by 2

y^2 = 1122/2

y^2 = 561 Take the square root of both sides.

y = 23.6854

x = y^2

x = 561

y^2 = 561

multiply 500 by 4 to know how much is needed in grams first

500×4 = 2000

convert 2000grams to kilograms

since 1000grams make 1 kilograms....then divide 2000 by 1000

which would give you 2000/1000
