Answer:

The area of the circle is 379.94 mm²

Step-by-step explanation:

To solve this problem we need to use the area formula of a circle:

a = area

r = radius = 11 mm

π = 3.14

a = π * r²

we replace with the known values

a = 3.14 * (11 mm)²

a = 3.14 * 121 mm²

a = 379.94 mm²

Round to the nearest tenth

a = 379.94 mm² = 379.9 mm²

The area of the circle is 379.9 mm²

Vilka [71]

Answer:

Infinitely many solutions

Step-by-step explanation:

Step 1- Distribute into the parenthesis.

2x+12= 2(x+6)

2x+12= (2)x+(2)6

Step 2- Multiply

2x+12= 2x+12

Since they are equal, they are infinite.

Help please it would help my grade alot

Alexxandr [17]

Answer:

It cooled 58.4 degrees

Step-by-step explanation:

T(t) = 68 + 144e ^(-.052t)

We want to find the value when t= 10

T(10) = 68 + 144e ^(-.052*10)

= 68 +85.611

T(10) =153.611

We also need to know

T(0)= 68 + 144e ^(-.052*0)

=68+144

=212

We want to know how much it cools

That would be the temperature at time 0 minus the temperature at time 10

T(0) - T (10)

212-153.611

58.389

To the nearest tenth

58.4 degrees

Given H(6,7) and I (-7,-6) if point G lies 1/2 of the way long line segment HI, Santiago argues that point G is located at the o

amid [387]

A point that is half way of line segment is the midpoint

Let (6, 7) be (x₁, y₁) and (-7, -6) be (x₂, y₂)

Mid point of HI = ( $\frac{x_1+x_2}{2}, \frac{y_1+y_2}{2}$ )
Mid point of HI = ( $\frac{6+-7}{2}, \frac{7+-6}{0})$
Mid point of HI = ( $- \frac{1}{2} , \frac{1}{2}$ )

Santiago's statement is not correct

nshs = sshs+5

wshs = nshh + 6 = sshs + 11

So nshs + wshs + sshs = 3*sshs + 16

So sshs = 10, nshs = 15 and wshs = 21

Answer 15.
