Answer:

161.1 m² (1 dp)

Step-by-step explanation:

Area of a triangle = 1/2 x base x height

⇒ area = 1/2 x 12 x (20 - 12) = 48 m²

Area of a quarter circle = $\dfrac14\pi r^2$

⇒ area = 1/4 x $\pi$ x 12² = 113.1 m² (1 dp)

Total area = 48 + 113.1 = 161.1 m² (1 dp)

Three odd-shaped blocks of chocolate have the following masses and center-of-mass coordinates: (1) 0.310kg , ( 0.200 m, 0.320m )

Katarina [22]

Answer:

The x coordinate is 0.047m while y coordinate is 0.081 m

Step-by-step explanation:

The coordinates of the center of the mass of the system are given as follows

$x_c=\dfrac{\sum_{i=1}x_im_i}{\sum_{i=1}m_i}\\y_c=\dfrac{\sum_{i=1}y_im_i}{\sum_{i=1}m_i}$

So from the data

m1=0.310, x1=0.20,y1=0.320

m2=0.410,x2=0.110,y2=-0.380

m3=0.210,x3=-0.300,y3=0.630

Now by substitution of the values in the above equation

$x_c=\dfrac{\sum_{i=1}x_im_i}{\sum_{i=1}m_i}\\x_c=\dfrac{x_1m_1+x_2m_2+x_3m_3}{m_1+m_2+m_3}\\x_c=\dfrac{0.310*0.2+0.410*.110+0.210*-0.3}{0.310+0.410+0.210}\\x_c=0.047m\\\\\\y_c=\dfrac{\sum_{i=1}y_im_i}{\sum_{i=1}m_i}\\y_c=\dfrac{y_1m_1+y_2m_2+y_3m_3}{m_1+m_2+m_3}\\y_c=\dfrac{0.310*0.320+0.410*-0.380+0.210*.630}{0.310+0.410+0.210}\\y_c=0.081m$

So the x coordinate is 0.047m while y coordinate is 0.081 m

Answer and get 22 pts be named brainliest and get a thank you.

bazaltina [42]

Option c 71 3/4

Step-by-step explanation:

Step 1 :

The area of a rectangle is length * breadth

Step 2 :

Given length = 15 3/8 = 123/8 (converting mixed fractions into improper fractions)

Breadth = 4 2/3 = 14/3

Step 3 :

Hence the area of the rectangle = length * breadth

= 123/8 * 14/3 = 1722/24 = 71 3/4 (converting improper fractions into mixed fractions)

Find the slope of the line that goes through: (-1, -12) and (9, 68)

dimaraw [331]

Answer:

The slope of the line is 8.

Step-by-step explanation:

The points on the straight line are:

A = (-1, -12)

B = (9, 68)

Compute the slope of the line as follows:

$m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}$

$=\frac{68-(-12)}{9-(-1)}\\\\=\frac{68+12}{9+1}\\\\=\frac{80}{10}\\\\=8$

Thus, the slope of the line is 8.

Dave is considering two loans. Loan U has a nominal interest rate of 9.97%, and Loan V has a nominal interest rate of 10.16%. If

Ierofanga [76]

Loan u
R=(1+0.0997/360)^360)-1
R=0.105*100=10.5%
Loan v
R=(1+0.1016/4)^4)-1
R==0.106*100=10.6%
Loan u is the lower by 0.1%
