Answer:

The total area (including the area of the circle) would be 16 × 16 = 256 square centimetres.

The area of the circle would be (taking the value of pi as 3.14) is 200.96 square centimetres

The area of the shaded region would be 256 - 200. 96 = 55.04 square centimetres

Answer:

Proportional relationship:

y = kx

Use a pair of points (0.14, 0.7) to find the value of k:

0.7 = 0.14k
k = 0.7/0.14
k = 5

The function is:

y = 5x

Fill in the table:

x = 3.1 ⇒ y = 5*3.1 = 15.5
x = 2.5 ⇒ y = 5*2.5 = 12.5
x = 1.2 ⇒ y = 5*1.2 = 6
x = 0.9 ⇒ y = 5*0.9 = 4.5
y = 0.3 ⇒ x = 0.3/5 = 0.06
y = 0.1 ⇒ x = 0.1/5 = 0.02

Answer:

150 one point throws, 165 two points throws and 110 three points throws

Step-by-step explanation:

Let x be the number of free (one point) throws.

The number of free throws Sarah made was 15 less than the number of two-point field goals she made. If y is the number of two points throws, then

$x=y-15$

so the number of two points throws $=x+15$

The number of two-point field goals that Sarah made was 55 less than double the number of three-point field goals she made. If z is the number of three points throws, then

$y=2z-55\\ \\2z=y+55\\ \\2z=x+15+55\\ \\2z=x+70\\ \\z=\dfrac{1}{2}x+35$

so the number of three points throws $=\dfrac{1}{2}x+35$

The total score is 810 points, so

$x\cdot 1+(x+15)\cdot 2+\left(\dfrac{1}{2}x+35\right)\cdot 3=810\\ \\x+2x+30+1.5x+105=810\\ \\4.5x=810-30-105\\ \\4.5x=675\\ \\x=150\\ \\x+15=150+15=165\\ \\\dfrac{1}{2}x+35=\dfrac{1}{2}\cdot 150+35=75+35=110$
