Answer:

3.s is 3 times the age of Sydney's which is equals to Luke age + 5            

Step-by-step explanation:

Given Sydney’s age, s

and also Luke is 5 years younger than 3 times Sydney’s age.

Sydney's 3 times age is 3.s

Luke age = Sydney's 3 times age - 5

Luke age=3.s-5 ⇒ 3.s = Luke age + 5

Hence, 3.s is 3 times the age of Sydney's which is equals to Luke age + 5

What is the area of the figure below? Use 3.14 for pi. Round your answer to the nearest hundredth.
sammy [17]

Answer:

area of the figure ≈61.23 cm² to the nearest hundredth

Step-by-step explanation:

To find the area of the figure, we will follow the steps below;

Looking at the figure, we will see that the figure comprises of both semi-circle and a parallelogram

area of figure = area of semicircle + area of parallelogram

first, we will find the area of the semi-circle

area of a semi-circle = πr² /2

from the diagram given, diameter = 7cm

but diameter = 2r, this implies that radius r = d/2, hence radius r = 7/2 = 3.5 cm

π = 3.14

Lets insert the values into the formula

area of a semi-circle = πr² /2

                                    =3.14×3.5² /2

                                    =3.14×12.25 /2

                                     =19.2325 cm²

Area of a parallelogram = b×h

where b = base and h = height

from the figure given, base b = 7cm   and height h = 6 cm

Lets insert the values into the formula

Area of a parallelogram = b×h

                                       = 7×6

                                       =42 cm²

area of the figure = area of semicircle + area of parallelogram

                                =19.2325 cm²   +   42 cm²

                                =61.2325 cm²

                                ≈61.23 cm² to the nearest hundredth

area of the figure ≈61.23 cm² to the nearest hundredth

Find the distance between the points ( – 9, – 4) and ( – 4,8).
Dmitriy789 [7]

Answer:

Distance=13\ units

Step-by-step explanation:

<u><em>Distance between two points:</em></u> Distance between two pints (x_1,y_1)\ and\ (x_2,y_2) is given by

d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

Distance between (-9,-4)\ and\ (-4,8).

d=\sqrt{(-4-(-9))^2+(8-(-4))^2}\\\\d=\sqrt{(-4+9)^2+(8+4)^2}\\\\d=\sqrt{(5)^2+(12)^2}=\sqrt{25+144}\\\\d=\sqrt{169}\\\\d=13

Pie

Line BE and KE are the same length, so set the 2 equations to equal and solve for P.

7p+7 = 37-3p

Add 3 p to both sides:

10p +7 = 37

Subtract 7 from each side:

10p = 30

Divide both sides by 10:

p = 30/10

p = 3

The answer is B.
