Answer:

The coordinates of B is (4,1)

Step-by-step explanation:

You can use the formula of mid-point. It is given that the midpoint of AB is (4,5). So you have to substitute the coordinates of A into the formula :

m = ( \frac{x1 + x2}{2} , \frac{y1  + y2}{2} )

Let M be (4,5),

Let (x1,y1) be A(4,9),

Let (x2,y2) be B coordinates,

(4 ,5) =  ( \frac{4 + x}{ 2} , \frac{9 + y}{2} )

Then you could solve it :

\frac{4 + x}{2}  = 4

4 + x = 8

x = 4

\frac{9 + y}{2}  = 5

y + 9 = 10

y = 1

A regular pentagon has an apothem of 7.3 inches and a perimeter of 53 inches. What is the area of the pentagon? Round your answe
zvonat [6]

Answer:

Area pf the regular pentagon is 193inch^{2} to the nearest whole number

Step-by-step explanation:

In this question, we are tasked with calculating the area of a regular pentagon, given the apothem and the perimeter

Mathematically, the area of a regular pentagon given the apothem and the perimeter can be calculated using the formula below;

Area of regular pentagon = 1/2 × apothem × perimeter

From the question, we can identify that the value of the apothem is 7.3 inches, while the value of the perimeter is 53 inches

We plug these values into the equation above to get;

Area = 1/2 × 7.3× 53 = 386.9/2 = 193.45 which is 193inch^{2} to the nearest whole number

Scorpion4ik [409]
The answer would be 1.40. The 3 significant figure are 1.39 and it wants us to round so we look at the 8 in 1.3981 and since 8 > 5 we know to round up.

OAB is a sector of a circle <br>what is the area of the sector
oee [108]

Answer:

12.56 square cm

Step-by-step explanation:

Central \:angle \:(\theta) = 40°\\Radius \: (r) = 6 cm

Let A be the area of the sector of circle.

\therefore \: A =  \frac{\theta }{360 \degree}  \times \pi {r}^{2}  \\  \\=  \frac{ 40 \degree}{360 \degree}  \times 3.14\times {6}^{2}  \\  \\    =   \frac{ 1}{9}  \times 3.14 \times  36 \\  \\  =   3.14 \times 4 \\ \\ = 12.56 \:  {cm}^{2}

Answer:

In one hour Stephanie earns $1.50 more than Marco

Step-by-step explanation:

w=9h

H is a variable

9×hour= wage

9×15= $135

9×18= $162

157.50-135=$22.50

189-162=$27

27-22.50=4.50

Now cause its per hour we know she earns $4.50 more in 3 hours.

4.50÷3=$1.50
