On Saturday, Ashley rode her bicycle to visit Maria. Maria's house is
directly east of Ashley's. The graph shows how far Ashley was from her
house after each minute of her trip.
What was her average speed for the entire trip?

Answer:

X + 31 =(2x-8)

first remove the brackets

X+31=2x-8

(x-x)+31=2x-x-8

31 = x-8

31-8= -8-8+x

23=x

exterior angle

2x-8

(23+23)-8

46-8

exterior angle =38

Answer:

Tanya read 5 nonfiction books and 7 fiction books.

Step-by-step explanation:

Given that:

Number of books read by Tanya = 12

Points for nonfiction book = 3.5

Points for fiction book = 1.5

Total credit points received = 28

Let,

x be the number of nonfiction book read

y be the number fiction books read

According to given statement;

x+y=12     Eqn 1

3.5x+1.5y=28    Eqn 2

Multiplying Eqn 1 by 1.5

1.5(x+y=12)

1.5x+1.5y=18    Eqn 3

Subtracting Eqn 3 from Eqn 2

(3.5x+1.5y)-(1.5x+1.5y)=28-18

3.5x+1.5y-1.5x-1.5y=10

2x=10

Dividing both sides by 2

[tex]\frac{2x}{2}=\frac{10}{2}\\x=5[/tex]

Putting x=5 in Eqn 1

5+y=12

y=12-5

y=7

Hence,

Tanya read 5 nonfiction books and 7 fiction books.

7^2=49

40+49+10

40+49=89+10=99

99

Answer:

99

Step-by-step explanation:

According to PEMDAS, solve for the parenthesis first:

(4 x 10 + 7^2) + 10

(40 + 7^2) + 10

(40 + 49) + 10

89 + 10

Answer:

4.51°

Step-by-step explanation:

1 mile= 5280 feet

6 mile= 6(5280) =31680 feet

Angle of elevation is 0 where

tan 0 = 2500/ 31680 = 0.0789

Hence 0 = tan-1(0.0789) = 4.51°

Answer:

P = 17

Step-by-step explanation:

3y – 2 = y + 4

3y -2 (+2) = y + 4 (+2)

3y = y + 6

3y (-y) = y (-y) + 6

2y = 6

2y / 2 = 6 / 2

Y = 3

PR = 3y – 2

PR = 3(3) – 2

PR = 9 – 2

PR = 7

P of PQR = 4 + 6 + 7

P of PQR = 17

Step-by-step explanation:

21/20 = m/100

m = 100 * (21/20) = 105.

Answer:1)Distance covered by cyclist=3.75 miles.

Time =0.3 hours.

Speed= Distance ÷Time

Speed =3.75÷0.3=12.5 miles per hour.

2) Speed = 12.5 miles per hour, Distance = 4.5 miles .

Time = Distance ÷Speed.

Time = 4.5÷12.5=0.36 hours.

Time taken to cover 4.5 miles is 0.36 hours.

Answer: 0.36

Step-by-step explanation:

4.5 divided by 12.5

4.5 divided by 12.5 =

= 0.36

Answer:

(3,7)

Step-by-step explanation:

A function is a relation in which the members of the domain (x-values) DO NOT repeat. So, for every x-value there is only one y-value that corresponds to it. y-values can be repeated.

Answer:

X = -10/6

X = -1,666666666666667

Step-by-step explanation:

First at all you join the X's

18x-12x = 14-24

Then you simplified:

6x = -10

X = -10/6

X = -1,666666666666667

Answer:12.4 inch

Step-by-step explanation:

49.4 is the total length of the rope. And you have to equally divide it into 4 parts.

So 49.4/4

=12.4 inch(rounded off to 3 s.f from 12.35)

Answer:

(1) (x,y) - (2x, 3y)

(2) (x,y) - (x + 2, 3y)

(3) (x,y) (2x, y + 3)

(4) (x,y) - (x + 2, Y + 3)

that its

The distance and angle measure of ΔPQR are preserved by the transformation (x, y) → (x + 2, y + 3).

Triangles are three sided polygons in the two dimensional geometry. It has three vertices, three angles and three sides.

Vertices of the triangle PQR are P(2, 3), Q(3, 8) and R(7, 3).

Length of side PQ = √[(3 - 2)² + (8 - 3)²] = √26

Length of side QR = √[(7 - 3)² + (3 - 8)²] = √41

Length of side PR = √[(7 - 2)² + (3 - 3)²] = 5

If the transformation of (x, y) → (x + 2, y + 3) is done, vertices are P'(4, 6), Q'(5, 11) and R'(9, 6).

Length of P'Q' = √[(5 - 4)² + (11 - 6)²] = √26

Length of Q'R' = √[(9 - 5)² + (6 - 11)²] = √41

Length of P'R' = √[(9 - 4)² + (6 - 6)²] = 5

That is, lengths of sides are equal when the transformation is done. So since all sides are equal, angle measure will also be equal.

Hence by the transformation (x, y) → (x + 2, y + 3), the distance and angle measure of ΔPQR are preserved.
