Answer:

60.4miles/hr

Step-by-step explanation:

Given parameters:

 Distance covered by the car = 145miles

 Time taken  = 2.4hrs

Unknown:

Average speed of the car  = ?

Solution:

Average speed is the rate of change of distance with time;

   Average speed  = [tex]\frac{distance}{time}[/tex]

Input the parameters and solve;

   Average speed  = [tex]\frac{145}{2.4}[/tex]  = 60.4miles/hr

x = 57.59

Step-by-step explanation:

979 * 1 / 17

x = 57.59

cross multiply then divide.

if you want to be thorough and make the equation

17x = 979(1)

x = 57.59  

Answer:  (10) 3.2   (11) option 2   (12) option 4  

               (13) Distributive  (14) Associative

Step-by-step explanation:

10) "Absolute value" makes the number positive.

       - |-4| + |-7.2|

   =  -  4  +  7.2

   =       3.2

11) "Opposite" changes the sign.

    the opposite of   [tex]-\sqrt{\dfrac{2}{5}}[/tex]     is     [tex]+\sqrt{\dfrac{2}{5}}[/tex]

12) Reciprocal means "flip" the fraction

     the reciprocal of    [tex]-\sqrt{\dfrac{2}{5}}[/tex]     is    [tex]-\sqrt{\dfrac{5}{2}}[/tex]

13) a(b + c) = ab + ac    is the Distributive Property

     [tex]-\sqrt5(2+X)[/tex]

 =  [tex]-\sqrt5(2) -\sqrt5(X)[/tex]

 =  [tex]-2\sqrt5 -X\sqrt5[/tex]

14) a · (b · c) = (a · b) · c     is the Associative Property

    [tex]20(4\sqrt5)[/tex]

  = [tex](20\cdot 4)\sqrt5[/tex]

Answer:

Option (1)

Step-by-step explanation:

Lines X and Y are intersecting at a point.

Two pairs of vertical angles have been formed at the point of intersection.

1). ∠1 and ∠3

2). ∠2 and ∠4

It's given that m(∠1) = m∠3 = 55° [Since pair of vertical angles are equal in measure]

If line Y is rotated 5° clockwise about the point of intersection of both the lines,

∠1 and ∠3 both will increase by 5°.

Therefore, measure of angles 1 and angle 3 will become (55° + 5° = 60°).

Option (1) will be the answer.

The new measure of angle 3 is 60 degrees

When a point or line is rotated, it must be rotated about a point of rotation

The angle measure is given as:

[tex]\angle 1 = 55^o[/tex]

By vertical angle theorem, we have:

[tex]\angle 3 = \angle 1[/tex]

So, the angle measure becomes

[tex]\angle 3 = 55^o[/tex]

The angle of rotation is given as: 5 degrees.

So, the new measure of angle 3 is:

[tex]\angle 3 = 55^o + 5^o[/tex]

[tex]\angle 3 = 60^o[/tex]

Hence, the new measure of angle 3 is 60 degrees

Yes, the shape I can onto shape II by a sequence of transformations.

Two images are given we have to determine that whether any of shape can onto other shapes.

A graph can be defined as a pictorial representation or a diagram that represents data or values.

The shape I can be mapped into shape II through a series of transformations.

The first sequence would involve translating shape I 8 units up and 4 units left, reflecting shape I across the x-axis, then rotating shape I 90 degrees counterclockwise about the origin.

Therefore, the shape I can onto shape II by a sequence of transformations.

Answer:

The area of the triangle DEF is 10.

Step-by-step explanation:

Area of a Triangle:

A triangle of base B and height H (both must be perpendicular) has an area of:

[tex]\displaystyle A=\frac{BH}{2}[/tex]

The image below shows the triangle formed by the points DEF. It's important to notice the points E and F lie on the same horizontal line because they both have the same y-coordinate.

This fact simplifies the calculations since we can easily compute the length the of base as the difference of their x-coordinates:

B=3-(-2)=3+2=5

Being the base of a horizontal line, the height of the triangle can be calculated as the difference of y-coordinates of D and the height of that line.

H=2-(-2)=4

With these two values, we calculate the area:

[tex]\displaystyle A=\frac{5*4}{2}=10[/tex]

The area of the triangle DEF is 10.

Answer:

62.75

Step-by-step explanation:

two pairs of shoes 20 each equals 40 bucks plus 14.50 equals 54.50 plus 8.25 equals 62.75

Answer/Step-by-step explanation:

1. Perimeter of the building = sum of all the length of the outer borders surrounding the building = 1,718 ft

Thus:

4x - 6 + 2x + 3x + 2(3x + 4) + 3x + 2x + x + x + x + 2x + 4x - 6 + 2(3x + 4) + 4x - 6 + 3x = 1,718

Open the Parentheses

4x - 6 + 2x + 3x + 6x + 8 + 3x + 2x + x + x + x + 2x + 4x - 6 + 6x + 8 + 4x - 6 + 3x = 1,718

Combine like terms

42x - 2 = 1,718

42x = 1,718 + 2

42x = 1,720

x ≈ 41

2. Missing perimeter of Building = 2x + 2x + 4x - 6

Simplify

= 8x - 6

Plug in the value of x

= 8(41) - 6

= 322 ft

3. Area of English Building = length * width

= (4x - 6 + 2x)(3x)

Simplify

= (6x - 6)(3x)

Plug in the value of x

= (6(41) - 6)(3(41))

= (246 - 6)(123)

= (240)(123)

= 29,520 ft²

Answer:

Step-by-step explanation:

Step 1:

- ( 5z + 12 ) = 18     Equation

Step 2:

- 5z - 12 = 18      Open Parenthises

Step 3:

- 5z = 30     Add 12 on both sides

Step 4:

z = 30 ÷ - 5     Divide

Answer:

z = - 6

Hope This Helps :)

Answer: z = -6

Step-by-step explanation:

Hi there! I will be showing you how to solve the given equation. If you have any questions feel free to comment it down below.

Step 1: Remove parentheses.

-5z - 12 = 18

Step 2: Add 12 to both sides.

-5z = 18 + 12

Step 3: Simplify 18 + 12 to 30.

-5z = 30

Step 4: Divide both sides by -5.

z = [tex]-\frac{30}{5}[/tex]

Step 5: Simplify [tex]\frac{30}{5}[/tex] to 6.

z = -6

k is equal to 6

p is equal to 2 and -2 both

It’s either b or c

It either of those.

Answer:

3

Step-by-step explanation:

The sides are congruent so you can write the equation (4x+9)=21.

Now you subtract 9 from 21 and you get 4x=12.

All you gotta do now is divide and you get x=3.

Step-by-step explanation:

you multiply the exponents which results in 21 and then you do 4^21 which gets 4398046511104

Step-by-step explanation:

we know that midpoint of a segment is found from formula

x=(x1+x2)/2

and y=(y1+y2)/2

in this case x=3 and y=4 x2=-1 and y2=2

so x1=2x-x2 =2*3-(-1)=6+1=7

y1=2y-y2=2*4-2=8-2=6

the other endpoint is (7,6)
