09. Find the value of x according to the data given in the diagram.

Answer:

13.4

Step-by-step explanation:

Divide the number of meters in a mile (1,609.344) by the number of seconds in an hour (3,600): 1,609.344 divided by 3,600 equals 0.44704. One mile per hour equals 0.44704 meters per second.

Answer:

y = -3/4x + 12

Step-by-step explanation:

Use slope intercept form [ y = mx + b ], the point given, and the slope to find the y-intercept.

6 = -3/4(8) + b

6 = -6 + b

12 = b

Now input the values we are given and solved for into the formula.

y = -3/4x + 12

Best of Luck!

Answer:

6 hours.

Step-by-step explanation:

$50 - $20 = $30. $30 divided by $5 an hour = 6 hours. hope this helps

let the last number be x

we know,

[tex] \boxed{mean = \frac{sum \: \: of \: \: all \: \: observations}{number \: \: of \: \: observations} }[/tex]

So,

[tex] \hookrightarrow \: 8 = \dfrac{22 + x}{4} [/tex]

[tex] \hookrightarrow \: 8 \times 4 = 22 + x[/tex]

[tex] \hookrightarrow \: 32 = 22 + x[/tex]

[tex] \hookrightarrow \: x = 32 - 22[/tex]

[tex] \hookrightarrow \: x = 10[/tex]

therefore, the last number is 10.

[tex]\large\bf\blue{ \diamond} \rm \: \: m \: - \: 8 \: = \: - 14 \\ \\ \large\bf\blue{ \diamond} \rm \: \: m \: = \: - 14 \: + \: 8 \\ \\ \large\bf\blue{ \diamond} \rm \: \: m \: = \: - 6[/tex]

Answer:

OK mate don't freak out its easy

First things first x and y are height and base and 10cm is hypotenuse.

40degree is the angle

Now.

The sin angle is an trigonometric angle which deals with height and hypotenuse.

It's formulae is...... Sin angle =height /hypotenuse

So sin 40 = x/10

X= 10 * sin 40

X= 10*0.64

Hence x=6.4 cm

Remainder sin 40 is 0.64

Again

The cos angle is an trigonometric angle which deals with base and hypotenuse

It's formulae is...... Cos angle =base /hypotenuse

So cos 40 = y/10

Y= cos 40 *10

Y= 0.76*10

Hence y = 7.6cm

Remainder cos 40 = 0.76.

Thank you

Answer:

do not worry it is 63,9 degrees

Answer:

15 m and 20 m

Step-by-step explanation:

Let the width be x

Length = x + 5

Perimeter = 2(l + b)

70 = 2(x + 5 + x)

70/2 = 2x + 5

35 = 2x + 5

35 - 5 = 2x

30 = 2x

30/2 = x

15 = x

Length = x + 5 = 20 m

Breadth = x = 15 m

Answer:

Sqrt 80 = 4 sqrt 5

Step-by-step explanation:

Sqrt [(6-2)^2 + (4 - - 4)^2

= sqrt. (4^2 + 8^2) = sqrt (16 + 64)

= sqrt 80

= 4 sqrt 5

Answer:

None of the above please

Answer:X=-15

Step-by-step explanation:

-4x/5=12

5x-4x/5=5x12

-4x=5x12

-4x=60

-4x/-4=60/-4

x=-15

Answer:

5×-4/5x=12×5

-4x=60

x=-5

Step-by-step explanation:

1. Line l can be named as line FBD

2. B and C

3. Colinear:-A,B,C

No-Colinear:-F,B,C

4. 6

5. DE = 13

2 + 2x - 3 = 13

2x - 1 = 13

2x = 12

x = 12/2

x = 6

Answer:

The intersection of line l is AC and the intersection of line m is FD.

Intersection line means the line which passes the line by crossing it.

Answer:

h(0) = 7

Step-by-step explanation:

by saying h(0) it is asking you to plug in 0 as the x value

3(0)^2 = 0

0 + 7 = 7

Step-by-step explanation:

how many times is the money of the elder brother ?

this is the same to ask "how many times do I need to add the money of the younger brother to get the money off the older brother ?"

this is simply done by division : how many times do 56 fit into 280 ?

280 / 56 = 5

so, the elder brother has 5 times the money of the younger brother.

Answer:

56+56+56+56+56

hence

5 times

Answer:

[tex]y = \frac{3}{2} x + 2[/tex]

Step-by-step explanation:

In the slope-intercept form y= mx +b, m is the slope and b is the y- intercept.

[tex]\boxed{slope = \frac{y1 - y2}{x1 - x2} } [/tex]

Using the formula above,

[tex]slope = \frac{5 - ( - 4)}{2 - ( - 4)} [/tex]

[tex]m = \frac{5 + 4}{2 + 4} [/tex]

[tex]m = \frac{9}{6} [/tex]

[tex]m = \frac{3}{2} [/tex]

Substitute the value of m into the equation:

[tex]y = \frac{3}{2} x + b[/tex]

To find the value of b, substitute a pair of coordinates into the equation.

When x= 2, y= 5,

[tex]5 = \frac{3}{2} (2) + b[/tex]

5= 3 +b

b= 5 -3

b= 2

Thus, the equation of the line is [tex]y = \frac{3}{2} x + 2[/tex].

Answer:

∠ WOT = 85

Step-by-step explanation:

To find the measure of ∠WOT

we know that ∠UOV is 180 in the pic

so by letting ∠WOT = x

∠UOT + ∠WOT + ∠WOV = 180

30 + x + 65 = 180

95 + x = 180

x = 180-95

x = 85

so ∠ WOT = 85

Step-by-step explanation:

what do you mean lf speed is not given what we have tofind

Answer:

v = d/t, perhaps.

Step-by-step explanation:

Velocity (speed) is defined as distance traveled divided by the time it takes to travel that distance.

This gives an average speed.  For example, I'll be taking a trip tomorrow of about 150 miles.  If it takes me 3 hours, my average speed is v = 150/3 = 50 miles per hour.

That does not mean my speed is constantly 50 miles per hour; I sometimes go slower than that (maybe even stopping for red lights!), and sometimes I'll be going faster than that.

A lot of school math problems assume a constant speed.
