Answer:

680 km/hr

Step-by-step explanation:

[tex]\frac{2720 km}{4 hr}[/tex]=680 km/hr

Answer:

680 km/hr

Step-by-step explanation:

Given,

Distance ( d ) = 2720 km

Time ( t ) = 4 hours

To find : -

Average speed = ?

Formula : -

Average speed = d / t

Average speed

= 2720 / 4

= 680 km/h

Answer:

Your slope is 1

Step-by-step explanation:

This is because you go up two boxes and to the right two boxes but then you have to simplify giving you a slope of 1

Answer:

720 mL ; 1080 ml

Step-by-step explanation:

Givenn:

Apple syrup : water = 2 : 3

Fruit juice volume made using the ratio above = 1800 ml

Sum of ratio = 2 + 3 = 5

Litres of Apple syrup :

(Syrup ratio / total) * total volume of fruit

(2 / 5) * 1800

= 0.4 * 1800

= 720 ml

Litres of water :

(water ratio / total) * total volume of fruit

(3 / 5) * 1800

= 0.6 * 1800

= 1080 ml

Answer:

Y-intercept is (0,8)

Step-by-step explanation:

Firstly, we need to get the equation of the line segment

We have the general equation as;

y = mx + b

m is the slope and b is the y-intercept

So for the slope between (9,6) and (-2,-1); we have

m = (y2-y1)/(x2-x1)

m = (-1-6)/(-2-9) = -7/-11 = 7/11

Mathematically, when two lines are perpendicular, their slopes have a product of -1

Let the slope of the second line be m

m * 7/11 = -1

7m = -11

m = -11/7

The equation of the second line is;

y = mx + b

y = -11x/7 + b

The line passes through the point (3.5,2.5)

So,

2.5 = -11/7(3.5) + b

2.5 = -5.5 + b

b = 2.5 + 5.5

b = 8

so the y-intercept of the perpendicular bisector is 8

Answer:

Y = 4/3 - 1

Step-by-step explanation:

(3, 3)    (0, -1)

m = 3+1/ 3-0

4/3 is the slope

Answer:

4

Step-by-step explanation:

Answer:

g(f(-9))=4

Step-by-step explanation:

This is a composite function so we need to first find the value of the function on the inside in order find the value of the composite function

f(-9)=x+7=-9+7=-2

we can put -2 instead of f(-9) in the composite function

g(-2)=(-2)^2=4

Step-by-step explanation:

1. EG=tangent line

2.EN=radius

3. ER=chord

4. IR=diameter

5.IW=secant line

6. Point E=point of tangency

7.IEW=Major arc

8. IE=minor arc

9.IER=semi-circle

10. Point N=center of a circle.

Answer:

1.55 feet.

Step-by-step explanation:

From the question given above, the following data were obtained:

Angle R = 24°

Hypothenus = RS = 3.8 feet

Opposite = ST = x

The value of x can be obtained by using the sine ratio. This is illustrated below:

Sine R = Opposite / Hypothenus

Sine 24 = x / 3.8

Cross multiply

x = 3.8 × Sine 24

x = 3.8 × 0.4067

x = 1.55 feet

Thus, the Lenght ST is 1.55 feet.

Answer:

Q1 = 61

Q3 = 63

Step-by-step explanation:

From the plot attached :

Data obtained is :

Temperature frequency

59 0

60 2

61 3

62 3

63 4

64 2

65 1

Frequency Total 15

Data in raw format :

60,60,61,61,61,62,62,62,63,63,63,63,64,64,65

The first quartile :

Q1 = 1/4(n+1)th term

n = 15

Q1 = 1/4(15+1)th term

Q1 = 1/4 * 16th

Q1 = 4th term

Q1 = 61

Third quartile (Q3):

Q3 = 3/4(n+1)th term

n = 15

Q3 = 3/4(15+1)th term

Q3 = 3/4 * 16th

Q3 = (48/4)th term

Q3 = 12th term

Q3 = 63

Answer:

Q1 is 61 and Q3=63

Answer:

4π

Step-by-step explanation:

Periodic graphs repeat the same pattern.  Here we have a cosine function which clearly repeats itself.  Start at (0, 1) and count the number of squares to the right before the graph looks the same; this occurs at (4π, 1).  x has increased from 0π to 4π.  Thus, the period is 4π.
