Answer:

2.75 hours

Step-by-step explanation:

Speed is 24km per hour ([tex]\frac{24km}{1hour}[/tex]), and the bus covered 66km.

We need to get a value of km with the rate (24/1) and distance (66) given.

We get:  [tex]\frac{1hour}{24km} *66km[/tex].  

The km cancel out, leaving us with 66/24 hours, or 2.75 hours.

Answer:

4c² + 11cd + 5d

Step-by-step explanation:

To add monomials, you have to look at the variables that are accompanied by their coefficients. In the given problem, (–4c2 + 7cd + 8d) + (–3d + 8c2 + 4cd), you can combine both cd ut nt cd and c² and cd and d and d and c² because they have different variables.

(–4c2 + 7cd + 8d) + (–3d + 8c2 + 4cd)  

(-4c² + 8c²) + (7cd + 4cd) + (8d - 3d)

4c² + 11cd + 5d

Answer:

C, D, E

Step-by-step explanation:

Remote angles theorem; when one side of a triangle is extended, the angle formed must equal the sum of the two angles in the triangle, that it isn't adjacent to.

C. (m<4) > (m<1), this has to be true because of remote angles theorem.

(m<4) must be greater than (m<1) because it is equal to (m<1) + (m<2)

D. (m<4) > (m<2), apply the same logic here, as was applied to the first problem.

E. (m<1) + (m<2) = (m<4), this is essentially remote angles theorem.

Answer:

a) 31.4 cm b) 22.0 cm c) 9.4 mm d) 18.8 m e) 1.6 m f) 28.3 cm g) 78.5 cm h) 9.7 m

Step-by-step explanation:

All it really is multiply the diameter which is the straight line through the center of the circle

C = d × \pi

The circumference of the circles is A. 31.4 cm, B. 22cm approx,

C. 9.4 mm, D. 18.88 m, E. 1.6 m, F. 28.3 cm, G. 78.5 cm, H. 4.1 m.

A circle is a closed, two-dimensional object where every point in the plane is equally spaced from a central point. The line of reflection symmetry is formed by all lines that traverse the circle. Additionally, every angle has rotational symmetry around the center.

Given circles,

circumference  of circle is 2πr in form of diameter = πd

where d is diameter,

A. given d = 10 cm

circumference   = c = πd

c = 3.14 x 10

c = 31.4 cm

B. given, d = 7 cm

c= πd

c = 3.14 x 7

c = 21.98 cm = 22 cm approx

C.given, d= 3 mm

c = πd

c = 3.14 x 3

c = 9.4 mm

D. given d = 6 m

c = πd

c = 3.14 x 6

c = 18.8 m

E. given c = 0.5 m

c = πd

c = 3.14 x 0.5

c = 1.6 m

F. given d = 9 cm

c = πd

c = 3.14 x 9

c = 28.3 cm

G. given d = 25 cm

c = πd

c = 3.14 x 25

c = 78.5 cm

H. given d = 1.3 m

c = πd

c = 3.14 x 1.3

c = 4.1 m

Hence the circumference is as follows.

i just took the question and got it right on ed2020

We have to make sure the denominators are equal.

10 goes into 5 evenly, so we only need to multiply one term to get a common denominator.

Multiply 2 by 2, and get 4, then we multiply 5 by 2 and get 10

Now the equation is 4/10 + 6/10

Since our denominators match, we can add the numerators.

4 + 6 = 10

That gives us the sum, which is 10/10 aka 1 whole

your welcome :) (btw can u please give brainly?)

Answer:

2/5 + 6/10 = 1

Step-by-step explanation:

first let’s change 2/5 so it has the same denominator as 6/10.

2/5 * 2/2 = 4/10

now add

4/10 + 6/10 = 1

Answer:

The option D represents an interval with a positive average rate of change.

Step-by-step explanation:

Let [tex]f(x) = x^{2}+10[/tex], the average rate of change on the interval [tex][a,b][/tex] is represented by the definition of the secant line:

[tex]\bar f = \frac{f(b) -f(a)}{b-a}[/tex] (1)

Where:

[tex]a[/tex], [tex]b[/tex] - Lower and upper bounds, dimensionless.

[tex]f(a)[/tex], [tex]f(b)[/tex] - Function evaluated at lower and upper bounds, dimensionless.

Now we proceed to check each option:

A. [tex]a = -3[/tex], [tex]b = 3[/tex]

[tex]\bar f = \frac{19-19}{3-(-3)}[/tex]

[tex]\bar f = 0[/tex]

B. [tex]a = -4[/tex], [tex]b = -1[/tex]

[tex]\bar f = \frac{11-26}{(-1)-(-4)}[/tex]

[tex]\bar f = -5[/tex]

C. [tex]a = -3[/tex], [tex]b = 1[/tex]

[tex]\bar f = \frac{11-19}{1-(-3)}[/tex]

[tex]\bar f = -2[/tex]

D. [tex]a = -1[/tex]. [tex]b = 2[/tex]

[tex]\bar f = \frac{14-11}{2-(-1)}[/tex]

[tex]\bar f = 1[/tex]

The option D represents an interval with a positive average rate of change.

Answer:

The longest day of the year is day 172  

Step-by-step explanation:

Since the length of day is L(t)=727+22sin[2π(t−80.75)/365], the maximum length of day is obtained when sin[2π(t−80.75)/365] is at its maximum value which is 1. So. sin[2π(t−80.75)/365] = 1

We now solve this to find the day at which this maximum value occurs.

sin[2π(t−80.75)/365] = 1

[2π(t−80.75)/365] = sin⁻¹(1)

[2π(t−80.75)/365] = π/2

dividing both sides by 2π/365, we have

[2π(t−80.75)/365] ÷ 2π/365 = π/2 ÷ 2π/365

t−80.75 = 365/4

t−80.75 = 91.25

t = 91.25 + 80.75

t = 172

The longest day of the year is day 172

Answer:

172

Step-by-step explanation:

Keep in mind, that when graphed one of the "tallest" points is 172,749. Using this, you'll find that 172 is the tallest

Since n(P) = a+b = 9

c is 5-b = 5-3 = 2

Answer:

The correct option is; A. [tex]y = \dfrac{7}{4} x + 7[/tex]

Step-by-step explanation:

The given equation is 4·y - 7·x = 8

The coordinates of the point the line passes = (-4, 0)

By dividing the given equation by 4, we have;

4·y/4 - 7/4·x = 8/4

Which gives;

y  - 7/4·x = 2

y   = 7/4·x + 2

Which is the equation of a straight line in slope and intercept form, y = m·x + c, with the slope, m = 7/4, and the y-intercept = 2

Given that the required line is parallel to the graph of the equation, 4·y - 7·x = 8, the slopes of both equations are equal we have;

Slope of required line = 7/4, point on the line = (-4, 0), which gives the following point and slope form equation of a straight line;

y - 0 = 7/4 × (x - (-4))

y = 7/4·x + 7/4 × 4 = 7/4·x + 7

The equation of the line is therefore;

y = 7/4·x + 7

He sold the stock for y dollars and paid a flat fee of  $7. It means he sold y-7.

We need to find Quinton's net proceeds algebraically. It will be given as :
