Answer:

let distance between the two stops be d

so

avg. speed for whole journey = total distance/total time

= ( 2d) / ( d/40 + d/50)

= 2/ (1/40+1/50)

= 2 / ( 90/ 200)

= 2× 200/90

= 40/9 mph

Answer:

3[tex]\sqrt{3}[/tex]

Step-by-step explanation:

Using Pythagoras' identity on the right triangle.

The square on the hypotenuse is equal to the sum of the squares on the other 2 sides.

let x be the length of the other leg, then

x² + 3² = 6², that is

x² + 9 = 36 ( subtract 9 from both sides )

x² = 27 ( take the square root of both sides )

x = [tex]\sqrt{27}[/tex] = [tex]\sqrt{9(3)}[/tex] = [tex]\sqrt{9}[/tex] × [tex]\sqrt{3}[/tex] = 3[tex]\sqrt{3}[/tex] ← exact value

Answer:

Step-by-step explanation:

There are many methods but I give you the factorisation:

[tex]4x^{2} +7x+6= 4x^{2} + 8x - x - 2 +8= (4x^{2} + 8x )- (x + 2) +8\\= 4x(x+2)-(x+2) -8\\=(x+2)(4x-1) +8[/tex]

So

[tex]\frac{4x^{2} +7x+6}{x+2}=\frac{(x+2)(4x-1)+8}{x+2} =\frac{(x+2)(4x-1)}{x+2}+\frac{8}{x+2}\\ \\=4x-1 +\frac{8}{x+2}[/tex]

That means the quotient is 4x-1 and the remainder is 8.

Answer:

csc x = - [tex]\frac{5}{3}[/tex]

Step-by-step explanation:

Using the trigonometric identity

csc²x = 1 + cot²x

         = 1 + (- [tex]\frac{4}{3}[/tex] )² = 1 + [tex]\frac{16}{9}[/tex] = [tex]\frac{25}{9}[/tex], thus

csc x = ± [tex]\sqrt{\frac{25}{9} }[/tex] = ± [tex]\frac{5}{3}[/tex]

Since 270° < x < 360° where csc x < 0 , then

csc x = - [tex]\frac{5}{3}[/tex]

Answer:

25.1

Step-by-step explanation:

1. Find the radius of the inner circle

(the formula for the circumference of a circle is [tex]C=2\pi r[/tex])

To find the radius of the inner circle, you would plug in the given information so that your equation looks like this:

[tex]22=2(\frac{22}{7} )r[/tex]

then solve for [tex]r[/tex]

[tex]r=3.5[/tex]

2. add [tex]4[/tex] to the radius of the inner circle

[tex]3.5+4=7.5[/tex]

3. find the circumference of the outer circle using [tex]7.5[/tex] as the radius

[tex]C=2(\frac{22}{7})7.5[/tex]

[tex]C=47.1[/tex]

4. Subtract the circumference of the inner circle from the circumference of the outer circle

[tex]47.1-22=25.1[/tex]

Answer:

Volume Con = pi x radius^2 x h/3

Volume Sphere = 4/3 x pi x radius^3

Step-by-step explanation:

Volume of shape = Volume of Cone + 1/2 x Volume of  Sphere

Volume of shape = pi x radius^2 x h/3 +1/2 (4/3 x pi x radius^3)

Volume = (3.14 x 39^2 x (81-39)/3) + 1/2(4/3 x 3.14 x 39^3)

Volume = (3.14 x 1521 x 14) + 1/2 (4/3 x 3.14 x 59319)

Volume = (66863.2) + (124174.4)

Volume = 191037.6

Volume = 191038 cubic ft

Step-by-step explanation:

Answer:

Step-by-step explanation:

In slope and intercept form it is going to be in form y=mx+c where m is the slope and c is the intercept

3x+4y=12

4y=-3x+12

Making y subject of the formula by dividing all through by 4

y=-3x/4 + 12/4

y=-3x/4 + 3

This is the equation in slope and intercept form

Answer:

y = -7x+4

Step-by-step explanation:

We can use the slope intercept form of the equation

y = mx+b where m is the slope and b is the y intercept

We know the slope

y = -7x+b

We have a point to substitute in for x and y

-3 = -7(1) +b

-3 = -7+b

Add 7 to each side

-3+7 =b

4 =b

We can substitute this back into

y = -7x+b

y = -7x+4

Answer:

y+-7x+4

Step-by-step explanation:

y-y1=m(x-x1)

y+3=-7(x-1)

y+3=-7x+7

y=-7x+4

Ted take 26 minutes to complete the puzzle.

What is mean by Subtraction?

Subtraction in mathematics means that is taking something away from a group or number of objects. When you subtract, what is left in the group becomes less.

Given that;

Ted started a puzzle at 7:17 PM.

And, It completed the puzzle at 7:43 PM.

Now,

Since, Ted started a puzzle at 7:17 PM.

And, It completed the puzzle at 7:43 PM.

So, The time to complete the puzzle = 7:43 - 7 :17

                                                         = 0:26

                                                         = 26 minutes

Thus, Ted take 26 minutes to complete the puzzle.

Answer:

(A)James is correct.There are fewer rows, so there will be more in each row. There will be  12 jelly beans in each row for 2 equal rows, and 8 jelly beans in each row for 3 equal rows.

Step-by-step explanation:

James is putting 24 jelly beans into equal rows.

If he puts the jelly beans in 2 equal rows:

Number in each row=24/2=12 jelly beans per row.

If he puts the jelly beans in 3 equal rows:

Number in each row=24/3=8 jelly beans per row.

Therefore, James is correct.There are fewer rows, so there will be more in each row. There will be  12 jelly beans in each row for 2 equal rows, and 8 jelly beans in each row for 3 equal rows.

The correct option is A.

Answer:

5

Step-by-step explanation:

The first number before the x is the slope which is the quotient of the rise and the run of the line. The number after the x is where the line intercepts the y axis which is called the y intercept.

Answer:

m= 5

Step-by-step explanation:

The line is in slope-intercept form

y=mx+b

where m is the slope and b is the y-intercept

We have the line:

y=5x-1

5 is the coefficient that comes before x, therefore 5 is the slope.

The constant being subtracted, -1, is the y-intercept

Therefore: m=5 and b=-1

The slope is 5

Answer:

m∠QPR = 20°

Step-by-step explanation:

If we make a sketch of the triangle, it will be observed, that line R bisects angle P.

Considering Triangle, ΔQPS;

∠QPS=107∘

Considering triangle, QPR;

∠QPR=9x-115∘

Considering triangle, RPS;

∠RPS=4x+27∘

Thus, ∠RPS + ∠QPR = ∠QPS

4x+27° + 9x-115° = 107°

13x - 88° = 107∘

13 x = 107∘ + 88∘

13x = 195°

x = 195°/13

x = 15°

m∠QPR = 9x - 115°

= (9 x 15) - 115°

= 135° - 115°

= 20°

Therefore, m∠QPR = 20°

Explanation:

The 14th term of the geometric sequence 1 , − 5 , 25 , . . . is (5)¹⁴ after using the geometric sequence formula.

It is defined as the systematic way of representing the data that follows a certain rule of arithmetic.

It is given that:

The sequence is:

1 , − 5 , 25 , . . .

The above sequence represents a geometric sequence.

Divergent sequences are those in which the terms never stabilize; instead, they constantly increase or decrease as n approaches infinity,

approaching either infinity or -infinity.

The common ratio = -5/1  = -5

The nth term a(n) = arⁿ⁻¹

The first term a = 1

The nth term a(n) = (5)ⁿ⁻¹

Plug n = 14

The 14th term a(14) = (-5)¹⁵⁻¹

The 14th term a(14) = (5)¹⁴

Thus, the 14th term of the geometric sequence 1 , − 5 , 25 , . . . is (5)¹⁴ after using the geometric sequence formula.

Step-by-step explanation:

1-I could tell by matching the width of the rectangle with the circumference of the lid. The width would wrap perfectly around the circle if it is the same length at the circumference.

2-The width would be different because the width is equal to the circumference.

3-First, I would find the circumference. I would do 2(h)*pi to find the circumference. I would draw two circles with this circumfrence, then I would put a rectangle in between the circles with the height as the height of the cylinder and the width as the circumference.
