Answer:

first we know the speed from home to school is 8mph and from school to home is half that speed so 4 miles per hour

now,

from home to school it takes: m/8 hours

and from school to home m/4 hours

we can pass it to minutes multiplying by 60

so:

from home to school it takes: m*7.5 minutes

and from school to home m*15 minutes

and now the relations between these two amount of minutes is that takes 15 more from school to home so:

7.5m+17

Step-by-step explanation:

Answer:

32:35 is the ratio to your question.

Blue squares : Purple squares = 32 : 35

Ratio is defined as a relationship between two quantities, it is expressed one divided by the other.

A pattern has 32 blue squares for every 35 purple squares.

∵ 32 Blue squares : 35 Purple squares

∴ Blue squares : Purple squares = 32 : 35

The ratio of blue squares to purple squares = 32 : 35

Answer:

b.

Step-by-step explanation:

As it says there is already a set up fee of $80 and it is $4 FOR EVERY advertisement, the equation would be y = 80 + 4x. Obviously, y should be greater than x since you are calculating the cost and not anything else, so b should be your answer. Even without logically guessing, the equation proves that b is correct.

Answer:

A = $171,475, B = $119,860

Step-by-step explanation:

A represents the salary of the governor of state A.

B represents the salary of the governor of state B.

A is $51615 larger than B, so you get the equation:

A = B + 51615

The total of the two salaries is $291335, so you can the second equation:

A + B = 291335

Using the first equation, substitute the quantity (B + 51615) for A in the second equation.

(B + 51615) + B = 291335

2B + 51615 = 291335

2B = 239720

B = 119860

Plug this value of B back into either of the equations.

A = B + 51615 = 119860 + 51615 = 171475

Answer:

5/8

Step-by-step explanation:

First you need to reduce the fractions then you choose a common denominator to calculate:6/12=1/2 then you see the you see 1/4 can be a common denominator so you equal 1/2 to the denominator by 4, which means multiplying 2 by both the numerator and denominator, we get 2/4 after that you add and subtract in parentheses and you will get 1/4 then you multiply by 5 to get 5/4 the finally you have to plus 0,5 you will get 7/4 done.

The measurement which is closest to the length of the diagonal of this rectangle in centimeters is; 20 centimetres.

The diagonal of the rectangle is the line which divides the rectangle into 2 right angled triangles.

In essence, the diagonal of the rectangle is the hypothenus of either of the triangles and can be evaluated as follows;

By Pythagoras;

Answer:

a) 1,144 rad/min

b) 182.1 rev/min

Step-by-step explanation:

d= 24 inches

radius = 24/2 or 12 inches

speed = 13mi/h

need to convert speed to inches/min

v = Θ * r

1 mile = 63360 inches, and 1 hour = 60 min

13 mi * (63360 in / mi)

= 823680 in /  (1 hr * 60 min / hr)

=13728 in/min

Now go back to the equation

13728  in / min = ω * 12 in

13728  /12 = Θ

1,144 rad/min

b) 1 revolution = 2π

w= Θ/2π

w= 1,144rad/ min/2pi rad

w= 182.1 rev/min

Answer: B.  k = 12.1.

C. k = 13.0.

D. k = 19.9.

Step-by-step explanation: Which values of k are solutions to the inequality k>12 are B.  k = 12.1 , C. k = 13.0 , and D. k = 19.9 because it literally says k>12 so every value of k that's solutions to the inequality k>12 have to be greater than 12. Due to this B.  k = 12.1, C. k = 13.0, and  D. k = 19.9 are the correct answer choices that you should choose and the incorrect answer choices that you shouldn't choose are A. k = 11.9, and E. k = 10.2 .

h/0.5 = 7

In step 1, he need to multiply 0.5 on both sides.

Instead, he divided 0.5 to 7 ( i.e ) 7/0.5, This is the mistake.

The correct solution,

Step 1 :

h/0.5 • 0.5 = 7 • 0.5

Step 2 :

The surface area, to the nearest square centimeter, of the given cylinder is: 182 cm²

Recall:

From the diagram given, we have:

Substitute each value into the surface area formula for a cylinder.

Surface area = 2(π)(5)(0.8) + 2(π)(5²)

Surface area = 182.212

Therefore, the surface area, to the nearest square centimeter, of the given cylinder is: 182 cm²

Answer: y = -3x - 6

Step-by-step explanation:

One way to write a linear equation is with slope-intercept form.               Slope-intercept form is y = mx + b, where m is the slope, and b is the              y-intercept.

Thus, the equation is y = -3x - 6

Hope it helps :) and let me know if you are confused anywhere.

Answer:

y = -3x - 6

Step-by-step explanation:

Insert the information into the slope-intercept form equation:

y = mx + b

In this instance, the slope is -3 and the y-intercept value is -6. Therefore, the equation of the line is y = -3x - 6

Answer: 1/96059601

Don't break in

Step-by-step explanation:

First we need to find how many combinations there are.

We can find that by multiplying the four different number of options which in this case are all 99.

99 * 99 * 99 * 99

= 96059601

There are 96059601 different combinations and one correct combination.

Answer:

(a) 55

(b) 63

(c) 45

Step-by-step explanation:

All four angles in a rectangle are right angles, so ∠PMN is 90∘.

∠PMN+35∘=90∘

which is the same as saying

∠PMN=90∘−35∘.

Thus, ∠PMN=55∘.

and (b) is the same so:

∠STU is 90°

∠STU = 90° − 27°

∠STU = 63°

and for (c) each angle of a square measure 90°

∠DAB= 90° − 45°

∠DAB = 45°

Answer:

2 / 3

Step-by-step explanation:

( x1, y1 ) = ( - 2, 3 )

Here,

x1 = - 2

y1 = 3

( x2, y2 ) = ( - 14, - 5 )

Here,

x2 = - 14

y2 = - 5

Formula : -

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

Slope = ( - 5 - 3 ) / ( - 14 - ( - 2 ) )

          = - 8 / ( - 14 + 2 )

          = - 8 / - 12

Slope = 2 / 3
