a man walked for some distance at 8 km /h and for an equal distance at 5km/h. the total time he took was 3 whole number 1/4 hours. find the total distance he walked.

Answer:

Expanded Expression: 1s- 0.59s

Simplified Expression : 0.41 s

Discounted Price=  $ 2.46

Step-by-step explanation:

Directions: Write two markup or markdown expressions for each problem below. Then substitute the given value for the variable and evaluate the expression.

The Discounted Price is found out after deducting the discount from the original price.

Let 100 be the sale price then the discount is 59 and the discounted price would be 100- 59= $41

Sale Price = $ s

Discount = 59% of $ s

Discounted Price = s- (100-59)/100*( $s) = 1s- 0.59s   = 0.41 s

Expanded Expression                             Simplified Expression

 1s- 0.59s                                                                      0.41 s

Find the sale price of the Smelly Cat litter, when the regular price was $6 per bag.

Sale Price = $ 6

Discount = 59% of $ 6

Discount= (59/100) $6= $ 3.54

Discounted Price= Sale Price - Discount= $6 - $ 3.54= $ 2.46

Answer:

distance between (F,G) and (H,J) = 9.02

distance between (F,H) and (G,J) = 3.8

distance between (F,J) and (G,H) = 3.8

Step-by-step explanation:

Distance between (F,G) and (H,J)

d=√(7.2−3.9)2+(10.6−2.2)2

d=√(3.3)2+(8.4)2

d=√10.89+70.56

d=√81.45

d=9.024965

Distance between (F,H) and (H,J)

d=√(2.2−3.9)2+(10.6−7.2)2

d=√(−1.7)2+(3.4)2

d=√2.89+11.56

d=√14.45

d=3.801316

Distance between (F,J) and (G,H)

d=√(2.2−3.9)2+(7.2−10.6)2

d=√(−1.7)2+(−3.4)2

d=√2.89+11.56

d=√14.45

d=3.801316

Hope this helps a lot!!

Answer:

Option A: -12x-8=10 is the correct answer.

Step-by-step explanation:

Given equation is:

-4 (3x+2) = 10

We will distribute the equation by multiplying the terms inside the brackets with -4.

Therefore,

-4*3x + 2*-4 = 10

-12x +(-8) = 10

-12x - 8 = 10

The equation -4 (3x+2) = 10 will become -12x-8=10 after distributing.

Hence,

Option A: -12x-8=10 is the correct answer.

Answer:

452.45mmm^2

Step-by-step explanation:

Step one:

Given data

outer radius R= 20mm

inner radius r= 16mm

let us find the area of the outer circle

Area= πR^2

Area= 3.142*20^2

Area= 3.142*400

Area= 1256.8 mm^2

let us find the area of the inner circle

Area= πr^2

Area= 3.142*16^2

Area= 3.142*256

Area= 804.35 mm^2

Hence the area of the section is

Area of outer- Area of inner

=1256.8-804.35

=452.45mmm^2

Answer:

Step-by-step explanation:

Let us represent:

Apple pie = a

Cherry pie = c

Peach pie = p

A bakery has three types of pie: apple, cherry, and peach.

There are four times as many apple pies as peach pies.

a = 4p

Answer Apple 40%    Cherry 50%      Peach 10%

Step-by-step explanation:  4x10=40

                                              5x10=50

                                              1x10=10

Therefore The answer Would be Apple 40%    Cherry 50%     Peach 10%

Given:

In an isosceles triangle LMN, LM=MN.

[tex]m\angle M=(3x+17)^\circ,m\angle L=(2x+36)^\circ[/tex]

To find:

The measure of the angles L, M and N.

Solution:

In triangle LMN,

[tex]LM=MN[/tex]                     (Given)

[tex]m\angle N=m\angle L=(2x+36)^\circ[/tex]   (Base angles of an isosceles triangle are equal)

Now,

[tex]m\angle L+m\angle M+m\angle N=180^\circ[/tex]

[tex](2x+36)^\circ+(3x+17)^\circ+(2x+36)^\circ=180^\circ[/tex]

[tex](7x+89)^\circ=180^\circ[/tex]

[tex](7x+89)=180[/tex]

On further simplification, we get

[tex]7x=180-89[/tex]

[tex]7x=91[/tex]

[tex]x=\dfrac{91}{7}[/tex]

[tex]x=13[/tex]

The value of x is 13. Using this value, we get

[tex]m\angle L=(2(13)+36)^\circ[/tex]

[tex]m\angle L=(26+36)^\circ[/tex]

[tex]m\angle L=62^\circ[/tex]

Similarly,

[tex]m\angle M=(3(13)+17)^\circ[/tex]

[tex]m\angle M=(39+17)^\circ[/tex]

[tex]m\angle M=56^\circ[/tex]

And,

[tex]m\angle N=m\angle L[/tex]

[tex]m\angle N=62^\circ[/tex]

Therefore, the measure of angles are [tex]m\angle L=62^\circ,m\angle M=56^\circ,m\angle N=62^\circ[/tex].

Answer:

15,211 feet

Step-by-step explanation:

According to the question,  given data are as follows:

Airplane altitude = 14,690 feet above

Submarine depth = 521 feet below

So, let the difference between these two elevation be d,

So, we can calculate difference by using following formula:

Difference = Airplane altitude + Submarine depth

By putting the value, we get

Difference = 14,690 + 521

= 15,211 feet

use distributive property

0.5 x -10 = -5

0.5 x k = 0.5k

0.5(-10 + k) = 0.5k -5

Answer:

m=13/7

Step-by-step explanation:

the equation for slope (m) is (y2-y1)/(x2-x1)

the given points are (0,5) and (-7,-8)

we can label them:

x1=0

y1=5

x2=-7

y2=-8

now substitute into the equation

m=(-8-5)/(-7-0)

m=-13/-7

m=13/7

the slope is 13/7

Answer:

A: 6x^8y^5

B: 4x^4z^8

C:12a^9b^7

D:6s^9t^3

Step-by-step explanation:

When you multpily exponents with the same base you just add them

You still multiply the real numbers like you normally would though

so we have

3x²y^4*2x^6y

To do this you multiply 3*2=6

add the exponents on x^2 and x^6=x^8

and add the exponents on y (which is equal to y^1) and y^4=y^5

put these together and get 6x^8y^5

B: I won't explain it twice because it's the same process

I get 4x^5z^8

C: 12a^9b^7

D: 6s^9t^3

                                                    Question 1

Given the sequence

31, 61, 91, 121,...

An arithmetic sequence has a constant difference 'd' and is defined by  

[tex]a_n=a_1+\left(n-1\right)d[/tex]

computing the differences of all the adjacent terms

61 - 31 = 30, 91 - 61 = 30, 121 - 91 = 30

The difference between all the adjacent terms is the same and equal to

d = 30

As the first term of the sequence is:

a₁ = 31

now substituting a₁ = 31 and d = 30 in the nth term of the sequence

[tex]a_n=a_1+\left(n-1\right)d[/tex]

[tex]a_n=30\left(n-1\right)+31[/tex]

[tex]a_n=30n+1[/tex]

Now, putting n = 36 to determine the 36th term

[tex]a_n=30n+1[/tex]

[tex]a_{36}=30\left(36\right)+1[/tex]

[tex]a_{36}=1080+1[/tex]

[tex]a_{36}=1081[/tex]

Thus,  the 36th term is:

[tex]a_{36}=1081[/tex]

                                               Question 2

Given the sequence

-34, -44, -54, -64, ...

An arithmetic sequence has a constant difference 'd' and is defined by  

[tex]a_n=a_1+\left(n-1\right)d[/tex]

computing the differences of all the adjacent terms

[tex]-44-\left(-34\right)=-10,\:\quad \:-54-\left(-44\right)=-10,\:\quad \:-64-\left(-54\right)=-10[/tex]

The difference between all the adjacent terms is the same and equal to

[tex]d=-10[/tex]

As the first term of the sequence is:

a₁ = -34

now substituting a₁ = -34 and d = -10 in the nth term of the sequence

[tex]a_n=a_1+\left(n-1\right)d[/tex]

[tex]a_n=-10\left(n-1\right)-34[/tex]

[tex]a_n=-10n-24[/tex]

Now, putting n = 26 to determine the 36th term

[tex]a_n=-10n-24[/tex]

[tex]a_{26}=-10\left(26\right)-24[/tex]

[tex]a_{26}=-260-24[/tex]

[tex]a_{26}=-284[/tex]

Thus, the 26th term is:

[tex]a_{26}=-284[/tex]
