Answer:

60/11 or 5  5/11

Step-by-step explanation:

Change to mixed numbers- 15/2 and 11/8.

multiply 15/2 by reciprocal- 15/2 x 8/11.

simplify-60/11

Answer:

x=8

Step-by-step explanation:

bc (8-7) =1,  1 time 4 = 4                  (we always do -/+ before multiplication)

 and (10-8)=2, 2 time 2 = 4

since for both you get the same result therefore x=8

(I just get that for my I-ready I was stuck for a period of time than realize it)

The answer is D.

It should be 17 -1 / 18 -14

Answer:

  Mark the lower tick marks with hour numbers; see what hour corresponds to 2/3 mile

Step-by-step explanation:

The upper number line is marked off in 1/3 mile increments.

The tick marks on the lower line divide the unit distance into 6 parts, instead of 3, so each mark on the lower line corresponds to 1/6 mile.

The problem statement tells you the completion rate is 1/6 mile per hour, so we can number the lower tick marks 0, 1, 2, 3, 4, 5, 6 hours, leaving the marks on the upper number line at 1/3 mile, 2/3 mile, and 1 mile.

Then the lower tick mark we have labeled 4 hours will correspond to the upper tick mark labeled 2/3 mile.

__

To solve the problem using number lines, mark the number lines with values that correspond. Extend the numbering as required to answer the question asked.

Answer:

1.  r =  [tex]\sqrt[3]{\frac{3v}{4\pi } }[/tex]

divide v by 4/3, this is the same as multiplying v by 3/4 so you have 3v/4

then divide v by [tex]\pi[/tex] so you now have 3v/4[tex]\pi[/tex]

then get rid of the ^3 on r by putting the solution for r under a ∛

2. a) The equation might need to be written in terms of a because you may not know the value of a, but you know the value of everything else. If this is the case then you can simply rewrite the equation so that you can plug it all into a calculator and avoid certain possible errors.

     b)

 s = ut + 1/2 [tex]at^{2}[/tex]

subtract ut from both sides: s - ut = 1/2 [tex]at^{2}[/tex]

multiply both sides by 2: 2(s - ut)

divide both sides by [tex]t^{2}[/tex]: [tex]\frac{2(s - ut) }{t^{2} }[/tex] = a

answer: a =  [tex]\frac{2(s - ut) }{t^{2} }[/tex]

I'm not entirely sure about b) for question 2 so you might wanna double check that with a friend

Answer:

Total distance covered: 60x8 = 480

Speed needed to cover distance of 480 km in 6 hrs = 480/6 = 80 km/hr.

initial velocity : 60 km/hr.

Train needs to run faster with speed of 20km per hour to achieve same distance in 6 hrs.

Answer:

Completing the square we get: [tex](x-2)^2-(2)^2[/tex]

and factoring the term we get: [tex]x(x-4)[/tex]

Step-by-step explanation:

We need to complete the square for the expression [tex]x^2-4x[/tex]

For completing the square the expression would be of form [tex]a^2+2ab+b^2=(a+b)^2[/tex]

For given expression we have to add (2)^2 and subtract to make it complete the square.

[tex]x^2-2(x)(2)+(2)^2-(2)^2\\(x-2)^2-(2)^2[/tex]

Now, we have to factor the polynomial using formula [tex](a)^2-(b)^2=(a-b)(a+b)[/tex]

So, [tex](x-2)^2-(2)^2\\=(x-2-2)(x-2+2)\\=(x-4)(x-0)\\=x(x-4)[/tex]

Completing the square we get: [tex](x-2)^2-(2)^2[/tex]

and factoring the term we get: [tex]x(x-4)[/tex]

D

can i get brainly?

Answer:

E, D

Step-by-step explanation:

rate of change is the slope

slope is change in y over change in x

the slope of the graph is (3/2)

E has a slope of 1/2 which is less than 3/2

D has a slope of 1 which is also less than 3/2

Answer:

Step-by-step explanation:

You just combine common variables.

8a^5 -4

3a^5 + a -2

11a^5 + a -6

The solution to the first is 11a^5+a-6.

The second:

3x^2 -2x + 1

-x^2 + 3x + 1

2x^2 + x + 2

2x^2+x+2

Answer:

System of Equations

c + r = 32 ..... Equation 1

2c + 4r = 72......... Equation 2

We have 28 chickens and 4 rabbits

Step-by-step explanation:

Let the number of chickens be represented by c

The number of rabbits be represented by r

From the question, John counts:a total of 32 heads

32 heads = a total of 32 animals

Hence:

c + r = 32....... Equation 1

c = 32 - r

Also, John counts:

A total of 72 legs in his backyard.

Chickens have: 2 legs

Rabbits have: 4 legs

Hence:

2c + 4r = 72......... Equation 2

System of Equations is:

c + r = 32 ..... Equation 1

2c + 4r = 72......... Equation 2

Lets us substitute 32 - r for c in Equation 2

2(32 - r) + 4r = 72

64 - 2r + 4r = 72

Collect like terms

- 2r + 4r = 72 - 64

2r = 8

r = 8/2

r = 4

This means we have 4 rabbits

Note:

c = 32 - r

r = 4

c = 32 - 4

c = 28

Hence, we have 28 chickens

Step-by-step explanation:

Given :

Wall measures about 65 feet tall and 80 feet wide.

To Find :

If Os Gemeos did a sketch on paper that was 8 inches tall for one wall, how wide would their sketch have to be to stay in proportion.

Solution :

Let, width of sketch is x.

Since, they are in proportion :

[tex]\dfrac{65}{10}=\dfrac{65+8}{x}\\\\x = \dfrac{10\times 73}{65}\\\\x = 11.23\ feet[/tex]

Therefore, width of sketch should be 11.23 feet.

Hence, this is the required solution.

Answer:

210 students brought lunch

Step-by-step explanation:

At school on Friday the ratio of students who purchased a lunch to students who brought lunch was 4:3.

The ratio is

Students who purchased: Students who brought

= 4 : 3

The total proportion

= 4 + 3 = 7

The total number of students from the question is : 490

Hence, The number of students that brought lunch is calculated as:

3/7 × 490

= 210 students

Hence, 210 students brought lunch
