Answer:

52.15

Step-by-step explanation:

you need to find how much each pint cost by itself so...

8.94 divided by 6 is 1.49

then 1.49 x 35 = 52.15

and that is your answer

$52.15

Step-by-step explanation:

i just dived 8.94 by 6 then multiplyed that answer by 35

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.

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]

Answer:

let the missing angle be x

now

x+52.49+90=180(being the sum of traingle)

or,x=180-142.49

or,x=37.51

answer

Answer:

the answer is c

Step-by-step explanation:

if you plug in 2 as x in letter c you get

y=10*2+5

10*2=20

20+5=25

Answer:

A. 6 x -1 + 16 = 10

B. 5 x  11 - 15 = 70

C. 10 x 2 + 5 = 25

D. 5 x 5 + 15 = 40

Step-by-step explanation:

I think this is right

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:

no

Step-by-step explanation:

Answer:

x = 40.5

2/3 * 40.5 = 27

Answer:

81/2

Step-by-step explanation:

divide by 2/3rds on both sides and then there is your answer

have a great night!!!

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:

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

Answer:

1/12

Step-by-step explanation:

2/3=8/12

2x4=8

3x4=12

1/4=3/12

1x3=3

4x3=12

8/12+3/12=11/12

1-11/12= 1/12

-3(X - 4) = – 3x + 12 infinite solutions

4(x + 1) = 3x + 4 one solution

-2(x-3) = 2x - 6 one solution

6(x + 5) = 6x + 11 no solution

5(x-2)=5x-7 no solution

The answer is D.

It should be 17 -1 / 18 -14

Answer:

ill come up with the answer in a little while

Step-by-step explanation:

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)

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:

v = 14/9 + 2y/9

Step-by-step explanation:

First add 2y to both sides. Then, divide both sides by 9. Now you have v isolated.

Answer: Since FK is half the line, and FH is the whole line 6*2= 12

so FH=12

Answer:

it would be 12

since FK would be the same measurement as KH so all u gotta do is add 6+6 and u get 12

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.
