Which one doesn’t belong

Answer:  the left side is balanced with the right side

Step-by-step explanation:

Left side:

1 barrel (located at 2) is 1 unit from the fulcrum (triangle)         →    1(1) = 1

2 barrels (located at 1) are 2 units from the fulcrum (triangle)  →  2(2) = 4

1 barrel (located at 0) is 3 units from the fulcrum (triangle)       →  1(3) = 3    

                                                                                                       Total = 8

Right side:

1 barrel (located at 6) is 3 units from the fulcrum (triangle)       →    1(3) = 3

1 barrel (located at 8) is 5 units from the fulcrum (triangle)       →  1(5) = 5    

                                                                                                       Total = 8

The distribution of the weight on the left side equals the distribution of weight on the right side so the beam is balanced.

Answer:

C

Step-by-step explanation:

If you were to multiply 15 by 40% it would equal 6.

No. of students in 1st class= 15

No. of boys = 6

Percentage of boys = 6/15 ×100

= 2/3×100

= 40%

Answer:

-127

Step-by-step explanation:

s = 101x-41+50

80 = 101x - 4+ 50

-101x

-181 = x - 4 +50

-181 = x -54

+ 54

-127 = x

Answer:

The answer is A

Step-by-step explanation:

The first thing to do is see which two lengths of EF and FG equals EG which is 23. If you add together B's options you get -12 and if you add C's options, you get 77. So that leaves us with the options of A and D. From there, just plug in each value of x and see which one gets you the right values. Hope this helps

Answer:

Step-by-step explanation:

1) Composite functions are function of two or more functions to serve as one function. For example, given d(x) and g(x), we can write both as composite function as d(g(x)). We can call it function of a function. Hence, from the following function, the following options except option B are composite.

d(x)g(x) is the product of the two functions not a composite.

Option B is correct.

b) Given h(x) = x-1 and d(x) = 7x+3

H(3) = 3-1

H(3) = 2

d(2) = 7(2)+3

d(2) = 14+3

d(2) = 17

h(3)+d(2) = 2+17

h(3)+d(2) = 19 (option D)

c) Given t(x) = -x² + 7x + 1 and r(x) = 5x² - 2x + 8, we are to first find the function

t(x)-r(x)

t(x)-r(x) = -x²+7x+1-5x²+2x-8

t(x)-r(x) = -x²-5x²+7x+2x+1-8

t(x)-r(x) = -6x²+9x-7

Substitute x as 2

(t-r)(2) = -6(2)²+9(2)-7

t-r (2) = -6(4)+18-7

(t-r)(2) = -24+11

(t-r)(2) = -13 (option C)

d) If h(x) = 4x + 2 and g(x) = 3x - 1,

h-g = 4x+2-(3x-1)

h-g = 4x+2-3x+1

h-g = 4x-3x+2+1

h-g = x+3

h-g(4) = 4+3

(h-g)(4) = 7

e) If g(x) = x - 4 and h(x) = x + 5, we are to find f(x)h(x)

h(x)g(x) = (x-4)(x+5)

h(x)g(x) = x(x)+5x-4x-20

h(x)g(x) = x²+x-20

Hence the product of h(x) and g(x) is x²+x-20. Option D is correct

Answer:

2/21

Step-by-step explanation: Basically divide both numbers by two over and over again till you get a odd number on either one. so 4 divided by 2 is 2, and 42 divided by 2 is 21, so i believe 2/21 is the answer. Hope this Helps!   -Conner

Answer:

n=-3

Step-by-step explanation:

To solve start with the 4n-10=-22

+10 to both sides and you get 4n=-12

Divide each side by 4 and you get n=-3

To check plug -3 in for n and you'll get the -2 once you solve it.

Answer:170

Step-by-step explanation:

34 miles times 5 days is 170 miles

Answer:

170 miles

Step-by-step explanation:

They are traveling 34 miles per day, and if they travel for 5 days, just multiply the miles per day, or 34, by the number of days, or 5.

34*5=170

Equation for mid point

Answer:

y= -1/4x - 1/4

Step-by-step explanation:

y - y1 = m(x - x1)

y - 1 = -1/4 (x -(-5/4))

y - 1 = -1/4x - 5/4

y = -1/4x - 1/4

Answer:

pretty sure you're right :)

Answer:

Oil needed for 1 cake = 1/4

So, for 5 cakes = 1/4 * 5

=> 5/4

Therefore you will require 5/4 cups of oil.

Answer:

let's see what to do buddy...

Step-by-step explanation:

To find the output of a number in a function, we must put it in the equation of the function instead of the x .

So to find output of ( x = 4 ) , we must put 4 instead of x in the equation .

Let's do it :

[tex]f(4) = 4 \times (4) + 7 \\ \\ f(4) = 16 + 7 = 23 \\ [/tex]

So the output number of ( x = 4 ) is 23 .

Answer:

[tex]Total\ Cost = \$38.97[/tex]

Step-by-step explanation:

Given

[tex]Backpack = \$36[/tex]

[tex]Sales\ Tax = 8.25\%[/tex]

Required

Determine the Total Cost

Total cost is calculated as thus

[tex]Total\ Cost = Backpack + Backpack * Sales\ Tax[/tex]

[tex]Total\ Cost = \$36 + \$36 * 8.25\%[/tex]

[tex]Total\ Cost = \$36 + \$2.97[/tex]

[tex]Total\ Cost = \$38.97[/tex]

0.0045 L

1000 ml in a L

So divide 4.5 by 1000

You get 0.0045
