Answer:

4

Step-by-step explanation:

28/7=4

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.

Step-by-step explanation:

0.0045 L

1000 ml in a L

So divide 4.5 by 1000

You get 0.0045

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:

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:

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:

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:

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:

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:

[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]

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:

x = 28

Step-by-step explanation:

If AB and CD are the straight lines, sum all the angles formed at a point lying on this line will be 180°.

m∠COE + m∠EOF + m∠FOB + m∠BOD = 180° [Angles at a point O on line AB]

3x + x + (x + 12) + m∠BOD = 180°

m∠BOD = 180° - (5x + 12)

Similarly, m∠AOD + m∠AOC = 180°

152° + m∠AOC = 180°

m∠AOC = 28°

Since, ∠AOC and ∠BOD are the vertical angles,

m∠AOC = m∠BOD

180° - (5x + 12)° = 28°

5x + 12 = 180 - 28

5x = 140

x = 28

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:

a. Graph A: Cost vs Volume

Graph B: Calories vs Volume

b. Graph B (Calories vs Volume)

c. k = 15

Step-by-step explanation:

a. It is not possible for a volume of 10 oz of drink to be sold for $150. It doesn't make common sense. Also, calorie level of 150 in 10 oz of drink seem plausible.

It makes more sense if 10 oz of the drink cost $3.75. Therefore, the graphs should be titled as follows:

Graph A: Cost vs Volume

Graph B: Calories vs Volume

b. The quantities in Graph B (Calories vs Volume) appear to be in a proportional relationship. We know this because if we try drawing a line to connect the points on the graph, it will give us a straight line. A straight line connotes proportionality.

Also the ratio of the quantities of the two known points given are the same. I.e. [tex] \frac{150}{10} = \frac{360}{24} = 15 [/tex]

Therefore the quantities compared in Graph B shows a proportional relationship.

c. Constant of proportionality = [tex] \frac{150}{10} = \frac{360}{24} = 15 [/tex]
