Answer:

x = 1

Step-by-step explanation:

Rewrite the equation to get x/0.6 = 5/3, since the division sign is the same thing as a slash sign and that 1 2/3 is equivalent to 5/3.  Multiply 0.6 on both sides to get 1 as your final answer.

Answer:

1

Step-by-step explanation:

0.6 times 1 2/3 is 1. in that case, 1 divided by 0.6 is 1.66666666667, also known as 1 2/3 making x = 1

Answer:

29 feet for second ladder

Step-by-step explanation: I dont think first is possibe(decimals), second 21 square+ 20 square= 441+200=881, root of 881 is 29.

Answer:

As this is a right angled triangle, simply find the hypotenuse

Step-by-step explanation:

We know that the square of hypotenuse is equal to the sum of the square of the other two sides

In formula > h²=a²+b²

We know the values of a and b.

Now simply put the values into the equation to find the answer :)

For 1,  h²= 25² + 10²

h² = 625 + 100

=725

h=√(725)

=26.92 feet

Therefore height of ladder = 26.92 feet

For 2,

h²= 21²+20²

h²=441 + 400

h² = 841

h = √841

h = 29 feet

Heigh of ladder = 29 feet

Step-by-step explanation:

here

cost of 12 liters oil = RS 4800

cost of 1liter oil =rs 4800 ÷ 12 = 400

now

cost of 20 liters will be 400×20=8000

Answer:

x = - 2

Step-by-step explanation:

(f + g)(x) = f(x) + g(x)

f(x) + g(x)

= x² - 2x + 6x + 4

= x² + 4x + 4

Equating to zero

x² + 4x + 4 = 0 ← left side is a perfect square

(x + 2)² = 0, thus

x + 2 = 0 ( subtract 2 from both sides )

x = - 2

Answer:

From the given graph, it is clear that at x = 4, the corresponding y-value of the graph is y = 1

Therefore, we conclude that:

Step-by-step explanation:

Given:

A graph is given

To determine:

g(4) = ?

In other words, from the given graph, we need to determine the value of y at x=4

Finding g(4)

From the given graph, it is clear that at x = 4, the corresponding y-value of the graph is y = 1

Therefore, we conclude that:

Given:

The product of a particular number is 65.

Second value is given by the sum of 8 and the original number.

To find:

The unknown number.

Solution:

Let x be the unknown number.

Then, second number = x+8

The product of a particular number is 65.

[tex]x\times (x+8)=65[/tex]

[tex]x^2+8x=65[/tex]

[tex]x^2+8x-65=0[/tex]

Splitting the middle term, we get

[tex]x^2+13x-5x-65=0[/tex]

[tex]x(x+13)-5(x+13)=0[/tex]

[tex](x-5)(x+13)=0[/tex]

Using zero product property, we get

[tex]x-5=0[/tex] and [tex]x+13=0[/tex]

[tex]x=5[/tex] and [tex]x=-13[/tex]

So, the unknown number is either 5 or -13.

Therefore, the correct option is B.

Answer:

Cassandra 10, Borg 7

Step-by-step explanation:

Let c be Casandra's age and b be Borg's age. We can set the equation c-b=3. We can also set the equation 8c+2b=94. From the first equation we get c=b+3. Substitute this for c to get 8(b+3)+2b=94. Simplify to get 10b+24=94. Subtract then divide to get Borg's age is 7. Then since Cassandra is 3 yrs older than Borg, Cassandra's age is 10

Answer:

9x⁻²  is not a polynomial

Step-by-step explanation:

A polynomial function is a function that involves non-negative integer powers of x such as a quadratic, cubic etc.

A polynomial is a function written in the form of ;

f{x} =aₙxⁿ+aₙ₋₁xⁿ⁻¹+-------+a₂x²+a₁x+a₀

The degree of a polynomial is the highest power of x in the expression

9x⁻² ----in this case, the power is negative thus this is not a polynomial.

Answer:

Not a polynomial

Answer:

188 yards

Step-by-step explanation:

Given

Length of one balloon = 12 feet

Since 1 foot = 1/3 yards

12 feet = x

Cross multiply

1 * x = 1/3 * 12

x = 12/3

x = 4 yards

Hence one balloon will be 4 yards long.

If one balloon = 4 yards long

47 balloons = y

Cross multiply;

1 * y = 4 * 47

y = 188yards

Therefore Cesar will need 188 yards of string for 47 ballooons

Answer:

I THINK is (57°) if it wrong im sorry.

Step-by-step explanation:

5x + 2y = 10

2x + y = 2, 4x + 2y = 4.

Therefore (5x + 2y) - (4x + 2y) = 10 - 4, x = 6.

=> 2(6) + y = 2, y = -10.

The solutions are x = 6 and y = -10.

Given:

The of values of a function.

To find:

The ordered pairs that are found on the graph of the inverse function.

Solution:

If a function is defined as

[tex]f(x)=\{(x,y):x\in R,y\in R\}[/tex]

Then its inverse function is defined as

[tex]f^{-1}(x)=\{(y,x):x\in R,y\in R\}[/tex]

From the given table it is clear that, the ordered pairs of the function f(x) are :

[tex]\{(-2,-14),(-1,10),(0,6),(1,2),(2,-2)\}[/tex]

So, ordered pairs of the inverse function are :

[tex]\{(-14,-2),(10,-1),(6,0),(2,1),(-2,2)\}[/tex]

Therefore, the correct option is B.

The solution to the system is x = -6, y = -30.

An equation contains one or more terms with variables connected by an equal sign.

Example:

2x + 4y = 9 is an equation.

2x = 8 is an equation.

We have,

We can start by substituting the first equation into the second equation, to eliminate y:

2x - y = 18

2x - 5x = 18 (substituting y = 5x)

-3x = 18

x = -6

Now that we know x = -6, we can use the first equation to find y:

y = 5x

y = 5(-6)

y = -30

Therefore,

The solution to the system is x = -6, y = -30.

Answer:

The population will be 39400 in approximately 17 years

Step-by-step explanation:

The increase in population after t years is given by the formula

[tex]P_t = P_0(1+r)^t[/tex]

Here

P_0 is the initial population

r is the growth rate and t is time in years

So far we know,

P_0 = 20000

r = 4%

P_t = 39400

Putting the values in the formula

[tex]39400 = 20000(1+0.04)^t\\39400 =20000(1.04)^t\\\frac{39400}{20000} = (1.04)^t\\1.97 = (1.04)^t[/tex]

Taking natural log on both sides

[tex]ln |(1.04)^t| = ln |1.97|\\t\ ln\ |1.04| = ln\ |1.97|\\t = \frac{ln\ 1.97}{ln\ 1.04}\\t = 17.287\\t \approx 17[/tex]

Hence,

The population will be 39400 in approximately 17 years
