Answer:

1.8181818181818181 etc., which rounds to 1.82

Step-by-step explanation:

1.65/3 = 1/x

3/1.65

We get 1.80 pounds of flour for 1 dollar.

Unitary method is a mathematical technique for first deriving the value of a single unit then deriving any given unit from it.

Suppose we know one mango costs 4 dollars so 20 mangoes will cost (4×20) dollars = 80 dollars.

According to the given question three pounds of flour cost 1.65 dollars.

So, One pound of flour will cost (1.65/3) dollars which is

= 0.55 dollars.

In 1 dollar we will get (1/0.55) pounds of flour which is

= 1.81 pounds.

Rounding 1.81 to nearest hundredth will be 1.80 as the rightmost digits is than 5.

Answer:

the answer is $120

Step-by-step explanation:

because I multiply 15 x 8 = 120 so the hourly worker will have $120 from an eight hour shift or else you can use a calculator too

The required wage for the eight-hour shift is $120.

An hourly worker whose wage is $15 per hour will be paid. How much for an eight-hour shift to be determined.

In mathematics, it deals with numbers of operations according to the statements.

Here,
$15 wage =  1 hour
Multiply both sides by 8
$15*8 = 1*8 hour
$120 = 8 hour

Thus, the required wage for the eight-hour shift is $120.

The triangle on the right is bigger than the triangle on the left.

I am joyous to assist you at any time.

Answer:

6√24 or 29.39metres

Step-by-step explanation:

Area of a triangle is bh/2

The perimeter of an equilateral triangle is 3b

This equilateral triangle can be imagined as two adjoining 30-60-90 triangles. Together, their area is the given 24√3 m²

The base of the individual triangle is √24. The height is √24√3. Multiplying those factors, we get the given area, a proof of sorts, but mure importantly, we can calculate the length of the hypotenuse as 2√24.

sin(30°) = 0.5

√24/(0.5) = 2√24

That is the length of the side of the original equilateral triangle.

The perimeter is 3 times the length of the side:

(3)(2√24) = P

6√24 meters is the perimeter.

Answer:

41.4 im pretty sure

Step-by-step explanation:

Answer:

c = 20

Step-by-step explanation:

Given that,

A rectangle PQRS,

QT = c and ST = 4c-60

We need to find the value of c.

We know that the diagonals of a rectangle bisect each other such that,

QT = ST

Putting values,

c = 4c - 60

Taking like terms together,

60 = 4c - c

60 = 3c

c = 20

Hence, the value of c is 20.

Answer:

y > 1/3 x -3

Step-by-step explanation:

slope = 1/3

y intercept = -3

(a) For some given x, A(x) gives the signed area under f(t) on the interval [a, x]. Since f(t) is simple to integrate, and with a = 2, you can compute it exactly:

A(x) = ∫₂ˣ f(t) dt

A(x) = ∫₂ˣ (3t + 2) dt

A(x) = (3/2 t ² + 2t ) |₂ˣ

A(x) = 3/2 x ² + 2x - 10

which is parabolic and easy to graph.

(b) Differentiating A(x) is also easy if you use the "closed" form above:

A'(x) = (3/2 x ² + 2x - 10)'

A'(x) = 3x + 2

and this function tells you how the area under f(t) changes as you adjust the size of the integration interval.

You can get the same result using the fundamental theorem of calculus:

A'(x) = d/dx ∫₂ˣ f(t) dt = f(x) = 3x + 2

The difference between SALT I and SALT II is SALT I limited weapons, while SALT II limited launchers. So, correct option is A.

The Strategic Arms Limitation Talks (SALT) were a series of negotiations between the United States and the Soviet Union to limit and reduce the number of nuclear weapons and delivery systems.

SALT I was signed in 1972 and focused on limiting the number of ballistic missiles and bombers each side could possess. It also established a system for verifying compliance with the treaty.

SALT II was signed in 1979 but was never ratified by the U.S. Senate due to increased tensions between the two countries. SALT II aimed to further reduce the number of strategic nuclear weapons and delivery systems, but unlike SALT I, it focused on limiting the number of launchers rather than weapons themselves.

Therefore, the correct answer is A.
