A possible problem for the multiplication 4 x 2/3 is In a tourist lake there are 4 boats to go on the lake each with 3 seats. Sunday, all boats are busy but only with 2 passengers.

A mathematical problem is a series of data related to a scenario or event that poses a problem in which we must use mathematical operations and procedures to solve it.

According to the above, an example of a mathematical problem is the situation in which the 4 boats on a tourist lake are occupied but only 2 of the 3 chairs available on each boat are being used.

Answer:

Approximate difference between 1 mile and 2 km in meters = 390.66meters

Step-by-step explanation:

I mile =1609.34meters

also 1000m = 1km

therefore 2km = 2 x 1000= 2000m

Approximate difference = 2000m - 1609.34m

=390.66 meters.

 Approximate difference between 1 mile and 2 km in meters = 390.66meters

Step-by-step explanation:

Answer:

The Area of the given figure is 6 inch²

Step-by-step explanation:

For a given Trapezoid

side a = 1 ½ = 1.5 inch

side b = 2½ = 2.5 inch

height (h) = 3 inch

Now, Area of Trapezoid

A = ½ (a + b) × h

A = ½ (1.5 + 2.5) × 3 inch

A = ½ × 4 × 3 inch

A = 2 × 3 inch

A = 6 inch²

Thus, The Area of the given figure is 6 inch²

Answer:

  38 yards

Step-by-step explanation:

Let x represent the length and y the width, both in yards. Then the required relations are ...

  2(x+y) > 132 . . . . . . the perimeter is greater than 132 yards

  y = x - 8 . . . . . . . . . . width is 8 less than length

Substituting for y in the first equation gives ...

  2(x +(x -8)) > 132

  4x -16 > 132

  x -4 > 33

  x > 37

The smallest length the fence can be is 38 yards.

__

Check

At that length, the width is 30 yards, and the perimeter is 2(38+30) = 136 yards. If the length were 37 yards, the perimeter would be 132 yards, which is not greater than 132 yards.

Answer:

C

because it has all the possible inputs for the function

Answer:

The sequence is Arithmetic because it uses subtraction.

The first term is a(1) = 65 since it comes first in the formula.

Step-by-step explanation:

We are given the equation 65-100n. 65 is the first term since it comes first in the arithmetic formula and 100n is the common difference. So the correct answer should be an arithmetic sequence and 65 as the first term.

Answer:

Height of Tower = 41.8901 ft

Base to Ground Wire = 94.0905 ft

Step-by-step explanation:

So you want to find the opposing side of the angle, as well as the distance from the base to where the wire is attached to the ground. You would need to use CAH to find the ground, and SOH to find the height. To find the height or opposite, take the Sine of 24°, 0.4067, and times it by your hypoteneuse 103 to get an exact height of 41.8901 ft. Next, use the Cosine of 24°, 0.9135, and times that by your hypoteneuse 103 to get 94.0905 ft.

Here are the equations:

sin(24)=[tex]\frac{h}{103}[/tex]

cos(24)=[tex]\frac{h}{103}[/tex]

The base of the utility tower from the location where wire is attached to the ground is 94.09 feet and the wire attached to the tower at a height of 41.89 feet.

In a right angle triangle ratio of adjacent side to the hypotenuse side is equal the cosine angle between them.

[tex]\cos\theta=\dfrac{a}{c}[/tex]

Here, (a) is the adjacent side, (c) is the hypotenuse side and [tex]\theta[/tex] is the angle made between them.

The length of the wire is 103 foot. This is the hypotenuse side of triangle made by the wire, tower, and ground.

The angle between the wire (hypotenuse side) and ground (adjacent side) is 24 degrees. Therefore, the cosine angle can be given as,

[tex]\cos (24^o)=\dfrac{a}{103}\\0.9135\times103=a\\a=94.09\rm ft[/tex]

In a right angle triangle ratio of opposite side to the hypotenuse side is equal the sine angle between them. Let the height of the tower (opposite side) is b ft. Therefore,

[tex]\sin(24^o)=\dfrac{b}{103}\\0.4067\times103=b\\b=41.89\rm ft[/tex]

Thus, the value from the base of the utility tower from the location where wire is attached to the ground is 94.09 feet and the wire attached to the tower at a height of 41.89 feet.
