Solve the equation 1.5y < -6.75

1 answer:

7 0

1.5y < -6.75

First, divide both sides by '1.5'.
$\frac{-6.5}{1.5}$
Second, since 4.5 × 1.5 = 6.5, simplify the fraction to '-4.5'
$y \ \textless \ -4.5$

Answer: y < -4.5

Gary bought 14.8 gallons of gasoline for $33.90. At this rate, how much gas can Gary buy for $5? Round to the nearest hundredth

Anna71 [15]

Answer:

$11.45

Step-by-step explanation:

Find the unit rate by dividing the total money by the total gallons.

33.90 / 14. 8 = 2.29 per 1 gallon.

This means 5 gallons will cost 5*2.29 = 11.45

What is the input of arccos

suter [353]

Answer:

It returns the angle whose cosine is a given number.

Step-by-step explanation:

For every trigonometry function, there is an inverse function that works in reverse. These inverse functions have the same name but with 'arc' in front. (On some calculators the arccos button may be labeled arccos, or sometimes cos-1.) So the inverse of cos is arccos etc. When we see "arccos x", we understand it as "the angle whose cosine is x"

cos30 = 0.866 Means: The cosine of 30 degrees is 0.866

arccos 0.866 = 30 Means: The angle whose cosine is 0.866 is 30 degrees.

Use arccos when you know the cosine of an angle and want to know the actual angle.

Length: 32 in

Answer:

The lateral Area of a cube $= 17.64in^{2}$

Step-by-step explanation:

In Mathematics Geometry, the lateral surface of a solid object like cube would be the face of the sold on its side, excluding base. Meaning, any surface, apart from base, would be included to determine the lateral surface of the solid.

A cube has six sides - also called faces.

A cube has a base i.e. the bottom side of the cube, and an ant-bottom base i.e. the top side of the cube.

So, lateral area of a cube would exclude both bottom side base and anti-bottom side base. In other words, it is the area of all the sides of the object, excluding the area of its base and top.

Hence, lateral area of a cube is the square of all the remaining four sides of the object, excluding the area of its base and top.

Hence, the lateral area of a cube can be calculated by the formula:

Lateral Area of a cube $= 4s^{2}$ , where s is the length of one edge.

So,

As the given length of edge = s = 2.1

So,

lateral Area of a cube $= 4s^{2}$

$= 4(2.1)^{2}$

$= 17.64in^{2}$
