balu736 [363]

Answer:

Step-by-step explanation:

First, multiply the bread cost 2.70 by 2, getting you 5.40.

Next, add 11 for the cost of the caketo 5.40 getting you 16.40

Subtract 16.40 from 20 to get how much money you get for the cookies, getting you 3.60

Divide 3.60 by 3 to find how much money each boy gets, getting you 1.20

Divide 1.20 by .40 to get the number of cookies each boy gets, getting you 3

Length: 32 in

Arte-miy333 [17]

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 $= 4s^{2}$

$= 4(2.1)^{2}$

$= 17.64in^{2}$

If X = 14, find the value of the variable a. If your answer is not an integer, express it in simplest radical form.

ivann1987 [24]

Answer:

Step-by-step explanation:

First thing I would do is square the 14, and put it under the radical. Itll make the calculations a little bit easier.

14sqrt(2) = sqrt392

Use the definition of sine to find the value of a

sin(45) = opposite/hypotenuse = a/sqrt392

$sin(45)=\frac{a}{\sqrt{392} }$

a = 14

You've decided to go cave diving. the route between a and b in 8025 meters long and the average diver can swim 15 meters per min

Anastasy [175]

$\text{The route between A and B is 8025 meters.}\\
\\
\text{And an average diver can swim 15 meters per minute.}\\
\text{we need to find the time it will take to complete diving.}\\
\\
\text{by the time distance formula, we know that}\\
\\
\text{Time}=\frac{\text{Distance}}{\text{Speed}}\\
\\
\text{so using this the time taken to complete the dive is}\\
\\
\text{Time}=\frac{8025}{15}\\
\\
\Rightarrow \text{Time}=535 \text{ minutes}$

So the time taken to complete the dive is: 535 minutes
