Answer:

5 full pieces

Step-by-step explanation:

Given

[tex]Board\ Length = 7\frac{3}{4}ft[/tex]

[tex]Pieces = 1\frac{1}{3}ft[/tex]

Required

Determine the number of pieces that can be cut from the board

This is calculated by dividing the board length by the length of each piece.

[tex]Number = \frac{Board\ Length}{Pieces}[/tex]

[tex]Number = 7\frac{3}{4} / 1\frac{1}{3}[/tex]

Convert to improper fractions

[tex]Number = \frac{31}{4} / \frac{4}{3}[/tex]

Change / to *

[tex]Number = \frac{31}{4} * \frac{3}{4}[/tex]

[tex]Number = \frac{31*3}{4*4}[/tex]

[tex]Number = \frac{93}{16}[/tex]

[tex]Number = 5.8125[/tex]

Round down to discard the decimal parts

[tex]Number = 5[/tex]

Hence, the carpenter can cut full-sized 5 pieces

Answer:

32% = 0.32

50% = 0.50

34% = 0.34

Step-by-step explanation:

0.32 = 32%

Answer:

Total money they had at first $252.

Step-by-step explanation:

Let,

x be the amount Silas had originally

y be the amount Raja had originally

According to given statement;

x = 3y     Eqn 1

x - 84 = y + 42    Eqn 2

Putting x=3y in Eqn 2

3y - 84 = y + 42

3y - y = 42 + 84

2y = 126

Dividing both sides by 2

[tex]\frac{2y}{2}=\frac{126}{2}\\y=63[/tex]

Putting y = 63 in Eqn 1

x = 3(63)

x = 189

Total money they originally had = 189 + 63 = $252

Hence,

Total money they had at first $252.

[tex]10\:\mathrm{units^2}[/tex]

Step-by-step explanation:

The area of a triangle can be given as [tex]\frac{1}{2}\cdot b \cdot h[/tex]. Notice that a base of the triangle is given as 4 units, and the height is marked as 5 units. We know that the segment marked as 5 units is the height of the triangle because it forms a [tex]90^{\circ}[/tex] with the segment marked as 4 units and meets a vertex of the triangle.

Therefore, the area of the triangle is:

[tex]\frac{1}{2}\cdot 4 \cdot 5 = \fbox{$10$}[/tex].

How to solve system of two equations:

First of all, we should get one variable in terms of other variable in one equation and substitute this variable in another equation. And solving that we get two variables value.

If you have two different equations with the same two unknowns in each, you can solve for both unknowns. There are three common methods for solving: addition/subtraction, substitution, and graphing.

Here,

let's consider price of hot dogs = x and price of hamburgers = y

then, 164x + 74y = $706 --- ( 1 )

and 256x + 61y = $884 --- ( 2 )

Now,  from eq - 1 we get x = ($706 - 74y) / 164

Substitute this x value in eq - 2,

256($706 - 74y)/164 + 61y = $884

=> $706*256 - 74y*256 + 61y*164 = $884 * 164

=> 180,736-8940y = 144,976

=> 180,736 - 144,976 = 8940y

=> 35,760/8940 = y

=> y = $4.

By substituting in eq - (1) we get x = $2.5

So, The price of hot dog = $2.5

Step-by-step explanation:

From the question we are told that

Equation of cross section is [tex]y+5= \frac{1}{2x^2}[/tex]

Generally the equation can be rewritten mathematically as

  [tex]y+5= \frac{1}{2}x^2[/tex]

  [tex]x^2=(y+5)2[/tex]

  [tex](x-0)^2=(y-(-5))2[/tex]

Generally the equation of a parabola with vertical axis is mathematically given by

[tex](x - h)2 = 4p(y - k)[/tex]

Therefore  comparing equations

[tex](x-0)^2=(y-(-5))2[/tex]

[tex]4p=2[/tex]

[tex]p=2/4[/tex]

The distance from the bulb to the vertex of the cross section is given by
