Answer:

A. 30 inches

B. 11 pieces

Step-by-step explanation:

Piece 1 = 120 inches

Piece 2 = 210 inches

1. He wants the smallest pieces to be as long as possible without having any leftover, how long should each piece be?

Find the highest common factor of 120 and 210

120: 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 24, 30, 40, 60, and 120.

210: 1, 2, 3, 5, 6, 7, 10, 14, 15, 21, 30, 35, 42, 70, 105, 210.

The highest common factor of 120 and 210 = 30

Therefore, the smallest and longest pieces should be cut into 30 inches each

B. Total Smaller pieces of wood = piece 1 / 30 + piece 2 / 30

= 120/30 + 210/30

= 4 + 7

= 11 pieces

Answer:

-2y=-5x=3

Step-by-step explanation:

Make sure every variable is on one side of the equation and you get the answer.

Answer:

y= -2/5x - 6

Step-by-step explanation:

Use Rise/Run with any of the given points! You go up two, left 5. That proves the slope is -2/5. The line hits the Y axis at -6, so the y-intercept is -6!

Answer:

Hello the answer is

diameter = 49cm;

radius = diameter/2 = 24.5cm;

circumference = 2πr ≈ 153.94 = 154cm

Answer:

the first cell next to 3 (time hours x) is 300

the  point is (3, 300)

the second cell is 1000

the point is (10,1000)

the values for the second table should be the same if they have the same unit rate which is 100 watts per hour

Step-by-step explanation:

If there is 100 watts perhour just multiply the  number of hours by this unit

Answer:

4x^2+17x+15

Step-by-step explanation:

(4x-3)(x+5)

= 4x(x+5) -3(x+5)

= 4x^2+ 20x -3x + 15

= 4x^2 + 17x + 15

Answer:

200+200+1,000+6,000 = 7,400 - 1,200 = 6,200

6,000+200=6,200

Step-by-step explanation:

so 200 plus 200 equal to 400 plus 1,000 equal to 1,400 plus 6,000 equal to 7,400 and then 7,400 subtract by 1,200 equal to 6,200.

and 6,000 plus 200 equal to 6,200.

Hope this helps! :)

Answer is 6,200

Answer:

x=0

x=1

The table already give us a hint, which is a set of values that are telling us what is the value of every function f(x) and g(x) for a given value for 'x' variable.

From the table we know that f(x) decreases when x>0 and goes in the other direction when x<0.

g(x) goes on a different direction, when x>0, it gets bigger, and when x<0, the function decreases.

So the two functions do not have too much space for being equal.

So, you can use the points given in the table to start your test.

f(0)= 0,25 ^ 0=1 since a number raised to 0 is always 0.

g(0)=-0.75 * 0 + 1 = 1

f(1)=0.25^1=0.25 since a number raised to 1 is always equals to itself

g(1)=-0.75*1+1=0.25

So f(x)=g(x), when x=1 and when x=0

Answer:

  y = 2x + 8

Step-by-step explanation:

You can see that the line crosses the y-intercept at 8 which is point (0, 8). From that y-intercept point you rise 2 then run 1 to get to point (2, 12), this rise over run is your slope 2/1 or simply 2.

y = mx + b

m is your slope

b is your y-intercept

y = 2x + 8

Answer:

$22.50

Step-by-step explanation:

8 slices = $12

8/4 = 2

$12/4 = $3

8 + 6 = 14

14 s = $21

1 slice = $1.50

* 15 = $22.50

Answer:

length of box = 56cm

breadth = 0.4m = 40cm

height = o.25m = 25cm

Volume of Box = Volume of soap × n

n = number of soaps.

LBH = lbh × n

56 × 40 × 25 = 7 × 5 × 2.5 × n

n = 56×40×25/35×2.5

n = 56000/87.5

n = 640

so, 640 soaps can be placed in the box.

The value of 'r' in the expression 24(34 + r) = 1200 is 16.

There are three types of basic arithmetic laws of operation.

Commutative law for addition and multiplication states,

a + b = b + a.

a×b = b×a.

Distributive law states,

a(b ± c) = ab ± ac.

Associative law states,

a + (b + c) = (a + b) + c.

Given, An expression 24(34 + r) = 1200.

First, we'll distribute LHS,

24×34 + 24×r = 1200.

816 + 24r = 1200.

24r = 1200 - 816.

24r = 384.

r = 384/24.

r = 16.

Answer:

4/7 > x > -11/7

Step-by-step explanation:

First, add -4/3 to all parts

then divide all parts by -7/3

so, We need to separate it into two inequalities

[tex] \frac{4 - 7x}{3} > 0[/tex]

[tex] \frac{4 - 7x}{3} < 5[/tex]

then we solve for x,

[tex] \frac{4 - 7x}{3} > 0 = x < \frac{4}{7} [/tex]

[tex] \frac{4 - 7x}{3} < 5 = x > - \frac{11}{7} [/tex]

so we ended up like this

[tex]x = ( - \frac{11}{7} \frac{4}{7})[/tex]
