Answer:

$0.65 per pound

Step-by-step explanation:

Divide the total cost by the number of pounds to find price per pound.

$2.60 ÷ 4 = $0.65 per pound

Answer:

That number is  9.77 x 10²² .

Step-by-step explanation:

Answer:

9.777 x 10^22

Step-by-step explanation:

in order to put a number in scientific notation, you have to move the invisible decimal over to the right since the number is a large number. in this case, the invisible decimal would start between 9 and 7. if you put this decimal to the right until you reach the last zero of the right, you would have move the decimal 22 spaces to the right

Given:

The system of equations is

[tex]y=-6x+10[/tex]

[tex]y=-6x+3[/tex]

To find:

The solution of given system of equations.

Solution:

Slope intercept form of a line is

[tex]y=mx+b[/tex]

where, m is slope and b is y-intercept.

For [tex]y=-6x+10[/tex], slope is -6 and y-intercept is 10.

For [tex]y=-6x+3[/tex], slope is -6 and y-intercept is 3.

Slopes of both lines are but the y-intercepts are difference. So, the two lines are parallel.

Therefore, the given system of equation has no solution.

Answer:

they ate 3/4 part of pizza

Step-by-step explanation:

=1/2+1/4

=1×2/2×2 + 1/4

=2/4+1/4

=3/4

Answer:

B) 1/4 because if the pizzas have 8 slices then 1/4=2 slices and 1/2=4 slices    4-2=2 and 2 slices equal 1/4 of the pizza.

Answer:

2x + 5y = 36 in standard form

Step-by-step explanation:

m = [tex]\frac{y_{2} -y_{1} }{x_{2} -x_{1} }[/tex]

y - [tex]y_{1}[/tex] = m( x - [tex]x_{1}[/tex] )

~~~~~

(3, 6)

(8, 4)

m = [tex]-\frac{2}{5}[/tex]

y - 6 = [tex]-\frac{2}{5}[/tex] ( x - 3 )

y = [tex]-\frac{2}{5}[/tex] x + [tex]\frac{36}{5}[/tex] in slope-intercept form

2x + 5y = 36 in standard form

Step-by-step explanation:

right on edge 2022

Step-by-step explanation:

So we know that for 12 rock cakes we need 225g flour and 75g sugar to get 42 rock cakes we need to multiply the number of ingredients by 3.5 (42/12 =3.5)

This gets us 787.5 g flour and 262.5 g sugar.

Show work:

[tex]42 \div 12 = 3.5[/tex]

[tex]225 \times 3.5 = 787.5[/tex]

[tex]75 \times 3.5 = 262.5 [/tex]

[tex]787.5 < 800[/tex]

[tex]262.5 < 300[/tex]

Nishat has enough flour and sugar to make 42 rock cakes.

Answer:

x=-144

Step-by-step explanation:

[tex]\frac{x}{6} +12=-12[/tex] subtract 12 on both sides

[tex]\frac{x}{6}=-24[/tex] multiply by six

x=-144

Answer:

6.45 feet

Step-by-step explanation:

He starts 17 and 1/2 feet off the ground

Elevation relative to ground: 17 1/2

Then he increases the height by 4 and 3/4

Expression: 17 1/2 +4 3/4

Elevation relative to ground: 22 1/4

Next he decreases the elevation by 15.8 feet

Expression: 22.25-15.8

Elevation relative to ground: 6.45

The answer 6.45 feet from the ground

Answer:

21

Step-by-step explanation:

Answer:

120

Step-by-step explanation:

Divide 2400 by 20 to get your answer! It may be wrong

Answer:

W = 40

L = 60

Step-by-step explanation:

L = 20 + W

L*W = 2400

(20 + W)*W = 2400

W^2 + 20*W - 2400 = 0

(W + 60)*(W - 40) = 0

W = 40 (yards)

L = 20 + W

= 20 + 40 = 60

W = 40

36. -3, 2

37. -6, -5

38. 8, -9

39. 7, 0

Step-by-step explanation:

31. -12 + -2 = ‐14 and -12 x -2 = 24

32. 6 + -3 = 3 and 6 x -3 = -18

33. -4 + 4 = 0 and -4 × 4 = -16

34. 8 + 1 = 9 and 8 x 1 =8

35. -6 + 2 = -4 and -6 x 2 = -12

36. -3 + 2 = -1 and -3 x 2 = -6

37. -6 + -5 = -11 and -6 x -5 = 30

38. 8 + -9 = -1 and 8 x -9 = -72

39. 7 + 0 = 7 and 7 x 0 = 0

Answer:

I think it is 7.86.

Step-by-step explanation:

You should change 8 1/3% to a decimal that equals 8.33333333333. I then had took 64/8.33333333333 which equaled 7.86.

Answer:

t = 15 s

Step-by-step explanation:

A projectile is thrown upward so that it's distance above the ground after t seconds is as follows :

[tex]h=-16t^2+480t[/tex] ...(1)

We need to find after how many seconds does it reach its maximum height. For maximum height, put [tex]\dfrac{dh}{dt}=0[/tex]

[tex]\dfrac{d(-16t^2+480t)}{dt}=0\\\\-32t+480=0\\\\t=\dfrac{480}{32}\\\\t=15\ s[/tex]

So, it will reach its maximum height in 15 seconds.

Answer:

B. A = 1, B = 0, C = 8

Step-by-step explanation:

The equation of a vertical line is

x = c

where c is the value of the x- coordinates the line passes through.

The line passes through (8, 6) with x- coordinate 8, thus

x = 8 is the equation of the vertical line

In comparison to

Ax + By = C, then

A = 1, B = 0, C = 8, that is

x + 0 = 8

x = 8 being the required equation
