A bread recipe calls for 4 eggs for every pound of flour you use if you had 7 lb of flour how many eggs will you need to make al

Naily [24]

Hello! So I think that
4 eggs = 1 lb
8 eggs=2 lb
12 eggs= 3 lb
16 eggs = 4 lb
20 eggs = 5 lb
24 eggs = 6 lb
28 eggs = 7 lb

So you would need 28 eggs for 7 lb of flour

GuDViN [60]

Answer:

195 m.

Step-by-step explanation:

The time for the sound waves to reach the fish is 0.26/2 = 0.13 seconds.

Distance = speed * time

= 1500 * 0.13

= 195 m.

Several different cheeses are for sale. The cheese comes in wedges

Tpy6a [65]

Answer:

39.30 $cm^{2}$

Step-by-step explanation:

The area of the top surface of the wedge is the same as the area of a sector.

Area of a sector = (θ/ $360^{o}$ ) $\pi$ $r^{2}$

where: θ is the central angle, and r is the radius.

Given that: central angle = $45^{o}$ , radius = 10 centimetre.

Area of the top surface = Area of a sector = (θ/ $360^{o}$ ) $\pi$ $r^{2}$

= $\frac{45^{o} }{360^{o} }$ x $\frac{22}{7}$ x $(10)^{2}$

= $\frac{1}{8}$ x $\frac{22}{7}$ x 100

= 39.2857

= 39.30 $cm^{2}$

The area of the top surface of the wedge is 39.30 $cm^{2}$ .

Find the indicated values, where

Rom4ik [11]

Answer:

option (b) is correct.

The value of $g(f(3)-2f(1))$ is 0.

Step-by-step explanation:

Given: $g(t)=t^2-t$ and $f(x)=1+x$

We have to find the value of $g(f(3)-2f(1))$

Consider the given function $f(x)=1+x$

First evaluate value of function f(x) at x = 3 and 1 then substitute it in $g(f(3)-2f(1))$ .

f(3) = 1 + 3 = 4

f(1) = 1 + 1 = 2

Substitute, we get

$g(f(3)-2f(1))=g(4-2(2))$

Solving further , we get,

$g(f(3)-2f(1))=g(4-4)=g(0)$

Now evaluate $g(t)=t^2-t$ at t = 0 , we get,

$g(0)=0^2-0=0-0=0$

Thus, value of $g(f(3)-2f(1))$ is 0.

Thus, option (b) is correct.

a function f(x) is described by the ordered pair (x,y). if given the function is translated 2 units to the right and then reflec

OleMash [197]

The ordered pairs would be (x-2, -y).

Translating a graph to the right subtracts the number of units from the x-coordinate.

Reflecting across the x-axis negates the y-coordinate.
