Welcome to Brainly, Dolly!

49 factors into 7^2.  7 is prime, and 49 is the square of this prime factor.

56 = 7(8), but 8 itself is the cube of 2.  Thus, 56 = 7*2^3:  7*2*2*2.

42 = 7(6) = 7*2*3

A regular workweek is 40 hours. Overtime pay is time and one-half): Manual is a word-processor operator. He makes $13.50 an hour
pychu [463]
Overtime is over 40 so subtract 40 from 54 and get
54-40=14
14 hours hovertime
so multipliy usuall pay by 40 (since worked 40 normal hours) then add to overtime pay by 14 hours so


(13.5 times 40)+(13.5 times 1.5 times 14)=
540+283.5=823.5
answer is $823.50

1<br> 4<br> Joey enlarged a 3-inch by 5-inch photograph on a copy machine. He enlarged it four times. The table below<br> shows
lozanna [386]

Answer:

3) 5.4

Step-by-step explanation:

Given two points (x1, f(x1)) and (x2, f(x2)), the average rate of change is computed as follows:

[f(x2) - f(x1)]/[x2 - x1]

From the original photograph to the fourth enlargement, the points are (0, 15) and (4, 36.6). Replacing into the equation we get:

[36.6 - 15]/[4 - 0] = 5.4

The point (−3, 1) is on the terminal side of angle θ, in standard position. What are the values of sine, cosine, and tangent of
Ivenika [448]

The length of the hypotenuse = √(-3^2 +1^2) = √10

The point -3,1 tell us the length of y is 1 and the length of x is 3.

This would make opposite = 1 and adjacent = -3

Sinθ = opposite/hypotenuse =  1/√10  = √10/10

Cosθ = adjacent/hypotenuse = -3/√10  = - 3√10/10

Tanθ = opposite/adjacent = 1/-3 = -1/3

Solve the following word problem using any method. Show your work.
VLD [36.1K]
Let's set up two equations:
x+y=20             We know she brought total of 20, some of each so x=small y=big
20x+ 30y=450
 
 x+y= 20
   -y    -y
 ------------
 x= 20 -y

substitute into the other equation:    
20 (20-y) + 30y = 450
400 - 20y + 30y = 450
400+ 10 y = 450
10 y = 50
y= 5

So she brought  5 big cases.  Then substitute the value of y into one of the equations.

5+ x = 20 
x= 15

So we bought 15 small cases and 5 big cases.
