The total amount that Chang will received from his wages is the product of his hourly wage times the number of hours he has worked (n). His total savings should not be less than $125. The equation that best describes the situation is, 
                                    45 + 7n ≥ 125
Solving for n in the inequality gives an answer of n≥11.42 hours. Thus, he needs to work for at least 12 hours.

I) Solve the equation sin2x + 3cos2x = 0 (for 0 till 360°)
galina1969 [7]
Get rid of cos2x by dividing both the values. So Sin2x/cos2x +3cos2x/cos2x.
Tan2x = 3
2x = -71.5 so x is -35.6
Use the quadrant method and add 360 twho the two values tou get.

Julio bought a total of 20 medium and large pumkins if he spent 53$ and bought 6 more large pumkins as medium pumkins how many l
aksik [14]
L = large pumpkin

m = medium pumpkin


Write a system of equations: 

1)   L + m = 20
2)   m = L - 6
3)   $3L + $2m = $53

Substitute L - 6 for m in equation 1:

L + (L - 6) = 20

Add 6 to both sides:

2L = 26
(L + L = 2L)

Divide two on both sides:

L = 13

Julie bought 13 large pumpkins.

Check (use equation 3):

$3(13) + $2(7) = 53
(m = 7 because 20 - 13 = 7)

Multiply:

$39 + $14 = $53       :)

What is the correct order of steps for bisecting angle ABC? Draw a ray from point B through point F. Keeping the compass the sam
Vitek1552 [10]

Answer:

Look to the explanation

Step-by-step explanation:

* Lets arrange the steps for bisecting angle ABC

- The vertex of angle ABC is B, and its rays are BA and BC

# Step 1:

- Place the compass on point B, and swing an arc that intersects rays

 BA and BC ⇒ 5th

# Step 2:

- Place point D on the intersection of the arc on ray BA and point E on

 the intersection of the arc with ray BC ⇒ 3rd

# Step 3:

- Place the compass on point D, and draw an arc inside the angle ⇒ 6th

# Step 4:

- Keeping the compass the same distance, place the compass on

 point E, and draw an arc inside the angle ⇒ 2nd

# Step 5:

- Place point F on the intersection of the arcs created from points D

 and E ⇒ 4th

# Step 6:

- Draw a ray from point B through point F ⇒ 1st

* This ray is the bisector of the angle ABC

A cylinder has a base radius of 6m and a height of 16m. What is its volume in cubic m,
SpyIntel [72]

Answer:

To the nearest tenth place, V = 1,810.3 m^3

Step-by-step explanation:

In this question, we are tasked with calculating the volume of a cylinder given its base radius and height.

Mathematically, the Volume can be calculated using the formula

V = pi * r^2 * h

where pi = 22/7 , r = 6m and h = 16m

Plugging these values, we have

V = 22/7 * 6^2 * 16

V = 22/7 * 36 * 16

V = 1,810.286 m^3

To the nearest tenth place, V = 1,810.3 m^3
