4*0.79+2*3.99+12.18+3*4.12 =35.68
including tax it's 35.68+ 8%of 35.68=35.68 +(8*35.68/100)=35.68+2.8544=38.5344$
Answer:
1. -40=12x+8 : x=-4
2. -4x+2≥-6x : x≥−1
3. -11≤7x+3 : x≥−2
Step-by-step explanation:
1. Step 1: Flip the equation.
12x+8=−40
Step 2: Subtract 8 from both sides.
12x+8−8=−40−8
12x=−48
Step 3: Divide both sides by 12.
12x
12=−48
12
x=−4
3. Step 1: Flip the equation.
7x+3≥−11
Step 2: Subtract 3 from both sides.
7x+3−3≥−11−3
7x≥−14
Step 3: Divide both sides by 7.
7x
7
≥
−14
7
x≥−2
Answer:
B. 200 mm²
Step-by-step explanation:
The area of a rectangle part of the figure is found using length x width, which in this case is 25 x 2 = 50 mm²
The area of a triangle is found using . Since the values given are the legs that make up the right angle, your base and height are 15 mm and 20 mm. This means the area is , which is 150 mm².
The area of the figure as is whole is 50 + 150, which is 200 mm².
Answer:
2.75 amp
Step-by-step explanation:
Using the formula
Power = Current x Voltage
or
Current,
= Power ÷ Voltage
= 11 watts ÷ 4 volts
= 11/4 amps
= 2.75 amp
