Answer:
Breadth=45 cm and Area = 3150
Step-by-step explanation:
Length= 70 cm and breadth =?
Perimeter=2(l+b)
or,230=2(70+b)
or,230=140+2b
or,230-140=2b
or,90/2=b
or,b=45cm
Breadth=45cm and Length=70cm
Area=l×b
=70×45
=3150cm^2
Answer: Iron, a solid at room temperature, becomes a liquid at 2800 degrees Fahrenheit (really, REALLY hot) and a gas at 5182 degrees Fahrenheit (about half the temperature of the sun). When things are hot, the molecules and atoms move around more and faster, and when they are cold they are slower.
Step-by-step explanation:
4.) top row: 1, 2, 4, 6, 8, 10
bottom row: 25, 50, 100, 150, 200, 250
5.) top row: 1, 2, 4, 6, 8, 10
bottom row: 50, 100, 200, 300, 400, 500
Y = 20m + 50
The slope, 20 is the amount added each month.
The y-intercept, 50 is the amount that was initially put into the account.
Options a and c
Hello!
As you can see, the opposite side of this angle divided by the hypotenuse is 0.91. To find B, we could multiply by the arcsine using a scientific calculator.
sin
(0.91)≈65.5
Now, we need to convert this into radians. To do so, we multiply by pi divided by 180.
≈1.14
Therefore, angle B will form an arc of about 1.14 radians.
I hope this helps!
