An octagon has an area of 55.3 square inches. It is a smaller version of an octagon whose dimensions are 7 times larger. What is the area of the larger octagon?
9514 1404 393
Answer:
2709.7 square inches
Step-by-step explanation:
If the linear dimensions are a factor of 7 larger, then the area is a factor of 7^2 = 49 larger.
larger area = 49(55.3 in^2) = 2709.7 in^2
3x + 2 = -55 i need all the steps
Answer:
-19
Step-by-step explanation:
3x+2 = -55
-2 -2
3x = -55-2
3x = -55+-2
3x = -57
/3 /3
x=-19
Answer:
-19
Step-by-step explanation:
[tex]3x + 2 = -55[/tex]
[tex]3x = -55[/tex]
[tex]-2[/tex] (2 is negative because it was moved to the other side of the equation)
[tex]3x/3 = -57/3[/tex] (Divide both sides of the equation by 3 to isolate x.)
[tex]x = -19[/tex]
Are my answers correct??
Answer:
Yes, but I'm no expert.
How are convection currents in the mantle (geosphere) and in the oceans (hydrosphere) similar? Or how are they different. Explain one of the two or how their similar and different. Thanks :)
I give brainliest to whichever makes the most sense
Answer:
They are different because in the mantle, the magma is heated, it becomes less dense and rises. It give off it's thermal energy and cools down, becoming more dense and descend to be heated again.
In the ocean, the tropics warm the water and it travels to the poles to cool down, then returns to the tropics to heat up again.
A cylinder has a volume of 24 cubic feet. Which of the following could have the same radius and height as the cylinder?

D. A cone with a volume of 8 cubic feet
what is the value of x
Answer:
x = 105
Step-by-step explanation:
Skills needed: Triangle Angle Measures, Solving a One-Variable Equation
1) To get the answer, you need to know that all the angles inside a triangle add up to 180 degrees. This is very important in the future as well.
2) So to find x, we can make the equation: x + 30 + 45 = 180
3) You can combine like terms:
30 and 45 can be combined --> 30 + 45 = 75
4) Based on step 3, you can get: x + 75 = 180
Subtract 75 from both sides, and you will get: x = 105
Hope this helps and have a nice day! :] :) :D

4/9 kilogram of baking soda costs $2. How much does 1 kilogram of baking soda cost?
please drop an explanation, and equation thanks!
Answer:
1 kg of baking soda costs $4.50.
Step-by-step explanation:
Write and solve an equation of ratios, as follows:
4/9 kg $2
------------- = --------------
1 kg x
Multiplying both numerators by 9, we get:
4 kg $18
------------ = ---------
1 kg x
Cross-multiplying, we get 4x kg = $18-kg. Solving for x, we get:
$18-kg
x = -------------- = $4.50
4kg
1 kg of baking soda costs $4.50.

What is 3x+8 ?
I believe you simplify.
Step-by-step explanation:
Simplifying x = 3x + -8 Reorder the terms: x = -8 + 3x Solving x = -8 + 3x Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-3x' to each side of the equation. x + -3x = -8 + 3x + -3x Combine like terms: x + -3x = -2x -2x = -8 + 3x + -3x Combine like terms: 3x + -3x = 0 -2x = -8 + 0 -2x = -8 Divide each side by '-2'. x = 4 Simplifying x = 4
