Two kinds of perfume are packaged in square pyramidal bottles. Perfume A is packaged in a bottle with a base of 3 inches square
kondor19780726 [428]

Answer:

The bottle of perfume A contains more glass

Step-by-step explanation:

we know that

The surface area of the square pyramid is equal to the area of the square base plus the area of its four triangular faces

step 1

Find the surface area of Perfume A

SA=3^{2} +4[\frac{1}{2}(3)(2.5)]=24\ in^{2}

step 2

Find the surface area of Perfume B

SA=2.5^{2} +4[\frac{1}{2}(2.5)(3)]=21.25\ in^{2}

step 3

Compare the surface areas

24\ in^{2}>21.25\ in^{2}

therefore

The bottle of perfume A contains more glass

VladimirAG [237]

Answer:

90°-x°=180°[by linear pair]

x=180°-90°

x=90°

angle cbd=45°

45°- (x+5)°=90°

x+5=90-45

x+5=45

x=45-5

NEED HELP!!!
Dahasolnce [82]

Answer:

No.

Step-by-step explanation:

The solution x = 0 means that the value 0 satisfies the equation, so there is a solution. “No solution” means that there is no value, not even 0, which would satisfy the equation.

∆ABC is an isosceles triangle in which angles B and C are congruent.
Brut [27]
Since B and C are congruent, that means that 4x+10=x+34. Using the addition property of equality, I challenge you to solve for x! After you do that, you can note that all the angles in a triangle add up to 180, so 4x+10+x+34+angleA=180. When you find x, you can substitute that in.

If you need help with the addition property of equality for variables, here's an example - 5x+23=4x+3. Subtracting 3 from both sides, we get 5x+20=4x. Next, we can subtract 5x from both sides to get -x=20 and divide both sides by -1 to get x=-20.

Good luck, and feel free to ask with any questions!
