Mathematics

erastova [34]3 years ago
5 0

Answer:

The height of the pyramid is 2.4\ ft

Step-by-step explanation:

we know that

The volume of a square pyramid is equal to

V=\frac{1}{3}b^{2}h

we have

V=20\ ft^{3}

b=5\ ft

substitute and solve for h

20=\frac{1}{3}(5)^{2}h

60=(25)h

h=60/(25)=2.4\ ft

The perimeter of this square is 20 inches.
Rashid [163]

Answer:

Amaya is wrong.

Step-by-step explanation:

The perimeter of the square is 20 inches, which means each side of the square needs to add up to 20 inches. If the side length of that side Amaya pointed out is 4 inches, then the total perimeter would only be 18 inches, in another case, if they were talking about the area of the square/rectangle (now), it would be 20 inches. So, Amaya is wrong.

a_sh-v [17]

Answer: 40

Step-by-step explanation:

Given

Jar contains 200 old dimes

Chances to pick the 1960s is 20% i.e. 1960s is 20% of 200 old dimes

So, we can write

\Rightarrow \text{No of 1960s is }=20\%\ \text{of}\ 200=0.2\times 200\\\Rightarrow \text{No of 1960s is }=40

-2x-2+x^2+x+180+-2x-2=180
Dominik [7]

Answer:

x= 4, -1

Step-by-step explanation:

-2x - 2 + x^2 + x + 180 - 2x - 2 = 180

add like terms and put in descending order

x^2 - 3x + 176 = 180

subtract 180 from both sides

x^2 - 3x - 4 = 0

factor out the equation

(x-4)(x+1)=0

solve for x

x-4=0        x+1=0

x=4            x=-1
