Mathematics
1 answer:
aliya0001 [1]3 years ago
8 0

Step-by-step explanation:

x+3y=12--(1)

x=-6y--(2)

put (2) in (1)

-6y+3y=12

-3y=12

divide both sides by -3

y=(12/-3)

y=-4

put y=-4 in (1)

x+3(-4)=12

x-12=12

x=12+12

x=24

Cheng likes a modern lawn sculpture made of four identical solid right pyramids with square bases. He decides to create an exact
Montano1993 [528]
This is the concept of volumes of solid figures;
To calculate for the volume of material required we calculate for the volume of the pyramid;
volume of the pyramid is given by:
volume=(length*width*height)/3
but in our case the base of the pyramid is square, therefore:
length=width=2 ft
height=6 ft
hence;
volume=(2*2*6)/3
volume=8 ft^3

The answer is 8 ft^3

Triangle XYZ is isosceles. The measure of the vertex angle, Y, is twice the measure of a base angle.
Alik [6]

Answer:

The answer is A, the measure of angle Z is 45°.

Step-by-step explanation: According to base angle theorem for iscoscles triangles, the base angles must be the same angle measure if the sides opposite to them are congruent. Since it is an iscoceles triangle, they are automatically congruent. This means that Y is 90 degrees. This fits into triangle sum theorem because if Z is 45 degrees, than x is also 45 degrees making a viable triangle. This means that this is the only one that actually applies. B is wrong because of triangle sum theorem, C is wrong because of triangle sum theorem, and D is wrong because of the SSS postulate and CPCTC.

Kite WXYZ is graphed on a coordinate plane. What is the area of the kite? 7 square units 8 square units 14 square units 16 squar
Ghella [55]
The area of the kite can be found as follows;
Area=[area of XWY]+[areaYWZ]
area XWY=1/2*b*h
=1/2*4*3=6 sq units

area YWZ=1/2*b*h
=1/2*4*4=8 sq units

Hence the area of the kite will be:
Area=6+8=14 sq. units
