Answer:
second box is 5 and third bo is 40 and forth box is 0.25 I think! Sorry if it’s wrong!
Step-by-step explanation:
you divide them all by four.
B.8 adults
because $5.50*8=$44 $98-$44=$54 54/4.5=12kids
-7x + 4y = -6
2x - 5y= 21
<u>Make it so x's are equal</u>
-14x + 8y = -12
-14x - 40y = 147
<u>Subtract</u>
-32y = -169
<u>Divide</u>
y = 5.28125
<u>Plug in the y value</u>
2x - 5(5.28125) = 21
<u>Simplify</u>
2x -26.40625 = 21
<u>Add</u>
2x = 47.40625
<u>Divide</u>
x = 23.703125
Hope this helps! ;)
We know CXD form a 90 degree angle, plus 32 that is angle BXC
90+32=122
We also know XH bisects this angle, which means it cut it in half,
122/2= 61
Answer: 61
Answer:
The volume of a 3D figure can be determined by the sum of all the cross-sections of that 3D figure parallel to the base
Step-by-step explanation:
<u>We need to understand what a cross-section of a 3D figure ? </u>
A cross section is the shape we get when cutting straight through an object
and in geometry it is the shape made when a solid is cut through by a plane.
=> the cross section is parallel to the base of the figure.
So that the area of the cross-section is determined by its shape
Hence, The volume of a 3D figure can be determined by the sum of all the cross-sections of that 3D figure parallel to the base
