Question 67 and 68 please. Or one or the other.
Umnica [9.8K]

Answer:

question 67-the answer is Rory has eaten 1 1/4 of all the chocolate he has been given.

question 68-answer A-30 degrees

Step-by-step explanation:

question 67:

first Rory ate 1/2 of his chocolate

then, his sister gave him another whole chocolate bar an hour later.

that is 1/2+1=1 1/2--3/2/2=3/4

add 3/4 and 1/2--3/4 1/2~2/4--2/4+3/4=5/4 or 1 1/4

so the answer is 1 1/4

question 68:

if you draw a base to connect the last side of the angle into a triangle, you find that all three sides are equal, making the triangle an equilateral triangle.  An equilateral triangle's angles all equal 30 degrees.

so, the answer is answer A: 30 degrees

Martin is using unit cubes to build a tower in the shape of a rectangular prism. A decripion of the tower is listed the bottom l
leva [86]

Answer:

Volume of the completes tower = 160 units³

Step-by-step explanation:

Martin is using unit cubes to build a tower in the shape of rectangular prism.

Bottom layer of the prism is in the square shape.

Since number of unit cubes used in the bottom layer = 16

So, one side of the square base will measure = √16 = 4 units

Therefore, Length = width = 4 units

On this base, additional layers added on the top = 9

Therefore, height of the tower = (9 + 1) = 10 units (each layer having 16 cubes)

Volume of the tower = Volume of the rectangular prism

                                  = Length × width × height

                                  = 4×4×10

                                  = 160 cubic units.

Volume of the completed tower will be 160 cubic units.

Triangle PQR has coordinates P (0, 0), Q (-4,0), and R (0, 2). If APQR - AXYZ, what is the measure of XY?
SSSSS [86.1K]

Answer:

4 units

Step-by-step explanation:

Since the two triangles are similar, their sides are proportional. To find the length of the side, you need to use the distance formula:

\sqrt{(x_{1} - x_{2})^{2} + (y_{1} - y_{2})^{2} }

The coordinates you will use are (0, 0) and (-4, 0) because they correspond to points X and Y in Triangle PQR:

\sqrt{(0 - (-4))^{2} + (0 - 0)^{2}}

Then, simplify everything under the radical:

\sqrt{16}

Finally, take the square root of 16:

\sqrt{16} = 4
