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
-4+8p=9p-12
-4=1p-12
8=1p
p=8
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.
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:
The coordinates you will use are (0, 0) and (-4, 0) because they correspond to points X and Y in Triangle PQR:
Then, simplify everything under the radical:
Finally, take the square root of 16:
= 4
