Squares, rectangles and rhombuses are all parallelograms. All parallelograms are squares. Who is correct? Explain why.

Squares, rectangles and rhombuses are all parallelograms, because they have parallel lines. but not all square is parallellograms, example for kite

Identify the centre, radius and diameter of each circle given.

a. centre: R, radius: PR, RS, RQ; diameter: PQ

b. Centre: C, radius: AC, CD, CB; diameter: AB

c. centre: L, radius: JL, LK; diameter: JK

Find the radius and diameter of the following circles.

a. radius: 3 cm, diameter: 6 cm

b. radius: 5 cm, diameter: 10 cm

Find the area of each red triangle. Find the area of the triangles.

1. a. 1/2 x 16 cm2 = 8 cm2. yang b. 1/2 x 25 cm2 = 12,5 cm2

2. a. (4 x 6)/2 = 24/2 = 12 cm2.

b. (7 x 10) / 2 = 70/2 = 35 cm2

Who took more cake? Explain your answer.

Ron --> 36/2 + 40/2 = 18 + 20 = 38 cm2

Izzy --> (8 x 10)/ 2 = 80/2 =40 cm2

What type of angle is described as being less than 90°? What type of angle is described as being greater than 90°? What is the reflex angle? what is the measure angle from picture

3. it is the angle more than 180 degree but less than 360 degree

4. a. 120 degree, b. 235 degree

what is angle of C? What is the angles of Z and Y?

2. 180 - 50 = 130, because its the same line XY and XZ, so the angle is the sama...mean the angle is (180 -50)/2 = 65

5. (90 x 65)/2 = (5850)/2 = 2925 cm2

6. one pattern = one triangle => the area of one pattern = (15 x 10)/2 = 150/2 = 75 cm2

the number of pattern = 13 --> the area whole patterns = 75 x 13 = 975 cm2

d. 180-110 = 70, because the same line the angle is 70/2 = 35 degree

1. triangle 1: 60, 60, 60 degree

2. triangle 2: 101, 19, 60 degree..because total degree is 180 degree

angle x = 180-48-86 = 46 degree, angle Y = 180- 87 - 47 = 46 degree, its the same angle

Emily wants to turn the 3Dshape into a cuboid. what is the number of cubes Emily needs to add to the 3D shape?

total each layer to form cuboid is 12 cubes, so layer 1 needs 4 cubes, layer 2 needs 12-3 = 9 cubes. layer 3 needs 12-1 = 11 cubes

total need cubes are 4 + 9 + 11 = 24 cubes

a. has 6 rectangular faces, so its net has 6 rectangles

b. the triangular prism has 3 rectangular, 2 triangular, so its net has 3 rectangle and 2 triangles

Ralph wants to paint his bedroom. He needs 5 l of paint to paint his bedroom but he only has a 2 l can of paint that is half full. a. What is the capacity of the can of paint? b. What is the volume of paint he has? c. If each can of paint is 2 l, how many more cans of paint does Ralph need to buy?

c. he needs 3 L more, so 3/2 = 1,5 cans

c. (3 x 2 x1) + (2x2x1) + 1 = 6 + 4 + 1 = 11 cubes

a. total for cuboid is = 5 x 2 x 2 = 20 cubes, there are only 10 + 6=16 cuboid, so cube needed are 20-16 = 4 cubes

b. total cuboid = 5 x 2 x 4 = 40 cubes, there are only 10 + 8 + 6 + 4 = 28 cubes, so needed 40 - 28 = 12 cubes

the net has 3 pairs of equal rectangles

its net has 1 square, 4 triangles

What is the volume of the vinegar solution in each measuring cylinder? Which measuring cylinder holds the largest volume of the vinegar solution?

1. A = 20 ml, B = 50 ml, C = 60 ml, D= 40 ml

What is the capacity of the jug? What is the volume of the water in the jug? How much more water is needed to fill 2/5 of the jug?

3. 2/5 capacity is 2/5 x 300 = 120 ml, so water is needed is 120 - 70 = 50 ml

How many 1-cm cubes make up the 3D shape? If the base of the 3D shape is extended to give a cube of side 4 cm. How many more 1-cm cubes are needed to make such a cube? A cubic box has sides of 4cm. Make a conjecture on how many such 3D shapes can fit into the box.

1. Bottom layer: 4 cubes Second layer: 3 cubes Third layer: 2 cubes Top layer: 1 cube, total 10 cubes

2. total cubes become 4 x 4 x 4 = 64 cubes, so we need cube more 64-10 = 54 cubes

3. the volume cubic total is 4 x 4 x 4 cm3 = 64 cm3, each 3D shape is 10 cube, so need --> 64/10 --> at least 6.4 cube or 6 cube

How many cubes of edge 2 cm can fit into the cuboid?

total volume cuboid = 12 x 22 x 8 cm3 = 2112 cm3, volume each cube = 2 x 2 x 2 cm3 = 8 cm3

so cube can fit to cuboid is 2112/8 = 264 cubes

Write an equation for its perimeter. How many combinations of A and B can you find to make A + B = 10 true? If B= 2, what is the value of A?

2. 10+0; 9+1; 8+2; 7+3; 6+4; 5+5; 4+6; 3+7; 2+8; 1+9; 0+10

The letters m and n represent positive whole numbers, m is less than 10. Find all possible values of m and n that satisfy each equation. a. m + n = 5 b. m - n = 7

a. 5+0; 4+1; 3+2; 2+3; 1+4; 0+5

In a month, the average temperature of a particular place in Antarctica was recorded as -39°C. A few months later, the temperature is 23°C lower. Estimate the new temperature.

- 39 is closed to -40, and -23 is closed to -20, so estimate the temperature now is -40 - 20 = -60°C, or excactly -39 - 23 = -62°C

The temperature of a city was recorded as -8°C yesterday. It is 2°C lower today. What is the new temperature? Izzy and Ralph dive into the water from a boat. Izzy is at -8 m and Ralph is at -17 m now. How much further is Ralph under the water surface than Izzy? The deepest point of the sea at two kilometres away from the shore is -172 m. The shallowest point is -1 m. What is the difference between the deepest and shallowest points?

2. -17 - (-8) = -17 + 8 = -9 m, 9 meters further

A scuba diver was at -6 m. He continued diving 4 m every two minutes. Estimate and then calculate how deep he will be after 10 minutes. How do you know?

every 2 minutes for 4 m diving, means for 10 minutes diving to 4 m x 5 = 20 m

so total deep --> -6 m -20m = -26 m.

2.38 +0.525 = 88.65 + 205.4+110.578= estimate 71.9+78.879 =... and then calculate real result.. estimate 68.55 + 50.658 = ... and then calculate real result... estimate 48.611+16.915 = and then calculate real result...

3. estimate 71.9 --> 72, estimate 78.879 --> 79, estimate calculation 72+79=151

the real result 71.9+78.879 = 150,779

4. estimate 68.55 --> 69, estimate 50.658 --> 51, calculate estimation 69+51=120

real calculation 68.55+50.658=119.208

5. estimate 48.611 --> 49, estimate 16.915 --> 17, estimate calculation 49+17=66

real calculation 48.611+16.915 = 65.526

2. the mass heavier object --> 353.481+68.127=421.608

William is coming to celebrate Xavier's birthday. The map shows two different routes to Xavier's house. Which route is shorter?

route 1 --> 3.86 + 8.005 = 11.865

route 2 ---> 5.725 + 7.285 = 13.01

Caz's grandma can take at most 40.49 g of sugar in a week. She has taken in 34.25 g of sugar. What fruit can she eat so that she will not exceed the recommended amount of sugar intake?

40.49 - 34.25 = 6,24 --> a bunch of grapes.

How much heavier is the desktop computer than the laptop computer?

5.715 - 1.524 = 4.191 kg heavier

Estimate: 56.875 - 13.5 =... real calculate 56.875 - 13.5 =... estimate 94.27 - 48.775=.. real calculate 94.27 - 48.775=.. estimate 89.631 - 60.516=.. real calculate 89.631 - 60.516=...

4. real calculate 94,27 - 48,775 = 45, 495

6. real calculate 89.631 - 60.516 = 29,115

What is the distance between the second fret and the fourth fret? Which fret is the second fret closer to, the first fret or the third fret?

1. 95.913 - 32.641 mm = 63.272 mm

2. the distance the third fret to the second fret is 65.390 - 32.641 = 32.749

because the second to the third fret is larger distance, the closer one is the first fret to the second fret is closer
