Answer 1

Answer:

1. 172 m ²

2. 226.56 m ²

3. 336 cm ²

4. 296 inch ²

5. 461 cm ² wrapping paper

Step-by-step explanation:

1. 32+112+28 = 172 m ²

2. 120+ 72 + 34.56 = 226.56 m ²

(half base 3.6 x 4.8 = 17.28 x 2 = 34.56)

3. Triangle face 48/2 = 24cm x 2 = 48 = 48 +72+96+120 = 336 cm ²

4. 9x3 = 27 3x 10 = 30 9x 10 = 90 90+30+27 = 147 147 x 2 = 296 inch ²

5. Right Angle face Triangular prism

1/2 10.5 x 10 = 1/2 105 = 52,5

x2 = 105cm ²

10.5 x 8 = 120c

x2 = 240 cm ²

8x14.5 = 116cm

105+240+116 = 461 cm²

Find the value for q for the following equation: 15q – 16 = 4(2q + 3)

Answers

Answer:
Q=4
15q-16=8q+12
7q-16=12
7q=28
Q=4

Step 1: Multiply 4 by 2q and 3

Now your equation is 15q - 16 = 8q + 12

Step 2: Subtract 8q from both sides

Now your equation is 7q - 16 = 12

Step 3: Add 16 to both sides

Now the equation is 7q = 28

Step 4: Divid each side by 7

Q= 4

A ball shaped like a sphere has a radius of 1.9 centimeters. Which measurement is closest to the volume of the ball in cubic centimeters?

Answers

Answer:

28.73

Step-by-step explanation:

V=4

3πr3=4

3·π·1.93≈28.73091

Answer:

Step-by-step explanation:

Volume =

4 × π × r³ / 3 <----- This is our volume equation

= 4 × π × 1.9³ / 3 (Substituted the unknown r for the radius given, 1.9 cm)

= 4 × π × 6.859 / 3 (Cubed it, aka: Multiplied 1.9 by itself thrice, 1.9 × 1.9 × 1.9

= 4 × 21.548184011 / 3 (Multiplied 6.859 by pi "π")

= 86.1927360439 / 3 (Multiplied that by 4)

= 28.7309120146 cm³ (Divided it by 3, gave it a ³ dimension because it is 3D, volume.

≈

28.73cm³ or 28.7cm³ or 29cm³. (rounded answers, hundreths, tenths and ones)

How many cubes that measure 2 inches by 2 inches by 2 inches would fit inside a cube that measures 10 inches by 10 inches by 10 inches? Justify.

Answers

25, because a cube that is 10x10 would have an area of 100. and the cubes that are 2x2 would have an area of 4. so you take 100 and divide it by 4. answer is 25.

The number of the small cube that fits inside the larger cube is 125.

Given to us,

Side of small cube, s = 2 inches,

Side of larger Cube. S = 10 inches,

We know that volume of a cube is given by a³, where "a" is the side of the cube.

Volume of the small cube = s³ = 2³ = 8 in.³

Volume of the Larger cube = S³ = 10³ = 1000 in.³

The number of the small cube that fits inside the larger cube

[tex]\bold{=\dfrac{Volume\ of\ the\ Larger\ cube}{Volume\ of\ the\ small\ cube} }[/tex]

[tex]\bold{=\dfrac{1000}{8} = 125 }[/tex]

Hence, the number of the small cube that fits inside the larger cube is 125.

Quadrilateral PQRS was translated 5 units to the right and 3 units up to create quadrilateral P'Q'R'S'. Which rule describes this transformation?
A: (x, y) → (x−5, y−3)
B: (x, y) → (x+5, y+3)
C: (x, y) → (x−3, y−5)
D: (x, y) → (x+3, y+5)

Answers

Answer:

Step-by-step explanation:

As Quadrilateral PQRS was translated 5 units to the right and 3 units up to create quadrilateral P′Q′R′S′.

Therefore, we can conclude that the rule '' A rule for a translation right and up (x + __, y + __) '' describes this transformation.

The transformation which describes the quadrilateral P'Q'R'S' is (x, y) → (x+5, y+3). Therefore, option B is the correct answer.

Given that, quadrilateral PQRS was translated 5 units to the right and 3 units up to create quadrilateral P'Q'R'S'.

What is the translation?

A translation in math moves a shape left or right and/or up or down. The translated shapes look exactly the same size as the original shape, and hence the shapes are congruent to each other. They just have been shifted in one or more directions.

Translation rules:

When the shape is moved towards the right by k units, then replace x with x + k.

When the shape is moved up by k units, then replace y with y + k.

So, translated 5 units to the right

x → x+5

Translated 3 units up

y → y+3

The transformation which describes the quadrilateral P'Q'R'S' is (x, y) → (x+5, y+3). Therefore, option B is the correct answer.
