Answer:
1A: 29 units²
1B: √29 units
2, 3, 4. see below
5. between 8 and 8.5
Step-by-step explanation:
1A: Split the given square up into 4 triangles and a square in the centre. You'll get 4 triangles of sides 5 and 2, and a centre square of sides 3.
Area = 4(0.5)(5 x 2) + (3²) = 29 units²
1B: Square root your answer in 1A. √29 units
Alternatively you can use Pythagoras' theorem on one of the triangles. √(5² + 2²) = √29 units
2. The area is exactly 17 units, because the area of a square is the length of its side squared. (√17)² = 17, hence the square's area is 17 units.
3. A number that can be expressed as a fraction (includes whole numbers). E.g. 1/2, 1/7, 4
4. A number that cannot be expressed as a fraction. E.g. π, e, √3
5. Consider the closest square numbers to 70. 70 is closer to 64 than 81 (difference of 6 vs 11). Hence √70 should be closer to 8 than 9. Your answer should be between 8 and 8.5.

Answer:
B, C, D, and F are all possible.
Answer:
B, C, D
Step-by-step explanation:
1. A is not possible because right and obtuse both define triangle angles. An angle cannot be obtuse and right at the same time.
2. B is possible because a right triangle can have all sides of different length.
3. C is possible because a scalene triangle can have an obtuse angle.
4. D is possible because an isosceles triangle can have all acute angles.
5. E is not possible because of how equilateral triangles work. When a triangle is equilateral, it is also equiangular, meaning all of its angles are the same. The angles on every type of triangle always add up to 180 degrees. If a triangle is equiangular, the 180 degrees are divided evenly, with every angle being 60 degrees, which is acute. Therefore, an equilateral triangle cannot have a right angle.
6. F is not possible because isosceles and scalene both refer to the side lengths of triangles. A triangle cannot be isosceles and scalene at the same time.
7. G is not possible because equilateral triangles cannot have angles other than 60 degrees and therefore cannot be obtuse.

Find the area of the parallelogram.
Answer:
13.26cm^2
Step-by-step explanation:
A rectangle has a length of 4 millimeters and an area of square 116 millimeters. What is the width? What is the perimeter?
Answer:
Width = 29mmPerimeter = 66mmStep-by-step explanation:
The area of a rectangle can be calculated by the formula:
= Length * Width
As we have the length and the area, we can make the width the subject of the formula to solve for it:
116 = 4 * width
Width = 116/4
= 29 mm
Perimeter is:
= Length + Length + Width + Width
= 4 + 4 + 29 + 29
= 66 mm
What is the area, in square centimeters, of the trapezoid below?
11.7 cm
5.5 cm
6.5 cm
Answer:
50.05 cm^2
Step-by-step explanation:
Ok so first lets find the area of the rectangle before finding the attached triangle. You have to imagine a line separating this shape into a triangle and rectangle.
The rectangle's size is 6.5x5.5=35.75 cm^2
The rectangle's size is 11.7-6.5 to get the base length, which is 5.2
The height is 5.5
So it's 5.2*5.5/2=14.3 cm^2
14.3+35.75=50.05 cm^2

Factor by gcf 6x2+3x+21 The 2 is supposed to be small.
Given:
The expression is:
[tex]6x^2+3x+21[/tex]
To find:
The factor of the given expression by GCF.
Solution:
We have,
[tex]6x^2+3x+21[/tex]
Here, 3 is the greatest common factor (GCF) of [tex]6x^2,3x,21[/tex].
Taking out GCF, we get
[tex]6x^2+3x+21=3(2x^2+x+7)[/tex]
Therefore, the required factor form of the given expression is [tex]3(2x^2+x+7)[/tex].

Step-by-step explanation:
A cylindrical water tank of height 4 m is used to fill containers with dimensions 20 cm X 30 cm X 50 cm. If the tank can fill exactly 200 of these containers, find its base radius. (Take Pi = 3.14)
Answer:
0.35cm
Step-by-step explanation:
Step 1
We find the volume of the container.
The formula = Length × Width × Height
Length = 20cm
Width = 30cm
Height = 50cm
The volume of the tank = 20cm × 30cm × 50cm
= 30000 cm³
Step 2
We are told that:
The tank can fill exactly 200 of these containers
We have to find the volume that 1 cylinder will contain
Hence,
200 containers = 30000 cm³
1 container = x
Cross Multiply
200 × x = 30000cm³
x = 30000cm³/200
x = 150cm³
Step 3
We find the base radius of the cylindrical tank
Height = 4m
Convert to cm
1m = 100cm
4m = x
Cross Multiply
x = 4 × 100cm = 400cm
Volume of the cylinder = πr²h
Radius = √V/πh
Radius = √150/π × 400
Radius = 0.35 cm
Therefore, base radius = 0.35cm

Solve for x, it’s confusing me because of how it’s split
Answer:
x=30m
Step-by-step explanation:
Smaller triangle of sizes 26m and 10m...
using Pythagoras rule...let the middle line that so the triangle be y...
26² = 10²+y²
26²-10²=y²
y²=676-100
y²=576
y=√576
y=24m
the middle line is now 24m
now the larger triangle of sizes 18m, 24m and x...
using Pythagoras rule...
x²=24²+18²
x²=576+324
x²=900
x=√900
x=30m
circle c shown below was dilated with the origin as the center of dilation to create circle C' which rule represents the transformation?
Answer:
A. (x, y) → (2/7x, 2/7y)Step-by-step explanation:
Equation of the smaller circle:
x² + y² = 2²Equation of the greater circle:
x² + y² = 7²The scale factor is the ratio of radiuses:
k = r₁ / r₂ = 2/7So the rule is:
(x, y) → (kx, ky) = (2/7x, 2/7y)Correct choice is A
Answer:
[tex]\sf A. \quad (x, y) \rightarrow \left(\dfrac{7}{2}x, \dfrac{7}{2}y \right)[/tex]
Step-by-step explanation:
The distance from the center of the circle to any point on the circumference is the radius.
From inspection of the given graph:
Radius of Circle C (before dilation) = 2 unitsRadius of Circle C' (after dilation) = 7 unitsTo find the scale factor of the dilation from the small circle C to the large circle C', divide the radius of the large circle by the radius of the small circle.
Therefore, the dilation is an enlargement of scale factor ⁷/₂ about the origin.
So the rule that represents the transformation is:
[tex]\sf (x, y) \rightarrow \left(\dfrac{7}{2}x, \dfrac{7}{2}y \right)[/tex]
Check (see attached):
Point (0, 2) is on circle C.
[tex]\implies \sf (0, 2) \rightarrow \left(\dfrac{7}{2}(0), \dfrac{7}{2}(2) \right)=(0,7)[/tex]
Point (1, √3) is on Circle C:
[tex]\implies \sf (1, \sqrt{3}) \rightarrow \left(\dfrac{7}{2}(1), \dfrac{7}{2}(\sqrt{3}) \right)=\left(3.5,6.06)[/tex]

Complete the square to write each equation in vertex form. Then, state whether the vertex is a minimum or a maximum and give its coordinates.
Answer:
see explanation
Step-by-step explanation:
The equation of a parabola in vertex form is
y = a(x - h)² + k
where (h, k) are the coordinates of the vertex and a is a multiplier
• If a > 0 then vertex is minimum
• If a < 0 then vertex is maximum
Given
y = x² + 6x + 10
(a)
To complete the square
add/subtract ( half the coefficient of the x- term)² to x² + 6x
y = x² + 2(3)x + 9 - 9 + 10
y = (x + 3)² + 1 ← in vertex form
(b)
Since a = 1 > 0 then vertex is a minimum
(c)
(h, k ) = (- 3, 1 ) ← coordinates of vertex
