A pyramid has a square base that has an area of 144 square feet. If the slant height of each triangular face is 10 in, what is the total surface area of the pyramid?
Answers
Answer:
Total Surface Area
= 384 sq ft
Step-by-step explanation:
To find Total Surface Area, add up the areas of all the sides of the shape. A square based pyramid has five sides, a square bottom and four triangular sides. Luckily all four sides are the same, so just one calculation for these.
Area of square base is given.
A = 144 sq ft
Since the base is a square the length of the side of the square is 12, because 12×12 is 144.
The side of the square base is the base of the triangular side.
Area of a triangle:
A = 1/2•b•h
A = 1/2(12)(10)
A = 60
The area of one triangular face is 60. There are four of these.
A = 4(60)
A = 240
This is the area of all the triangular faces.
Add them all up.
A (TOTAL)
= 144+240
= 384 sq ft

Solve the equation by factoring. z2 – 6z – 27 = 0
z = –3 or z = 9
z = –3 or z = –9
z = 3 or z = –9
z = 3 or z = 9
Answers
Answer:
The value of z = -3 or z = 9
Step-by-step explanation:
Given equation => z² – 6z – 27 = 0
=> z² - 9z + 3z - 27 = 0
=> z(z -9 ) +3 (z - 9 ) = 0
=> (z + 3) (z - 9)
=> z = -3 or z = 9
Answer:z = –3 or z = 9

Luke and Ella have money in their bank account in the ratio 7:8
Luke gives £2 to Ella, and the ratio becomes 4:5.
Work out the original amount of money that Ella had.
Answers
Answer:
$48
Step-by-step explanation:
Ratios can be written as fractions.
1) Initially, Luke had 7x money, Ella had 8x money. Luke gives $2 to Ella. So, Luke now has 7x - 2 money and Ella has 8x + 2. The total amount of money is 4:5. These could be shown as fractions.
7x - 2/8x + 2 = 4/5
4(8x + 2) = 5(7x - 2)
32x + 8 = 35x - 10
8 + 10 = 35x - 32x
18 = 3x
18/3 = x
x = 6
2) Substitute the result (x = 6) into 7x:8x.
= 7(6)
= 42
= 8(6)
= 48

Answer:
(a) graph iii)
(b) graph v)
(c) graph ii)
(d) graph iv)
Step-by-step explanation:
All given equations are in vertex form: y = (x - h)² + k
where (h, k) is the vertex of the parabola
The vertex is the turning point of the parabola, so the minimum point for parabolas that open upward, and the maximum point for parabolas that open downward.
Vertices of the given graphs:
i) (-3, 2)
ii) (-3, -2)
iii) (2, 3)
iv) (3, 2)
v) (-2, -3)
vi) (2, -3)
Part (a)
Given equation: y = (x - 2)² + 3
Therefore, the vertex is (2, 3) → graph iii)
Part (b)
Given equation: y = (x + 2)² - 3
Therefore, the vertex is (-2, -3) → graph v)
Part (c)
Given equation: y = (x + 3)² - 2
Therefore, the vertex is (-3, -2) → graph ii)
Part (d)
Given equation: y = (x - 3)² + 2
Therefore, the vertex is (3, 2) → graph iv)
Vertex form of parabola having vertex (h,k)
y=a(x-h)²+k#1
y=a(x-2)²+3Vertex (2,3)

Plant B requires 25. Because B is older and less efficient, production costs are $100 more per motor in B than in A.

A cuboid with a volume of 374cm^3 has dimensions 2cm,(x+3)cm and (x+9)cm
Please help me get the full 7 marks
Answers
Answer:
x² + 12x - 160 = 0
x = 8 or x = -20
The dimensions are 2 cm, 11 cm, 17 cm.
Step-by-step explanation:
The volume of the cuboid is the product of the three dimensions.
volume = 2(x + 3)(x + 9)
volume = 2(x² + 12x + 27)
volume = 2x² + 24x + 54
We are told the volume equals 374 cm³.
2x² + 24x + 54 = 374
2x² + 24x - 320 = 0
x² + 12x - 160 = 0
(x - 8)(x + 20) = 0
x - 8 = 0 or x + 20 = 0
x = 8 or x = -20
We do not use x = -20 because it would cause two dimensions to be negative which cannot be.
x = 8
x + 3 = 8 + 3 = 11
x + 9 = 8 + 9 = 17
The dimensions are 2 cm, 11 cm, 17 cm.
