Step-by-step explanation:
A loan of £5200 gains interest of £2340 in 5 years.
Find the simple interest rate.
= ? % p.a.
Answer:
We have the formula to get the amount of money after 5 years:
A = Principal x (1 + rate)^year
or
5200 + 2340 = 5200 x (1 + rate)^5
=> (1 + rate)^5 = (5200 + 2340)/5200 = 1.45
=> 1 + rate = 1.077
=> rate = 1.077 - 1 = 0.077 = 7.7%
Hope this helps!

At local florists shop, yellow roses cost $2 and red roses cost $3. Steven wants to spend no more than $25 on a bouquet that includes both yellow and red roses. Let "x" represent the number of yellow roses and let "y" represent the number of red roses.
Answer:
2x + 3y ≤ 25
Completed question;
At local florists shop, yellow roses cost $2 and red roses cost $3. Steven wants to spend no more than $25 on a bouquet that includes both yellow and red roses. Let "x" represent the number of yellow roses and let "y" represent the number of red roses.
Represent the case with an equation.
Step-by-step explanation:
Given;
Cost of yellow roses = $2
Cost of red roses = $3
Maximum cost he can spend = $25
Let "x" represent the number of yellow roses
let "y" represent the number of red roses.
The total cost of yellow roses = 2 × x = 2x
The total cost of red roses = 3×y = 3y
Total = 2x + 3y
The equation for this case can be written as;
2x + 3y ≤ 25

I need help with these questions
1) The length of a rectangular room is five less than double the width, w, of the room. Write an expression to represent the area of the room.
2) A parking area is 8 meters by 10 meters. How much will each side have to increase the area by 88 square meters?
Answer: first problem: 2w-5w
Second problem: one side increases by 4 and another side decreases by -22.
Step-by-step
For the first question: make a rectangle and label the length 2w-5 and the width 5. Next, write w(2w-5). Draw a arrow from w to 2 and another arrow from w to 5. Lastly write 2w^2-5w. Answer: 2w^2-5w
2nd question: make a rectangle. For the length write 10 and for the width write 8 and inside the rectangle write 80. Then draw a arrow and on top of the arrow write +88 and then drew another rectangle and for the length write x+10 and for the width write x+8 and inside the rectangle write 168. Then write this on the bottom of the rectangles;
(x+10) (x+8) =168
X^2+8x+10x+80=168
-168. -168
X^2+18x-88=0
Then make a T-chart and on one of the top column write (x-4) and on the other top column write (x+22)=0
And on the bottom of (x-4) write X=4 and in parenthesis write (increase)
And on the bottom of (x+22)=0 write X=-22 and in parenthesis write (decrease)
Then on the area so of the T-chart write 88 and underline it and write -4+22=18 D. S large +.

Answer:
1ST: MIDDLE 2ND:RIGHT SIDE 3RD: GIRAFFE ON THE LEFTFind the lateral area of the right prism with height 0.3 dm, if the base of the prism is Isosceles trapezoid with bases of 3 cm and 5 cm, and legs of 4 cm;
Answer:
48 cm²
Step-by-step explanation:
The lateral area (L) of a trapezoidal prism is the area of the four rectangles that connect the top and bottom trapezoids.
The four rectangles make one large rectangle with length equal to the sum of the four sides — the perimeter (p).
1. Convert the height to centimetres
[tex]h = \text{0.3 dm} \times \dfrac{\text{10 cm}}{\text{1 dm}} = \text{3 cm}[/tex]
2. Calculate the perimeter
p = 3 cm + 4 cm + 5 cm + 4 cm = 16 cm
3. Calculate the lateral area
L = ph = 16 cm × 3 cm = 48 cm²
The lateral area of the prism is 48 cm².

Every dimension of a triangular pyramid is multiplied by 10 to produce a new figure that is geometrically similar. What effect does this have on
the surface area of the pyramid?
A The surface area of the pyramid is multiplied by 10.
B. The surface area of the pyramid is multiplied by 50.
OC. The surface area of the pyramid is multiplied by 100.
D. The surface area of the pyramid is multiplied by 1,000.
E. The effect on the surface area cannot be determined.
Answer:
The correct option is;
C. The surface area of the pyramid is multiplied by 100
Step-by-step explanation:
The equation for the surface area of a triangular prism is as follows;
A = b×h + 2×l×s + l×b
Where:
b = Base width
h = Height of triangular sides
s = Slant height of pyramid
l = Base Length
Hence where every dimension of the triangular pyramid is multiplied by 10, we have
The surface area of original prism = A₁ = b×h + 2×l×s + l×b
The surface area of the new prism = A₂ = 10·b×10·h + 2×10·l×10·s + 10·l×10·b
A₂ = 100·b×h + 100·2×l×s + 100·l×b = 100×(b×h + 2×l×s + l×b)
Therefore, the surface area of the new pyramid is multiplied by 100.
Answer:
A The surface area of the pyramid is multiplied by 10.
Step-by-step explanation:
A triangular prism is a 3 dimensional shape. A triangular prism has 5 faces: 3 triangles and 3 rectangles.
The total surface area of the triangular prism is calculated as:
(Area of the triangle ÷ 2) + ( Area of the first rectangle) + ( Area of the second rectangle) + ( Area of the second rectangle)
If , every dimension of a triangular pyramid is multiplied by 10 to produce a new figure that is geometrically similar, hence, the surface area of the pyramid is multiplied by 10.

the cone. If the cone has a diameter of 2 3/8 inches and a height of
6 inches, how much ice cream does the waffle cone hold?
Answer:
V=π r^2 h/3
d=2 3/8 inches
convert to radius d=2r
d=2.375 (value of 2 3/8 inches in decimal)
2.375 divide by 2
r=1.1875 inches
V=π r^2 h/3
V=3.14 x 1.1875^2 x 6/3

Points X(6, 8), Y(3, 3), and Z(13, –3) form a triangle. What is the area of △XYZ?
Answer:
34
Step-by-step explanation:
area = bh/2
The area of the triangle with vertices X(6,8), Y(3,3), and Z(13,-3) is 34 square units.
Coordinates of vertices are:
X≡(6,8)
Y≡(3,3)
Z≡(13,-3)
What is the area of a triangle with vertices [tex](x_1,y_1), (x_2,y_2),(x_3,y_3)[/tex]?The area of a triangle with the above vertices is given by:[tex]\frac{1}{2} [x_1(y_2-y_3)+x_2(y_3-y_1)+x_3(y_1-y_2)][/tex]
So the area of the triangle with vertices X(6,8), Y(3,3), and Z(13,-3)
=[tex]\frac{1}{2} [6(3+3)+3(-3-8)+13(8-3)][/tex]
=34 square units.
Hence, the area of the triangle with vertices X(6,8), Y(3,3), and Z(13,-3) is 34 square units.
