Multiply each by the same constant and you'll get another ratio ie. 5/7 --> 10/14 --> 15/21
Answer:
a)7 cakes=£5.6
b)£2=4 drinks
c)£7.7
Step-by-step explanation:
a)5cakes=£4
1 cake=4/5=£0.8
7 cakes=£5.6
b)1 cake=3/6=£0.5
£2=4 drinks
c)(0.8×4)+(0.5×7)=£7.7
Answer:
∴ ∠BAD = 
(0.2044) = 11.8°
Step-by-step explanation:
i) AD = 9 cm
ii) DC = 3 cm
iii) ∠BCD = 35°
iv) Since AB is parallel to DC and ∠ABD = 90° then we can conclude that ∠BDC = 90°.
v) 
= 0.6128 ∴ BD = 3 
0.6128 = 1.84 cm
vi) ∴ sin(∠ BAD ) = 
⇒ sin(∠ BAD ) = 
= 0.2044
∴ ∠BAD = (0.2044) = 11.8°
The way to do this is by using PEMDAS. P (parentheses) E (exponents) M (multiplication) D (division) A (Addition) S (subtraction). The answer would be -1539
The value of the required integral is 50π where C is the positively oriented circle x2+y2=25
We are given a vector F = -yi + xj. A vector is a quantity with magnitude and direction that is commonly represented by a directed line segment, with length representing magnitude and orientation in space representing direction. We need to use the tangential vector form of Green's Theorem to compute the circulation integral ∫CF⋅dr where C is the positively oriented circle x² + y² = 25
Let the value of the integral be represented by the variable "I".
I = ∫∫[(/x)(x) - (/y)(-y)]dA
I = ∫∫[(1 - (-1)]dA
I = ∫∫2dA
I = 2∫∫dA
I = 2×(Area of the circle)
I = 2*(πr²)
I = 2*(π*25)
I = 50π
Hence, the value of the required integral is 50π.
