X, Y and Z are three points on a map. Y is 75km and on a bearing of 200° from X. Z is on a bearing of 150°, from Y. Z is due south of X. Calculate the distance between X and Z rounded to 1 DP.
Answer:
The distance between X and Z is approximately 114.9 km
Step-by-step explanation:
The given parameters are;
The distance of Y from X = 75 km
The bearing of Y from X = 200°
The bearing of Z from Y = 150°
The bearing of Z from X = 180°
In triangle XYZ, we have;
∠YZX = 180° - (130° + 20°) = 30°
By sine rule, we have;
(75 km)/sin(30°) = XZ/(sin(130°))
XZ = sin(130°) × (75 km)/sin(30°) ≈ 114.9 km
The distance between X and Z ≈ 114.9 km. to one decimal place.

A school has 320 girls and 250 boys the probability of a girl being left handed is 0.2 the probability of a boy being left handed is 0.1 estimate the amount of left handed people there are in the school
320 girls & 250 boys
0.2 probability 0.1 probability
320 x 0.2 = 64
250 x 0.1 = 25
64 + 25 = 89
There are approximately 89 students in the school that are left-handed.
Answer
89% of the people are left handed
Step-by-Step Explanation
To find this you have to first do 320 x 0.2
320 x 0.2= 64
To find it for boys you have to do 250 x 0.1.
250 x 0.1= 25
SO, the answer is 89%. 64% of girls and 25% of boys

Sonya had 20 dollars to spend on 3 gifts. She spent 8 1 4 dollars on gift A and 4 4 5 dollars on gift B. How much money did she have left for gift C?
Answer:
6 19/20 dollars
Step-by-step explanation:
Sonya had 20 dollars to spend on 3 gifts.
She spent 8 1 4 dollars on gift A and 4 4 5 dollars on gift B.
Gift A + Gift B + Gift C = $20
Gift C = $20 - (Gift A + Gift B)
Gift A = $8 1/4
Gift B = $4 4/5
Hence:
The amount she had left for gift C is :
Gift C = $20 - ($8 1/4 + $ 4 4/5)
Gift C = $20 - $13 1/20
Gift C = $ 6 19/20

P'(-3, 13), e' (3, 13), R'(-3, 16)
Answer:
We have the answer as:
P'(0, 13), O'(-9, 13), R'(-3, 16)
Step-by-step explanation:
Here, we want to find the coordinates of the image after applying the transformation rule to the pre-image
what the transformation rule is saying is that we subtract 3 from the x-coordinate and add 7 to the y-coordinate
mathematically, we have these as follows;
P’ = (3-3, 6 + 7) = (0,13)
Q’ = (-6-3, 6 + 7) = (-9,13)
R’ ( 0-3, 9 + 7) = (-3, 16)
