Answer:
$67.50
Step-by-step explanation:
Multiplying $100 by 0.75 results in $75. This price reflects the 25% off discount.
Multiplying this $75 by 0.90 results in $67.50. This price reflects both the initial 25% discount and the additional 10% discount.
Answer:
Option D.
Step-by-step explanation:
we know that
The area of a trapezoid is equal to
we have
substitute the values
I'm pretty sure the simplified answer of (4x^3y^-5)^4 would be 256x^12/y^20 (this is a fraction)
Hope this helps :)
Answer: For 3 Batches, 6 butter & 9 flour
For 5 Batches, 10 butter & 15 flour
Step-by-step explanation:
1 Batch = 2:3
So, whatever we times up by in batches we can do the same to the ingredients.
1 batch = 2:3
multiply 3
3 batches = 6:9
and so on…
Answer:
17.32m ; 110°
Step-by-step explanation:
Distance between X and Z
To calculate the distance between X and Z
y^2 = x^2 + z^2 - (2xz)*cosY
x = 20, Z = 10
y^2 = 20^2 + 10^2 - (2*20*10)* cos60°
y^2 = 400 + 100 - (400)* 0.5
y^2 = 500 - 200
y^2 = 300
y = sqrt(300)
y = 17.32m
Bearing of Z from X:
Using cosine rule :
Cos X = (y^2 + z^2 - x^2) / 2yz
Cos X = (300 + 100 - 400) / (2 * 20 '*10)
Cos X = 0 / 400
Cos X = 0
X = cos^-1 (0)
X = 90°
Bearing of Z from X
= 20° + X
= 20° + 90°
= 110°
