Answer:
Step-by-step explanation:
Given:
In Δ ABC
m∠C= 90°
For the triangle ABC we can apply trigonometric ratio to find m∠A.
We have:
Substituting values of side BC and AC
Taking inverse tan to get m∠A.
∴
AB can be found out using Pythagorean theorem:
AB being the hypotenuse can be written as
Substituting values of side BC and AC
Taking square roots both sides:
∴
Answer:
for 0.5 pounds size, we have 7.5
for 0.25 pounds size, we have 15
Step-by-step explanation:
Here, we want to calculate the number of each hamburger size that could be made
for 0.5 pounds size, we have that;
3.75/0.5 = 7.5
for 0.25 pounds, we have;
3.75/0.25 = 15
Answer:
3.
Step-by-step explanation:
If its an AS it well have a common difference, so 3rd term - 2nd term should = 2nd term - first term:-
29 + x - (28 - x) = 28 - x - (15 + x)
2x + 1 = 13 - 2x
4x = 12
x = 3.
The sequence is
15 + 3, 28-3, 29 + 3
= 18, 25, 32
which is arithmetic with common difference 7.
Answer:
Multiply the numbers in parentheses by 3.
Which gives you 12 + 6b - b =27
Combine like terms
12 + 5b = 27
Then subtract 12 from both sides
Which leaves you with
5b = 15
Divide both side by 5
which gives you
answer C
