<h3>Answer:</h3>
<h2><u>27 people</u></h2>
<h3>Explanation:</h3>
If the drama club spent $8.50 per person on food, and if the total cost of food was $229.50. How many people were at the cast party?
To find how many people are there, we need to divide $229.50 to $8.50.
$229.50 ÷ $8.50 = 27
- Thus there are <u>2</u><u>7</u> people at the party.
Answer:
<h2>y = 0 or y = -2/3</h2>
Step-by-step explanation:
The product is zero if one of the factors is equal to zero. Therefore
Answer:
angle BAC = 50.5°
Step-by-step explanation:
To find the size of angle BAC, we will follow the steps below;
First, we will use Pythagoras theorem to find side AC
from the diagram, AB = 14 cm BC = 17 cm
Using Pythagoras theorem,
AC² = AB² + BC²
= 14² + 17²
=196 +289
=485
AC² = 485
Take the square root of both-side
AC = √485
AC = 22 .023
AC = 22.023 cm
angle <B = 90°
Using the sine rule,
=
A = ?
a=BC = 17 cm
B = 90°
b = AC = 22.023 cm
we can now [proceed to insert the values into the formula and then solve for A
=
=
cross - multiply
22.023× sinA = 17× sin90
Divide both-side of the equation by 22.023
sin A = 17 sin90 / 22.023
sin A = 0.771920
Take the sin⁻¹ of both-side of the equation
sin⁻¹sin A = sin⁻¹0.771920
A = sin⁻¹0.771920
A≈ 50.5°
Therefore, angle BAC = 50.5°
Answer:
200 N/m
Step-by-step explanation:
Rearranging the formula F = kx, you find that k = F/x. For the first spring,
F = 36 N and x = 0.06 m (6 cm). So the spring constant, F/x, is 36N/0.06m = 600 N/m
For the second spring, F = 36 N and x = 0.09 m. F/x = 36N/0.09m = 400 N/m
The difference between these values is 200 N/m, and that's the answer.
Answer:
Remember that 6x^2 and -4x are not like terms. I drew a circle around them since those two will come first then goes the 5 and 3. Hopw this helps, thank you !!
