Given:
right triangle
a = 2.9
c = 4.2
Pythagorean Theorem: a² + b² = c²
missing value of b.
b² = c² - a²
b² = (4.2)² - (2.9)²
b² = 17.64 - 8.41
b² = 9.23
b = √9.23
b = 3.03 or 3.0
The value of b is 3.0
8x + y = -16 ;
3x - y = 5 ;
____________(+)
11x = -11;
x = - 11 / 11 ;
x = - 1;
y = -5 + 3 * ( - 1 ) = - 8.
Answer:
50yds²
Step-by-step explanation:
area of a triangle equals base times height divided by 2
a=20*5/2
a=100/2
a=50yds²
Let's take this problem step by step:
Step 1: First, the problem states that the caterer prepares four times as many pizzas as she usually prepares for a large party. It also states that she usually prepares six pizzas.
Step 2: 6 x 4 = 24
Step 3: The caterer estimates that each party guest will eat 1/4 of a pizza.
Step 4: 24 pizzas divided by 1/4 of a pizza is equivalent to 24/(1/4)
Step 5: You can take the reciprocal of 1/4 and multiply instead.
Step 6: 24 x 4 = 96
The answer is 96 party guests.
