Answer:
5 units
Step-by-step explanation:
Area of triangle = 1/2 × base × height
30 = 1/2 × 12 × height
Height = 30 × 2/12 = 5 units
solution: Mr. Schwartz will need to order more wheels after building 12 cars.
explanation:
Mr. Schwartz begins with total number of wheels = 85
he has to order more wheels once he left with less than 40 wheels
so min. no. of wheels he can use before ordering more wheels = 85-40 = 45
Mr. Schwartz uses 4 wheels to build 1 car
Mr. Schwartz uses 45 wheels to build 45÷4 = 11.25 cars
then, if he builds 12 cars then he needs 12×4 = 48 wheels
total supply of wheels he begins with = 85
wheels he used to build 12 cars = 48
so total number of wheels remaining are = 85-48 = 37
since 37 is less than 40 so after building 12 cars Mr. Schwartz need to order more wheels.
Answer: Right angles
Step-by-step explanation:
Answer:
x-9 = 9 x-9 = -9
Step-by-step explanation:
(x - 9)^2 = 81
Take the square root of both sides
sqrt((x - 9)^2) = ±sqrt(81)
x-9 = ±9
x-9 = 9 x-9 = -9
Answer:
Step-by-step explanation:
- <em>When planes intersect it forms a line that belongs to both planes</em>
In this case we have the plane P and the plane with B, C, D points on it
The intersection line is BC as we see on the picture
