Find the area of each triangle to the nearest tenth.

9. 60.5 cm 10. 30 mi

Step-by-step explanation:

The equation for the area of a triangle is:

Base×Height÷2

9.

1. plug in the numbers with Base×Height÷2: 11×11÷2

2. solve: 11×11=121

3. 121 ÷ 2 = 60.5

60.5 cm

10.

1. plug in the numbers with Base×Height÷2: 5×12÷2

2. solve: 5×12= 60

3. 60÷2=30

30 mi

3< x< 5

step-by-step explanation:

|x - 4| < 1

there are two solutions, one positive and one negative.   remember to flip the inequality when taking the negative solution

x-4 < 1       x-4 > -1

add 4 to each side

x-4+4 < 1+4       x-4+4 > -1+4

x< 5                 x> 3

3< x< 5

you never say the total so we cant find the percentage used for petrol
