Area of rectangle = l × b = 16 × 8 = 128cm²
Area of 1 triangle = ½ × b × h = ½ × 2 × 2 = 2cm²
Area of 4 triangle = 2cm² × 4 = 8cm²
Area of shaded region
= Area of rectangle - Area of 4 triangle
= 128cm² - 8cm²
= 120cm²
Hello.
First of all, let the number be t.
8 times t can be written like this:
Notice that the number is before the variable and the times sign (×) is not there.
We can write it as 8×t, but we usually write it as 8t.
The sum of means we add:
8t+21
Now, "less than" is "<" :
Therefore, the answer is
I hope it helps.
Have a nice day.
Less then i really hope i helped
Answer:
BC = 107
Step-by-step explanation:
Point B is between A and C.
AB = 3x-1
BC = 9x+8
AC = 139
We need to find BC for which we need to find x first.
<u>Finding 'x':</u>
We know that AB + BC = AC
*putting the values of AB, BC and AC*
3x-1+9x+8 = 139
12x+7=139
12x=132
x=132/12
x=11
Now, BC = 9x+8 = 9(11) +8
BC = 99+8
BC = 107
Answer:
The interest after 54 month is $2970 and the rate is 4%.
Step-by-step explanation:
The amount of interest gathered in 54 months is equal to the final amount subtracted by the initial one. We have:
interest = 19470 - 16500
interest = $2970
In order to calculate the rate we need to apply the formula for simple interest shown below:
interest = C*r*t
Where C is the initial amount, r is the rate of interest and t is the time elapsed in years. We have:
2970 = 16500*r*(54/12)
2970 = 16500*r*(4.5)
74250*r = 2970
r = 2970/74250
r = 0.04
The rate is r*100% = 4% per year.
