Answer:
Step-by-step explanation:
You can make 1.4 as a fraction, and it will be the same but in a different form.
So, to make a decimal by a fraction, you make 1.4 into a whole number. 1.4 will be 14.
Now, the denominator will be 10.
So, when you simplify , which is
Answer:
Step-by-step explanation:
x² + 5x + 3 = 0
x = (- 5 +/- √5² - 4x1x3)/2x1
= (-5+/-√13)/2
x₁ = (- 5 + √13)/2
x² = (- 5 - √13)/2
Speed is given by:
speed=distance/time
given that:
1 mile=1,760 yards
1 hour=60 min
then the speed in yards/sec will be:
distance Ashley covered is 15 miles
time=2 hours
thus;
speed=(15x1760)/(2x60)
=220 yards/ min
<span>Length = l</span>
<span>
Width = w</span>
<span>
Perimeter = p = 100
</span>
<span>Perimeter of rectangle = 2(l+w)</span>
<span>
100 = 2 (4w + w)</span>
<span>
100 = 2(5w)</span>
<span>
100 = 10w</span>
<span>
100/10 = w</span>
<span>
10 = w</span>
<span>
w = 10
Area of rectangle = length * width</span>
<span>
a = l*w</span>
<span>
a = 4w*w</span>
<span>
a = 4w^2............(1)</span>
<span>
Put the value of w in (1)</span>
<span>
a = 4(10)^2</span>
<span>
a= 4(100)</span>
<span>
a = 400 yd^2</span>
so you have a 148+85+85=318, 360-318=42 is the measure of angle T because all four angles together make 360
