(25% of 1)
means 25/100 *1
= 25/100
= 0.25
2/5 ÷ 0.25
2/5 = 0.4
0.4 / 0.25
<h3><u>= 1.6</u></h3>
Answer:
B
Step-by-step explanation:
Since the value of a is less than 0, the graph of the parabola would be opening downwards. Because of this we can rule out option C. In a quadratic equation, c represents the y-intercept, and, in this case c is negative, meaning the y-intercept is less than 0. Only option B has a downward-opening curve and a y-intercept less than 0, so it is the answer.
Answer:
40,60,80
Step-by-step explanation:
2x+3x×4x=180
9x=180
x=20
2x=40
3x=60
4x=80
-5x - 7 < 28.....add 7 to both sides
-5x < 35....divide both sides by -5, change the inequality sign (u change the inequality sign when dividing/multiplying by a negative number)
x > -7
Answer:
4.255 ft²
Step-by-step explanation:
the area of the figure =
(2.25 × 1.5)+(1/8 ×3.14× 1.5²)
= 3.375 + 0.88
= 4.255 ft²
