First, Jane must know the volume of the box.
Volume = l * w * h
Volume = 1 * 0.5 * 0.5
Volume = 0.25 yard^3
1 yard^3 = $25
So,
1 : 25 = 0.25 : x
x = 25 * 0.25
x = $6.25
So she need to spend $6.25
Answer:
16/13
Step-by-step explanation:
the error is when it was divided, one of the fractions should be reversed to be multiplied
<u> </u><u>4</u><u> </u><u> </u> ÷ <u> </u><u>1</u><u>3</u><u> </u>
7. 28
<u> </u><u>4</u><u> </u> × <u>2</u><u>8</u><u> </u> ,like this
7. 13
= <u> </u><u>1</u><u>1</u><u>2</u><u> </u> ,divide both by 7
91
= <u> </u><u>1</u><u>6</u><u> </u>
13
Answer:
Yes
Step-by-step explanation:
Graph this function on your calculator and you will see an upwards graph, if the range (y), -1 can be mapped on the graph, it is within the range.
Answer:
x+1 , x<-1
x²-bx-4 , -1≤x≤4
1/2 x +a
substitute x=-1 , continuous everywhere
x+1=x²-bx-4 when x=-1
-1+1=-1²-b-4
<h2>1+b-4=0 ⇒ +b-3 ⇒ b=3</h2>
then for :
x²-bx-4=1/2 x +a for x=4
4²-4b-4=1/2x+a
16-4(3)-4=4/2+a
16-12-4-2=a
<h2>a=-2</h2>
the equations will be :
x+1
x²-3x-4
1/2x-2
I hope this help
Answer:
x = 5.5 (Fraction 5 and one-half)
Step-by-step explanation:
18 - 7x = -20.5
-18 -18
-7x = -38.5
/-7 /-7
x = 5.5
