Answer: if you times 12x2.75 I got 33 some she can spend $33.00 and not go over.
Answer:
The width is 20 ft and the length is 80 ft
Step-by-step explanation:
Area = l * w
l = w +60
SA = 1600 ft^2 ( which is the regular area) The surface area of the water is just what is on top which is length times width
1600 = l*w
Substitute in l = w+60
1600 = (w+60) *w
Distribute the w
1600 = w^2 +60w
Subtract 1600 from each side
1600-1600 = w^2 + 60w -1600
0 = w^2 + 60w -1600
Factor
0=(w-20) (w+80)
Using the zero product property
w-20=0 w+80 =0
w=20 or w=-80
The width cannot be negative so
w=20
Now we need to find the length
l = w+60
l = 60+20
l =80
<span>It is known that 1 mile = 1.609 kilometers. So the distance between these two cities, in kilometers, is equal to 140*1.609, which gives us ~225km.</span>
Answer:
B.)
Step-by-step explanation:
In step #1 they did the distributive property
2/5 × 15x = 6x
2/5 × -30y = -12y
The new equation would be:
6x - 12y + 10x
<em><u>Further</u></em><em><u> </u></em><em><u>Explanation</u></em>
They then combined 6x + 10x to get 16x
16x - 12y
They then factored it out to 4(4x - 3y)
Answer:
A.
Step-by-step explanation:
The triangles are the rise and run of the same line. They are different sizes, but the angles are congruent.
