Answer:
4 units
Step-by-step explanation:
Perimeter formula is P = 2L + 2W. Here P = 34 units = 2L + 2(6.5 units).
Reducing this, 17 = L + 13. Then L = 4 units.
Answer: 2 inch dimension will give smallest increase.
Step-by-step explanation:
Length = 3 in
width = 2 in
height = 6 in
Extra cardboard means to find surface area
on doubling the length
length = 6 In
width = 2 In
Height = 6In
Surface area for the above dimensions = 2 [ 6x2+2x6+6x6] = 120 sq in
On doubling the width
length = 3 in
width = 4 in
Height = 6 inch
Surface area for the above dimensions= 2 [ 3x4+4x6+6x3] = 2[54] = 108 sq inches
On doubling height
Length =3 in
width = 2 in
Height = 12 in
Surface area for above dimensions = 2 [ 3x2+2x12+12x3] = 2[6+24+36] = 132 sq inch
On doubling width surface area is minimum.
Answer:
163 lbs
Step-by-step explanation:
Since she weighs 177 lbs after birth, and they want to know how much she will weigh in 3.5 months with 4 lbs lost every month, here is the math:
4x3.5=14 lbs total
177 - 14lbs is 163
Assuming that a “circle graph” is a pie chart, the way of solving is this:
The degree of the angle of that pie section is relative to the entire circle just as the number of pyramids are to the number of total building blocks.
The number of pyramids out of the total is 30/150, or 1/5 (20%). This means that the angle of the section will be 1/5 the total angle measurement of the circle.
There are 360 degrees in a circle, and one fifth of this is 72 (360/5). Your answer is C.
