A teacher has two boxes. The first box has a height of 15 in., a width of 6 in., and a length of 8 in. The second box’s dimensions are twice that of the first box. How many times larger is the surface area of the second box than the first box?
A. The surface area of the second box is 6 times larger.
B. The surface area of the second box is 4 times larger.
C. The surface area of the second box is 3 times larger.
D. The surface area of the second box is 2 times larger.
Answer:
The correct option is B: the surface area of the second box is 4 times larger.
Step-by-step explanation:
The surface area of the first box is given by:
[tex] SA_{1} = 2l_{1}h_{1} + 2w_{1}h_{1} + 2l_{1}w_{1} [/tex]
Where:
l₁: is the length = 8 in
h₁: is the height = 15 in
w₁: is the width = 6 in
[tex] SA_{1} = 2*8*15 + 2*6*15 + 2*8*6 = 516 in^{2} [/tex]
The second box's dimensions are:
l₂ = 2*8 in = 16 in
h₂ = 2*15 in = 30 in
w₂ = 2*6 in = 12 in
Hence, the surface area of the second box is:
[tex]SA_{2} = 2*2l_{1}*2h_{1} + 2*2w_{1}*2h_{1} + 2*2l_{1}*2w_{1} = 4(2l_{1}h_{1} + 2w_{1}h_{1} + 2l_{1}w_{1}) = 4*SA_{1} = 4*516 in^{2} = 2064 in^{2}[/tex]
Therefore, the correct option is B: the surface area of the second box is 4 times larger.

A pan of brownies has an area of 7/8 ft2. Each brownie has an area of 1/16 ft2. Each brownie contains 250 calories. How many calories are in the entire pan of brownies? 3,500 cal 2,000 cal 4,000 cal 2,800 cal
Answer:
The answer is 3,500 calories
Step-by-step explanation:
The reason why is because the area of the pan is 7/8 and a brownie has a area of 1/16 that means 14 brownies can fit in the pan and because each brownie 250 calories that means 14x250=3,500 calories your answer.
Hopefully this helped give me 5 stars!

y varies directly with x. If y = 15 when x = -18, find y when x = 1.6.
Answer:
y= -1.328
Step-by-step explanation:
15= k*-18
15=k*-18 (divide both sides by -18)
It doesn't go in evenly so you are left with a negative decimal
k= -0.83
Now find y
y= -0.83(1.6)= -1.328

I need help on how to do these my teacher didn’t explain it to me
Answer:
Step-by-step explanation:
on the first one we see that they are outer angles and they are also congruent making the missing angle the same as 66
for the second one if we turn the graph around making the lines how a H shape we see the missing angle and the given angle are in the same line, and we know a straight line makes it 180, so we need to find what the other angle is using the given angle so we subtract from 180, 180-80 = 100
so the missing angle is 100 making it congruent to the other missing angle that was with the 80
for the last one by now we should know what vertical angles are, they are directly across from each other, and we see that they arent really like in the same part of the line, but we know that the one congruent to the 128 is the outer right angle, making the missing angle congruent because they are vertical angles making the missing angle 128 too

3,000 marbles in 200 jars
Answer:
15 marbles in a jar.
Step-by-step explanation:
[tex]\frac{y}{3000} :\frac{1}{200}[/tex]
y · 200 = 3000 · 1
200y = 3000

whats is the answer for 4x - 10 < 18
Answer:
x<7
Step-by-step explanation:
Answer: x=7, x<18, true
Step-by-step explanation: -10 becomes +10, then you add 10+18. 4x<28 is now the expressio. 28/4=7, x=7 and x or 7<28. This equation is true.
Find the equation of the line.

What is the solution set to the equation 4x2 – 16 = 0?
Answer:
2
Step-by-step explanation:
add 16 to zero
4x2=16
Divide 4x by 2 and 16 by two
4x=8
divide 8 by 4
x=2
Answer:
x = ± 2
Step-by-step explanation:
Given
4x² - 16 = 0 ( add 16 to both sides )
4x² = 16 ( divide both sides by 4 )
x² = 4 ( take the square root of both sides )
x = ± [tex]\sqrt{4}[/tex] = ± 2
solutions are x = - 2, x = 2

Can someone please help. Please show work
Answer:
11. parallelogram, rectangle
12. parallelogram, rhombus
13. parallelogram, square
For parallelogram:
In Euclidean geometry, a parallelogram is a simple (non-self-intersecting) quadrilateral with two pairs of parallel sides. The opposite or facing sides of a parallelogram are of equal length and the opposite angles of a parallelogram are of equal measure.
for rectangle:
A quadrilateral is a polygon in Euclidean plane geometry with four edges (sides) and four vertices (corners). Other names for quadrilateral include quadrangle (in analogy to triangle), tetragon (in analogy to pentagon and hexagon), and 4-gon (in analogy to n-gons for arbitrary values of n).
for rhombus:
In plane Euclidean geometry, a rhombus (plural rhombi or rhombuses) is a quadrilateral whose four sides all have the same length. Another name is equilateral quadrilateral, since equilateral means that all of its sides are equal in length. The rhombus is often called a diamond.
for Square:
·There are four methods that you can use to prove that a quadrilateral is a square. In the last three of these methods, you first have to prove (or be given) that the quadrilateral is a rectangle, rhombus, or both:
·If a quadrilateral has four congruent sides and four right angles, then it’s a square (reverse of the square definition).
·If two consecutive sides of a rectangle are congruent, then it’s a square (neither the reverse of the definition nor the converse of a property).
·If a rhombus contains a right angle, then it’s a square (neither the reverse of the definition nor the converse of a property).
·If a quadrilateral is both a rectangle and a rhombus, then it’s a square (neither the reverse of the definition nor the converse of a property).
The ratio of length to width in a rectangle is 3 to 1. If the perimeter of the rectangle is 120 feet, what is the length of the rectangle?
Answer:
a = length
b = height(width)
a=3b
2(a+b)=120
2(b+3b)=2(4b)=8b
8b=120
b=15
a=45
length is 45 feet
width is 15 feet

Step-by-step explanation:
whats 7 over 4 =35 over m in solving proportions NO LINKS PLZ
Hey there!
7/4 = 35/m
CROSS MULTIPLY BOTH of your NUMBERS
7(m) = 4(35)
7(m) = 7m
4(35) = 140
NEW EQUATION: 7m = 140
DIVIDE 7 to BOTH SIDES
7m/7 = 140/7
CANCEL out: 7/7 because that gives you 1
KEEP: 140/7 because that gives you the value of m
140/7 = m
Solve above and you have the answer of m
140/7 = 20
Therefore, the value of m = 20
Answer: m = 20
Good luck on your assignment and enjoy your day!
