A box shaped like a rectangular prism has a height of 17 in and a volume of 2.720 in^3. The length is 4 inches greater than twice the width. What is the width of the box?
O -10 in
O 8 in
O 20 in
O 40 in
Answer:
8
Step-by-step explanation:
Height, h = 17
Let :
Width = x
Length = 2x + 4
Volume = 2720 in³
Volume of rectangular prism = Length * width * height
2720 = 17 * x * (2x + 4)
2720 = 34x² + 68x
34x² + 68x - 2720 = 0
x² + 2x - 80 = 0
x² + 10x - 8x - 80 = 0
x(x + 10) - 8(x + 10)
(x + 10) = 0 or (x - 8) = 0
X = - 10 or x = 8
Width can't be negative
Hence, width, x = 8
Find the distance between the two points.
(-1, -3), (1, 3)
The distance between the two points is
units.
Answer:
The distance between those points is 6.32456. You can just round it if they want you to round the number.
Step-by-step explanation:
1. (x2-x1) = (1 - -1) = 2
2. (y2-y1) = (3 - -3) = 6
3. (2)^2 + (6)^2 = 4 + 36 = 40
4. √40 = 2√10
5. 6.3246

Answer:
12:15 is NOT proportional to 3:4
Step-by-step explanation:
7.5:10 is proportional to 3:4 because 3×2.5=7.5, and 4×2.5=10.
39:52 is proportional to 3:4 because 3×13=39, and 4×13=52
45:60 is proportional to 3:4 because 3x15=45, and 4×15=60
12:15 is not proportional to 3:4 because while you can multiply 3x4=12, you can not multiply 4×4 to get 15, you get 16 instead.
the answer to your question is D.12:15

x = 40
Step-by-step explanation:
40° and (3x + 20)° form a straight line, and a straight line equals to 180°
=> 40 + (3x + 20) = 180
=> 3x = 120
=> x = 40

3. If the circumference of a circle is 44 m, find its area.
[tex]\pi[/tex]
Answer:
[tex] \huge\blue{ \mid{ \underline{ \overline{ \tt ♡ ANSWER : ♡ }} \mid}}[/tex]
Circumference of the circle = 44 m
Circumference Formula = 2πr
Let's take the radius as 'r' m.
Radius (r) =
[tex]2πr = 44 \\ 2 × 3.14 × r = 44 \\ r = 44/6.28 \\ r = 7 \: m.[/tex]
Area of the circle = πr²
[tex] = 3.14 × 7² \\ = 153.86 \: m ^{2} [/tex]
=> Area of the circle = 153.86 m² = 154 m² (approx.)

find the volume of the composite figure
Answer:
8064
Step-by-step explanation:
Multiply all the sides
6x4x12x2x14
Answer:
384 cu. cm
Step-by-step explanation:
The figure is comprised of two rectangular prisms. One prism has dimensions of 6, 4 and 2 and the other prism has dimensions of 14, 12 and 2
Vol of a rectangular prism = lwh
Total volume = 6(4)(2) + 14(12)(2)
= 48 + 336
= 384 cu. cm
how do you simplify 3(j-2k)+4 ?
Answer: 3j-6k+4
Step-by-step explanation:
First you have to distribute the 3 to the j and the -2k since they are both in the parentheses. So it would look like (3*j) +(-2k*3)+4 and if you simplify that it is 3j-2k+4. After that there are no like terms so that is your answer.
Ryan conducted a 6-day study observing the effects of an organic plant food on the growth of his sprouting bean plant. He tracked these two pieces of information: the amount of plant food remaining in the container after each day's feeding the height of the plant over time
Answer:
[tex]Domain : 0\le x \le 6[/tex]
[tex]Range: 0 \le y \le 72[/tex]
Step-by-step explanation:
Given
See attachment for complete question
Required
Determine the domain and the range
From the complete question, we understand that the study was carried out for 6 days. This represents the domain;
So, we have:
[tex]Domain : 0\le x \le 6[/tex] i.e. from day 0 to day 6
Also, he experimented with 72ml, and he used an equal amount each day before he used up all the 72mL. This represents the range
So, the range is:
[tex]Range: 0 \le y \le 72[/tex] i.e. from 72mL to 0mL
