Step-by-step explanation:
A rectangular prism is 3 inches long, 5 inches wide, and has a height of 6 inches. What is its surface area?
The formula for the surface area of a rectangular prism =
A=2(wl+hl+hw)
Where
W= Width = 5in
H = Height = 6 in
l = Length = 3 in
Surface area =
2(5 × 3 + 6 × 3 + 5 × 6) square inches
2(15 + 18 + 30) square inches
2(63) square inches
= 126 square inches (in²)
Option D is correct

Label ABC with the following information.
AB = 35
AC = 62
Find m/c.
Answers
Answer:
m<C = 34.4 °
Step-by-step explanation:
From the question given above, the following data were obtained:
Opposite = AB = 35
Hypothenus = AC = 62
Angle C =?
The value of m<C can be obtained by using sine ratio as illustrated below:
Sine C = Opposite /Hypothenus
Sine C = 35 / 62
Sine C = 0.5645
Take the inverse of sine
C = Sine¯¹ 0.5645
C = 34.4 °
Thus,
m<C = 34.4 °
find the measure of this angle in the triangle

Answer: (x-6)(x+1)

x2 + x-=6 x − 6
factor pair: x 2 + x − 6 x − 6
x( x+ 1 ) − 6 ( x + 1 )
rewrite from: x (x + 1 ) − 6 ( x + 1 )
(x-6)(x+1)
Answer:
A: (x-6)(x+1)
Step-by-step explanation:
We need to find 2 numbers that add to make -5 and multiply to make -6.
We already have the numbers infront of us, so by process of elimination we can remove B and D.
For the numbers, we need a positive number and a negative number (two negatives make a positive). We can eliminate C because at first -3 multiplied by 2 is -6. However, when -3 is added to 2 we get -1.
If we expand A, it makes the expression that needs to be factorised because...
-6 × 1 = -6
-6 + 1 = -5
So expanding it properly we get.
x² - 6x + x - 6
Simplify.
x² - 5x -6

What is the volume of the hemisphere? 583.2cm^3cm 3 291.6cm^3cm 3 6882.3cm^3cm 3 3441.1cm^3cm 3 Item at position 3
Answers
Answer:
See Explanation
Step-by-step explanation:
The question has missing details; as the radius or an attachment of the hemisphere is not given.
However, I'll solve on a general terms.
The volume of a hemisphere is: [tex]V = \frac{2}{3}\pi r^3[/tex]
Take for instance
[tex]r = 14.9cm[/tex]
The volume becomes:
[tex]V = \frac{2}{3} * 3.142 * 14.9^3[/tex]
[tex]V = \frac{2 * 3.142 * 14.9^3}{3}[/tex]
[tex]V = \frac{20787.151516}{3}[/tex]
[tex]V = 6929.051cm^3[/tex]
So, all you need to do is plug in the value of radius in the formula.

Each term in the second factor is multiplied by each term in the first factor, that is
2x(4x - 3) + 5(4x - 3) ← distribute both parenthesis
= 8x² - 6x + 20x - 15 ← collect like terms

Can someone explain how to do this worksheet? when graphing the lines they don't seem to intersect with a UFO.
Answers

There are 2 equations together in each box, so what you need to do is graph them both. Then see where they intersect, that will be where the ufo they shot is. For example On the first two set of equations (y=x+6 & y=-x-4) when graphed together they intersect at (-5,1) which is where ufo 6 is. Meaning they shot Ufo 6

Jorge is using pencils at a rate of 6 packs a year or a rate of 2 packs every four months.
Step-by-step explanation:
1/3 of a year is four months so that would be 2 packs every four months and if you multiply that by three you’d get 12 month, or one year, and 6 packs of pencils.
