Can anybody help me solve for surface area? The formula is the sum of the areas of the faces.
I will mark as brainliest ASAP!
Answer:
Surface area of the given prism = 63 square feet
Step-by-step explanation:
Surface area of the given triangular prism = Area of two triangular bases + Area of three vertical rectangles
Area of triangular bases = 2[[tex]\frac{1}{2}(\text{Base})(\text{Height})[/tex]] (Since the bases of this prism are right triangles)
= 3 × 3
= 9 square ft
Area of one vertical rectangular face = (Length × Width)
= (3 × 6)
= 18 square feet
Area of all vertical sides = 3 × 18 = 54 square feet
Total surface area = 9 + 54 = 63 square feet

A student was conducting a study to determine how many mini chocolate chip cookies would fit in a plastic sealed container. He used random packing to find the following.
Using the collected data above what would be a reasonable rough estimate of a ratio of how many cubic inches per cookie?
A. 2.2 in^3/cookie
B. 0.45 in^3/cookie
C. 17.82 in^3/cookie
D. 23.76 in^3/cookie
Answer: (A) [tex]2.2\text{ in}^3/\text{cookie}[/tex] .
Step-by-step explanation:
From the given table , the dimension of the container for the 90cookies = 11 inch x 6 inch x 3 inch
Then, the volume of the container would be [tex]11\times6\times3= 198 \ in^3[/tex]
Then, the ratio of cubic inches per cookie would be
[tex]=\dfrac{\text{Volume of container}}{\text{Number of cookies in it}}\\\\=\dfrac{198}{90}\\\\=2.2\text{ in}^3/\text{cookie}[/tex]
So, the the ratio of cubic inches per cookie would be [tex]2.2\text{ in}^3/\text{cookie}[/tex] .
Hence, the correct option is (A) [tex]2.2\text{ in}^3/\text{cookie}[/tex] .
What is the answer to this?
2x + 10 < 5x + 1
Answer:
x>3
Step-by-step explanation:
2x + 10 < 5x + 1
Add -5x and -10 on both sides of the inequality.
2x + 10 -10 -5x < 5x + 1 -5x -10
2x -5x < 1 -10
Subtract like terms.
-3x < -9
Multiply -1 and reverse the inequality.
3x>9
Divide 3 into both sides of the inequality.
3x/3>9/3
x>3
Answer: x > 3
Step-by-step explanation: Put your x's together on the left side of the inequality by subtracting 5x from both sides to give you -3x + 10 < 1.
Next, put your numbers together on the right by
subtracting 10 from both sides and we have -3x < -9.
To get x by itself, divide both sides by -3, but watch out.
If you multiply or divide both sides of an inequality by a negative,
you must switch the direction of the inequality sign.
Please give this idea your full attention.
Even the most advanced algebra students will sometimes forget to
switch the direction of the inequality sign when multiplying or
dividing both sides of an inequality by a negative.
So we have x > 3 as our answer.
I have graphed the solution below.
5 – 6x = 8x + 17 and simplify [tex]\frac{-6}{7}[/tex]
Answer:
x = -6/7
Step-by-step explanation:
5 – 6x = 8x + 17
-5 - 5 Subtract 5 from both sides
-6x = 8x + 12
-8x - 8x Subtract 8x from both sides
-14x = 12 Divide both sides by -14
x = -12/14 Simplify
x = -6/7

Right the slope form of a line with a slope of 2 and a Y intercept form of -4
Answer:
y = 2x - 4
Step-by-step explanation:
Slope intercept form should be the easiest because they give you all you need.
y = mx + b
m = 2
b = -4
y = 2x - 4
Please answer correctly !!!!!!!! Will mark brianliest !!!!!!!!!!!
Answer:
x=6
Step-by-step explanation:
h(x) = -( x-2)^2 +16
We want when h(x) = 0
0 = -( x-2)^2 +16
Subtract 16 from each side
-16 = -( x-2)^2 +16-16
-16 = -( x-2)^2
Divide by -1
16= ( x-2)^2
Take the square root of each side
±sqrt(16) = sqrt(( x-2)^2 )
±4 = x-2
Add 2 to each sdie
2 ±4 = x-2+2
2+4 = x 2-4 =x
6 =x -2 =x
since time cannot be negative
x=6
Which unit would you use to measure the weight of a car?
O mg
O kg
O g
O km
Answer:
The weight of an object is defined as the force of gravity on the object and may be calculated as the mass times the acceleration of gravity, w = mg. Since the weight is a force, its SI unit is the newton.

The volume of a box containing 15 identical cubes is 295245cu.m. Find the edge of the cube.
Answer:
Edge length of the cube = 27 m
Dimensions of the box is length = 135 m, width = 81 m, height = 27 m
Step-by-step explanation:
The box contains 15 identical cubes therefore, we have
Edge length of cube = Side, s, of cube
15 × s³ = 295245 m³
∴ s³ = 295245/15 = 19683 m³
s = ∛19683 = 27 m
Hence the edge length of the cube = 27 m
The dimension of the box is length = 5 × 27 = 135 m
Width = 3 × 27 = 81 m
height = 27 m.

Answer:
6^21 = B
Step-by-step explanation:
[tex][6^{7} ]^{3} \\(6)^7^*^3\\6 ^{21} \\[/tex]
Answer:
B
Step-by-step explanation:
When solving exponents with parenthesis around the base + sub exponent, always multiply the two exponents. Basically, when the two exponents are right next to each other, you multiply them. When you multiply 7 and 3, you get 21; therefore, the answer is 6 to the power of 23.

1 / cosec A -1 - 1 / cosec A + 1
Answer:
Given expression is [tex]\frac{1}{\text{cosec}A-1}-\frac{1}{\text{cosecA+1}}[/tex] = 2tan²A
We have to prove this identity.
[tex]\frac{1}{\text{cosec}A-1}-\frac{1}{\text{cosecA+1}}=\frac{(\text{cosecA+1})-(\text{cosecA-1})}{(\text{cosecA-1})(\text{cosecA+1})}[/tex]
= [tex]\frac{(\text{cosecA}-\text{cosecA})+(1+1)}{cosec^2A-1}[/tex]
= [tex]\frac{2}{cosec^{2}A-1}[/tex]
= [tex]\frac{2}{cot^{2}A}[/tex] [From the identity, (cosec²A - 1) = cot²A]
= 2tan²A [From the identity, cotA = [tex]\frac{1}{\text{tan}A}[/tex]]
Hence the given equation is proved.
