Can someone help me
Answer:
it's d
Step-by-step explanation:
because you first do 3*4 =12 twice because there are two sides, and do 10*3 twice, and 10*4 twice, and add it all up.
so,
24+60+80=164
answer is d.
Answer:
Option D, [tex]164\ units^2[/tex]
Step-by-step explanation:
Step 1: Determine the area of the front and back
[tex]A = l * w[/tex]
[tex]A = 10\ units * 4\ units[/tex]
[tex]A = 40\ units^2[/tex]
Step 2: Determine the area of the sides
[tex]A = l * w[/tex]
[tex]A = 3\ units * 4\ units[/tex]
[tex]A = 12\ units^2[/tex]
Step 3: Determine the area of the top and bottom
[tex]A = l * w[/tex]
[tex]A = 10\ units * 3\ units[/tex]
[tex]A = 30\ units^2[/tex]
Step 4: Determine the total surface area
[tex]SA = 2(40\ units^2) + 2( 12\ units^2) + 2(30\ units^2)[/tex]
[tex]SA = 80\ units^2 + 24\ units^2 + 60\ units^2[/tex]
[tex]SA = 164\ units^2[/tex]
Answer: Option D, [tex]164\ units^2[/tex]

Which statement describes the solutions of this equation?
x/x+2+1/x=1
Answer:
~Senpi boi here~
Step-by-step explanation:
Multiply all terms by x and cancel:
x+2x+1=1x
3x+1=x(Simplify both sides of the equation)
3x+1−x=x−x(Subtract x from both sides)
2x+1=0
2x+1−1=0−1(Subtract 1 from both sides)
2x=−1

A line passes through the pointa (-8,8) and (12,7)
Answer: y= -1/20x + 38/5
or
y= -1/20x + 7.6
Step-by-step explanation:
y-y1 = m(x-x1)
m = 8-7 / -8 - 12 = 1/-20 = -1/20
y-8 = -1/20(x+8)
y=-1/20x - 8/20 + 160/20
y= -1/20x + 38/5
or
y= -1/20x + 7.6

A rectangular prism has dimensions x units, 2x units, and x 8 units. which expression represents the surface area of the prism? 8x 16 square units 16x 32 square units 10x2 48x square units 2x3 16x2 square units
The rectangular prism with dimensions x units, 2x units, and x- 8 units has a surface area of 10x^2 - 48x square units
Volume of a rectangular prismThe formula for calculating the suface area of rectangular prism is expressed as:
A =2()
lw + wh + lh
where:
l is the lengthw is the widthh is the heightGiven the following parameters
l = x units
w = 2x units
h = x - 8 units
Substitute
S = 2(2x^2 + x^2 - 8x + 2x^2 - 16x)
S = 2(5x^2-24x)
S= 10x^2 - 48x square units
Hence the rectangular prism with dimensions x units, 2x units, and x- 8 units has a surface area of 10x^2 - 48x square units

Use the discriminant to determine how many and what kind of solutions the quadratic equation x^2 - x = 1 has.
1. no real or complex solutions
2. two complex (nonreal) solutions
3. one real solution
4. two real solutions
Answer:
4. two real solutions
Step-by-step explanation:
[tex]x^2 - x = 1[/tex] (Given)
[tex]\implies x^2-x-1=0[/tex]
Equating it with [tex]ax^2+bx+c=0[/tex]We find: a = 1, b = -1, c = -1Next, we calculate the discriminant of the given quadratic equation by plugging the values of a, b and c in the formula [tex]\implies b^2-4ac[/tex][tex]b^2-4ac\\=(-1)^2-4(1)(-1)\\=1+1=2>0\\\implies b^2-4ac >0[/tex]

an experiment requires the population of the bacteria to reach 2 million before the experiment can begin. The reproduction rate of the bacteria can be modeled by the exponential equation Y= 8 times 7^x. About how many hours X will it take for the bacteria population to reach 2 million?
round your answer the the nearest hour
Answer:
about 6 hours
Step-by-step explanation:
[tex]8( {7}^{x} ) = 2( {10}^{6} )[/tex]
[tex] {7}^{x} = 250000[/tex]
[tex]x = \frac{ ln(250000) }{ ln(7) } = 6.39[/tex]
The about 6 hours the bacteria population to reach 2 million.
What is exponential equation?An exponential equation is an equation with exponents where the exponent (or) a part of the exponent is a variable.
Given that the experiment requires the population of the bacteria to reach 2 million before the experiment can begin.
The reproduction rate of the bacteria can be modeled by the exponential equation,
y = 8 × 7ˣ.
So, according to the question,
8 × 7ˣ = 2 × 10⁶
7ˣ = 250000
x ≈ 6.4
Hence the about 6 hours the bacteria population to reach 2 million.
