Alright I know what your all thinking the answer is 2, but it says I’m wrong. Am I doing something wrong?
Answer:
3.75
Step-by-step explanation:
Follow PEMDAS
P = parentheses so first it will turn to 30 divided by 3 times 5
E = exponents we dont have any
M = multiplication 30 divided by 8
D = division = 3.75
Find the equation of the line through (0,-2) and (4, 18).
Let me = slope
m = (18 - (-2))/(4 - 0)
m = 20/4
m = 5
We now plug slope 5 and one of the given points into the point-slope formula.
y - y_1 = m(x - x_1)
y - 18 = 5(x - 4)
y - 18 = 5x - 20
y = 5x - 20 + 18
y = 5x - 2

Akio buys scissors for $3.79, tape for $2.57, and pens for $5.80. The sales tax is 6.25%.
What is the amount of tax for Akio's purchases?
Enter your answer in the box
Answer:
$0.76
Step-by-step explanation:
3.79+2.57+5.8=12.16
12.16 x 0.0625=0.76
To solve this, you have to add all the prices together and then convert the percentage into a number so that you can multiply it by the total sales. You end up with 0.76 cents as the taxes for Akio's Purchase.You convert the percentage by moving it backward 2 decimal places.
Answer:

x + y = 4.25
16.90x + 4y = 36.35
Answer:
x=1.5 y=2.75
Step-by-step explanation:
Answer:
Step-by-step explanation:
use the first equation to solve the second equation
y = 4.25 - x
16.90x + 4(4.25 -x) = 36.35
16.90x + 17 - 4x = 36.35
12.90x = 19.35
x = 1.5
y = 4.25-1.5
y= 2.75
x=1.50
y=2.75

What is the equation of a line parallel to Y=-3x+5 that passes through point (6,8)?
9514 1404 393
Answer:
y = -3x +26
Step-by-step explanation:
We assume the given line is ...
y = -3x +5
This is in slope-intercept form:
y = mx +b
where m = -3 and b = 5.
The parameter m represents the slope of the line. A parallel line will have the same slope, so will be of the form ...
y = -3x +b
We can find the value of b using the given point:
8 = -3(6) +b
26 = b . . . . . . add 18
So, the equation of the parallel line through (6, 8) is ...
y = -3x +26

Answer:
D. [tex]2^{18}[/tex]
Step-by-step explanation:
The expression is: [tex](2^{6}) ^{3}[/tex] * [tex]2^{0}[/tex]
For the first term: When a term with an exponent is inside parentheses with another exponent on the outside, the two exponents are multiplied by each other:
6 * 3 = 18
Now the expression looks like this: [tex]2^{18}[/tex] * [tex]2^{0}[/tex]
Any number to the power of zero is 1.
So the equation now looks like this: [tex]2^{18}[/tex] * 1
After you multiply the two terms, you end up with [tex]2^{18}[/tex].
Answer:
The answer is D 2^18

a regular pentagon and an equilateral triangle have the same perimeter...........
(Please don't answer with anything that doesn't relate to it, such as no mimicking please i beg you)
I only have 1 hour before class help please
Answer:
Option 4: 45 units is the correct answer
Step-by-step explanation:
Let [tex]P_1[/tex] be the perimeter of Pentagon and
Let P2 be the perimeter of Triangle
So,
[tex]P_1 = 5(\frac{1}{2}x-1)\\P_2 = 3(x-5)[/tex]
In order to find the perimeter of each figure we have to put both the expressions equal so that the value of x can be found and then perimeter.
So,
[tex]P_1 = P_2\\5(\frac{1}{2}x-1) = 3(x-5)\\\frac{5}{2}x-5 = 3x-15\\\frac{5}{2}x-3x = -15+5\\\frac{5x-6x}{2} = -10\\-\frac{x}{2} = -10\\-x = -10 * 2\\-x = -20\\x = 20[/tex]
Putting x = 20 in 2nd perimeter
[tex]P_2 = 3(x-5) \\= 3(20-5)\\= 3(15)\\=45[/tex]
As both the perimeters are same, the perimeter of pentagon will also be 45 units.
Hence,
Option 4: 45 units is the correct answer

How can you tell if an expression is a monomial , binomial or trinomial?
Answer:
Look at the Latin root. Mono means one, so [tex]2x^{2}[/tex] is an example because it is only made up of one term. Bi means two, so [tex]3x^{3}[/tex]+4 is an example because it was two terms. Tri means three, so there needs to be three terms for it to be a trinomial. [tex]2x^{5}[/tex]-3x+5 is an example of a trinomial because it was three terms within the equation.

Twice a number increased by 1 is -11. Find the number.
Answer:
x=-6
Step-by-step explanation:
Twice mean multiply by 2
and twice a number is 2x (If you let x be the "number")
increase means adding by
increase by 1 is adding by 1
Is means =
is -11 is
=-11
now that we have all the things we add it up
Wice a number increased by 1 is -11:
2x+1=-11
Now you move the 1 to the other side by subtracting by 1 on both sides:
2x+1-1=-11-1
Simplify:
2x=-12
divide both sides by 2:
x=-6

Step-by-step explanation:
y= 3x + 2 and y= 3x -3. These lines are...
parallel
perpendicular
neither
The lines y= 3x + 2 and y= 3x -3 are parallel because the slope of the lines is an equal option (A) is correct.
What is a linear equation?It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.
It is given that:
The equation of the lines:
y = 3x + 2 and y = 3x - 3
The slope of the line:
y = 3x + 2
y = mx + c
m = 3
The slope of the line:
y = 3x - 3
y = MX + C
M = 3
m = M
The slopes of the line are the same.
Thus, the lines y= 3x + 2 and y= 3x -3 are parallel because the slope of the lines is an equal option (A) is correct.

Answer:
Integers are 7, 8, 9
Step-by-step explanation:
Let three positive consecutive integers are (n - 1), n, (n + 1)
If the product of the second and the third integer is 72,
n(n + 1) = 72
n² + n = 72
n² + n - 72 = 0
n² + 9n - 8n - 72 = 0
n(n + 9) - 8(n + 9) = 0
(n - 8)(n + 9) = 0
(n - 8) = 0 ⇒ n = 8
(n + 9) = 0 ⇒ n = -9
For n = 8,
Integers will be ⇒ 7, 8, 9
For n = -9,
Integers will be ⇒ -10, -9, -8
Since, all integers are positive,
7, 8, 9 will be the answer.
Evaluate the logarithm.
log9(1/81)
a. 2
b. -2
The solution of the logarithmic functions [tex]log_9 ( \dfrac{1}{81} )[/tex] would be, - 2. Hence option b is true.
Given that,
The expression is, [tex]log_9 ( \dfrac{1}{81} )[/tex].
Used the formula of logarithmic functions that are,
[tex]log (m^n) = n log m[/tex]
And, [tex]log_a (a) = 1[/tex]
Now, simplify the given logarithmic functions by using the above formula,
[tex]log_9 ( \dfrac{1}{81} )[/tex]
[tex]log_9 ( 81 )^{-1}[/tex]
[tex]log_9 ( 9^2)^{-1}[/tex]
[tex]log_9 ( 9)^{2 \times -1}[/tex]
[tex]log_9 ( 9)^{-2}[/tex]
Apply the formula [tex]log (m^n) = n log m[/tex],
[tex]- 2 log _ 9 (9)[/tex]
Since, [tex]log_a (a) = 1[/tex]
Hence, it can be written as,
[tex]- 2 log _ 9 (9)[/tex]
[tex]- 2 \times 1[/tex] [tex]= - 2[/tex]
Therefore, the solution is,
[tex]log_9 ( \dfrac{1}{81} ) = - 2[/tex]

56.52
Hemisphere: 56.52
320 + 56.52 = 376.52
The volume of the composite figure is 376.52 [tex]cm^{3}[/tex].
What is volume of hemisphere?The total space occupied by a hemisphere in a 3-dimensional region is called its volume. Geometrically a hemisphere is an exact half of a sphere.
Volume of hemisphere = [tex]\frac{2}{3} \pi r^{3}[/tex]
What is volume of cuboid?The volume of the cuboid is the measure of the space occupied within a cuboid. The cuboid is a three-dimensional shape that has length, breadth, and height.
Volume of cuboid = Length × Width × Height
Given
Radius of hemisphere r = 3
Volume of hemisphere = [tex]\frac{2}{3} \pi r^{3}[/tex]
Volume of hemisphere V1= [tex]\frac{2}{3} \pi r^{3}[/tex]
= [tex]\frac{2}{3} .(3.14).(3)^{3}[/tex]
= 56.52 [tex]cm^{3}[/tex]
Volume of cuboid V2 = Length × Width × Height
= 10 × 8 × 4
= 320 [tex]cm^{3}[/tex]
The volume of the composite figure V = V1 + V2
V = 56.52 + 320
V = 376.52 [tex]cm^{3}[/tex]
Hence, the volume of the composite figure is 376.52 [tex]cm^{3}[/tex].
