Answer:
i believe the answer would be 12 x 6 = n.
if 50% is 15 what is 75%
Answer:
22.5
Step-by-step explanation:
50% of a number is 15
let the unknown number be = x
[tex] \frac{50}{100} \times x = 15[/tex]
[tex]x = 15 \div \frac{50}{100} [/tex]
[tex]x = 15 \times \frac{100}{50} [/tex]
[tex]x = \frac{1500}{50} [/tex]
[tex]x = 30[/tex]
75% of 30:
[tex] \frac{75}{100} \times 30 = 22.5[/tex]

AB is congruent to AD so let's solve the equation:
[tex] \: \: \: \: \: \: \: \: \: \: \: 8x - 2 = 6x + 4 \\ \frac{ - 6x \: \: \: \: \: \: \: \: \: \: \: = - 6x}{2x - 2 = 4} \\ \frac{ \: \: \: \: \: \: \: \: \: \: + 2 = + 2}{ \frac{2x}{2} = \frac{6}{2} } \\ x = 3[/tex]

Please answer this correctly without making mistakes
Answer:
2 pt + 1c
Step-by-step explanation:
There are 2 cups in a pint. So, 2c = p, dividing 2 from both sides, we get
c = (1/2)p
Replace c with 1/2 p in the equation
5 pt - (2pt + (1/2)p)
= 5pt - 2pi - (1/2)p
= 3pt - (1/2)p
= 2pt + (1/2)p
Replace back (1/2)p for c
2pt + (1/2)p =
2 pt + 1c

Answer:
[tex]P(x) = 16x - 100 - 0.1x^2[/tex]
Step-by-step explanation:
Given
[tex]R(x) = 46x[/tex]
[tex]C(x) = 100 +30x +0.1x^2[/tex]
Required
Determine the profit function
This is calculated as follows:
[tex]P(x) = R(x)- C(x)[/tex]
Substitute values for R(x) and C(x)
[tex]P(x) = 46x - (100 + 30x + 0.1x^2)[/tex]
Open bracket
[tex]P(x) = 46x - 100 - 30x - 0.1x^2[/tex]
Collect like terms
[tex]P(x) = 46x - 30x - 100 - 0.1x^2[/tex]
[tex]P(x) = 16x - 100 - 0.1x^2[/tex]
Find the slope intercept equation of the line
Answer:
I know that the y-intercept is 5
Step-by-step explanation:
because the line goes through 5
Answer:
y = -4/5x + 5
Step-by-step explanation:
You need the equation y = mx + b
the y intercept is 5 which is b
You just need to pick any point on the line and use those coordinates to plug into the equation for x and y to solve for the slope (m)
I will use point (5, 1)
So plugging in that coordinate and the value for b in the equation
y = mx + b is (1) = m(5) + 5
Solve for m m= -4/5
so plug m and b back into the equation y = mx + b
is
y = -4/5x + 5
Find the area of the composite figure. Write just the answer in the blank.
Answer: 297 yd
Step-by-step explanation:
You need to find the area of the rectangle and triangle then add both areas together to find the total area of the composite figure.
Area of rectangle: 12 x 18 = 216
Area of triangle: 81
A = 1/2bh
A = 1/2 x 18 x 9
A = 81
Total area of composite figure: 216 + 81 = 297

The value of the given expression −(8 − 12) + 60 + (−4)² will be 80.
What is the arithmetic operator?Arithmetic operators are operators in mathematics where basic four operators involve. Addition, multiplication, division, and subtraction.
Addition = addition of two or more numbers or variable
For example =3 + 4
Subtraction = Minus of any two or more numbers with each other called subtraction.
For example =8 - 9
Division = divide any two numbers or variable called division.
For example 7/3
Multiplication = to multiply any two or more numbers or variables called multiplication.
For example 5 × 4.
Given,
⇒ −(8 − 12) + 60 + (−4)²
⇒ -(-4) + 60 + 16
⇒ 4 + 60 + 16
⇒ 80
Hence "The value of the given expression −(8 − 12) + 60 + (−4)² will be 80".

PLEASE ANSWER THIS ASAP, I WILL BE GIVING YOU A THANKS! .
Answer:
D.) 12
Step-by-step explanation:
16x - 3(4x + 5) = 2x + 9
16x - 12x - 15 = 2x + 9
4x - 2x = 15 + 9
2x = 24
2x/2 = 24/2
x = 12
Check:
16x - 3(4x + 5) = 2x + 9
16(12) - 3(4(12) + 5) = 2(12) + 9
192 - 3(48 + 5) = 2(12) + 9
192 - 3(53) = 24 + 9
192 - 159 = 33
33 = 33
Write the equation of a line that is perpendicular to y=7x−2 and passes through the point (14,8).(1 point) y=7x−90 y=10x−17 y=−17x+1067 y=−17x+10
Answer:
[tex]\huge\boxed{y=-\frac{1}{7}x+ 10}[/tex]
Step-by-step explanation:
In order to find the equation of this line, we need to note two things.
A) The slope of two lines that are perpendicular will be opposite reciprocals (that is, multiplying them gets us -1.)B) We can substitute a point inside an incomplete equation to try and find a missing value.So first, let's find the opposite reciprocal of 7 which will be the slope to this equation.
Reciprocal of 7: [tex]\frac{1}{7}[/tex] Opposite of [tex]\frac{1}{7}[/tex]: [tex]-\frac{1}{7}[/tex]So the slope of this line will be [tex]-\frac{1}{7}[/tex]. The y-intercept will change, and we can substitute what we know into the equation [tex]y=mx+b[/tex].
[tex]y = -\frac{1}{7}x+b[/tex]
Now, we can substitute a point on the graph (14, 8) into this equation to find b.
[tex]8 = -\frac{1}{7} \cdot 14 + b[/tex] [tex]8 = -\frac{14}{7} + b[/tex] [tex]8 = -2 + b[/tex] [tex]b = 10[/tex]Now that we know the y-intercept, we can finish off our equation by plugging that in.
[tex]y = -\frac{1}{7}x + 10[/tex]

Answer:
For figure 1:
Area of rectangle = 7x + 21
For figure 2:
Area of rectangle = [tex]\mathbf{p^2-9p }[/tex]
Step-by-step explanation:
We need to find area of rectangle
The formula used is: [tex]Area\:of\:rectangle=Length\times Width[/tex]
For figure 1:
Length = 7
Width = x+3
Putting values in formula and finding area of rectangle
[tex]Area\:of\:rectangle=Length\times Width\\Area\:of\:rectangle=7\times (x+3)\\Now,\: multiply\:7\:with\:terms\;inside\:the\:bracket\\Area\:of\:rectangle=7(x)+7(3)\\Area\:of\:rectangle=7x+21\\[/tex]
So, area of rectangle = 7x + 21
For figure 2:
Length = p
Width = p-9
Putting values in formula and finding area of rectangle
[tex]Area\:of\:rectangle=Length\times Width\\Area\:of\:rectangle=p\times (p-9)\\Now,\: multiply\:p\:with\:terms\;inside\:the\:bracket\\Area\:of\:rectangle=p(p)-p(9)\\Area\:of\:rectangle=p^2-9p\\[/tex]
So, area of rectangle = [tex]\mathbf{p^2-9p }[/tex]

Step-by-step explanation:
In Randy's town all stand alone store front signs must be exactly 8 feet high. When mounted atop a pole , the combined height of the sign and pole must be less than 20 feet or greater than 35 feet so that they dont interfere with the power and phone lines. Write a compound Inequality to represent the possible above ground height of the pole.
Answer:
[tex]x<12[/tex] or [tex]x > 27[/tex]
Step-by-step explanation:
Given
[tex]Lower\ Bound = 20[/tex]
[tex]Upper\ Bound = 35[/tex]
[tex]Height = 8[/tex]
Required
Represent as a compound inequality
Let the pole height be x:
So, the combine height of the pole and the sign is [tex]x + 8[/tex]
The height must be less than 20ft.
So, we have:
[tex]x + 8 < 20[/tex]
Subtract 8 from both sides
[tex]x + 8 - 8 < 20 - 8[/tex]
[tex]x < 20 - 8[/tex]
[tex]x<12[/tex]
or The height must be less than35ft
So, we have:
[tex]x + 8 > 35[/tex]
Subtract 8 from both sides
[tex]x + 8 - 8 > 35 - 8[/tex]
[tex]x > 35 - 8[/tex]
[tex]x > 27[/tex]
So, the compound inequality is:
[tex]x<12[/tex] or [tex]x > 27[/tex]
