Solve the following inequality. Negative one-half p less-than negative 16 Which graph shows the correct solution?
Answer:
p > 10.67
Step-by-step explanation:
Given the inequality -1 1/2p < -16
Before we can represent the inequality on a graph we just simplify it first. On simplification:
-1 1/2p < -16
(-3/2)p < -16
Multiplying both sides by 2
-3p < -32
Dividing both sides by -3 will change the sense of the inequality as shown:
p > -32/-3
p > 32/3
p > 10.67
Find the graph of the resulting inequality in the attachment.

7/2x+1/2x = 18+ 9/2x
Answer:
x=-36
Step-by-step explanation:
Add the 7/2x +1/2x to be 8/2x which means that it'll be 4x=18=9/2
then subtract 9/2x on both sides so itll be
[tex]4x=18+\frac{9}{2} x[/tex]
-9/2x -9/2x
[tex]-\frac{1}{2} x=18[/tex] because if you do 8/2-9/2 it's -1/2
then multiply the reciprocal to both sides so
[tex](\frac{2}{-1})(-\frac{1}{2}x)=(\frac{2}{-1})(18)[/tex]
which then cancels out -1/2 and makes it
x=-36

An exam consists of 4 true/false questions and 6 multiple-choice questions with a, b, c, d, and e as
options. How many different ways could the exam be completed if someone randomly answered the
questions?
Answer:
Step-by-step explanation:
To answer this problem, you break the answer into two parts, one part for the true/false section and another part for the multiple-choice section.
True/False
There are 2 ways to answer each of the 4 true/false questions, T or F.
The number of ways to answer the trur/false section is [tex]2\times2\times2\times2=2^4=16[/tex].
Multiple-Choice
There are 5 ways to answer each question so the number of ways to answer this section is
[tex]5\times5\times5\times5\times5=5^6=15625[/tex]
You can answer the T/F section in 16 ways and the M/C section in 15625 ways, so the entire exam can be answered in
[tex]16\times15625=250000[/tex] ways!
It's mind-boggling that only 1 of those ways gets a score of 100%!
A copy machine makes 19 copies in 3 minutes and 15 seconds. How many copies does it make per minute?
Answer:
6
Step-by-step explanation:
It makes 19 copies in 3 minues and 15 seconds
3 minutes and 15 seconds is 195 seconds
195 ÷ 19 = 10 approximately which means the machine makes 1 copy every 10 seconds and 6 copies per minute
Answer: 5.846 ~ 6copies
Step-by-step explanation:
A copy machine makes 19copies in 3minutes and 15secs
How many copies in per minute
I.e how many copies per minute
Looking at this,
Convert the 3mins 15secs all into mins
I.e convert the 15secs into mins
Remember that 60secs makes 1mins
So 15secs will make x
Cross multiply
15secs ×1= 60secs ×x
X= 15/60
X= 0.25mins
Add to the already 3mins
That makes
=3mins+0.25mins
=3.25mins
Now,
19copies done in 3.25mins
Let the unknown copies be h
19copies in 3.25mins
H copies in 1mins
Cross multiply
H×3.25mins=19×1mins
3.25H=19
H=19/3.25
H= 5.846copies
H=~6copies
So the copying machine makes approximately 6copies per minute

Use the distributive property to simplify the expression 15(14a)
Answer:
[tex]15(14a) = 210a[/tex]
Step-by-step explanation:
We want to simplify the expression 15(14a) using the distributive property.
We rewrite as:
[tex]15(14a) = 15(10a + 4a)[/tex]
According to the distributive property:
[tex]a(b + c) = ab + ac[/tex]
This implies that:
[tex]15(14a) = 15 \times 10a + 15 \times 4a[/tex]
We simplify to obtain:
[tex]15(14a) = 150a + 60a[/tex]
Add on the right to get:
[tex]15(14a) = 210a[/tex]
Principal value of Arccos(-1)

Anastasia thinks of a positive integer.
Barry doubles Anastasia's number.
Connor trebles Barry's number.
Damion multiplies Connor's number by 6.
Eve notices that the total of the four numbers is a perfect square.
What is the smallest positive integer that Anastasia could have thought of?
Answer:
6
Step-by-step explanation:
Anastasia thinks of a positive integer, say x
Barry doubles Anastasia's number.
Barry's Number=2xConnor trebles Barry's number.
Connor's Number=3xDamion multiplies Connor's number by 6.
Damions Number=6(3x)=18xTotal of the Four Numbers=x+2x+3x+18x=24x
To find the value of x that makes 24x the smallest perfect square
First, express it as a product of prime factors
[tex]24x=2 X 2 X 2 X 3 X x=2^3X3Xx\\$Multiply both sides by 2 and 3 to make the powers even\\24 X 2 X 3=2^3X3X2 X 3=2^4X3^2\\$24 X [2 X 3]=144 which is a perfect square\\Therefore, x=6[/tex]
Anastasia's initial number could be denoted as 'a'. This number is modified by Barry, Connor, and Damion, and the sum of all these numbers is a perfect square. The smallest positive integer for 'a' that achieves this is 1.
Explanation:Let's denote the number that Anastasia thought of as 'a'. Barry doubles this number, so his number becomes '2a'. Connor triples Barry's number, so his number becomes '6a'. Damion multiplies Connor's number by 6, so his number becomes '36a'. The total of these four numbers must be a perfect square. So the sum 'a + 2a + 6a + 36a' equals a perfect square. That simplifies to '45a', which is equal to a perfect square.
The smallest positive integer when multiplied by 45 and is a perfect square would be when 'a = 1' as 45 itself is not a perfect square. So, the smallest positive integer that Anastasia could have thought of is 1.

Express z=−10\sqrt{3} −10i in polar form.
Express your answer in exact terms, using radians, where your angle is between 0 and 2π radians, inclusive.
Answer:
z = [20/sqrt(3][cos(-2π/3) + isin(-2π/3)]
Step-by-step explanation:
Polar form is
r(cos(theta) + isin(theta))
r = sqrt[(-10/sqrt3)² + (10)²]
r = sqrt(400/3)
r = 20/sqrt(3)
tan^-1[10 ÷ (10/sqrt(3))] = π/3
Theta: -π + π/3 = -2π/3
z = [20/sqrt(3][cos(-2π/3) + isin(-2π/3)]

k² − 4k +
Answer:
4.
Step-by-step explanation:
Hope this helps!
Answer:
k² − 4k + 4
Step-by-step explanation:
recall the following property of perfect square quadratics
(a-b)² = a²- 2ab + b² --------------( eq1)
We are given:
k² − 4k + ? --------------(eq 2)
and we are asked to determine ? for which the expression above is a perfect square.
Manipulating the given equation:
k² − 4k + ? (factor out 2 from the 2nd term), we get:
k² −(2)(k)(2) + ?
now we compare this with the right side of (eq1)
a²- 2 a b + b²
we can clearly see that a = k and b = 2,
substituting this back into eq 2,
k² − 4k + 2²
= k² − 4k + 4
A shape is randomly selected from the following quadrilaterals: parallelogram, rhombus, rectangle, square, and trapezoid. What is the probability that it has four right angles, given that it has four congruent sides?
Answer:
1/2.
Step-by-step explanation:
There are 2 quadrilaterals which have 4 congruent sides in the list: A square and a rhombus, The square is the one with four right angles.
So the required probability is 1/2.
The probability that the shape has four right angles, given that it has four congruent sides is 1/2.
What is probability?Probability is the ratio that shows the likelihood of an event occurring from a given set of other events.
It is given that there are 5 shapes.
There are 2 shapes that have congruent sides. They are rhombus and square.
There are 2 shapes that have right angles. They are the square and the rectangle.
P( shape has four right angles, given that it has four congruent sides ) = number of shapes with four congruent sides and four right angles/number of shapes with congruent sides = 1/2
Therefore, we have found that the probability that the shape has four right angles, given that it has four congruent sides is 1/2.

what is the area of a triangle whose side is 17 meters long
Answer:
125.141
Step-by-step explanation:
Assuming that this is an equilateral triangle, I am going to divide this triangle in half to get a right triangle.
17 is our hypotenuse
17/2 = 8.5, this is one of our legs
The other leg is our height, which we will find.
We use Pythagoras Theorem to find the height/leg: [tex]a^{2} +b^{2} =c^{2}[/tex]
[tex]17^{2} -8.5^{2} = 216.75[/tex]
[tex]\sqrt{216.75}[/tex] = 14.72243186
Now, we use another formula to find the area of the triangle: [tex]\frac{Base*Height}{2}[/tex]
14.72243186 × 17 = 250.2813416
250.2813416 ÷ 2 = 125.1406708

The perimeter of a rectangular field is 344 yards. If the width of the field is 79 yards, what is it’s length
Answer:
Im not to sure but 93
Step-by-step explanation:
if the width is 79, then 79 plus 79 is 158
and 344 minus 158 is 186
and 186 divided by two is 93
hope that helped :)
Answer:
93 yards
Step-by-step explanation:
When you have a rectanglular field, you can double the width, and then double the length, then add them together to get the perimeter.
If the perimeter is 344, and the width is 79, we can double it to find the value of 2 of the sides, because, if you are on a rectangular field, double the width, then you have to add it to the lengt doubled.
79+79=158
We can subtract 344 by 158 to get the doubled version of the length. After we find the doubled version of the length, we have to divide that by 2.
344-158=186
Now, like I said, we have to divide 186 by 2 to find how much the length is.
186/2=93
The length is 93 yards.
