Answer:
[tex]\sf \dfrac{-1}{2}[/tex]
Step-by-step explanation:
Find the slope:
(-9 , -5) ⇒ x₁ = -9 ; y₁ = -5
(-1 , -9) ⇒ x₂ = -1 ; y₂ = -9
[tex]\sf \boxed{Slope = \dfrac{y_2-y_1}{x_2-x_1}}[/tex]
[tex]\sf = \dfrac{-9-[-5]}{-1-[-9]}\\\\\\=\dfrac{-9+5}{-1+9}\\\\\\=\dfrac{-4}{8}\\\\\\=\dfrac{-1}{2}[/tex]
Answer:
Slope = -1/2
Step-by-step explanation:
Formula we use,
→ (y2 - y1)/(x2 - x1)
Now the value of slope is,
→ (-9 -(-5))/(-1 -(-9))
→ (-9 + 5)/(-1 + 9)
→ -4/8 = -1/2
Hence, the slope is -1/2.
1: A is directly proportional to B.
When A = 12, B = 3
Direc
(a) Find a formula for A in terms of B.
(b) Find the value of A when B = 5
(c) Find the value of B when A= 36
Answer:
a)A=4B
b)A=20
c)B=9
If it is directly proportional it means that A=kB.
you can substitute the numbers to find k.
12=k3
k=4
so the formula is A=kB.
For part b and c it is just substitution

Which one of the following is NOT equivalent to 3/4? 16/24 15/20 6/8 24/32 PWEASE HURRY THESE ARE ALL MY POINTS
Which one of the following is NOT equivalent to 3/4?
16/24 = 2/3
15/20 = 3/4
6/8 = 2/3
24/32 = 3/4
Answer: 16/24 and 24/32 are not equivalent to 3/4
Step-by-step explanation:
Equivalent fractions represent the same value, even though they look different.
Here, when we convert every fraction to its simplest form, we can verify if they are equal.
(16/24) ÷ (8/8) = 2/3
(15/20) ÷ (5/5) = 3/4
(6/8) ÷ (2/2) = 3/4
(24/32) ÷ (4/4) = 6/7
As the simplest forms of 16/24 and 24/32 are not 3/4, they are not equivalent fractions of 3/4.

a rectangular storage area is to be constructed along a side of a building. a security fence is required along the remaining three sides of the area. what is the maximum area that can be enclosed with 703 ft of fencing?
The largest area that may be surrounded by fencing is 61776.13 m².
A building's side will have a rectangular storage room built into it. The remaining three corners of the space need security fencing.
The maximum area is enclosed within 703ft of fencing.
Let x = width
L = length
The perimeter with 3 sides;
L + 2x = 703
L = (703 - 2x)
Let, Area = x * L
Now, replace L with (703 - 2x);
A = x * (703 - 2x)
A = 703x - 2x²
To get the max area by finding the axis of symmetry;
x = -b/2a
In this equation a = -2; b = 703
x = -703 / (2*-2)
x = 175.75m, ( width for the max area )
To get the max area, x=175.75;
A = -2(175.75²) + 703(175.75)
A = -61776.12 + 123552.25
A = 61776.13 m² is a max area
Hence, The maximum area that can be enclosed with 703ft of fencing is 61776.13 m².

Which term is a constant numerical value? I need so much help
- Lyra was trying to determine the slope ratio for the triangle at right, and she
says the answer is 2.675. Isiah claims that cannot be correct. Who is
right? How do you know?
Answer:
Isiah is correct. The slope is about 0.344.
Step-by-step explanation:
Lyra and Isiah want the slope of the hypotenuse in a triangle with an angle of elevation of 19°.
SlopeThe slope is the ratio of "rise" to "run". In a right triangle, that is the ratio "opposite"/"adjacent". This ratio is the tangent of the angle of elevation.
tan(19°) ≈ 0.344
The slope is about 0.344. Isiah is correct.
Isiah knows Lyra is not correct because the slope in a triangle with a 45° angle is 1. Lyra' value of 2.675 is about right for an angle of 69.5°, much greater than either 45° or the given angle of 19°.

Additional comment
Unfortunately, the diagram is not drawn to scale. This is often the case with diagrams in geometry problems. The diagram here is misleading in that it seems to show a slope greater than 1 for a 19° angle.

The toy store created a display of s shelves of remote control cars. Each shelf contains 16 cars. Write an expression that shows how many cars are on the display.
The expression that shows number of remote control cars on the display self is 16s.
Mathematical expressions are formed using at least two numbers, variables, and there must be one arithmetic operation, and a statement. If there are x items are given in one self and there are n number of self and we have to find total number of items in all self, then we have to multiply x by n.
Here, there are 16 remote control cars on a display self. The number of display shelves is s.
So, the total number of cars will be 16 times of s.
Number of cars on display = 16s
Therefore, the expression that shows the number of cars on display is 16s.

Since they are all like terms because they all have y it is pretty easy to solve now! So it would be 4y!

Refer to the figure below. M
The measure of the angle ∠C is 17°.
The angle having a measure equal to 32° and the angle ∠B form a linear pair. They are supplementary angles. When two lines cross, they generate a pair of neighbouring angles called a linear pair. A linear pair's two angles are always supplementary, which means their measurements add up to 180 degrees. The sum must be equal to 180°.
32° + ∠B = 180°
∠B = 180° - 32° = 148°
Now, we will use the angle sum property of a triangle. The sum of all the angles in a triangle is equal to 180°.
∠B + ∠C + 15° = 180°
148° + ∠C + 15° = 180°
∠C + 163° = 180°
∠C = 180° - 163° = 17°

1.92% is the probability .
Describe probability using an example?
By dividing the number of preferable possibilities by the total number of potential outcomes, probability, which measures the likelihood that an event will occur, is obtained. The most basic illustration is a coin toss. There are only two outcomes that can occur when you flip a coin: either heads or tails.The probability of an event is the ratio of the size of the event space to the size of the sample space.
The size of the sample space is the total number of possible outcomes
The event space is the number of outcomes in the event you are interested in.
so
Let
x------> size of the event space
y-----> size of the sample space
so
P = x/y
Find out the probability that the first student selected will be left-handed
we have
x = 6
y = 40
substitute
P = 6/40
Simplify
P = 3/20
the probability that the second student selected will be left-handed
we have
x = 6 - 1 = 4
y = 40 -1 = 39
substitute
P = 5/39
the probability that the 2 students selected will both be left-handed
Multiply the probabilities
P = 3/20(5/39) = 15/780
