Answer:
5th term of AP = -33x - 17
Step-by-step explanation:
Given:
Arithmetic sequences;
[-5x - 5], [-12x - 8], [ - 19x - 11] , ...
Find:
5th term of AP
Computation:
First term a = [-5x - 5]
Common difference d = a2 - a1
Common difference d = [-12x - 8] - [-5x - 5]
Common difference d = -12x - 8 + 5x + 5
Common difference d = -7x -3
5th term of AP = a + [n-1]d
5th term of AP = [-5x - 5] + [5-1][-7x -3]
5th term of AP = [-5x - 5] + [4][-7x -3]
5th term of AP = [-5x - 5] -28x -12
5th term of AP = -5x - 5 -28x -12
5th term of AP = -33x - 17
why do we need to know the different abbreviation of measurements and its equivalent?
Answer:
See explanation.
Step-by-step explanation:
You will need to know the abbreviations of measurements because when pertaining to the real world, an you will see things as so "This fence is about 15ft tall." or "Jacobb is 72in tall." If you do not understand the abbreviations you will not understand what anyone is ever talking about when it comes to measurements. As for knowing how to convert measures to be equivalent, that is important because some measurements are bigger than others. It doesn't make since to say 12 inches, when you can just say 1 foot.
There are 56 sheep in a paddock. Each sheep is either black or white. There are 6 times as many white sheep than black sheep. How many black sheep are there?
Here we want to make a system of equations and solve it, in this way, we will see that there are 8 black sheep.
first, let's define the variables:
x = number of black sheep
y = number of white sheep.
We know that:
"there are 56 sheep"
Then we can write:
[tex]x + y = 56[/tex]
We also know that there are 6 times as many white sheep than black sheep, this means that:
[tex]y = 6 \cdot x[/tex]
Then we have a system of equations:
[tex]x + y = 56[/tex]
[tex]y = 6\cdot x[/tex]
To solve this we need to start by isolating one of the variables in one of the equations. Here, we can see that the variable y is already isolated in the second equation, so we can use that.
Now we can replace that variable in the other equation:
[tex]x + y = 56[/tex]
[tex]x + 6\cdot x = 56[/tex]
Now we can solve this for x, the number of black sheep:
[tex]7\cdot x = 56\\\\x = 56/7 = 8[/tex]
There are 8 black sheep.

100 points i just need helpp
Answer:
5sqrt(5) = q
-5sqrt(5) = q
Step-by-step explanation:
f(q) = q^2 -125
To find the roots set the equation equal to zero
0 = q^2 -125
Add 125 to each side
125 = q^2 -125+125
125 = q^2
Take the square root of each side
±sqrt(125) = sqrt(q^2)
±sqrt( 5*25) = q
±sqrt( 25)* sqrt(5) = q
±5* sqrt(5) = q
±5sqrt(5) = q

The table below shows the base and height of three triangles in centimeters. Which triangles have the same area?
= 1/2 ℎ
Answer:
Triangle 1 and triangle 3 have same area.
Step-by-step explanation:
Given:
Triangle Base Height
1 30 16
2 60 40
3 20 24
Find:
Same area triangle
Computation:
Area of triangle = (1/2)(b)(h)
Area of triangle 1 = (1/2)(30)(16)
Area of triangle 1 = 240 unit²
Area of triangle 2 = (1/2)(60)(40)
Area of triangle 2 = 1200 unit²
Area of triangle 3 = (1/2)(20)(24)
Area of triangle 3 = 240 unit²
So,
Triangle 1 and triangle 3 have same area.

If a•b=b, what must the value of a be?
Answer: I think f
Step-by-step explanation:
The value of a must be 1 in order for the equation to hold true .
If a * b = b, we can find the value of a by isolating it on one side of the equation .
Given that a * b = b, we can divide both sides of the equation by b :
( a * b ) / b = b / b
This equation simplifies to form :
a = 1
For a = 1 the equation is true .
Therefore, the value of a must be 1 in order for the equation to hold true .

Can someone help? I hate math so much lol I don’t understand
Answer:
±6
Step-by-step explanation:
Given the mathematical expression;
√36 < √42 < √49
But, √36 = 6 * 6 = 6²
√49 = 7 * 7 = 7²
Simplifying further, we would substitute the new values respectively;
±[6] < √42 < ±[7]
Therefore, evaluating √36 is equal to ±6.

Given average of 3 numbers = 17 Total of 3 numbers = 17×3 = 51. Given average of 2 numbers = 16 Total of 2 numbers = 16×2 = 32 Therefore, Third Number = 51–32 = 19
Use the Pythagorean Theorem to find the length of the leg in the triangle below. The figure shows a right triangle with one leg marked 3. The hypotenuse is marked 5.
9514 1404 393
Answer:
4
Step-by-step explanation:
If the unknown leg is represented by x, then the Pythagorean theorem tells you ...
x² + 3² = 5²
The sum of the squares of the legs equals the square of the hypotenuse.
Solving for x, we have ...
x² = 5² -3² = 25 -9 = 16
x = √16 = 4 . . . . . . . only the positive root is of interest
The missing leg length is 4 units.

This exercise shows you that the triple (3, 4, 5) will form a right triangle. It is the smallest integer "Pythagorean triple", and the only one that is an arithmetic sequence (the differences between the numbers are the same). You will see this a lot, sometimes multiplied by various factors: 6, 8, 10, for example. It is worth remembering.
Answer:
4
Step-by-step explanation:
Correct answers:
$4$
Let a represent the length of the leg and label a on the figure.
The figure shows a right triangle with legs marked a and 3. The hypotenuse is marked 5.
The figure shows a right triangle with legs marked a and 3. The hypotenuse is marked 5.
Using the Pythagorean Theorem with b=3, c=5, and solving for a, we have
