1. Jose did not make an error. His estimate of $12 is correct.
2. Jose incorrectly rounded $2.85 down to $2. The estimate should be $18.
3. Jose incorrectly rounded 6.2 up to 7.
4. Jose incorrectly multiplied 2 and 7. The estimate should be $14.

Find the perimeter of triangle ABC
Answer:
20 units
Step-by-step explanation:
to solve this equation you need the pythagorean theorem: a^2 + b^2 = c^2
2^2 + 7^2 = 53; square root of 53 is 7.28010989; or about 7.3 units (line AC)
2^2 + 6^2 = 40; square root of 40 is 6.32455532; or about 6.3 units (line BC)
4^2 + 5^2 = 41; square root of 41 is 6.40312424; or about 6.4 units (line AB)
7.3 + 6.3 + 6.4 = 20
20 units

If Tristan wants to stretch the spring by 9 inches, how many kilograms of weight must he apply to it?
Answer:
Step-by-step explanation:
Substitute y = 9 into the equation y = 3x, or locate the answer on the graph:
y = 3x
9 = 3x.
Divide both sides of the equation by 3:
[tex]\frac{9}{3}[/tex] = [tex]\frac{3x}{3}[/tex]
3 = x
The spring stretches 9 inches with 3 kilograms of weight attached to it.

4(x-8)+12 equal 2(2x-9)
(Answer explained)
4(x-8)+12=2(2x-9)
We move all terms to the left:
4(x-8)+12-(2(2x-9))=0
We multiply parentheses
4x-(2(2x-9))-32+12=0
We calculate terms in parentheses: -(2(2x-9)), so:
2(2x-9)
We multiply parentheses
4x-18
Back to the equation:
-(4x-18)
We add all the numbers together, and all the variables
4x-(4x-18)-20=0
We get rid of parentheses
4x-4x+18-20=0
We add all the numbers together, and all the variables
-2!=0
There is no solution for this equation

In an unknown planet, a rock with a mass of 10 kg has a weight of 20 N. What is the gravitational acceleration of objects near the surface of the unknown planet?
Answer:
The gravitational force between a mass and the Earth is the object’s weight. Mass is considered a measure of an object’s inertia, and its weight is the force exerted on the object in a gravitational field. On the surface of the Earth, the two forces are related by the acceleration due to gravity: Fg = mg. Kilograms and slugs are units of mass; newtons and pounds are units of weight.
You can use Newton’s law of gravitation to get the acceleration due to gravity, g, on the surface of the Earth just by knowing the gravitational constant G, the radius of the Earth, and the mass of the Earth. The force on an object of mass m1 near the surface of the Earth is
F = m1g
This force is provided by gravity between the object and the Earth, according to Newton’s gravity formula, and so you can write

Somebody please answer this
Answer:
a=4
Step-by-step explanation:
combine like terms
8a-4=36
add on both sides
8a-4+4=36+4
8a=32
divide
a=32/8
a=4
Answer:
a = 5
Step-by-step explanation:
5a+3a = 8a
8a - 4 = 36
8a - 4 + 4 = 36 + 4
8a = 40
a = 40 divied by 8

The sum of the first 21 terms of the progression, - 18, - 15,-12.....is?
The sum of 21 terms is -1080.
What is Arithmetic Progression?A series in which the differences between each pair of following terms are the same is known as an arithmetic progression.An arithmetic progression is a sequence in which every phrase—aside from the initial term—is created by multiplying the previous term by a predetermined amount.given:
- 18, - 15,-12.....
First term, a= -18
common difference, d= -15 + 18= -3
So, [tex]S_{21[/tex] = 21/2 [ 2(-18)+ (21- 1) (-3)]
[tex]S_{21[/tex] = 21/2 [ -36 + (20) (-3)]
[tex]S_{21[/tex] = 21/2 [ -36 - 60]
[tex]S_{21[/tex] = 21/2 (-96)
[tex]S_{21[/tex] = 21 x (-48)
[tex]S_{21[/tex] = -1008
Hence, the sum of 21 terms is -1080.
