Weight is a measure of force affected by gravity. The Moon's
gravity is less than Earth's gravity, so objects weigh less on
the Moon than on Earth.

a cat will weigh on the Moon? Explain your reasoning.
Tell it step by step
I think I need to know what the cat weighs first...

A cylinder has a volume of 33,912 units3 and a
height of 12 units. What is the diameter of the
cylinder?
I’ll do 50 points please answer right away !!!!!!!
Answer:
60
Step-by-step explanation:
I hope this helps
The diameter of the cylinder is equal to 59.98 units.
Given the following data:
Volume of cylinder = 33,912 [tex]unit^3[/tex]Height of cylinder = 12 units.To determine the diameter of the cylinder:
First of all, we would find the radius of the circular base of this cylinder.
Mathematically, the volume of a cylinder is given by the formula:
[tex]Volume = \pi r^2h[/tex]
Making r the subject of formula, we have:
[tex]r=\sqrt{\frac{V}{\pi h} }[/tex]
Substituting the given parameters into the formula, we have;
[tex]r=\sqrt{\frac{33912}{3.142 \times 12} }\\\\r=\sqrt{899.43}[/tex]
Radius, r = 29.99 units.
For the diameter:
[tex]Diameter = 2 \times radius\\\\Diameter = 2 \times29.99[/tex]
Diameter = 59.98 units.

In the figure, parallelogram PQSR and Triangle PQT are standing
on the same base and between, the same parallel lines. The
area of triangle PQT is 50 cm?. Find the area of Triangle PRS.
Answer:
50 cm²
Step-by-step explanation:
We know that PQRS is a paralleogram so we know that RS = PQ.
We also know that ΔPQT and ΔPRS has the same height . The the area is the same, from the area of that we can get 50 cm²

14) When simplified, -2(x + 1) - 4(x - 3) is equivalent to
Answer:
-6x+10
Step-by-step explanation:
-2(x + 1) - 4(x - 3)
Distribute
-2x-2 -4x+12
Combine like terms
-6x+10
Answer:
-6x +10
Step-by-step explanation:
First, open the parenthesis by multiplying the number outside to the terms inside:
-2(x+1) = -2x - 2
-4(x-3) = -4x + 12
then combine the like terms:
-2x - 4x + 12 - 2 = -6x + 10
Please help me with this homework
Step-by-step explanation:
we see f(x), which is |x|.
and we see g(x), which is clearly the same basic graph, it is just shifted 3 units down in y direction.
shifts are simply done by keeping the original function definition and then add it subtract a certain constant that then adapts every original functional value.
so, a shift down by 3 units is done by adding -3.
therefore, C is the correct answer (the original f(x) - 3).
Choose the two expressions that are equivalent to 6.5 ÷ 1.3.
A 65 ÷ 13
B 65 ÷ 130
C 650 ÷ 130
D 650 ÷ 13
Answer:
A & C
Step-by-step explanation:
To find the two expressions that are equivalent to 6.5 ÷ 1.3, you need to solve all of them until you get the two expressions that have a quotient of 5.
Let's begin solving!
65 ÷ 13 = 5
So now we know that A is one of our answers
65 ÷ 130 = 0.5
Not one of our answers because the quotient is not 5
650 ÷ 130 = 5
This is our other answer! We don't need to solve D because we only needed to find two expressions which are A and C.
Hope this helps you :)
Answers are A and C.
6.5 ÷1.3 = 5
A. 65 ÷ 13 = 5 so yes
B. 65 ÷ 130 = .5 so no
C. 650 ÷ 130 = 5 so yes
D. 650 ÷ 13 = 50 so no

Step-by-step explanation:
The question is asking what is ∠ABD, you have to look at when A=0 on the projector, so if you follow along the 0° from A, when it reaches D, the project reads 100°
no guessing here,
you know 80° cannot be correct because this angel is obtuse and not acute
which means greater that 90°

24 marbles were shared equally amongst a group of children. each child received 4 Marbles how many children were in the group?
Answer:
6
Step-by-step explanation:
24/6=4
6x4=24
6+6=12
6+6=12 12+12=24
Solution:
Given,
No. of marbles =24
No. of marbles each child received=4
No. of children in the group=?
Here,
No. of children in the group = No. of marbles/
No. of marbles
each child received
=24/4
=6
Hence, There were 6 children in the group.
The equation for line A is given by y= -3/4x-2. Suppose line A is parallel to line B, and line T is perpendicular to line A. Point (2,5) lies on both line B and line T. What is the equation for line B?
Answer:
y=4/3x+19/3
Step-by-step explanation:
perpendicular = slope is the negative reciprical.
plug in the point (-4,1) for (x,y)
1(y)=4/3(-4)+b
1=-16/3+b
b=19/3

Answer:
10.25
Step-by-step explanation:
Using the pythagorean theorem
13^2 = 8^2 + (ML)^2
169 = 64 + (ML)^2
Subtract 64 from both sides
105 = (ML)^2
Take the square root of both sides
10.25 = ML

find three positive consecutive integers such that the product of the smallest and the largest is 26 more than six times the middle integer
Answer:
8, 9, 10
Step-by-step explanation:
three positive consecutive integers
x, x + 1, x + 2
the product of the smallest and the largest is 26 more than six times the middle integer
x(x + 2) = 6(x + 1) + 26
Expand
x^2 + 2x = 6x + 6 + 26
Combine like terms
x^2 + 2x = 6x + 32
Subtract 6x + 32 from both sides
x^2 - 4x - 32 = 0
Factor
(Alternately use the quadratic formula or complete the sqaure)
(x - 8)(x + 4)
x = {-4, 8}
-4 is extraneous because the integers must be positive
x = 8
x + 1 = 9
x + 2 = 10
8, 9, 10
Answer:
[tex]8,9,10[/tex]
Step-by-step explanation:
We can make this an equation and use the variable n to represent our numbers
[tex]n-1(smallest)[/tex]
[tex]n(middle)[/tex]
[tex]n+1(largest)[/tex]
[tex](n-1)\cdot (n+1)=6n+26[/tex]
[tex]n^2-1 = 6n+26[/tex]
[tex]n^2 - 6n - 27 = 0[/tex]
After we factorize we get
[tex]n=9[/tex]
since our smallest is [tex]n-1[/tex] so our smallest number is [tex]8[/tex] and largest is [tex]10[/tex]
