Answer:
It's of science not of mathematics
Answer:
[tex] \boxed{ \bold{ \huge{ \boxed{ \sf{10 \: N}}}}}[/tex]
Step-by-step explanation:
Given,
Load distance ( LD ) = 2m
Load ( L ) = 800 N
Effort distance ( ED ) = 160 m
Effort ( E ) = ?
Finding the Effort applied
Apply the principal of simple machine :
[tex] \boxed{ \sf{L \times LD = E\times ED}}[/tex]
[tex] \longrightarrow{ \sf{800 \times 2 = E \times 160}}[/tex]
[tex] \longrightarrow{ \sf{1600 = 160 \: E}}[/tex]
[tex] \longrightarrow{ \sf{160E = 1600}}[/tex]
[tex] \longrightarrow{ \sf{ \frac{160E}{160} = \frac{1600}{160} }}[/tex]
[tex] \longrightarrow{ \sf{E = 10 \: \: newton}}[/tex]
Effort applied = 10 N
Hope I helped!

Question one, how do you solve this? "A, B, and C are collinear. Find AC if AB = 12 and BC = 8"
Question two, can anyone solve these two problems i attached? They use Segment Addition and Angle Addition Postulates.
Answer:
20''Step-by-step explanation:
If points A, B and C are collinear, then A, B and C lies on the same straight line. Hence AB+BC = AC
Given
AB = 12''
BC = 8''
To get length od segment AC, we will substitute the given values into the formula above as shown;
AB+BC = AC
12 + 8 =AC
AC = 12+ 8
AC = 20''
Hence the length of AC is 20''

Answer: The answer to the first question is C. The answer to the second question is A.
the first one is C and the second is A
Two cars, which are 210 miles apart, drive towards
each other at constant speeds. The speed of the
second car is 20 miles per hour faster than the first car.The cars pass each other in 1 1/2 hours. What is the speed of both cars?
Answer:
slower car=60 miles/hr
faster car =80 miles/hr
Step-by-step explanation:
the speed of slower car =x
the speed of faster car=x+20
they both 210 miles apart
(x+x+20)*(1 1/2 )=210
(2x+20)(3/2)=210
3x+30=210
3x=210-30
3x=180
x=180/3 ⇒ x=60
x+20 ⇒ 60+20=80

You buy one shirt for $22 and two pairs of shorts. Your total cost is $56. Assuming both pairs of shorts cost the same amount, what is the price of one pair of shorts? What is the correct equation and solution for this problem? A. 2 x - $22 = $56; x = $34 B. 2 x + $22 = $56; x = $34 C. 2 x + $22 = $56; x = $17 D. 2 x - $22 = $56; x = $17
Answer:
B. 2x + $22 = $56 ; x = $17
Step-by-step explanation:
Assuming a pair of short is accounted for by the variable x.
Your total cost is $56. This means that your expression will equal 56:
________________ = 56
Next, you buy 1 shirt (denoted by s) for $22.
s = $22
You buy 2 pairs of pants. The cost is not given, so it can vary. Give it a variable. The answers denote it as x. As you are buying two pairs of pants, multiply 2 with x:
2 * x = 2x.
Combine the terms and plug it into the equation:
2x + 22 = 56
Next, solve for x. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS. Remember, PEMDAS is the order of operation, &
PEMDAS =
Parenthesis
Exponents & Roots
Multiplication
Division
Addition
Subtraction
First subtract 22 from both sides:
2x + 22 (-22) = 56 (-22)
2x = 56 - 22
2x = 34
Next, divide 2 from both sides:
(2x)/2 = (34)/2
x = 34/2
x = $17
B. 2x + $22 = $56 ; x = $17 is your answer.

Answer:
B. 2x + $22 = $56 ; x = $17

Suppose you charge $4.50/h for baby-sitting. How much will you earn baby-sitting for 3 1/2 hours?
Answer:
You will earn $15.75, $13.50, or $18 depending on how you are getting paid
Step-by-step explanation:
If you are getting paid a flat rate not by the hour, then simply multiply $3.50 by 3.5 to get $15.75
If you are getting paid by the hour, and only by full hours, the you get $3.50 for the first, second, and third hour, but not for the fourth hour because it has only been a half hour, so only $13.50.
If you are getting paid for each hour that you start, then you get $3.50 for four hours, or $18.00 total

The first term of an arithmetic sequence is -2. The eighth term of the sequence is 26. What is the common difference of the arithmetic sequence?
Answer:
d = 4
Step-by-step explanation:
The n th term of an arithmetic sequence is
[tex]a_{n}[/tex] = a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Given a₁ = - 2 and a₈ = 26 , then
- 2 + 7d = 26 ( add 2 to both sides (
7d = 28 ( divide both sides by 7 )
d = 4
Answer:
d = 4
Step-by-step explanation:
a₁ = -2
a₈ = aₙ = 26
n = 8
aₙ = a₁ + d(n-1)
d = aₙ - a₁ / (n-1)
d = 26 -(-2) / (8-1)
d = 26 + 2 / 7
d = 28 / 7
d = 4
-2
-2 + 4 = 2
2 + 4 = 6
6 + 4 = 10
10 + 4 = 14
14 + 4 = 18
18 + 4 = 22
22 + 4 = 26
At the start of summer Ben has $250. He takes summer job
and saves $ 150 per week. Tim has $ 1,650 at the start of
summer, he travels and spends $ 200 per week. At the end of
which week do Ben and Tim have the same amount of money ?
Answer:
week 4
Step-by-step explanation:
With Ben saving up $150 every week, he'll have $850 by week 4 because, $150 times 4 is $600, plus the $250 that he started with equals $850. Tim will also have $850 by week 4 because $200 times 4 equals $800. $800 minus the $1650 that he started off with equals $850.

Whose do you agree with, and why?
Answer:
Kyra is correct.
Step-by-step explanation:
Rational numbers;
All numbers which can be written in the form of [tex]\frac{p}{q}[/tex] are rational numbers.
Example: 1, 2, [tex]\frac{1}{2}[/tex], 1.414141....
Irrational numbers:
Numbers which are not in the form of [tex]\frac{p}{q}[/tex] are irrational.
Example: 1.234, π, √2
So rational and irrational numbers are two separate things.
But all positive and negative numbers are real numbers.
Real numbers may be rational or irrational both.
Therefore, Kyra's interpretation is correct.

Kamal and Anand each Lent the same sum of money for 2 years at 5 percent at simple interest and compound interest respectively. Anand received RS.15 more than Kamal.Find the amount of money lent by each and interest received
Answer:
amount lent: ₹6000interest received: Kamal, ₹600; Anand, ₹615.Step-by-step explanation:
For principal P invested at simple interest rate r, the returned value in t years is ...
A = P(1 +rt)
If K is Kamal's returned value, the given numbers tell us ...
K = P(1 +0.05·2) = 1.1P
__
For principal P invested at compound interest rate r, with interest compounded annually for t years, the returned value is ...
A = P(1 +r)^t
If A is Anand's returned value, the given numbers tell us ...
A = P(1.05)² = 1.1025P
This latter amount is RS.15 more than the former one, so we have ...
1.1025P = 1.1P +15
0.0025P = 15 . . . . . . . . subtract 1.1P
P = 6000 . . . . . . . . . . . divide by 0.0025 . . . . the amount lent
Kamal received 1.1P -P = 0.1P = 600 on the investment.
Each lent ₹6000. Kamal received ₹600 in interest; Anand received ₹615 in interest.

Step-by-step explanation:
[tex]\begin{bmatrix}-8x+y=-32\\ -3x-10=y\end{bmatrix}\\\\\mathrm{Isolate}\:x\:\mathrm{for}\:-8x+y=-32:\quad x=-\frac{-32-y}{8}\\\\\mathrm{Subsititute\:}x=-\frac{-32-y}{8}\\\begin{bmatrix}-3\left(-\frac{-32-y}{8}\right)-10=y\end{bmatrix}\\\\Simplify\\\begin{bmatrix}\frac{3\left(-32-y\right)}{8}-10=y\end{bmatrix}\\\\\mathrm{Isolate}\:y\:\mathrm{for}\:\frac{3\left(-32-y\right)}{8}-10=y:\quad y=-16\\\\\mathrm{For\:}x=-\frac{-32-y}{8}\\\\\mathrm{Subsititute\:}y=-16\\x=-\frac{-32-\left(-16\right)}{8}\\[/tex]
[tex]-\frac{-32-\left(-16\right)}{8}=2\\x=2\\x=2,\:y=-16[/tex]
Answer:
x = 2
y = -16
Step-by-step explanation:
Substitute value of y, -3x - 10 in the equation-8x + y = -32
-8x + (-3x - 10) = -32
-8x - 3x - 10 = -32
-11x - 10 = -32
-11x = -32 + 10
-11x = -22
Divide both sides by coefficient of x which is -11
x = 2
Substitute value of x, 2, in the equation-3x - 10 = y
(-3)2 - 10 = y
-6 - 10 = y
y = -16

Zero is not classified as a D. Natural number
Zero can be quite complicated to place when it comes to numbers but it is generally agreed that zero is:
a whole number and is the smallest one an integer because it is a whole number a rational number because it is an integerThere is however some contention about whether zero is a natural number but most mathematicians have conclusively stated that zero is not a natural number.

What is the slope of the line that passes through (-5,4) and (-1,8)
Answer:
1
Step-by-step explanation:
We can use the slope formula
m = (y2-y1)/(x2-x1)
= ( 8-4)/( -1 --5)
= 4/( -1+5)
= 4/4
=1
You need the slope, so start with the slope formula.
slope = y₂ - y₁ / x₂ - x₁
Substitute (-5, 4) for (x₁, y₁) and (-1, 8) for (x₂, y₂).
So we have 8 - 4 / -1 - -5.
Simplify to find the answer.
So we have 4/4 which is 1.
