Answer:
try using percent decrease calculator
Step-by-step explanation:
maybe that'll help
Answer:
The answer is 20%
Step-by-step explanation:
5=100%
meaning if you decrease it by one each time it will look like this:
5=100%
4=80%
3=60%
2=40%
1=20%
so if it was decreased to four your answer is 20%
and you still have 80% remaining.
A powerboat heads due northwest at 13 m/s with respect to the water
across a river that flows due north at 5.0 m/s.
What is the velocity (both magnitude and direction) of the motorboat with
respect to the shore?
9514 1404 393
Answer:
16.9 m/s N 32.9° W
Step-by-step explanation:
The resultant magnitude can be found from the law of cosines. The internal angle between the boat's heading and the river flow is 135°, so the magnitude of the boat's net speed is ...
v² = 5² +13² -2·5·13·cos(135°) ≈ 285.924
v = 16.9093 . . . . m/s
The angle (α) between the boat's heading and the resultant velocity can be found from the law of sines.
sin(α)/5 = sin(135°)/16.9093
α = arcsin(5/16.9093×sin(135°)) ≈ 12.07°
The boat's actual heading will be this angle less than the 45° angle the heading makes with due North.
45° -12.07° = 32.93°
The boat's velocity with respect to shore is about ...
16.9 m/s N 32.9° W

what is the correct evaluation of 3x-x+2,when x is equal to -4?
14
-6
6
-14
Answer:
The answer is -6.
Step-by-step explanation:
You have to substitute x = -4 into the expressions :
3x - x + 2
= 3(-4) - (-4) + 2
= -12 + 4 + 2
= -6
if x=3 and x-y= -3

112.212 - (- 3.25)
Answer:
115.462
Step-by-step explanation:
Answer: 115.462
Step-by-step explanation:
To start, the first thing we can observe is two negative signs, which we know turns into a positive sign.
Therefore, we now have:
112.212 + 3.25
115.462

a) Fill in the chart.
b)write and equation for the function.
Answer:
a) there is no chart but we can elaborate one:
taxi fee half-miles driven
$1.75 0
$2.05 1
$2.35 2
$2.65 3
$2.95 4
$3.25 5
$3.55 6
b) y = 0.3x + 1.75
where:
y = taxi fee
x = half miles driven
Could someone please answer this And explain I would really appreciate it thank you so much :)
Answer:
The first choice
Step-by-step explanation:
So you see that square down there, does mean that the angle is 90 degrees. So 90-50 = 40 so yea the first choice.
A) To get the output, subtract 7 from the
input, then divide the result by 3
f(x) = 3x - 7
k(x) = x-7/3
h(x) = x/3 - 7
g(x) = 3(x-7))
Answer:
h(x) = x/3 - 7

Answer:
Emily pays 10.40 and Andy pays 8 dollars
Step-by-step explanation:
So let's start with Emily, she need 21 feet of wire, so we convert this to inches so; [tex]1foot=12inches\\ 21feet=(12inches)*21=252inches[/tex] but it's not listed on the tableSo we try to find the closest approximation to 252 inches which we get by adding 100 inches and 160 inches to get 260 inchesSo Emily will pay the cost of those to lengths so 100 inches cost 4.00 dollars and 160 inches costs 6.40 dollarsso she pays 4.00+6.40=10.40 dollarsNow for Andy we do much the same and find the inches in 11 yards[tex]1 yard=36inches\\ 11yards=(36inches)*11=396inches[/tex] this is also not listedSo we get the closest approximation, which is 4 of the 100 inch wires, so we get 400 inches costing 4*4.00=8 dollarsSeti graphed the point Three-halves and labeled that location P. Which number line shows this point? A number line going from 0 to 2 in increments of 1. There are 2 equals spaces between each number. Point P is half-way between 1 and 2. A number line going from 0 to 2 in increments of 1. There are 3 equal spaces between each number. Point P is on the mark to the left of 1. A number line going from 0 to 2 in increments of 1. There are 2 equals spaces between each number. Point P is half-way between 0 and 1. A number line going from 0 to 2 in increments of 1. There are 3 equal spaces between each number.

What is the length of z? (Round to the nearest tenth)
Answer:
z = 10.8
Step-by-step explanation:
[tex]9^{2} + 6^{2} = c^{2}[/tex]
81 + 36 = [tex]c^{2}[/tex]
117 = [tex]c^{2}[/tex]
c = [tex]\sqrt{117}[/tex]
c = 10.8
c = z
