Answer:
132-110(the original price)= 22
Step-by-step explanation:
114+18=132
Because you would add 20% to 100% which makes it 120% and then you would solve like any other percent. Thus getting 110 as the original price.

A cyclist rides her bike at a speed of 10 miles per hour. What is this speed in kilometers per hour? How many kilometers will the cyclist travel in 3 hours? In your computations, assume that 1 mile is equal to 1.6 kilometers. Do not round your answers.
Answer:
16 kilometers per hour
48 kilometers
Step-by-step explanation:
10m/ph -> km/hr
since 1 mile is equal to 1.6 kilometers, we use this to convert.
10miles x 1.6 kilometers
10 x 1.6 = 16
so, the answer is 16 kilometers per hour
To find out how many kilometers they travel in three hours, we multiply our last answer times three.
16 x 3 = 48
48 kilometers
This is because the cyclist is traveling at 16 kilometers per hour so we multiply it by the three hours in the question.
A 70-inch pipe is cut into two pieces, One piece is four times the length of the other. Find the length of
the shorter piece
Answer: 14 inches
Step-by-step explanation:
If one is 4 times the length of the other, then you'll have to divide by 5 because that's how many times there are in total. So 70/5 would be 14 which is the length of the smaller one. 70-14= 56 which is the length of the normal one.
Lily begins solving the equation 4(x-1-x=3(x+5)-11. Her work is shown below.
4(x-1)-x=3(x+5)-11
4x-4-x=3x+15-11
3x-4=3x+4
How can her partial solution be interpreted?
• The equation has one solution: x=0
•The equation has one solution: x=8
•The equation has no solution.
•The equation has infinite solutions.
Answer:4
Step-by-step explanation:
Answer:
The equation has no solution
Step-by-step explanation:
First you can 3x-4 = 3x+4
+4 +4
You would then get 3x = 3x + 8
Then you would do 3x = 3x + 8
-3x -3x
Which gets you 0=8 which you know is impossible because zero eqauls zero not 8
In conclusion, the answer is the equation has no solutions

The city of Paris, France is completely contained within an almost circular road that goes around the edge. Use the map with its scale to estimate the circumference and area of Paris.
Use 3.14 to estimate π and round your answer to the nearest whole number.
a. The circumference of Paris is about ______ MIles
b. The circumference of Paris is about ______ mi2
Complete Question:
The city of Paris, France is completely contained within an almost circular road that goes around the edge. The radius is 3 miles. Use the map with its scale to estimate the circumference and area of Paris.
(See attachment for map)
Answer:
[tex]C = 18.84\ miles[/tex]
[tex]A = 28.26\ miles^2[/tex]
Step-by-step explanation:
Given
[tex]Radius = 3\ miles[/tex]
Solving (a): Circumference
Circumference (C) is calculated as thus:
[tex]C = 2\pi r[/tex]
Where
[tex]r = radius = 3[/tex]
and
[tex]\pi = 3.14[/tex]
So:
[tex]C = 2 * 3.14 * 3[/tex]
[tex]C = 18.84\ miles[/tex]
Hence, the circumference is about 18.84 miles
Solving (b): Area
Area (A) is calculated as thus:
[tex]A = \pi r^2[/tex]
Where
[tex]r = radius = 3[/tex]
and
[tex]\pi = 3.14[/tex]
[tex]A = 3.14 * 3^2[/tex]
[tex]A = 3.14 * 9[/tex]
[tex]A = 28.26\ miles^2[/tex]
Hence, the area is about 28.26 mi²
Circumference and Area of Paris is 18.84 mile and 28.26 miles²
Given that;According to map
Radius of Paris = 3 miles
Find:Circumference of Paris = 2πr
Area of Paris = πr²
Circumference of Paris in miles = 2(3.14)(3)
Circumference of Paris in miles = 18.84 miles
Area of Paris = πr²
Area of Paris = (3.14)(3)²
Area of Paris = (3.14)(9)
Area of Paris = 28.26 miles²

Yesterday, 170 guests at a hotel called for room service out of 425 guest. What percentage of the guests at the hotel called for room service yesterday?
Answer: 40%
Step-by-step explanation: to put it simply if you are using a calculator, enter 170÷425×100 which will give you 40 as the answer.
if you want an explanation here:
170 of 425 can be written as:
170/425.
To find percentage, we need to find an equivalent fraction with denominator 100. Multiply both numerator & denominator by 100
170/425
×
100/100
(170 × 100/425) x 1/100
=
40/100
Therefore, the answer is 40%

Step-by-step explanation:
Since the ray AE is an angle bisector, it means that it cuts the angle 50 / 50, or perfectly in half.
This means that angle BAE and angle EAC are actually congruent
∠BAE = ∠EAC
[tex]x + 30 = 3x - 10[/tex]
Get rid of x on one side. Since you are solving for x, use the more simple x
This becomes this ⇅

Subtract 10 from both sides
20 = 2x
20 divided by two
2x divided by two
x = 10
2x-y and 7y= -7 +3x solve by substitution
Answer:
x = -7/11, y = -14/11
Step-by-step explanation:
2x = y ------- (1)
7y = -7+3x -------- (2)
from (1)
2x = y
y = 2x ------- (3)
substitute (3) into (2)
7y = -7+3x
7(2x) = -7+3x
14x = -7+3x
14x-3x = -7
11x = -7
x = -7/11
substitute x = -7/11 into (3)
y = 2x
y = 2(-7/11)
y = -14/11
x = -7/11, y = -14/11

A particle moves on the hyperbola xy=18 for time t≥0 seconds. At a certain instant, y=6 and dydt=8. What is x that this instant?
Answer:
The value of x at this instant is 3.
Step-by-step explanation:
Let [tex]x\cdot y = 18[/tex], we get an additional equation by implicit differentiation:
[tex]x\cdot \frac{dy}{dt}+y\cdot \frac{dx}{dt} = 0[/tex] (1)
From the first equation we find that:
[tex]x = \frac{18}{y}[/tex] (2)
By applying (2) in (1), we get the resulting expression:
[tex]\frac{18}{y}\cdot \frac{dy}{dt}+y\cdot \frac{dx}{dt} = 0[/tex] (3)
[tex]y\cdot \frac{dx}{dt}=-\frac{18}{y}\cdot \frac{dy}{dt}[/tex]
[tex]\frac{dx}{dt} = -\frac{18}{y^{2}} \cdot \frac{dy}{dt}[/tex]
If we know that [tex]y = 6[/tex] and [tex]\frac{dy}{dt} = 8[/tex], then the first derivative of x in time is:
[tex]\frac{dx}{dt} = -\frac{18}{6^{2}} \cdot (8)[/tex]
[tex]\frac{dx}{dt} = -4[/tex]
From (1) we determine the value of x at this instant:
[tex]x\cdot \frac{dy}{dt} = -y\cdot \frac{dx}{dt}[/tex]
[tex]x = -y\cdot \left(\frac{\frac{dx}{dt} }{\frac{dy}{dt} } \right)[/tex]
[tex]x = -6\cdot \left(\frac{-4}{8} \right)[/tex]
[tex]x = 3[/tex]
The value of x at this instant is 3.
The value of [tex]x[/tex] at the instant when particle moves on the hyperbola [tex]xy=18[/tex] from time [tex]t\geq 0\;\rm seconds[/tex] is [tex]3[/tex].
Differentiating the given equation [tex]xy=18[/tex] with respect to the [tex]'t'[/tex] to get an addition equation by implicit differentiation,
[tex]x\dfrac{dy}{dt}+y\dfrac{dx}{dt}=0----(i)[/tex]
Also, from the given equation, we can write [tex]x=\dfrac{18}{y}[/tex]
Substitute the value of [tex]x[/tex] in the equation (i), we get
[tex]\begin{aligned}\dfrac{18}{y}\dfrac{dy}{dt}+y\dfrac{dx}{dt}&=0\\\dfrac{dx}{dt}&=-\dfrac{-18}{y^2}\dfrac{dy}{dt}\end{aligned}[/tex]
Substitute the value of [tex]y=6[/tex] and [tex]\dfrac{dy}{dt}=8[/tex] in the above equation, we get
[tex]\begin{aligned}\dfrac{dx}{dt}&=-\dfrac{-18}{y^2}\dfrac{dy}{dt}\\&=\dfrac{-18}{6^2}\times 8\\&=-4\end{aligned}[/tex]
Now, from equation (i), we can re-write the expression to evaluate the value of [tex]x[/tex] at that instant as-
[tex]x=-y\dfrac{\frac{dx}{dt}}{\frac{dy}{dt}}\\x=-6(\dfrac{-4}{8})\\x=3[/tex]
Hence, the value of [tex]x[/tex] at the instant when particle moves on the hyperbola [tex]xy=18[/tex] from time [tex]t\geq 0\;\rm seconds[/tex] is [tex]3[/tex].

Answer:

20:10
Step-by-step explanation:
for every 2 hydrogen there is 1 oxygen.
20:10 for part 2 can be reduced down to 2:1 because there is still 2 hydrogen for every 1 oxygen
Answer:
A. the ratio would be H2 over 1O
B. the ratio would be 10o over 20h
Step-by-step explanation:
A. Because the water molecule is made of 2 Hydrogen and 1 Oxegen, then you would just put 2/1 or if she or he would like you to be more specific, 2h/ 1o.
B. For this one you would multiply by the 2/1 10 and put the denominator where the numerator is and the original numerator where the denominator used to be. Your answer would then be 10/20. Now you can simplify this ratio by splitting it in half and having it be 5/10 or better yet, 1/2.
I really hope this helps and if you need more explaining please let me know.

If we assume the number of potatoes is proportional to the weight, then we can write the equation ...
n/10 = 10/3.2
n = 100/3.2 = 31.25 . . . . . . . multiply by 10

If 4% of a number is 12, find 2% of that number.
Answer:
6
Step-by-step explanation:
4% = 12
1% = 12/4
2%= 2 x (12/4) = 6
Answer:
2% of the number is 6
Step-by-step explanation:
4% of a number is 12
We want to know what 2% percent of it is.
So if we divide the number 12 by 2 we will be able to find the answer.
Note: 4%/2 = 2%(which is the percent we are looking for) Which is why if we also divide 12 by 2 which is 12/2 we will get 2% of the number.
12/2=6
