Answer:
n =[tex]\frac{5}{10}[/tex]
Step-by-step explanation:
Answer:
n= 2 and two thirds
Step-by-step:
this is the equation
3/10n=4/5
so to get n by itself, you multiply both sides by 10/3. I did 4/5 times 10/3 and I got 2/2/3, or two and two thirds

Answer:
for #1 it's 1, 4, 5, 6
for #2 it's both lines have the same slope
for #3 it's both lines have a different y-intercept
Step-by-step explanation:
#1 explanation: all of them have the y-intercept of -8
ex. y = 3x (- 8) y = 5x (-8) y = 2x (-8) y = (1/3)x (-8)
#2 explanation: both have a slope of (1/4)
#3 explanation: y = (1/4)x there is not y-intercept that we know of and y = (1/4)x - 5 the y-intercept is at -5 therefore the y-intercepts are different
Definition and description of gravity
Answer:
1. the force that attracts a body toward the center of the earth, or toward any other physical body having mass.
2. extreme or alarming importance; seriousness.
"crimes of the utmost gravity"
Step-by-step explanation:
Gravity, also called gravitation, in mechanics, the universal force of attraction acting between all matter. ... On Earth all bodies have a weight, or downward force of gravity, proportional to their mass, which Earth's mass exerts on them. Gravity is measured by the acceleration that it gives to freely falling objects.

Answer:
[tex]x=4[/tex], [tex]y=61[/tex]
Step-by-step explanation:
Since the triangles are congruent, we already know that they have the same angles and sides.
We can solve for the missing side with this equation:
[tex]51=12x+3[/tex]
subtract [tex]3[/tex] from both sides
[tex]48=12x[/tex]
divide both sides by [tex]12[/tex]
[tex]x = 4[/tex]
Due to the Angle Theorems we already know [tex]2[/tex] of the angles on the triangle:
[tex]63[/tex] and [tex]56[/tex]
We can solve for the missing angle with this equation:
[tex]A+B+C=180[/tex]
[tex]63+56+y=180[/tex]
[tex]119+y=180[/tex]
subtract [tex]119[/tex] from both sides
[tex]y=61[/tex]

A cyclist travels at an average speed of 20 km/h over a distance of 40 km.
How many hours does it take him?
Answer:
Given that speed(v) = 20km/h and time(t) = 50 min
We have to find distance (d)
First convert speed into m/s
v = (20*1000m)/(1*3600s)
v = (50/9) m/s
Now convert time into second
t = 50*60 = 3000 sec
As we know that
d = v*t = (50/9)*3000 = 50000/3
d = 16666.67m or 16.67km
Ans: 16666.67m or 16.67km

find the measure of angle b. no fake answers.
Answer:
∠ b = 42°
Step-by-step explanation:
b and 48° form a right angle, then
b = 90° - 48° = 42°
Answer:
42 degrees
Step-by-step explanation:
The angle shared by 48 and b is 90 total degrees.
Subtract 48 from 90 to find the measure of b
PLEASE HELP, find the orthocenter of this triangle
Answer:
The orthocenter of a triangle is the point at which the three altitudes of a triangle intersect. This involves creating 3 lines, one from each vertex (K, L, and M) perpendicular to the line segment opposite it, so K⊥LM, L⊥KM, and M⊥KL.
Because these three lines intersect at one point, you only need to do this procedure for two of the three altitudes. Because K and M are on the same Y coordinate (-4), lets do this for LM and KL
First, we need to find the slope of the perpendicular to each line segment, so we need the slope of LM and KL.
The slope is the change in Y over the change in X
Slope LM = 6 -(-4) / 2-7 = 10/-5 = -2
Slope KL = -4-(6) / 4-2 = -10/2 = -5
The slope of a perpendicular line is the negative reciprocal of the slope of the given line, so for
the slope of K⊥LM has to be 1/2 and
the slope of M⊥KL has to be 1/5
Second, the vertex has to be on a line with that slope. So using the point-slope formula
(y-y1) = m(x-x1) , where x1,y1 is a point on the line for each line gives us
K⊥LM: y-(-4) = 1/2(x-4)
M⊥KL: y-(-4) = 1/5(x-7)
Third, find the point on both lines, are where the two equations are equal
So, 1/2(x)-2 = 1/5(x) - 7/5;
5x - 20 = 2x - 14
3x = 6 --> x=2

Answers:
Sam's current age = 24The mother's current age = 48=========================================================
Explanation:
s = Sam's age right now
2s = the mother's age right now, since she is twice as old as Sam currently.
In 12 years time, Sam will be s+12 years old.
12 years ago from this current year, the mother was 2s-12 years old.
Since we're told these future and past ages line up, this means s+12 and 2s-12 are the same value
Set the expressions equal to one another and solve for s.
s+12 = 2s-12
s-2s = -12-12
-s = -24
s = 24
Sam is currently 24 years old.
His mother is currently 2s = 2*24 = 48 years old.
12 years ago, his mother was 2s-12 = 48-12 = 36 years old.
12 years from now, Sam will be s+12 = 24+12 = 36 years old.
Since we get 36 each time, this confirms we have the correct answers.
gonzalo nacio el 18 de sptiembre de 1945 si bertha nacio cuatro decadas y un lustro cual es la fecha de nacimiento de bertha
Answer: Bertha nació el 18 de septiembre de 1990.
Step-by-step explanation:
Gonzalo nació el 18 de septiembre de 1945.
Bertha nació cuatro décadas y un lustro después.
Una década son 10 años
Un lustro son 5 años
Entonces 4 décadas y un lustro son:
4*10 años + 5 años = 45 años
Esto significa que Bertha nació 45 años después que Gonzalo.
Entonces si Gonzalo nació en 1945, Bertha nació en el año:
1945 + 45 = 1990
Bertha nació el 18 de septiembre de 1990.
La fecha de nacimiento de Bertha es el 18 de septiembre de 1990.
How many years does a decade have?A decade is composed of 10 years. So, if there are 'x' decades, then that means there are going to be [tex]10 \times x[/tex] years in it.
For this case, we are given that:
Date of birth of Gonzelo is 18th of Sept. 1945
Bertha born after 4 decades and 5 years of Gonzelo's birth.
4 decades = 4 times 10 = 40 years
Thus, 4 decades + 5 years = 40 + 5 = 45 years.
45 years after 1945 uis 1945 + 45 = 1990
Thus, date of birth of Bertha is 18th Sept. 1990

What is the area of a circle with a diameter of 16 centimeters?
A. 50.24
B. 100.48
C. 200.96
D. 803.84
Answer:
A≈201.06
Step-by-step explanation:
so it would be about 200.96
Answer:
C. 200.96
Step-by-step explanation:
First, find the radius by dividing 16 by 2:
16/2
= 8
Use the area formula to find the area:
A = [tex]\pi[/tex]r²
A = [tex]\pi[/tex](8)²
A = 64[tex]\pi[/tex]
A = 201.06
This answer is closest to C, 200.96
So, the correct answer is C. 200.96
Help? I am confuse don how to find the area. I watched a ton of videos, but I don’t get it
Answer:
Step-by-step explanation:
The most basic area formula is the formula for the area of a rectangle. Given a rectangle with length l and width w, the formula for the area is: A = lw (rectangle). That is, the area of the rectangle is the length multiplied by the width.
