On a certain planet, Continent X has an area of 6.23*10^6 square miles and Continent Y has an area of 63,600,000 square miles. How many times larger is Continent Y than Continent X?
Answer:
Step-by-step explanation:
Continent X =6.23*10^6
Continent Y= 63,600,000
rounded = 60,000,000
Scientific notation = 6*10^7
Now round continent X= 6.23 or 6
Continent X= 6*10^6
6*10^7/ 6*10^6 = 1*10^(7-6)
= 1*10^1
= 1*10
= 10
So your answer would be 10.
I hope that helps
Answer:
Step-by-step explanation:Continent X =6.23*10^6
Continent Y= 63,600,000
rounded = 60,000,000
Scientific notation = 6*10^7
Now round continent X= 6.23 or 6
Continent X= 6*10^6
6*10^7/ 6*10^6 = 1*10^(7-6)
= 1*10^1
= 1*10
= 10
So, your answer would be 10 I would have done it this way too not trying to copy(:

Answer:
y = 88
Step-by-step explanation:
Don't worry about the other stuff, just worry about what's in the triangle that has Y.
53°, 39°, and y°
the sum should be equal to 180 so add 53 adn 39 and subtract it from 180.
180 - (53 + 39) = y
180 - 92 = y
88 = y
Hope this helped! Pls Brainliest my answer! It would help amd mean a lot! ;)

Anyone know how to do this??
Answer:
y = (-1/6)x - 1
Step-by-step explanation:
y = 6x - 2
find the reciprocal of 6 which is -1/6 then find the y-intercept (b)
y = (-1/6)x + b
-2 = (-1/6)(6) + b
-2 = -1 + b
+1 +1
-1 = b
Answer:
should be nigitive
Step-by-step explanation:
Y=mx+b
M- represents the slope and its constant
B- represents the y-intersect

Katherine wants to prove that the measures of the interior angles of a triangle have a sum of 180' She draws a triangle and extends one of the sides through a vertex. She then draws a line through th
Vertex thai paralel to the opposite side as shown in the diagram below
Answer:
The statements that must be true are;
A. m∠1 = m∠5
B. m∠2 = m∠4
C. m∠3 + m∠4 + m∠5 = 180°
Step-by-step explanation:
The given parameters are;
The fact Katherine wants to prove = The sum of the measures of the interior angles of a triangle = 180°
The line Katherine drew passing through the vertex = Parallel to the opposite side of the triangle
Therefore we have;
1) m∠1 and m∠5 are corresponding angles and m∠1 = m∠5 for corresponding angles of parallel lines having the same transversal
2) m∠2 and m∠4 are alternate interior angles and m∠2 = m∠4 for alternate interior angles of parallel lines having the same transversal
3) m∠3 and m∠4 and m∠5 are angles on a straight line and angles on a straight line are supplementary
∴ m∠3 + m∠4 + m∠5 = 180°, by the definition of supplementary angles
Therefore, m∠3 + m∠2 + m∠1 = 180° (substitution property)
m∠3 + m∠2 + m∠1 = Sum of interior angles of a triangle = 180°.

The height of a small rock falling from the top of a 124-ft-tall building with an initial downward velocity of -30 ft/sec is modeled by
the equation h(t) = -16% - 30t + 124, where t is the time in seconds. For which interval of time does the rock remain in the air?
O
t = 2
-2
0
t> 2
Answer:
For the time interval 0 to 2 the ball is in the air.
Select the options according to this.
Step-by-step explanation:
The equation should be [tex]h(t)=-16t^{2} -30t+124[/tex]
Let's find the x intercepts to answer this question.
To find x intercept where the h(t) is 0.
[tex]-16t^{2} -30t+124=0[/tex]
Solve the equation for t.
Use quadratic formula to solve the equation.
a=-16
b=-30
c=124
[tex]x=\frac{-b+/- \sqrt{b^{2}-4ac } }{2a}[/tex]
Plug in the values of a, b and c into the formula
[tex]x=\frac{30+/-\sqrt{(-30)^{2}-4(-16)(124) } }{2(-16)}[/tex]
Simplify it
[tex]x=\frac{30+/- \sqrt{900+7936} }{-32}[/tex]
[tex]x=\frac{30+/-\sqrt{8836} }{-32}[/tex]
[tex]x=\frac{30+/-94}{-32}[/tex]
Simplify it to get two values for x
[tex]x=\frac{30+94}{-32} =-3.875\\\\x=\frac{30-94}{-32} =2[/tex]
x can not be negative, here x represents time t.
So, it starts from 0 and remains in the air for 2 seconds.

Am I right or wrong if I’m wrong please tell and with explanation
========================================================
Explanation:
Let's say there are 100 students total. You can start with any number you want, but I'm picking a large round number to work with.
3/5 of the total voted, so (3/5)*100 = 0.6*100 = 60 people voted
Of the 60 who voted, 3/4 of those went to the winning candidate.
3/4 of 60 = (3/4)*60 = 0.75*60 = 45
We have 45 people who voted for the winning candidate out of 100 total students, so,
45/100 = (9*5)/(20*5) = 9/20
Meaning that 9/20 of the student body voted for the winning candidate.
--------------------------------
You could also multiply the two given fractions to get the same answer
(3/5)*(3/4) = (3*3)/(5*4) = 9/20
When multiplying, you multiply the numerators together and the denominators together. Reduce the fraction if possible.

Actual roots of f(x)=2x^2+2x-24
[tex]f(x) = 2 {x}^{2} + 2x - 24 [/tex]
[tex]f(x) = 2( {x}^{2} + x - 12) [/tex]
[tex]0 = 2( {x}^{2} + x - 12)[/tex]
Divided sides by 2
[tex] {x}^{2} + x - 12 = 0 [/tex]
[tex](x + 4)(x - 3) = 0[/tex]
_________________________________
[tex]x + 4 = 0[/tex]
[tex]x = - 4[/tex]
_________________________________
[tex]x - 3 = 0[/tex]
[tex]x = 3[/tex]
Thus the actual roots are -4 and 3.....
And we're done.

Answer:
x= 3, -4
Step-by-step explanation:
Set 2 x ² + 2 x − 24 equal to 0 .
2 x ² + 2 x − 24 = 0
Solve for x .
Factor the left side of the equation.
2 ( x² + x − 12 ) = 0
Factor
x ² + x − 12 using the AC method.
2 ( x − 3 ) ( x + 4 ) = 0
If any individual factor on the left side of the equation is equal to 0 , the entire expression will be equal to 0 .
x − 3 = 0
x + 4 = 0
Add 3 and subtract 4 to both sides of the equation.
x = 3
x = -4

Answer: Domain is [1,3], Range is [304,391]
Step-by-step explanation:
Domain is just the x values the table has from lowest to highest. Period is the x values so domain is [1,3]
Range is the y values from lowest to highest the lowest y is 304 and highest is 391, so you use those two numbers to get [304,391]
is 0.33 rational or irrational
Answer: rational
Step-by-step explanation:
0.33\overline{3} is a rational number because it is the result we get when we divide 1 by 3, or equivalently, because it is a solution to 1=3x.
