Answer:
P(t) = 20,000 * e^0.173287t
Step-by-step explanation:
P(t) = Po * e^k*t
Po = 20,000
t = 4
P(t) = 40,000
40,000 = 20,000 * e^4k
2 = e^4k
ln 2 = ln e^4k
ln 2 = 4k * ln e
ln 2 = 4k
0.173287 = k

A soccer team has 12 girls and 18 boys. The team is split into groups that have the same ratio of girls to boys as that of the whole team. How many girls are in a group that has 12 boys?
Answer: 8 girls
Step-by-step explanation:
The team is split into groups that have the same ratio as the whole team.
This means that every group must obey this ratio:
12 girls : 18 boys
At the lowest form (dividing both sides by 6), the ratio is:
2 : 3
Every group must therefore be in a ratio of; 2 : 3.
In a team group that has 12 boys, the number of girls is:
2 : 3
x : 12
3x = 24
x = 24 / 3
x = 8 girls

Answer:-5+x<-1
Step-by-step explanation:
Answer:
H. -5 + x < -1
Step-by-step explanation:
Okay so let's first look at our little graph thing. What is it saying? It's telling us that what ever x is, it is NOT 4 (because the circle is not filled in) and it is less than 4 (because it's all shaded in before 4). Now that we know this, lets look at our possible answers.
F. x - 3 < 7
Now, for all of these possible answers, we can solve them exactly like normal equations (like x - 3 = 7).
x - 3 < 7
[add 3 to both sides to leave the x by itself]
x < 10
Whoa, that's not right! We don't even have 10 on our graph, so F is out of the running.
G. x + 6 [tex]\leq[/tex] 10
Okay, let's work smarter, not harder here. So we can see that there is a greater than or equal to sign there. So even if we solve it and we get 4 as the answer, our graph doesn't include 4. So we can throw this answer out right away.
H. -5 + x < -1
Solve like a normal equation in the first one.
-5 + x < -1
[add 5 to both sides to leave the x by itself]
x < 4
Hey! We got something! So let's read this with words. So whatever x is, it does not include 4, and is less than 4. So now looking back on our first brainstorm of the graph, this is in line with what we want.
So this is the answer! Yay!
Just for fun let's look at the last possible answer.
I. x - 8 > -4
Again, solve like a normal equation.
x - 8 > -4
[add 8 to both sides to leave x by itself]
x > 4
Oh! Another 4! But this time the sign is different. Let's read it again with words. So whatever x is, it does not include 4 (ok, good), and is greater than 4 (oh, not good). Our graph showed us that x is less than 4. So this answer is not the answer.
So again, we keep H. as our correct answer.

-10
0
0 1
9
Answer:
9
Step-by-step explanation:
Mathematically, OPPOSITES are the same distance away from zero, but on opposite sides of zero on the number line. Use the drawing tools to plot a point at the opposite of each colored point. The absolute value of 0 is 0. Two numbers are opposites if they have the same absolute value but different signs. Opposites are the same distance from 0 on a number line, and they are on opposite sides of 0. The opposite of 0 is 0.

When rounding to the nearest hundred thousand what is the greatest whole number that rounds to 400,000
Answer:
449,999
Step-by-step explanation:
Given that:
Greatest whole number that round to 400,000 when rounding to the nearest hundred thousand :
To obtain the greatest whole number which rounds to 400,000, the whole number is greater Tha 400,000 and its 10 thousand digit in the number or value to be rounded must be lesser than 5.
The value would be 449,999 ; here z the 10 thousand value which is 4 is rounded to zero since it is not up to 5 and the subsequent digits also rounded to 0 to give ;
400,000 (nearest hundred thousand).
a polygon has 50 sides
all but one of its angle is 170 degrees
what is the size of the other angle?
Answer:
.2 degrees
Step-by-step explanation:
180-170 is 10
10/50 is .2
The size of the other angle will be 0.2 degrees.
What are polynomials?A polynomial in mathematics is an expression made up of coefficients and indeterminates and involves only the operations of multiplication, addition, subtraction, and non-negative integer exponentiation of variables.
The angle is defined as the span between two intersecting lines or surfaces at or close to the point where they meet.
It is given that a polygon has 50 sides but one of its angles is 170 degrees.
The remaining angle will be calculated as:-
180-170 = 10
The size of the other angle is calculated below:-
Angle = 10/50
Divide the value 10 by 50 to get the angle.
Angle = 0.2
Therefore, the size of the other angle will be 0.2 degrees.

Write and solve an inequality to find the values of x for which the perimeter of the rectangle is less than 140.
Select the correct answer below and fill in the answer box to complete your choice.
PLZ HELP MEEE
Given:
Length of the rectangle = [tex]x+4[/tex]
Width of the rectangle = [tex]x[/tex]
The perimeter of the rectangle is less than 140.
To find:
The inequality for the given situation and solve it.
Solution:
We have,
[tex]l=x+4[/tex]
[tex]w=x[/tex]
We know that, the perimeter of a rectangle is
[tex]P=2(l+w)[/tex]
[tex]P=2(x+4+x)[/tex]
[tex]P=2(2x+4)[/tex]
[tex]P=4x+8[/tex]
It is given that the perimeter of the rectangle is less than 140.
[tex]P<140[/tex]
[tex]4x+8<140[/tex]
[tex]4x<140-8[/tex]
[tex]4x<132[/tex]
Divide both sides by 4.
[tex]x<\dfrac{132}{4}[/tex]
[tex]x<33[/tex]
Therefore, the correct option is A because the sign of inequality is < and the solution of inequality is [tex]x<33[/tex].
The ratio of daisies to roses is 2 daisies to 7 roses.
If there are 6 daisies, how many roses are there?
There are
roses.
The proportion is solved and the number of roses is R = 21
What is Proportion?The proportion formula is used to depict if two ratios or fractions are equal. The proportion formula can be given as a: b::c : d = a/b = c/d where a and d are the extreme terms and b and c are the mean terms.
The proportional equation is given as y ∝ x
And , y = kx where k is the proportionality constant
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Given data ,
Let the proportion be represented as A
Now , the value of A is
If the ratio of daisies to roses is 2:7, this means that for every 2 daisies, there are 7 roses.
If there are 6 daisies, we can use this ratio to find out how many roses there are.
2 daisies = 7 roses
On simplifying the proportion , we get
1 daisy = 7/2 roses (dividing both sides by 2)
So, if there are 6 daisies:
6 daisies = (7/2) x 6 = 21 roses
Hence , there are 21 roses

Trying again, but im attaching the screenshot this time!
Answer:
the area of a triangle is 9 because 4.24 times 4.24 equals 17.9776 estimated is 18 divided by 2 is 9 times 4 is 36. Now we divide 36 by 2 so we know what the area of the two trapezoids so we know the top and the bottom which is 18. The area of the square in between the triangles is 4.24 times 6 which is 25.22 estimated is 26. Now we add 26 with 18 which is 34. Now we have to find the area of the rectangle to do this we need to multiply 7.24 and 2 we need to do this so we know the length of the rectangle which is 14.48 estimated is 14. Now that we know the length we multiply it with the height which is 6, 14 times 6 equals 84.
84 is the rectangles area and the area for the trapezoids is 36.
84 plus 18 plus 18 equals 120 squared
