Answer:
30 inches squared
Step-by-step explanation:
The formula for a RIGHT triangle is:
[tex]A= \frac{ab}{2}[/tex]
We are given..
a = 5 inchesb = 1 foot = 12 inchesTherefore...
[tex]A = \frac{5(12)}{2}[/tex]
[tex]A=\frac{60}{2}[/tex]
[tex]A = 30[/tex]

I am a 6-digit number one of my 4s is worth 400,000. My 5 is worth 5 [10s]. My other 5 is worth 1/100 as much.My 8 is worth 800.My 2 is worth 2 . My other digit is a 0 what number am I.
Answer:
The question is corrected to get;
405,852
Step-by-step explanation:
The expression of the description when written as follows;
'I am a 6-digit number one of my 4s is worth 400,000. The other 5 is worth 1/100 as much. My 5 is worth 5 (10s). y 8 is worth 800. My 2 is' worth 2. My other digit is a 0 what number am I, we have;
The number of digits in the number = 6
The position of the number 4 = 100,000s, we have;
4xx,xxx
The position of the number 5 is in the 10s position, we have;
4xx,x5x
The other 5 = 50100 = 0.5
Therefore, we have;
4xx,x5x.5
The position of the 8 is the 100s, to give;
4xx,85x.5
The number 2 is in the unit position, therefore, we have;
405,852

A triangle has side lengths of 14 cm and 7 cm. Which could be the value of the third side, 22 cm or 20 cm?
Answer:
Undefined, it can be 20 cm, 22 cm or any value.A triangle has no limitations for any of each three sides.
Step-by-step explanation:
How it works? The triangles have no limits on their sides, but by their angles. Each triangle sums 180 degrees at the inner angles. If you don't have specific values for the angles it is not necessary to get some values for the third side. It could be 1, 2, .... or even 1000.

Answer:
The picture is kinda blurry so I hope I've got it right.
a) x = 20°
b) x = 70°
c) x = 50°
Step-by-step explanation:
a) 2x + 3x + 4x = 180°
9x = 180°
x = 50°
b) (x - 20°) + (x - 20°) + (x + 10°) = 180°
3x - 30° = 180°
3x = 210°
x = 70°
c) (x + 10°) + (x + 20°) + x = 180°
3x + 30° = 180°
3x = 150°
x = 50°

What is the value of the expression 4 4? ____
The park service that administers a state park estimates that there are 495 deer in the park. They decide to remove deer according to the differential equation dP/dt = −0.1P.
a. Show that the solution to the differential equation dP/dt = −0.1P is P = 495e^−0.1t , where t is measured in years and P is the population of deer. Use it to find the deer population in 5 years to the nearest deer.
b. After this 5-year period, no human intervention is taken and the deer population grows again. From that time, the deer population increases directly proportional to 650−P, where the constant of proportionality is k. Find an equation for the deer population P(t) in terms of t and k for this 5-year period.
c. Using the growth model from part b), 1 year later the deer population is 350. Find k.
d. Using the growth model from part b) and the value of k from part c), find lim t→∞ P(t)
The deer population in 5 years is approximately 294 deer.
What are exponential growth and decay?A rise in the resultant quantity for a given quantity is referred to as exponential growth, and a decrease in the resultant quantity for a given quantity is referred to as exponential decay. Over time, exponential functions monitor constant growth. Examples from the actual world include radioactive decay, compound interest, and bacterial proliferation.
a. To solve the differential equation dP/dt = −0.1P, we can separate the variables and integrate:
dP/P = −0.1 dt
Integrating both sides gives:
ln|P| = −0.1t + C
where C is the constant of integration. To solve for C, we can use the initial condition that P = 495 when t = 0:
ln|495| = −0.1(0) + C
C = ln|495|
Substituting this value of C back into the equation gives:
ln|P| = −0.1t + ln|495|
Simplifying using logarithm properties, we get:
ln|P/495| = −0.1t
Exponentiating both sides gives:
|P/495| = e^−0.1t
Taking the absolute value off and multiplying both sides by 495, we get:
P = 495e^−0.1t
To find the deer population in 5 years, we can substitute t = 5 into the equation:
[tex]P = 495e^{-0.1(5)} = 294[/tex] deer (rounded to the nearest deer).
Therefore, the deer population in 5 years is approximately 294 deer.
b. To find an equation for the deer population P(t) in terms of t and k for the period after 5 years, we can use the differential equation:
dP/dt = k(650−P)
Separating the variables and integrating, we get:
∫dP/(650−P) = ∫k dt
Using partial fraction decomposition and integrating, we get:
ln|650−P| = −kt + C
where C is the constant of integration. To solve for C, we can use the initial condition that P = 294 when t = 5:
ln|650−294| = −k(5) + C
C = ln|356| + 5k
Substituting this value of C back into the equation gives:
ln|650−P| = −kt + ln|356| + 5k
Simplifying using logarithm properties, we get:
ln|(650−P)/356| = −kt
Exponentiating both sides gives:
[tex]|(650-P)/356| = e^{-kt[/tex]
Taking the absolute value off and multiplying both sides by 356, we get:
[tex]650-P = 356e^{-kt[/tex]
Solving for P gives:
[tex]P = 650-356e^{-kt[/tex]
Therefore, the equation for the deer population P(t) in terms of t and k for the period after 5 years is P = 650−356e^−kt.
c. Using the growth model from part b), if the deer population is 350 one year later, we can substitute t = 1 and P = 350 into the equation and solve for k:
350 = 650−356e^−k
Solving for [tex]e^{-k[/tex] gives:
[tex]e^{-k = (650-350)/356 = 3/2[/tex]
Taking the natural logarithm of both sides gives:
−k = ln(3/2)
Solving for k gives:
k = −ln(3/2) ≈ 0.4055
Therefore, k ≈ 0.4055.
d. Using the growth model from part b) and the value of k from part c), the long-term behavior of the deer population as t → ∞ is determined by the limit:
lim P(t) as t → ∞
We can use the fact that [tex]e^{-kt[/tex]approaches 0 as t →

(6x^2+3x) + (x^2 - 4x -3)
plz help
Answer:
7x^2 - x -3
Step-by-step explanation:
(6x^2+3x) + (x^2 - 4x -3)
We have to use distributive property first to get rid of the parenthesis, so you simply have to multiply the positive (+) symbol with everything inside the second set of parenthesis.
+ * x^2 = x^2
+ * -4x = -4x
+ * -3 = -3
Now, we rewrite the equation which is
6x^2 + 3x + x^2 - 4x -3
Now you simply combine like terms.
6x^2 + x^2 = 7x^2
3x-4x = -x
The answer will be
7x^2 - x -3

Answer:

10. 6
11. 12
12. 24
Step-by-step explanation:
The length of each segment is AB = 6, BC = 6, AC = 12, CD = 6, CE = 12, AE = 24
What is the length?It is the measure of distance between the two points is called a length.
D is the mid-point of CE. Then
CD = DE = 6
B is the mid-point of AC. Then
AB = BC
C is the mid-point of AE. Then
AC = CE
AB + BC = CD + DE
AB + AB = CD + CD
2 AB = 2 CD
AB = CD
AB = 6
Then
AB = 6
BC = AB = 6
AC = AB + BC = 6 + 6 = 12
CD = DE = 6
CE = CD + DE = 6 + 6 = 12
AE = AB + BC + CD + DE = 6 + 6 + 6 + 6 = 24

Sasha buys bagels for her garage sale customers she buys all the chocolate chip bagels and half of the plain bagels each bagel cost 2.50 how much does Sasha spend on bagels
The question is incomplete:
Sasha buys bagels for her garage sale customers she buys all the chocolate chip bagels and half of the plain bagels each bagel cost 2.50 how much does Sasha spend on bagels? The table that shows the types of bagels sold at the bagel shop on Friday is attached.
a. $70
b. $20
c. $90
d. $110
Answer:
c. $90
Step-by-step explanation:
First, you need to find the amount of bagels that Sasha purchased. The statement indicates that she buys all the chocolate chip bagels and the table shows that 28 chocolate chips bagels were sold, so that's the amount she purchased of this type of bagels. Also, the statement indicates that she buys half of the plain bagels and the table says that 16 plain bagels were sold, so you have to divide this amount by 2:
16/2=8
Then, you have to add the amount of chocolate chips bagels plus the amount of plain bagels that Sasha purchased:
28+8=36
Now that you know the amount of bagels that Sasha purchased, you have to multiply this for 2.50 that is the price per bagel:
36*2.50=90
According to this, the answer is that Sasha spends $90 on bagels.
