Answer:
P = (13h+k+6m) cm
Step-by-step explanation:
Given that,
The side lengths of a triangle are :
(4h + 2k) cm, (9h + 4m) cm, and (2m - k) cm
We need to find the perimeter of the triangle.
We know that,
Perimeter = sum of all sides
So,
P = (4h + 2k)+(9h + 4m)+(2m - k)
= (4h+9h)+(2k-k)+(4m+2m)
= 13h+k+6m
Hence, the perimeter of the triangle is (13h+k+6m) cm.

Given the following table and graph write the equation to represent the exponential function.
Answer:
The exponential equation is y = -2×(1/2)^x
Step-by-step explanation:
Ok we have a couple things to note here:
1) The horizontal asymptote of the function is the x axis (always nice)
2) At x=0, y=-2 (i.e, this function will be multiplied by -2 bc the exponent part will transform into one at x=0)
3) Then we need to ascertain the base of the exponential. Based on the facts that at x=1, y=-1 and the "a-value" is -2, we can set up an equation to find b:
y=a×b^x----> -1 = (-2)(b) ------> b=1/2
Therefore, the exponential equation is y = -2×(1/2)^x
Test:
At x = 0, y= -2
At x = -1, y = (-2)*(1/2)^-1 = (-2)*2 = -4
At x=2, y = (-2)*(1/2)^2= (-2)*(1/4) = -1/2
Thus we can be quite certain that this is correct

Three straight lines intersect at $O$, and ray $\overrightarrow{OD}$ divides $\angle COE$ into two angles of equal measure. The ratio of $\angle COB$ to $\angle BOF$ is $7:2$. What is the number of degrees in $\angle COD$?
Answer:
12
Step-by-step explanation:
m xxq
The required measure of an angle is ∠COD = 40°.
What are the vertical angles?When two lines intersect at a location, vertical angles are generated. They are always equal to each other.
Let's call the measure of [tex]$\angle COE$[/tex] x degrees.
Since [tex]$\overrightarrow{OD}$[/tex] divides [tex]$\angle COE$[/tex] into two angles of equal measure, the measure of each of those angles is [tex]$\frac{x}{2}$[/tex] degrees.
Since the measure of [tex]$\angle COB$[/tex] is 7 times the measure of [tex]$\angle BOF$[/tex], we have [tex]$\angle COB = 7\angle BOF$[/tex]. The sum of the measures of the angles of a triangle is [tex]$180^\circ$[/tex], so we can set up the equation [tex]$\angle COB + \angle COE + \angle BOF = 180^\circ$[/tex]. Substituting [tex]$7\angle BOF$[/tex] for [tex]$\angle COB$[/tex], we have:
[tex]$7\angle BOF + x + \angle BOF = 180^\circ$[/tex]
Solving for [tex]$\angle BOF$[/tex], we find that [tex]$\angle BOF = 20^\circ$[/tex].
The measure of [tex]$\angle COD$[/tex] is equal to the measure of[tex]$\angle COE$[/tex] minus the measure of [tex]$\angle COD$[/tex], so [tex]$\angle COD = x - 2\cdot 20^\circ = x - 40^\circ$[/tex].
Since the measure of [tex]$\angle COE$[/tex] is equal to [tex]$2\angle COD$[/tex], we have [tex]$x = 2(x - 40^\circ)$[/tex], which simplifies to [tex]$x = 80^\circ$[/tex].
Therefore, the measure of [tex]$\angle COD$[/tex] is [tex]$80^\circ - 40^\circ = {40^\circ}$[/tex].

Answer: 0.25g<2.50.... g<10
Step-by-step explanation: Let us say that the number of gumballs bought is represented by the variable g. In this case, the question is asking how many gumballs can be bought without surpassing the price of $2.50. We know that each gumball is $0.25, therefore the number of gumballs we buy times $0.25 has to be less than $2.50. Hence, the inequality would be 0.25g<2.50. If we were to solve this then g<2.50/0.25-----> g<10. In conclusion, the number of gumballs you can buy has to be less than 10. Thank you!

Answer:
the chances of her picking a yellow one is 6 in 15
Step-by-step explanation:
all you have to do is divide the color that you are trying to find the probability of by the amount of that object is if that makes sense.

Deposited 3,000$ and it earned 300$ in simple interest after 5 years what’s the interest rate
Answer:
The interest rate is 2%
Step-by-step explanation:
Simple Interest
Unlike compound interest where the interest earned in the compounding periods is added to the new principal, simple interest only considers the principal to calculate the interest.
The interest earned is calculated as follows:
I=P.r.t
Where:
I = Interest
P = initial principal balance
r = interest rate
t = time
The principal is P=$3,000 and it earned I=$300 in t=5 years. Thus the interest rate can be calculated by solving for r:
[tex]\displaystyle r=\frac{I}{P.t}[/tex]
[tex]\displaystyle r=\frac{300}{3,000*5}[/tex]
[tex]\displaystyle r=\frac{300}{15,000}[/tex]
r = 0.02
The interest rate is 2%
