The area of a triangle is 36 4/5 units squared and the height of the triangle 9 1/5 what is the length of the triangles base
Answers
Answer:
Height = 8 units
Step-by-step explanation:
Area of a triangle = [tex]36\frac{4}{5}[/tex] square units
= [tex]\frac{184}{5}[/tex] square units
Height of the triangle = [tex]9\frac{1}{5}[/tex] units
= [tex]\frac{46}{5}[/tex] units
Formula to calculate the area of a triangle is,
Area = [tex]\frac{1}{2}(\text{Base})(\text{Height})[/tex]
[tex]\frac{184}{5}= \frac{1}{2}\times (\frac{46}{5})\times (\text{Height})[/tex]
[tex]\frac{184}{5}= (\frac{46}{10})\times (\text{Height})[/tex]
Height = [tex]\frac{184}{5}\times \frac{10}{46}[/tex]
= [tex]\frac{368}{46}[/tex]
= 8 units
Therefore, height of the given triangle is 8 units.

Answer:
396π.cm^3
Step-by-step explanation:
ere's your solution
=> height of cylinder = 11 cm
=> radius of cylinder = 6 cm
=> volume = πr^2h
=> putting the value of radius and height in formula
=>volume = 6^2*11 π
=> volume = 36*11 π

A system of equations is shown, where k is a constant. If the lines represented by the equations in the system are graphed in the xy-plane, for what value of k would the lines coincide?
A. -4
B. 1
C. 2
D. -4
Answers
The value of 'k' for the given system of equation that coincides is 4
k=4
Given :
System of equations
[tex]2x+y=40 \\kx+2y=80[/tex]
The given equation is in the form of ax+by=c
When the two lines coincides then
[tex]\frac{a_1}{a_2} =\frac{b_1}{b_2} =\frac{c_1}{c_2}[/tex]
Lets make the coefficients proportional to each other and then solve for k
[tex]\frac{2}{k} =\frac{1}{2} =\frac{40}{80} \\\frac{2}{k} =\frac{1}{2} =\frac{1}{2} \\\\\frac{2}{k} =\frac{1}{2} \\4=k\\k=4[/tex]
The value of k from the given system of equation is 4
When the line coincides then the value of k is 4

Solve the two-step equation. 14=31.7-3x
Answers
Answer:
x=5.9
Step-by-step explanation:
First, you want to isolate x so you have to subtract 31.7 from both sides. This will make the equation -3x=-17.7. Because they are both sides are negative, you can change both sides to positive so it will be 3x=17.7. Next, you want x to be 1 so you have to divide 3 in both sides. This will make the equation x=17.7/3. Simplify that to get x=5.9.

If the ratio of boys to girls in the school band is 2 to 3, which of these show possible numbers
of the boys and girls in band.
A. 24 boys, 36 girls
B. 20 boys, 35 girls
C. 36 boys, 24 girls
D. 35 boys, 20 girls
Answers
Answer:
A
Step-by-step explanation:
Simply guess and check, meaning the boys category must be divisible by 2 and the girls category must be divisible by 3
A: 24 boys ÷ 2 = 12 (equals a whole number so it is divisible; not a decimal)
36 girls ÷ 3 = 12 (both of the boys and girls are divisible by their corresponding numbers)
Yes
Now make sure the boys are a lower count than the girls as the ratio says it should be 2 to 3, meaning there are more girls than boys
B: 20 ÷ 2 = 10 (divisible)
35 ÷ 3 = 11.666 (this is a decimal answer so it is not divisible)
No
C: 36 ÷ 2 = 18
24 ÷ 3 = 8
Yes, they are divisible
Now lets check if boys have a lower count than girls
36 boys > 24 girls
This is not the solution as it doesn't reflect the correct ratio of less boys than girls
D: 35 ÷ 2 = 17.5 (not divisible)
20 ÷ 3 = 6.66 (not divisible)

how do i describe what each variable and parameter means in an exponential equation
y=a(b)x
Answers
Answer:
A general exponential equation is written as:
y = a*(b)^x
Where:
y represents the amount of something as a function of the variable x, where x is an independent variable.
a is the initial amount, this is, the value of y when x = 0.
b is the rate of growth, this defines how much changes the value of y as x increases.
