JUST ANSWER CORRECTLY THE ANSWER 12 IS WRONG PLEASE GIVE THE RIGHT ANSWER
Answer:
Step-by-step explanation:
given tanB= 4/3
so sinB=4/5
n cosB=3/5
given BC=15
BA=BC*cosB
=15*3/5
=9
AC=BC*sinA
=15*4/5
=12
Triangle ABC and DBE are similar by AAA
DB= BA-AD
=9-3
=6
DB/BA=DE/AC
6/9=DE/12
DE=12*6/9
=8
Answer:
DE = 8
Step-by-step explanation:
ΔABC and ΔDBE are similar.
As they share the same angles, the sides are in proportion to each other.
Therefore, we can solve using ratios.
Tan trigonometric ratio
[tex]\sf \tan(\theta)=\dfrac{O}{A}[/tex]
where:
[tex]\theta[/tex] is the angleO is the side opposite the angleA is the side adjacent the angleGiven:
[tex]\sf \tan (B)=\dfrac{4}{3}[/tex]
Therefore:
[tex]\implies \sf \dfrac{DE}{BD}=\dfrac{AC}{BA}=\dfrac{4x}{3x}[/tex]
We know that BC = 15 and that AC : BA = 4x : 3x
Using Pythagoras' Theorem:
[tex]\implies \sf (3x)^2+(4x)^2=15^2[/tex]
[tex]\implies \sf 9x^2+16x^2=225[/tex]
[tex]\implies \sf x^2(9+16)=225[/tex]
[tex]\implies \sf x^2=9[/tex]
[tex]\implies \sf x=3[/tex]
Therefore,
⇒ AC = 4 · 3 = 12
⇒ BA = 3 · 3 = 9
Now we have found the length of BA, we can find the length of BD:
⇒ BD = BA - DA
⇒ BD = 9 - 3
⇒ BD = 6
As DE : BD = 4x : 3x and BD = 6 then:
⇒ 3x = 6
⇒ x = 2
Therefore, to find DE, substitute x = 2:
⇒ DE = 4x
⇒ DE = 4(2)
⇒ DE = 8

A school is going on a field trip to a museum. The ratio of men to women to children is 1:3:20 and there are 216 people on this trip. What is the difference between the number of children and adults?
Answer:The difference between the number of children and adults=153
Step-by-step explanation:
ratio of men to women to children is 1:3:20
Total RATIO = 1+ 3+ 20= 24
Number of men = ratio of men / Total ratio x Total Number of people on the trip =
= 1/24 x 216= 9 men
Number of women=ratio of women / Total ratio x Total Number of people on the trip = 3/ 24 x 216 = 3x 9= 27 women
Number of children=ratio of Children/ Total ratio x Total Number of people on the trip = 20/24 x 216= 20 x9 = 180 children
The difference between the number of children and adults will be 180 -27 = 153

At $350 per person, an airline anticipates selling 200 tickets for a particular flight. At $450 per person the airline anticipates selling 100 tickets for the same flight .
Answer:
C =-x + 550
Step-by-step explanation:
Complete question
At $350 per person, an airline anticipates selling 200 tickets for a particular flight. At $450 per person the airline anticipates selling 100 tickets for the same flight .Find the linear equation between the cost per ticket and the number of tickets.
Find the complete question attached
Let x be the total number of tickets sold
C be the cost per ticket
If C = $350, x = 200
when C = $450, x = 100
Get the slope
m = C2-C1/x2-x1
m = 450-350/100-200
m = 100/-100
m = -1
Substituting into the point slope form of the equation;
C - C1 = m(x-x1)
Substituting m = -1, C1 = 350 and x1 = 200
C - 350 = -1(x-200)
C - 350 = -x + 200
C = -x + 200 + 350
C = -x + 550
Hence the required linear equation is C =-x + 550
The linear equation should be C =-x + 550
Linear equation:Here we assume x be the total number of tickets sold
And,
C be the cost per ticket
Since C = $350, x = 200 and C = $450, x = 100
So, here the slope should be
[tex]m = C2-C1\div x2-x1\\\\m = 450-350\div 100-200\\\\m = 100\div -100[/tex]
m = -1
Now here we Substituting into the point slope form
So,
C - C1 = m(x-x1)
Here m = -1, C1 = 350 and x1 = 200
Now
C - 350 = -1(x-200)
C - 350 = -x + 200
C = -x + 200 + 350
C = -x + 550

Solve the system of equations by substitution. Show all work neatly on your work page. Checking your work is wise. :)
3x + 2y = -10
y = -5x + 9
Answer:
(4, -11)
Step-by-step explanation:
We are given the system of equations:
[tex]\displaystyle \begin{cases} 3x+2y=-10\\ y=-5x+9\end{cases}[/tex]
And we want to solve by substitution.
Notice that y is isolated in the second equation.
Therefore, we can substitute the second equation into the first. This gives us:
[tex]3x+2(-5x+9)=-10[/tex]
Now, we can solve for x.
First, distribute:
[tex]\displaystyle 3x-10x+18=-10[/tex]
Next, we can combine like terms:
[tex]-7x+18=-10[/tex]
Subtract 18 from both sides:
[tex]-7x=-28[/tex]
And divide both sides by -7:
[tex]x=4[/tex]
So, the value of x is 4.
Using the second equation then, we can solve for y:
[tex]y=-5x+9[/tex]
Since we know that x = 4:
[tex]\displaystyle y = - 5(4) + 9 = -20 + 9 = -11[/tex]
So, our solution is (4, -11).
To check, we can simply substitute the x and y values and see if the two equations are true.
For the first equation:
[tex]3(4)+2(-11)=12-22=-10\stackrel{\checkmark}{=}-10[/tex]
And for the second equation:
[tex]-5(4)+9=-20+9=-11\stackrel{\checkmark}{=}-11[/tex]
Since both statements are true, (4, -11) is indeed correct!

Answer: 198 miles
Step-by-step explanation:
Here's the complete question:
The Nile river is 4160 miles long, you want to spend three weeks traveling the entire length of the river. Estimate the number of miles you should travel each day.
We should note that 7days = 1 week
3 weeks = 3 × 7 = 21 days.
The number of miles that should be travelled each day will be:
= 4160 / 21
= 198 miles
