Answers

Answer:

y=3.5x-2

Step-by-step explanation:

y=mx+c

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?

Answers

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

if the original quantity is 12 and the new quantity is 15, what is the percentage increase

Answers

Answer:

25%

Step-by-step explanation:

Given data

original quantity =12

new quantity =15

% increase= new-original/original *100

% increase= 15-12/12 *100

% increase= 3/12 *100

% increase=0.25 *100

% increase=25%

hence the increase is 25%

JUST ANSWER CORRECTLY THE ANSWER 12 IS WRONG PLEASE GIVE THE RIGHT ANSWER

Answers

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

AC=BC*sinA

=15*4/5

=12

Triangle ABC and DBE are similar by AAA

DB= BA-AD

=9-3

DB/BA=DE/AC

6/9=DE/12

DE=12*6/9

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 angle

Given:

[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

Solve system by elimination

9x + 3y = 24
10x - 2y = 0

Answers

Answer:

(1, 5 )

Step-by-step explanation:

Given the 2 equations

9x + 3y = 24 → (1)

10x - 2y = 0 → (2)

Multiplying (1) by 2 and (2) by 3 and adding the result will eliminate the y- term

18x + 6y = 48 → (3)

30x - 6y = 0 → (4)

Add (3) and (4) term by term to eliminate y

48x + 0 = 48

48x = 48 ( divide both sides by 48 )

x = 1

Substitute x = 1 into either of the 2 equations and solve for y

Substituting into (1)

9(1) + 3y = 24

9 + 3y = 24 ( subtract 9 from both sides )

3y = 15 ( divide both sides by 3 )

y = 5

solution is (1, 5 )

Some produce in grocery stores is stored for weeks or even months before being sold. In contrast, local farmers can sell you fruits and vegetables that were picked fresh from the field that morning.
