Answer:

D.

Step-by-step explanation:

If the triangle has one angle that is equal to 90 then it is a right triangle.

Equation 1 would be: 3a+2C

Equation 2 would be: 5a+3C

The system of equations are solved and the cost of adult ticket and child tickets are $ 6 and $ 4 respectively

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the equation be represented as A

Now , the value of A is

Let the adult tickets be a

Let the child tickets be c

Group A buys 3 adult tickets and 2 child tickets and pays a total of $26

So , 3a + 2c = 26   be equation (1)

And , Group B buys 5 adult tickets and 3 child tickets and pays $42

So , 5a + 3c = 42   be equation (2)

On simplifying , we get

Multiply equation (1) by 5 and equation (2) by 3 , we get

15a + 10c = 130   be equation (3)

15a + 9c = 126   be equation (4)

Subtracting equation (4) from equation (3) , we get

c = $ 4

Therefore , the cost of child ticket is $ 4

Substituting the value of c in equation (1) , we get

3a + 2 ( 4 ) = 26

3a + 8 = 26

Subtracting 8 on both sides , we get

3a = 18

Divide by 3 on both sides , we get

a = $ 6

Therefore , the cost of adult ticket is $ 6

Hence , the system of equations are solved

Answer:

x=5 cm,y=12 cm

Step-by-step explanation:

We are given that

RQ=3 m

PQ=4 cm

RP=x cm

RS=13 cm

SP=y cm

We know that Pythagoras theorem

[tex](Hypotenuse)^3=(base)^2+(perpendicular\;side)^2[/tex]

In right triangle RQP

Using Pythagoras theorem

[tex]RP^2=RQ^2+PQ^2[/tex]

Substitute the values

[tex]x^2=3^2+4^2[/tex]

[tex]x^2=9+16[/tex]

[tex]x^2=25[/tex]

[tex]x=\sqrt{25}=5[/tex]cm

Now,

In triangle RPS

[tex]RS^2=RP^2+SP^2[/tex]

[tex](13)^2=5^2+y^2[/tex]

[tex]169=25+y^2[/tex]

[tex]169-25=y^2[/tex]

[tex]144=y^2[/tex]

[tex]y=\sqrt{144}=12[/tex] cm

Answer:

$40

Step-by-step explanation:

use y = mx + b  

y = amount saved = ?

m = amount saved per week = $10

x = time (in  months) saving = 2.5

b = money jerry started with = $15

plug in:

y = (10)(2.5)+15

y = $40

Answer:

AAA (or AA)

Step-by-step explanation:

Prove ΔBEC ~ ΔDEA

(using three angles is unnecessary because you can just use Angle Angle to prove similarity)

First, m∠BCE = m∠EAD because of alternate interior angles.

Then, m∠ADE = m∠CBE  because of alternate interior angles.

m∠BEC = m∠AED because of vertical angles

Thus, ΔBEC ~ ΔDEA because of Angle Angle Angle [AAA] (or AA if you only chose to use 2 angles)

Answer:

3(3x + 2y) and 9x + 6y

Step-by-step explanation:

3(x + 3y + 2x - y)

= 3 (x + 2x) + (3y - y)

= 3 (3x + 2y)

= (3 • 3x) + ( 3 • 2y)

= 9x + 6y

Answer:

Look below! Branliest please!

Step-by-step explanation:

To find the volume, we multiply 12 by the height and then by 3.14. So for 1, we get 1*12 which equals 12, then we multiply that by 3.14 and we get 37.68. So we do that for all of them.

1*12*3.14 = 37.68

3*12*3.14 = 113.04

5*12*3.14 = 118.4

7*12*3.14 = 263.76
