For one adult it costs $15

For one child it costs $10

Step-by-step explanation:

So..

One adult = $15

Two children = $20 10×10

= $35

Then..

Two adult = $30 15×15

Three children = $30 10×10×10

= $60

Answer:

p=70+1.25x

Step-by-step explanation:

Answer:

P=1.25x+70

Step-by-step explanation:

So we know that Aaliyah earns $1.25 commission for every computer she sells. No matter what, she will make $70 per day, so that would be our constant. The $1.25 would be our independent variable since it can change depending on the amount of computers x she sells. Therefore, our equation is:

P represents the total pay, 1.25x represents the total commission for x computers, and the 70 is the base pay.

P=1.25+70

Answer:

AC=42

EB=21

BC=26

thats all i know, sorry hope u figure it out

Step-by-step explanation:

The sides are AC = 42, EB = 21, BC = 26, AB = 38 and the measures of angles are ∠ADC = 90°, ∠ABD = 38°, ∠BCA = 52°, ∠DEC = 104°.

Rectangle is a two dimensional figure which has four sides and four angles and all the angles are right angles

Given is a rectangle ABCD.

AC and BD are diagonals intersecting at E.

Given  DB=42, AD=26 and m ∠DAE=52°

(a) Diagonals of a rectangle are of equal length.

AC = DB = 42

(b) Diagonals of a rectangle bisect each other.

DE = EB = DB / 2 = 42/2 = 21

(c) Opposite side are equal.

BC = AD = 26

(d) Using Pythagoras theorem,

AB = [tex]\sqrt{(AC)^2-(BC)^2}[/tex] = [tex]\sqrt{42^2-26^2}[/tex] = 37.947 ≈ 38

(e) Measure of all the interior angles in a rectangle is 90°.

So, ∠ADC = 90°

(f) Given ∠DAE = 52°

∠BAE = 90° - 52° = 38°

ΔBAE is an isosceles triangle, since the two sides which are the bisectors of the diagonals are equal.

So, ∠ABD = ∠BAE = 38°

(g) ∠BCA = ∠DAE [Alternate interior angles]

∠BCA = 52°

(h) Sum of interior angles of a triangle is 180°.

∠DEC + ∠BDC + ∠ACD = 180°

∠BDC = ∠ABD = 38° and ∠ACD = ∠BAE = 38°

∠DEC = 180° - (38° + 38°)

          = 104°

Hence the measures are found.

Step-by-step explanation:

To compare the number of apples to oranges

Number of apples = 12

Number of oranges = 10

Number of apples in terms of oranges :

12 /10 = 1.2

Number of apples = 1.2(number of oranges)

If number of apples = x

Number of oranges = y

x = 1.2y

There are 1.2 times the number of apples than number of oranges.

Answer: B. 6 rides

Step-by-step explanation:

To find this out, deduct all the expenses mentioned from the amount Daniel came to the park with.

= 79.5 - 31.75 - 9.25 - 5.50

= $33.00

Daniel has $33.00 to spend on rides.

If each ride costs $5.50, the number of rides he can go on is:

= 33 / 5.5

= 6 rides

Equation:  y = 12x + 0

Explaination: A proportional relationship is one in which two quantities vary directly with each other. Another way to think about them is that, in a proportional relationship, one variable is always a constant value times the other.

Step-by-step explanation:

with the y= 4x +1

they find the first column by replacing x in the function by 0

meaning if x= 0 then y=4(0) + 1 so y=1

for the second column if x =2 then y= 4(2) +1 so y= 9

for the 3rd one if x =4 then y = 4(4)+1 so y = 17

Answer:

see the explanation below

Step-by-step explanation:

you can type 250 characters in 60 seconds your friend can type 375 characters in 90 seconds do these ratios form a proportion

Given data

you can type 250 characters in 60 seconds

your typing speed = 250/60

= 4.16 characters per seconds

your friend can type 375 characters in 90 seconds

your friends typing speed is

= 375/90

= 4.16 characters per seconds

Since both typing speeds corresponds, hence the ratios are proportional

Answer:

Step-by-step explanation:

Area of the circle = πr² = π7.3² = 53.29π

Area of major sector = 53.29π(285/360) ≈ 132.54 cm²

The area of major sector DFE is 132.5 sq.cm , Option C is the right answer.

The region bounded by the two radii and intercepted arc in a circle is called a sector .

The angle made by the radii to the center of the circle is called central angle .

if the measure of the angle is less than 180 degree then it is called minor sector and if the angle is more than 180 degree , it is called Major Sector.

It is given that

The radii of the circle is 7.3 cm

The angle subtended by the major sector at the center is 285 degree.

The area of the sector is given by

= ([tex]\rm \theta[/tex] / 360) * Area of the circle

Area of the circle is πr²

Area of the sector = ( 285 / 360) * (22/7) * (7.3)²

Area of the sector is 132.5 sq.cm

Therefore , The area of major sector DFE is 132.5 sq.cm , Option C is the right answer.

={(-6-3-0)/3,(8+1+3)/3}=(-3,4)

Answer:

( - 3, 4 )  

Step-by-step explanation:

The centroid of a triangle is the intersection of the three medians of the triangle.

A ( - 6, 8 )

C ( 0, 3 )

Coordinates of the midpoint of AC are D( - 3, 5.5 )

Median BD is x = - 3

Coordinates of midpoint of BC are E( - 1.5, 2 )

[tex]m_{AE}[/tex] = - [tex]\frac{4}{3}[/tex]

Equation of median AE is y = - [tex]\frac{4}{3}[/tex] x

Solve system of equations:

y = - [tex]\frac{4}{3}[/tex] x and x = - 3

( - 3, 4 ) are coordinates of the centroid of the Δ ABC
