Answer: The amount raised by Ariana in the first two weeks =$480
Step-by-step explanation:
Given: The first week she raises 30% of $600 .
The second week she raises 50% of the $600.
Amount raised in the first week = 50% of $600
= 0.50 x 600
= $ 300
Amount raised in the second week = 30% of $600
=0.30 x 600
= $180
The amount raised by Ariana in the first two weeks = $300+$180
= $480
Hence, The amount raised by Ariana in the first two weeks =$480

Answer:
The way I was taught to do it is to change value into a total fraction, then multiple the numerators together, multiply the denominators together, and finally reduce as far as possible.

Below is the table of values of a function. Write the output when the input is n.
Answer:
when input = n, Output = 4n
Step-by-step explanation:
Output = k(input)
Where,
k = constant
Find k When output = 8 and input = 2
Output = k(input)
8 = k(2)
8 = 2k
k = 8/2
k = 4
Find k When output = 28 and input = 7
Output = k(input)
28 = k(7)
28 = 7k
k =28/7
k = 4
Find output when input = n
Output = k(input)
= 4(n)
= 4n
Output = 4n
when input = n, Output = 4n

A hemispherical tank is filled with water and has a diameter of 15 feet. If water weighs 62.4 pounds per cubic foot, what is the total weight of the water in a full tank, to the nearest pound?
Answer:
55135 lbs (rounded to the nearest pound)
Step-by-step explanation:
diameter of tank = 15 ft
Radius = 15/2 =7.5
volume of hemisphere = 2/3 ×π× 7.5³=883.5729
total weight of water = 62.4 × 883.57 = 55134.768
55134.768 rounded to the nearest pound is 55135 lb

Use the figure above to determine the height of the pickle ball when it was
hit.
The height of the pickle ball when it was hit is = h = AB = 8.5 feet
The study of angles and of the angular relationships of planar and three-dimensional figures is known as trigonometry. The trigonometric functions (also called the circular functions) comprising trigonometry are the cosecant , cosine , cotangent , secant , sine , and tangent.
Applications of Trigonometry:
Measuring grounds lots, and fields,
Measuring ground surfaces,
Making building perpendicular and parallel,
Roof inclination and roof slopes,
Installing ceramic tiles and stones,
The height and width of the building.
Given in figure
(in feet)
ED = 3
BC = 34
BD = 22
AB = h = height of the pickle ball
Therefore DC = 34 - 22 = 12
In ΔEDC
Let ∠ECD = a
tan a = ED/DC
⇒ tan a = 3/12
⇒ tan a = 1/4 (1)
In ΔABC
∠ACB = a
tan a = h/34
⇒ 1/4 = h/34 (from 1)
⇒ h = 34/4
⇒ h = 8.5
Hence height of the pickle ball is 8.5 feet.

Suppose you know the total cost of the gas but do not know the price per gallon.
Explain how you would work backward to find the cost per gallon.
9514 1404 393
Answer:
price per gallon = (total cost)/(number of gallons)
Step-by-step explanation:
Price per gallon is found by dividing the price by the number of gallons:
price per gallon = (total cost)/(number of gallons)

I tried to solve, but ny answer did not make any sense do Im not sure how to ;-; Some help would be lovely :)
Answer:
x = 25
Step-by-step explanation:
A quadrilateral is inscribed in a circle, so it is a cyclic Quadrilateral.
Opposite angles of a cyclic quadrilateral are supplementary.
Therefore,
3x + 21y = 180°.....(1)
2x + 26y = 180°.....(2)
From equations (1) & (2)
3x + 21 y = 2x + 26y
3x - 2y = 26y - 21y
x = 5y
y = 1/5 x
Plug y = 1/5 x in equation (1)
3x + 21*1/5x = 180
15x + 21x = 180*5
(Multiplying both sides by 5)
36x = 900
x = 900/36
x = 25

In the following diagram overline DE || overline FG and overline KL perp FG. What is the measure of angle x?
Angle x = _____°
Given:
DE||FG and KL is perpendicular to FG.
To find:
The measure of angle x.
Solution:
If two lies intersect each other, then vertical opposite angles are equal.
[tex]m\angle ACB=63^\circ [/tex] (Vertically opposite angles)
[tex]m\angle BAC=x^\circ [/tex] (Vertically opposite angles)
KL is perpendicular to FG.
[tex]m\angle ABC=90^\circ[/tex]
According to the angle sum property, the sum of all interior angles of a triangle is 180 degrees.
In triangle ABC,
[tex]m\angle ABC+m\angle BAC+m\angle ACB=180^\circ[/tex]
[tex]90^\circ+x^\circ+63^\circ=180^\circ[/tex]
[tex]x^\circ+153^\circ=180^\circ[/tex]
[tex]x^\circ=180^\circ-153^\circ[/tex]
[tex]x^\circ=27^\circ[/tex]
Therefore, the measure of angle x is 27 degrees.
Above are two different models of the same triangle. If the area of the model on the left is 24 sq cm, what is the area of the model on the right?
The area of the model on the right = area of model on the left × 3² = 216 sq. cm.
What is a Model?A model represents a real object on a drawing paper.
Given that the model is triangular in shape, the model on the right is 3 times the model on the left.
Therefore, area of model on the left = area of model on the left × 3².
Area of model on the left = 24 × 9
Area of model on the left = 216 sq. cm.
