The height of the cone is 1.6 ft.
What is cone?A right circular cone is one whose axis is perpendicular to the plane of the base. We can generate a right cone by revolving a right triangle about one of its legs.
Given that, a right circular cone has a volume of 15 cubic feet and a radius of 3 feet, we need to find the height of the cone,
Volume of the cone = π × radius² × height / 3
15 × 3 = 3.14 × 3² × height
Height = 45 / 3.14 × 9
Height = 1.60
Hence, the height of the cone is 1.6 ft.

Step-by-step explanation:
Solve the following simulataneous equations using an algebraic method (not graphical).
2x + 5y = 0
3x-4y = 23
Given:
The equations are
[tex]2x+5y=0[/tex]
[tex]3x-4y=23[/tex]
To find:
The solution of given system of equations.
Solution:
We have,
[tex]2x+5y=0[/tex] ...(i)
[tex]3x-4y=23[/tex] ...(ii)
From (i), we get
[tex]2x=-5y[/tex]
[tex]x=-\dfrac{5y}{2}[/tex] ...(iii)
Putting this value in (ii), we get
[tex]3(-\dfrac{5y}{2})-4y=23[/tex]
[tex]-\dfrac{15y}{2}-4y=23[/tex]
[tex]\dfrac{-15y-8y}{2}=23[/tex]
[tex]-23y=2\times 23[/tex]
[tex]y=\dfrac{46}{-23}[/tex]
[tex]y=-2[/tex]
Putting y=-2 in (iii), we get
[tex]x=-\dfrac{5(-2)}{2}[/tex]
[tex]x=-\dfrac{-10}{2}[/tex]
[tex]x=\dfrac{10}{2}[/tex]
[tex]x=5[/tex]

Answer:
The missing value of x in this arithmetic sequence is "1"
Step-by-step explanation:
Since this is an arithmetic sequence that means that when we get from one term to the next one we always add/substract the same number each time.
In our case each time we need to find the next term we just add 6 to the current term. For example, after 13 we have 19 which is essentially 13 + 6.
From this we know in order to get from x to 7 we added 6, now know this we can make an equation...
x + 6 = 7
And now we just solve it...
x + 6 = 7
x = 7 - 6
x = 1

The graph of y = f(x) is shown below. Find all values of x where f(x) = 0
Graphs are used to show the relationship between two variables (usually x and y). The values of x when [tex]f(x) = 0[/tex] are 2 and 8
The graph of y = f(x) is given
To get the values of x when [tex]f(x) = 0[/tex], we simply consider where the line of the graph crosses the x-axis.
The graph crosses the x-axis at:
[tex]x = 2[/tex]
[tex]x = 8[/tex]
This means that the values of x when [tex]f(x) = 0[/tex] are 2 and 8

Work out angle x 55°
Answer:
70°
Step-by-step explanation:
We know that the triangle is an iscoceles based on the 2 small lines drawn horizontally on 2 sides of the triangle.
We know that the base angles in an iscoceles triangle are the same, so the angle that has not been drawn is 55°.
55° + 55° = 110°
180° - 110° = 70° (180 comes from the entire triangle adding up to 180°)
You are trying to increase your monthly savings to buy a used car. Your boss allows you to work one hour of overtime at time-and-half 5 days per week. Your regular wage is $12.00 per hour. You want to save $3,000 for your car. Approximately how many weeks must you work with the extra hour per day to reach your goal?
Answer:
34 weeks
Step-by-step explanation:
As given,
Wage of 1 hour = $12
⇒1$ = [tex]\frac{1}{12}[/tex] hour
⇒$3000 = [tex]\frac{3000}{12}[/tex] = 250 hour
As given,
1 week = 5 days
And he works
[tex]1\frac{1}{2} = \frac{3}{2}[/tex] hour in 1 day
⇒5 days = 5×[tex]\frac{3}{2}[/tex] = [tex]\frac{15}{2}[/tex] hours
⇒1 week = [tex]\frac{15}{2}[/tex] hours
⇒1 hour = [tex]\frac{2}{15}[/tex] week
⇒250 hour = [tex]\frac{250 . 2}{15}[/tex] = 33.34 weeks ≈ 34 weeks
∴ we get
He has to Approximately work for 34 weeks with the extra hour per day to reach your goal.

The scale of the room design shows that 1" = 3 feet. How big is the actual room if the design shows a square that is 6 inches wide?
Answer:
arah is at a miniature exhibit. There is a model of a skyscraper. Underneath the model was a ratio. It said:
1 inch=30 feet.
If the model is 38 inches tall, how Sarah use this information to find the actual height of the skyscraper?
In this concept, you will learn how proportions are used to find actual and scale dimensions using a scale ratio.
Using Proportions to Find Dimensions
A scale is a ratio that shows the relationship between the representation of an object and the real measurement of an object. Toy makers use scale ratios to make models of cars and airplanes that are proportional to the real thing. Architects use scale drawings to plan the design of buildings.
A scale drawing is a drawing that is used to represent and object that is too large to be drawn in its actual dimensions. If a drawing is to scale, you can use proportions to determine the actual dimensions of the scale drawing.
Let’s look at a scale drawing of a sculpture. In the drawing, the sculpture is 4 inches tall. The scale is 1 inch : 4 feet. It scale can be written as
1 in4 ft
(Note: Inch is abbreviated “in.” or with the double prime mark, ″. Foot/feet is abbreviated “ft” or with the single prime mark, ′.)
A drawing with this scale tells you that 1 inch on paper is equal to 4 feet in real life. If the drawing is 4 inches tall, use the scale to find the actual height of the sculpture.
First, create a proportion using equivalent ratios. Remember to write the corresponding units in the numerator and in the denominator. The actual height of the sculpture is represented by the variable x.
1 in.4 ft.=4 in.x ft.
Then, cross multiply and simplify the equation to find the value of x.
xx==4(4)16
The sculpture will be 16 feet tall.
Let’s make a scale drawing. Use the scale 1′′=2′. Draw a room that is 8′×12′.
First, write a proportion to find the measurement of the width.
1′′2′=x′′8′
Next, cross multiply and simplify the equation to find the value of x.
2x2xx===1(8)84
The drawing will be 4
What is an equation of the line that passes through the point (7,6) and (-2,-3)
Answer:
y=x-1
Step-by-step explanation:
m=(y2-y1)/(x2-x1)
m=(-3-6)/(-2-7)
m=-9/-9
m=1
y-y1=m(x-x1)
y-6=1(x-7)
y-6=x-7
y=x-7+6
y=x-1

Answer:
The left one does.

Maia's garden is made of rectangular regions, as shown below. She wants to cover her garden with plastic muluch to warm the soil. What is the area of the garden?
*check figure 1 for the diagram of the garden
Answer:
2,400 cm²
Step-by-step explanation:
The area of the garden has been decomposed into 3 rectangles, rectangles 1, 2, and 3 (see figure 2 in the attachment below).
To find the area of the garden, calculate the area of each of the 3 rectangles and sum them together.
Thus:
Rectangle 1:
Area = length × width = 20 × 20 = 400 cm²
Rectangle 2:
Area = length × width = 60 × 10 = 600 cm²
Rectangle 3:
Area = length × width = 70 × 20 = 1,400 cm²
✔️Area of the garden = 400 + 600 + 1,400 = 2,400 cm²
