Answer:

The area of cross-section is [tex]30inch^2[/tex]

Step-by-step explanation:

we are given that

a cone is cut by a plane that passes through its vertex and it’s vertex and is perpendicular to its base

So, cross -section will be right angled triangle

whose base will be along diameter of cone

so, base of triangle = diameter of cone =6 inch

base =6 inch

Height of triangle will be same as height of cone

so, height of triangle =10inch

now, we can find area

[tex]Area=\frac{1}{2}\times 6\times 10[/tex]

[tex]Area=30inch^2[/tex]

The area of the cross-section formed by the intersection is 9π square inches.

When a cone is cut by a plane passing through its vertex and perpendicular to its base, the resulting intersection is a triangle similar to the base of the cone.

Such that;

Using the properties of similar triangles, the triangle formed by the intersection is similar to the base of the cone.

The area of the cross-section formed by the intersection is the area of a circle with radius 3 inches:

Area = πr²

Area = π × 3²

Area = π × 9

Area = 9π square inches

60 minutes for the larger hose to fill the swimming pool by itself

Step-by-step explanation:

It is given that,

Working together, it takes two different sized hoses 20 minutes to fill a small swimming pool.

takes 30 minutes for the larger hose to fill the swimming pool by itself

Let x be the efficiency to fill the swimming pool by larger hose

and y be the efficiency to fill the swimming pool by larger hose

To find LCM of 20 and 30

LCM (20, 30) = 60

To find the efficiency

Let x be the efficiency to fill the swimming pool by larger hose

and y be the efficiency to fill the swimming pool by larger hose

x = 60/30 =2

x + y = 60 /20 = 3

Therefore efficiency of y = (x + y) - x =3 - 2 = 1

so, time taken to fill the swimming pool by small hose = 60/1 = 60 minutes

Answer:

The length of CX is 22 ft.

Step-by-step explanation:

Given information: In triangle ABC, F, G, and H are the midpoints of sides BC, CA, and AB respectively.

The medians FA, BG and CH intersect each other at point X.

According to the property of triangle, the intersection point of medians is called centroid and the centroid divides each median in 2:1.

Since X is centroid, therefore points X divides the median CH in 2:1, therefore we can say that CX:XH is 2:1.

It is given that the length of CX is 33.

[tex]CX=\frac{2}{3}CH[/tex]

[tex]CX=\frac{2}{3}\times 33[/tex]

Answer:

z = 123.9

Step-by-step explanation:

We can use trigonometric functions, because we have a right triangle.  We now the adjacent and opposite side of the angle we are interested in, so we can use the tan function.

tan 20 = opposite/ adjacent

tan 20 = 45.1/z

Multiply each side by z

z* tan 20 = 45.1 /z * z

z * tan 20 =45.1

Divide each side by tan 20

z = 45.1 / tan 20

z=123.9112316

To one decimal place,

z = 123.9

It will take 5 days for the 4 people working 6 hours a day to complete the kitchen remodel.

Let's calculate the total work hours required to complete the kitchen remodel and then determine how many days it will take for the 4 people working 6 hours a day to finish the job.

The estimated total work hours for one person to complete the remodel is 120 hours.

Total work hours required = 120 hours

Now, we have 4 people working on the job, and each person works 6 hours a day.

Total work hours per day with 4 people = 4 people * 6 hours/person = 24 hours

To find the number of days it will take to complete the job, we divide the total work hours required by the total work hours per day with 4 people:

Number of days = Total work hours required / Total work hours per day with 4 people

Number of days = 120 hours / 24 hours/day

Number of days = 5 days

It will take 5 days for the 4 people working 6 hours a day to complete the kitchen remodel.

10x-7y=-18

To solve by elimination, we pick a variable to eliminate, or get rid of.  I will multiply the first equation by -2 so we can get rid of x

-2( 5x+y)=9 *-2

-10x -2y = -18

Now we add this equation to the second equation

-10x -2y = -18

10x-7y=-18

Divide each side by -9

-9y/-9 = -36/-9

y =4

We still need to solve for x

Step-by-step explanation:

Final answer:

The painter can completely paint 11 apartments with 45 gallons of paint and will have 1 gallon of paint left over.

Explanation:

A painter uses 4 gallons of paint for each apartment. With 45 gallons of paint, you would first divide the total gallons of paint by the gallons needed per apartment to determine how many apartments can be painted completely. Since 45 gallons ÷ 4 gallons per apartment equals 11.25, the painter can only completely paint 11 apartments, because you can't partially paint an apartment. The fractional part, .25, represents the leftover paint. To find out how much paint is remaining, you would then multiply the fractional part by the amount of paint used for one apartment, which is 4 gallons. So, 0.25 × 4 gallons equals 1 gallon. Therefore, the painter will have 1 gallon of paint left over after painting 11 apartments.

When 18 is divided by 4, the quotient is 4 and the remainder is 2.

The division of 18 by 4, can be performed using long division or mental math. First, understand that 'dividend' is the number being divided (18), 'divisor' is what you divide by (4), 'quotient' is the result of the division and 'remainder' is what is left over.

Step 1: Divide 18 by 4. 4 fits into 18 four times (4 x 4 = 16).

Step 2: Subtract the 16 from 18 to find the remainder. 18 - 16 equals 2.

So, the quotient of 18 divided by 4 is 4 and the remainder is 2.
