Step-by-step explanation:

The radius of sphere is r = 4 cm.

Substitute the value in the formula to determine the surface area of sphere.

So answer is S.A = 201.1

The first number is 8.33 percent more than the second number.

Let m be the first number, n be the second number and p be the third number.

Two numbers are respectively twenty percent and ten percent more than a third number.

m = (100 + 20)% of p

m = 120 percent of p

m = 120 % of p

m = (120 / 100) × p

m = 1.2 p

And the second number would be,

n = (100 + 10)% of p

n = 110 percent of p

n = (110 / 100) × p

n = 1.1 p

We need to find by how much number the first number more than the second.

Consider the difference,

1.2 p - 1.1p = 0.1 p

So the required percentage noting but the difference is what percent of the first number.

(0.1 p / 1.2 p) × 100 = 8.33%

Therefore, the first number is 8.33 percent more than the second number.

Answer:

the answer has to be b

Step-by-step explanation:

The equation of the line perpendicular to the line −7x+2y=3 having the same y-intercept as 9x+3y=−2 is  y = - 2 / 7x - 2 / 3

The equation of a line can be represented as follows:

y = mx + b

where

Therefore, the equation of the line is perpendicular to  −7x+2y=3.

−7x+2y=3

2y = 7x + 3

y = 7 / 2 x + 3 / 2

Perpendicular lines follows the rule below:

m₁ m₂ = -1

7 / 2 m₂ = -1

7m₂ = -2

m₂ = - 2 / 7

Therefore, the equation of the line also haver the same y-intercept as

9x + 3y = −2.

3y = - 9x  - 2

y = -3x - 2  /3

The y-intercept of the equation is - 2 / 3.

Hence

the equation of the line is y = - 2 / 7x - 2 / 3

answer:

the y-intercept is 15 which is the initial total depth of the snow at t=0 hours.

The rate of melting is 1.5inches per hour. It will take 10 hours at the melting rate given of 1.5 to melt all the snow.

Step-by-step explanation:

the y-intercept is 15, and it might mean that the total depth of the snow is 15 inches.

The rate of melting is 1.5inches per hour.

At time = 0, S=15 - 1.5t = 15 - 1.5(0) = 15 inches to start

At time = 10, S=15 - 1.5t = 15 - 1.5(10) = 0 inches; meaning all snow has melted and it took 10 hours.

The unknown angles of the triangle and trapezium are as follows:

A triangle is a polygon with three sides.

The sum of angles in a triangle is 180 degrees.

Therefore, angle 1 can be found as follows:

∠1 = 180 - 40 - 30

∠1 = 180 - 70

∠1 = 110 degrees.

Therefore, angle 2 can be found as follows:

∠2 = 180 - 40 - 40 - 30 - 30

∠2 = 180 - 80 - 60

∠2 = 180 - 140

∠2 = 40 degrees.

A quadrilateral is a polygon with 4 sides. The sum of angles in a quadrilateral is 360 degrees.

Therefore, the triangle in the trapezium is an isosceles triangle. The base angles are equal.

Hence,

∠1 = 180 - 30 - 30

∠1 = 180 - 60

∠1 = 120 degrees

Sum of angles in the same transversal is supplementary.

Therefore,

90 + 30 + ∠2 = 180

∠2 = 180 - 120

∠2 = 60 degrees

If Zeke learned that he could earn another $2000 a year if he become fluent in Spanish and he intended to learn the language and work another 10 years at that job, then the amount is learning Spanish worth to him is $20000

The extra amount he could make if he learn Spanish = $2000

The number of years he works = 10 years

To find the extra amount, we have to use multiplication

The extra amount he could make if he learn Spanish = The extra amount he could make if he learn Spanish × The number of years he works

Substitute the values in the equation

= 2000×10

Multiply it

= $20000

Step-by-step explanation:

       We can look at the values given in the equation to graph it.

➜ The -3 shows the line will intercept the y-axis at -3.

➜ The equation has a slope of -4, so for everyone right we move four down.

y = 1 / 3 x + 5 is the linear equation for the first table.

The system of equations' answer is (3, 6).

A linear equation is an algebraic equation of the form y= mx+b, where m is the slope and b is the y-intercept, and only a constant and a first-order (linear) term are included. The previous equation, which has the variables y and x, is sometimes referred to as a "linear equation with two variables."

based on the available facts;

Equation of a point slope:

y = mx + b,

where m = slope and b = y-intercept

As a result, the equation for the second table is y = - 1 /3 x + 7.

With the help of the table's (0, 5)(3, 6) values, the equation for the first table may be solved. Therefore,

m = 6 - 5 / 3 - 0 = 1 / 3

let's find b using (0, 5)

5 = 1 / 3(0) + b

b = 5

Therefore, the equation of the first table is as follows:

y = 1 / 3 x + 5

The solution to the system of equation can be calculated as follows:

y + 1 /3 x  = 7

y - 1 / 3 x  = 5

2y = 12

y = 12 / 2

y = 6

6 - 1 / 3 x = 5

- 1 / 3 x = 5 - 6

- 1 / 3 x = - 1

x = 3

Therefore, the solution to the system of equation is (3, 6)

Answer:

13 ⅓.

Step-by-step explanation:

The area of a rectangle is given by

Area = Length × Breadth

Length = 2 7/9 = 25/9 and breadth = 4 4/5 = 24/5

.: Area = 25/9 × 24/5 = 600/45 (15 can go to both the numerator and denominator)

We have 40/3 but to convert it to a mixed fraction we get 13 ⅓ as your area.

The equation of the line will be equal to 3y = -x + 21.

A line may be defined as the straight figure drawn which has no end points. The equation of a line can be written in slope intercept form as y = mx + c where m is the slope of line, c is y intercept an x and y are independent and dependent variables. If a point (x₁, y₁) is given then equation of line is (y - y₁) = m (x - x₁). The slope of line which is perpendicular to a given line having slope m is equal to -1/m.

Now, equation of line is y = 3x + 3. If we compare with slope intercept form then, m = 3. Now, slope of line perpendicular to this line is equal to -1/3. Now, equation of line passing through point (-6, 9) is given as

(y - 9) = -1/3 (x + 6)

3y - 27 = -x - 6

=> 3y = -x + 21 which is the required equation of line.
