4/9 x 15/8 answer the question and give the simplest form.

Answer:

n - 8 >= 10

n minus 8 is greater than or equal to 10

Eight less than a number " n" , is at least 10.

The inequality for this condition can be represented as

[tex]\bold{ { n-8\geq 10}}\\[/tex]

Hence option (2) is correct

To find out the expression for this inequality  let us consider that the number be ''n"

Since the actual number in the question is less than this number [tex]\rm n[/tex] by [tex]8[/tex] hence let the new number be [tex]\rm N[/tex]

From the given condition in the statement  we can write that

[tex]\rm N = n-8[/tex]

According to the condition given in the statement  we can write that

The value of [tex]\rm N[/tex] is at least  10. This means  the minimum value for [tex]\rm N[/tex] is 10.

This signifies that N can be any number with minimum value 10.

So the inequality for this condition can be represented as

[tex]\rm\bold{ { N\geq 10}}\\\bold{ { n-8\geq 10}}\\[/tex]

Hence option (2) is correct

Answer:

[tex]y = 3(7)^x[/tex]

Step-by-step explanation:

Given

[tex](x_1,y_1) = (0,3)[/tex]

[tex](x_2,y_2) = (4,7203)[/tex]

Required

Determine an exponential function

Substitute 0 for x and 3 for y in [tex]y=ab^x[/tex]

[tex]3 = ab^0[/tex]

[tex]3 = a*1[/tex]

[tex]3 = a[/tex]

[tex]a = 3[/tex]

Substitute 4 for x and 7203 for y in [tex]y=ab^x[/tex]

[tex]7203= ab^4[/tex]

Substitute 3 for a

[tex]7203= 3*b^4[/tex]

Divide both sides by 3

[tex]2401= b^4[/tex]

Take 4th root of both sides

[tex]\sqrt[4]{2401} = b[/tex]

[tex]7 = b[/tex]

[tex]b = 7[/tex]

Substitute 3 for a and 7 for b in [tex]y=ab^x[/tex]

[tex]y = 3(7)^x[/tex]

4x+y=17;4x−3y=−3

Step: Solve4x+y=17for y:

4x+y+−4x=17+−4x(Add -4x to both sides)

y=−4x+17

Step: Substitute−4x+17foryin4x−3y=−3:

4x−3y=−3

4x−3(−4x+17)=−3

16x−51=−3(Simplify both sides of the equation)

16x−51+51=−3+51(Add 51 to both sides)

16x=48

16/x = 48/16

(Divide both sides by 16)

x=3

Step: Substitute 3 for x in y=−4x+17:

y=−4x+17

y=(−4)(3)+17

y=5(Simplify both sides of the equation)

Answer:

$ 900

Step-by-step explanation:

Simple interest = Principle * Time * Rate / 100

Now by substituting :

The measure of the angle from the given figure is 85°.

In the given figure, the measure of angle is given.

An angle is formed when two straight lines or rays meet at a common endpoint. The common point of contact is called the vertex of an angle.

In the given figure, the ray is between 90° and 80°

So, the measure of the angle is 85°

Hence, the measure of the angle from the given figure is 85°.

Answer:

5

Step-by-step explanation:

Hi,

find the x- and y-intercepts:

10x + 4y = 20

finding x-intercept when y = 0

10x = 20  

x = 2  Pt(2,0) the x intercept

finding y-intercept when x = 0

4y = 20

y = 5  Pt(0,5) the y intercept

Answer:

∠P = 110º

∠Q = 70º

Step-by-step explanation:

we know that a straight line is equal to 180º and since we already have one angle (70º) all we have to do is subtract 70 from 180.

180 - 70 = 110º

we also know that vertical angles are congruent (the same) so we're already given angle q.

Answer:

Step-by-step explanation:

If a coordinate point (x, y) is dilated by a factor k, then the resulting coordinate will be (kx, ky)

Given the coordinate (4,1), if this coordinate is dilated by a factor of 2 then the new coordinate points will be at (2(4), 2(1))

New point = (8, 2)

Hence  x-coordinate of one of the the end point of the dilated segment is 8

9=-5b-23

Answer:

65.974 Square-miles

Step-by-step explanation:

We do 3.14*2^2=12.566

We then do 3.14*5^2=78.54

78.54-12.566=65.974

The change in the area of the circular oil spill is given by the equation

A = 65.973 miles²

A circle is a closed two-dimensional figure in which the set of all the points in the plane is equidistant from a given point called “center”. Every line that passes through the circle forms the line of reflection symmetry. Also, the circle has rotational symmetry around the center for every angle

The perimeter of circle = 2πr

The area of the circle = πr²

where r is the radius of the circle

The standard form of a circle is

( x - h )² + ( y - k )² = r²,

where r is the radius of the circle and (h,k) is the center of the circle

Given data ,

Let the change in area of circular oil spill be A

Now , the equation will be

The initial radius of the circular oil spill r = 2 miles

The increased radius of the circular oil spill R = r + 3

R = 5 miles

Now , the initial area of the circular oil spill = πr²

Substituting the values in the equation , we get

The initial area of the circular oil spill = 4π miles²

Now ,

The increased area of the circular oil spill = πR²

Substituting the values in the equation , we get

The increased area of the circular oil spill = 25π miles²

And , change in area of circular oil spill A = 25π miles² - 4π miles²

On simplifying the equation , we get

The change in area of circular oil spill A = 21π miles²

The change in area of circular oil spill A = 65.973 miles²

Therefore , the value of A is 65.973 miles²

Hence , the change in circular area is 65.973 miles²
