Step-by-step explanation:

Given:

The ratio of the amount of money Kate has to that of Nora is 3 : 5.

After Nora gives $150 to Kate, the ratio of the amount of money Kate has to that of Nora becomes 7 : 9.

To find:

The sum of money Kate had initially.

Solution:

Let the initial amount of money Kate and Nora have are 3x and 5x respectively.

After Nora gives $150 to Kate, the ratio of the amount of money Kate has to that of Nora becomes 7 : 9.

The amount of Kate = 3x+150

The amount of Nora = 5x-150

Now,

[tex]\dfrac{3x+150}{5x-150}=\dfrac{7}{9}[/tex]

[tex]9(3x+150)=7(5x-150)[/tex]

[tex]27x+1350=35x-1050[/tex]

[tex]1350+1050=35x-27x[/tex]

[tex]2400=8x[/tex]

Divide both sides by 8.

[tex]300=x[/tex]

Putting x=300 in 3x, to get the amount of money Kate has initially.

[tex]3(300)=900[/tex]

Therefore, the Kate initially had $900.

Step-by-step explanation:

Answer:

20 years

Step-by-step explanation:

Given the ratio of their ages = 5 : 4 = 5x : 4x ( x is a multiplier )

Then in 5 years

5x + 5 : 4x + 5 = 6 : 5 , that is

[tex]\frac{5x+5}{4x+5}[/tex] = [tex]\frac{6}{5}[/tex] ( cross- multiply )

5(5x + 5) = 6(4x + 5) ← distribute parenthesis on both sides

25x + 25 = 24x + 30 ( subtract 24x from both sides )

x + 25 = 30 ( subtract 25 from both sides )

x = 5

Thus

Kiran's age is 4x = 4 × 5 = 20

Right Triangles

A right triangle is a special triangle that has an interior angle of 90°.

In right triangles, Pythagora's Theorem is satisfied:

[tex]c^2=a^2+b^2[/tex]

Where c is the hypotenuse (longest side) of the triangle, and a and b are the legs or the smaller sides.

The slide can be thought of as a right triangle whose hypotenuse is the slide itself and the legs are the height of the ladder and distance between the foot of the ladder and the end of the slide.

So we have:

[tex]c^2=22^2+10^2[/tex]

[tex]c^2=484+100=584[/tex]

[tex]c=\sqrt{584}[/tex]

c = 24.17 feet

Answer:

We conclude that the equation of this line in the slope-intercept form will be:

Step-by-step explanation:

We know that the slope-intercept form of the line equation is

[tex]y=mx+b[/tex]

where m is the slope and b is the y-intercept.

Given the equation

[tex]3z +y=2[/tex]

Writing the equation in the slope-intercept form of the line equation by simplifying it

subtracting 3z from both sides

[tex]3z+y-3z = -3z+2[/tex]

[tex]y = -3z+2[/tex]

Therefore, we conclude that the equation of this line in the slope-intercept form will be:

Answer:

-2

Step-by-step explanation:

f(t) = t^2 – 2t – 2

To find f(0), replace t with 0 in the expression and evaluate the expression.

f(0) = 0^2 – 2(0) – 2

f(0) = -2

0 = t

We know this because 0 replaced t in the parenthesis next to F !

The question is just asking you to plug in 0 where ever t is!

Let's do it

[tex]f(0) = 0^{2} - 2(0) - 2[/tex]

solve

[tex]0^{2} = 0 \\2 ( 0 ) = 0[/tex]

so, this is what we have left!

[tex]f(0) = 0 - 0 - 2[/tex]

We have our answer!

[tex]f (0) = -2[/tex]

Note: Its equilateral not equitorial triangle .

Given:

The statement is "An equilateral triangle has 3 medians".

To find:

Whether the given statement is true or false.

Solution:

Median of a triangle connected the vertex and midpoint of opposite side of the triangle.

We know that that every triangle has three medians.

In case of equilateral triangle, all sides and angles are equal and median is the height of the triangle.

So, an equilateral triangle has 3 medians.

Therefore, the given statement is true.

Answer:

The first term is 3 and the common difference is 2

Step-by-step explanation:

The formula of the sum of the nth term of the arithmetic sequence is

[tex]S_{n}=\frac{n}{2}[2a+(n-1)d][/tex], where

∵ The sum of the first five terms of an arithmetic sequence is 35

∴ [tex]S_{5}[/tex] = 35

→ Substitute The values of n and S in the rule above

∵ 35 = [tex]\frac{5}{2}[2a+(5-1)d][/tex]

∴ 35 = [tex]\frac{5}{2}[2a+4d][/tex]

→ Simplify the right side

∴ 35 = 5a + 10d

→ Switch the two sides

∴ 5a + 10d = 35 ⇒ (1)

∵ The sum of the next five terms is 85

→ To find the sum of the first 10 terms add 85 to [tex]S_{5}[/tex]

∴ [tex]S_{10}[/tex] = 35 + 85 = 120

→ Substitute The values of n and S in the rule above

∵ 120 = [tex]\frac{10}{2}[2a+(10-1)d][/tex]

∴ 120 = 5[2a + 9d]

→ Simplify the right side

∴ 120 = 10a + 45d

→ Switch the two sides

∴ 10a + 45d = 120 ⇒ (2)

Now we have a system of equations to solve it and find a and d

→ Multiply equation (1) by -2

∵ -2(5a) + -2(10d) = -2(35)

∴ -10a + -20d = -70 ⇒ (3)

→ Add equations (2) and (3)

∵ (10a + -10a) + (45d + -20d) = (120 + -70)

∴ 25d = 50

→ Divide both sides by 25 to find d

∴ d = 2

→ To find a substitute d in equation (1) by 2

∵ 5a + 10(2) = 35

∴ 5a + 20 = 35

→ Subtract 20 from both sides

∵ 5a + 20 - 20 = 35 - 20

∴ 5a = 15

→ Divide both sides by 5

∴ a = 3

∴ The first term is 3 and the common difference is 2

12 - e < -2

- e < -2 - 12       Move 12 to subtract.

- e < - 14

e > 14     When the coefficient is in negative. Moving the negative as changing the sign of Inequality to opposite.

Therefore, the answer is e > 14

The average rate of change for  f(x)=3x²-3 from x =1 to x=2 is 6.

What is the average rate of change?

The average rate of change is the rate at which the value of function changed per unit  of independent variable over a given interval. Let f(x) be a function and value of x changes from x₁ to x₂ then rate of change of f(x) over the interval (x₁, x₂ ) is

[f(x₂)-f(x₁)]/[x₂-x₁]

Average rate of change = [f(x₂)-f(x₁)]/[x₂-x₁]

Given function is

f(x)=3x²+3x-6

x changes from 1 to 2

Then average rate of change for f(x) is [tex]\frac{f(2)-f(1))}{2-1}[/tex]

[tex]f(2)=2^{2} +3(2)-6=4+6-6\\\\f(2)=4\\f(1)=1^{2}+3(1)-6 =1+3-6\\f(1)=-2[/tex]

Average rate of change for f(x) is

[tex]\frac{f(2)-f(1))}{2-1}=\frac{4-(-2)}{2-1}\\ =\frac{6}{1}[/tex]
