The ratio of Elena's hair ties to Melanie At first is 32/8 divide by eight is 4:1

The new hair ties after Melanie gets 4 is 12 ,so the new ratio of Elena's hair ties to Melanie that is 32/12 divided by four will be 8:3

To combine two fractions into one fraction if they are being added / subtracted from each other, make it so they share the same denominator.  To do this, one way is to make [tex]\frac{1}{3}[/tex] have denominator [tex]3t[/tex], so multiply the top and bottom of the fraction by [tex]t[/tex]:

[tex]\frac{t+2}{3t} - \frac{t}{3t}[/tex]

and now you can just subtract the numerator.

[tex]= \frac{t+2 - t}{3t} = \frac{2}{3t}[/tex]

Answer:

$1680

Step-by-step explanation:

I = 5%

P = $1600

period = 1 year

$1600 + 15% = $1680

Answer:

$1680.

Step-by-step explanation:

The interest for 1 year = 1600 * 5%

= 1600 * 0.05

= $80.

So the new balance = old balance + interest

= 1600 + 80

= $1680.

You need to find which two perfect squares is the sqrt{18} between.

sqrt{16} is a perfect square = 4

sqrt{25} is a perfect square = 5.

We conclude the sqrt{18} lies between the sqrt{16} and sqrt{25}.

The graph of the line is shown below

From the question, we are to determine the graph of the line by plotting any two ordered pairs

First, we will find two ordered pairs on the line

y = -3x

When x = 1

y = -3x

y = -3(1)

y = -3

(1, -3)

When x = 2

y = -3x

y = -3(2)

y = -6

(2, -6)

Using the ordered pairs, the graph of the line is shown below

In scientific notation, the Motor Vehicle Deaths per capita for Ohio is 8.996 x 10⁻⁵.

Scientific notation, or the power-of-10 notation, is a mathematical system for expressing huge and small numbers so that they look simple.

A scientific notation of the number 'n' is expressed as a∗10^b. where 'a' is an integer such that 1 ≤ |a| <10. B is an integer that takes positive or negative values.

State         MV Deaths    Population

Indiana         693               6 million

Illinois            911              12.4 million

Ohio            1021               11.35 million

Michigan      871                9.9 million

Alaska           64               0.63 million

Motor Vehicle Deathers per capita for Ohio = 1,021/11,350,000

= 0.00008995594

= 0.00008996

= 8.996 x 10⁻⁵

Thus, the scientific notation of the Motor Vehicle Deaths per capita for Ohio is 8.996 x 10⁻⁵.

Answer:

Step-by-step explanation:​

The general equation of a circle is expressed as;

(x-a)² + (y - b)² = r² where;

(a, b) is the centre of the circle

r is the radius

Given

Centre (-8, 9) where a = -8, b = 9

radius r = 10

Substitute into the formula to get the required equation;

(x-(-8))² + (y - 9)² = 10²

(x+8))² + (y - 9)² = 10²

(x+8)² + (y - 9)² = 100

Hence the required equation is (x+8)² + (y - 9)² = 100

Answer: M(x) = -4*x^0 = -4

Step-by-step explanation:

A monomial is a polynomial with only a term.

We can write a random monomial as:

M(x) = a*x^n

Where n is a natural number.

Then we know that:

(-x^2 + 5*x - 1)*a*x^n = 4*x^2 - 20*x + 4

Solving the left side, we get:

-a*x^(2 + n) + a*5*x^(1 + n) - a*1*x^n = 4*x^2 - 20*x + 4

First, we can see that the powers of x do not change after multiplying by the monomial, this means that we must have n = 0. Then we have:

-a*x^2 + a*5*x - a = 4*x^2 - 20*x + 4

The terms with equal powers of x must be equal between them, this means that:

-a*x^2 = 4*x^2

a*5*x = -20*x

-a = 4

From the last equation, (we also could get the same by solving the first or second) we get that a = -4

Then the monomial will be:

M(x) = -4*x^0 = -4

Answer:

HL = 21

Step-by-step explanation:

HL is the midsegment of the trapezoid shown above. Thus, it follows that:

HL = (JK + GF)/2

JK = 12

GF = 2.5(JK) = 2.5(12) = 30

Plug in the values:

HL = (12 + 30)/2

HL = 42/2

HL = 21

Answer:

(x-2)^1/4=2 ---> 18

√x^2+7=4. ---> -3

^3√1-x=-1. ---> 2

Step-by-step explanation:

just did it on plato

The numerical expression [tex]\rm (x - 2)^{1/4} = 1[/tex], √x² + 7 = 4, and ∛(1 - x) = -1 are correctly matched with 18, -3, and 2.

Simplification is to make something easier to do or understand and to make something less complicated.

The expressions are given below.

[tex]\rm (x - 2)^{1/4} = 1[/tex], √x² + 7 = 4, and ∛(1 - x) = -1

Then By simplification, we have

x - 2 = 2⁴

    x = 16 + 2

    x = 18

√x² + 7 = 4

x + 7 = 4

x = -3

∛(1 - x) = -1

    1 - x = -1³

        x = 2

The numerical expression [tex]\rm (x - 2)^{1/4} = 1[/tex], √x² + 7 = 4, and ∛(1 - x) = -1 are correctly matched with 18, -3, and 2.

To avoid confusion in using the word "particle," one must state that a particle is an identifiable part of dust, a molecule, an atom, or an electron.  This means that particles form these elements.

Step-by-step explanation:

For example, atoms are made up of three particles: protons, neutrons and electrons.  These particles are each composed of even smaller particles known as quarks.  Since quarks cannot be broken down further, they are the smallest particles known to mankind.

The required quadratic function in the standard form is f(x) = -1.25 x² + 5x.

What is a quadratic equation ?

A quadratic equation is an equation which contains a single variable of degree 2 and its general form is ax² + bx + c = 0.

The x - intercepts of the quadratic equation are (-5, 0) and (0 , -8). That meant (x + 5) and (x -0) are two factors of quadratic equation.

f(x) = a (x + 5) (x - 0)

f(x) = ax² + 5x

The graph of quadratic equation passes through (4 , 0). So we need to substitute x = 4 , f(x) = 0 in equation 1.

0 = a × 4² + (5 × 4)

0 = a × 16 +20

a = -20/16

We know that quadratic equation is in form ax² + bx + c = 0.

f(x) = [tex]\frac{-20}{16}[/tex] × x² + 5x

f(x) = [tex]\frac{-5}{4}[/tex]x² + 5x

f(x) = -1.25 x² + 5x  

Therefore , the required quadratic function in the standard form is f(x) = -1.25 x² + 5x.
