6/8 red 2/8 yellow

6/8 = 0.75

0.75 X 100 = 75%

12.5 Step-by-step explanation: My friend helped me

The length of Kelly's old snowboard is 125 cm long.

Suppose the value of which a thing is expressed in percentage is "a'

Suppose the percent that considered thing is of "a" is b%

Then since percent shows per 100 (since cent means 100), thus we will first divide the whole part in 100 parts and then we multiply it with b so that we collect b items per 100 items(that is exactly what b per cent means).

Thus, that thing in number is

[tex]\dfrac{a}{100} \times b[/tex]

For this case, let we suppose that:

x = length of Kelly's old snowboard (in cm)

Then, as we know that: new snowboard is 120% longer than her old snowboard, thus:

[tex]\dfrac{x}{100} \times 120 = \text{Length of new snowboard} = 150[/tex]

or

[tex]\dfrac{x}{100} \times 120 = 150\\\\\text{Multiplying 100/120 on both the sides}\\\\x \times \dfrac{120}{100} \times \dfrac{100}{120}= 150 \times \dfrac{100}{120}\\\\x \times 1 = x = \dfrac{150 \times 100}{120}\\\\x = \dfrac{15000}{120} = 125 \: \rm cm[/tex]

Thus, the length of Kelly's old snowboard is 150 cm long.

Answer:

1.625²

Step-by-step explanation!

1.625 x 1.625 is just 1.625 two times. So you add a 2 on the top which represents the number. You can write 1.625² instead of putting 1.625 x 1.625.  

1.625 x 1.625 can be written in exponential form as [tex]1.625^2[/tex]

Given :

The given expression is 1.625 x 1.625 . we need to write it in exponential form

The exponent is in the form of [tex]b^x[/tex], where 'b' is the base and 'x' is the exponent

base is the number and x is the exponent that is repeating number of times

For example , [tex]2 \cdot 2 \cdot 2 = 2^3[/tex]

where 2 is the base and 2 is occurring three times

so exponent is 3

1.625 x 1.625 can be written in exponential form as [tex]1.625^2[/tex]

Answer: She made 5 liters of punch for a lunch.

Step-by-step explanation:

We know that,

1 liter = 1000 milliliters

Then, 1 milliliter = [tex]\dfrac{1}{1000}[/tex] liters

We are given that,

Mr. Peters made 5000 milliliters of fruit punch for a lunch.

i.e. in liters, it will be [tex]\dfrac{5000}{1000}[/tex] liters.

i.e. in liters, it will be 5 liters.

i.e. She made 5 liters of fruit punch for a lunch.

Hence, she made 5 liters of fruit punch for a lunch.

Step-by-step explanation:

Lookin at the graph we see P = - 4

If Q has to be 6 and a half away from P then

  it can be towards the negative side at -4+(-6 and a half) = - 10 1/2 (not an option                given)

and

  it can be towards the positive side -4 + (6 and  a half) = 2 1/2 (C)

Options :

A. The initial number of bacteria is 7.

B. The initial of bacteria decreases at a rate of 93% each day.

C. The number of bacteria increases at a rate of 7% each day.

D. The number of bacteria at the end of one day is 360.

Answer:

C. The number of bacteria increases at a rate of 7% each day.

Step-by-step explanation:

Given the function :

f(x)=360(1.07)^x ; Number of bacteria in sample at the end of x days :

The function above represents an exponential growth function :

With the general form ; Ab^x

Where A = initial amount ;

b = growth rate

x = time

For the function :

A = initial amount of bacteria = 360

b = growth rate = (1 + r) = 1.07

If ; (1 + r) = 1.07 ; we can solve for r to obtain the daily growth rate ;

1 + r = 1.07

r = 1.07 - 1

r = 0.07

r as a percentage ;

0.07 * 100% = 7%

Answer:

OB

because domain is all X values that satisfy graph. And on graph X has all +ve values going to infinity.

When the Function g is defined as g(x) = 2f(x – 4) + 3 so the domain of the function g is OB. {x|0 < x <♾}.

Since the Function g is defined as g(x) = 2f(x – 4) + 3

So here OB should be considered as the domain of the all x values should satisfied the graph. Also, on graph X it contains the positive values that goes to infinity.

Hence, When the Function g is defined as g(x) = 2f(x – 4) + 3 so the domain of the function g is OB. {x|0 < x <♾}.

Step-by-step explanation:

Given that the set of data collected has an extreme value (24), a Median measure of center is more appropriate than a Mean measure.

We sort the same data collected in increasing order:

{0, 1, 2, 4, 4, 5, 5, 24}

There are 8 elements inside the set, so we check the 4th and 5th elements (closest to the center), which are 4 and 4.

Since they are equal, the Median is 4.

Our answer is Median; 4.

Answer:

y intercept is 6

Step-by-step explanation:

Given:

[tex]f(x) = 2(5^x) + 4[/tex]

Required:

Determine the y intercept

To do this, we simply set x to 0

Substitute 0 for x in [tex]f(x) = 2(5^x) + 4[/tex]

[tex]f(0) = 2(5^0) + 4[/tex]

Evaluate the exponent, [tex]5^0[/tex]

[tex]f(0) = 2(1) + 4[/tex]

Open bracket

[tex]f(0) = 2 + 4[/tex]

[tex]f(0) = 6[/tex]

Hence, the y intercept is 6
