write ____ as a single power of 7

Step-by-step explanation:

2 cups of sugar mix with 7 cups of water.

so, 2/2 = 1 cup of sugar mixes therefore with 7/2 = 3.5 cups of water.

and 5 cups of sugar (= 5×1 cups) mix with 5×3.5 = 17.5 cups of water.

not 21. not 28. it is 17.5 cups of water !

Answer: 22.5

Step-by-step explanation:

25% is [tex]\frac{1}{4}[/tex] of 100%

So, 90/4 = 22.5

Answer:

22.5

Step-by-step explanation:

10% of 90 is 9

Multiply that by 2 then you get 18.

Half of 10% will give you the remaining 5% which is 4.5

Then add 18 and 4.5 you 22.5

When t=0 and t=6s is the time at which the particle have a velocity of 25 m/s and t=3s is the time when acceleration is 0.

a vehicle's capacity to gain speed within a short time

Given s = t^4 − 4t^3 − 36t^2 + 25t

v=d/dt(s)=4t^3-12t^2-72t+25

the particle have a velocity of 25 m/s

So 4t^3-12t^2-72t+25=25

=4t^3-12t^2-72t

=4t(t^2-3t-18)=0

t=0 and

t^2-3t-18=0

(t+3)(t-6)=0

So t=0, t=-3 and t=6

As time>=0, So t=0 and t=6.

Now we required to find acceleration,

Accelaration=d/dt(v)

=d/dt(4t^3-12t^2-72t+25)

=12t^2-12t-72

t=12±√144-4(12)(-72)/24

t=12±60/24

t=12+60/24=3  and 12-60/24=-2

So t=3s

Therefore t=0 and t=6s is the time at which the particle have a velocity of 25 m/s and t=3s is the time when acceleration is 0.

Answer: (5, -6)

Step-by-step explanation:

I'm not really 100% sure if i can put in detail but this is the correct answer

The number of pounds of steak she buys is 0.82 pounds

From the question, we have the following parameters:

3.5 pounds of steak = $36.75

From the question, we understand that

Hannah spent $8.61 on steak

This means that

x pounds = $8.61

So, we have the following system of equations

3.5 pounds of steak = $36.75

x pounds = $8.61

Cross multiply in the above equation

So, we have

36.75 * x = 3.5 * 8.61

Divide both sides of the equation by 36.75

x = 3.5 * 8.61/36.75

Evaluate the quotient

x = 0.82

Hence, the number of pounds of steak she buys is 0.82 pounds

Explanation- Did the maths

Antonio will save $113.4 after calculating using mensuration and buying from Pets Galore instead of Healthy pets.

As per the question statement, Antonio needs to buy 150 pounds of dog food for the local dog shelter. Healthy Pets, sells dog food in 50-pound bags for $85.95 per bag and Pets Galore sells one bag for $48.15

We are supposed to calculate the amount of money saved by Antonio if he buys 150 pounds of dog food from Pets Galore instead of from Healthy Pets.

Using concept of mensuration,

Quantity of dog food in one bag = 50 pounds

Quantity required of dog food = 150 pounds

Therefore number of bags required = 150/50 = 3

Price of dog food at Pets Galore per bag = $48.15

Total money to be paid to Pets Galore for 3 bags = $48.15*3  = $144.45

Total money to be paid to Healthy Pets for 3 bags = $85.95*3 = $275.85

Therefore money saved = $275.85 - $144.45  = $113.4

The amount that would be in th IRA when he retires at age 65 is $21,932.15.

An annuity is a series of payment that is made over a period of time. In this question, the annuity is monthly which lasts for 47 years (65 - 18). An ordinary annuity is when the payments are made at the end of the period. An annuity due is when the payment is made at the beginning of the period.

The amount deposited increases by the amount you put in it every month and by the interest rate the account accrues. The account earns an APR, this means that interest would be compounded yearly.  

Total amount of deposits = amount deposited monthly x number of months in a year x number of years

$60 x 12 x 47 = 33,840

The formula that can be used to determine the future value of the account in 47 years is:

Monthly deposit x annuity factor

Annuity factor = {[(1+r)^n] - 1} / r

Where:

$60 x [{(1.00583)^564 - 1} / 0.07] = $21,932.15

Step-by-step explanation:

The words related to the mathematical operation of division are:

A division between two numbers tells us how many times the denominator can be fit into the numerator (the numerator is the number being divided by the denominator).

The "math word" used for divisions is "quotient"

The quotient between two numbers is equivalent to say the "outcome of the division between two numbers"

So that is one of the correct options.

Other correct option is "separate"

Like in the word problem example "3 friends separate evenly 9 candy between them". Here we have a division.

Similar, "cut" is also related to divisions.

The word problem "A piece of wire of 1 meter is cut into 3 pieces, how long is each one?"

AB and CD are congruent.

Step-by-step explanation:

Given points:

To determine if AB and CD are congruent, calculate the length of the two lines using the distance formula.

[tex]\boxed{\begin{minipage}{7.8 cm}\underline{Distance Formula}\\\\$d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$\\\\where $(x_1,y_1)$ and $(x_2,y_2)$ are the two endpoints.\end{minipage}}[/tex]

[tex]\begin{aligned}\implies AB & = \sqrt{(x_B-x_A)^2+(y_B-y_A)^2}\\& = \sqrt{(2-4)^2+(6-1)^2}\\& = \sqrt{(-2)^2+(5)^2}\\& = \sqrt{4+25}\\& = \sqrt{29}\end{aligned}[/tex]

[tex]\begin{aligned}\implies CD & = \sqrt{(x_D-x_C)^2+(y_D-y_C)^2}\\& = \sqrt{(-4-(-2))^2+(-3-2)^2\\& = \sqrt{(-2)^2+(-5)^2}\\& = \sqrt{4+25}\\& = \sqrt{29}\end{aligned}[/tex]

Therefore, as AB = CD, we can conclude that AB and CD are congruent.

These are our two tables of values for the following functions using the integers from -4 to 4.

A function is defined as a relation between a set of inputs having one output each. function is a relationship between inputs where each input is related to exactly one output. Every function has a domain and codomain or range. A function is generally denoted by f(x) where x is the input.

Given:

The given functions using the integers from -4 to 4 are

a. F(x)=6/x-2b.

r(x)=6x+12/x²-4

According to given question we have

f(x) = 6/x - 2

Now we just need to evaluate the function in all the given points:

a) f(x) = 6/x - 2

Now we can put the value

f(-4) = 6/(-4) - 2 =  -3/2 - 4/2 = -7/2

f(-3) = 6/-3 - 2 = -4

f(-2) = 6/-2 - 2 = -5

f(-1) = 6/-1 - 2 = -8

f(0) is undefined

f(1) = 6/1 - 2 = 4

f(2) = 6/2 - 2 = 1

f(3) = 6/3 - 2 = 0

f(4) = 6/4 - 2 = -1/2

b. r(x)=6x+12/x²-4

Now we can put the value

r(-4) = 6(-4)+12/(-4)²-4=-27.25

r(-3) = 6(-3)+12/(-3)²-4=-20.66

r(-2) = 6(-2)+12/(-2)²-4=-13

r(-1) = 6(-1)+12/(-1)²-4= 2

r(0) = 6(0)+12/(0)²-4= ∞

r(1) = 6(1)+12/(1)²-4 =14

r(2) = 6(2)+12/(2)²-4=11

r(3) = 6(3)+12/(3)²-4 =15.33

r(4) = 6(4)+12/(4)²-4=20.75

Linear equations are equations that have constant average rates of change. Note that the constant average rates of change can also be regarded as the slope or the gradient

The linear equation is given as

g(x) = 3x - 2

To determine the solution to the linear equation, we set the value of x to some values

say x = 0, 1 and 2

Substitute x = 0, 1 and 2 in g(x) = 3x - 2

g(0) = 3(0) - 2 = -2

g(1) = 3(1) - 2 = 1
