1.)log base 16 0.25
2.)log base 7 ¹/7
3.)log base 4 ⅛

Answers

Answer 1

Answer:

-1/2 , -1, -3/2

Step-by-step explanation:

1.)log base 16 1/4

log base 16 [tex]4 ^{-1 }[/tex] =x

[tex]16 ^{x} = 1/4[/tex]

x = -1/2

2.)log base 7 ¹/7

log base 7  [tex]7^{-1}[/tex] = x

7^x = 7^-1

x = -1

3.)log base 4 ⅛

4^x = 1/8

[tex]2^{2x} = 2^{-3}[/tex]

2x = -3

x = -3/2

Answer 2

Answer:

Step-by-step explanation:

1. Let a = log16 0.25, then:

0.25 = 16 ^ a = 16^-0.5

So the answer is -0.5.

2. log7 1/7

1/7 = 7^-1

Answer is -1.

3.  log4 1/8

1/8 = 4^(-1.5)

Answer is -1.5

7. Is 5.787787778... a rational or irrational number?
Explain.

Answers

Answer:

Rational ...................

Step-by-step explanation:

A rational number is a number that can be express as the ratio of two integers. A number that cannot be expressed that way is irrational. For example, one third in decimal form is 0.33333333333333 (the threes go on forever). However, one third can be express as 1 divided by 3, and since 1 and 3 are both integers, one third is a rational number

Mrs. Jim earned $40.00 for selling tacos, and she spent $9.75 for supplies. The next day, she earned $35.00 in taco sales and she spent $12.50 for supplies. How much did Mrs. Jim earn and how much did she spend?

a
She earned $15 and she spent $2.75
b
She earned $22.25 and she spent $75
c
She earned $75 and she spent $22.25
d
She earned $75 and spent $23.75

Answers

The answer is C. She earned $75 and spent $22.25

We can take our totals that were earned before she started spending and combine them. On concurrent days she received a total of $75. She got $40 one day and $35 the next. In between those days she spent, $9.75 and $12.50. She spent a total of $22.25. Once again making the answer option C

find the value of x and y​

Answers

Answer:

x=11

y=3

Step-by-step explanation:

(9x+25)=(13x-19)

9x+25 = 13x−19

9x+25-25 = 13x−19-25

9x=13x-44

9x-13x=13x-44-13x

-4x= -44

x=11

y= 180-(9x+25)

y= 180-(99+25)

y= 180-124 = 56

y= 56-5 = 51

y= 51/17

during the movie fundraising event the concession stand at the auditorium sells popcorn fruit and drinks the price of a box of popcorn is 0.50 more than

Answers

Using the information in the exercise to develop the system of equations and using the substitution method, the following answers are found:

The system of the linear equations is P = F + 0.50, 2D = 3F - 0.50, and 2P + F + 3D = 7.75, where P = The price of a box of popcorn, D = The price of a drink, and F = The price of a piece of fruit. By other hand, the price of each item is: Popcorn = $1.50, Drink = $1.25, and Fruit = $1.

Solution of the system of equations by the Substitution Method.

Taking into account the information given in the exercise, we can write the next equations:

P = F + 0.502D = 3F - 0.502P + F + 3D = 7.75

Where:

P = The price of a box of popcorn.D = The price of a drink.F = The price of a piece of fruit.

Since all equations have the variable F, we are going to use it as a key variable to represent the other variables in terms of F.

In the first equation we should not do anything, since P is in terms of F, in the second case the variable D is also in terms of F, but we need to find the value of just D, by this:

2D = 3F - 0.50D = (3F - 0.50) / 2D = 1.5F - 0.25

We proceed to substitute the first and second equations in the third equation:

2P + F + 3D = 7.752 (F + 0.50) + F + 3 (1.5F - 0.25) = 7.75

And we solve for the variable F:

2F + 1 + F + 4.5F - 0.75 = 7.757.5F + 0.25 = 7.757.5F = 7.75 - 0.257.5F = 7.5F = 7.5 / 7.5F = 1

Now, we can solve for the variable D with the second equation:

2D = 3F - 0.502D = 3 * (1) - 0.502D = 3 - 0.502D = 2.5D = 2.5 / 2D = 1.25

Finally, we can solve for the variable P with the first equation:

P = F + 0.50P = 1 + 0.50P = 1.50

So, we have the price of each item:

Popcorn = 1.50Drink = 1.25Fruit = 1
