Answers

Answer:


8.50x + 6.00y < 60 and y > 3.

Please consider the complete question.

Amy's restaurant has a budget of at most $60 to spend this month on gourmet coffee. All international blends cost $8.50 per package and all house blends cost $6.00 per package. She would like to purchase some global combinations and at least 3 boxes of the house blends. Write a system of linear inequalities that describes this situation.

Let x represent the number of international blends and y represent the number of house blends.

The cost of x international blends would be and the cost of y house blends would be.

Since Amy's restaurant has a budget of at most $60 to spend this month on gourmet coffee, so the cost of x international blends and y house blends should be less than or equal to 60.

We can represent this information in an inequality as:

Since Amelia wants to purchase at least 3 packages of the house blends, so y should be greater than or equal to 3. We can represent this information in an inequality as:

Therefore, our required system of inequalities would be 8.50x + 6.00y < 60 and y > 3.

Y = 5x -12 make x subject of formula

Answers

Answer:

(y+12)/5=x

Step-by-step explanation:

y=5x-12

get x by itself

y+12=5x

divide both sides by 5

(y+12)/5=x

okay so Y = 5x - 12
move the -12 to the other side it becomes +
12+ Y = 5x
then minus Y on both sides so the Y cancels Y and 5x- Y is i’m not sure but u guess it cancels so
12=5x then you divide the 5

What are the roots of the equation x 2 + 16 x + 80 = 0 x 2 +16x+80=0 in simplest a + b i a+bi form?

Answers

The quadratic equation x² + 16 · x + 80 has two roots: x₁ = - 1 / 10 + i (4 / 5), x₂ = - 1 / 10 - i (4 / 5).

How to determine the roots of a quadratic equation

In this question we find a quadratic equation of the form a · x² + b · x + c = 0, whose roots can be found by using the quadratic formula:

x = - b / (2 · a) ± [1 / (2 · a)] · √(b² - 4 · a · c)

Where b² - 4 · a · c is the discriminant of the quadratic formula, which offers three cases of solutions:

b² - 4 · a · c > 0: Two different real roots. b² - 4 · a · c = 0: Two equal real roots. b² - 4 · a · c < 0: Two conjugate complex roots.

If we know that a = 1, b = 16 and c = 80, then the roots of the quadratic equation are, respectively:

x = - 16 / 160 ± (1 / 160) · √(16² - 4 · 1 · 80)

x = - 1 / 10 ± (1 / 10) · √(- 64)

x = - 1 / 10 ± i (4 / 5)

The roots are - 1 / 10 + i (4 / 5) and - 1 / 10 - i (4 / 5).

Isabel and Khalil buy peaches and apricots. At the fruit stand, peaches cost $0.85 each, and apricots cost $0.55 each. Tax is included in the cost of each fruit. The friends have $5 to spend. Which is a possible combination of the number of peaches and apricots they can get for $5? Responses 1 peach, 8 apricots 1 peach, 8 apricots 2 peaches, 5 apricots 2 peaches, 5 apricots 3 peaches, 7 apricots 3 peaches, 7 apricots 4 peaches, 3 apricots 4 peaches, 3 apricots

Answers

The possible combination of the number of peaches and apricots they can get for $5 is 2 peaches and 5 apricots.

What is the possible combination?

The equation that represents the total cost of peaches and apricots is:

Total cost = (number of peaches x cost of one peach) + (number of apricots x number of apricots)

$5 = ($0.85 x p) + ($0.55 x a)

Total cost of buying 1 peach and 8 apricots:

($0.85 x 1) + ($0.55 x 8) = $5.25

Total cost of buying 2 peaches and 5 apricots:

($0.85 x 2) + ($0.55 x 5) = $4.45

Total cost of buying 3 peaches and 7 apricots:

($0.85 x 3) + ($0.55 x 7) = $6.40

Total cost of buying 4 peaches and 3 apricots:

($0.85 x 4) + ($0.55 x 3) = $5.05

Answers

Answer:

It will take 37.5 minutes for both containers to reach the same amount of water which is 1050 mL

the normal model n(58, 21) describes the distribution of weights of chicken eggs in grams. suppose that the weight of a randomly selected chicken egg has a z-score of 1.78. what is the weight of this egg in grams? round to the nearest hundredth of a gram.

Answers

The weight of the eggs in grams 95.38 grams.

Let X the random variable that represent the weights of a population, and for this case we know the distribution for X is given by:

X ~ N(58,21)

where µ = 58 and σ = 21

The z score for this case is given by this formula:

z = x -  µ/σ

We know that the value of z = 1.78 and we want to estimate the value of X. If we solve for X from the z formula we got:

X =  µ+1.78σ

= 58 + 1.78×21

= 95.38

So, the corresponding weight for a z score of 1.78 is 95.38 grams.

Hence we get the required answer.

Part B



In doing so, he will save , 2 of 2.
Select Choice
(after tax) over the other store.

Answers

Ramundo will get a better deal at Roller worlds.

This is a question of percentages.

Given that:-

Regular price of rollerblades at roller world = $ 94

Discount at rollerworld = 15 %

Price of rollerblades at Outdoor adventures = $ 81.50

Sales tax = 6 %

Price of rollerblades at roller world after discount = 94 - (15/100)*94 = 94 - 14.1 = $79.9

Price of rollerblades at roller world after sales tax = 79.9 + (6/100)*79.9 = 79.9 + 4.794 = $ 84.694

Price of rollerblades at outdoor adventures = $81.50

Price of rollerblades at roller world after sales tax = 81.50 + (6/100)*81.50 = 81.50 + 4.89 = $ 87.39

$ 84.694 <  $ 87.39

A dolphin was swimming at 20 feet below sea level. Then it dove to 45 feet below its original position. Write an expression that represents the change in depth of the dolphin's dive.

Answers

The expression that represents the change in depth is |-45 + 20|

How to determine the change in depth expression?

From the question, the endpoints are given as

Initial point = 20 feet below the sea level

Final point = 45 feet below the sea level

Rewrite the endpoints properly

This is done as follows

Initial point = -20

Final point = -45

The distance expression between the endpoints is then calculated as

Distance = |Final point - Initial point|

Substitute the known values in the above equation

So, we have the following equation

Distance = |-45 + 20|

Equations are mathematical statements containing two algebraic expressions on both sides of an 'equal to (=)' sign.

Let's find the solution of the equations. The solution of the equation is the value of the variable x. A variable is a number represented by a letter in an equation.

Therefore,

divide both sides of the equation by 4

t = - 32 / 4

add 18 to both sides of the equation

x - 18 + 18 = -72 + 18

add 15 to both sides of the equation

-18 + 15 = x - 15 + 15

Using mathematical operations, we know that temperature after 6 p.m. will be -22.7°F.

What exactly are mathematical operations?Calculating a value using operands and a math operator is referred to as performing a mathematical "operation." The math operator's symbol has predetermined rules that must be applied to the supplied operands or numbers.PEMDAS stands for Parentheses, Exponents, Multiplication, Division, Addition Subtraction (from left to right).

So, the temperature after 6 p.m. will be:

The temperature at different times:

At 9 a.m. = -2.1°FBetween 9 - 12 = +10.8°FBetween 12 - 3 = -13°FBetween 3 - 6 p.m. = -18.4

Now, calculate to get the temperature after 6 p.m. as follows:
