An ice cream shop is choosing a milk delivery service. The Spotted Cow charges $2.80 per gallon, plus a $2 delivery fee. Dairy Farms charges $2.10 per gallon, plus a $10 delivery fee. If the ice cream shop uses 20 gallons a milk per week, which service is a better deal? Group of answer choices

Answer:

C

Step-by-step explanation:

The actual average time = 81.5 minutes

The correct answer is an option (B) 81.48 minutes

"percent error = [(estimated value - actual value) / (actual value)] × 100"

For given example,

percent error (e) = 3%

estimated average time spent (x) = 84 minutes

We need to find the actual average time spent (y)

Using the formula of percent error,

⇒ e = [(x - y)/y] × 100

⇒ 3 = (84 - y)/y  × 100

⇒ (84 - y)/y = 3/100

⇒ (84 - y) / y = 0.03

⇒ 84 - y = 0.03y

⇒ 84 = 0.03y + y

⇒ 84 = (1.03)y

⇒ y = 81.5 minutes

Therefore, the actual average time = 81.5 minutes

The correct answer is an option (B) 81.48 minutes

Answer:

Fourth option

Step-by-step explanation:

The answer is the fourth option "difference of squares method." It's not the first option because the substitution method is when you pick one of the equation in a system of equations, solve it for a variable and then plug the variable into the other equation to help solve. It's not the second option because the graphing method is used to solve a system of equations by graphing the equations on the same coordinate plane, it's not the third option because the addition method is also known as the elimination method which is the third method to solving a system of equations. Therefore your answer is the fourth option.

Answer: B. 5 ∙ y + 5 ∙ 2 + 4

Step-by-step explanation:

The options are:

a. 5 + y + 5 + 2 + 4

b. 5 ∙ y + 5 ∙ 2 + 4

c. 5 ∙ y + 5 ∙ 4 + 4

d. 5 ∙ y + 5 + 2 + 4

To solve the question, we have to expand 5(y+2)+4. This will be:

= (5 × y) + (5 × 2) + 4

= 5 ∙ y + 5 ∙ 2 + 4

= 5y + 10 + 4

= 5y + 14

So you have it right. 15 5/7 in

Step-by-step explanation:

C = πd

All you can do now is substitute what has been given

Diameter = 5

Pi = [tex]\frac{22}{7}[/tex]

C = [tex]\frac{22}{7}[/tex] * 5

Multiply from across

22 * 5 = 110 ( numerator)

7 * 1 = 7 (denominator)

110/7 (improper fraction) = 15.71428571428571 ( as a decimal) = 15 5/7 ( as a mixed number)

Ik its 15 5/7 because 1. the 15 wont change, and 2 5/7 = 0.7142857142857143, which is the same one as above

Answer:

cos ([tex]\frac{7\pi}{8}[/tex]) = [tex]-\frac{\sqrt{2+\sqrt{2}}}{2}[/tex]

Decimal value: −0.9238795325...

Step-by-step explanation:

Write,

cos [tex]\frac{7\pi}{8}[/tex] = cos [tex](\pi-\frac{\pi}{8})[/tex] = −cos [tex]\frac{\pi }{8}[/tex]

Now using half angle formula, cos(x) = 2 cos²([tex]\frac{\pi }{2}[/tex]) − 1, we can write cos [tex]\frac{\pi }{4}[/tex] = 2

cos²([tex]\frac{\pi }{8}[/tex]) − 1

This means [tex]\frac{1}{\sqrt{2}}[/tex] + 1 = 2 cos²([tex]\frac{\pi }{8}[/tex])

2 cos²([tex]\frac{\pi }{8}[/tex]) = [tex]\frac{\sqrt{2}+1}{\sqrt{2}}[/tex]

cos²([tex]\frac{\pi }{8}[/tex]) = [tex]\frac{\sqrt{2}+1}{2\sqrt{2}}[/tex]

cos([tex]\frac{\pi }{8}[/tex]) = [tex]\sqrt{\frac{\sqrt{2}+1}{2\sqrt{2}}}[/tex]

Simplify,

[tex]\sqrt{\frac{\sqrt{2}+1}{2\sqrt{2}}}[/tex] = [tex]\sqrt{\frac{2+\sqrt{2}}{4}[/tex] = [tex]\frac{\sqrt{2+\sqrt{2}}}{2}[/tex]

Hence,

cos ([tex]\frac{7\pi}{8}[/tex]) = −cos ([tex]\frac{\pi }{8}[/tex]) = [tex]-\frac{\sqrt{2+\sqrt{2}}}{2}[/tex]

The exact value of cos(7pi/8) is [tex]\rm -\dfrac{\sqrt{2+\sqrt{2}} }{2 }[/tex] and this can be determined by using the trigonometric properties.

Given :

Expression  -- [tex]\rm cos(\dfrac{7\pi}{8})[/tex]

The following steps can be used to determine the exact value of the given expression:

Step 1 - Write the given expression.

[tex]=\rm cos(\dfrac{7\pi}{8})[/tex]

Step 2 - Rewrite the above expression.

[tex]= \rm cos(\dfrac{8\pi - \pi}{8})[/tex]

Step 3 - The above expression is reduced to:

[tex]= \rm -cos(\dfrac{ \pi}{8})[/tex]    --- (1)

Step 4 - According to the trigonometric properties:

[tex]\rm cos(x) = 2 cos^2(\frac{x}{2})-1[/tex]

Step 5 - Substitute the value of x = [tex]\pi[/tex]/4 in the above expression.

[tex]\rm cos(\frac{\pi}{4}) = 2 cos^2(\frac{\pi}{8})-1[/tex]

Step 6 - Simplify the above expression.

[tex]\rm cos(\frac{\pi}{8})=\sqrt{\dfrac{\dfrac{1}{\sqrt{2}} +1}{2}}[/tex]

[tex]\rm cos(\frac{\pi}{8})=\sqrt{\dfrac{1+\sqrt{2} }{2\sqrt{2} }[/tex]

[tex]\rm cos(\frac{\pi}{8})=\dfrac{\sqrt{2+\sqrt{2}} }{2 }[/tex]

Step 7 - Substitute the value of cos([tex]\pi[/tex]/8) in the expression (1).

[tex]\rm -cos(\frac{\pi}{8})=-\dfrac{\sqrt{2+\sqrt{2}} }{2 }[/tex]

A ratio shows us the number of times a number contains another number.

Given that a recipe calls for 3 cups of pecans for every 5 cups of walnuts. Therefore, the ratio of pecans to walnuts is,

Pecans/ Walnuts = 3 cups / 5 cups

Now, the number of cups of pecans that should be added to 8 cups of walnuts is,

Pecans/ Walnuts = 3 cups / 5 cups

Pecans/ 8 cups = 3 cups / 5 cups

Pecans = (8×3)/5 cups

Pecans = 4.8 cups

Hence, the correct option is C.

The answer is 1/2.

Step-by-step explanation:

1 1/3-5/6=

1 1/3 needs to be turned into a improper fraction. 1 1/3=4/3.

Now we can do 4/3-5/6 but, the denominator has to be the same. We can make them 8/6-5/6.

*(Whatever happens to the denominator, has to happen to the numerator.)

8/6-5/6=3/6. Typically, the answer could be 3/6 but you could also simplify it to 1/2.

So, the answer would be 1/2.

to find c we use 15 and 8 into the formula of "a^2 + b^2 = c^2" which is 17. Now we use 17 and 10 as a and b to find c in the formula which is d.

a^2 + b^2 = c^2

10^2 + 17^2 = x^2

100 + 289 = x^2

389 = x^2
