Determine the better buy by comparing unit rates.
1. 20 pens for $1.60 or 25 pens for $2.25
2. 13 berries for $2.60 or 17 berries for $3.06

Answers

To find the better buy we have to find the cost per pen for each.

1. 20 pens for $1.60 -> 1.60/20 = .08 cents per pen.
25 pens for $2.25 -> 2.25/25 = .09 cents per pen.

The best buy is 20 pens for $1.60 because it's cheaper per pen. 

2. 13 berries for $2.60 -> 2.60/13 = .20 cents per berry
17 berries for $3.06 -> 3.06/17 = .18 cents per berry

The best buy is 17 berries for $3.06 because it's cheaper per berry.
1. 20 pens for $1.60
2. 17 berries for $3.06


Round 0.955 inches to the nearest tenth of an inch

Answers

The correct answer is:  
_____________________________________________________
        "1.0 inch" ;  (or, write as: "1.0 in." ; or even: "1.0 inches" .) .
____________________________________________________
Given:  "0.995 inches" ; round to the nearest TENTH of an inch.
 
(which means; round to the nearest "first decimal point" ; and to include the actual first decimal point (and that decimal point only, the "tenths place").
 
We are given the number:  "0.955" .  This is given to the nearest THOUSANDS.  

We examine the "tenths place":  "0.9" .  So we know our choices are:

"0.9" (round down to the nearest tenths place); or, "1.0" (round up to the nearest tenths place).  

            →  We examine the number: "0.955" ; and look to the next value, the "hundredths place".  
            → If that digit is 5 or greater (i.e. 5 to 9), we "round up" ; and the correct answer is:  "1.0" .  If that number is "4" or less (i.e. 0 to 4), we round down; and the correct answer is:  "0.9".
________________________________________
In the case of our give value:  "0.955" .  The digit to the right of "9" is "5" ; so, as previously mentioned, we "round up" ;  to:  "1.0".

Do not forget to include the units.
______________________________________________________
The answer is:  1.0 inches.
______________________________________________________

The nearest tenth is the first digit after the decimal point. The round 0.955 inches to the nearest tenth of an inch is 1.0 inches.

Given 0.995 inches

round to the nearest tenth of an inch.

This means round to the nearest first decimal point and to include the actual first decimal point (and that decimal point only, the tenth place).

We are given the number 0.955.  This is given to the nearest thousands.  

We examine the tenth place at 0.9.

So we know our choices are

What is the nearest tenth?

The nearest tenth is the first digit after the decimal point.

0.9 (round down to the nearest tenths place) or 1.0 (round up to the nearest tenths place).  

We examine the number 0.955 and look to the next value, the hundredths place  

If that digit is 5 or greater we round up and the correct answer is  1.0.

If that number is 4 or less (i.e. 0 to 4), we round down and the correct answer is 0.9.

In the case of our give value:  0.955.  

The digit to the right of 9 is 5 so, as previously mentioned,

we round up to 1.0.

Therefore, The round 0.955 inches to the nearest tenth of an inch is 1.0 inches.

The answer is  1.0 inches.

Answers

Part (a)

Dependent variable = height

"depends on age" indicates that age is independent.

Part (b)

Independent variable = amount of sleep
Dependent variable = mood

-----------------------------------
Part (c)

Independent variable = time water has been running
dependent variable = amount of water in the tub

Time is usually the independent variable
-----------------------------------
Part (d)

Independent variable = speed
dependent variable = distance from home

Melanie prepared 7 1/2 tablespoons of her spice mixture she is 1/4 tablespoon to make a batch of barbecue sauce estimate the number of batches of barbecue sauce she can make by using the spice mixture

Answers

She can make 30 batches

Answer: There are 30 batches of barbeque sauce that she can make by using the spice mixture.

Step-by-step explanation:

Since we have given that

Number of tablespoons of her spice mixture = [tex]7\dfrac{1}{2}=\dfrac{15}{2}[/tex]

Number of tablespoons to make a batch of barbeque sauce = [tex]\dfrac{1}{4}[/tex]

so, the number of batches of barbeque sauce would be

[tex]\dfrac{15}{2}\div \dfrac{1}{4}\\\\=\dfrac{15}{2}\times 4\\\\=15\times 2\\\\=30[/tex]

Hence, there are 30 batches of barbeque sauce that she can make by using the spice mixture.

Find the percent of the total area under the standard normal curve between the given z-scores. z= -1.10 and z= -0.36

Answers

0987[tex] \sqrt{x} \left[\begin{array}{ccc}1&2&3\\4&5&6\\7&8&9\end{array}\right] \left[\begin{array}{ccc}1&2&3\\4&5&6\\7&8&9\end{array}\right] [/tex]

To find the percent between two z-scores under the standard normal curve, subtract the individual areas. In this case, the percentage between z = -1.10 and z = -0.36 is 1.72%.

To find the percent of the total area under the standard normal curve between z-scores, you need to first calculate the difference between the two areas to the left of each z-score. Given that the area to the left of z = -1.10 is 0.3446 and the area to the left of z = -0.36 is 0.3618, you can find the percent between them by subtracting these values: 0.3618 - 0.3446 = 0.0172 or 1.72%.

Evaluate the expression 14x + y when x = 11 and y = 20.

Answers

Evaluating an expression just means to replace x by its value and y by its value and do some calculus.
By hypothesis, x = 11 and y = 20.

So in the expression 14x + y, you just replace x by 11 and y by 20.
14x + y = 14 * 11 + 20 = 154 + 20 = 174

-3(y-5)=24 What is y ?

Answers

Distribute into the parenthesis and you get: -3y+15=24. Now, subtract 15 on both sides and you will get: -3y = 9. Finally, divide -3 on both sides and you will get the final answer: y = -3. You can check your answer by substituting -3 into the original equation: -3(-3-5) = 24. 9 + 15 = 24. 24 = 24
 -3(y - 5) = 24             Use the Distributive Property.
 -3y + 15 = 24            Subtract 15 from both sides of equation.
 -3y = 9                       Divide -3 from both sides of the equation.
 y = -3                         This is your final answer.

Sam wants to know how long it will take to fill his baby pool that holds 24 gallons. After 1 minute, there are 2 gallons of water in the pool. He plots the points (0,0) and (1,2) on his coordinate plane. What is the x-value of the point (x, 24)?

Answers

i believe the x value is 12. so it is 12, 24

Answer:

(12,24)

Step-by-step explanation:

Givens

The pool holds 24 gallons.The rate is 2 gallons of water per minute.The line that represents the problem passes through points (0,0) and (1,2).

We can deduct the equation that represents this problem using the point-slope formula

[tex]y-y_{1} =m(x-x_{1} )\\y-2=2(x-1)\\y=2x-2+2\\y=2x[/tex]

So, for [tex]y=24[/tex], we have

[tex]y=2x\\24=2x\\x=\frac{24}{2}\\ x=12[/tex]

Therefore, after 12 minutes there were 24 gallons of water in the pool. The right answer is (12,24).

At 2:30 am the temperature in Joelle is 3 F. The temperature drops 3/4 of a degree in 30 min. What is the temperature on Joelle at 3:00am?

Answers

The answer is B. 2.25 degrees Fahrenheit because if you subtract 3/4 from 3, you shall get 2.25.

Answer:  B. [tex]=2.25^{\circ}F[/tex]


Step-by-step explanation:

Given: At 2:30 am the temperature in Joelle is 3 F.

The temperature drops 3/4 of a degree in 30 min.

3/4 of a degree= [tex]\frac{3}{4}\times1^{\circ}F=\frac{3}{4}=0.75^{\circ}F[/tex]

Therefore, the temperature on Joelle after 30 min= [tex]3^{\circ}F-\frac{3}{4}\ of\ 1^{\circ}F[/tex]

[tex]=3^{\circ}F-0.75^{\circ}F[/tex]

[tex]=2.25^{\circ}F[/tex]

Thus, the temperature on Joelle at 3:00am=[tex]=2.25^{\circ}F[/tex]

OF bisects EOF. EOF=y+30 and FOG=3y-50. solve for y.

Answers


It always helps to draw a picture. Given the information, Segment OF is the center line that is bisecting this angle.

Since it's bisecting (cutting in half)... we can simply set the two angles equal to each other.

y+30=3y-50
-2y+30=-50
-2y=-80
y = 40

C)40.
Final answer:

Setting the given equations equal to each other, we can solve for y and determine that y equals 40.

Explanation:

The question states that OF bisects EOF, which means that EOF and FOG are equal. Hence, you can set the two equations equal to each other to solve for y.

EOF = y + 30FOG = 3y - 50

Set EOF equal to FOG:

y + 30 = 3y - 50

To solve for y, first simplify the equation by subtracting y from both sides:

30 = 2y - 50

Then add 50 to both sides to isolate the y variable on one side:

80 = 2y

Finally, divide both sides by 2 to solve for y:

y = 40
