Answer:

144 Inches cubed

Step-by-step explanation:

8 × 6 × 6 = 288.

288 / 2 = 144.

you multiply to get the original volume then divide by 2 because the tank is only half full.

Answer:

1.50x + 2.25y ≤ 30

Step-by-step explanation:

Hi, let’s say that 'y' represent the tablecloths.

So, we have to write an inequality:

The product of the number of balloons (x) and the cost of each one (1.50) plus the product of the number of tablecloths (y) and the cost of each tablecloth (2.25) must be less or equal to Rosie's budget (30)

Mathematically speaking:

1.50x + 2.25y ≤ 30

Feel free to ask for more if needed or if you did not understand something  

Answer: The inequality can be written as 1.5x + 2.25y ≤ 30

Step-by-step explanation: What Rosie needs is an expression that shows  the highest she can spend on tablecloths and balloons. If the question states that she cannot spend more than 30 dollars, then it simply means she can either spend a maximum of 30 dollars, OR any amount below 30 dollars. So what she needs is an inequality that shows her spending as being less than or equal to 30.

Let the balloons be represented by letter x and the tablecloths be represented by the letter y. If each balloons cost 1.50 dollars, then the total cost of balloons equals 1.5 times x or simply 1.5x. Likewise, if each tablecloth cost 2.25, then the total cost of tablecloths shall be 2.25y.

The possible number of balloons and tablecloths that she can buy based on the conditions given can be expressed as follows;

1.5x + 2.25y ≤ 30

Answer:

84 dollars

Step-by-step explanation:

use x to represent the amount of money Laura had when she started shopping.

use y to represent the amount of money she had left after buying a pair of shorts.

You can create these two equations:

3/4x=y

2/3x=42

now, subsitute the value of y into the second equation.

2/3(3/4x)=42

1/2x=42

x=84

Answer: C. There is evidence that teachers at Woodlands Middle may prefer the aquarium more than students.

Step-by-step explanation:

The results of the poll showed that 50% of teachers preferred to go to the aquarium whilst only 20% of students prefer to go to the aquarium.

With 5 in every 10 teachers preferring to go to the aquarium and only 2 in every 10 students preferring the aquarium that is clear evidence that there are is a higher proportion of teachers wanting the aquarium than the students. This shows therefore that relatively speaking, teachers prefer the Aquarium more than students do.

The Answer is C. There is evidence that teachers at Woodlands Middle may prefer the aquarium more than students.

Answer:

169.6

Step-by-step explanation:

We can use trig to find the missing side (sin specifically).  sin(x)=opposite/hypotenuse.  where x is the angle.  VWX is 20 degrees.  The side opposite to that angle is VX or 58.  We dont know the hypotenuse.  If we were to substitute values into sin(x)=opposite/hypotenuse, we would get sin(20)=58/hypotenuse.  sin(20) in the calculator is 0.342020143...  so we can rewrite the equation as 0.342020143=58/hypotenuse.  Lets call the hypotenuse h.  If we multiply h on both sides, we can try to find what h is equal to.  0.342020143h=58.  Now we can divide 0.342020143 on both sides to isolate h.  h=169.58... or if we round it, we get 169.6

In a report it is said that the predicted minimum temperature is -24 ° C and the maximum is -20 ° C. If the minimum temperature represents colder than the maximum temperature, should it not appear on the reverse? Explain your answer.

Solution

No, it shouldn't appear on the reverse. This is because, just as negative numbers work, they decrease, the further we move away from 0.

Celsius temperature scales are calibrated with respect to the freezing point of water. The freezing point of water serves as the reference point and is called the 0°C.

Temperatures higher than the freezing point of water taken on positive values and temperatures lower, take on negative values. The lower the temperature, the bigger the absolute value of the negative value is.

For example, just like In the question provided, -24°C represents a temperature that is 24° lower than the freezing point of water while -20°C represents a temperature that is 20° lower than the freezing point of water. It is evident that -24°C really is a lower temperature than -20°C.

Answer:

40 students per bus

Step-by-step explanation:

147 (Og #)-27(Number riding cars, irrelevant)=120

120/3 (# of buses)= 40 students per bus

Answer:

40 students

Step-by-step explanation:

First, let’s find how many students rode the buses.

There was a total of 147 students on the trip, and 27 rode in cars. The rest rode in buses.

The difference between 147 and 27 will be how many took buses.

Subtract 27 from 147

147-27=120

120 students rode the buses. There were 3 buses, and the students were evenly divided between each bus. Divide 120 by 3.

120/3=40

Therefore, 40 students were on each bus.

Answer:

1. blue

2. blue because I measured both lines with a ruler.

3. this one was harder to decide because when I look at the picture both lines look the same length but since I measured both lines with a ruler I realized that the blue line was longer that the red line.

Step-by-step explanation:

I actually measured both lines with a ruler and the blue line is just barely bigger that the red line

Answer:

Down payment is $258

Installment price is $1766.22

monthly payment is $83.79

Step-by-step explanation:

Down payment is 15% of $1,720 which is $258  (15%*$1720)

Monthly payment can be computed using pmt formula in excel

=pmt(rate,nper,-pv,fv)

rate is the interest rate per month which 4%/12=0.33%

nper is the number of months of payments that is 18

pv is the finance amount which is the price minus down payment i.e $1462 *($1720-$258)

fv is the total finance amount plus interest which is unknown i.e 0

=pmt(0.33%,18,-1462,0)=$ 83.79  

installment price =down payment +total repayment

                             =$258+($83.79*18)=$1766.22

1 centimetre is = 0.01 meter

therefore the scale in Brennan drawing is 1 centimetre  is used to represent 7 metres

Answer:

1 cm:7 meters

Step-by-step explanation:

The scale drawing shows the length in the drawing, then a colon and the actual lenght of the object. The actual building is 147 meters long and the drawing is 21 centimeters long. From this, we have:

21 cm:147 meters

As both numbers can be divided by 21, you can simplify and you would have that the scale of the drawing is:

1 cm:7 meters

Answer:

The median is NOT the same thing as a quartile.

The median is a measure of center.

Answer:

1. 18 girls

2. 5 girls will be added to maintain the same ratio of boys and girls

Step-by-step explanation:

1. Boys : Girls = 14 : 12

14 + 12 = 26, 39/26 = 1.5

Boys: 14 x 1.5 = 21

Girls: 12 x 1.5 = 18

21 + 18 = 39 athletes, there are 18 girls on the 39 athletes.

2. Boys : Girls = 14 : 12

14 : 12

7   : ?

14 - 7 = 12 - ?

7 = 12 - ?

12 - 7

Step-by-step explanation:

You received 1/4 pound of candy from your grandmother.

You received 1/2 pound of candy from your sister.

You received 1/8 pound of candy from your best friend.

The total amount of candy you received is given as the sum of all the candy that he received from your grandmother sister and best friend.

The total amount of candy is therefore:

¼ + ½ + ⅛ = ⅞ pound

You received ⅞ pound of candy in total.

Answer:

False

Step-by-step explanation:

3/4 = 9/16

Multiply the left side by 4/4 to get a common denominator

3/4*4/4 = 12/16

This is not equal to 9/16 so this is not a proportional relationship

Answer:

False

Step-by-step explanation:

3 times 3 is 9, so if this is a proportional relationship between the two fractions than 4 times 3 will be 12.

Since it is a 16 rather than a 12 you know that this cannot be right. Whatever you do to the top you have to do to the bottom, and in this case. That's just not happening.

The acceleration is 4.4 km/sec/sec

Step-by-step explanation:

Acceleration of motorcycle is 4.44 km/sec²

Starting velocity = 10 km/hr

Final velocity = 50 km/hr

Time taken = 9 second

Acceleration of motorcycle

Acceleration of motorcycle = [Final velocity - Initial velocity] / Time taken

Acceleration of motorcycle = [50 - 10] / 9

Acceleration of motorcycle = [40] / 9

Acceleration of motorcycle = 4.44 km/sec²
