An Air Force plane left Paris and flew toward Moscow. A cargo plane left one hour later flying 40 km/h faster in an effort to catch up to it. After four hours the cargo plane finally caught up. What was the Air Force plane's average speed?
(Use box method)

Answers

Answer 1

Their is your answer hope i get a like

Answer 2

Answer:

The plane is traveling at 160 km/h

Step-by-step explanation:

This is because if the first plane is traveling at 160 and flies for 5 hours it'll travel 800 km. then the second plane will have to catch up in 4 hours since it left an hour late, this means traveling at 160 km with an extra 40 km in 4 hours will get it to the first plane at 800 km in the 4 hours given

what is 6/5 x 25/24 = ?

Answers

The answer is 5/4 or 1 and 1/4 (both answers are correct just different forms), hope this helps !
to find the answer you just multiply straight across so 6 times 25 = 150 and 5 times 24= 120.

then you need to divide 150/120 = 1.25

other forms would be 5/4, 1.25, and 1 1/4. hope this helps!

Answers

Leak rate is affected by the pressure difference (inlet vs outlet), the type of gas that is leaking and the flow characteristics of the leak path. In terms of units, a leak rate can be defined in different ways, but if the SI units are used, then this is expressed in mbar·litre/second.

In a class of 40 students, 75% returned their permission slips for the school field trip. HowIn a class of 40 students, 75% returned their permission slips for the school field trip. How many students returned their permission slips

Answers

Answer:

30 students

Step-by-step explanation:

Given

[tex]Students = 40[/tex]

[tex]\% = 75\%[/tex] ---- percentage of those that returned their slips

Required

Determine the number of those that returned their slips

Represent the number with n

To calculate n, we simply multiply the number of students by the percentage of those that returned their slips

i.e.

[tex]n = 40 * 75\%[/tex]

Convert % to decimal

[tex]n = 40 * 0.75[/tex]

[tex]n = 30[/tex]

Hence, 30 students returned their slips

Answer:

  12. $1,035,057.23

  13. $988,881.23

  14. $7,762.93

  15. $8,686.16

  16. $967,647.66

Step-by-step explanation:

The annuity and amortization formulas are used for problems like this.

  sum of monthly payments = P((1 +r/12)^(12t) -1)/(r/12)

  monthly amount available = P(r/12)/(1 -(1 +r/12)^(-12t))

__

12. The sum of monthly payments of 74, accumulated at 9% compounded monthly for 52 years is ...

  A = ($74)((1 +.09/12)^(12·52) -1)/(.09/12) = $1,035,057.23

__

13. The total of payments is ...

  $74×12×52 = $46,176

So, the interest earned is ...

  $1,035,057.23 -46,176 = $988,881.23

__

14. The amount available in perpetuity is the monthly interest on this account balance.

  $1,035,057.23 × .09/12 = $7,762.93

__

15. The monthly amount available for 25 years is found from the amortization formula:

  A = $1,035,057.23(.09/12)/(1 -(1 +.09/12)^(-12·25)) = $8686.16

__

16. The amortization formula is used for this, too.

  8066 = P(.094/12)/(1 -(1 +.094/12)^(-12·30)) = 0.00833568P

  P = $8066/0.00833568 = $967,647.66

B. Divide both sides by 7
C. Multiply both sides by 7 for the inverse
D. Subtract 1 on both sides for the inverse

Answers

Answer:

C.

Step-by-step explanation:

I'm assuming that the equation is (1+n) / 7 = 3, where 1+n is the numerator and 7 is the denominator.

In this case, to isolate for n, you have to multiply both sides by 7.

then you get 1+n = 3/7, and then you can get n = 3/7 - 1

Suppose the class sizes in high schools in a major public school district are normally distributed with an unknown population mean and standard deviation. If a random sample of 28 high school classes is taken to estimate the mean class size, use a calculator to find the t-score that should be used to find a 90% confidence interval estimate for the population mean.

Answers

Answer:

1.703

Step-by-step explanation:

The reason we try to find t score is because the sample size is below 30, meaning the sample size is small

Hence:

Step 1

We find the degree of freedom

The Degrees of freedom = Number of samples - 1

The random number of samples = 28

= 28 - 1

= 27

Step 2

Using a t score table or t score calculator, we can obtain the t score value for a 90% confidence interval and degree of freedom of 27

90% confidence interval =

10% significance level = 0.10 for two tails or 0.1/2 = 0.05 for one tail

Hence: t90 = 1.703

Alfonso made a scale drawing of a tower. The actaul height of a tower is 25 feet. The scale Alfonso used in his drawing is 1 in.:10 ft. What is the height of the tower in Alfonso's drawing?

Answers

Answer:

2.5 inches

Step-by-step explanation:

Using Alfonso's scale of the drawing, which is 1in=10 ft, we can conclude the height of the tower to be 2.5 inches because

the actual height of the tower is 25 feet

10+10=20, which by following the scale, is 2 inches

we then have 5 left, 5 being half of 10, and .5 being half an inch.

Therefore the height of the tower using Alfonso's scale is 2.5 inches.

For a standard normal distribution, find:______. P(z < -0.34) Express the probability as a decimal rounded to 4 decimal places.

Answers

Answer:

36.69%

Step-by-step explanation:

Given a standard normal distribution :

P(Z < - 0.34) :

Using the Z distribution table :

Look up the value - 0.3 down the row and 0.04 a cross the column. The value at the intersection of the two points gives the required proportion:

P(Z < - 0.34) = 0.3669

0.3669 as a percentage = 0.3669 * 100% = 36.69%

The value can also be obtained using the Z probability calculator.

A local grocery store received a new shipment of apples. The apples arrived in 8 crates with 20 apples in each crate. If the store pays $0.21 per apple and sells each apple for $0.79, what would the profit be after selling all of the apples?
A.
$16.24
B.
$22.12
C.
$92.80
D.
$126.40

Answers

The correct answer is C. $92.80

Explanation:

The first step is to calculate the profit for each apple, this can be found by subtracting the cost the store pays from the selling price.

$0.79 - $0.21 = $0.58

This means for each apple the store sold, the profit (amount of money earned) is $0.58. Now, let's find the total apples the store received, and therefore the total of apples the store can sell.

8 creates each with 20 apples

8 x 20 = 160 apples

Finally, multiply the profit for selling one unit by the total apples

160 x 0.58 = $92.8

If ABC is reflected across the y-axis, what are the coordinates of C?

Answers

Answer:

C

Step-by-step explanation:

The y axis is vertical so you only change the x value.

The coordinate of C after being reflected across the y-axis is (-6, 3) option (C) (-6, 3) is correct.

What is geometric transformation?

It is defined as the change in coordinates and the shape of the geometrical body. It is also referred to as a two-dimensional transformation. In the geometric transformation, changes in the geometry can be possible by rotation, translation, reflection, and glide translation.

We have a triangle shown on the coordinate plane.

If ABC is reflected across the y-axis,

Then the coordinate of C

From the figure, the coordinate of C is(before reflection)

C = (6, 3)

The rule for transformation if reflected across the y-axis:

(x, y) → (-x, y)

(6, 3) → (-6, 3)

Thus, the coordinate of C after being reflected across the y-axis is (-6, 3) option (C) (-6, 3) is correct.

Find the total amount given the original price, tax rate and tip rate. Round to the nearest hundredth if necessary.

Original price: $101.33

Tax rate: 6.7%

Tip: 18%

Answers

Answer:

The total cost would be $126.36

Step-by-step explanation:

18% plus 6.7% is 24.7%. 24.7% of 101.33 is 25.028. Add $101.33 and $25.03

The total amount including tax rate and tip rate is $127.58.

What is the percentage?

A percentage is a value per hundredth. Percentages can be converted into decimals and fractions by dividing the percentage value by a hundred.

Given, The original price is $101.33.

Now, Tax rate is 6.7%.

Price with tax is,

= (106.7/100)×101.33.

= $108.12.

The price with tip is,

= (118/100)×108.12.

= $127.58.

So, The total price is $127.58.
