Answer:

* 55.5 miles

Step-by-step explanation:

17² + b² = 23²

289 + b² = 529

b² = 240

b = 15.491 ≈ 15.5

17 + 23 + 15.5 = 55.5

You can also simply notice B is the only answer with a .5 decimal and thus don't have to add.

Answer:

45 and 50

Step-by-step explanation:

each large square is 5 minutes.

for 0 < t < 30, there are three columns of 15 minutes ( 3 x 5)

15 x 3 = 45

for 40 < t < 60 there is two columns of 25 minutes (5 x 5)

25 x 2 = 50

From the given histogram we have the values of the empty box are 45 and 50.

We have given that,

the incomplete histogram and table give some information about the waiting time in minutes, experienced by patients at a dental surgery.

We have to complete the given table.

A histogram is an approximate representation of the distribution of numerical data. The term was first introduced by Karl Pearson.

each large square is 5 minutes.

for 0 < t < 30, there are three columns of 15 minutes ( 3 x 5)

15 x 3 = 45

for 40 < t < 60 there is two columns of 25 minutes (5 x 5)

25 x 2 = 50

Therefore the values of the empty box are 45 and 50.

Answer:

66

Step-by-step explanation:

subtract each external angle by 180 to find the interior angle.

Since you know that all of the interior angles add up to 540 because 180(n-2)

with n is how many sides in the polygon

so 180(5-2)=540

now take each value and subtract it by 180

180-(45)=135

180-(40)=140

180-(x)=180-x

180-(77)=103

180-(2x)=180-2x

135+140+180-x+103+180-2x=540

738-3x=540

x=66

Answer:

D) 12 feet

Step-by-step explanation:

The formula for area of a rectangle is length x width. We have this information: length x 7 = 84. To solve for this, divide 7 from both sides to get: length = 12 feet.

Hope it helps!

Answer:

Answer:

Theoretical probability is a calculated value whereas experimental is an observed value. Theoretical is more reliable because it is usually not subject to all the testing failures that are possible. Experimental probability is only used in practice or when there isn't any theory.

Both are useful, but theoretical probability is more reliable because it has been studied and matured, so it is more foolproof than experiments.

Answer:

12 minutes

Step-by-step explanation:

First substitute 141°F for T in the given equation.

Then isolate the exponential term.

Now rewrite the equation as a natural log, and solve for x.

After 12 minutes will the temperature of the coffee be approximately 141°F.

Temperature is the degree of hotness or coldness expressed in terms of any of numerous scales, such as Fahrenheit and Celsius. Temperature suggests the route wherein heat strength will spontaneously flow—i.e., from a warmer body (one at a better temperature) to a less warm frame (one at a lower temperature).

diploma measures of temperature are typically expressed with the ° temperature scale: The sample became heated to 80 °C.

Substitute the 141°F in the equation

     ⇒T = 75 + 120e-0.051

     ⇒ 141 = 75 + 120x - 0.051

     ⇒ 120x = 141 -75 + 0.051

     ⇒120x = 66.051

Step-by-step explanation:

Answer:

$16.20

Step-by-step explanation:

24.00 × 25%= 6.00

24.00 - 6.00 = 18.00

18.00 × 10%=1.80

18.00 - 1.80 = 16.20

A percentage is a way to describe a part of a whole. The final cost of the book will be $16.2.

A percentage is a way to describe a part of a whole. such as the fraction ¼ can be described as 0.25 which is equal to 25%.

To convert a fraction to a percentage, convert the fraction to decimal form and then multiply by 100 with the '%' symbol.

Given the cost of the book is $24. Therefore, the cost of the book after a 25% discount is,

Cost of book after discount = $24×(100%-25%) = $18

Now, the cost after the 10% counpon will be,

Cost after the 10% counpon = $18×(100%-10%) = $16.2

Hence, the final cost of the book will be $16.2.
