pls help!!
The side of a regular pentagonal pyramid is 6 feet long. The slant
height of the is 7 feet long. What is the lateral area of the pyramid.

Answer:

(1/3) Pi r^2 h

Step-by-step explanation:

The volume of a cone (or pyramid, for that matter) is 1/3 the area of the base times the height.

Cones have bases that are circles, so their areas are Pi r^2, usually written [tex]\pi r^2[/tex], Pi times the radius squared.

[tex]V=\frac{1}{3}\pi r^2h[/tex]

Answer:

Correct answer A

Step-by-step explanation:

40% model cars  of 45 models  is 18 model cars (the rest is model airplanes)

45-18 =27

27 model airplanes

Answer:

D.)

No. There are only 12 bolts that have lengths greater than 1 inch, which is not enough.

Step-by-step explanation:

Based on information provided by the dot plot above, we can deduce that the number of bta longer Than 1 inch are those with length ; 1 1/8, 1 3/8, 1 4/8

Counting the number of these bolts :

1 1/8 = 5 bolts

1 3/8 = 3 bolts

1 4/8 = 4 bolts

Hence, total number of bolts longer Than 1 inch :

(5 + 3 + 4). = 12 bolts

The number of bolts longer than 1 inch is 16. Therefore, he does not have enough bolt for the project.

Answer:

50+20x=290 or 50+(20x12)=290

Step-by-step explanation:

Answer:

50 + 20m = 290

Step-by-step explanation:

The answer is 50 + 20m = 290, because Jim paid a membership fee that was $50. Then each month he paid $20 because of his new membership. Jim never paid $50 a month, that was only his starter fee, but then gradually paid $20 every month so it would be 20m. Hope this helped.

Answer:

11x + 5

Step-by-step explanation:

To simply, just combine like terms.

10 + 7x - 5 + 4x

[Add 7x and 4x]

↓

11x + 10 - 5

[Subtract 5 from 10]

↓

11x + 5

Answer [tex]m=250w[/tex]

Step-by-step explanation:

To write an engebraic expression, you should first start off by defining the variables.

Money earned = m

Weeks = w

Next, you have to define the relationship.

Shawn earns $250 per week, so in 2 weeks, he will earn 500, 3 weeks, 750, and so on. I did this by mulitplying, so amount of weeks times the amount of money earned would equal the total money he earned over "w" amount of weeks.

To create the expression, you just have to put the numbers and variables together.

m (money earned over "w" weeks) = 250 (money per week) w (number of weeks).

m=250w

Answer:

ok

Step-by-step explanation:

Answer:

w = 7 feet

Step-by-step explanation:

Volume of a rectangle prism = length × width × height

Length = 7 feet

Width = ?

Height = 3 1/4 feet

Volume = 159 1/4 cubic feet

Volume of a rectangle prism = length × width × height

159 1/4 = 7 × w × 3 1/4

637/4 = 7 × w × 13/4

637/4 = 7 × 13/4 × w

637/4 = 91/4w

w = 637/4 ÷ 91/4

= 637/4 × 4/91

= 637*4 / 4*91

= 2548 / 364

w = 7 feet

Answer:

y = 54

Step-by-step explanation:

45 = y - 9

 +9     +9

54 = y

y= 54            

Answer:

Think of the equation as an equation for a line  y = m x + b  where in this case  C = 5 9 ( F − 32 )  or  C = 5 9 F − 5 9 ( 32 )  You can see the slope of the graph is  5 9 , which means that for an increase of 1 degree Fahrenheit, the increase is  5 9  of 1 degree Celsius.  C = 5 9 ( F )  C = 5 9 ( 1 ) = 5 9  Therefore, statement I is true. This is the equivalent to saying that an increase of 1 degree Celsius is equal to an increase of  9 5  degrees Fahrenheit.  C = 5 9 ( F )  1 = 5 9 ( F )  ( F ) = 9 5  Since  9 5  = 1.8, statement II is true.  The only answer that has both statement I and statement II as true is D, but if you have time and want to be absolutely thorough, you can also check to see if statement III (an increase of  5 9  degree Fahrenheit is equal to a temperature increase of 1 degree Celsius) is true:  C = 5 9 ( F )  C = 5 9 ( 5 9 )  C = 25 81 ( which is ≠ 1 )  An increase of  5 9  degree Fahrenheit leads to an increase of  25 81 , not 1 degree, Celsius, and so Statement III is not true.  The final answer is D.

Answer:

Radian angle = 1.154

Central angle = 66.123°

Step-by-step explanation:

Area of Sector, A

A = 1/2 * r² * θ ; θ measured in radian

A = 9 π

r = 7

9 π = 1/2 * 7² * θ

9 π = 24.5θ

θ = 9 π / 24.5

θ = 1.154 radian

1 radian = 57.296°

1.154 radian = (57.296 * 1.154)

1.154 radian = 66.123°
