what is the measure of each angle in a pentagon if the lengths of all five sides are equal? A-180 B-120 C-108 D-60

Answer:

410 students attend Ridgewood Junior High.

Step-by-step explanation:

To solve your equation, you have to divide 41 by 10%. This will give you your answer of 410, or the total. Have a good day!

Answer:

26 cm

Step-by-step explanation:

c = a^2 + b^2 = 10^2 + 24^2 = 26

Answer:

26m.

Step-by-step explanation:

since the triangle has a 90° angle, it means that the triangle is a Right - angled triangle. So, we are going to use the pathagorean theorem to find the missing side.

a² + b² = c²

a and b are the two shorter and adjacent sides to the 90° angle

c is the hypotenuse

10² + 24² = c²

100 + 576 = c²

676 = c²

find the square root of 676 to get c = 26.

Step-by-step explanation:

Answer:

A proportional relationship between two quantities is one in which the two quantities vary directly with one and other. If one item is doubled, the other, related item is also doubled. Because of this, it is also called a direct variation. The equations of such relationships are always in the form y = mx , and when graphed produce a line that passes through the origin. In this equation, m is the slope of the line, and it is also called the unit rate, the rate of change, or the constant of proportionality of the function.

Answer:

The base of a right pyramid is an equilateral triangle with area 16√3 cm².  area of one of its lateral faces is 30 cm²

To find :   height (in cm) i

Solution:

The base of a right pyramid is an equilateral triangle with area 16√3 cm²

Area of an equilateral triangle = (√3 / 4) Side ²

(√3 / 4) Side ²  = 16√3

=> Side ²  = 64

=> Side = 8 cm

Distance of center of triangle to mid point of Side for Equilateral triangle = side/ 2√3     = 8/ 2√3  = 4/√3

Let say Height  = H

Slant Height =  √((4/√3)² + H²)

Area of lateral surface = (1/2) * base * Slat Height

= (1/2) * 8 * Slant height = 30

=> Slant height = 15/2

15/2   = √((4/√3)² + H²)

=> 225/4  =  16/3  + H²

=> 611/12  = H²

=> H = 7.135  cm

Answer:

A

Step-by-step explanation:

The exponent 4 means it is 2/3 multiplied by itself 4 times.

So it would be 2/3*2/3*2/3*2/3

Answer:

Step-by-step explanation:

sale price = original price minus discount.

discount = original price * discount percent / 100.

let s represent the sale price.

let p represent the original price.

let d represent the discount.

let k represent the discount percent.

the above formulas become:

s = p - d

d = p * k/100

we know that s = 315.

we know that k = 30.

formulas become:

315 = p - d

d = p * 30/100

simplify these formulas to get:

315 = p - d

d = .3p

Answer:

24 cm^2

Step-by-step explanation:

The base is 4cm by 6cm, so the base area is 24cm^2

The height (h) would be equal to V/A =[tex]\frac{240}{24}[/tex] = 10cm

Answer

the answer is 10 but i dont see the answer so  i think it's 40cm

The greatest, farthest depths listed are the Guided Missile and Scientific submarines' depths, 850 and 925 feet. So, The answer is D, Guided Missile and Scientific.

Good luck ^^ Hope this helps :)

Answer: B

because of the reason given. (smaller numbers are father left and larger numbers are father right on the number line).

Answer: A is the answer

Step-by-step explanation: since -9 is a negative is and 9 is positive, -9 will appear furthest to the left on a number line.

Answer:

Option 'B' is correct.

Step-by-step explanation:

Since we have given that

Number of lemons used is denoted by 'y'.

Number of glasses of lemonade is denoted by 'x'.

As we can observe that ,

[tex]\frac{6}{24} = \frac{8}{32} = \frac{7}{28} = \frac{2}{8} = \frac{4}{16} = \frac{1}{4} \\[/tex]

so we can write i as

[tex]\frac{x}{y} = \frac{1}{4}[/tex]

By cross multiplication

y=4x

So, if write it in the form y=kx,

It will be y=4x.

Answer:

45°

Step-by-step explanation:

All angles in a triangle add up to 180°

180 - (90 + 45)

= 180 - 135

= 45

Therefore the missing angle is 45°

Answer:  answer is 45

Step-by-step explanation:

I added 90 with 45, got 135, then subtracted 180 with 135...

Answer:

Step-by-step explanation:

21: 9/15+1/4= 0.85, if you turn that into a percent it is 85%

Step-by-step explanation:

35/5 = 7 chocolate chips per cookie

15 x 7 = 105

100>105

Answer:

just as you can add the same value to each side of an equation without changing the meaning of the equation, you can subtract the same value from each side of an equation.

by-step explanation:

x+7=42

Since 7 is being added to the variable, subtract 7 to isolate the variable.

To keep the equation balanced, subtract 7 from both sides of the equation.

x+7=42

-7 over x+0

-7 over 35

so answer is 35

Answer:

42 easy :)

Step-by-step explanation:

Answer:

A, B, and D.

Step-by-step explanation:

A. represents the Holy Trinity. Christians have the belief that the whole universe was created by God.

B. represents the 3rd day after Jesus died, but then he rose. This is the day that Christian's celebrate as Easter.

D. represents the deliverance from sin and its consequences, believed by Christians to be brought about by faith in Christ.

Hope this helps! :)

God Bless

Answer:

I couldn't tell which angle you meant, so the two missing angles are Q = 56 and S = 68

Step-by-step explanation:

Q = 180 - 124

Q = 56

56 (angle Q) + 56 (angle R) = 112

S = 180 - 112

S = 68

Answer:

Formula of circumference: pie(use 3.14 or 22/7) x radius (half of diameter or already given radius) x 2

100 + 100 = 200.

Half of 50(diameter) is 25(new radius). 25(radius) x 3.14(pie) x 2(it always will be there when finding circumference) = 157.

200 + 157 is = 357.

357 is your answer.

Answer:

Each cube with side lengths of 1/4 have a volume of (1/4)3 which means each cube's volume is 0.015625 cubic units. To find how many cubes are needed to fill the prism, divide 3 cubic units by 0.015625 cubic units. Your answer will be 192 cubes.
