mZ4 = 30° what is mZ8?​

Answer:

$137.82

Step-by-step explanation:

The volume of a hemisphere stone is given by the volume of a half-sphere:

Volume = (2/3) * pi * radius^3

If the diameter is 16 inches, the radius is 16/2 = 8 inches, so the volume is:

Volume = (2/3) * pi * 8^3 = 1072.33 in3

We need a total of 8 stones, so the total volume is:

Total Volume = 8 * 1072.33 = 8578.64 in3

The density of clay is 0.0035 pounds per cubic inch, so the total weight of the 8 stones is:

Weight = Total Volume * density = 8578.63 * 0.0035 = 30.0252 pounds

Finally, if the price of each pound of clay if $4,59, the final price is:

Price = 30.0252 * 4.59 = $137.82

Answer:

540°

Step-by-step explanation:

The sum of the interior angles of a polygon is

sum = 180° (n - 2) ← n is the number of sides

A pentagon has n = 5, thus

sum = 180° × 3 = 540°

Step-by-step explanation:

area of a square =length*width whereas they are supposed to be of the same measurements

The value of the variable 'x' will be 85. Then the correct option is A.

The polygonal shape of a triangle has a number of sides and three independent variables. Angles in the triangle add up to 180°.

The definition of simplicity is making something simpler to achieve or grasp while also making it a little less difficult.

The equation is given below.

x + 40 + 55 = 180

Simplify the equation, then the value of 'x' is given as,

x + 40 + 55 = 180

x + 95 = 180

x = 180 - 95

x = 85

The value of the variable 'x' will be 85. Then the correct option is A.

Answer:

g(-3)=10

Step-by-step explanation:

We want to find what g(x), or y is, when x is equal to -3.

g(x)== x² + 1

x= -3

Substitute -3 in for x.

g(-3)=(-3)²+1

Evaluate the exponent first. -3² is equivalent to -3*-3, which is equal to 9.

g(-3)=9+1

Add 9 and 1

g(-3)=10

Answer:

Step-by-step explanation:

g(x)=x^2+1

at g(-3) = (-3)^2+1

=9+1=10

Answer:

x = [tex]\frac{-1}{4} + \frac{1}{4} \sqrt{29}[/tex]

Step-by-step explanation:

For this equation: a=4, b=2, c=-7

4x²+2x+−7=0

Step 1: Use quadratic formula with a=4, b=2, c=-7.

x=  [tex]\frac{-b + \sqrt{bx^{2}-4ac } }{2a}[/tex]

x = −(2)±√(2)2−4(4)(−7)  ÷ 2(4)

x = −2±√116   ÷ 8

x = [tex]\frac{-1}{4} + \frac{1}{4} \sqrt{29}[/tex]

250.5 - 35m = 300 - 45.25m

Complete question:

Which equation can be used to find m, the number of months it will take for both accounts to have the same amount of money?

250.5 + 35m = 300 + 45.25m

250.5 – 35m = 300 – 45.25m

250.5m – 35 = 300m – 45.25

250.5m + 35 = 300m + 45.25

Step-by-step explanation:

For The International Business Club: y = 250.50 - 35m,  

For The Future Agricultural Leaders Club: y = 300 - 45.25m.

So the answer is 250.5 - 35m = 300 - 45.25m

250.5 – 35m = 300 – 45.25m

Explanation:
It's this one because the initial for international Business Club is $250.50 and their monthly spending is $35, and for Future Agricultural Leaders Club their initial is $300 and their monthly spending is $45.25

So, the equation would be 250.5 – 35m = 300 – 45.25m

Answer:

6 full bags of rice.

0.4 kg of rice will be left.

Step-by-step explanation:

The man can carry a max of 160 kg.

1 bag of rice weighs 25 kg.

160/25 = 6.4

He can carry 6 full bags of rice.

Yes, there will be rice left.

0.4 kg of rice will be left.

Answer:

He can carry 6 whole 2/5 of the rice and 3/5 of rice in one bag would be left.

Step-by-step explanation:

Man can carry = 160 kg

1 bag of rice = 25 kg

He can carry = [tex]\frac{160}{25}[/tex]

=> [tex]6\frac{2}{5}[/tex]

Identify the opposite of 5 on the number line.

✔ –5

Using your results, which statement is true?

Since –2 is further

✔ right on the number line, –2 > –5

.

this is the answer

The correct state would be negative 2 is greater than negative 5.

The opposite of the numbers can be obtained changing the positive numbers to negative equivalent of the number as follows;

From the initial given expression, 2 < 5, that is 2 is less than 5.

From the opposite numbers, -2 > - 5, that is negative 2 is greater than negative 5.

Thus, the correct state would be negative 2 is greater than negative 5.

Answer:

1)The ball hits the ground after 3 seconds.

2)The maximum height of the ball is 49 feet

3)It takes 1.25 seconds to reach its maximum height

Step-by-step explanation:

Height of building = 40 feet

We are given that A ball is thrown straight up from the top of building with an initial speed of 24 feet per second.

So, The height of the ball as a function of time can be modeled by: [tex]h(t)=-16t^2+40t+24[/tex]

1)After how many seconds the ball hit the ground.

Substitute h(t)=0

So,[tex]-16t^2+40t+24=0\\-2t^2+5t+3=0\\2t^2-5t-3=0\\2t^2-6t+t-3=0\\2t(t-3)+1(t-3)=0\\(2t+1)(t-3)=0\\t=\frac{-1}{2} , 3[/tex]

Since time cannot be negative

So,the ball hits the ground after 3 seconds.

2)What is the maximum height of the ball?

It takes maximum height at vertex

Formula : [tex]t = \frac{-b}{2a}[/tex]

[tex]t=\frac{-40}{2(-16)}=1.25 seconds[/tex]

Substitute the value of t in function

[tex]h(1.25)=-16(1.25)^2+40(1.25)+24\\h(1.25)=49 feet[/tex]

So,the maximum height of the ball is 49 feet

3).How long did it take for the ball to reach its maximum height?

It takes 1.25 seconds to reach its maximum height

Answer:

-8/27

Step-by-step explanation:

Convert 2 1/4 into a improper fraction: 9/4

Rewrite the equation: -2/3 divided by 9/4

To divide fraction, multiply by the reciprocal of that fraction

Reciprocal of 9/4: 9/4

Multiply the fractions: -2/3 times 4/9

=-8/27

Answer:

-8/27

Step-by-step explanation:

-(2/3) ÷ (2 1/4 )   (convert 2 1/4 into improper fraction)

= -(2/3) ÷ (9/4)  (convert ÷ to x by taking the reciprocal of 9/4)

= -(2/3) x (4/9)

= -(2 x 4) / (3 x 9)

= -8/27

Answer: she begin with 6.

Step-by-step explanation:

At the beggining she had A books.

She sold half of that, so now she has A/2 books.

She bought 9, so now she has A/2 + 9 books,

And we know that A/2 + 9 = 11 books

So A/2 = 11 - 9 = 3

A = 2*3 = 6

So she started with 6 books

Answer:

She began with 4 books

Step-by-step explanation:

Let the original number of Jessi Comic books be x

When She sold half of the comic books, she has ( x - x/2) = x/2 left

When she bought 9 more, she has 11 in total. That is, x/2 + 9 = 11

x/2 = 11 - 9

x/2 = 2

x = 2 * 2

x = 4

She began with 4 books

Answer:

[tex]\frac{a}{1 +bc} = x[/tex]

Step-by-step explanation:

In this question, it appears that you need to solve this equation in terms of x.

Beginning with the equation a = x(1 + bc), we must isolate the 'x' variable and make an equation equivalent to 'x'. This can be done by:

a = x(1 + bc)

Divide (1 + bc) from both sides, giving you:

[tex]\frac{a}{1 +bc} = x[/tex]
