Answer:

73.12 in.²

Step-by-step explanation:

The entire area is made up of a semicircle and a rectangle. We find both areas and add them.

total area = area of semicircle + area of rectangle

total area = (1/2)πr² + length × width

total area = 1/2 × 3.14 × 4 in. × 4 in. + 8 in. × 6 in.

total area = 73.12 in.²

Answer :

3/4.

Explanation

Find the GCD (or HCF) of numerator and denominator

GCD of 45 and 60 is 15

Divide both the numerator and denominator by the GCD

45 ÷ 15

60 ÷ 15

Reduced fraction: 3/4

Therefore, 45/60 simplified to lowest terms is 3/4.

Hi! I hope you are enjoying your day!

In order to simplify this ratio (and 45:60 is a ratio), we should divide both sides of the ratio by 5 (because both 45 and 60 are evenly divisible by 5)

Divide:

9:12

Is the ratio in its simplest form? No.

Why?

Because 9 and 12 can be divided by 3:

3:4

Now the ratio IS in its simplest form.

Hence, the answer is

[tex]\boxed{\boxed{\bold{3:4}}}[/tex]

Hope everything is clear.

Answer:

x=-2

x=2

Step-by-step explanation:

We can think of this equation like a statement

"4 times what squared minus sixteen is equal to zero"

First, we need to rearrange the equation:

[tex]4x^2=16[/tex]

Now using our common knowledge, we know that 4 times 4 is equal to 16

now we have another statement:

"x times x is going to be equal to 4"

*Remember that the two numbers have to be the same since x is squared*

Again, we can use common knowledge and say that 2x2 is equal to 4

This means that x=2

Now when you square a variable, the variable can have to values, a positive, and a negative value

So in this case, the other value for x would be x=-2 since -2 squared is also equal to 4

So we can come to a conclusion that

x=2

AND

x=-2

Answer: x = 6

Step-by-step explanation:

1. Distribute

2. Subtract 4 from both sides of the equation

3. Simplify

4. Subtract 2x from both sides of the equation

5. Simplify

6. Divide both sides of the equation by the same term

7. Simplify

Hello, the answer would be X = 6

Answer:

x = -8

Step-by-step explanation:

[tex]\mathrm{Multiply\:both\:sides\:by\:}-3[/tex]

[tex]\left(-\frac{1}{3}\left(6x+18\right)\right)\left(-3\right)=10\left(-3\right)[/tex]

[tex]\mathrm{Simplify}[/tex]

[tex]6x+18=-30[/tex]

[tex]\mathrm{Subtract\:}18\mathrm{\:from\:both\:sides}[/tex]

[tex]6x+18-18=-30-18[/tex]

[tex]\mathrm{Simplify}[/tex]

[tex]6x=-48[/tex]

[tex]\mathrm{Divide\:both\:sides\:by\:}6[/tex]

[tex]\frac{6x}{6}=\frac{-48}{6}[/tex]

Step-by-step explanation:

1gram=5400

1kg=5400*1000 (1kg=1000gm)

=5400000

1quntal=5400000*100 (1quntal=100kg)

=540000000

1ton=540000000*10 (1ton=10 quntal)

=5400000000

Answer:

175/24

Step-by-step explanation:

First change mixed fraction to improper fraction.

1¾= (1×4+3)/4

= 7/4

4⅙= (4×6+1)/6

= 25/6

now multiply the nominators (numbers on the top) and then the denominators (numbers on the bottom)

I.e

7/4 × 25/6

= 7×25/4×6

= 175/24

it cannot be further simplified so 175/24 is the answer.

The number d is not a divisor of the integers 400, 366 and 213

The least possible value of d is 17

The numbers are given as:

400, 366 and 213

The divisor is given as: d

Where d > 1

To determine the least possible value of d, we make use of the following Python program, where comments are used to explain each action.

#This iterates from 2 to the smallest number of the three divisors

for d in range(2,213):

   #This checks for the common remainder

   if(400%d == 366%d) and (400%d == 213%d):

       #This prints the value of d, when the smallest remainder of all three integers is determined

       print(d)

At the end of the program, the output is 17

Hence, the least possible value of d is 17

Answer:

80

Step-by-step explanation:

If 16 is %20 then it represents 1/5 of the class. Multiply 16 x 5 = 80

To earn at least $3,200 in revenue, the ticket prices should be $10 or $40.

An equation is an expression that shows the relationship between two or more variables and numbers.

Revenue = number of tickets sold * price per ticket = (400 - 8p)p

Revenue = 400p - 8p²

For no revenue:

400p - 64p² =  0

p = $0 or p = $50

For revenue of atleast 3200:

400p - 8p² =  3200

p = $10 or p = $40

To earn at least $3,200 in revenue, the ticket prices should be $10 or $40.

Answer: 227 degrees

Step-by-step explanation:

Answer: I don't know

Step-by-step explanation:  Use the fact that 180° is equivalent to \pi  radians as a conversion factor: 1=\frac{\pi \, \text{rad}}{180^{\circ}}=\frac{180^{\circ}}{\pi \, \text{rad}}.

225^{\circ}=225^{\circ}·\frac{\pi }{180^{\circ}}=\frac{5\pi }{4} rad

\frac{5\pi }{3} rad = \frac{5\pi }{3}·\frac{180^{\circ}}{\pi }=300^{\circ}

Answer:

8.49inches(incorrect options)

Step-by-step explanation:

the diagonal in a square divided the square into 2 and equal right- angled triangles.

to find the length of the diagonal of the square pick one of the triangles and find the length using pythagoras theorem.

having sketch a diagram. the length of the diagonal becomes the hypotenuse and the the two sides of the square becomes the opposite and adjacent side.

hyp²=opp²+adj²

L²=6²+6²

L²=72

L=8.49inches
