Does side lengths 2, 5 and 7 form a right triangle

Answer:

49π cm²

Step-by-step explanation:

Diameter (d) = 14 cm

Radius (r) = d/2 = 14/2 = 7 cm

Area of a circle

= πr²

= π × (7)²

= 49π cm²

Hope it helps ⚜

Information provided with us :

What we have to calculate :

Performing Calculations :

Here we would be first calculating the radius of the given circle. As we know that radius of the circle is calculated by the formula,

Putting the values,

=> r = 14 / 2

=> r = 7

Therefore, radius is of 7 cm.

Now, heading up to calculate the area of circle.

Formula,

Putting the values in the formula,

=> A = 22/7 (7)²

=> A = (22/7) × 7 × 7

=> A = 22 × 7 × 7 / 7

=> A = 22 × 49 / 7

=> A = 22 × 7

=> A = 154 cm²

Answer:

64

Step-by-step explanation:

a = 235

b = 299

d (difference) = b - a

d = 299 - 235

d = 64

Solve the expression:

[tex] \frac{3}{5} x - 4 = 0 \\ + 4 \\ \frac{3}{5} x = 4 \\ \times \frac{5}{3} \\ x = 4( \frac{5}{3}) \\x = \frac{20}{3} \\ x = 6 \frac{2}{3} [/tex]

Step-by-step explanation:

By getting the exponential decay that models the situation, we will see that after 8 weeks she uses 0.12 cups.

We know that the first week, she uses 2 cups of sugar, and each week she uses removes one-third of what she used the previous week.

Then the second week she uses:

S₂ = 2 cups - (1/3)*(2 cups) = 2 cups*(1 - 1/3) = 2 cups*(2/3)

The third week she uses:

S₃ = 2 cups*(2/3) - (1/3)*2 cups*(2/3) = 2 cups*(2/3)^2

You already can see the pattern, at week x, she will use:

Sₓ = (2 cups)*(2/3)^(x - 1)

This is an exponential decay.

To get how much sugar does she uses after 8 weeks, we just replace x by 8 in the above equation:

S₈ = (2 units)*(2/3)^(8 - 1) = 0.12 cups of sugar.

The equations that describe the given circles are:

x^2 + y^2 = 4

x^2 + y^2 = 64

For a circle of radius R, centered at the point (a, b), the equation is:

(x - a)^2 + (y - b)^2 = R^2

In this case, we have two circles, both centered on (0, 0), but one has a radius of 2 units and the other a radius of 8 units, then we have two equations:

x^2 + y^2 = 2^2 = 4

x^2 + y^2 = 8^2 = 64

These are the two equations that describe the given circles.

Answer:

Lets say we have (-1)^(1.5)

Step-by-step explanation:

(-1)^(1.5) = (-1)^(3/2)

= (√(-1))^3 which has no solution in the real number field, as √(-1) does not exist.

In the complex number field √(-1) = i, and (-1)^(1.5) = i^3 = -i.

2) t + s = 30

No. 1 is because each tumbler is $10 making 10t and each hat is $5 making 5s and the total sales is $190

No. 2 is because the total tumblers and hats sold add up to 30

There are 60 minutes in an hour, means that Sal's pizza shop can make 28 pizzas an hour. Multiply this by 4 to get 112

Answer:112

Step-by-step explanation: I got you Breh

You see first you divide 4 hours by 15 minutes and you get 16 minutes.

To confirm that you can do 16 x 15 and it would be 240, and 4 hours is 240 miniutes.

Now you multiply 16 by 7 and you get 112

Answer:

1 1/2

Step-by-step explanation:

Answer: Assume π = 3.14(rounded upto two decimal point)

Case I. 1 year = 365 days

2 years = 730 days

3 years = 1095 days

And .14 years = 51 days 2 hours 24 minutes

So, 3.14 years = 1146 days 2 hours 24 minuts.

Now, suppose you born in a leap-year.

Case II. 1 year = 366 days

2 years = 732 days

3 years = 1098 days

and .14 years = 51 days 5 hours 45 minutes 36 seconds

Then, 3.14 years = 1149 days 5 hours 45 minuts 36 seconds

So, yes, it is possible to be exactly π years old. At exactly 1146 days 2 hours 24 minutes or 1149 days 5 hours 45 minutes 36 seconds (in case of a leap-year born), we could have celebrate at our π years birthday.

Answer:

a=245 s=315

Step: Solve a+s=560 for a:

a+s=560

a+s=560(Add -s to both sides)

a=−s+560

Step: Substitute −s+560 for a in 8a+3s=2905:

8a+3s=2905

8(−s+560)+3s=2905

−5s+4480=2905(Simplify both sides of the equation)

−5s+4480=2905(Add -4480 to both sides)

−5s=−1575

−5s=−1575(Divide both sides by -5)

s=315

Step: Substitute 315 for s in a=−s+560:

a=−s+560

a=−315+560

a=245

Answer: Joining a gang will not give you more protection; it could enhance your chance of being targeted as a victim. Gang members make far less money than those who do not join gangs. Gang members usually don't get a good education, making it hard to find a good job. Gang involvement increases your risk of being arrested, having to go to court, being put on probation or parole, being jailed, injured, or even killed. Being a gang member is a dangerous thing. Often, members realize this once they have joined the gang and want to leave. It is never easy to leave a gang because as a member you have information that could be shared with authorities like the police – and as a result, get the gang members in trouble. You would always be getting in trouble with the law because you would apart of a gang group. Gangs often steal, break in peoples houses, break in to their cars and etc. Gang members leave you to take the blame so the other ones would not get caught and go to jail. Being in a gang is really bad for you because if you did didce to leave the gang then they might come and kill you and your family because they have no respect for other people.
