Step-by-step explanation:

answer is 91.2 square centimeters

Answer:

0.6 x 94, 60/100 x 94

Step-by-step explanation:

0.6 = 60% of 1.

60/100 also = 60% of 1

Answer:

Step-by-step explanation:

As here,

3 cm + 6 cm = 9cm. = 9cm

And as we know,

According to Triangle Inequality Property,

Measurement of any two sides of a triangle is always greater than the third side.

But here,

Sum of two sides is same as the third side,

So,

Option D is the required answer.

Answer:

The equation of the circle is;

(x - [(-1))² + (y - [7])² = 8

Step-by-step explanation:

The given coordinates of the points P and Q are;

P = (-3, 5) and Q = (1, 9)

To find the equation of the circle that has segment PQ as a diameter

The equation of a circle is (x - h)² + (y - k)² = r²

Where;

(h, k) = The coordinates of the center of the circle

r = The radius of the circle

Given that segment PQ is the diameter of the circle, we have;

The center of the circle, O = The midpoint of PQ

The coordinates of the midpoint of segment PQ, O = ((-3 + 1)/2, (5 + 9)/2) = (-1, 7)

∴ The coordinates of the center of the circle, O = The coordinates of the midpoint of segment PQ = (-1, 7)

Therefore;

h = -1, k = 7

From PQ = The diameter of the required circle, we also have;

The length of PQ = 2 × (The radius of the circle) = 2 × r

The length of segment PQ = √((1 - (-3))² + (9 - 5)²) = √32 = 4·√2

Therefore;

The length of PQ = 4·√2 = 2 × r

r = (4·√2)/2 = 2·√2

r = 2·√2

r² = (2·√2)² = 8

r² = 8

The equation of the circle is therefore;

(x - h)² + (y - k)² = r²

(x - (-1))² + (y - 7)² = 8.

x = 4

Answer:

Look below

Step-by-step explanation:

9 would be a solution of the inequality x>5 because x can represent any number, but because there is a > between x and 5, that means that whatever number x represents is greater than 5, and because 9 is greater than 5, it is a solution to the inequality.

Answer:

arc PSQ is the name

I believe it would just be called a semi circle.

Major arcs are > 180°

Minor arcs < 180°

Exactly 180°, I'm not sure

Step-by-step explanation:

heyy

so a Pythagoras theorem always works on a right angle triangle only

the longest side that is the side not involved in the right angle triangle is called the hypotenuse

the other two involved sides are called legs

so we say one leg is a

other leg is b

and hypotenuse is c

the formula is a²+b²=c²

so if a= 4cm

b=3cm

then find c

so a²+b²=c²

so 16+9=25

so square root of 25 is 5²

so c is equal to 5 cm

also if you want to check if the triangle is a right angled triangle then we should perform this theorem in which all three values will be given but you just need to solve and check if it satisfies

thanks for asking

pls gimme brainliest I need it

Answer:

bh/2

Step-by-step explanation:

So first, you have to multiply the base times height and you get a value. Then, you divide the value by 2. For example, a triangle that has a base of 3 and height of 4, you would multiply 4x3 which is 12 and then divide by 2 which is 6. Hope this helps :)

You can also just add 0 if there isn't a decimal point

13.5*10=135                        move the decimal one space to the right

Answer:

3c2  + 4c − 15

Step-by-step explanation:

I tried my best if this is correct please sub to m YT I am a aspiring small creator

my YT is YoungGodlyFN.

Applying distributive property, the product of the given expression,

(3c-5)(c+3) is  3c² + 4c - 15.

In mathematics, the outcome of multiplying two integers is their product.

The given expression is,

(3c-5)(c+3)

Expanding this expression as,

3c(c+3) - 5(c+3)

Distribute the number inside the bracket we get,

3c² + 3x3c - 5c - 5x3

⇒ 3c² + 9c - 5c - 15

Combine like terms,

3c² + (9 - 5)c - 15

⇒ 3c² + 4c - 15

Thus,

(3c-5)(c+3) = 3c² + 4c - 15

Hence,

The product of the given expression is  3c² + 4c - 15.

Answer:

n = 65; p = 0.8

Step-by-step explanation:

The sample size (n) and sample proportion () can a normal curve be

used to approximate the sampling distribution is n = 65, p = 0.8.

The correct option is D.

According to the Central Limit Theorem, the shape of sample distribution of sample proportions with a population proportion, 'p' is normal

If n·p ≥ 10 and n·(1 - p) ≥ 10.

n = 65, p = 0.8

∴ n·p = 65 x 0.8 = 52 > 10

n·(1 - p) = 65 × (1 - 0.8) = 13 > 10

For n = 90, p = 0.9, n·(1 - p) = 18 > 10, a normal distribution can be used to approximate the sampling distribution.
