Answer:

c=9.5 centimeters

Step-by-step explanation:

a^2+b^2=c^2

9^2+3^2=c^2

90=c^2

c=[tex]\sqrt{90}[/tex]

c=9.487

c=9.5

In order to find the answer, we need to multiply 15 x 12 then find the exponent based on the object shape (2D/3D).

15 x 12 = 180.

If the object is 2D, the exponent is 2 (squared). If the object is 3D, the exponent is 3 (cubed). We can tell that the object is 2D, so the exponent is 2.

The answer is 180^2, or 180 squared.

I was hoping that you'd give me Brainiest as I'm trying to rank up. If you want to, please do!

Answer:

The answer is 180 squared.

1.  solid and liquid

2. Evaporation changes liquid water to water vapour.

for #1: for example, it's raining, when it rains, the rain is water (liquid).

Or it's snowing, the snow is solid.

for #2: for example, when you are making tea, you need hot water, so you add heat, then the water lessens because it's transforming to gas, and sometimes you can see it.

1. solid and liquid

2. water vapor (gas)

Step-by-step explanation:

hey take a deep breath! you got this!

it's really simple if you use the format PEMDAS

P- parentheses

E-exponents

M-Muliplication

D-divison

A-addition

S-subtraction

or mostly used

P

E

M or D

A or S

(depends from which side just start Ex 2-1+8 you wouldn't do the plus first but the subtraction because we're going left to right. If it's 2x8-6+10 then we do multiplication first cause that step comes first, the minus then addition! hope that isn't to confusing!)

ok so our equation is 20÷(5x2/5)+3

whats our first step? remember PEMDAS!

Its Parenthesis! so first we do the equation (5x2/5)

since multiplication and division are in the same "category" we go left to right

so first we do 5x2=10 and then we do 10/5 which is equal to 2!

ok now we add back the rest of our equation!

20÷2+3 since we already solved the Parenthesis

now what come first? division or addition?

its division because.. once again... PEMDAS!!

So now we do 20÷2 which is equal to 10!

now whats left is to add 3!

and 10+3 is equal to .... 13!!!

I know it seems like a lot but you'll get the hang of it! just take it easy and take your time :)

The expression that is equivalent to the expression, [tex](\frac{4m^5n^2}{m^2n} )^3[/tex] is the expression, [tex]64m^9n^3[/tex].

If two expressions are equivalent to each other, it means the value of each of them are the same when simplified or evaluated in their simplest form.

Given the expression,

[tex](\frac{4m^5n^2}{m^2n} )^3[/tex]

Evaluate the expression in its simplest form

[tex](\frac{4m^5n^2}{m^2n} )^3 = (4m^3n^1)^3[/tex]

Multiply the exponents in the bracket by the one outside, then find the cube of 4.

[tex]64m^9n^3[/tex]

Therefore, [tex](\frac{4m^5n^2}{m^2n} )^3[/tex] is equivalent to [tex]64m^9n^3[/tex].

Answer:

We are given the initial price of a car and we are also told that the car sold for a 15% profit which means that the price that the car was sold for is 15% more than it's initial price.  This is just a simple multiplication problem which we multiply the initial price by the total percentage plus 0.15

[tex]Sold\ Price = Initial\ Price *(Total\ Percentage+Profit\ Percentage)[/tex]

[tex]Sold\ Price = \$5200*(1+0.15)[/tex]

[tex]Sold\ Price = \$5200*(1.15)[/tex]

[tex]Sold\ Price = \$5980[/tex]

Capacity means the volume of a solid shape.

To calculate the capacity of the tank, we use the formula below.

Note: When the water from the 8 small containers is poured into the tank that was initially half full, becomes 1.4 full that means the water from the 8 small containers fills the tank 0.9

Step-by-step explanation:

y = 5x² - 17x - 12

to find the roots let y = 0 , that is

5x² - 17x - 12 = 0

Factorising the quadratic

consider the factors of the product of the coefficient of the x² term and the constant term which sum to give the coefficient of the x- term

product = 5 × - 12 = - 60 and sum = - 17

the factors are - 20 and + 3

use these factors to split the x- term

5x² - 20x + 3x - 12 = 0 ( factor first/second and third/fourth terms )

5x(x - 4) + 3(x - 4) = 0 ← factor out (x - 4) from each term

(x - 4)(5x + 3) = 0

equate each factor to zero and solve for x

x - 4 = 0 ⇒ x = 4

5x + 3 = 0 ⇒ 5x = - 3 ⇒ x = - [tex]\frac{3}{5}[/tex] = - 0.6

roots are (4, 0 ) and (- 0.6, 0 )

Quadratic formula : ax² + bx + c = 0 where a ≠ 0

The number of real-number solutions (roots) is determined by the discriminant (b² - 4ac) :

The roots of the equation are determined by the following calculation:

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

Here, we have :

1) Calculate the discriminant :

b² - 4ac ⇔ 2² - 4(1)(-8) ⇔ 4 - (-32) ⇔ 36

b² - 4ac = 36 > 0 ; The equation admits two real-number solutions

2) Calculate the roots of the equation:

▪️ (1)

[tex]x_1 = \frac{ - b - \sqrt{ {b}^{2} - 4ac} }{2a} \\ \\ x_1 = \frac{ - 2 - \sqrt{36} }{2(1) } \\ \\ x_1 = \frac{ - 2 - 6}{2} \\ \\ x_1 = \frac{ - 8}{2} \\ \\ \blue{\boxed{\red{x_1 = -4}}}[/tex]

▪️ (2)

[tex]x_2 = \frac{ - b + \sqrt{ {b}^{2} - 4ac } }{2a} \\ \\ x_2 = \frac{ - 2 + \sqrt{36} }{2(1)} \\ \\ x_2 = \frac{ - 2 + 6}{2} \\ \\ x_2 = \frac{4}{2} \\ \\ \red{\boxed{\blue{x_2 = 2}}}[/tex]

Answer:

65

Step-by-step explanation:

Angle FGH = x

Angle FGJ = 25

Angle JGH = 40

Angle FGH = Angle FGJ + Angle JGH

                x = 25 + 40

                x = 65

The value of x in the diagram is 65.

The angles between two lines are the angles formed by two intersecting lines, measured in degrees or radians.

Several different types of angles can be formed between two lines, including acute angles, right angles, and obtuse angles.

We have,

From the diagram,

∠JGH = 40

∠FGJ = 25

Now,

∠JGH + ∠FGJ = x

So,

40 + 25 = x

Solve for x.

x = 40 + 25

x = 65

Thus,

The value of x in the diagram is 65.
