Answer:

B

Step-by-step explanation:

Answer: Y is equal to 1

Step-by-step explanation:

If any variable is by itself like for example 1 + y, that variable would equal one because it's all by itself so it attomatically equals 1. But if the variable was with another number like 1y, then it would mean you have to multiply it by whatever why would equal.

Hope This Helps!

Answer:

20

Step-by-step explanation:

Answer:

1080 cm²

Step-by-step explanation:

Surface area pyramid shape = 2(15*12) = 360

Surface area cube = 5( 12 x 12) = 720

360 + 720 = 1080 cm²

Answer:

The total area of the figure is equal to 705600

[tex](x + 5)(x + 2)[/tex]

Use the algebraic identity,

[tex](x + a)(x + b) \\ = {x}^{2} + (a + b)x + ab[/tex]

Now,

a = 5

b = 2

Substitute the values of a & b in the identity & solve the equation.

[tex] {x}^{2} +( a + b)x + ab \\ = x {}^{2} + (5 + 2)x + 5 \times 2 \\ = {x}^{2} + 7x + 10[/tex]

[tex]✎ \: (x + 5)(x + 2) = {x}^{2} + 7x + 10[/tex]

Answer:

It would be 24(π)

Step-by-step explanation:

This is due to the circumfenrece equation for a circle being (π)D, with D as the diameter which is 2x the radius, so 12x2=24.

After this, it is 24(π), though leave it at there since it is meant to be written in terms of it. You're now done!

Step-by-step explanation:

Step-by-step explanation:

angle(A+B+C)=180°{sum of angle of triangle}

C=180°-135°

C=45°

now,

sin theta=p/h

sin 45°=10/AC

1/√2=10/AC

AC=10√2

Ac=14.14

Answer:

70 mm

Step-by-step explanation:

Use PYTHAGOREAN THEOREM: a^2+b^2=c^2

42^2 + 56^2 = c^2

1764 + 3136 = c^2

4900=c^2

square root of 4900 is 70

so, the final answer is 70 mm

Step-by-step explanation:

Divide each term by 3 and simplify. x = 2

Answer:

slope = 4

Step-by-step explanation:

Calculate the slope m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (0, 0) and (x₂, y₂ ) = (1, 4 ) ← 2 points on the line

m = [tex]\frac{4-0}{1-0}[/tex] = [tex]\frac{4}{1}[/tex] = 4

Answer:

28π

Step-by-step explanation:

Hi there!

I believe your answer is:  

1.5 square meters

»»————-　★　————-««  

Here’s why:  

As given in the question you have asked, the surface area of a cube can be found with:

[tex]SA=6s^2\\\\SA - \text{Surface Area}\\\\S- \text{A given side length.}[/tex]

⸻⸻⸻⸻⸻

We are given the side length of 0.5 meters. This means that we have to substitute the variable 's' for '0.5' to find the surface area.

⸻⸻⸻⸻⸻

[tex]\boxed{\text{Surface Area of a cube with a side length of 0.5 meters:}}\\\\------\\\\SA= 6(0.5)^2\\\\\rightarrow SA=6(0.25)\\\\\rightarrow \boxed{SA=1.5}\\\\------[/tex]

⸻⸻⸻⸻⸻

[tex]\text{The surface area of the cube should be }\boxed{\text{1.5m}^2\text{.}}[/tex]

All of the above

Step-by-step explanation:

Answer:

it A

Step-by-step explanation:

The value of x in the circle is 13.

Option C is the correct answer.

A circle is a two dimensional figure with a radius and circumference of 2pir.

The area of a circle is πr².

We have,

A chord is a line segment connecting two points on a circle.

A chord is different from a diameter, which is a chord that passes through the center of the circle.

The chords in a circle are all the same with the same length.

From the given diagram,

There are two chords.

This can be written as:

(15 + 8) = 23 makes one chord.

(10 + x) makes one chord.

Now,

23 = 10 + x

Solve for x.

23 = 10 + x

23 - 10 = x

x = 13

Thus,

The value of x in the circle is 13.
