= 5.66 (3 s.f.)

By using the Pythagorean theorem, we will see that the length of DF is 5.7 units.

We can make a right triangle with the sides: DE, FE, and DF.

Such that we know that:

DE = FE = 4

These two are the cathetus of the right triangle.

Then DF is the hypotenuse.

Now, remember the Pythagorean theorem, it says that the sum of the squares of the cathetus is equal to the square of the hypotenuse, then we have:

(DE)^2 + (FE)^2 = (DF)^2

4^2 + 4^2 =(DF)^2

√32 = DF = 5.7

The length of DF is 5.7 units.

Multiplication and division both need to have a common denominator or else you would get an incorrect answer. Dividing two fractions is the same as multiplying the first fraction by the reciprocal of the second fraction. The first step to dividing fractions is to find the reciprocal (reverse the numerator and denominator) of the second fraction. Next, multiply the two numerators. Then, multiply the two denominators."

The  Volume of cubical box is 15.625 ft³.

The Volume of Cuboidal box is 843.75 ft³

Volume is a term used in mathematics to describe how much three-dimensional space an item or closed surface occupies.

Given:

Cube: edge = 2.5 feet

Cuboid: l = 7.5 ft, w= 15 feet, h= 7.5 feet

So, Volume of cubical box

= l³

= 2.5³

= 15.625 ft³

and, Volume of Cuboidal box

= lwh

= 7.5 x 15 x 7.5

= 843.75 ft³

Answer:

The volume is 12!

Step-by-step explanation:

Please let me know if im correct or not! but i belive i am.

Answer:

12in³

Step-by-step explanation:

V = (B * h) / 3, where B is the area of the base and h is the height.

The base is a rectangle, so it's easy to find it's area:

B = 3 * 2 = 6

Now just find the volume:

V = (6 * 6) / 3 = 36 / 3 = 12in³

Answer:

a. 52%

b. 56%

Step-by-step explanation:

a. 43+87=130

130/250×100

=52

b. 87+53=140

140/250×100

=56%

By, Cross multiplying, we get

[tex]⇢2x(x - 1) = (2x - 1)(x + 2)[/tex]

[tex]⇢2 {x}^{2} - 2x = 2x(x + 2) - 1( x+ 2)[/tex]

[tex]⇢2 {x}^{2} - 2x = 2 {x}^{2} + 4x - x - 2[/tex]

Here, [tex]2 {x}^{2} [/tex] from both sides will get cancelled

[tex]⇢ - 2x - 3x = - 2[/tex]

[tex] ⇢x = \frac{ - 2}{ - 5} [/tex]

[tex] ⇢ \underline { \boxed{ x = \frac{2}{5} }} [/tex]

Answer:

[tex]x=\frac{2}{5}[/tex]

Step-by-step explanation:

[tex]\frac{2 x}{x+2}-\frac{x}{x-1}=1[/tex]

[tex]\begin{aligned} & \Leftrightarrow \frac{2 x(x-1)}{(x+2)(x-1)}-\frac{x(x+2)}{(x-1)(x+2)}=1 \\& \Leftrightarrow \frac{2 x^{2}-2 x}{(x+2)(x-1)}-\frac{\left(x^{2}+2 x\right)}{(x+2)(x-1)}=1 \\& \Leftrightarrow \frac{2 x^{2}-2 x-\left(x^{2}+2 x\right)}{(x+2)(x-1)}=1 \\& \Leftrightarrow \frac{2 x^{2}-2 x-x^{2}-2 x}{(x+2)(x-1)}=1 \\& \Leftrightarrow \frac{x^{2}-4 x}{(x+2)(x-1)}=1 \\\end{aligned}[/tex]

[tex]\begin{aligned}& \Leftrightarrow x^{2}-4 x=(x+2)(x-1) \\& \Leftrightarrow x^{2}-4 x=x^{2}-x+2 x-2 \\& \Leftrightarrow x^{2}-4 x=x^{2}+x-2 \\& \Leftrightarrow-4 x=x-2 \\& \Leftrightarrow 5 x=2\end{aligned}[/tex]

Answer:

<1=28, <2=62

Step-by-step explanation:

You know that the large triangle is 180 and there is a smaller triangle that is also 180. You are also provided an angle is 90 and another is 62.

90+62=152.

180-152=28. So, angle 1=28.

28+90=118.

180-118=62

The value of measure of angle ∠1 is,

⇒ ∠1 = 28°

And, The value of measure of angle ∠2 is,

⇒ ∠2 = 118°

An angle is a combination of two rays (half-lines) with a common endpoint. The latter is known as the vertex of the angle and the rays as the sides, sometimes as the legs and sometimes the arms of the angle.

Now, For definition of angles of triangles;

We get;

⇒ 62° + 90° + ∠1 = 180°

⇒ 152° + ∠ 1 = 180°

⇒ ∠ 1 = 180° - 152°

⇒ ∠1 = 28°

And, Sum of two interior angles of triangle is equal to an exterior angle of triangle.

Hence, We get;

⇒ ∠2 = ∠1 + 90°

⇒ ∠2 = 28° + 90°

⇒ ∠2 = 118°

Thus, The value of measure of angle ∠1 is,

⇒ ∠1 = 28°

And, The value of measure of angle ∠2 is,

⇒ ∠2 = 118°
