I NEED HELP ASAP!!!!!

please help out;

What is the surface area of this triangular prism?

Given:

[tex]d = 13.3\ in[/tex]

[tex]w = 11.3\ in[/tex]

[tex]d=\sqrt{w^2+h^2}[/tex]

To find:

The value of h.

Solution:

We have,

[tex]d=\sqrt{w^2+h^2}[/tex]

Substituting [tex]d = 13.3, w = 11.3[/tex], we get

[tex]13.3=\sqrt{11.3^2+h^2}[/tex]

Taking square on both sides.

[tex]176.89=127.69+h^2[/tex]

[tex]176.89-127.69=h^2[/tex]

[tex]49.2=h^2[/tex]

Taking square root on both sides, we get

[tex]\pm 7.01427=h[/tex]

[tex]h\approx \pm 7[/tex]

Height cannot be negative so [tex]h=7\ in[/tex].

Therefore, the correct option is A.

Answer:

If you multiply or divide both sides of an equation by the same negative number, the equation remains the same, but If you multiply or divide both sides of an inequality by the same negative number, the inequality reverses. !!!!!

Step-by-step explanation:

Answer:

The only difference is: If you multiply or divide both sides of an equation by the same negative number, the equation remains the same, but If you multiply or divide both sides of an inequality by the same negative number, the inequality reverses. !!!!!

Answer:

252 centimeters squared is the answer.

The area of the rectangle is 252 cm².

A rectangle is a plane shape that has pair of opposite sides and angles equal

To calculate the area of a rectangle, we use the formula below.

Formula:

Area of a rectangle(A) = Length(L)×Width(W).............. Equation 1

⇒ Let the length of the rectangle be x and the width of the rectangle be y.

If the length is decreased by 6 cm

And if the width is increased by 3 cm

Since the new length and the new width form a square,

Note: In a square, all sides are equal

Also, The area of the new square formed is smaller than the area of the rectangle by 27 cm²

Substitute these values of x in equation 2 into equation 3

Collect like terms

Substitute the value of y into equation 1 to get x

Hence, The area of the rectangle is 252 cm².

Area of triangle

a = 6 ft + 2 ft + 2ft = 10 ft

h = 12 ft

½ * 10 ft * 12 ft = 60 sq ft

Area of square :

a = 6 ft

6 ft * 6 ft = 36 sq ft

Area of this figure :

60 + 36 = 96 sq ft

Answer:

156 ft

Step-by-step explanation: (This does not seem to be in scale)

1. Split into one triangle and one square

2. Find triangle area

12 * 10 = 120 ft

3. Find square area

6 * 6 = 36 ft

4. Area = Atriangle + Asquare

120 + 36 = 156 ft

Step-by-step explanation:

58+264=322

Answer:

322 feet

Step-by-step explanation:

if the question was two positive heights, you would subtract, and you still do. we find how many inches my father is taller than me by subtracting my height from his, and the same applies to this, though the submarine, being below sea level is at a negative height. when you subtract a negative, it's the same as adding a positive.

264 - (-58)          

264 + 58 = 322

Answer:

$5520

Step-by-step explanation:

Given data

Principal=  $24000

Rate=10%

time= 2 years

Firstly, the compound interest is given as

A=P(1+r)^t

A=24000(1+0.1)^2

A=24000(1.1)^2

A=24000*1.21

A=$29040

The simple interest is given as

A=P(1+rt)

A=24000(1+0.1*2)

A=24000(1.2)^2

A=24000*1.44

A=$34560

Hence the difference is

=34560-29040

=$5520

Answer:

A

Step-by-step explanation:

Angle P is intercepted by two arcs.

SB and RQ.

We can use this theorem,

If two chords intersect inside a circle, then the measure of the angle formed is one half the sum of the measure of the arcs intercepted by the angle and its vertical angle.

So in other words,

[tex] \frac{80 + 150}{2} = rpq[/tex]

[tex]rpq = 115[/tex]
