Answer:

1160 cm^2

Step-by-step explanation:

Surface area=2(lw)+2(hl)+2(hw)

So, surface area=2(15x20)+2(8x15)+2(8x20)

=2(300)+2(120)+2(160)

=600+240+320

surface area=1160 cm^2.

The surface area of the cuboid is 1160 cm²

What is the surface area of cuboid?

The total surface area of the cuboid is given by the formula

Surface Area = 2 ( LH + LW + HW )

where ,

Length of the cuboid = L

Width of the cuboid = W

Height of the cuboid = H

Given data ,

Length of the cuboid L = 15 cm

Width of the cuboid W = 20 cm

Height of the cuboid H = 8 cm

Surface Area of the cuboid = 2 ( LH + LW + HW )

Substituting the values of L , H and W in the equation , we get

Surface Area of the cuboid = 2 ( ( 15 x 8 ) + ( 15 x 20 ) + ( 20 x 8 ) )

So ,

Total surface area of the cuboid = 2 ( 120 + 300 + 160 ) cm²

                                                      = 2 ( 580 ) cm²

                                                      = 1160 cm²

Hence , the Total surface area of the cuboid is 1160 cm²

Answer:

0.2

Step-by-step explanation:

6+4+3+2=total no of marble

=15

no of blue marble 3

[tex] \frac{3}{15} \\ = \frac{1}{5 } \\ = 0.2[/tex]

The probability that the marble is blue is 1/5 or 0.2.

Probability refers to potential. A random event's occurrence is the subject of this area of mathematics.

The range of the value is 0 to 1. Mathematics has incorporated probability to forecast the likelihood of various events.

The degree to which something is likely to happen is basically what probability means.

Given:

Red marbles= 6

Green marbles = 4

Blue marble = 3

Yellow marbles= 2

Total marbles= 15

So, the probability getting blue marble

= blue marble / total marble

= 3/15

= 1/5

Step-by-step explanation:

Answer:

[tex]x=12[/tex]

Step-by-step explanation:

Method 1: Pythagorean Theorem

We can use the Pythagorean Theorem to solve for [tex]x[/tex]. The Pythagorean Theorem states that in a right triangle, the sum of the squares of the legs' side lengths is equal to the length of the hypotenuse squared. Simply put, [tex]a^{2} +b^{2} =c^{2}[/tex], where [tex]a[/tex] and [tex]b[/tex] are the legs and [tex]c[/tex] is the hypotenuse. In this case, we know that [tex]a=x[/tex], [tex]b=9[/tex], and [tex]c=15[/tex], so we get:

[tex]a^{2} +b^{2} =c^{2}[/tex]

[tex]x^{2} +9^{2} =15^{2}[/tex] (Substitute [tex]a=x[/tex], [tex]b=9[/tex], and [tex]c=15[/tex] into [tex]a^{2} +b^{2} =c^{2}[/tex])

[tex]x^{2} +81 =225[/tex] (Simplify exponents)

[tex]x^{2} +81-81=225-81[/tex] (Subtract [tex]81[/tex] from both sides of the equation to isolate [tex]x[/tex])

[tex]x^{2} =144[/tex] (Simplify)

[tex]\sqrt{x^{2}} =\sqrt{144}[/tex] (Take the square root of both sides)

[tex]x=12,x=-12[/tex] (Simplify, remember that each positive number has two square roots: a positive one and a negative one)

In the context of the situation, we know that [tex]x=-12[/tex] is an extraneous solution because a polygon cannot have negative side lengths. Therefore, the final answer is [tex]x=12[/tex].

Method 2: Pythagorean Triples

Method 1 works, but there's an easier way to find the value of [tex]x[/tex]. If we look at the given lengths of [tex]9[/tex] and [tex]15[/tex], we can observe that this triangle is a [tex]3-4-5[/tex] right triangle enlarged by a scale factor of [tex]3[/tex], because [tex]3*3=9[/tex] and [tex]5*3=15[/tex]. The only side length that's missing is the [tex]4[/tex]. Therefore, [tex]x=4*3=12[/tex]. Hope this helps!

Answer:

Area = 144 inches2

or

Area = 1 feet2

Steps:

1.5 feet = 18 inches

Area =  l × w

=  8 × 18

=  144 inches2

or

8 inches = 0.66666666666667 feet

Area =  l × w

=  0.66666666666667 × 1.5

Answer:

Diameter:6.08

Radius=D/2=6.08/2=3.04

Step-by-step explanation:

Answer:

The radius is

[tex] \sqrt{29} [/tex]

The diameter is

[tex]2 \sqrt{29} [/tex]

Step-by-step explanation:

The area of the circle is represent as

[tex] a = \pi \times r {}^{2} [/tex]

Where r is the radius and a is the area. Since pi is a irrational number, we won't focus on doing nothing with that instead we just take the sqr root of both sides to find the r or radius.

[tex] \sqrt{29} [/tex]

Which is the radius and it cant be simplified so the radius is

[tex] \sqrt{29} [/tex]

The diameter is twice longer than the radius so we

[tex]2 \times \sqrt{29} [/tex]

Which is

[tex]2 \sqrt{29} [/tex]
