Answer:

In this rectangular prism, opposite sides are equal.

So if we find the 3 different sides, we would need to multiply those individual sides by 2 (because opposite sides are equal/have the same area) and then add them to get the surface area.

One side (the front and back side);

The width is 8 and the height is 7, so (8 x 7) = 56. Though, it's opposite side is the same as well so we multiply 56 by 2, (56 x 2) = 112

Second side (the left and right side);

The width is 18 and the height is 7, so (18 x 7) = 126. Though, it's opposite side is also the same as well, so we multiply 126 by 2, (126 x 2) = 252

Third side (the top and bottom side);

The width is 8 and the height is 18, so (8 x 18) = 144. Though, it's opposite side is also the same as well, so we multiply 144 by 2, (144 x 2) = 288

Now, we add all the areas we've gathered:-

112 + 252 + 288 = 652 square cm

Answer:

let s = number of buttons on a shirt

let j = number of buttons on a jacket

Create 2 equations from the given information:

Equation 1:  36s + 42j = 842

Equation 2:  6s + 7j = 137

If we multiply equation 2 by 6 we get:

⇒ 36s + 42j = 822

Comparing this with equation 1, we can see that the number of shirts and jackets is now the same BUT the number of buttons is different

Therefore, her hypotheses is incorrect and we cannot solve to determine the number of buttons on a shirt and/or jacket.

Answer:

D -2x-6

Step-by-step explanation:

We are given that the width of of a rectangular painting is 83 cm and it's area is 7719 cm² and we are asked to find it's length , as we know that the area of a rectangular shape is given by L×B. Where L is the length of the rectangular shape and B is the width/Breadth .Now , applying the same concept in our question we have ;

[tex]{:\implies \quad \sf L\times 83=7719}[/tex]

[tex]{:\implies \quad \sf L=\dfrac{7719}{83}}[/tex]

[tex]{:\implies \quad \sf L=93}[/tex]

[tex]{:\implies \quad \bf \therefore \quad \underline{\underline{Length=93\:\: cm}}}[/tex]

Answer:

h=39

Step-by-step explanation

V = [tex]\pi[/tex]r^(2) h

V = 10,000[tex]\pi[/tex]

radius = diameter / 2

diameter = 32

radius = 32/2

radius = 16

10,000[tex]\pi[/tex]=[tex]\pi[/tex](16)^(2)(h)

Simplify by dividing [tex]\pi[/tex] from both sides and evaluating 16^2

10,000=256h

Simplify again by dividing 256 from both sides to isolate h.

39.06 = h

Round to the nearest whole number:

39 inches.

Answer:

Average speed = 80km

Step-by-step explanation:

[tex]AS = \frac{480km}{6} \\ AS = 80km[/tex]

as means average speed

Sipho travelled 480km in 6 hours -> In an hour, Sipho travelled 1/6 of the distance.

So, in an hour, Sipho travelled : 480 x 1/6 = 80km

In an hour, he travelled 80km -> his average speed is 80km/h

Answer:

0.94

Step-by-step explanation:

Formula; P(AUB) = P(A) + P(B) - P(AB).

P(A) = 0.7

P(B) = 0.8

P(AB) = 0.56

=  0.7 + 0.8 - 0.56

=  0.94

Hence, P(A U B) = 0.94

[RevyBreeze]

Answer:

P(A ∪ B) = 0.94

Step-by-step explanation:

P(A) = 0.7

P(B) = 0.8

P (A ∩ B) = 0.56

P(A ∪ B) = P(A) + P(B) - (A ∩ B)

⇒ P(A ∪ B) = 0.7 + 0.8 - 0.56

⇒ P(A ∪ B) = 0.94

Answer:

(-1.25,-0.25).

Step-by-step explanation:

The length of the rectangle is 2.5 units. To find the point that is 2.5 units from (1.25,1), count 2.5 units to the left of the point. The x-coordinate will change and the y-coordinate will remain the same. This point is (-1.25,1).

The width of the rectangle is 1.25 units. To find the point that is 1.25 units from (1.25,1), count 1.25 units down from the point. The y-coordinate will change and the x-coordinate will remain the same. This point is (1.25,-0.25).

Answer:

75%

Answer:

[tex]y=3x^2+9x-30[/tex]

Step-by-step explanation:

To multiply [tex](3x+15)[/tex] with [tex](x-2)[/tex] we can use a method called the FOIL method. FOIL is an acronym standing for First, Outer, Inner, Last. This is the order in which we need to multiply. The first terms of each multiplier are [tex]3x[/tex] and [tex]x[/tex]. Therefore, we multiply these two terms to get [tex]3x^2[/tex]. The outer terms are [tex]3x[/tex] and [tex]-2[/tex]. Once again, we multiply these terms.

[tex](3x)(-2)=-6x[/tex]

Now, our equation looks like this: [tex]y=3x^2-6x[/tex]. We're not finished yet though. Next, we need to multiply the inner terms, [tex]15[/tex] and [tex]x[/tex]. This comes out as simply [tex]15x[/tex]. Now our equation looks like this: [tex]y=3x^2-6x+15x[/tex]. We just need to multiply the last terms, [tex]15[/tex] and [tex]-2[/tex]. This comes out as [tex]-30[/tex].

Our equation at this point has been fully multiplied:

[tex]y=3x^2-6x+15x-30[/tex]

We can see that we still have two like terms, [tex]-6x[/tex] and [tex]15x[/tex]. These can be combined to simply [tex]9x[/tex]. Our final equation, then, is this: [tex]y=3x^2+9x-30[/tex]

Answer:

4%

Step-by-step explanation:

using a calculator, you can do 5200/130000 and get 0.04

:)

Answer:

4%

Step-by-step explanation:

Given:

Present population = 130,000

Future population = 135,200

Find:

Increase in percent

Computation:

Increase in population = Future population - Present population

Increase in population = 135,200 - 130,000

Increase in population = 5,200

Increase in percent = [Increase in population / Present population]100

Increase in percent = [5,200/130,000] 100

Increase in percent = 4%

Answer:

144

Step-by-step explanation:

The shape is a trapezoid.

Add 6 and 112, which is eighteen

divide eighteen by 2, which is 9

Finally, multiply 9 and sixteen which is 144

The solution is, surface area of the given circular cone is 126π units².

Option B is the correct option.

The surface area of a cone is equal to the curved surface area plus the area of the base: π r 2 + π L r , \pi r^2 + \pi L r, πr2+πLr,

where r denotes the radius of the base of the cone, and L denotes the slant height of the cone.

here, we have,

Surface area of a cone is given by the expression,

V = πr(r + l)

Here, r = Radius of the circular base

l = Lateral height of the cone

By substituting the given values in the given expression of volume,

here, given that.

r = 6

l = 15

V = π(6)(6 + 15)

  = 126π units²

Therefore, surface area of the given circular cone is 126π units².

Option B is the correct option.
