Mr and mrs smith buy tickets for themselves and their four children. the cost of an adult ticket is ? 6 more than the adult tick

kirill115 [55]

Answer:

child's ticket = 4.75 adult ticket=10.75.

Step-by-step explanation:

The cost of an adult ticket is 6 more than that of a child ticket, so will be denoted by c+6. Now, we are told that the cost of four child tickets and two adult tickets is 40.50, so we can put this in an equation and solve for c:

(c+6)+(c+6)+c+c+c+c=40.50

6c+12=40.50

6c=28.50

c=4.75

Therefore the cost of a child's ticket (c) is 4.75 and the cost of an adult ticket (c+6) is 10.75.

15. A cylindrical glass 10 cm tall and 8 cm in diameter is filled to 1 cm

ANTONII [103]

Answer:

No. The new height of the water is less than the height of the glass(6.33 cm<10 cm)

Step-by-step explanation:

-For the water in the glass to overflow, the volume of the inserted solid must be greater than the volume of the empty space or the ensuing height of water >height of glass.

#Volume of the golf ball:

$V=\frac{4}{3}\pi r^3\\\\=\frac{4}{3}\pi \times 4^3\\\\\approx 268.08\ cm^3$

#The volume of the water in the glass:

$V=\pi r^2 h\\\\=\pi \times 4^2\times 10\\\\\approx 50.27\ cm^2$

We then equate the two volumes to the glass' volume to determine the new height of the water:

$V=\pi r^2h\\\\(206.08+50.27)=\pi r^2 h\\\\h=318.35/(\pi \times 4^2)\\\\=6.33\ cm$

Hence, the glass will not overflow since the new height of the water is less than the height of the glass(6.33 cm<10cm).

10+25+15=50

25/50

I can be simplified.

The greatest common factor is 25.

25/25=1

50/25=2

So the answer is 1/2.

The surface area of the triangular prism is calculated as: 153 cm²

<h3>How to Find the Surface Area of a Triangular Prism?</h3>

The net of a triangular consists of 2 identical triangular faces, and three different rectangular faces. Given the net of a triangular prism, to find the surface area, find the area of each given shape that makes up the net of the triangular prism.

Surface area of the triangular prism = 2(area of triangular base) + area of the 3 different rectangular faces.

Area of triangle = 1/2(b)(h)

Base (b) = 6 cm

Height (h) = 3 cm

Area of the 2 triangular faces = 2[1/2(6)(3)]

Area of the 2 triangular faces = 18 cm²

Area of the larger rectangular face:

Area = (length)(width) = (9)(6)

Area of larger rectangular face = 54 cm²

Area of the medium-sized rectangular face:

Area = (length)(width) = (9)(5)

Area of medium-sized rectangular face = 45 cm²

Area of the smaller rectangular face:

Area = (length)(width) = (9)(4)

Area of smaller rectangular face = 36 cm²

Surface area of the triangular prism = 18 + 54 + 45 + 36

Surface area of the triangular prism = 153 cm²
