Sam took his family to the zoo. An adult's ticket is two times the cost of a child's ticket. The total cost for two adults' tickets and three children's tickets was $28. How much do the tickets cost?

Answers

Answer 1

Answer: Hello,

Let x the cost of a child's ticket
2x is the cost of an adult's ticket

2*(2x)+3x=28
==>4x+3x=28
==>7x=28
==>x=4

2x=2*4=8

Proof:
2 adult's tickets: 2*8=16
3 child's tickets: 3*4=12
and 16+12=28.

Adult's ticket cost is 8
Child's ticket cost is 4

Answer 2

Answer: C=children's ticket. 2c=adult ticket. 2c+2c+c+c+c=$28. Add the c's: 4c+3c=$28. Keep adding/ 7c=$28. Divide by 7: c=$4. A children's ticket is $4 an adult ticket is $8 :)

A fruit bowl contains 2 bananas, 5 oranges, and 4 apples in the simplest form, what is the ratio of apples to bananas in the fruit bowl?

Answers

Answer:

Ratio of apple to banana is 2:1

Step-by-step explanation:

To find ratio of x type of one thing and y type of other thing we divide

x by y and ratio is written as

ratio = x:y

_________________________________

Number of banana = 2

Number of apples = 4

Ratio of apple to banana = Number of apples :Number of banana

Ratio of apple to banana = 4:2

since 4 is divisible by 2 , to get the ratio in simplest form

we divide both numerator and denominator by 2

Ratio of apple to banana = 4/2:2 /2 = 2:1

Thus,

Ratio of apple to banana is 2:1

6.5 ft 6 ft- 11 ft N 5 ft What is the surface area? A 258 square feet B 195 square feet C 228 square feet D 330 square feet

Answers

Answer:

Step-by-step explanation:

area of base = 5×11 = 55 ft²

area of triangle = ½×5×6 = 15 ft²

area of rectangular face = 6.5×11 = 71.5 ft²

surface area = 55 + 2×15 + 2×71.5 = 228 ft²

Can someone help me with these problems? I know the formulas but don't know how to apply it? I'm not that good with word problems. I wrote the answers in a separate sheet just want to compare with someone please!( not to be mean but can S27111855 stop replying your not a big help!)

ok so you know that
V=LWH
basically
volume=height times base area

so
2. V=3 times 8 times 12=288 cm^3

3. triangular prism is 1/2 of the volume of a similar rectangular prism with same measure so
V=1/2 times 4 times 10 times 15=300 cm^3

4. trapezoid base area=area of a trapezoid=(base1+base2)/2 times height so
baseaea=(4+10)/2 times 6=7 times 6=42, then basearea times height=42 times 10=420cm^3

5. cylinder area=base area times height
base=circle=pir^2
r=1/2diameter
6/2=3
base=pi3^2=9pi
area=9pi times 12=108pi cm^3

6. 24pi=4 times pir^2
divide by 4
6pi=pir^2
divd e pi
6=r^2
√6 cm=r

7. square pyramid volume=1/3 volume of similar rectangular prism so
square means base=4 times 4=16
height=9
rectangular volume=16 times 9
pyramid voluume=1/3 times 16 times 9=48 cm^3

8. solve for base side
use pythagorean theorem
slant height=hyposonuse=13
base edge=2 times of 1 of the legs so 10/2=5
so
5^2+x^2=13^2
25+x^2=169
x^2=144
x=12
height of pyramid=12
volume=1/3 times 10 times 10 times 12 times=400 cm^3

2. C
3. B
4. A
5. C
6. B
7. C
8. A

If sqrt x=-7 then x=-49
true or false

Answers

False.

IF √x = -7.

Square both sides

(√x)² = (-7)²

x = (-7)(-7)

x = 49

x will equal 49

False is your answer
