A car can go 35 1/2 miles in 1 1/2 miles gallons. How many gallons does a car need to go 639 miles?

Need work please!!

Answers

Answer 1

Answer: 27 gallons

Step-by-step explanation:

Since the car can go 35½ miles in 1½ miles gallons, we need to first calculate the number of miles that the car can go in 1 gallon. This will be:

= 35½ / 1½

= 71/2 / 3/2

= 71/2 × 2/3

= 23⅔ miles per gallon.

Therefore, the amount of gallons that the car need to go 639 miles will be:

= 639 / 23⅔

= 639 ÷ 71/3

= 639 × 3/71

= 27

The car will need 27 gallons.

sin = opposite/hypothenuse
Given opposite = 16
Hypothenuse = ?
Use Pythagorean theorem to find hypothenuse

12^2 + 16^2 = h^2
144 + 256 = h^2
h^2 = 400, h = 20

You know hypothenuse is 20
Opposite/hypothenuse

Solution: 16/20
Simplify if you need to (4/5)

Answer:

[tex]\boxed {\boxed {\sf sin(\theta)=\frac {16}{20}}}[/tex]

Step-by-step explanation:

We are asked to find the sine for the angle indicated. Remember that sine is equal to the opposite over the hypotenuse.

sin(θ)= opposite/hypotenuse

Analyze the triangle given. We have the 2 legs (16 and 12), but we do not have the hypotenuse (the longest side). We must solve for it.

Since this is a right triangle, we can use the Pythagorean Theorem.

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

Where a and b are the legs and c is the hypotenuse. We know 16 and 12 are the legs.

[tex](16)^2+(12)^2=c^2[/tex]

Solve the exponents.

16²= 16*16=25612²= 12*12= 144

[tex]256+144=c^2[/tex]

[tex]400=c^2[/tex]

Since we are solving for c, we must isolate the variable. It is being squared, so we take the inverse: a square root.

[tex]\sqrt{400}=\sqrt{c^2} \\20=c[/tex]

Now we know the hypotenuse is 20. The side opposite of the angle θ is 16.

opposite= 16 hypotenuse=20

[tex]sin (\theta)= \frac {opposite}{hypotenuse} \\sin (\theta)= \frac{16}{20}[/tex]

The sine of the angle is equal to 16/20. This can be reduced to 4/5 if necessary (by dividing the numerator and denominator by 4).

there will be 8 geese and 12 pigs

the equation would be first to find out how many geese there are

pigs have 4 feet and geese have 2
g=geese p=pigs

4(20-g)+2g=8

now we know there are 8 geese which is 8•2 so 16 feet!

now use what we know to find out how many pigs there are

20-8 is 12 which means 12 pigs or 12•4 which means 48 feet

you can check it by adding the feet and animals

12+8=20 animals
48+16=64 feet!

How to find the arc length (geometry)

Answers

Answer:

94.2

Step-by-step explanation:

Arc length is basically circumference.

Circumference formula: 2πr

All we need is the radius.

Radius = r

15 x 2 = 30 (diameter)

Then we are going to multiply by pi.

Arc length = 30π OR 94.2

[tex]1125 = c^{2}[/tex]

The marked price of a radio is Sh. 12600. If the shopkeeper can allow a discount of 15% on the marked price and still make a profit of 25%.At what price did the shopkeeper buy the radio?​

Answers

Answer:

13388

Step-by-step explanation:

12600 will be 100% so we want to get at what price its sold when there is a 15%dicount

So will minus 15% from the 100% of the Mp

100%-15%=85%

so if 100%=12600

what about 85%=?

we crossmultiply

85%×12600/100%=10710

so10710 is what the radio will be sold if a 15% dicount is given but we want to get wat price the shopkeeper got in that he made a profit of25%

so if 100%=10710

what about 125%

125%×10710/100%=13387.5 which is 13388/=

Raymond has two bags of candy. • Bag A has 15 total pieces of candy, 9 are chocolate candies. Bag B has 10 total pieces of candy, 5 are chocolate candies. Which statement is true?

Answers

Answer:

The probability of selection of chocolate candy from bag A is ( 10%) bigger than from the bag B

Step-by-step explanation:

From bag A the probability (p₁ ) of selection  ( in a random sample) of one chocolate candy is

p₁ = 9/15       p₁  = 0,6

From bag B the probability ( p₂ ) of selection ( in a random sample) of one chocolate candy is:

p₂ = 5/10       p₂ = 0,5

Then the probability of selection of chocolate candy from bag A is bigger than from the bag B

p₁ > p₂      p₁ - p₂  = 0,6 - 0,5       p₁ - p₂ = 0,1    p₁ - p₂ = 10%

A bag contains white, blue and red ping-pong balls in the ratio 8 : 3 : 2. There are 10 balls. If 10 white and 10 blue balls are removed from the bag, the new ratio is ?

Answers

Answer:

the new ratio of white, red and blue balls is 6:2:1

Step-by-step explanation:

The computation of the new ratio is shown below:

If you have 10 red balls, so the blue balls is in proportion of 3:2 that means 15 would be the blue balls. In addition to this, the while balls is in proportion 8:2 = 4:1 so there is a 40 white balls

Now if 10 white and 10 blue balls would be eliminated

So there is 30 white, 10 red, 5 blue bals

Also

30 = 5 × 6

And,

10 = 5 × 2

so the new ratio of white, red and blue balls is 6:2:1
