Jim drove 175 miles in 3 hours 30 minutes.
How many miles per hour did Jim drive?

Answers

Answer:

50 miles per hour

Step-by-step explanation:

50 x 3 = 150

50 x 0.50 = 25

150 + 25 = 175

Hope this helps!

The number of miles that Jim can drive in each hour will be 50 miles.

What is speed?

Speed is defined as the length traveled by a particle or entity in an hour. It is a scale parameter. It is the ratio of length to duration.

We know that the speed formula

Speed = Distance/Time

Jim drove 175 miles in 3 hours and 30 minutes. Convert the time into hours, then we have

Time = 3 + 30 / 60

Time = 3.5 hours

The number of miles that Jim can drive is calculated as,

⇒ 175 / 3.5

⇒ 50 miles per hour

write and equation of a parabola with the vertex of (0,3) and the focus of (-8,3)

Answers

Answer:

(y-3)²= -32x

Step-by-step explanation:

1) the required equation has a form: (y-y₀)²=-2p(x-x₀), where (x₀;y₀) - vertex (0;3), p - parameter of the given parabola;

x₀=0; y₀=3.

2) according to the conditiion F(-8;3)=F(x₀+p/2; y₀), it means (x₀+p/2; y₀)=(p/2;3), then p/2= -8; ⇒ p= -16.

3) finally, p= -16; x₀=0; y₀=3, then it is possible to make up the required equation:

(y-3)²= -32x.

PS/ if it is possible check the suggested solution in other sources.

The perimeter of the rectangle below is 56 units. Find the length of side BC.
Write your answer without variables.
DC = 3x - 2 DA = 2x
BC = ?

Answers

Answer:

12 units

Step-by-step explanation:

Perimeter formula:

P = 2(l + w)

Given:

l = 3x - 2w = 2xP = 56

Find the value of x:

2(3x - 2 + 2x) = 565x - 2 = 285x = 30x = 6

BC is parallel side to AD and is:

BC = AD = 2*6 = 12

BC must parallel to DA hence equal

Now

2(Length+Breadth)=Perimeter2(3x-2+2x)=56(5x-2)=285x=30x=6

BC=2(6)=12units

Ali bought 2kg of potato and 3kg of onion. The price of the onion is 50 cents less
than potato. He paid $10 to the cashier and get back $1.50. What is the price for 1kg
of onion ?

Answers

Answer:

1kg of onion is $1.5

Step-by-step explanation:

He paid $10 and got $1.50 back, meaning that the total price for the 2kg and 3kg of the potato and onion is:

10 - 1.5 = $8.50

Now, equating the prices of the two (take x as the cost of the potato per kg and take y as the cost of the onion per kg):

x -0.5 = y

x - y = 0.5  ---- Eq 1

Equating the total costs:

2x + 3y = 8.5 ---- Eq 2

Multiplying Eq 1 by 2:

2x - 2y = 1 ---- Eq 1'

Subtracting Eq 2 from Eq 1':

2x - 2x +3y - (-2y) = 8.5 - 1

5y = 7.5

y = 1.5

Substituting this into the first equation:

x - 1.5 = 0.5

x = 2

Hence,

the cost of the Potato is $2, and

the cost of the Onion per kg is $1.5

Hope this helps, and have a wonderful time ahead on Brainly!

An ice cream factory makes 170 quarts of ice cream in 5 hours. How many
quarts could be made in 36 hours? What was that rate per day?

Answers

The amount of quarts which will be made in 36 hours and the production rate per day is :

1224 quarts on 36 hours 816 quarts in a day

Given the Parameters :

Time taken to make 170 quarts = 36 hours

Number of quarts made in 36 hours using the proportional relationship :

170 = 5

p = 36

Cross multiply :

5p = 170 × 36

5p = 6120

p = 6120 / 5

p = 1224 quarts

The production rate per day :

Number of hours in a day = 24 hours

170 = 5

p = 24

Cross multiply

5p = 170 × 24

5p = 4080

p = 4080/5

p = 816

Therefore, the production rate per day is 816 quarts

What can you divide a2b5 by to get a quotient of 1?

Answers

9514 1404 393

Answer:

  a^2b^5

Step-by-step explanation:

Anything divided by itself is 1.

That is, anything multiplied by its reciprocal is 1. This value (the reciprocal of the expression) is called the "multiplicative inverse." Its value is that the product of an expression and its multiplicative inverse is 1, the multiplicative identity element. (Anything times 1 is itself.)

So, to get 1 as a product, multiply by 1/(a^2b^5), which is to say, divide by a^2b^5 to get 1 as a quotient.
