Answer:

54.6

Step-by-step explanation:

(18⅕ miles)/(⅓ hour) = ((18⅕)×3 miles)/hour = 54.6 miles per hour

The unit rate of the top running speed of a horse in miles per hour is 54.6 miles per hour.

There is an independent quantity, and a quantity that depends on it (dependent quantity). When independent quantity moves by a unit measurement (single unit increment), the increment in dependent quantity is called the rate of increment of dependent quantity per unit increment in independent quantity.

Speed can be calculated as the ratio of the distance traveled to the time taken by the object.

We have been given that horses can run at a top speed of 18⅕  miles in 1/3 hour.

Therefore, Distance = 18⅕ miles

Speed =  18⅕  miles in 1/3 hour.

Thus, we get;

Unit rate= (18⅕ miles) / (⅓ hour)

Unit rate = ((18⅕)×3 miles)/hour

Unit rate = 54.6 miles per hour

Therefore, the unit rate of the top running speed of a horse in miles per hour is 54.6 miles per hour.

Answer:

100 gumdrops per person

Step-by-step explanation:

We know that there are 28 packages and each one has 25.  So just multiply 28 by 25 and you get 700 gumdrops in total.  Finally because there are seven friends in total you divide 700 by 7 and get 100 per person.

A is the answer because its rate of change is 3 while the rest are smaller than that

Yes because the 0 at the end is just a place holder basically so 1.150 and 1.15 are the same

Answer: 2,5

Step-by-step explanation:

In order to find the domain of a function, check the function for two conditions:

a zero in a denominator

a negative under an even root

Exclude the values at which the function satisfies either or both of these conditions from its domain.

G(x) has no root but it does have a denominator. Therefore, check the first condition by setting the denominator equal to zero and excluding those solutions from the domain.

Answer:

The single decimal multiplier is 1.26.

Step-by-step explanation:

Multipliers:

For a decrease of a%, we multiply by: [tex]\frac{100-a}{100}[/tex]

For a increase of a%, we multiply by: [tex]\frac{100+a}{100}[/tex]

For consecutive changes, we multiply the multipliers.

Increase of 5%

Multiply by [tex]\frac{100+5}{100} = \frac{105}{100} = 1.05[/tex]

Increase of 20%

Multiply by [tex]\frac{100+20}{100} = \frac{120}{100} = 1.2[/tex]

Consecutive:

1.05*1.2 = 1.26

The single decimal multiplier is 1.26.

Answer:

Option C is the right answer

The arcs on the Golden Gate Bridge.

I think about the Golden Gate Bridge, which is a suspension bridge.

As in any suspension bridge, a long cable is supported by two large supports.

The cable falls from support, in the form of a curve concave upwards, to a minimum point that is the vertex of the parabola, through which the axis of symmetry passes, and curves again upwards to ascend to the upper end of the other support.

As a unique feature of this parabolic arc, you can tell that the concavity is upward; the parabola opens upward.

Also, you can tell that the parabola is vertical, which means that the axis of symmetry is vertical.

The symmetry is clear because the curve to the left of the vertex is a mirror image of the curve to the right of the vertex. Hope I helped, have a good day!

Answer:

  c = 6√2

  d = 12

Step-by-step explanation:

The sides of any isosceles triangle (opposite the congruent angles) are congruent. Hence c = 6√2.

The hypotenuse of an isosceles right triangle is √2 times the side length, so ...

  d = c√2 = (6√2)(√2) = 6·2

  d = 12

__

If you don't believe that, you can always use the Pythagorean theorem to find d:

  d^2 = (6√2)^2 +c^2

  d^2 = 72 +72 . . . . . . . . . since c=6√2

  d = √144

  d = 12

Answer:

$42.50

Step-by-step explanation:

$42.50 will cover the costs of all people who request full refunds, while still allowing the company to profit.

The average cost the retailer should expect to pay to each customer if It estimates that 60% of customers never make a claim is $4250.

The average is a numeric figure that represents a big amount of data in a single way. The average mark of the class is calculated by averaging the students' grades in a given subject.

It is more important to understand how the class as a whole performed than how each individual student performed.

Given:

It estimates that 60% of customers never make a claim, 25% require a small repair costing an average of $50 and 15% require a full refund costing $200,

Calculate the average cost as shown below,

Assume there are 100 customers, then,

The average cost = 25% of 100 × 50 + 15% of 100 × 200

The average cost = 25 × 50 + 15 × 200

The average cost = 1250 + 3000

The average cost = 4250

Thus, the average cost the retailer should expect to pay to each customer is $4250.

Answer:  398765

=====================================================

Work Shown:

x = total number of copies sold so far

8.1% of x = 0.081*x = amount of copies sold in the first month

0.081*x = 32300

x = 32300/0.081

x = 398,765.432098766

x = 398,765

Rounding to the nearest whole number, about 398,765 copies have been sold so far to date.

Answer:

3 photo frames

Step-by-step explanation:

1 frame uses 1/4 meters. You can solve this as a proportion. 1 is to 1/4 and x is to 3/4. 1/4 x 3 is 3/4. So multiply 3 x 1 as well. You get 3.
