Answer: 120 miles

Step-by-step explanation:

      We will set up a proportion to solve.

 Set up a proportion:

[tex]\displaystyle \frac{5\text{ inches}}{10\text{ miles}} =\frac{60\text{ inches}}{x\text{ miles}}[/tex]

 Cross-multiply:

5 * x = 60 * 10

 Multiply:

5x = 600

 Divide both sides by 5:

x = 120 miles

Answer: hi! for the denominators (5, 9, 7) the least common multiple

Step-by-step explanation:

(LCM) is 315.

LCM(5, 9, 7)

Therefore, the least common denominator (LCD) is 315.

Calculations to rewrite the original inputs as equivalent fractions with the LCD:

3/5 = 3/5 × 63/63 = 189/315

4/9 = 4/9 × 35/35 = 140/315

6/7 = 6/7 × 45/45 = 270/315

Classify the number -25.

Natural, Whole, Integer, Rational, Irrational.

25 is a rational number. This number is a whole that may be expressed as the fraction 25/1.

This wouldn't be a natural number because -25 is a negative number.

Since -25 isn't a positive number, this wouldn't be a whole number.

the whole number 85 is -85, which is a negative number. -85 is consequently an integer. Negative numbers are rational numbers.

square integers are frequently irrational, -25 is a square root.

Three variable p, q and r that is true when at most one of the three variables is true.

How do you identify a proposition?

Atmost means maximum.

We have three variables: p,q and r. Maximum one of the three variable is true. However we dont know which variable is true.

Case 1: No variable is true :  ¬p ∧¬q∧¬r

Case 2 : p variable is true:  p ∧¬q∧¬r

Case 3: q variable is true : ¬p ∧q∧¬r

Case 4 : r variable is true : ¬p ∧¬q∧r

One of the 4 cases has to be true . Thus Case1 or Case 2 or Case3 or Case 4 is true. So we need to take comjuction of the propsitions in each case.

The value of r is 11°

From the information given, we have that;

Both angles are complementary angles.

It is important to note that complementary angles sum up to 90 degrees

Then, we have;

52 ° + 4r - 6° = 90°

collect like terms

4r + 46° = 90 °

4r = 90 - 46

4r = 44

Make 'r' the subject of formula

Divide both sides by 4

4r/4 = 44/4

r = 11°

Perhaps: E -45

Step-by-step explanation:

(2x + 4) = 14

2x + 4 = 14

2x = 10

x = 5

This equation has only 1 solution.

There cannot be the product of the "solutions" when there is only 1 solution.

Perhaps you meant this (absolute value, not parentheses):

What is the product of the solutions to the equation?

|2x +4| = 14

A 45

B 81

C 0

D -81

E -45

|2x + 4| = 14

2x + 4 = 14 or 2x + 4 = -14

2x = 10  or  2x = -18

x = 5 or x = -9

The product of 5 and -9 = -45

The solid that results from increasing the number of sides infinitely is; Close to a Cone

We want to describe the solid that results if the number of sides of each base increases infinitely. The bases of each solid are regular polygons inscribed in a circle.

Now, given a pyramid, when its base is a regular polygon whose number of sides increases infinitely, the base gets closer and closer to the shape of a circle, and therefore the solid will be close to a cone.

The statement describing the graph of h(x) is "The graph of h(x) is a vertical translation of the graph of g(x) down 3 units".

In the question, are given two graphs g(x) = - (1/2)x + 6, and h(x) = g(x) - 3.

We are asked for the statement that best describes h(x).

Now, h(x) = g(x) - 3, can be seen as  the translation of g(x).

For any graph m(x), n(x) is its translation if n(x) = m(x + p) + q.

The translation is vertical is q ≠ 0, and horizontal when p ≠ 0. Also,

For, h(x) = g(x) - 3, when we compare it with n(x) = m(x + p) + q, we have p = 0, and q = -3.

Since, q ≠ 0, we have vertical translation, and since q < 0, the translation is |q| units down.

Thus, The statement describing the graph of h(x) is "The graph of h(x) is a vertical translation of the graph of g(x) down 3 units".

300 teenagers went to the zoo.

given that

Tickets to the zoo cost $4 for children.

Tickets to the zoo cost $5 for teenagers.

Tickets to the zoo cost $6 for adults.

1200 people come to the zoo every day.

on a certian day, the total revenue at the zoo was $5300.

Let the number of adults be x.

The number of teenagers be y.

and the number of children that went to the zoo 8y/3.

Consider the question

1200 people come to the zoo every day.

x + y + 8y/3 = 1200

now, take L.C.M between y and 8y/3

[tex]x + \frac{(3y + 8y)}{3} = 1200 \\ x + \frac{11y}{3} = 1200[/tex]

now multiply with 3 to this equation.

3x + 11y = 3600 .......................(1)

tickets to the zoo cost $4 for children, $5 for teenagers and $6 for adults.

according to the question

6x + 5y + 32y/3 = 5300

Now take the L.C.M between 5y and 32y/3

6x + 47y/3 = 5300

now multiply with 3 to this equation.

18x + 47y = 15900 ...................(2)

now, multiply equation (1) with 6

18x + 66y = 21600 .....................(3)

now, subtract equation (1) in equation (2)

(18x - 18x) + (66y - 47y) = (21600 - 15900)

19y = 5700

y = 5700/19

y = 300

Step-by-step explanation:

$2 is the price per cookie so 2c is per every cookie, you multiply by 2 to get the price.

Ana only has $20 so the amount of money she spends has to be less then 20 so the inequality would be 2c < 20

Answer:

This is because the sign < tell us that b is going to be less 6, and the line _ tells us that the solution can also be equal to 6.

The construction of two congruent angles using a scale and compass can be done by applying the prerequisite knowledge of construction.

What is an angle?

A geometrical figure formed by using two rays, which are known as the sides of angle. These sides share a common vertex. Angle can be of various types including acute, obtuse, reflex,  right, etc.

Explanation of constructing an angle using a scale and compass that is both congruent

Start drawing a line with the scale

Then, using this line or edge of the given angle to construct another corner, with the same vertex, let's call it O

Mark an arc across the sides of the corner using compass

Name the points as A and B, where the arc intersects and extend that arc beyond B

Open the compass to length of AB by setting it to the point B, and then mark an arc that intersects the first arc at point C.

Forthwith, wwe have two congruent components, AB = BC.

As the distance is OA = OB = OC, therefore, ∠AOB and ∠BOC are congruent.

Hence, this is the way of constructing congruent angles using a scale and a compass.
