remember, when 2 signs collide (like a mathematical operation and the sign of an operand of that operation), the following is always true (for additions/subtractions and multiplications/divisions) :

+ + = +

+ - = -

- + = -

- - = +

and don't forget : when a number or term is positive, we usually don't write the sign. only the mathematical operation.

T-Mobile charges a base fee of $15 per month plus $0.05 for each minute. 300 minutes long would you need to call for them to charge the same amount.

Given that,

T-Mobile charges a base fee of $15 per month plus $0.05 for each minute you are on the phone for any long-distance call, while Verizon has a basic rate of only $10 per month but charges $0.10 for long-distance calls.

We have to find how long would you need to call for them to charge the same amount.

We can write the equation as

15+0.05x=0.10x

0.05x-0.10x=-15

-0.05x=-15

0.05x=15

x=15/0.05

x=300 minutes

Therefore, 300 minutes long would you need to call for them to charge the same amount.

Step-by-step explanation:

The order of the scale from smallest to the largest is:

The smallest = 1 inch to 3 yards

The middle : 1 inch to 1.1 yards

The largest : 1 inch to 1 yard

A scale drawing is either a larger or smaller version of a diagram.  A scale factor provides information on the unit of conversion between the original image and the scale drawing.   A scale factor is the ratio of the length of the scale drawing to the length of the actual drawing.

The first step is to convert the given scale factors to the same units of measurement.

All of the measurements would be converted to yards

1 feet = 3 yards

1 inch to 3 yards

1.1 yards = 1 meter

1 inch to 1.1 yards

1 inch to 1 yard

The smallest = 1 inch to 3 yards

The next : 1 inch to 1.1 yards

The largest : 1 inch to 1 yard

Answer: 72 degrees

Step-by-step explanation: We know that angle DHG and angle EHF are congruent due to the vertical angles theorem. Since these two angle measures are congruent, this also means that the expression 6(x-2) is congruent to 3x+30. To find the angle measure of DHG, we need to find x. We can set these two expressions equal to each other and solve for x.

6(x-2) = 3x+30

6x-12 = 3x + 30

-3x -3x

3x-12=30

+12 +12

3x=42

~divide by 3 on both sides~

x = 14

Now that we know our x variable, we can substitute 14 into the expression for angle DHG.

6(14-2)

6(12)

72.

Answer:

∠DHG = 72°

Step-by-step explanation:

As ∠DHG and ∠EHF are vertical angles, they are congruent.

What are vertical angles?

Vertical angles are formed when two lines intersect, creating opposite angles. Those opposites are congruent (equal).

Equation:

∠DHG = ∠EHF

[6(x - 2)] = (3x + 30)

Step 1: Distribute 6 through the parentheses.

[tex]\implies 6(x) + 6(-2) = 3x + 30[/tex]

[tex]\implies 6x - 12 = 3x + 30[/tex]

Step 2: Subtract 3x from both sides.

[tex]\implies 6x - 3x - 12 = 30[/tex]

[tex]\implies 3x - 12 = 30[/tex]

Step 3: Add 12 to both sides.

[tex]\implies 3x - 12 + 12 = 30 + 12[/tex]

[tex]\implies 3x = 42[/tex]

Step 4: Divide both sides by 3.

[tex]\implies \dfrac{3x}{3} = \dfrac{42}{3}[/tex]

[tex]\implies \boxed{x = 14}[/tex]

Step 5: Substitute the value of x into ∠DHG to find its measure.

[tex]\implies \angle DHG = 6(14 - 2)[/tex]

[tex]\implies \angle DHG = 6(12)[/tex]

[tex]\implies \angle DHG = \boxed{72^\circ}[/tex]

Therefore, the measure of ∠DHG is 72°.

The probability that you win a prize is 0.00003797372

From the question, we have the following parameters:

Sample Space = 1 to 22

This means that

Sample size, n = 22 i.e. the count of numbers from 1 to 22

The count of numbers to be drawn is 5

So, the individual probabilities are

P(1) = 5/22

P(2) = 4/21

P(3) = 3/20

P(4) = 2/19

P(5) = 1/18

The probability of winning is the product of the above

So, we have

p = 5/22 * 4/21 * 3/20 * 2/19 * 1/18

Evaluate

p = 0.00003797372

Hence, the probability is 0.00003797372

a. The rate of change in length of baby grace is 0.75.

b. The linear equation for Baby Grace growth rate in point slope form is y - 20 = 0.75(x - 4)

a. The slope of the line for baby Claire growth is 0.8.

b. Baby girl Claire growth rate is faster than baby girl Grace growth rate.

Let's solve for the growth chart of baby grace.

Therefore,

a.

The rate of change in length of baby Grace can be found as follows:

rate of change = y₂ - y₁ / x₂ - x₁

Hence, using (4, 20)(6, 21.5)

rate of change = 21.5 - 20 / 6 - 4

rate of change = 1.5 / 2

rate of change = 0.75

b . The linear equation in point slope form can be found as follows;

y - y₁ = m (x - x₁)

where

Therefore,

y - 20 = 0.75(x - 4)

Let's tackle the growth chart for baby Claire,

a.

slope of the line = y₂ - y₁ / x₂ - x₁

Using (4, 22)(14, 30)

slope of the line = 30 - 22 / 14 - 4

slope of the line = 8 / 10

slope of the line = 4 / 5 = 0.8

b.

Therefore, Baby Claire growth rate is faster than baby Grace.

This is because bay Claire growth rate is 0.8 and baby Grace is 0.75.

From the equation 3x + 59 = 120, the unit cost of the shirts is $20.33.

An equation is a mathematical statement used to equate two mathematical expressions.

To demonstrate equality, equations use the equation symbol (=).

The total amount spent on new clothes = $120

The number of shirts bought = 3

The cost of the pair of pants bought = $59

Equation of the situation is 3x + 59 = 120,where x = the unit cost of the shirts.

3x + 59 = 120

Subtract 59 from both sides:

= 3x + 59 - 59 = 120 - 59

Simplify both equations:

3x = 61

Divide both sides by 3:

3x/3 = 61/3

x = 20.33

Thus, we can conclude that the equation for the new clothes Jennifer bought at the mall shows that each shirt costs $20.33.

Corresponding parts of congruent triangles are congruent.

What do you mean by congruency?

In geometry, two figures or objects are said to be congruent if their shapes and sizes match, or if one is the mirror image of the other. Formally speaking, two sets of points are said to be congruent if—and only if—they can be changed into one another by an isometry, which is a combination of rigid movements like translation, rotation, and reflection. This indicates that one item may be exactly aligned with the other object by moving and reflecting it, but not by resizing it. So if we can cut out and then perfectly match up two separate plane figures on a sheet of paper, they are congruent. The paper may be turned over.

The value of the function n(x) = -1 -x + 4 when x = -2,0, and 5 are  respectively.

Function:

A function is defined as a relationship between a set of inputs having one output each.

It can be represented as f(x).

Given,

Here we have the function

n(x) = -1 -x + 4

And we need to find the value of the function when x takes the values -2, 0 and 5.

To solve this one, then we have to put the value of x on the function and then we have to simplify it in order to get the value of the function.

For that first we have to put the value of x = -2, then we get,

n(-2) = -1 - (-2) + 4

n(-2) = -1 + 2 + 4

n(-2) = -1 +6

n(-2) = 5

Now we have to apply the value of x as 0, then we get the value of function as,

n(0) = -1 - 0 + 4

n(0) = -1 + 4

n(0) = 3

Finally we gave to apply the value of x as 5, then we get the value of n(5) as,

n(5) = -1 - 5 + 4

n(5) = -6 + 4

n(5) = -2
