Answer:

80°

Step-by-step explanation:

Angle CBD = 100°

Angle ABC = 180° - 100° = 80°

Angles on a straight line add up to 180°.

Angle ABC and angle EFB are corresponding angles, so they are equal.

= 80°

Answer:

A) x = 80 degrees

B) <CBD = <BFH because of corresponding angles theorem. After that, To find the value of x, We subtract 100(The measure of <BFH) from 180 because x and <BFH were lying on a straight line.

Answer:

[tex]\frac{1}{7}\,\,miles/minute[/tex]

Step-by-step explanation:

Given: Travis and Tony took 40 minutes to skate 5 miles and the return trip took them 30 minutes

To find: average speed for the trip

Solution:

Total distance = 5 + 5 = 10 miles

Total time = 40 + 30 = 70 minutes

So,

Average speed for the trip = Total distance/Total time = [tex]\frac{10}{70}=\frac{1}{7}[/tex] miles/minute

Answer: 5 + 1/4G

Step-by-step explanation:

From the question, Phil starts with G gallons of gas in his tank and Phil used 3/4 of gas. This means:

G - 3/4 = 1/4G

He is left with 1/4G and and then fills the tank with 5 gallons. The expression that represents the amount of gas now in his tank will be:

= 1/4G + 5 or 5 + 1/4G

Answer:

(C)

Step-by-step explanation:

p - q/2 = 3

p - q = 6

rp - rq = 12

r (p - q) = 12

r × 6 = 12

r = 12/6

r = 2

Given:

To find out:

Find the value of r ?

Solution:

p - q / 2 = 3

⇒ p - q = 3 × 2

⇒ p - q = 6

Now,

rp - rq = 12 [ Given ]

⇒ r ( p - q ) = 12

⇒ r ( 6 ) = 12

⇒ r = 12/6

⇒ r = 2

Hence, the value of r is 2.

Answer:

infinite solutions

Step-by-step explanation:

Multiply the second equation by 2

6x + 2y = 10

3x + y = 5

6x+2y = 10

This is identical to the first equation

This means there are infinite solutions

Explanation:

Urgent care centers: care for basic needs after regular doctor hours

Hospitals: treat time-sensitive emergencies

Medical specialists: offer treatment in a specific field of medicine, such as cardiology

General practice doctors and nurse practitioners: care for routine medical needs

Crisis pregnancy centers: provide counseling for unplanned pregnancies

__

Discussion

Urgent care centers are often open all hours, but may not be as fully equipped (or staffed) to provide the sort of emergency medicine that a fully-equipped hospital can provide. While a general- or nurse-practitioner can provide routine care, they will consult with specialists when expertise is needed in a specific area.

Various kinds of pregnancy centers can provide counseling and perhaps some medical services for planned or unplanned pregnancies.

Step-by-step explanation:

Answer:

1  2/3

Step-by-step explanation:

The denominators are the same, so we have to borrow from the 4

Borrow  1 in the form 6/6

3 + 6/6+3/6  - 2 5/6

3 9/6   - 2 5/6

1 4/6

Simplify the fraction by dividing the top and bottom by 2

1  2/3

Step-by-step explanation: To subtract mixed numbers, first subtract the fractions.

Notice here however that we have 3/6 - 5/6

which will give us a negative fraction.

Since this will cause us a lot of trouble, instead,

let's rewrite the first mixed number.

We can do this by thinking of 4 and 3/6 as 3 + 1 and 3/6

or 3 + 9/6 by changing 1 and 3/6 to an improper fraction.

So 4 and 3/6 can be written as 3 and 9/6.

So we have 3 and 9/6 - 2 and 5/6.

Now subtract the fractions.

9/6 - 5/6 is 4/6.

So we have 1 and 4/6 or 1 and 2/3.

As an improper fraction, the answer is 5/3.

Answer:

[tex]4\sqrt{7}[/tex]

Step-by-step explanation:

Its a 45, 45, 90 triangle, which means that the hypotenuse is always the equals sides length by [tex]\sqrt{2}[/tex].

[tex](2\sqrt{14} )*\sqrt{2} = 4\sqrt{7}[/tex]

Answer:

[tex]4\sqrt{7}[/tex]

Step-by-step explanation:

The lines on the two sides of the triangle represent congruency (meaning that they both are worth the same value)

Use pythagorean theorem [tex]a^{2} + b^{2} = c^{2}[/tex]. a and b are both the same value

Square root to find c

The answer is then [tex]\sqrt{112}[/tex]  now we need to simplify it further into radical form

Find the greatest set of numbers that include one perfect square and the other a normal number. These numbers should multiply to be 112

These numbers are 16 and 7

16 is the perfect square number because when you square root it, it is a clean number... 4!

The perfect square root always goes outside the radical and the other number (which is 7 in this case) always goes inside the radical

Dependent variable is the output value and the independent variable is the input value. So for y=5x-3, when you input x=3, the output is y=12.

y is the dependent variable.

x is the independent variable.

Answer:

The answer is 68 degrees.

Step-by-step explanation:

Angles of a triangle add up to 180 degrees. So you have to subtract 75 and 37 from 180. (180 - 75 - 37 = 68)

Answer:

C. 68°

Step-by-step explanation:

The angles in a triangle should all add up to 180°, so...

75°+37°+x°=180°

112°+x°=180°

x°=68°

Step-by-step explanation:

rs= 6x-18 +6

$10 a month fixed plus $0.10 for each message.  

Variable:

m - number of text messages per month

Function:

c(m) - cost per month in dollars of Text-Pay Plan for m messages

Answer: c(m) = 0.10 m + 10

The Frequent text plan costs $20 for 0 messages (that's the fixed cost) and has a slope of (30 - 20)/200 = 1/20 = 0.05 dollars per message.

f(m) = 0.05 m + 20

How many text messages per month make these equal?

c(m) = f(m)

0.10 m + 10 =  0.05 m + 20

0.10 m - 0.05 m = 20 - 10

0.05 m = 10

m =  10/0.05 = 200

Check:

c(200) = .1(200)+10 = 20+10 = 30

f(200) = .05(200) + 20 = 10 + 20 = 30, good

Answer: 200 messages

Answer:

$70

Step-by-step explanation:

To add a tip, we must multiply the cost of the bill by 1.15. This will give us the total amount including the tip.

57.86 x 1.15 = 66.539

Because this is money, and it wants us to round to the nearest ten dollars, the cost would be $70. (66.539 is closer to 70 than it is to 60)

Answer:

  (a)  (a² +3a -1)(a² -3a -1)

Step-by-step explanation:

The constant term of the product of the factors will be equal to the product of their constants. Since you want that product to be +1, the signs of the factor constants must be the same. That eliminates choices (c) and (d).

__

To tell which of choices (a) and (b) is correct, we can compute the squared term in their product. Let's do it in a generic way, with the constant (±1) being represented by "c".

We want the a² term in the product ...

  (a² +3a +c)(a² -3a +c)

That term will be the result of multiplying both sets of first and last terms, and adding the product of the middle terms:

  (a²·c) +(a²·c) -9a² = a²(2c-9)

So, we want the factor (2c-9) to be -11, which means c=-1, not +1.

The correct factorization of the given expression is ...

  (a² +3a -1)(a² -3a -1) . . . . matches choice A

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the equation be represented as A

Now , the value of A is

Now , the number √5 is expressed as

Since the square root of 5 is irrational, there is no pattern to the decimal expansion and it never ends. It also indicates that it cannot be expressed as a fraction with an integer denominator and numerator.

Consequently, it is impossible to calculate the precise value of the square root of 5

Hence , the number √5 is an irrational number

Answer:

It would be between 12 and 13.

Step-by-step explanation:

What we must do is find the square root of 160 and then round to the smallest number and the largest number, in this way we will know what integer that root would be, then we have to:

(160) ^ (1/2) = 12.65

If we round to the smallest number it would be 12 and if we round to the largest number it would be 13.

Which means that it would be between 12 and 13.
