Answer:
$68.24
Step-by-step explanation:
Three friends went to Texas Roadhouse for dinner. The total bill was $76.25. They left the server a 20% tip and the Montgomery County tax rate is 9.5%.
Given data
The total bill was $76.25
tip
=20/100*76.25
=0.2*76.25
=15.25
Tax
=9.5/100*76.25
= 0.095*76.25
=$7.24375
In all the bills is 76.25-15.25+7.24375
=61+7.24375
=$68.24

Answer:
2) (see image below)
3) x = 8
side(s) = 74
4) x = 10
EF = DE = 67
base = 31
Step-by-step explanation:
For No. 2, if you draw out two triangles with the corresponding angles, you can make it a lot easier. See the image below:
For No. 3, it is given that it's an equilateral triangle, meaning all sides and angles are congruent. So:
12x – 22 = 10x – 6 = 7x + 18
Instead of using all three at once, you can use any two. I'll be using:
12x – 22 = 10x – 6
2x = 16
x = 8
Plugging x in, we can get all the sides, because this is an equilateral triangle:
12x – 22
12(8) – 22
96 – 22
74
For No. 4, it is given that the triangle is an isosceles triangle where DE ≅ EF, so:
8x – 13 = 5x + 17
3x = 30
x = 10
Plugging in x for one of the congruent sides and the base, you can get your needed side length values:
8x – 13
8(10) – 13
80 – 13
67
x + 21
10 + 21
31
Find p(-3) if p(x)= 4x^3 - 5x^2 + 7x - 10.

= 4(-27) - 5(9) - 21 - 10
= -108 - 45 - 21 - 10

constant monomial
sixth-degree monomial
linear binomial
sixth-degree binomial
Answer:
constant monomial
Step-by-step explanation:
The polynomial, 9, has 1 term and its degree is 0. Therefore, the polynomial is a constant monomial.
The given expression is a constant monomial. Therefore, option A is the correct answer.
What is the polynomial?A polynomial is a type of algebraic expression in which the exponents of all variables should be a whole number. The exponents of the variables in any polynomial have to be a non-negative integer. A polynomial comprises constants and variables, but we cannot perform division operations by a variable in polynomials.
Here given expression is 9.
A constant monomial is a term with only a constant number. There is no variable in a constant monomial.
So, 9 is a constant monomial.
The given expression is a constant monomial. Therefore, option A is the correct answer.

Find the number that makes the ratio equivalent to 2:9. 6:
The perimeter of a rectangular field that measures 2 feet by 18 inches is _________ ft.
Answer:
7 ft
Step-by-step explanation:
As we know that the formula to find the perimeter of a rectangle is
P = 2 (l) + 2(w). With that being said, we can look at the question.
The answer should be given in terms of feet, so we will have to convert 18 inches to ft. In order to convert from inches to ft, you will have to divide by 12.
18 / 12 = 1.5ft
18 inches = 1.5 foot
Now we take the given values and put them into the formula to find the perimeter of the rectangular field.
2 (l) + 2(w) = 2 (2 ) + 2 (1.5) = 7ft
The perimeter of the rectangular field is 7ft.

z=20°
Answer:
X= 70
Z= 20
y= 30°
Step-by-step explanation:
Finding X:
Sum of angle in a straight line is 180
Therefore X = 180-110
Finding z:
Sum of angle in triangle is 180, and it’s a right angled triangle (90°)
Z= 180-(x+90)
Z= 180-( 70+90)
Finding y, look at the big triangle ABC:
There’s a right angle and <C is 40°,
Therefore <B is 180-(40+90)= 50°
<B= y + z
50° = 20° + y
y= 30°

A certain city has a population of about 100,000. There are 3,101 people with red hair in the city. Which of these is closest to the probability that a randomly selected person in the city has red hair?
Answer:
3%
hope this helps!
Step-by-step explanation:
The closest probability of a randomly selected person in the city having red hair is approximately 0.03 (or 3%).
What is probability?Probability is defined as the possibility of an event being equal to the ratio of the number of favorable outcomes and the total number of outcomes.
A certain city has a population of around 100,000 people. In the city, there are 3,101 people with red hair.
The required probability can be calculated by dividing the number of people with red hair by the total population of the city:
= 3,101 / 100,000
= 0.03101,
It can be rounded to 0.03.
Thus, the required probability is 0.03.

B. 1260 m/s
C. 97.22 m/s
Answer:
350 kilómetros por hora son 97,2222 metros por segundo ;)
The result of converting 350 km/h to meter per second is 97.22 m/s.
To convert from kilometers per hour (km/h) to meters per second (m/s), you need to apply the conversion factor.
The conversion factor for this conversion is 1 km/h = 0.2778 m/s.
To convert 350 km/h to m/s, multiply 350 by the conversion factor:
350 km/h×0.2778 m/s
= 97.22 m/s
Therefore, the result of converting 350 km/h to m/s is approximately 97.22 m/s.

Rearrange t= 5s + 4 to make s the subject
Answer:
Subject 's' in terms of 't'
[tex]s = \frac{t-4}{5}[/tex]
Step-by-step explanation:
Explanation:-
Given that the subject 't in terms are 's'
Given that t = 5 s +4
subtracting '4' on both sides, we get
t - 4 = 5s +4-4
t - 4 = 5 s
Dividing '5' on both sides ,we get
[tex]\frac{t-4}{5} = \frac{5s}{5}[/tex]
[tex]\frac{5s}{5 } = \frac{t-4}{5}[/tex]
[tex]s = \frac{t-4}{5}[/tex]

Part A
Drag numbers to complete an equation for the trend line. Numbers may be used once, more than once, or not at all.

y = ?x + ?
Part B
Using the linear equation, predict the average height for a two-year old.
A. 15 inches
B. 22 inches
C. 31 inches
D. 35 inches
Answer:
(a) [tex]y = 4.5x + 22[/tex] -- The equation
(b) 31 inches
Step-by-step explanation:
Given
See attachment
Solving (a): The equation of the trend line.
We start by calculating the slope (m)
[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
Where
[tex](x_1,y_1) = (0,22)[/tex]
[tex](x_2,y_2) = (4,40)[/tex]
So, we have:
[tex]m = \frac{40 - 22}{4 - 0}[/tex]
[tex]m = \frac{18}{4}[/tex]
[tex]m = 4.5[/tex]
The equation is then calculated using:
[tex]y = m(x-x_1)+y_1[/tex]
Where:
[tex](x_1,y_1) = (0,22)[/tex]
[tex]m = 4.5[/tex]
[tex]y = 4.5(x - 0) + 22[/tex]
Open bracket
[tex]y = 4.5x - 0 + 22[/tex]
[tex]y = 4.5x + 22[/tex]
(b) The height of a 2 year old.
To do this, we substitute 2 for x in [tex]y = 4.5x + 22[/tex]
[tex]y = 4.5 * 2 + 22[/tex]
[tex]y = 9+ 22[/tex]
[tex]y = 31[/tex]
The prediction is 31 inches
An international company has 23,200 employees in one country. If this represents 26.7% of the company's employees, how many employees does it have in total?
Round your answer to the nearest whole number.
Answer:
Total number of employees = 86,891 employees
Step-by-step explanation:
Let
x = total number of employees
26.7% of x = 23,200
26.7/100 * x = 23,200
0.267 * x = 23,200
0.267x = 23,200
x = 23,200/0.267
x = 86,891.385767790
approximately 86,891 employees
Total number of employees = 86,891 employees
