1000 ft to 1950 ft in 4 miles what is slope
Answers
Answer:
0.05
Step-by-step explanation:
Slope is the vertical drop or rise to the horizontal distance;
Slope = [tex]\frac{vertical interval}{horizontal distance}[/tex]
Let us convert 4 miles to feet;
1 mile = 5280ft
4 miles = 4 x 5280 = 21120ft
Slope = [tex]\frac{1950 - 1000}{21120}[/tex] = 0.05
The slope is 0.05
Write a system of equations to describe the situation below, solve using elimination, and fill in the blanks.
An employee at a construction company is ordering interior doors for some new houses that are being built. There are 2 one-story houses and 4 two-story houses on the west side of the street, which require a total of 64 doors. On the east side, there are 5 one-story houses and 4 two-story houses, which require a total of 88 doors. Assuming that the floor plans for the one-story houses are identical and so are the two-story houses, how many doors does each type of house have?
Each one-story house has
doors, and each two-story house has
doors.
Answers
Answer: This is a system of equations, let's set it up. I set the variable for 1 story houses to x and 2 story houses to y. Here are the two equations:
6x + 2y = 72
5x + 7y = 124.
Now we multiply the equations so that when we add them together one of the variables will be cancelled out. I am going to multiply the top equation by 7 and the bottom equation by -2. This gives us
42x + 14y = 504
-10x -14y = -248
Add the two equations together:
32x = 256
Divide by 32 to get x = 8. The one story houses have 8 doors. We can plug this number into one of the original equations and solve for y now. I'm going to use the first equation.
(6*8) + 2y = 72
Now we solve for y
y = 12 So, the 1 story houses have 8 doors and the 2 story houses have 12 doors.

Answer:
[tex]\frac{1}{5}[/tex]
Step-by-step explanation:
Given the expression;
[tex]\lim_{x \to \infty} \dfrac{x+x^2}{5x^2}[/tex]
To find the limit of the function, we need to first divide through by the highest degree if x i.e x² as shown;
[tex]\lim_{x \to \infty} \dfrac{\frac{x}{x^2} +\frac{x^2}{x2}}{\frac{5x^2}{x^2} }\\ \lim_{x \to \infty} \frac{\frac{1}{x}+ 1 }{5}\\As \ x \ tends \ to \ \infty, \ \frac{1}{x} \ tends \ to \ zero. \ Hence;\\ \lim_{x \to \infty} \frac{\frac{1}{x}+ 1 }{5} = \frac{0+1}{5}\\= \dfrac{1}{5}[/tex]
Hence the limit of the function as x tends to infinity is [tex]\frac{1}{5}[/tex]

the coordinate of vertex X'? *
W (1,6)
Y (3, 2)
z (1,2)
Explain how you determined your answer.
Your answer
Answers
Answer:
X' = (6 , 12)
Step-by-step explanation:
Dilation means to stretch or increase with some factor.
We are given the coordinates of rectangle as
W (1,6), Y (3, 2), Z (1,2)
plot this on the Cartesian plane
Coordinate of X is missing
Since the shape is a rectangle so its mid point diagonal intersection point will remain same.
using this the diagonal is
W (1,6) and Y (3,2) are diagonal points
D = ([tex]\frac{3+1}{2} , \frac{6+2}{2}[/tex]) = (2, 4)
Coordinate of X will be
X( x,y) and Z (1,2)
X = ( [tex]\frac{x+1}{2}, \frac{y+2}{2}[/tex]) = (2,4)
this will give x= 3 and y = 6
X ( 3,6)
Now Dilating by the scale factor of 2
Coordinate of X' = X( 2x, 2y)
X' = ( 2*3, 2*6)
X' = (6 , 12)

In a certain country license plates consist of zero or one digit followed by four or five uppercase letters from the Roman alphabet.
(a) How many different license plates can the country produce?
(b) How many license plates have no repeated letter? (c) How many license plates have at least one repeated letter?
(d) What is the probability that a license plate has a repeated letter? (Round your answer to the nearest whole percent.)
Answers
Answer:
Step-by-step explanation:
From the given information:
The number of different license plate the country can produce is in the form:
=L₁L₂L₃L₄ or L₁L₂L₃L₄L₅ or D₁L₁L₂L₃L₄ or D₁L₁L₂L₃L₄L₅
∴
The Total number of the license plate that can be produced is;
= 26⁴ + 26⁵ + (10 × 26⁴) + (10 × 26⁵)
= 456976 + 11881376 + 4569760 + 118813760
= 135721872
Number of license plate with no repeated letter = P(26,4) + P(26,5) + 10 P(26,4) + 10 P(26,5)
= 11 P(26,4P + 11 P(26,5)
[tex]=11 \times \dfrac{26!}{(26-4)!} + 11 \times \dfrac{26!}{(26-5)!}[/tex]
= 90776400
c) The number of the licensed plate with 1 repeated letter = Total number of the licensed plate - number of the licensed plate with no repeated letter.
= 135721872 - 90776400
= 44945472
d) The probability that a licensed plate has repeated letter is:
[tex]= \dfrac{no(rep \ letter) }{n (total)} \times 100\%[/tex]
[tex]= \dfrac{44945472}{135721872}\times 100\%[/tex]
= 33.12%
A) The country can produce 118,813,760 different licence plates.
B) 78,936,000 license plates have no repeated letter.
C) 39,877,760 license plates have at least one repeated letter.
D) The probability that a license plate has a repeated letter is 33.56%.
Given that in a certain country license plates consist of zero or one digit followed by four or five uppercase letters from the Roman alphabet, to determine (A) how many different license plates can the country produce; (B) how many license plates have no repeated letter; (C) how many license plates have at least one repeated letter; and (D) what is the probability that a license plate has a repeated letter, the following calculations must be performed:
A)
10 x 26 x 26 x 26 x 26 x 26 = X 10 x 11,881,376 = X 118,813,760 = X
B)
10 x 26 x 25 x 24 x 23 x 22 = X 10 x 7,893,600 = X 78,936,000 = X
C)
118,813,760 - 78,936,000 = X 39,877,760 = X
D)
118,813,760 = 100 39,877,760 = X 39,877,760 x 100 / 118,813,760 = X 33.56 = XLearn more about quantities in https://brainly.com/question/12161780

a pump can fill 2400 litres an hour and its replacement model can fill 2.5% more, how man litters an hour can the new model fill
Answers
Answer:
2,460 liters per hour
Step-by-Step Explanation:
The problem above requires only two operations: multiplication and addition. First, you have to answer this question: How much is 2.5% of 2,400 liters?"
You may do this by multiplying 2,400 by 2.5%.
2,400 x 2.5% (0.025) = 60 liters (this is the amount that the new model can fill more than old model).
Then, you have to add 60 liters to 2,400 liters.
2,400 liters + 60 liters = 2,460 liters
This means that the new model can fill 2,460 liters per hour.

The simplest form of the complex fraction [tex]\frac{\frac{8}{9}}{8}[/tex] is [tex]\frac{1}{9}[/tex]
Step-by-step explanation:
In the complex fractions [tex]\frac{\frac{a}{b}}{c}[/tex] = [tex]\frac{a}{b}[/tex] ÷ c
To simplify it change ÷ to × and reciprocal c
[tex]\frac{\frac{a}{b}}{c}[/tex] = [tex]\frac{a}{b}[/tex] ÷ c = [tex]\frac{a}{b}[/tex] × [tex]\frac{1}{c}[/tex] = [tex]\frac{a}{bc}[/tex]In the complex fractions [tex]\frac{a}{\frac{b}{c}}[/tex] = a ÷ [tex]\frac{b}{c}[/tex]
To simplify it change ÷ to × and reciprocal [tex]\frac{b}{c}[/tex]
[tex]\frac{a}{\frac{b}{c}}[/tex] = a ÷ [tex]\frac{b}{c}[/tex] = a × [tex]\frac{c}{b}[/tex] = [tex]\frac{ac}{b}[/tex]Let us solve the question
∵ The complex fraction is [tex]\frac{\frac{8}{9}}{8}[/tex]
∵ [tex]\frac{\frac{8}{9}}{8}[/tex] = [tex]\frac{8}{9}[/tex] ÷ 8
→ Change ÷ to × and reciprocal 8
∴ [tex]\frac{8}{9}[/tex] ÷ 8 = [tex]\frac{8}{9}[/tex] × [tex]\frac{1}{8}[/tex]
→ Cancel 8 up with 8 down
∴ [tex]\frac{8}{9}[/tex] × [tex]\frac{1}{8}[/tex] = [tex]\frac{1}{9}[/tex]
∴ The simplest form of the complex fraction [tex]\frac{\frac{8}{9}}{8}[/tex] is [tex]\frac{1}{9}[/tex]

Step-by-step explanation:
In the fraction 8/9, 8 is the numerator and 9 is the denominator. When you ask "What is 8/9 simplified?", we assume you want to know how to simplify the numerator and denominator to their smallest values, while still keeping the same value of the fraction. We do this by first finding the greatest common factor of 8 and 9, which is 1.

the sum of 4 consecutive even integers is -164. what is the value of the greatest integer
Answers
Answer:
The value of the greatest integer is -38
Step-by-step explanation:
Let's make
x = the first even integer
x + 2, x + 4, x + 6 are the following even integers.
Recall even numbers are counted every other number.
The sum of all the numbers is -164:
x + x + 2 + x + 4 + x + 6 = -164
Simplifying:
4x + 12 = -164
Subtracting 12:
4x = -164 - 12 = -176
Dividing by 4:
x = -176 / 4 = -44
Thus, the greatest of them all is x + 6 = -44 + 6 = -38
The value of the greatest integer is -38
