miguel walked 3/4 miles to the library and then 3/8 miles to the post office. Which statement is true?
Answer:
Post office is true because 3/4 miles is 1320 yards and 3/8 is only 660 yards. So basically it will take A LONG TIME for him to get there at the library. But you know I am not always accurate /:
-(4k^2-13k-12)+5k^2-8k How would I be able to write this in standard form with the greatest exponent being first.
Answer:
Step-by-step explanation:
Negative sign is outside the parenthesis. So, each term of (4k² - 13k -12) should be multiplied by (-1)
-(4k² - 13k -12) + 5k² - 8k = 4k²*(-1) - 13k*(-1) - 12*(-1) + 5k² - 8k
= -4k² + 13k + 12 +5k² - 8k
Combine like terms,
= -4k² + 5k² + 13k - 8k + 12
= k² + 5k + 12
Like terms are the terms with same variable with same exponent.
(-4k² ) and 5k² are like terms
13k and (-8k) are like terms

in a class, the ratio of boys to girls is 8 to 5. if there are 75 girls in the class, how many boys are there in the class? process pls
Answer:
120
Step-by-step explanation:
boys : girls
8 : 5
x : 75
to find x, take 75 and divide it by 5:
75 ÷ 5 = 15
(you do this to determine how you can go from 5 to 75)
take the qoutient and multiply it by 8:
15 × 8 = 180

New York City is located about 40˚ north of the equator. If Earth's radius is about 4000 miles, approximately how many miles south would a plane need to fly from new York City to reach the equator?
Answer:
The answer is "2793 miles"
Step-by-step explanation:
In this firstly we convert degrees to radians, which can be defined as follows:
[tex]\to \theta =\frac{40^{\circ} \times \pi }{180^{\circ}}[/tex]
[tex]=\frac{ 2\pi }{9}[/tex]
Now calculating the distance:
[tex]=\frac{2\pi }{9} \times 4000\\\\= \frac{8000 \pi }{9}[/tex]
[tex]=\frac{8000\times 3.14 }{9}\\\\ = \frac{25120}{9}\\\\=2793 \ miles[/tex]

7a.C
7b.Angle AED
7c.Angle 8
7d. Angle 6 and 8
Step-by-step explanation:
6a. The labeled angles are vertical angles so we set them equal to each other.
[tex]7x - 8 = 6x + 11[/tex]
[tex]7x = 6x + 19[/tex]
[tex]x = 19[/tex]
7a.Angle 11 is near Point C so Point C is the vertex.
7b. Angle 5 vertex is E so we can use any 3 points as an angle as long as E is in the middle example, and the angles are on the left side so we can use
[tex]aed[/tex]
Write the angle sign as well.
7c. Angle 6 is vertical from Angle 8.
7d. Angle 7 and 6 form a linear pair and since Angle 6=Angle 8, Angle 7 and 8 form a linear pair as well.
10. The perimeter of a regular nonagon is 162 inches. The apothem is 97.8 inches. Find the area.
Answer:
The area of the regular nonagon is 7921.8 square inches.
Step-by-step explanation:
Geometrically speaking, the area of a regular polygon is determined by following area formula:
[tex]A = \frac{p\cdot a}{2}[/tex] (1)
Where:
[tex]A[/tex] - Area of the regular polygon, in square inches.
[tex]p[/tex] - Perimeter, in inches.
[tex]a[/tex] - Apothem, in inches.
If we know that [tex]p = 162\,in[/tex] and [tex]a = 97.8\,in[/tex], then the area of the regular nonagon is:
[tex]A = 7921.8\,in^{2}[/tex]
The area of the regular nonagon is 7921.8 square inches.

3.1 Factorise completely
3.1.2 3x2 - 2x - 8
Answer:
3x² – 2x – 8
=> 3x² – 6x + 4x – 8
=> 3x( x – 2 ) + 4( x – 2 )
=> ( 3x + 4 ) ( x – 2 )
Therefore,
Either, 3x + 4 = 0
3x = - 4
x = - 4/3 (Ans)
And,
x – 2 = 0
x = 2 (Ans)
Answer:
(x - 2)(3x + 4)
Step-by-step explanation:
Given
3x² - 2x - 8
Consider the factors of the product of the coefficient of the x² term and the constant term which sum to give the coefficient of the x- term.
product = 3 × - 8 = - 24 and sum = - 2
The factors are - 6 and + 4
Use these factors to split the x- term
3x² - 6x + 4x - 8 ( factor the first/second and third/fourth terms )
= 3x(x - 2) + 4(x - 2) ← factor out (x - 2) from each term
= (x - 2)(3x + 4)

c = [tex]\sqrt{41}[/tex] ← exact solution → C
Points A and B have opposite x-coordinates but the same y-coordinates. On a coordinate plane, point A is 2 units to the left and 3 units up. Point B is 2 units to the right and 3 units up. How many units away are each of the points from the y-axis? 2 3 4 5
Answer: 5
Step-by-step explanation: If you take minus 2 and take it to 0 then add 3 you get 5
The points A and B are 2 units away from the y-axis.
What is Cartesian coordinates system?"It is used to specify the location of a point in two-dimensional plane or three-dimensional space.""The cartesian plane is a two-dimensional coordinate plane, formed by the intersection of the x-axis and y-axis."What is the distance of point from Y-axis?"The distance of a point from the Y-axis is its x-coordinate."
For given question,
Points A and B have opposite x-coordinates but the same y-coordinates.
Point A is 2 units to the left and 3 units up.
So the point A has coordinates (-2, 3)
Point B is 2 units to the right and 3 units up.
So the point B has coordinates (2, 3)
We know that the distance of a point from the y - axis is its x-coordinate.
So, the distance of point A from the y-axis is |-2| = 2 units
And the distance of point B from the y-axis is 2 units
Therefore, points A and B are 2 units away from the y-axis.

Your local radio station is having their yearly music player and concert ticket giveaway. For one minute, every 5th the caller will win a music player and every 7th caller will win concert tickets.
You were just the first caller to win both a music player and concert tickets!
What number of caller were you?
Answer:
you are the 35th caller.
Step-by-step explanation:
Multiples of 5: 5,10,15,20,25,30,35,40,45,50
Multiples of 7: 7,14,21,28,35,42,49,56,63,70
Since the question specified "first caller" , the answer is basically from the lowest common Multiple (the lowest number that appear in both multiples) , and in this case, only 35 is the lowest common multiple.
A town total allocation for firefighters wages and benefits in a new budget is $600,000. If wages are calculated at $40,000 per firefighter and benefits at $20,000 per firefighter. How many firefighters can the town employ if they spend their whole budget?
Answer:
Number of firefighters= 10
Step-by-step explanation:
Giving the following information:
Total budget= $600,000
Wage per firefighter= $40,000
Benefits per firefighter= $20,000
To calculate the number of firefighters that the town can employ, we need to use the following formula:
Number of firefighters= total budget / total cost per firefighter
Number of firefighters= 600,000 / (40,000 + 20,000)
Number of firefighters= 10
