Answer:
14 days
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
25n+100=450
Step 2: Subtract 100 from both sides.
25n+100−100=450−100
25n=350
Step 3: Divide both sides by 25.
25n/25 =350/25
n=14
Answer:
Two weeks
Step-by-step explanation:
out of these 450, 100 are a flat, and it's 25 times the numer of days. In an equation form, [tex]450 = 100 + 25d[/tex]. The way you solve the equation, you subtract 100 to both sides, and divide by 25 (you can do it in the order you prefer!)

what is the distance between (5,8) and (2,4) by using distance formula
Answer:
Distance = 5
Step-by-step explanation:
D= sqrt (x1-x2)^2 + (y1-y2)^2
(5-2)^2 + (8-4)^2=3^2 + 4 ^2 = 9 +16 = 25
Sqrt of 25 = 5
Distance = 5

What is the domain of F
Answer:
-5 ≤x≤6
[-5,6]
Step-by-step explanation:
The domain is the values that the input takes
x goes from -5 (inclusive) to 6 (inclusive)
-5 ≤x≤6
[-5,6]
Answer:
[-5, 6]
Step-by-step explanation:
The domain of a function is the list of x values. Since the endpoints are shaded, that means those x values are included as well. Therefore, the domain of f is [-5, 6].

Find the slope of a line parallel to the line whose equation is y-4=7(x+2).
Answer:
m'=7
Step-by-step explanation:
they are parallel to each other so if slope of 1st line be "m" and 2nd line as "m' ", then we have:
m = m'
y-4=7x+14
y=7x+18
y=mx+h
So m = 7
& m' = 7
are 16/72 and 18/81 equivalent rational numbers
Answer:
yes
Step-by-step explanation:
[tex]\frac{16}{72}[/tex] ( divide numerator/ denominator by 8, the LCM of 16 and 72 )
= [tex]\frac{2}{9}[/tex]
[tex]\frac{18}{81}[/tex] (divide numerator/ denominator by 9 the LCM of 18 and 81 )
= [tex]\frac{2}{9}[/tex]
Both rational numbers simplify to [tex]\frac{2}{9}[/tex] and are equivalent

Let's solve your equation step-by-step.
x2+x=12
Step 1: Subtract 12 from both sides.
x2+x−12=12−12
x2+x−12=0
Step 2: Factor left side of equation.
(x−3)(x+4)=0
Step 3: Set factors equal to 0.

City planners are planning to build a new community pool. They agree that the pool will be rectangular in shape, but the proposed dimensions changed. At the most recent meeting, it was determined that the width would remain at 12.3 meters but that the length would increase by 4.3 meters. So, the pool would now cover an area of 213.65 square meters. Which equation can be used to determine the original length of the pool, I?
A. 213.65 = 4.3(1+ 12.3)
B. 213.65(I+16.6)
C. 213.65 = 12.3(I+ 4.3)
Answer:
C. 213.65 = 12.3(I+ 4.3)
Step-by-step explanation:
Original length: l
New length: l + 4.3
area: LW
area: 213.65 m²
area = LW = (l + 4.3)(12.3)
(l + 4.3)(12.3) = 213.65
12.3(l + 4.3) = 213.65
Answer: C. 213.65 = 12.3(I+ 4.3)

Use the ratio to find the measurement. (4 points: 1 point for the method, 2 points for shown work, 1 point for the answer)
6. Confirm that your answer to question 5 is correct using the Pythagorean Theorem instead of trig ratios. (3 points)
Answer:
The trigonometric ratio that I would use to find the distance from the base of the tower to the keys is the tangent; tan (86°) = height / distance.
Step-by-step explanation:
You can draw a right triangle with angle 86°, opposite leg equal to the height (50 meter) and adjacent leg equal to the distance from the base of the tower to the keys: tan (86°) = 50 m / x
=> x = 50 m / tan(86°)
x = 50 m / 14.30 = 0.98 m

Answer:
4 : 1
Step-by-step explanation:
Each segment joining midpoints is called a "midline." It is parallel to the segment not being joined, and is half its length. All the dimensions of the smaller triangle are half those of the larger triangle. (They are similar triangles.) The ratio of areas is the square of the ratio of side lengths:
