Answer:
domain is (xo ≤ x ≤ 0.45 )
range is (xo ≤ y ≤ 8.1 )
Step-by-step explanation:
given data
constant speed = 18 miles per hour
total time = 27 minutes = 0.45 hour
solution
we consider here Domain number of hours = x and Range distance traveled = y
we apply here distanace formula that is
Distance = speed × time .........................1
put here value
Distance = 18 × 0.45 = 8.1 miles
and no of hours x = 0 to 0.45 hours
so here
So domain is (xo ≤ x ≤ 0.45 )
and
Distance is 0 to 8.1 miles
So range is (xo ≤ y ≤ 8.1 )
The endpoints of AB are 8 and 16. Find the coordinate of the point P that partitions the segment in the ratio 3 : 1
The coordinate of point P is
Answer:10
Step-by-step explanation:
Answer and Step-by-step explanation:
Sol: the ratio formula is
x-x1/x2-x = ratio and y-y1/ y2-y= ratio
x-(-7)/0-x=2/1 and y-17/0-y=2/1
x+7=2(-x) and y-17 = -2y
x+2x=-7 and y+2y =17
3x=-7 and 3y = 17
x=-7/3 and y= 17/3
coordinates of point p that partition the segment in ratio is (-7/3, 17/3)
The midpoint formula is:
M= (x1+x2/2, y1+y2/2)
= (-7+0/2, 17+0/2)
= (-7/2, 17/2) are the midpoint of AB.

You are an influencer on Instagram. Company A pays you
$5000 per post advertising their product. Company B pays you $2500 per post advertising their product.
You make 3 posts for Company A. How many posts do you have to make for Company B in order to earn
$25000 from advertising on Instagram?
Hi
3*5000 +X*2500 = 25 000
15 000 + 2 500X = 25 000
2 500X = 25 000 - 15 000
2 500 X = 10 000
x = 10 000 / 2 500
X = 100/25
X = 4
You need 4 post for B
3*5000 + 4* 2 500 = 15 000 + 10 000 = 25 000
Laura says that the distance between (4,-2) and (4,-7) in the coordinate plane is equal to |-2-(-7)|units Ryan say that the distance between (2,3) (-9,3) in the coordinate plane is equal to |2+9| units is either Laura or Ryan correct explain
Answer:
Both are correct.
Step-by-step explanation:
In the point (4,-2) and (4,-7), the x-coordinates are same. So, the distance between these points is the absolute difference between the y-coordinates of these points.
[tex]Distance=|-2-(-7)|=5\text{ units}[/tex]
So, Laura is correct.
In the point (2,3) and (-9,3), the y-coordinates are same. So, the distance between these points is the absolute difference between the x-coordinates of these points.
[tex]Distance=|2-(-9)|=|2+9|=11\text{ units}[/tex]
So, Ryan is correct.
Hence, both are correct.

An object is moving at a speed of 230 feet per week. Express this speed in inches per minute. Round your answer to the nearest hundredth
Answer:
0.02 inches per minute
Step-by-step explanation:
1 Week = 10080 minutes
Formaul: multiply the time value by 10080 to find the minutes in a week or do it the long way 60x24x7 = 10080
230/10080 = 0.02281746031 or 0.02 rounded to nearest hundert.

solve for the indicated variable A=r+rvf for v
Answer:
[tex]v = \frac{A - r}{rf}[/tex]
Step-by-step explanation:
Given
[tex]A = r + rvf[/tex]
Required
Solve for v
[tex]A = r + rvf[/tex]
Subtract r from both sides
[tex]A - r = r - r + rvf[/tex]
[tex]A - r = rvf[/tex]
Divide both sides by rf
[tex]\frac{A - r}{rf} = \frac{rvf}{rf}[/tex]
[tex]\frac{A - r}{rf} = v[/tex]
Reorder the expression
[tex]v = \frac{A - r}{rf}[/tex]
At this point, we;ve solved for v

the price of gravel is $24 for every 3/8 ton. Kate wants to know the price of 2 tons of gravel. at that rate, what is the price of 2 tons of gravel
Answer:
$128Step-by-step explanation:
This problem is on rate.
firstly we have to find the rate at which 1 ton is sold
given that 3/8 ton is sold for $24
hence 1 ton will be sold for X
cross multiply
X = 24/3/8
inverse the denominator and multiply the result with the numerator we have
X= 24*8/3
X= $64
Now having found out that 1 ton cost $64
2 tons will cost =64*2
= $128
Therefore at this rate two tons will cost $128
Answer:128

Tim's bean sprout grew 3/ inches. Teegan's bean sprout grew 2 3/4 inches. How many more inches did Tim's bean sprout grow than Teegan's? First, estimate the difference mentally and explain your reasoning. Then find the actual difference.
Answer:
Tim's bean sprout grow by more than [tex]\frac{5}{8} \text{ inches}[/tex].
Step-by-step explanation:
We are given that Tim's bean sprout grew 3 3/8 inches. Teegan's bean sprout grew 2 3/4 inches.
We have to find how many more inches did Tim's bean sprout grow than Teegan's.
Firstly, converting both the mixed fractions in improper fraction get;
Tim's bean sprout grew = [tex]3\frac{3}{8}[/tex] = [tex]\frac{27}{8} \text{ inches}[/tex]
Teegan's bean sprout grew = [tex]2\frac{3}{4}[/tex] = [tex]\frac{11}{4} \text{ inches}[/tex]
Since the denominator of both the fractions is not the same, so we can't compare them both as which is larger or smaller.
Tim's bean sprout grew = [tex]\frac{27\times 1}{8\times 1} = \frac{27}{8} \text{ inches}[/tex]
Teegan's bean sprout grew = [tex]\frac{11 \times 2}{4\times 2}=\frac{22}{8} \text{ inches}[/tex]
Now, we can clearly see that Tim's bean sprout grew more than Teegan's bean sprout.
So, Tim's bean sprout grow by more than = [tex]\frac{27}{8}- \frac{22}{8}[/tex] = [tex]\frac{5}{8} \text{ inches}[/tex]
Hence, Tim's bean sprout grow by more than [tex]\frac{5}{8} \text{ inches}[/tex].

d=18+34 d=22t system of equations
Answer:{d,t}={187, 17/2}
Step by step explanation :
System of Linear Equations entered :
[1] d - 18t = 34
[2] d - 22t = 0
Graphic Representation of the Equations :
-18t + d = 34 -22t + d
Solve by Substitution :
// Solve equation [2] for the variable d
[2] d = 22t
// Plug this in for variable d in equation [1]
[1] (22t) - 18t = 34
[1] 4t = 34
// Solve equation [1] for the variable t
[1] 4t = 34
[1] t = 17/2
// By now we know this much :
d = 22t
t = 17/2
// Use the t value to solve for d
d = 22(17/2) = 187
Answer:
[tex]d=52\\t=\frac{26}{11}[/tex]
Step-by-step explanation:
1 solve for d in d =18+34
solve for d
[tex]d=18+34[/tex]
Simplify 18+34 to 52
[tex]d=52[/tex]
2 substitute d=52 into d=22t
Start with the original equation
[tex]d=22t[/tex]
Let d=52
[tex]52=22t[/tex]
3 Solve for t in 52=22t
Solve for t
[tex]52=22t[/tex]
Divide both sides by 22
[tex]\frac{52}{22} =t[/tex]
Simplify [tex]\frac{52}{22}[/tex][tex]to \frac{26}{11}[/tex]
[tex]\frac{26}{11} =t[/tex]
Switch sides
[tex]t=\frac{26}{11}[/tex]
4 Therefore
[tex]d=52\\t=\frac{26}{11}[/tex]
Simplify. 4−16÷4+42 −16 13 15 16
Answer:
[See Below]
Step-by-step explanation:
✦ First split the equation in little pieces and solve them:
✧ 4 - 16 = -12
✧ 4 + 4² = 20 (4² = 16)
✦ Now divide them:
✧ -12 ÷ 20 = -0.6
So I'm guessing you're trying to simplify 4²... so it'd be 16 because none of the choices are the simplified version of the problem.
