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.

please help me. 5(m-7)=-8(3m+8)
Answer:
m = -1
Step-by-step explanation:
Solve for m:
5 (m - 7) = -8 (3 m + 8)
Hint: | Write the linear polynomial on the left hand side in standard form.
Expand out terms of the left hand side:
5 m - 35 = -8 (3 m + 8)
Hint: | Write the linear polynomial on the left hand side in standard form.
Expand out terms of the right hand side:
5 m - 35 = -24 m - 64
Hint: | Move terms with m to the left hand side.
Add 24 m to both sides:
24 m + 5 m - 35 = (24 m - 24 m) - 64
Hint: | Look for the difference of two identical terms.
24 m - 24 m = 0:
24 m + 5 m - 35 = -64
Hint: | Group like terms in 24 m + 5 m - 35.
Grouping like terms, 24 m + 5 m - 35 = (5 m + 24 m) - 35:
(5 m + 24 m) - 35 = -64
Hint: | Add like terms in 5 m + 24 m.
5 m + 24 m = 29 m:
29 m - 35 = -64
Hint: | Isolate terms with m to the left hand side.
Add 35 to both sides:
29 m + (35 - 35) = 35 - 64
Hint: | Look for the difference of two identical terms.
35 - 35 = 0:
29 m = 35 - 64
Hint: | Evaluate 35 - 64.
35 - 64 = -29:
29 m = -29
Hint: | Divide both sides by a constant to simplify the equation.
Divide both sides of 29 m = -29 by 29:
(29 m)/29 = (-29)/29
Hint: | Any nonzero number divided by itself is one.
29/29 = 1:
m = (-29)/29
Hint: | Reduce (-29)/29 to lowest terms. Start by finding the GCD of -29 and 29.
The gcd of -29 and 29 is 29, so (-29)/29 = (29 (-1))/(29×1) = 29/29×-1 = -1:
Answer: m = -1
Question 5
If you add me with another number our sums will be 13, our difference is 1, find us! Who is the Smaller Number?
Blank 1:
Question 6
If you divide me by 5 and decreace that value by 2, I am 25! What's My Number?
Blank 1:
Answer:
A . The numbers are 6 and 7, with the smaller number as 6
B. The number is 135
Step-by-step explanation:
A. Let the numbers be a and b
adding both gives 13
a + b = 13 •••••(i)
difference between the two is 1
b - a = 1 ••••••(ii)
So we have two equations that we can solve simultaneously;
b = 1 + a; Substitute this into 1
a + 1 + a = 13
2a + 1 = 13
2a = 13-1
2a = 12
a = 12/2
a = 6
b = a + 1 = 6 + 1 = 7
The numbers are 6 and 7 while 6 is the smaller number
B.Let the number be x
Divide by 5; x/5, then subtract 2 , we get 25
x/5 - 2 = 25
x/5 = 25 + 2
x/5 = 27
x = 5 * 27
x = 135

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.

how do you write a domain as an equation?
Answer: Answer
Step-by-step explanation: The domain of a function is all possible set inputs for a function. For example, if the function was {(10, 20), (10, 50), (11, 30)}, then the domains would be 10 and 11. Basically it is the first x value of each set.

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]
4x-20=mx-5m. find m
Answer:
[tex]m=4[/tex]
Step-by-step explanation:
So we have the equation:
[tex]4x-20=mx-5m[/tex]
First, factor out a m from the right:
[tex]4x-20=m(x-5)[/tex]
Divide both sides by x-5:
[tex]m=\frac{4x-20}{x-5}[/tex]
Factor out a 4 in the numerator:
[tex]m=\frac{4(x-5)}{x-5}[/tex]
The (x-5)s cancel. Thus:
[tex]m=4[/tex]
The value of m is 4 :)

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].

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
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.
