HELP PLEASE solve for d
Answers
d= 1- 4bh
Step-by-step explanation:
- 8b = 2d - 2/h
Multiply both sides of the equation by h.
- 8bh = 2d - 2
Swap sides so that all variable terms are on the left-hand side.
2d - 2 = - 8bh
Add 2 to both sides.
2d = - 8bh + 2
The equation is in standard form.
2d = 2 - 8bh
Divide both sides by 2.
2d/2 = 2 - 8bh/2
Dividing by 2 undoes the multiplication by 2.
d = 2 - 8bh/2
Divide -8bh + 2 by 2.
Therefore: d = 1 - 4bh

30. 480
The way I got 480 was I converted 8 hours into minutes because you want the same value of measurement.
After this, just cross multiply and you get the equation
46560 = 30mile
Then just isolate the miles (because you are trying to solve for 1 mile
Miles = 1,552
30 minutes is half of an hour so first you need to multiple 8•2 then you multiple 97 by what 8•2 is (16) that gets you 1552
what is perfect cube
Answers
Answer:
The perfect cube is the result of multiplying the same integer three times. Multiplying the number 4 three times, for example, yields 64. As a result, the number 64 is a perfect cube. Perfect cube = number x number x number.
Step-by-step explanation:
Perfect cube numbers can be obtained by multiplying every number thrice by itself. For example, 1 × 1 × 1 = 1 and 2 × 2 × 2 = 8 and so on. The list of perfect cubes from 1 to 10 is as follows: 1, 8, 27, 64, 125, 216, 343, 512, 729, and 1000.

Jack’s recipe calls for One-half teaspoon of baking powder. He cannot find the One-half teaspoon measuring spoon. Instead, Jack uses the One-eighth teaspoon measuring spoon to add Three-eighths teaspoon of baking powder. Which statement is true? Jack should stop adding baking powder because One-eighth equals . Jack should add more baking powder because Three-eighths is less than One-half. Jack should add more baking powder because Five-eighths is less than One-half. Jack has added too much baking powder because is greater than .

WHAT TYPE OF MATH LIKE WHAT LESSON
Step-by-step explanation:
|-The output for 4 is 10
|-the output for the three dots is 13
|-the output for N is 16
If you look at the output for the previous numbers, 1, 4, and 7- you notice that 1+3=4 and 4+3=7, assuming this may be a rule, you can add 3 to 7 which gets you 10, continuing on 10+3=13 and 13+3=16. Next for the input try to see what the input and output have in common. 1 and 1, 2 and 4 and 3 and 7. 1+0=1 2+2=4 3+3=6(+1) =7 4+4=8 (+2)=10 (continue this for the three dots) 5+5=10 (+3)=13. Because of this the input for the three dots would be 5. For N, it would be 6+6=12(+4)=16, so the input for N would be 6.

Step-by-step explanation:
m∠DCR is an exterior angle of the triangle DCE
Solving For Exterior Angles:To find the value of an exterior angle, we must sum up the two opposite (corresponding) angles inside the triangle
In this case, 2x + 7 and 26 are the corresponding angles
Solve:6x - 7 = 2x + 7 + 26
4x - 7 = 7 + 26
4x = 14 + 26
4x = 40
x = 10°
Your answer : x = 10°-Chetan K
A Mars rover traveled from point A to point B at a speed of 4 cm/sec. Worsening conditions during the return trip caused the rover to travel at a speed of 2.5 cm/sec, and increased travel time by 15 minutes. What is the distance between point A and point B?
Answers
Using the speed - time relation, the distance between point A and B is 6000 cm
Recall :
Distance = speed × time Time = distance / speedLet ; the time taken = t ; distance = d
To trip :
d = 4t ----(1)Fro trip :
t is in seconds ; 15 minutes = (15×60) = 900 secondsd = 2.5(t + 900)
d = 2.5t + 2250 - - - - - (2)
Equating (1) and (2)
4t = 2.5t + 2250
Collect like terms
4t - 2.5t = 2250
1.5t = 2250
t = 2250 / 1.5
t = 1500 seconds
Hence, distance = 4(t) = 4(1500) = 6000 cm
Therefore, the distance between the points is 6000 cm
