14. Rob uses free weights at the gym every 3 days and he uses the weight machines every 5 days.
Today Rob used both free weights and the weight machines. How many days will it be before he uses
both kinds of weights on the same day again?

Answer:

We note that the equation that is compatible with the given equation is the kinematic equation of free fall where;

t² = 39.2 × 2/9.81

From which we have;

The time it takes the snowball to reach the ground is approximately 2.83 seconds

Step-by-step explanation:

The height of the building from which the ball is dropped, h = 39.2 m

The equation of the dropped a snowball, is given as follows;

t² = 39.2 × 9.8

Using the From the equation of free fall, we have;

s = u·t + 1/2·g·t²

Where;

u = The initial velocity = 0 m/s

t = The time of flight

g = The acceleration due to gravity = 9.81 m/s²

Therefore, we get;

∴ s = The height from which the snowball is dropped = 39.2 m

Therefore, we get;

39.2 = 0×t + 1/2×9.81×t²

∴ t² = 39.2 × 2/9.81  ≈ 7.99

t = √(7.99) ≈ 2.83

The time it takes the snowball to reach the ground, t ≈ 2.83 s.

Answer:

2 seconds

Explanation:

I had to do this assignment that's the correct answer

Answer:

B. 50 degrees

Step-by-step explanation:

I am not 100% sure and if this is a right triangle, then it's measure is 90 degrees. So, 140 degrees minus 90 degrees would total, 50 degrees.

Answer:

B: 50 degrees

Step-by-step explanation:

You first find the other angles of the triangle. One is 90 degrees at the corner. The other would be 40 because the outside angle is 140 and that is 40 away from 80. Add 40 and 90 together to get 130 degrees. Subtract that from 180 and that is 50 degrees :)

Hope this helps!

Answer:

1/6 mile

Step-by-step explanation:

Distance divided = 1/2 miles

No of sections = 3

Each division must equal = 1/2/3

                             = 1/2*1/3 = 1/6 mile.

The distance between each of the signs i.e between the first and second , second and third is 1/6 of the mile.

This can be done in decimals as well

1/2 mile= 0.5 mile.

When we divide 0.5 mile by 3 we get  0.167 which is equal to 1/6 in fractions.

Answer: 0.4

Step-by-step explanation:

If the height of the first bounce is 5.5, then you find what 60% of 5.5 is and to do that you do 60/100 and x/5.5 so cross multiply 60x5.5 to get 330 then divide by 100 to get 3.3 and you do that 5 more times to get 0.42768 which when rounded to the tenths place, gets you 0.4

Answer:

4(3+x)

Step-by-step explanation:

12+4x = 4(3+x)

Answer:

m = 5.3

Step-by-step explanation:

Given equation,

→ m = 0.4n - (2/3)

Now we have to,

→ Find the required value of m.

We have to use,

→ n = 15

Then the value of m will be,

→ m = 0.4n - (2/3)

→ m = 0.4(15) - (2/3)

→ m = 6 - (2/3)

→ m = (18/3) - (2/3)

→ m = (18 - 2)/3

→ m = 16/3

→ [ m = 5.3 ]

Hence, the value of m is 5.3.

Answer:

30 cm

Step-by-step explanation:

1. Given the length, width and tallness discover the volume, surface region and inclining of a rectangular crystal  

h, l and w are known; discover V, S and d  

V = lwh  

S = 2(lw + lh + wh)  

d = √(l2 + w2 + h2)  

2. Given the surface region, length and width discover the tallness, volume and askew of a rectangular crystal  

S, l and w are known; discover h, V and d  

h = (S - 2lw)/(2l + 2w)  

V = lwh  

d = √(l2 + w2 + h2)  

3. Given the volume, length and width discover the stature, surface territory, and slanting of a rectangular crystal  

V, l and w are known; discover h, S and d  

h = V/lw  

S = 2(lw + lh + wh)  

d = √(l2 + w2 + h2)  

4. Given the inclining, length and width discover the tallness, volume and surface space of a rectangular crystal  

d, l and w are known; discover h, V and S  

h = √(d2 - l2 - w2)  

V = lwh  

S = 2(lw + lh + wh)

Answer:

S = 6

I think

Answer:

s=6

Step-by-step explanation:

if you are figuering it out in order then r=26 then you subtract 10 and get h=16 so then you subtract 6 more and get s=6

Answer:

Ive done those before the first one is 7 and the second one is 4

Step-by-step explanation:

0=(-9)

Step-by-step explanation:

4x + 7 = -2 + 4x

4x + 7 = 4x -2

subtract 7 from both sides of the equation.

simplify your answer.

subtract 4x from both sides of the equation.

simplify your answer again.

4x + 7 = 4x -2

___-7 = 4x -7

4x __ = 4x -9

__4x = 4x -9

-4x = -4x -9

__0 = -9

the input is a contradiction: it has no solutions.

A. f(x)=(x+5)(x-1)

Answer:

the correct option is 75

Step-by-step explanation:

The standard notation for how to write tables is in the next way.

[tex]\left[\begin{array}{ccc}inpt&outpt\\x_1&y_1\\x_2&x_2\end{array}\right][/tex]

Where the input values are represented in the x-axis (the horizontal one) and the output values are on the y-axis (the vertical one).

In this case, we want to find the number of (x-value) for the height of 250.

Then we need to look at the vertical axis and find the value y = 250.

Now let's move to the right until you meet with the point.

Once you reach the point, move down to the axis, the value at which you intersect the axis is the x-value.

We can see that the point is on the middle of the x-values:

x = 70 and x = 80

Then the x-value of the point is x = 75

This means that the correct option is 75

Answer:

9/8

Answer:

x=-3 is not a solution

Step-by-step explanation:

well, lets plug it and and see!

6(-3)-19=3(-3)-10

-18-19=-9-10

-37=-19

-37 DOES NOT equal -19.

so x=-3 is not a solution
