Answer:

-21

Step-by-step explanation:

I used the backward method

She adds 8 to get 5.

So we start with 5 and subtract 8

5-8 = -3

She divides by 7 but since we are using the backwards method, we have to multiply.

-3*7= -21

After that, we can check our answer

Krutika was thinking of -21

-21/7= -3

-3+8= 5

-21 is the answer

Hope this helps!

All sides of an equilateral triangle are equal, so all three sides are 9 cm.
To find h, use the pythagorean theorem. This requires use of only one right triangle, where we use b as our h.

a^2+b^2=c^2
(4.5)^2+b^2=(9)^2
(20.25)+b^2=(81)
b^2=(81/20.25) or 4
square root both sides
b=2

Koshanah rode her bike for 35 minutes on monday, wendsday, and saterday and 55 minutes each on tusday and thersday . Write an ex

dem82 [27]

Answer:

215 minutes

Step-by-step explanation:

Let

Number of days she rode for 35 minutes = x

Number of days she rode for 55 minutes = y

Total time spent riding her bike = 35x + 55y

x = Monday + Wednesday + Saturday

x = 3 days

y = Tuesday + Thursday

= 2 days

Substitute into the equation

Total time spent riding her bike = 35x + 55y

= 35(3) + 55(2)

= 105 + 110

= 215 minutes

On Mars the acceleration due to gravity is 12 ft/sec^2. (On Earth, gravity is much stronger at 32 ft/sec^2.) In the movie, John

insens350 [35]

Solution :

Given initial velocity, v= 48 ft/s

Acceleration due to gravity, g = $12\ ft/s^2$

a). Therefore the maximum height he can jump on Mars is

$H_{max}=\frac{v^2}{2g}$

$H_{max} = \frac{(48)^2}{2 \times 12}$

= 96 ft

b). Time he can stay in the air before hitting the ground is

$T=\frac{2v}{g}$

$T=\frac{2 \times 48}{12}$

= 8 seconds

c). Considering upward motion as positive direction.

v = u + at

We find the time taken to reach the maximum height by taking v = 0.

v = u + at

0 = 16 + (12) t

$t=\frac{16}{12}$

$=\frac{4}{3} \ s$

We know that, $S=ut + \frac{1}{2}at^2$

Taking t = $=\frac{4}{3} \ s$ , we get

$S=16 \times\frac{4}{3} + \frac{1}{2}\times(-12) \times \left(\frac{4}{3}\right)^2$

$S=\frac{32}{3}$ feet

Thus he can't reach to 100 ft as it is shown in the movie.

d). For any jump whose final landing position will be same of the take off level, the final velocity will be the initial velocity.

Therefore final velocity is = -16 ft/s
