Since 60 minutes are in 1 hour, we can do (0.08 km/1 min)*(60min/1 hour) and cross out the minutes, getting (0.08*60 km)/(1 hour)= 4.8km/1 hour. Since 1.61 kilometers are in 1 mile, we can multiply the equation by 1mile/1.61 km (since they are equal) and cross out the km to get 4.8*1.61miles/1 hour= \
7.728mi/1 hour. Since it's closer to 8 than 5, 3, or 2, D is right

What does x equal? Please help. No trolls
aniked [119]

Answer:

The value of 'x' is 17.

Step-by-step explanation:

Given:

Δ IJK ≅ ΔPQR

m∠I = 3x + 4

m∠P = 72 - x

To Find:

x = ?

Solution:

Δ IJK ≅ ΔPQR ...........Given

If two triangles are congruent then the corresponding angles of congruent triangles are congruent.

∴∠ I ≅ ∠ P ........corresponding parts of congruent triangle (CPCT)

Substituting the values we get

3x+4=72-x\\\\3x+x=72-4\\\\4x=68\\\\\therefore x=\dfrac{68}{4}=17\\\\\therefore x =17

The value of 'x' is 17.

Martin is asked to find the probability of getting one head and three tails on for coin tosses this is a simple event
Georgia [21]
The possible outcomes for 1 HEAD and 3 TAILS are

HTTT
THTT
TTHT
TTTH

Assuming the coin is a fair coin, we have:
Probability of tossing head is 0.5
Probability of tossing tail is 0.5

Probability of tossing the coin four times for each outcome combination listed above is

HTTT = 0.5×0.5×0.5×0.5 = 0.0625
THTT = 0.5×0.5×0.5×0.5 = 0.0625
TTHT = 0.5×0.5×0.5×0.5 = 0.0625
TTTH = 0.5×0.5×0.5×0.5 = 0.0625

Hence, probability of getting three tails and one head from 4 tossing is 
4×0.0625 = 0.25

Travka [436]
45 because 1set equals 3 push ups and she did ten sets so 10sets equal 30 push ups and then her coach asked her to do 15 more so 30 plus 15 equals 45 so she did 45 push ups that day!
