pentagon [3]3 years ago
3 0

Answer: I believe it the probability of this would be 1/3.

Step-by-step explanation: This is mainly because if the chances of rolling a 5 or a 4 on a die or fair numbered cube, which contains 6 sides, then landing on 5 or 4 would be 2 out of the six chances it would land on those two numbers. Hope this helps!

Yakvenalex [24]

Answer:

Each of them spent $9.35 on meal.

Step-by-step explanation:

Jacob and his three friends ordered an individual pizza and a drink for $6.19.

Total cost of pizza and drink = 6.19 × 4

= $24.76  

They also ordered bread sticks for $4.25

Tax on the bill was = $2.39

Tip amount was = $1.50×4 = $6.0

So the total billed amount will be = 24.76 + 4.25 + 2.39 + 6

= $37.4

Since there were four persons including Jacob.

Therefore, each person spend on meal = \frac{37.40}{4}

= $9.35

The houck family's train traveled 552 miles in 6 hours. The Roberts family traveled at 744 miles in 8 hours which family is trav
rusak2 [61]

Answer: Both families were travelling at the same speed/rate of 1mile/0.65mins or 1mile/0.01hr.

Step-by-step explanation: Speed of Houck family's train = 552m/6hrs

speed of Robert family's train = 744m/8hrs.

Therefore considering Houck speed,

552miles = 6hours

1mile = (6 x 60)/552

= 360/552

= 0.65minutes. Average speed = 1mile/0.65mins. Or 1mile/0.01hr

For Robert

744miles = 8hours

1mile = ( 8 x 60 )/744

= (480/744)minutes

= 0.645

= 0.65minutes. Average speed = 1mile/0.65mins. Or 1mile/0.01hr

Conclusion: Both families were travelling at the same speed/rate.

To get that minutes in hour, just divide by 60 to get concert to hours.

An angle measures 16° more than the measure of its supplementary angle. What is the measure of each angle?
Olenka [21]
82 degrees and 98 degrees


First, find the original equation

180 = (x) + (x + 16)


Simplify: 180 = 2x + 16


Next, use the subtraction property of equality to subtract 16 from both sides


180 - 16 = 2x + 16 - 16


Simplify: 164 = 2x


Then, you can use the division property of equality to find the value of x

164/2 = 2x/2


Simplify: 82 = x



Now, we know that the first angle equals 82 degrees and that the second angle equals 98 degrees
