Answer:

Paul has five counters.

Step-by-step explanation:

Paul has an unknown number of counters.

Paul has two less than seven counters.

Let's see the attached drawing. A total number of seven counters.

If we have two less than seven, it means that of the total seven counters, we have to delete two.

C = 7 -2 = 5

So, Paul should have five counters.If we delete the red boxes, we can see the five counters.

This is very simple mathematics. The statement: two less than seven translates to
seven minus two which in arithmetic form is
7 - 2
which is equal to
7 - 2 = 5
Therefore, the number counters that Paul has is 5.<span />

A hot-air balloon is moving on a bearing of 2450 at 31mph. A wind is blowing with the bearing of 2600 at 23mph. Find the compone

Alborosie

Answer:

$V=(54i) \ mph$

Step-by-step explanation:

According to the problem, the hot-air ballon and the wind are movind in the same direction, which means the component form of the velocity of the ballon is the net vector between both velocities.

Basically, the net velocity is

$v_{net}=31 + 23 = 54 mph$

Because both velocities have the same direction.

Assuming they are moving in a horizontal direction, the component of this velocity is

$V=(54i) \ mph$

Graph the six terms of a finite series where a1 = -3 and r = 1.5.

zavuch27 [327]

A1 is the 1st term
r is the difference, they can say "r" or "d" for the difference

1st a1 is the first term = -3
2nd "r" is the difference between each consecutive terms (coming after each other) = 1.5
the rule to get any term of the sequence as we add 1.5 each time is --> a1+(n-1)*d
a1 --> 1st term , n --> order of the term u want whether 2nd, 3rd , 25th
d --> difference
so to get the 2nd--> -3+(2-1)*1.5= -1.5
to get the 3rd --> -3 +(3-1)*1.5 = 0
<span>and so on </span>

A: {71,73,79,83,87} B:{57,59,61,67}

Jobisdone [24]

Answer:

$\frac{3}{5}$ .

Step-by-step explanation:

We have been given two sets as A: {71,73,79,83,87} B:{57,59,61,67}. We are asked to find the probability that both numbers are prime, if one number is selected at random from set A, and one number is selected at random from set B.

We can see that in set A, there is only one non-prime number that is 87 as it is divisible by 3.

So there are 4 prime number in set A and total numbers are 5.

$P(\text{Prime number from A})=\frac{4}{5}$

We can see that in set B, there is only one non-prime number that is 57 as it is divisible by 3.

So there are 3 prime number in set B and total numbers are 4.

$P(\text{Prime number from B})=\frac{3}{4}$

Now, we will multiply both probabilities to find the probability that both numbers are prime. We are multiplying probabilities because both events are independent.

$P(\text{Prime number from A and B})=\frac{4}{5}\times \frac{3}{4}$

$P(\text{Prime number from A and B})=\frac{1}{5}\times \frac{3}{1}$

$P(\text{Prime number from A and B})=\frac{3}{5}$

Therefore, the probability that both numbers are prime would be $\frac{3}{5}$ .

A store is having a sale on jelly beans and trail mix. For 3 pounds of jelly beans and 2 pounds of trail mix, the total cost is

klasskru [66]

3j+2t=14 subtract 2t from both sides

3j=14-2t divide both sides by 3

j=(14-2t)/3

...

5j+6t=28, using j found above in this equation yields.

5(14-2t)/3+6t=28 perform indicated multiplication on left side

(70-10t+18t)/3=28 multiply both sides by 3

70-10t+18t=84 combine like terms on the left side

70+8t=84 subtract 70 from both sides

8t=14 divide both sides by 8

t=$1.75, and since j=(14-2t)/3

j=(14-2(1.75))/3

j=$3.50

So a pound of trail mix costs $1.75 and a pound of jelly beans costs $3.50.
