7x (3+5+ ? --> (7x3) + (7x5) = ?
____+____=_____
Answer:
112
Step-by-step explanation:
(3=5=8) so it would be 7x8= 56. 7x3= 21. 7x5=35. So that would mean you have to add 56,21,and 35
56+21+35= 112
(simplified expression) 77+35=112
You have a deck of cards and draw three cards one after the other without replacing the cards. What is the probabilities of drawing three tens? (Pls give a good explanation & the answer lol)
Answer:
The probability of drawing 3 tens one after another without replacing them is 1/5525
Step-by-step explanation:
In a pack of 52 cards, there are 4 cards that are 10, so the probability of drawing one ten [p(10)] = 4/52
Therefore:
The first draw, P(10) = 4/52
Now, at this point you have taken out one of the cards with a number 10 printed on it, so we are left with 51 cards in total and 3 cards of 10.
The second draw, p(10) = 3/51
Now, we have 50 cards left and a total of 2 cards with a number 10 printed on it.
The third draw, p(10) = 2/50
Hence, the probability of drawing out 3 number 10 cards without replacement is:
4/52 * 3/51 * 2/50 = 1/5525
The probability of drawing 3 tens one after another without replacing them should be 1/5525.
Calculation of the probability:Since we know that
In a pack, there are 52 cards and there are 4 cards that are 10,
so the probability of drawing one ten [p(10)] = 4/52
Now it should be left with 51 cards in total and 3 cards of 10.
So, The second draw, p(10) = 3/51
and, The third draw, p(10) = 2/ 50
Thus, the total probability is
= 4/52 * 3/51 * 2/50
= 1/5525

Step-by-step explanation:
Just subtract
Answer:
1/3
Step-by-step explanation:
Subtract the numerators 11 by 7 and get 4/12 which is your new fraction. Simplify by dividing each number by 4. 4 divided by 4 is 1, and 12 divided by 4 is 3. So your answer is 1/3.

A. Find the circumference of the tire.
B. About how many times will the tire have to rotate to travel 1 mile? (1 mile = 5,280 ft)
Answer:
Answer Below
Step-by-step explanation:
The diameter of a tire is 2.5 ft. a. Find the circumference of the tire. b. About how many times will the tire have to rotate to travel 1 mile?
a) The circumference of a circle is the perimeter of the circle. The circumference of the circle is the distance around a circle, that is the arc length of the circle. The circumference of a circle is given by:
Circumference = 2π × radius; but diameter = 2 × radius. Hence:
Circumference = π * diameter.
Given that diameter of the tire = 2.5 ft:
Circumference of the tire = π * diameter = 2.5 * π = 7.85 ft
b) since the circumference of the tire is 7.85 ft, it means that 1 revolution of the tire covers a distance of 7.85 ft.
1 mile = 5280 ft
The number of rotation required to cover 1 mile (5280 ft) is:
number of rotation = 5280 ft/7.85 ft per rotation = 672 rotations.

I need a set of coordinates to model a relation that is a linear function quick please.
Answer:
y=2x+1
Step-by-step explanation:
The linear function is a function that has a straight line graph.
Response:
A set of coordinate that model a linear function is presented as follows;
{(0, 5), (1, 8), (2, 11), (3, 14), (4, 17), (5, 20)}Method by which the above set of coordinates is obtainedA linear function is a function that can be written in the form; y = m·x + c
Where;
m = The slope of the graph is a constant
c = The y-intercept of the graph is a constant
Therefore,
Therefore, a set of coordinates can be obtained by setting the values of m and c as follows;
When m = 3, and c = 5, we have;
y = 3·x + 5
Using the above equation, we get;
[tex]\begin{tabular}{|c|c|} \underline{x} & \underline{y = 3 \cdot x + 5}\\0&5\\1&8\\2&11 \\3&14\\4&17\\5&20\end{array}\right][/tex]
Using the above table of values, a set of coordinates that model a linear function is therefore;
{(0, 5), (1, 8), (2, 11), (3, 14), (4, 17), (5, 20)}

Megan wants to give each guest at her birthday party three mini-
cans of Play-Doh. The cans are sold in bags of nine for $2.86. If there
are thirty-six guests at her party, how much will it cost to give three
mini-cans of Play-Doh to each guest?
Number of guests to be invited in the birthday party = 36
Megan wants to given 3 cans of Pay-Doh to each guest.
Therefore, number of cans to be given = 3 × 36 = 108
Since, cans are sold in the pack of 9, number of packs required = [tex]\frac{108}{9}[/tex]
= 12
Since, cost of each pack of cans = $2.86
Therefore, total cost of 12 packs = 12 × 2.86
= 34.32

Jayden used a Groupon at the local pizza shop. Instead of paying $15, for the pizza, he paid $12.
Haley and Arianna agree that the percent of decrease is 20% but their explanations differ. Haley says to find the 20%, you have to determine what percent of 15 is 12. Arianna thinks you have to determine what percent of 15 is 3. Who is correct? Explain your thinking.
Answer:
She is correct because they need to find how much is the discounted price, which is 3. So to see what percentage it is, they need to see how much 3 is worth in comparison to 15. If we spilt 15 into 5 parts to make every part worth 20%, the answer would be 3. Thus Arianna is correct.
