Write each expression using exponents x·x·x·x·y·y
Answer:
x^4*y^2
Step-by-step explanation:
Whenever you multiply a number by itself, add one to its power. X is actually x^1, but we don't write that. Keep on adding 1 to the power for every x you multiply together and do the same thing for y. You will get x^4*y^2 as the answer.
Answer:
x^4y^2
Step-by-step explanation:
because you have 4 x so you put x^4 and you have 2 y so you do y^2 which the answer is x^4y^2

A recipe for fruit calls for 2 cans of pineapple juice and 3 cans of orange juice. Hiri is making a large batch for a community function and uses 72 cans of orange juice. How many cans of pineapple juice should he use?
Answer:
48 cans of pineapple juice he should use.
Step-by-step explanation:
This, is a problem of ratio where we have to use the concept
a:b = c:d which can be also written as
a/b = c/d
______________________________________________________
According recipe
we find ratio of pineapple and orange juice
amount pine apple juice : amount of orange juice = 2 cans : 3 cans
Thus, ratio of pineapple and orange juice = 2:3
___________________________________
Given that this recipe is used for making juice in large batch for a community function
Given
amount of orange juice = 72 cans
let the amount of pine apple juice be x
ratio of pineapple and orange juice in this case
amount pine apple juice : amount of orange juice = x cans : 72 cans
ratio of pineapple and orange juice in this case= x : 72
since recipe used is same.
ratio will be same in both case that in recipe ratio and large batch preparation for community function
Thus,
x:72 = 2:3
which can also be written as
x/ 72 = 2/3
x = 2/3 * 72 = 48
Thus, 48 cans of pineapple juice he should use.
Hillside Travel pays its employees $10 per hour plus 8% commission on all trips booked. Tyrus worked 20 hours last week and booked trips amounting to $2,100. What was his gross pay for last week? *
Answer:
$368
Step-by-step explanation:
Well, if they pay their employees $10 per hour, and Tyrus worked 20 hours, then we have a base amount of 200, as 10*20=200. Next, we need to think about the 8% commission from 2100, so we multiply 2100*.92 to get 1932 so 2100-1932=168. So, to get the gross pay, you add the base amount, 200, and the commission, 168, together to get $368. Tyrus got a gross pay of 368 dollars last week.
twice the sum of a number and 400. Translate the verbal expression into an algebraic expression plz
Answer:

6 Friends all use two dollars off coupon to buy them selves movie tickets they spend a total of $42 what is the price of one movie ticket without the coupon
Answer:
The answer is $7
Step-by-step explanation:
The answer is $7 because $42 divided by 6 = 7.
Answer:
The price of one movie ticket without a coupon would be $9.
Step-by-step explanation:
one movie ticket: x
$42 = 6(x- 2)
$42 = 6x- $12
Move the 12 to the other side.
42 = 6x - 12
+ 12 +12
____________
54 = 6x
Now divide 6 from both sides.

[tex]x = \frac{2 + \sqrt{10} }{3} \: \: \: or \: \: \: x = \frac{2 - \sqrt{10} }{3} [/tex]Step-by-step explanation:
3x² - 4x - 2 = 0
Using the quadratic formula
That's
[tex]x = \frac{ - b\pm \sqrt{ {b}^{2} - 4ac } }{2a} [/tex]From the question
a = 3 , b = - 4 , c = - 2
So we have
[tex] x = \frac{ - - 4\pm \sqrt{( { - 4})^{2} - 4(3)( - 2)} }{2(3)} \\ x = \frac{4\pm \sqrt{16 + 24} }{6} \\ x = \frac{4\pm \sqrt{40} }{6} \\ x = \frac{4\pm2 \sqrt{10} }{6} \\ x = \frac{4}{6} \pm \frac{ 2\sqrt{10} }{6} \\ x = \frac{2}{3} \pm \frac{ \sqrt{10} }{3} \\ x = \frac{2\pm \sqrt{10} }{3} [/tex]We have the final answer as
[tex]x = \frac{2 + \sqrt{10} }{3} \: \: \: or \: \: \: x = \frac{2 - \sqrt{10} }{3} [/tex]Hope this helps you

You have $135 in a savings account and save $12 per week. Your friend has $95 in a savings account and saves $20 per week. How many weeks will it take for you and your friend to have the same balance?
Answer:
It will take 5 weeks for you and your friend to have the same balance
Step-by-step explanation:
Let
Your savings expression be
135 + 12x
Your friends savings expression
95 + 20x
Where,
x = number of weeks for you and your friend to have the same balance
Equate the two expressions
135 + 12x = 95 + 20x
Collect like terms
135 - 95 = 20x - 12x
40 = 8x
Divide both sides by 8
40/8 = x
x = 40/8
= 5
x= 5 weeks
Check
Your savings expression
135 + 12x
135 + 12(5)
=135 + 60
= $195
Your friends savings expression
95 + 20x
95 + 20(5)
= 95 + 100
= $195
Therefore, It will take 5 weeks for you and your friend to have the same balance
A plane traveled 696 miles each way to New York City and back. The trip there was with the wind. It took 6 hours. The trip back was into the wind. The trip back took 12 hours. What is the speed of the wind?
A. Wind is 29 mph
B. Wind is 87 mph
C. Wind is 46 mph
D. Wind is 15 mph
Answer: A. Wind is 29 mph
Step-by-step explanation:
We can define:
Sp = speed of the plane
Sw = speed of the wind.
When the plane travels in the same direction that the wind flows, we can write the total speed as:
S = Sp + Sw
And when the plane travels against the flow of the wind, we can write:
S = Sp - Sw.
Now, we have the relation:
Distance = Speed*Time.
We know that:
Distance = 696 mi.
"The trip there was with the wind. It took 6 hours. "
then:
696mi = (Sp + Sw)*6h
"The trip back was into the wind. The trip back took 12 hours."
696mi = (Sp - Sw)*12h.
Then we have the system of equations:
696mi = (Sp + Sw)*6h
696mi = (Sp - Sw)*12h.
First, let's isolate one of the variables in one of the equations, i will isolate Sp in the first eq:
696mi/6h = Sp + Sw
116 mph - Sw = Sp.
Now we can replace this into the other equation:
696mi = (116mph - Sw - Sw)*12h
Let's solve this for Sw, that is the value that we want to find:
696mi/12h = (116mph - 2*Sw)
58mph - 116mph = -2*Sw
-58mph/-2 = Sw = 29mph.
The correct option is A.

What is the value of x? x=int(13.25 + 4/2) *
15.25 is the answer of the question
The value of x is x = int(13.25 + 4/2) is 15
Integers are negative or positive whole numbers. Given the expression for x, x=int(13.25 + 4/2)
This means that we are to express the result of x as an integer
Solving the expression 13.25 + 4/2
[tex]=13.25+\frac{4}{2} \\=13.25 + 2\\=15.25\\[/tex]
In order to convert this result into an integer, we will approximate it to the nearest whole number. Hence:
[tex]x=int(15.25)\\x \approx 15[/tex]
This shows that the value of x is x = int(13.25 + 4/2) is 15

O ABCD
0 C is the midpoint of m.
OD is the midpoint of m.
Answer:
The correct option is;
[tex]\overline{AB} \cong \overline{CD}[/tex]
Step-by-step explanation:
From the diagram, we have that the segment [tex]\overline {AB}[/tex] is given as the measured distance between the points A and B while the measured segment [tex]\overline {CD}[/tex] is constructed on the line m, starting from a point C and using a compass whose width is adjusted to the length of the segment [tex]\overline {AB}[/tex] and with the metal tip of the compass placed at C, to draw an arc the crossed the line m at a point which is then marked and labelled as then point D
Therefore the length of the segment [tex]\overline {AB}[/tex] is equal to the length of the segment [tex]\overline {CD}[/tex] and the relation is expressed as [tex]\overline{AB} \cong \overline{CD}[/tex].

2) [tex]\frac{5}{2}[/tex] = 2.5 because the 5 goes into the denominator 2 times and then you have left over .5 .
3) [tex]\frac{1}{4}[/tex] = .25 because a 1 is divided by 4.
4) [tex]\frac{1}{2}[/tex] = .5 ; a 1 is divided by 2
5) [tex]\frac{3}{4}[/tex] = .75 because you have .25 x 3 .
