Answer:
1, 210.
2. 72 minutes.
3. 42 minutes
4. 2 inches.
5. 3 cents.
Step-by-step explanation:
1. First, divide 240 by 8, which will get you 30, now multiply 30 by 7 and you will get 210 which is your answer.
2. Your keyword here is times. So you know you will multiply. So just multiply 8 and 9, and your product is 72, so 72 minutes.
3. Multiply 3 1/2 by 12, or convert your fraction to a decimal, which in decimal form is 3.50. Your product would be 42.
4. Multiply 1/7 by 14, you should get 14/7, which is an improper fraction. Divide 14 by 7 and you will get 2 inches.
5. So here you have to find the unit rate. Divide the price by the quantity.
4.86/16.2=0.297530865
Round the number up, which would be 3. So it would be 3 cents

Step-by-step explanation:
WHAT MOVIE HAS 7 THEATRICAL REALESES
Answer:
The meaning theatrical releases means the date a new movie is entered into the theater distribution system for public viewing. Alternate formats of the movie, such as DVDs, Blu-ray discs and video-on-demand, are scheduled for distribution a set number of weeks or months after the theatrical release. See video-on-demand. So if that is what it means then the movie i think that has 7 theatrical releases is the new movie "Mulan" because the people started making the movie on March 9th, 2020 and released the movie on September 4th, 2020. If i am incorrect i apologize
Hope this helps, have a great day and stay safe! :))))))))))))))

Solve mobiles plz help I’m confused
Answer:
Gold square = 4
Blue triangle = 3
Step-by-step explanation:
Red hexagon = 6, and there are 4 red hexagons. So the total is 24.
Therefore, the total on the other side must also be 24.
That means the 4 blue triangles add up to 12, and the 3 gold squares add up to 12.
So each blue triangle is 3, and each gold square is 4.

What are the solutions of x^2-2x+5=0? A. X=2i or x=-2i. B. X=1+2i or x=1-2i. C. X=2+i or x=2-i. D. X=2+2i or x=2-2i
Answer:
B. x=1+2i or x=1-2i.
Step-by-step explanation:
The equation is given as;
x²-2x+5=0
complete the square method to find value of x as;
x²-2x = -5
x²-2x + 1 = -5 + 1
x²-2x +1 =-4
( x-1 )² = -4
x-1 = ±√-4 ---------where √-1 = i
x-1 =± 2i
So;
x-1 = + 2i
x= 1+2i
or
x= 1-2i
x= 1-2i
Tom needs 9/10 pints of glue for his art project. He has 7/10 pints of glue. How much more glue does he need? write in simplest form.
Answer:
7/10-5/10= 2/10≈ 1/5
Step-by-step explanation:
hope this is right and i hoped this helped
Answer:
1/5 pint
Step-by-step explanation:
given:
Amount of Glue needed = 9/10 pints
Amount of Glue available = 7/10 pints
Amount of extra glue needed = Amount of glue needed - Amount of Glue Available
= 9/10 - 7/10
= (9-7)/10
= 2/10 (simplify by dividing both numerator and denominator by 2)
= 1/5 pint

(DOES NOT BELONG) Is Rational
(DOES NOT BELONG) Is not Irrational
(DOES NOT BELONG) Is not an integer
(DOES NOT BELONG) Not a Whole
(DOES NOT BELONG) Not Natural
Step-by-step explanation:
This is a fraction with a square root.
Fractions:
Are Not Whole (square root cancels this)
Are Rational BUT since this has a square root, it is not.
Are not natural
Are not integers (Whole numbers that ARE NOT fractions)
So basically from what I have learned, square root cancels literally everything.
What value of x makes this equation true? 2(4x-3) - 8= 4+2x
Answer:
What value of x makes this equation true? 2(4x-3) - 8= 4+2x HERE YOU GO!!
Step-by-step explanation:
We need to eliminate one of the variables to solve the other.
4x+5y = 8
2x-3y = 18
I will multiply the second equation by -2.
-2*(2x-3y = 18)
-4x + 6y = -36 and then add the two equations
4x + 5y = 8
-4x + 6y = -36
+ adding here
11y = -24
y = -24/11
substitute x in one of the equations to find y.
2x-3y=18
2x - (3*-24/11) = 18
2x = 126/11
x = 126/22

Miguel has $30. He spends $6.75 on a movie ticket, $3.65 for snacks, and $2.00 for bus fare each way.
How much money does Miguel have left? please help :}
Answer:
$15.60
Step-by-step explanation:
We can solve this problem easily by adding up Miguel's expenses, and then subtracting them from the amount he started with. Be careful, as he pays $4, not $2, in total for bus fare, because he is paying $2 to and from:
[tex]6.75+3.65+4.00[/tex]
[tex]=14.40[/tex]
Let's subtract our sum, [tex]14.40[/tex], from our total, [tex]30[/tex]:
[tex]30-14.40[/tex]
[tex]=15.60[/tex]
Miguel has $15.60 left.

Answer:
25/784
Step-by-step explanation:
In efforts of improving their orofit margins, a company is considering creating their own manufacturing plant for their product. It had a start-up cost of 25,000 to build the plant. This plant will drop the production cost down to $15 per item. If each item sells for $50, then how many items would it take to get an overall profit of $100,000 for the year?
Answer:
To get an overall profit of $100,000, then 3,571 items is needed to be produced
Step-by-step explanation:
Mathematically;
Profit = Revenue - Production cost
In the question, we are told that the profit we are expecting is $100,000
Let the number of items to be produced for sales be x items
Now let’s look at the production cost ;
The production cost will be number of items for sale * production cost = 15 * x = $15x
Now, we need to add the start-up cost to the production cost to get the total amount spent on production;
Mathematically the total amount would be = $25,000 + $15x
Let’s look at the revenue;
The revenue will be selling price of each item * price of each item;
Mathematically, that would be 50 * x = $50x
So therefore;
50x - (25,000 + 15x) = 100,000
50x -25,000 -15x = 100,000
35x = 100,000 + 25,000
35x = 125,000
x = 125,000/35 = 3571.42 which is approximately 3,571 items
What is the value of x?
Answer:
10
Step-by-step explanation:
5x - 17 = 3x + 3 (vertically opposite angles)
5x - 3x = 3 + 17
2x = 20
x = 20/2
x = 10
