Given:
The length of each ribbon is 25 cm.
The number of ribbon need by mother is 6.
Explanation:
Determine the length of ribbon for daughter's hair.
[tex]\begin{gathered} 25\cdot6=150\text{ cm} \\ =1.5\text{ m} \end{gathered}[/tex]Since length is in decimal so we need to find multiple of 25 such that it is more than 150 and multiple of 100.
The multiples of 25 are 25,50, 75, 100, 125, 150, 175, 200, ...
Since 200 is more than 150 and multiple of 100 also.
Determine the length of 200 cm in terms of meters.
[tex]200\text{ cm}\cdot\frac{1\text{ m}}{100\text{ cm}}=2\text{ m}[/tex]So mother needs to buy 2 meters of ribbon.
Answer: 2 meters
A car loan totaling 13,456.44 paid off in 36 equal monthly payment can afford no more than $350 per month can she or down explain
She cannot afford to buy the car with monthly instalments of $350. She needs to make a downpayment of $856.44 to afford the car
The total amount of the car loan = 13456.44
Number of instalments = 36 monthly payments
Affordable installment per month = $350
EMI: A fixed payment is made by a borrower to a lender at a specific time each month, known as an equated monthly instalment (EMI). The loan is repaid in full over a predetermined period of time by making equal monthly payments to the principal and interest.
Total payment that can be made using the instalments = Monthly instalments * Number of instalments
= 350*36
Total payment that can be made using the instalments = 12600
The amount remaining after paying instalments = 13456.44 - 12600
= 856.44
Downpayment required = $856.44

The tanker has been filling the reservoir for 0.0288 minutes or 1.728 seconds as the rate of filling is 1212 gallons per minute using the estimation concept.
As per the question statement, A tanker truck fills the gas station’s reservoir at the rate of 1212 gallons per minute and the reservoir was empty and it is now 35 gallons full. We are supposed to find out for how long has the tanker been filling the reservoir. We will use the concept of estimation.
Rate of filling gas = 1212 gallons per minute
i.e., 1212 gallon of gas taken 1 minute for transfer.
1 gallon of gas will take = (1/1212) minutes
Hence 35 gallons of gas will take = (1/1212)*35 minutes = 0.0288 min.
So, the tanker has been filling the reservoir for 0.0288 minutes or 1.728 seconds as the rate of filling is 1212 gallons per minute.

1,936 divided by 8 in long division
Answer:
242.
Step-by-step explanation:
Basically, you have to put the 2 numbers "1936" and "8" down. After you put the 2 numbers down, you have to figure out how many times 8 goes into 19 which is 2 times.
You put the 2 above the 1 in 1936. After you put the 2 up there, you have to figure out 2 x 8 which is 16. You have to put the 16 below the 19 and subtract 19 by 16 which is 3.
After you finish that equation, you must bring the 3 down next to the 3 you wrote down on 19 - 16. The number turns into 33 and you have to figure out how many times 8 goes into 33 which is 4 times. You put the 4 next to the 2 above and then do 4 x 8 which is 32. You do 33 - 32 which is 1.
You bring the 6 down in 1936. It turns into a 16. You now have to figure out how many times 8 goes into 16 which is 2 times. You put 2 next to the 2 and the 4 above and that turns the number into 242.
You then have to do 2 x 8 which is 16 and put 16 under the 16 from 33 - 32. That'll make an equation which is 16 - 16 which is 0. There is no remainder and all the numbers were added above so 242 is your answer.

Find sin(2x), cos(2x), and tan(2x) from the given information.
tan(x) = − 4/3 , x in Quadrant II
Answer:
Step-by-step explanation:
Starting from tan x, you can find sec x, because of the trigonometric identity 1 + tan2 x = sec2 x.
1 + (-4/3)2 = 1 + 16/9 = 25/9 = sec2 x.
So sec x = ±√(25/9) = ±5/3. But since x is in Quadrant II, sec x has to be negative. That's because sec x has the same sign as cos x, because sec x = 1 / cos x. We know that cos x is negative is Quadrant II, therefore so is sec x. So sec x = -5/3.
Since sec x and cos x are reciprocals of each other, cos x = 1/sec x = -3/5.
Now use the identity sin2 x + cos2 x = 1, to find sin x:
sin2 x + (-3/5)2 = 1
sin2 x + 9/25 = 1
sin2 x = 16/25
sin x = ±4/5
Again, we know that sin x is positive in Quadrant II, so sin x = 4/5.
Now that we know sin x and cos x, we can use the double angle formulas to find sin 2x and cos 2x.
sin 2x = 2 sin x cos x = 2 (4/5) (-3/5) = -24/25
cos 2x = cos2 x - sin 2 x = (-3/5)2 - (4/5)2 = 9/25 - 16/25 = -7/25
Finally use the identity tan x = sin x / cos x to find tan 2x:
tan 2x = sin 2x / cos 2x = (-24/25) / (-7/25) = -24/-7 = 24/7

A triangle, ABC, has angle measures of 45°, 45°, and 90° and two congruent (equal) sides. How would this triangle be classified?
O Isosceles acute
O Scalene acute
O Scalene right
O Isosceles right
Answer:
(d) Isosceles right
Step-by-step explanation:
You want to know the classification of a triangle with angles 45°-45°-90°.
ClassificationThe largest angle is 90°, a right angle. Any triangle containing a right angle is a right triangle.
Two of the angles have the same measure. This means the triangle is an isosceles triangle.
The triangle is classified as an isosceles right triangle.
__
Additional comment
A triangle whose largest angle is less than 90° is an acute triangle. If the largest angle is greater than 90°, it is an obtuse triangle.
If no sides are the same length, the triangle is scalene. If two sides are the same length, the triangle is isosceles. If all three sides are the same length, it is an equilateral triangle.
Larger angles are opposite longer sides, so if angles are the same, their opposite sides are the same.
It can be worthwhile to remember that the side length ratios in an isosceles right triangle are 1 : 1 : √2.

The pattern extends forever in all directions. A give all angles of rotational symmetry between 0 and 360 degrees about the two marked points. point A: Point B:
EXPLANATION
Let's see the facts:
The angles of symmetry in point A is 60 degrees because the plane in point A is divided in 6 parts, so dividing 360° by 6 give us 60°. The same reasoning applies for the point B dividing it by 3 parts.
The angles of symmetry in point B is 120 degrees.
A wireless company offers two cell phone plans. For the month of September Plan A charges $35 plus $0.25 per minute for calls. Plan B charges$20 plus $0.50 per minute for calls. ?
EXPLANATION
Let's see the facts:
Plan A --> $35 + $0.25/minute
Plan B --> $20 + $0.5/minute
Let's call "x" to the number of minutes that a person could talk.
Here we have two equations as follows:
(1) 35 + 0.25x
(2) 20 + 0.5x
Where x represents the number of minutes a person talks on the phone.
We need to equal both equations in order to obtain the same cost.
35 + 0.25x = 20 + 0.5x
Now, we need to solve this equality as shown as follows:
-Subtracting -35 to both sides:
35 + 0.25x -35 = 20 + 0.5x -35
-Adding similar terms:
0.25x = 0.5x - 15
-Subtracting -0.5x to both sides:
0.25x - 0.5x = -15
-Adding similar terms:
-0.25x = -15
-Dividing both sides by -0.25:
x = -15/-0.25
-Simplifying:
x= 60 minutes
So, when a person talks for 60 minutes the cost of both plans is the same.
