Colin types his research paper for 3 hours. how many minutes is that?
Answer:
180 minutes
Step-by-step explanation:
60*3=180
Hey there! The answer is:
180 minutes
Explanation:
There are 60 minutes in 1 hour. We know Colin typed his research paper for 3 hours. This means we can multiply 60 minutes by 3 hours and that will give us the number of minutes he spent researching his paper.
60 x 3 = 180
This means Colin typed his research paper for 180 minutes. I hope this answer helped you out, have an amazing day :)

Answer:
a = [tex]\frac{34}{4}[/tex]
x = 19
Step-by-step explanation:
First equation
Expand the brackets
4(a-3) = 22
4a - 12 = 22
Add 12 to both sides
4a - 12 + 12 = 22 + 12
4a = 34
Divide both sides by 4
4a ÷ 4 = [tex]\frac{34}{4}[/tex]
a = [tex]\frac{34}{4}[/tex]
Second equation
Expand the brackets
5(x - 6) = 65
5x - 30 = 65
Add 30 to both sides
5x - 30 + 30 = 65 + 30
5x = 95
Divide both sides by 5:
5x ÷ 5 = 95 ÷ 5
x = 19
Hope this helps!

Mr. Ross washed
1/4
of his laundry. His son washed
2/5
of it. Who washed most of the laundry? How much of the laundry still needs to be washed?
Answer:
the son. and 7/20
Step-by-step explanation:
you would ave the denominator to make them both 20 then the fractions would become 5/20 and 8/20 so it would be the son who washed the most. then add them together and get 13/20 so 7/20 laundry needs to be done

A girl starts from Point A and walks to 285m to B on a bearing of 078°. She then walks due south to a point C which is 307m from A. What is the bearing of A from C and what is IBCI
Answer:
bearing of A from C is - 65.24°
the distance |BC| is 187.84 m
Step-by-step explanation:
given data
girl walks AB = 285 m (side c)
bearing angle B = 78°
girl walks AC = 307 m (side a)
solution
we use here the Cosine Law for getting side b that is
ac² = ab² + bc² - 2 × ab × cos(B) ...............1
307² = 285² + x² - 2 × 285 cos(78)
x = 187.84 m
and
now we get here angle θ , the bearing from A to C get by law of sines
sin (θ) =
sin (θ) = 0.5985
θ = 36.76°
and as we get here angle BAC that is
angle BCA = 180 - ( 36.76° + 78° )
angle BCA = 65.24°
and here negative bearing of A from C so - 65.24°

Find the area of the following kite:
Answer:
[tex]48 cm^2[/tex]
Step-by-step explanation:
Each of the small triangles are right, so we can add up all the small triangle's areas to find the total area.
The 4-by-10 triangle: The area is [tex]4*10/2=40/2=20[/tex].
The other 4-by-10 triangle has the same side lengths and hence the same area, so the area is [tex]20[/tex].
The 4-by-4 triangle: The area is [tex]4*4/2=8/2=4[/tex].
The other 4-by-4 triangle has the same area, [tex]4[/tex].
The total area is [tex]20+20+4+4=\boxed{48} cm^2[/tex].
In the following diagram lines m are n parallel the measures of AEB, BAE and CED are shown what is the measure of EBF
Answer:
∠ EBF = 98°
Step-by-step explanation:
(3x - 15) and (2x + 10) are vertically opposite angles and are congruent, then
3x - 15 = 2x + 10 ( subtract 2x from both sides )
x - 15 = 10 ( add 15 to both sides )
x = 25
3x - 15 = 3(25) - 15 = 75 - 15 = 60°
The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
∠ EBF is an exterior angle of the triangle , then
∠ EBF = 60° + 38° = 98°

-7 + 8x2 - 4x
Answer: 8x^2 -4x -7
Step-by-step explanation: the x^2 term comes first, followed by the x, then the constant which in this case is -7
so it would be 8x^2 -4x -7
The polynomial -7 + 8x² - 4x written in descending order is 8x² - 4x - 7.
To write the polynomial -7 + 8x² - 4x in descending order, we arrange the terms from highest degree to lowest degree.
Here's how to do it step by step:
Step 1: Identify the degree of each term:
The term -7 has a degree of 0 (since it is a constant).
The term 8x² has a degree of 2 (since it has a variable raised to the power of 2).
The term -4x has a degree of 1 (since it has a variable raised to the power of 1).
Step 2: Arrange the terms in descending order based on their degrees:
Start with the term with the highest degree and proceed in decreasing order. In this case, we have only three terms, so we start with the highest degree term:
8x² (degree 2)
Next, we consider the next highest degree term:
-4x (degree 1)
Finally, we have the constant term:
-7 (degree 0)
Step 3: Write the polynomial in descending order:
Putting the terms together in descending order, we have:
8x² - 4x - 7
So, the polynomial -7 + 8x² - 4x written in descending order is 8x² - 4x - 7.

Answer:
36/40 or 90%
Step-by-step explanation:
First convert it to a fraction, which in this case is 36/40.
To find the percentage, we need to find an equivalent fraction with the denominator of 100. Multiply both numerator & denominator by 100.
36/40 × 100/100
= (36 × 100/40) × 1/100 = 90/100
Therefore, the answer is 90%.
If you are using a calculator, simply enter 36÷40×100, which will give you 90 as the percentage.

help me find x in this triangle
Answer:
x=176 degrees
Step-by-step explanation:
The first step to solving this is filling out any information we have. We know a solid line is 180 degrees, so the angle next to 92 must be 88.
We also know that the length of the line dividing 92 and 88 is equal to the other line with a small line in the middle. Because of this, the angle above the first 88 we found is also 88 degrees.
Now that we know two of the angles in the triangle add up to 176, we can figure out that the other angle is equal to 4. We know this because the sum of the interior angles of a triangle must equal 180.
This may seem off to you, but keep in mind that this diagram is likely not to scale.
Using the same rule we used for the first part we did, we can deduce that x equals 176.

suppose river has new treats that are 10 calories each. how many of the new treats can she have and remain in her calorie range?
She can have at least 3 and at most 6 dog treats in a day
River can have - n = 10/y number of treats to remain in her calorie range, where the calorie range is [y] calories.
What is the general equation of a Straight line?The general equation of a straight line is -
[y] = [m]x + [c]
where -
[m] is slope of line which tells the unit rate of change of [y] with respect to [x].
[c] is the y - intercept i.e. the point where the graph cuts the [y] axis.
The equation of a straight line can be also written as -
Ax + By + C = 0
By = - Ax - C
y = (- A/B)x - (C/A)
We have the following problem -
River has new treats that are 10 calories each. how many of the new treats can she have and remain in her calorie range.
Assume the calorie range to be [y] calories and assume she can have [n] number of treats. We can write the linear function as -
10n = y
OR
y = 10n
This this the equation of the straight line. She can have -
n = 10/y
number of treats to remain in her calorie range.
Therefore, River can have - n = 10/y number of treats to remain in her calorie range.
