Answer:
10:30 hours
Step-by-step explanation:
Total distance=300 Miles, Start Time=07:15
Distance travelled so far is 125 miles for 2.5 hours
First we need to calculate Ayoub's speed as follows
Speed=Distance/Time
=125miles/2.5hour
=50 miles/hr
The calculate the remaining distance
=300-125
=175 Miles
Assuming that Ayoub Travels in the same speed at the first 300 miles, the time he will use to cover the remaining 175 miles is
Time=Distance/speed
Substituting the values
Time=175/50
=3.5 hours
The time he will arrive at Paris is
07:15+03:30
=10:30 hours

Question 2
First calculate the time taken to travel from woodpine to Westray
Time=Distance/ Speed
=32.5/65
=0.5 hours or 30 minutes
Next we calculate the average speed
Average speed is calculated by taking the total distance divided by total time taken
Total distance =32.5+100
=132.5KM
Total time=2+0.5
Average speed=132.5/2.5
=53km/

Step-by-step explanation:
Conversion a mixed number 10 2/
3
to a improper fraction: 10 2/3 = 10 2/
3
= 10 · 3 + 2/
3
= 30 + 2/
3
= 32/
3
To find new numerator:
a) Multiply the whole number 10 by the denominator 3. Whole number 10 equally 10 * 3/
3
= 30/
3
b) Add the answer from previous step 30 to the numerator 2. New numerator is 30 + 2 = 32
c) Write a previous answer (new numerator 32) over the denominator 3.
Ten and two thirds is thirty-two thirds
Conversion a mixed number 9 11/
12
to a improper fraction: 9 11/12 = 9 11/
12
= 9 · 12 + 11/
12
= 108 + 11/
12
= 119/
12
To find new numerator:
a) Multiply the whole number 9 by the denominator 12. Whole number 9 equally 9 * 12/
12
= 108/
12
b) Add the answer from previous step 108 to the numerator 11. New numerator is 108 + 11 = 119
c) Write a previous answer (new numerator 119) over the denominator 12.
Nine and eleven twelfths is one hundred nineteen twelfths
Add: 32/
3

12
= 128/
12

For adding, subtracting, and comparing fractions, it is suitable to adjust both fractions to a common (equal, identical) denominator. The common denominator you can calculate as the least common multiple of both denominators - LCM(3, 12) = 12. In practice, it is enough to find the common denominator (not necessarily the lowest) by multiplying the denominators: 3 × 12 = 36. In the next intermediate step, the fraction result cannot be further simplified by canceling.
In words - thirty-two thirds plus one hundred nineteen twelfths = two hundred forty-seven twelfths.
What is -2 1/6 -(-1 3/4)
Answer:
-5/12
Step-by-step explanation:
2 1/6 -(-1 3/4) =
-13/6 - (-7/4) =
-5/12
-5/12
Step-by-step explanation:
Step 1: Eliminating a negative and changing our operation
−2 1/6 + 1 3/4
Step 2: Rewriting our equation with parts separated
-2 − 1/6 + 1 + 3/4
Step 3: Solving the whole number parts
−2 + 1 = −1
Step 4: Solving the fraction parts
−1/6 + 3/4 = ?
Step 5: Find the LCD of 1/6 and 3/4 and rewrite to solve with the equivalent fractions.
LCD = 12
−2/12 + 9/12 = 7/12
Step 6: Combining the whole and fraction parts
−1 + 7/12 = −5/12

Answer:
The area of each figure is:
Area of the rectangle = 10 square units.Area of the triangle = 10 square units.Area of the figure = 20 square units.Step-by-step explanation:
To find the area of that figure, first, we're gonna find the area of the rectangle and next the area of the triangle, to make this we need to identify the measurement of each one, the rectangle has 2 units wide and 5 units high, then, we use the next formula:
Area of a rectangle = width * heightArea of a rectangle = 2 units * 5 unitsArea of a rectangle = 10 square unitsNow, we identify the measurements of the triangle (base = 4 units, height = 5 units) and we use the formula:
Area of a triangle = (base * height) / 2Area of a triangle = (4 units * 5 units) / 2Area of a triangle = (20 square units / 2Area of a triangle = 10 square unitsAnd we obtain the area of the whole figure when we add the two areas:
Area of the figure = area of the triangle + area of the rectangleArea of the figure = 10 square units + 10 square unitsArea of the figure = 20 square units.As you can see, the area of the picture is 20 square units.

Find the area and circumference of the circle. Round any answer to the nearest hundredth. Please include the unit of measure in your answer.
Answer:
A=326.85 in² , C=64.09 in
Step-by-step explanation:
Area of a circle= πr²
r=10.2 in
Plug into a calculator
A=π(10.2 in)² = 326.85129....≈326.85 in²
Circumference = 2πr
C=2π(10.2) = 64.08849...≈64.09 in

Answer:
4th
Step-by-step explanation:
string length is 0.5m and the wavelengths are 0.25meters. This tells us there are two complete waves in the guitar string. This gives us a total of four antinodes; thus we are in the fourth harmonic.
Hi guys it's nothing much but please help me out for braniest and 50 points NO LINK'S thank you
Answer:
Step-by-step explanation:
1) A similar triangle must have the same ratios of sides. Triangle ABC and triangle LNM are similar because all the sides of LNM are 1/2 of the sides of ABC. As they are all in a 1:2 ratio, the triangles are similar.
2) ADE and ABC are similar because each angle is the same. Angle D and Angle B are the same because they are shown as the same with the same dot symbolization. Angle E and C are the same because they are shown as the same with the same curvy angle representation. ADE and ABC share A as the same angle, so all three angles are the same.
5) As triangles ABC and EDC are similar, the sides must have the same ratio. ED is similar to AB, EC is similar to AC, and CD and BC are similar. First we find the ratio. The only pair of similar lines are EC and AC, so we have to find the ratio from those two lines. EC is 15 and AC is 10/3, so we do 15 divided by 10/3 and we get 9/2. Therefore, the ratio is 9/2. Now we can find x and y. We can first look at ED and AB. Ed is 12 and AB is y. We know that it must have the same ratio of 9/2, so 12/y must equal 9/2. We can do proportions. 12/y = 9/2, 9y = 24 (you multiply the numbers diagonally). So, we get y = 8/3. Now we can get x the same way. BC and CD are similar, and so x/5 must equal 9/2 as well. We use proportions again and we have x/5 = 9/2, so 45 = 2x and x = 45/2.
Answer:
4.ADE /// ABC (same <s)
<D = <B (corresponding <s)
<E = <C (corresponding <s)
ADE and ABC share A as the same < so all <s are = (AAA )

Step-by-step explanation:
An angle measures 58° less than the measure of a complementary angle. What is the measure of each angle?
Answer: 74 degrees and 16 degrees
Step-by-step explanation:
A pair of complementary angles add up to 90 degrees.
If we know that one of the two angles is 58 degrees less than the other, we can solve the algebraic equation: x + (x-58) = 90, where (x) is the measure of the one angle, and (x-58) is the measure of the other angle.
x + x-58 = 90 is the same as 2x -58 = 90.
Adding 58 to both sides gives 2x = 148,
and dividing both sides by two gives x = 74.
We now know that one angle is 74 degrees, and the other angle is (74-58) degrees. This gives two angles of 74 and 16 degrees. They both add up to 90 degrees, so they are complementary angles.

Separate your answers with a comma.
Answer:
[tex]L = 704[/tex]
[tex]S = 832[/tex]
Step-by-step explanation:
Given
[tex]H = 22[/tex] --- Height
[tex]W = 8[/tex] --- Width
[tex]L=8[/tex] ---- Length
Solving (a): The lateral surface area (L)
This is calculated as:
[tex]L = 2 * (L + W) * H[/tex]
This gives:
[tex]L = 2 * (8 + 8) * 22[/tex]
[tex]L = 2 * 16 * 22[/tex]
[tex]L = 704[/tex]
Solving (b): The total surface area (T)
This is calculated as:
[tex]S = 2 * (LW + WH + LH)[/tex]
This gives:
[tex]S = 2 * (8*8 + 8*22+ 8*22)[/tex]
[tex]S = 2 * (64 + 176+ 176)[/tex]
[tex]S = 2 * 416[/tex]
[tex]S = 832[/tex]

Help for Brainlyiest plsss
Answer:
n = 4
Step-by-step explanation:
The expression must equal 6. Thus, we can make an equation:
3n - (2 + n) = 6
We distribute the negative and take away the parenthesis:
3n - 2 - n = 6
We combine like terms:
2n - 2 = 6
We add 2 to both sides to isolate n:
2n = 8
We divide each side by 2:
n = 4.

The angle of depression of a point G on a horizontal ground from top T of an electrical pole is 25°. If the distance from G to the foot of the pole is 45m, calculate the height of the pole to the nearest whole number. PS: use scale 1:9.
Answer: 21 m
Step-by-step explanation:
Given
the angle of depression of point G is [tex]25^{\circ}[/tex]
Distance from pole base to point G is 45 m
Suppose h is the height of the pole
From the figure, we can write
[tex]\Rightarrow \tan 25^{\circ}=\dfrac{h}{45}\\\\\Rightarrow h=45\tan 25^{\circ}\\\Rightarrow h=20.98\approx 21\ m[/tex]
