The time at which the buses will leave at the same time is 8:40 am.
What is a factor?A factor is a number that divides another number, leaving no remainder
Example: 3 x 2 = 6
2 is a factor of 3.
We have,
Buses:
X leaves every 25 minutes.
Y leaves every 20 minutes.
We need to find the least common multiples of 25 and 20.
25 x 4 = 100
20 x 5 = 100
100 is our least common multiple of 25 and 20.
We see that,
4 is a factor of 24 which gives 100.
This means after 4 times, bus X will leave with bus Y at the same time.
5 is a factor of 20 which gives 100.
This means after 5 times, bus Y will leave with bus X at the same time.
The first buses to X and Y leave a bus station at 7 am.
After 100 minutes, buses X and Y will leave at the same time.
= 7am + 100 minutes
= 7 + 60 minutes + 40 minutes
= 7 + 1 hour + 40 minutes
= 8:40 am
Thus,
The time at which the buses will leave at the same time is 8:40 am.

What is the area of a rectangle?Area of a rectangle is the product of the length of the rectangle and the width of the rectangle. It can be given as,
[tex]A=a\times b[/tex]
Here, (a)is the length of the rectangle and (b) is the width of the rectangle
The length of the rectangle is 15 cm and width is 8 cm. Thus, the area of it is,

Step-by-step explanation:
it's actually quite simple. if the angles add up to 180°, it is a triangle. so if they don't, then its not a triangle.
21+28+41= 90 -> not a triangle
65+45+70=180 -> triangle
48+52+54=154 -> not a triangle

In a recent poll among 500 students, it was found that 60% of women and 68% of men eat meals on campus at least 3 times a week. What type of statistical test would you use to see whether men and women differ in the extent to which they eat meals on campus at least three times a week
The statistical test would be a Z-test for the difference between the proportions.
What is Z-test?The Z test is a parametric procedure that is used on data that is dispersed in a normal fashion. For testing hypotheses, the z test can be used on one sample, two samples, or proportions. When the population variance is known, it analyzes if the means of two big groups are dissimilar.

Answer:
s = 132 square cm
Step-by-step explanation:
s = area of base + area of lateral faces
Area of base (triangle)
A = 1/2bh
A = 1/2(3)(4)
A = 1/2(12)
A = 6
There are two bases (triangles), so multiply the answer by 2.
6 x 2 = 12
Area of lateral faces (3 rectangles)
First rectangle:
A = lw
A = 5(10)
A = 50
Second rectangle:
A = lw
A = 4(10)
A = 40
Third rectangle:
A = lw
A = 3(10)
A = 30
Add all the areas together.
s = 12 + 30 + 40 + 50
s = 132 square cm
PLEASE HELP GIVING BRAINLIST!!! Given ΔXYZ is isosceles, what is XZ if the perimeter is 107 units and XZ = 1/2 XY?
And XZ=1/2XY
XZ be x
XY=YZ=2xNow
x+2x+2x=1075x=107x=21.4unitsXZ=21.4units
Answer:
XZ = 21.4 units
Step-by-step explanation:
If ΔXYZ is an isosceles triangle then XY = ZY
(the dashes on the line segments indicate they are of equal measure)
If XZ = ¹/₂XY then
⇒ 2XZ = XY = ZY
If the perimeter is 107 units:
⇒ Perimeter of ΔXYZ = XY + ZY + XZ
⇒ 107 = 2XZ + 2XZ + XZ
⇒ 107 = 5XZ
⇒ XZ = 107 ÷ 5
⇒ XZ = 21.4 units

Which equation could be solved using this application of the quadratic formula? a. -2x2 − 8 = 10x − 3 b. 3x2 − 8x − 10 = 4 c. 3x2 8x − 10 = -8 d. -2x2 8x − 3 = 4
The equation that can be solved when the given quadratic formula is used is c. 3x² + 8x − 10 = -8.
How can we use quadratic equations?The given quadratic equation is:
x = (-8 ± √(8² - 4(3)(-2))) / 2 (3)
Rewriting the quadratic equation in option C gives:
3x² + 8x − 2 = 0
Seeing as a quadratic equation takes the form:
x = (-b ± √(b² - 4(a)(c))) / 2 (a)
The formula becomes:
x = (-8 ± √(8² - 4(3)(-2))) / 2 (3) which is the given quadratic formula.
In conclusion, option C is correct.

help me pls, will mark brainliest!!!!!!!!!!!!!
Step-by-step explanation:
since he was already on time on the first day, the question is reduced to the probability of being on time on exactly one of the next 2 days.
the probability to be on time on exactly one day means to be on time on one day and to be late on the other.
the probability to be late is the opposite of the probability to be on time, so
1 - 0.7 = 0.3
so, the probability for this combined event for one of the day combinations is
0.7 × 0.3 = 0.21
how many day combinations (1 day on time, the other late) can we have ? 2 (either on time on the first and late on the second, or late on the first and on time on the second).
so, we need to multiply this with the basic probability and get
0.21 × 2 = 0.42
so, b. is the right answer.

What is the congruence theorem?Triangle congruence theorem or triangle congruence criteria help in proving if a triangle is congruent or not. The word congruent means exactly equal in shape and size no matter if we turn it, flip it or rotate it.
Consider ΔABC and ΔDEF,
Here, ∠B=∠E=50°
AB=DE=10 units
With ∠C=∠F
So, by AAS congruence theorem ΔABC and ΔDEF are congruent

In Lin's drawing, the scale is 5 inches = 8 feet, and the back wall of the lab measures
15 inches. Five computer workstations will be equally spaced along the entire
length of that wall. Each workstation measures 4 feet by 4 feet. How far apart are
the workstations in Lin's drawing? Explain.
Answer:
1 ft
Step-by-step explanation:
scale: 5 in. = 8 ft
Back wall scale measurement: 15 in.
Back wall real measurement: 15 in. × 8 ft / 5 in. = 24 ft
Each workstation measures 4 ft.
5 workstations measure 5 × 4 ft = 20 ft
24 ft - 20 ft = 4 ft
When you place 5 workstations, the outer two will be at the ends of the 24-ft wall. There will be 4 spaces between the workstations.
4 ft / 4 = 1 ft
Answer: 1 ft

What are the trigonometric ratios?Trigonometric ratios are the ratio of sides of a right angled triangle. There are 6 types of trigonometric ratios: sin, cos, tan, cosec, sec, and cot.
Sine trigonometric ratio is the ratio of perpendicular (side opposite to the angle) to the hypotenuse.
In the given figure, the side opposite to the angle [tex]\beta[/tex] is AC = 4 and the hypotenuse is AB = 5.
So, the sine ratio will be equal to,
