Answer: 10:58 a.m.
Step-by-step explanation:
To solve this problem, find how many hours will pass in the given timeframe. From this Monday to next Monday, a week will pass. A week is equal to 7 days. A day has 24 hours, so multiply 7 days by 24 hours. 7*24 = 168 hours.
Since the watch gains 10 seconds every hour, multiply 168 hours by 10 seconds. This means your watch will gain 1680 seconds over the week.
To find what time the watch will be at, first find how many minutes will pass. There are 60 seconds in a minute, so divide 1680 seconds by 60 seconds. 1680/60 = 28.
Add 28 minutes to 10:30 a.m. to get a final time of 10:58 a.m.
Dog in a Ditch
Oscar and Rasheed are identical twins. They are both 6 feet tall. They are on opposite sides of
a ditch that is 30 feet wide. Their dog, Earl, is at the bottom of the ditch and is walking away
from Oscar towards Rasheed. Earl can get out if he wants to. When Oscar looks at Earl, his line
of sight makes a 75° angle below the horizontal. When Rasheed looks at Earl, his line of sight
makes a 40° angle below horizontal. Earl has walked % of the way across the ditch. How deep
is the ditch?
The ditch is 14.54 feet deep.
What is application of Trigonometry?Trigonometry can be used to roof a house, to make the roof inclined ( in the case of single individual bungalows) and the height of the roof in buildings etc. It is used naval and aviation industries. It is used in cartography (creation of maps). Also trigonometry has its applications in satellite systems.
As, both brother have height of 6 feet.
We will use the concept of application of trigonometry to find the depth of ditch.
The explanation is attached below
Now, by solving both equations we get
0.8391y= (2+√3)(30-y)
4.5711y=111.96
y= 24.49 feet.
Now,
x= 14.54 feet.
Hence, the depth of ditch is 14.54 feet.

Find the total surface area of a cylinder with a height of 7 cm and radius of 3 cm. leave your answer in terms of π.
Answer:
60π
Step-by-step explanation:
Formula for surface area of a cylinder is 2πrh + 2r²π
2πrh: this is the formula to find the area of the cylinder itself (circumference of the base times the height of the cylinder)
2r²π: this is the formula to find the area of the 2 circles at the end of the cylinder (area of a circle times 2)
We can substitute h with 7 and r with 3 to solve:
2πrh + 2r²π
2(3)(7)π + 2π(3²)
42π + 18π

Area of triangle = 24
Answer:
[tex]x=-2\pm2\sqrt13[/tex]
Step-by-step explanation:
The area of the triangle is;

The Ratio of boys to girls at Verrado Middle School is 4 to 5. If there are 300 boys at VMS, how many more girls are
there than boys?
(Someone pls help :>)
Answer:
75 more girls.
Explanation:-
Given:- Ratio of girls to boys = 5:3
And, the number of boys= 300
Let boys be 4x and girls be 5x
So, 4x = 300 (Given)
x = 300/4 = 75
Thus number of girls:- 5x = 5×75= 375 girls
now you take the 375 girls minus the 300 boys.
375-300 = 75 Girls more

Answer:
No, corresponding angles aren't congruentStep-by-step explanation:
We have a transversal and lines intersecting with it.
The angle measures formed by the lines and the transversal are not all equal to each other.
Four of the angles measure 85° and one 79°.
These are corresponding angles (the angles which occupy the same relative position at each intersection where a straight line, transversal, crosses two or more others).
If corresponding angles are equal, the lines are parallel.
In our case all the lines intersecting the transversal are parallel apart from the one with different angle measure.
Therefore, correct answer choice is:

Step-by-step explanation:
The scalene triangle is a type of triangle with sides of three different lengths and angles of three different measurements. In every scalene triangle, the shortest side is opposite the smallest angle and the longest side is opposite the largest angle.

Spencer is draining his swimming pool. The expression - 720x + 4,000 represents the amount of water, in gallons, remaining in the pool
after x hours. What does 4,000 represent?
A the time left until the pool is empty
B the gallons of water initially in the pool
Cthe total hours required to drain the pool
D the amount of water being drained per hour
Using linear function concepts, it is found that the representation of the value of 4,000 is given by:
B the gallons of water initially in the pool.
What is a linear function?A linear function is modeled by:
y = mx + b
In which:
m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.In this problem, the amount of water in the pool after x hours is modeled by:
y = -720 x + 4000.
4000 is the y-intercept, which is the initial amount of water in the pool, hence option B is correct.

The area of a rectangle is 49d + 91
The length is an integer higher than 1, but is a known number.
Find the width of the rectangle.
Assuming that L and d are known numbers, we can write.
[tex]W = \frac{49d + 91}{L}[/tex]
How to get the width of the rectangle?
Remember that for a rectangle of width W and length L, the area is given by:
A = L*W
In this case, the area is 49d + 91, and the length is a known number, so we know the value of L.
Then we can write:
A = L*W = 49d + 91
To get the value of W, we need to isolate it on one side of the equation.
We can do that by dividing both sides by L.
[tex]W = \frac{49d + 91}{L}[/tex]
We assume that d and L are known, so with the above rational expression, we have W totally determined.
