A submarine left Diego Garcia traveling east 5 hours before an aircraft carrier. The aircraft carrier traveled in the opposite direction going 10 km/h faster than the submarine for 2 hours after which time the ships were 110 km apart. Find the submarine's speed
Answer:
40km/hStep-by-step explanation:
Let the submarine's speed be x km/h
the time taken by the submarine is given as 5 hours
the aircraft travels 10km/h faster than the submarine= 15km/h
time taken by the aircraft is 2hours
therefore the distance covered by both vehicles can be described using the expression below
we know that distance=velocity*time, so equating the two vehicles distance to 110km we have
5*x+15*2=110
5x+30=110
solving for x we have
5x=110-30
5x=80
divide both sides by 5 we have
x=80/5
x=40km/h
The submarine's speed is 40km/h

Jill says that 23/1000 can be written as 0.23. Which explains whether or not Jill is correct? A. Yes, Jill is correct. The fraction 23/1,000 is equivalent to 0.23. B. No, Jill is not correct. The fraction is equivalent to 0.023. The decimal 0.23 is equivalent to. C. No. Jill is not correct. The fraction is equivalent to 0.0023. The decimal is 0.23 is equivalent to 23/100. D. No, Jill is not correct. The fraction 23/1,000 is equivalent to 2.3. The decimal 0.23 is equivalent to 23/100. D. No, Jill is not correct. The fraction 23/1,000 is equivalent to 2.3. The decimal 0.23 is equivalent to 23/100.
Answer:
B. No, Jill is not correct, the fraction is equivalent to 0.023.
Step-by-step explanation:
The given fraction is [tex]\frac{23}{1000}[/tex]
Observe that in the denominator there is 1000, which has three zeros after 1.
In changing the given fraction to decimal, there must be 3 significant digits after the decimal.
According to this option (b) is correct.
Moreover, when 23 is divided by 1000, we have
[tex]\frac{23}{1000}=0.023[/tex]
But Jill says that 23/1000 can be written as 0.23, so, Jill is not correct.
Hence option (b) is correct,
Solve for the value of m
Answer:
m = 7
Step-by-step explanation:
The 3 given angles lie on a straight line, thus sum to 180° , then
8m - 4 + 90 + 5m + 3 = 180, that is
13m + 89 = 180 ( subtract 89 from both sides )
13m = 91 ( divide both sides by 13 )
m = 7

Find the length of the rectangle if x= 10.
And find the perimeter if x=10
PLEASE HELP .
Answer:
34
Step-by-step explanation:
10+2=12
12 on both sides=24
5 on both sides=10
10+24=34
The perimeter of the rectangle is 34 for the given sides.
What is the perimeter of the rectangle?The rectangle is defined as a quadrilateral having four sides and the angle suspended by all the sides is equal to 360 degrees. The perimeter is the sum of all the sides of the rectangle.
Given that the two sides of the rectangle are 5 and x + 2. The value of x is 10.
The perimeter of the rectangle will be calculated as:-
L = 10+2=12
12 on both sides=24
5 on both sides=10
Perimeter = 10+24=34
Therefore, the perimeter of the rectangle is 34 for the given sides.

Each day for two workweeks (10 days total), George weighs 4 bags from that day’s production. If the average of the means is 14 oz. and the average range is 0.4 oz., what is the lower control limit for an x-bar chart for this process?
a. 13.7084 oz.
b. 13.8768 oz.
c. 14.2916 oz.
d. 12.8000 oz.
e. 13.5908 oz.
Answer:
a. 13.7084 oz.
Step-by-step explanation:
Formula for Lower Control Limit =
(LCL = x-bar - A²R-bar)
x - bar = 14 oz
A2 = 0.729
R - bar = 0.4 oz
= 14 - 0.729 × 0.4
= 14 - 0.2916
= 13.7084oz

A cylinder has a base diameter of 4 centimeters and a height of 4 centimeters. What is its volume in cubic centimeters, to the nearest tenths place
Answer:
50.3 cm³
Step-by-step explanation:
Use the cylinder volume formula:
V = [tex]\pi[/tex]r²h, where r is the radius and h is the height.
Since the radius is half of the diameter, and the cylinder has a diameter of 4 cm, this means the radius is 2 cm.
Plug in the radius and height into the equation:
V = [tex]\pi[/tex]r²h
V = [tex]\pi[/tex](2²)(4)
V = 16[tex]\pi[/tex]
V = 50.3 cm³
Answer:
50.3 cm³
Step-by-step explanation:
Use the cylinder volume formula:
V = r²h, where r is the radius and h is the height.
Since the radius is half of the diameter, and the cylinder has a diameter of 4 cm, this means the radius is 2 cm.
Plug in the radius and height into the equation:
V = r²h
V = (2²)(4)
V = 16
V = 50.3 cm³

Chris wants to order DVDS over the internet. Each DVD costs $ 15.99 and shipping for the entire order is $ 9.99. How much will Chris spend (s) if he buys x DVDS?
Answer:
There are 3 DVD s that can be bought with under $100.
Step-by-step explanation:
Since we have given that
Cost of DVD = $15.99
Cost of Shipping = $ 9.99
Total cost per DVD would be
$15.99 + $9.99 = $ 25.98
Amount he has to spend no more than $ 100.
So, number of DVDs would be
100 ÷ 25.98 = 3.84
Hence, there are 3 DVD s that can be bought with under $100.
Dan had $10. He bought x pencils, each costing y cents .How much money did Dan have left?
Answer: Unknown...Well, just simplify.
Step-by-step explanation:
Since it says x and y, that is NOT a number. So the real question is, how can we solve the problem without numbers? Well that's pretty simple and easy. Since we don't know the number, we will just have to simplify. With no actual number, simplifying is basically the answer. Unless, you can find out the answer.
Dan has the amount of money left would be 10 - xy which is the form of an expression.
What is the algebraic expression?Algebraic expressions are mathematical statements with a minimum of two terms containing variables or numbers.
We have to determine the amount of money Dan has left.
We must only generalize since we don't know the exact quantity. Having no method of solving,
Dan had $10. He bought x pencils, each costing y cents which are given in the question.
quantity of pencils = x and cost of pencil = y
As per the given condition, the required solution would be:
⇒ remaining amount = 10 - quantity of pencils × cost of pencil
⇒ remaining amount = 10 - (x) × (y)
⇒ remaining amount = 10 - xy
Therefore, Dan has the amount of money left would be 10 - xy which is the form of an expression.

Find the equation of the line that has a slope of -½ and passes through the point (-6,9)
Answer:
y = -1/2x +6
Step-by-step explanation:
We can use the slope intercept form of a line
y = mx+b where m is the slope and b is the y intercept
y = -1/2x +b
Substitute the point into the equation
9 = -1/2 (-6) +b
9 = 3+b
9-3 =b
6 =b
y = -1/2x +6

THANK YOU!!!
==========================================
Work Shown:
The given angles are a linear pair, so they are supplementary.
(1+5x)+(3+3x) = 180
1+5x+3+3x = 180
(5x+3x)+(1+3) = 180
8x+4 = 180
8x+4-4 = 180-4 .... subtract 4 from both sides
8x = 176
8x/8 = 176/8 ..... divide both sides by 8
x = 22
------------
Extra info:
1+5x = 1+5*22 = 1+110 = 111
3+3x = 3+3*22 = 3+66 = 69
111+69 = 180, which helps confirm the answer.
