For the first one its a slope of -2/3
The second one is 4/5
and the third one is -1/7
question is below
Answer:
45=9⋅5 , so 2√45 is the same as 2⋅√9⋅5 . The √9=3 , so a 3 can be removed. leaving 2⋅3√5 , or 6√5
mary works for a commission of 12% on all goods she sell for the month if her basic salary is 3000 per month and she sells $2500 worth of goods for a certain month calculate mary's gross salary for that particular month
Answer:
3300
Step-by-step explanation:
Formula
Gross Salary = Basic + Commission
Givens
Basic = 3000
% = 12%
Solution
Gross = 3000 + 12/100 * 2500
Gross = 3000 + 30000/100
Gross = 3000 + 300
Gross = 3300

Explain how to solve the equation
b-7=12
Answer:
[tex]b = 19[/tex]
Step-by-step explanation:
1) Add 7 to both sides.
[tex]b = 12 + 7[/tex]
2) Simplify 12 + 7 to 19.
[tex]b = 19[/tex]
Therefor the answer is, b = 19.
Answer:
Sample Response
Step-by-step explanation:
Use the inverse operation to isolate the variable. Undo the subtraction of 7 by adding 7 to each side of the equation. – 7 + 7 = 0, and 12 + 7 is 19. The solution is b = 19. Check the solution by substituting 19 for b in the original equation, and then simplify. 19 – 7 is 12 and 12 = 12 is a true statement, so 19 is the solution.

Hey there!
The answer is 6:54
The time on the clock shows 6:20, because the hour hand is after the 6, and the minute hand is on the 4 (which we multiply by 5 to get the minutes).
If it takes her 8 minutes to walk to the bus, 10 to pack lunch, and 16 to get dressed, that's a total of 8 + 10 + 16 minutes, or 34 minutes.
So, we add that to the minutes, so 20 + 34 = 54, therefore the time is 6:54 when she arrives.

A bird can lay either white or brown eggs. Three white eggs
and
two brown eggs have a mass of 13 grams, while five white eggs
and four brown eggs have a mass of 24 grams. Find the mass
of a brown egg and of a white egg.
Answer:
Mass of brown egg = 3.5 grams
Mass of white egg = 2 grams
Step-by-step explanation:
Let
Mass of brown eggs = x
Mass of white eggs = y
3y + 2x = 13 (1)
5y + 4x = 24 (2)
Multiply (1) by 5 and (2) by 3 to eliminate y
15y + 10x = 65 (3)
15y + 12x = 72 (4)
Subtract (3) from (4)
12x - 10x = 72 - 65
2x = 7
x = 7/2
x = 3.5
Substitute x = 3.5 into (1)
3y + 2x = 13 (1)
3y + 2(3.5) = 13
3y + 7 = 13
3y = 13 - 7
3y = 6
y = 6/3
y = 2
Mass of brown egg = 3.5 grams
Mass of white egg = 2 grams
Phil is riding his bike. He rides 25 miles in 2 hours, 37.5 miles in 3 hours, and 50
miles in 4 hours. Find the constant of proportipnality and write an equation to
describe the situation. Let x represent the number of hours.
The equation that describes the relationship is y =
The constant of proportionality (known as "speed" in this case) is 12.5 miles per hour.
The equation is
d
=
12.5
×
t
Explanation:
To find the constant of proportionality, divide one value in each pair by the other. If this relationship is a true direct proportionality , when you repeat these for every pair, your will come up with the same value:
For example
25
miles
÷
2
hours
=
12.5
miles
hour
A direct proportionality will always result in an equation that resembles this:
y
=
k
x
where
y
and
x
are the related quantities and
k
is the constant of proportionality. If you draw a graph using the values you have, the graph will show a straight line the passes through the origin. The slope of this line will be the constant of proportionality. (And if the values given are real physical quantities, this constant will contain important information about the situation you are studying!)
The figure below shows an upside-down pyramid with a square base.
Which shape does the intersection of the horizontal plane with the pyramid look like?
Answer:
B
Step-by-step explanation:
A square pyramid is one with a square base. The correct option is B.
What is a square pyramid?A square pyramid is one with a square base. It is a right square pyramid with C4v symmetry if the top is perpendicular to the centre of the square. It is an equilateral square pyramid if all edge lengths are equal.
The place at which the up-side down pyramid will intersect with the plane will be a square.
Hence, the correct option is B.

Airplanes use radar (radio waves) to measure distances.
The plane is at a height of 5200 m. The airport is 10.2 km away.
How far does the plane need to travel before it lands?
a) 11.4 km
b) 10.4 km
c) 5200 km
d) 10.2 km
Answer:
10.2 km
Step-by-step explanation:
I thought we have to add 5200 m + 10,2 km, but for this result there is no an alternative. So the correct answer must be 10,2 km, if the plane is right above the airport.
