Wilma can mow a lawn in 90 minutes. Vanessa can mow the same lawn in 30 minutes.
How long does it take for both Wilma and Vanessa to mow the lawn if they are
working together?

Answers

Answer 1

Answer:

If it takes Wilma 90 minutes and Vaness 30 minutes you'll need to add 90 + 3.

If add both numbers correctly the answer that you'll get will be 2 hours.

Hope this helped :)

The mall is 6 miles west of the highway. The hospital is 12 miles west of the mall. How far, and in what direction, is the hospital from the highway?

Answers

Answer: 18 miles west

Step-by-step explanation:

The mall is west of the highway.

The hospital is then west of the mall.

If the hospital is west of the mall which is already to the west of the highway, the Hospital must be west of the highway as well.

The hospital is 12 miles west of the mall which is then 6 miles west of the highway. As they are both west, it is a continuous distance and we can simply add their distances up and assume the distance is linear.

The distance between the hospital and the highway is therefore:

= 12 + 6

= 18 miles west

Enter the value for that makes the given equation true.

Answer:

  9 square units

Step-by-step explanation:

Pick's theorem is a useful relationship in circumstances like these. It tells you the area is ...

  A = i + b/2 - 1

where i is the number of interior points (8), and b is the number of points on the border (4).

The area of this figure is ...

  A = 8 + 4/2 -1 = 9

The area of the polygon is 9 square units.

_____

You can also get there by realizing the bounding rectangle is 4 units square. From that, corner triangles are cut. CW from upper left, those triangles have (base, height) dimensions of (3, 2), (1, 3), (3, 1), and (1, 2). So, the total of their areas is (1/2)(6 +3 + 3 +2) = 7 square units. The shaded area is then 16-7 = 9 square units, same as above.

How do i know this answer to this question ?? Joe has a total of 94 stamps in his stamp collection. He collected 27 in April and 34 in May. How many did he collect in June?

Answers

Answer:

Stamp collected in June = 33

Step-by-step explanation:

Total stamp = 94

Stamp collected in April = 27

Stamp collected in May = 34

Stamp collected in June = x

Total stamp = April stamp + May stamp + June stamp

94 = 27 + 34 + x

94 = 61 + x

x = 94 - 61

x = 33

Stamp collected in June = 33

Write an equation for the length (l) in terms of the width (w).

Use your understanding of simultaneous equations to determine the unknown
dimensions.

Find the area of the rectangle.

Answers

Width of rectangle = x
Length =3x+7
Perimeter of rectangle = 158cm
2(l+w)=158
2(3x+7+x)=158
2(4x+7)=158
8x+14=158
8x=158-14
x=144/8
x=18
Therefore the width of the rectangle is 18cm
Length=3x+18+7
54+7=61cm
Area=lxw

he would charge $4 for half a gallon of milk

Answer:

That it's confusing to you is understandable, these problems are confusing, They take a bunch of real world things and put it into abstract concepts. The graph of the line is just that, an idea of how math represents the cost of the milk.

Step-by-step explanation:

the graph you are given is a straight line, not all graphs are straight lines, but b/c it's a straight line we get to "categorize" it as linear.  linear graphs are nice to work with,  as compared to curvey  ones.  aka  non-linear. There are a few famous formulas that go along with linear graphs.  Remember graphs are just representations of info in a way that we can use math to understand that real thing in abstract ways.  

the problem asks what is the slope of the line.  Think of the idea of a mountain slope here,  when we look at the graph.. and move over it like we would read,  from left to right, the graph moves up hill.. or positive,  so this graph is a positive slope graph.  now we just need to figure out a way to say that with numbers.  

often times slope is represented with the variable 'm' .  why 'm' you ask?  it's just a convention, it's not important which letter you use to represent slope but by convention we use 'm'   There is a formula for slope that goes like this,

m = (y2-y1) / (x2-x1)

we can use that to find the slope of this line, but we already know it's positive just by quickly looking at the graph.

the x's and y's in the formula are the x and y points of some exact point on the graph that we can find just by looking at the graph. :)  yes we get to make our own points.  P1  and P2  ( point 1  and point 2)

somebody has already made two nice black dots, on your graph for you, let's use those two black dots, you don't have to, but those do look convenient.  :)

using those two black dots and going from left to right.. I see the 1st point as P1 = (x1,y1) =( 2,10)  and the second point as P2 = (x2,y2) = (4,20)

then plug those into the above fomula

m = (20-10) / (4-2)

m = 10 / 2

m = 5

yep,  it's positive and steep up , that the answer to (a)

for (b)

we just need the formula called the point slope

y = mx + b

since we know m

y = 5x + b

for use b = 0

so just

y = 5x

now plug in x= 1/2, for the 1/2 gallon of milk

y = 5(1/2)

y = 2/5  

that's (b)  :)
