P= 3in
a) find the length of each side of the square
b) find the area of the square
Step-by-step explanation:
what does P mean ?
I assume it is perimeter ?
what is the perimeter of a square ?
come on, there is practically nothing in math that is easier to solve.
a square has 4 equal sides.
so, to go one time around the whole square, we have to go along every one of its 4 sides (which are all of equal length).
so, when I get the perimeter number, I know this is the result of all 4 sides added together.
and how can we express having 4 times the same number ? exactly how we say it in English : 4 times the number.
therefore
P = 4 × side length
and from there we can immediately deduct
side length = P / 4 = 3/4 in
now we know how long the sides of the square are.
what is the area of the square ?
like for any rectangle the area is length×width. just that length=width, so that we end up with length×length = length².
therefore, the area is
3/4 × 3/4 = (3/4)² = 9/16 in²
this is important : a length is measured e.g. in inches (in). an area is then measured in square-inches = in²
if (p+2q)/p = 7/5 , find the value of q/p , where p ≠ 0
Work Shown:
(p+2q)/p = 7/5
(p/p)+(2q/p) = 7/5
1 + 2(q/p) = 7/5
2(q/p) = 7/5 - 1
2(q/p) = 7/5 - 5/5
2(q/p) = (7-5)/5
2(q/p) = 2/5
q/p = (2/5)*(1/2)
q/p = (2*1)/(5*2)
q/p = 1/5
Answer:
q/p = 1/5
Step-by-step explanation:
(p+2q)/p = 7/5
Multiply each side by p
(p+2q)/p *p = 7/5*p
(p+2q) = 7p/5
Multiply each side by 5
(p+2q)*5 = 7p/5 *5
5p + 10q = 7p
Subtract 5p from each side
5p + 10q -5p = 7p -5p
10 q = 2p
divide each side by p
10q/p = 2p/p
10 q/p = 2
Divide each side by 10
q/p = 2/10
q/p = 1/5

Answer:
105
Step-by-step explanation:
Because the lines are parallel, we know that those angles have to add up to 180. so we just do
x+75=180
or 180-75=105
x+75°=180°
x=180°-75°
x=105°
or
180°-75° = 105°

Sue has 3 cats. Each cat eats 1 4 of a tin of cat food each day. Sue buys 4 tins of cat food. Has Sue bought enough cat food to feed her cats for 5 days? You must show how you get your answer
Answer:
3 3/4 tins of food
Step-by-step explanation:
Number of cats = 3
Quantity of food for each cat per day = 1/4 of a tin
Total tins of cat food sue bought = 4 tins
Has Sue bought enough cat food to feed her cats for 5 days?
Quantity of food 3 cats eat per day = Quantity of food for each cat per day × Number of cats
= 1/4 × 3
= 3/4 of a tin
Total Quantity of food 3 cats eat for 5 days = Quantity of food 3 cats eat per day × 5 days
= 3/4 × 5
= (3 * 5) / 4
= 15/4
= 3 3/4 tins of food
Total Quantity of food 3 cats eat for 5 days = 3 3/4 tins of food
Recall,
Total tins of cat food sue bought = 4 tins
Therefore, Sue bought enough cat food to feed her cats for 5 days

Use the vertical motion formula h = –16t2 + vt + c.
A child tosses a ball upward with a starting velocity of 10 ft/s from a height of 3 ft. Substitute the values into the vertical motion formula and let h = 0. Use the quadratic formula to solve for t. How long is the ball in the air?
A.
0.8 s
B.
0.8 s or –0.2 s
C.
0.2 s
Answer:
t = -0.22secs and 0.85secs
Step-by-step explanation:
Given the expression
h = –16t² + vt + c.
If a child tosses a ball upward with a starting velocity of 10 ft/s from a height of 3 ft, then;
v = 10, c = 3
Since we are to let h = 0, then the equation becomes:
0 = –16t² + 10t + 3
Multiply through by a minus sign
16t² - 10t - 3 = 0
Factorize the reulting expression:
t = -(-10)±√(-10)²-4(16)(-3)/2(16)
t = 10±√100+192/32
t = 10±√292/32
t = 10±17.09/32
t = 10-17.09/32 and 10+17.09/32
t = -7.09/32 and 27.09/32
t = -0.22secs and 0.85secs

The length of a rectangular playing field is 5m longer than its width. If the perimeter of the field is 150m,find it's width
Answer:
35
Step-by-step explanation:
Make equations, l = w+5 and 2l + 2w = 150
Substitute w+5 into 2l + 2w = 150
Simplify to get 4w + 10 = 150
Subtract 10 from both sides to get 4w = 140
Divide both sides by 4 and you get 35 as width
Answer:
The width of the field is 35 meters.
Step-by-step explanation:
Recall that the perimeter of a rectangle is given by:
[tex]\displaystyle P = 2(w+\ell)[/tex]
Where w is the width and l is the length of the rectangle.
We know that the perimeter is 150 meters. Thus:
[tex]150=2(w+\ell)[/tex]
Divide both sides by two:
[tex]75=w+\ell[/tex]
We are given that the length is five meters longer than the width. So:
[tex]\ell = w+5[/tex]
Substitute:
[tex]75=w+(w+5)[/tex]
Combine like terms:
[tex]75=2w+5[/tex]
Subtract five from both sides:
[tex]70=2w[/tex]
And divide both sides by two. Hence:
[tex]w=35[/tex]
Thus, the width of the rectangular field is 35 meters.

Answer:
In addition, from the response shown, using a graphical calculator brings the following benefits:
1) You can write the system of linear equations as big as you want. This is: systems 3 * 3, 4 * 4, 5 * 5.
2) The response to systems of equations greater than 2 * 2 can be complicated when you graph the solution, therefore, the graphing calculator can be much more efficient in these cases.
3) You can write the linear equations in any way. Resolving by hand you should probably rewrite the system of equations to find the solution.

Step-by-step explanation:
The probability of any given outcome is the ratio of the number of ways that outcome can happen to the total number of outcomes.
P(4) = 1/6 . . . . . roll = 4 is one of 6 possible outcomes
P(odd) = 3/6 = 1/2 . . . . . of the 6 possible outcomes, 3 are odd
__
The two rolls of the die are presumed to be independent, so the probability of the two outcomes is the product of their individual probabilities.
P(4 & odd) = (1/6)(1/2) = 1/12

The median will be located in the (n + 1)/2 th data point
Therefore the median is the (31 + 1)/2 = 16th data point
The sum of the first three bars on the histogram = 11
The sum of the first four bars on the histogram = 18
Therefore, the 16th data point is located in the fourth bar which has x value of 5
The median is therefore, C. 5
