AB = 14
DE =7
Step-by-step explanation:
Remark
AB
Opposite sides of a parallelogram are equal.
AB = CD
AB = 14
DE
According to the diagram AE = 19
AD = 26 which is the same size as BC
DE = 26 - 19 = 7
DE = 7

Answers
Answer:
-4≤y≤7Step-by-step explanation:
Given the inequality expressions
4y - 7 ≤ 3y and 3y≤5y+8
For 4y - 7 ≤ 3y
Collect like terms
4y - 3y ≤ 7
y ≤ 7
For 3y≤5y+8
Collect like terms
3y - 5y ≤ 8
-2y ≤ 8
y ≥ 8/-2
y ≥ -4
Combining both solutions
-4≤y≤7
Hence the range of values of y that satisfies both inequalities is -4≤y≤7

Answer:
1012%: 4.8 L; 32%: 3.2 LStep-by-step explanation:
For mixture problems, I like to use a single variable to represent the quantity of the greatest contributor (greatest cost or greatest concentration). Let that variable be x.
1. In this problem, the amount of the greatest contributor is already fixed, so we'll use x for the amount of walnuts. The cost of the mix is ...
0.80x + 1.25(8) = 1.00(x +8)
2 = 0.2x . . . . . . . . . . . . . . . . . subtract 0.8x+8, simplify
10 = x . . . . . . . . . divide by 0.2
10 pounds of walnuts must be used.
__
2. The amount of acid in the mix is ...
12%(8 -x) +32%(x) = 20%(8)
20%(x) = 8%(8) . . . . . . . . . . . . subtract 12%(8)
x = 8(8)/20 = 3.2 . . . . . . . . . . divide by 20%
8-x = 4.8
3.2 liters of 32% acid must be mixed with 4.8 liters of 12% acid

Comment on mixture problems
The general solution for mixture problems that have a greater contributor (G), a lesser contributor (L), and a mix value (M) is ...
g/l = (M -L)/(G -M) . . . . . . ratio of quantities of G and L
In the first problem, this becomes ...
8/l = (1.00 -.80)/(1.25 -1.00) = .2/.25 = 4/5 ⇒ l = 8(5/4) = 10
In the second problem, this becomes ...
g/l = (20-12)/(32-20) = 8/12 = 2/3 ⇒ g = (2/5)(8) = 3.2; l = (3/5)(8) = 4.8
In this case, we recognize that the ratio of 2 parts to 3 parts means that the greater contributor is 2 of 5 total parts.

(3n - 4p) centimeters. Which expression represents the perimeter, in centimeters,
of the rectangle?
Answers

|The angles in a triangle are in the ratio 1:1:4
|(a) Find the size of the largest angle?
b) what type of triangle is it?
Answers
Since the internal angle sum of a triangle is 180 degrees, and the angles are in ratio if 1:1:4, the angles with that's corresponding to the 1 will have value of 180/6=30 degrees.
The largest angle will have value 30*4=120 degrees.
This is an obtuse triangle because largest angle>90 degrees.

You have $500 in a savings account. How long will it take to double that
amount at an 8% annual interest rate?
Answers
Answer:
Step-by-step explanation:
The formula for compound annual interest is A = P(1 + r)t where
A = Accumulated or final amount (double $500 = $1000)
P = Principal or original amount ($500)
r = Rate as a decimal (0.08)
t = Time in years
1000 = 500(1 + 0.08)t
2 = 1.08t
Take the logarithm of both sides. I prefer the natural logarithm ln, but if you're more comfortable with base 10 logs they will work just as well
ln(2) = ln(1.08t)
ln(2) = t*ln(1.08)
t = ln(2)/ln(1.08)
t = 9.0065 years
Check: 500*1.089.0065 = $1000

Your class wants to raise more than $350 for the Freshman Party and you choose to sell candy and cookies to accomplish this task. You earn $6 on each basket of candy, b, and $3 on each box of cookies, c, that you sell. If the number of boxes of cookies sold is 78, at least how many baskets of candy will you need to sell to reach your goal?
Answers
Answer:
16 baskets of candy.
Step-by-step explanation:
78 boxes of cookies times $3 per box equals $234.
$350-$234=$116 left you need to make so-
each basket of candy earns $6, divide $116 by $6 to equal 56.
You will need to sell 56 baskets of candy at $6 each to reach your goal of $350 .
If r varies directly as t andr= -20 when t = 4, find r when t= -6.
Answers
Answer:
Step-by-step explanation:
t r = k/t Where k = constant of proportionality 132 = k/4 k = 4 x 132 k = 528 Formula r = 528/t Using formula r = 528/32 r = 16.5 Hope this helps :-) ...
The value of r should be considered as the 16.5 at the time when t = 4.
Calculation of the value of r:Since we know that
t r = k/t
here k = constant of proportionality
So,
132 = k/4
k = 4 x 132
k = 528
Now
r = 528/t
r = 528/32
r = 16.5
hence, The value of r should be considered as the 16.5 at the time when t = 4.
