Answer:
(a) 18.5ft
(b) 388.5 ft²
Step-by-step explanation:
(a)
She has 79ft of fence = the perimeter will be 79.
Perimeter of a rectangle = 2(length) +2(width)
79 = 2(21)+2(width)
2(width) = 79 - 42
width = 37/2
width = 18.5ft
(b)
Area of a rectangle = (length)(width) = (21)(18.5) = 388.5 ft²

The denominator of a fraction is 7 more than the numerator. If 1 is added to the numerator and 6 is added to the denominator, the value of the fraction will be ½. Find the numerator and the denominator.
Answer:
Let x=numerator,
y=denominator.
y=x+7 - - - - - (i)
(x+3)/(y+3) = 2/3
(Cross multiply)
3(x+3)=2(y+3)
3x+9=2y+6
(subtract 9 from both sides)
3x+9–9=2y+6–9
3x=2y+6–9
3x=2y-3 - - - - - - - (ii)
(substitute the value of equation (i) into (ii))
3x=2(x+7)-3
3x=2x+14–3
3x=2x+11
(subtract 2x from both sides)
3x-2x=2x+11–2x
x=11.
(substitute the value of x into equation (i))
y=7+11
y=18.
so numerator =11,
numerator =11,denominator = 18.
So original fraction is 11/18.
3/11th of original fraction is
= 11/18 x 3/11
= (11x3)/(18x11)
= 3/18
=1/6.
Answer = 1/6.
Answer:
Step-by-step explanation:
let numerator be x and denominerator be y
according to the question equation is
1+x /7+x+6=1/2( do cross multiplication)
7+x+6=2(1+x)
13+x=2+2x
13-2=2x-x
11=x
numerator =x+1=11+1=12
therefore numerator is 12
for denominerator
substitute the value of x in (7+x+6)
=7+11+6

Using technology we found the equation of the line to be y=-2x + 25. Using the given equation
predict the value of a car that is 3 and a half years old.
Answer:
A car that is 3 and a half years old would cost $18,000
Step-by-step explanation:
Using the given equation, [tex]y=-2x+25[/tex], we replace 'x' with '3.5' and solve for 'y'.
[tex]y=-2(3.5)+25[/tex]
[tex]y=-7+25[/tex]
[tex]y=18[/tex]
Dollar values on the graph are expressed in thousands. Thus, we multiply 18 by 1,000 to get $18,000

Marcia is mixing lemonade. She use 3 parts water to 1 part syrup. If she has 9 parts water, how much syrup will she need to complete the mixture?
Answer:
if Marcia uses 9 parts water, that mean she will have to use 3 parts syrup
Step-by-step explanation:
this is ratios,
so to find out how many syrup she needs, you need to see how much she used water from the original recipe
so:
9 ÷ 3 = 3
so she multiplied three to get to nine, so we have to do the same to the syrup
_ ÷ 1 = 3
or:
3 × 1 = 3
so the answer is 3

Answer:
The awnswer is b c and e
Step-by-step explanation:
I submmited it and got it right hope this helps :D
The shapes which have all the properties shown are C. Rectangle and E. Square.
What are Isosceles Triangles?Isosceles triangles are defined as the triangles for which two sides or two angles are equal to each other.
Given properties are,
At least 2 sides of equal length
2 pairs of parallel sides
At least 2 right angles
Since the property includes that 2 pairs of parallel sides, it must contain 4 sides in total.
So triangle can't be a possible shape.
Parallelogram can't also be possible since there are no right angles.
Only right trapezoids are possible since the other ones will not have al least two right angles.
Rectangle and square are possible.
Hence the correct shapes are Rectangle and Square.

Challenge: Laura buys a 10 pound bag of dog food. She feeds her dogs 22 ounces of food per day. Will the bag of dog food last a whole week? Explain.
Answer:
Yes, the dog food will last a whole week
Step-by-step explanation:
1 pound=16 ounces, so
10 pounds=10*16=160 ounces.
There are 7 days in a week, so if Laura feeds her dogs 22 ounces per day, she will need 7*22=154 ounces to last a whole week.
She buys 160 ounces, which is greater than 154, so yes.
Answer:
Yes, the food will last the whole week
Step-by-step explanation:
10 pounds is 160 ounces. If you multiply 22 by 7 you'll get 154.
