Answer:
3.5 meters
Step-by-step explanation:
Equation: p = 0.8L
Given: p = 2.80
To find the length of a piece of nylon rope that costs $2.80, input the given value of p(2.80) into the equation and solve for L:
p = 0.8L
2.8 = 0.8L
Divide both sides by .8 to isolate L:
[tex]\frac{2.8}{0.8} =\frac{0.8L}{0.8}[/tex]
3.5 = L
The length of a piece of nylon rope that costs $2.80 is 3.5 meters long.

A bag of candy contained the flavors strawberry, orange, cherry, and lemon. Zelda drew each
piece of candy out of the bag and recorded the frequency of each.
Which candy's experimental probability is closest to its theoretical probability?
Answer: Strawberry
Step-by-step explanation: Strawberry has the highest candies so it has the highest chance of being pulled out.
A local zoo has two large snakes. The anaconda is currently 5.23 meters long and grows 1.27 meters every month. The python is 4.76 meters long and grows 2.04 meters per month. How many months (m) does the zookeeper need to wait for the two snakes to be the same length?
Answer:
1 months
Step-by-step explanation:
Given
Anaconda
[tex]Length = 5.23m[/tex]
[tex]Growth = 1.27m[/tex] monthly
Python:
[tex]Length = 4.76m[/tex]
[tex]Growth = 2.04m[/tex] monthly
Required
Determine when their length will be equal
First, we need to write equations that determines the growth of each snake in m months.
For both snakes;
[tex]Expression = Length + Growth * m[/tex]
For the Anaconda, the expression is:
[tex]5.23 + 1.27 * m[/tex]
[tex]5.23 + 1.27 m[/tex] --- (1)
For the Python, the expression is
[tex]4.76 + 2.04 * m[/tex]
[tex]4.76 + 2.04m[/tex] ---- (2)
Both snakes will have equal length when both expressions (1 & 2) are equal
[tex]4.76 + 2.04m = 5.23 + 1.27 m[/tex]
Collect Like Terms
[tex]2.04m - 1.27 m= 5.23 - 4.76[/tex]
[tex]0.77 m= 0.47[/tex]
Solve for m
[tex]m = \frac{0.47}{0.77}[/tex]
[tex]m = 0.61[/tex]
[tex]m = 1[/tex] --- Approximated
Hence, the zookeeper will wait for 1 month

Will ran the diagonal distance across a square field measuring 40 yards on each side. James ran the diagonal distance across a rectangular field with a length of 25 yards and a width of 35 yards. Who ran a longer distance, and how much longer did he run?
Answer: The distance across a rectangular field is longer distance.
So, Perimeter of rectangle would be 120 yards.

Shoppers at a grand opening for a sporting goods store receive a gift bag when they make a purchase. How often will a bag contain both a T-shirt and socks? Items in the Gift Bag T-shirt Every 4th bag Socks Every 3rd bag
Answer:
Every 12th bag
Step-by-step explanation:
Given that:
Gift bag contains :
T - shirt = every 4th bag
Socks = Every 3rd bag
To obtain how often gift bag contains both T-shirt and socks , obtain the Lowest common multiple of 4 and 3
Multiples of :
4 : 4, 8, 12, 16, 20, 24,....
3 : 3, 6, 9, 12, 15, 18, 21, 24,....
Hence, the lowest common multiple of both 4 and 3 is 12.
The bag will contain both T-shirt and socks after every 12th bag
Find the slope of the line between the points (-2, 7) and (10, 3)
Answer:
m = -1/3
Step-by-step explanation:
What expression gives the distance between the points (4,6) and (7,-3)?
Answer:
[tex]\sqrt{(-3^2-6)+(7^2-4^2)}[/tex]
Step-by-step explanation:
Use the form: [tex]\sqrt{(x^2-x^1)+(y2-y1)^2[/tex]
so: [tex]\sqrt{(-3^2-6)+(7^2-4^2)}[/tex]
By the distance formula,
[tex]d = \sqrt{( x_2 - x_1) {}^{2} + (y_2 - y_1 {)}^{2} }[/tex]
Here,
[tex]x_1 = 4[/tex]
[tex]y_1 = 6[/tex]
[tex]x_2 = 7[/tex]
[tex]y_2 = - 3[/tex]
Hence,
[tex]d = \sqrt{( {7 - 4)}^{2} + {( - 3 - 6)}^{2} } [/tex]
[tex]d = \sqrt{ {3}^{2} + ( - {9)}^{2} } [/tex]
[tex]d = \sqrt{9 + 81} [/tex]
[tex]d = \sqrt{90} [/tex]

The ratios 250 miles in 4 hours and 500 miles in 8 hours are equivalent.
Answer:
Yes, they are equivalent
Step-by-step explanation:
Case 1,
Distance = 250 miles
Time = 4 hours
Ratio = speed = distance/time
= 250 miles/4 hour
= 62.5 mph
Case 2,
Distance = 500 miles
Time = 8 hours
Ratio = speed = distance/time
= 500 miles/8 hour
= 62.5 mph
In both cases, the ratios 250 miles in 4 hours and 500 miles in 8 hours are equivalent.

Find the measures of ∠B and ∠C given that m∠B=(2.5x+6)∘ and m∠C=(7x−12)∘.
The figure shows triangle A B C. Side A B is congruent to side A C.
answers are one of the following
∠B = 4° and ∠C = 4°
∠B = 16° and ∠C = 16°
∠B = 20° and ∠C = 20°
Answer:
since AB=AC it is an isosceles triangle so ...
Step-by-step explanation:
angle B = angle C
2.5x + 6 = 7x - 12
4.5x = 18
therefore x = 4
substituting the value of x we get answer
angle B = 16
angle C = 16

tytrugivffhet GG hfjeyrebrwryehyeujxhfrA nutrition label on a can of tuna fish states that every 1/4 cup of tuna has 1/2 gram of fat. How many cups of tuna are there for every gram of fat?
Answer: 1/2 cups
Step-by-step explanation:
Given that:
Every 1/4 cup of tuna has 1/2 gram of fat
How many cups of tuna are there for every gram of fat:
Let cup of tuna for 1 gram of fat = t
Hence, If
1/4 cup of tuna = 1/2 cup of fat
t tuna = 1 cup of fat
Cross multiply :
1/2 t = (1/4 * 1)
1/2 t = 1/4
t = 1/4 ÷ 1/2
t = 1/4 * 2/1
t = 2/4
t = 1/2
Hence, 1/2 cups of tuna for every gram of fat
