Joey is trying to prove that CATS is an isosceles trapezoid. He starts by providing that line segment AT is parallel to line segment CS and that line segment AS is about the same as line segment CT. Based on that information, is this enough to prove that CATS is an isosceles trapezoid
Answer:
Yes the information i.e. AT ║ CS and diagonals AS = CT are sufficient to prove that CATS is an isosceles trapezoid.
CATS is an isosceles trapezoid. (Proved)
Step-by-step explanation:
Yes the information i.e. AT ║ CS and diagonals AS = CT are sufficient to prove that CATS is an isosceles trapezoid.
Proof :
Taking Δ CAT and Δ STA,
(i) CT = AS (Given)
(ii) AT is the common side and
(iii) ∠ ACT = ∠ TSA
{Since AT ║ CS and the angles are obtained from the same base AT}
Therefore, by the criteria Side-Side-Angle i.e. SSA, we can say Δ CAT ≅ Δ STA.
Hence, AC = ST {Corresponding sides}
Therefore, CATS is an isosceles trapezoid. (Proved)

A container has peppermint gum and spearmint gum. There are 24 pieces of peppermint gum in the container and the ratio of peppermint gum to spearmint gum is 8 to 5. Find the number of pieces of spearmint gum in the container.
Answer:
15
Step-by-step explanation:
The Number of Spearmint gum are 27 pieces
What is the ratio?It is described as the comparison of two quantities to determine how many times one obtains the other. The proportion can be expressed as a fraction or as a sign: between two integers.
Let the total number of peppermint gum and spearmint gum in the container is X
Ratio of peppermint gum to spearmint gum= 2 : 3.
Total ratio = 2+ 3=5
we are given that peppermint gum are 18 pieces , so total number of gums will be calculated as;
Ratio of peppermint/ Total ratio x Total number of gums = Number of peppermint;
2/5 x X= 18
X=(18X 5) / 2 = 45
X= Total number of gums = 45
Ratio of spearmint/ Total ratio x Total number of gums = Number of spearmint;
3/5 x 45= 27
Therefore Number of Spearmint gum are 27 pieces

Vera is an ecologist who studies the change in the bear population of Siberia over time. The relationship between the elapsed time, t, in years, since Vera began studying the population, and the total number of bears, N(t), is modeled by the function:
Answer:
Every year, the bear population shrinks by a factor of 2/3 .Explanation:
The concrete question and the function or data were omitted.
I found the complete question on the internet. Please, find attached the picture with the complete question
You must complete the sentence about the yearly rate of change of the bear population, telling whether it grows or shrinks and by what factor.
Thus, the goal is to interpret the rate of change in an exponential model.
The exponential model is:
[tex]N(t)=2187\cdot \bigg(\dfrac{2}{3}\bigg)^t[/tex]
Let's analyze that function.
When t = 0, (2/3)⁰ = 1 and N(0) = 2,187 × 1 = 2,187
Thus, the population of bears starts with 2,187 individuals.
For t = 1, the population will be N(1) = 2,187 × (2/3).
For t = 2, the population will be N(2) = 2,187 × (2/3)²
And so on, every year the population of bears is multiplied by a factor of 2/3.
Since, 2/3 is less than 1, every year the population will be decreasing (decaying), by a factor of 2/3.
Thus, the answer, i.e. the complete sentence, is:
Every year, the bear population shrinks by a factor of 2/3 .
Answer:
shrinks/ 2/3

The area of the shaded circle below is 78.5 square inches. The area of the large circle is 314 square inches.A shaded circle is inside of a larger unshaded circle.What is the probability that a point chosen at random will be in the shaded region
Answer:
The probability that a point chosen at random will be in the shaded region is 0.25
Step-by-step explanation:
We have been given a small shaded circle inside a larger un-shaded circle. This is shown in the image attached below.
The area of smaller circle is 78.5 squares inches and the area of larger circle is 314 square inches. We have to find the probability that a point chosen at random will be in the shaded region.
Probability is defined as the ratio of Favorable outcome to the Total outcomes. In this case the favorable outcome is that the point should be inside the shaded region i.e. in an Area of 78.5 square inches. And the total outcome is that the point can be anywhere inside the larger circle i.e. within an Area of 314 square inches. Thus the probability that a point chosen at random will be inside the shaded region will be:
[tex]Probability = \frac{\text{Favorable Outcome}}{\text{Total Outcome}} \\\\ = \frac{78.5}{314}\\\\=0.25[/tex]
Thus, the the probability that a point chosen at random will be in the shaded region is 0.25. This means there is a 25% chance that a randomly chosen point will be inside the shaded region.

if the diameter of a nickel is 0.835 in and the width of each nickel is 0.077 in what is the approximate surface area of the 2$ roll of nickels round your answer to the nearest hundredth
Answer:
Step-by-step explanation:
The roll of nickels forms a cylinder
cylinder area includes the sides and the round areas
round areas = pi r^2 there is two so 2 pi r^2
= 2 pi (.835/2)^2
and the side area pi x d x h
pi x .835 ( .077 x 40) (there are 40 nickels in $ 2
Add the areas to get the total ......
To find the total surface area of a $2 roll of nickels, we calculate the surface area of one nickel and then multiply by 40 (the number of nickels in a $2 roll), resulting in an approximate surface area of 47.84 in² when rounded to the nearest hundredth.
To calculate the approximate surface area of a $2 roll of nickels, we must first determine how many nickels are in a $2 roll. Knowing that each nickel is worth 5 cents, a $2 roll would contain 40 nickels ($2.00 / $0.05 = 40). The surface area of a nickel includes the area of the circles on both sides and the area of the edge. The formula for the area of a circle is πr² (where r is the radius) and the formula for the area of the side (cylinder height) is 2πrh (where h is the width).
The diameter of a nickel is 0.835 inches, so the radius is half of that or 0.4175 inches. Using these measurements:
Area of one side = π(0.4175²) = 0.5477 in² (approx).Area of both sides = 2 * 0.5477 in² = 1.0954 in².Surface area of the edge = 2π(0.4175)(0.077) = 0.1006 in² (approx).Total surface area of one nickel = 1.0954 in² + 0.1006 in² = 1.196 in².Therefore, the total approximate surface area for a $2 roll of 40 nickels = 40 * 1.196 in² = 47.84 in².
Rounded to the nearest hundredth, the surface area is 47.84 in².

The lengths of a certain species of beetles are normally distributed with a mean of 1.9 centimeters and a standard deviation of 0.2 centimeters.
What is the z-score of a beetle of this species with a length of 2.38 centimeters?
Answer: the z score is 2.4
Step-by-step explanation:
Since the lengths of the certain species of beetles are normally distributed, we would apply the formula for normal distribution which is expressed as
z = (x - µ)/σ
Where
x = length of the beetle species.
µ = mean length
σ = standard deviation
From the information given,
µ = 1.9 centimeters
σ = 0.2 centimeters
For a species with a length of 2.38 centimeters, the z score is
z = (2.38 - 1.9)/0.2
z = 0.48/0.2
z = 2.4
When Sanchez left his house this morning, his cell phone was 30% charged and it then started to lose 3% charge for each hour thereafter. Write an equation for the function B(t), representing the charge remaining in Sanchez's battery, as a percentage, t hours after he left his house.
Answer:
The equation that represents the battery charge in Sanchez's phone as a percentage t hours after he left his house is B(t) = 30 - 3*t.
Step-by-step explanation:
The initial state of the battery on Sanchez's phone is 30% so in time t equals zero the battery should be at that value and as time progresses the battery should lose battery charge at a rate of 3% for each hour. We can write this in an equation form by taking the initial state and subtract it by the rate multiplied by the value of time. We have:
B(t) = 30 - 3*t
The equation that represents the battery charge in Sanchez's phone as a percentage t hours after he left his house is B(t) = 30 - 3*t.

A farmer has determined that a crop of strwberries yields a yearly profit of $1.50 per square yard. If strawberries are planted on a triangul;ar piece of land whose sides are 50 yards, 75 yards, and 100 yards, how much profit to the nearest hundred dollars, would the farmer expect to make from this piece of land during the next harvest.
Answer:
$2700
Step-by-step explanation:
Using Heron's formula, we can find the area of the triangle to be ...
A = √(s(s -a)(s -b)(s -c)) . . . . where s=(a+b+c)/2 and a, b, c are the sides
Here, we have ...
s = (50 +75 +100)/2 = 225/2 = 112.5
A = √(112.5 · 62.5 · 37.5 · 12.5) ≈ 1815.461 . . . square yards
Then the profit is expected to be ...
(1815.451 yd²)($1.50/yd²) = $2723.19 ≈ $2700
The farmer expects a profit of about $2700 from that crop.
