The error that Angelica made is an error substituting the values into the Pythagorean theorem. The equation should be c² + 6² = 10²
How to use Pythagoras Theorem?
From the brainly link attached below, we can see the steps Angelica used in calculating the distance between the two points shown on the graph below.
The steps she took are;
Step 1: Use the point C(–4, –5) to make a right triangle with the 90 degree vertex at C.
Step 2: Determine the lengths of the legs: AC = 6 and BC = 10.
Step 3: Substitute the values into the Pythagorean theorem: 10² = 6² + c²
Step 4: Evaluate
From the graph and looking at the steps she took, we can say that the error that Angelica made is an error substituting the values into the Pythagorean theorem. The equation should be c² + 6² = 10²

Another order calls for 26 widgets. The widgets comes in boxes of 5. How many full boxes of 5 do you pull? How many single items do you still need?
divide 26 by 5
26 /5 = 5.2
so 5 full boxes
5*5 = 25
26-25 = 1
so 5 full boxes and 1 single widget
For an order of 26 widgets with each box containing 5 widgets, you would pull 5 full boxes and still need 1 more single widget.
Explanation:To solve this problem, we need to find out how many full boxes of 5 widgets we can make from 26 widgets and how many single widgets we will have left. Whole number quantities, such as the number of widgets and boxes, are important here. First, we divide 26 by 5 to find out the number of full boxes. This gives us 5 full boxes with a remainder of 1, which means we have one widget left. So, we pull 5 full boxes and still need 1 more single widget.

Matty jogs 9 km/hr. Identify the correct conversion factor setup required to compute Matty's speed in m/s.
Answer:
2.5 m/s
Step-by-step explanation:
we have given that Matty jogs 9 km/hr
we have to convert 9 km/hr to m/s
we know, 1 km= 1000 m
and 1 hr= 60 minutes and 1 minute= 60 seconds
which implies that 1 hr=60 x 60 = 3600 seconds
now, to convert km/hr into minute/second we have to multiply it by 1000/3600 or 5/18
i.e. 9×1000/3600= 5/2=2.5 m/s
A deep-sea diver is in search of coral reefs. He finds a beautiful one at an elevation of -120 4/7 feet. While taking pictures of the reef, he catches sight of a manta ray. He swims up 25 3/7 feet to check it out. What is the diver's new elevation?
The position of the diver's new elevation will be negative 666 / 7.

The acronym PEMDAS stands for Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This approach is used to answer the problem correctly and completely.
A remote ocean jumper is looking for coral reefs. He tracks down a wonderful one at a rise of - 120 ⁴/₇ feet. While taking photos of the reef, he sees a manta beam. He swims up 25 ³/₇ feet to look at it.
Convert the mixed fraction number into a fraction number. Then we have
- 120 ⁴/₇ = - 844 / 7
25 ³/₇ = 178 / 7
The position of the diver's new elevation will be given as,
⇒ - 844 / 7 + 178 / 7
⇒ (- 844 + 178) / 7
⇒ - 666/7
The position of the diver's new elevation will be negative 666 / 7.

A single microvillus is a rod-like structure that is 1.0 μm in height. it has a hemispherical top approximately 0.1 μm in diameter. calculate the surface area of the cylinder that forms the "sides" of the microvillus rod. use 3.14 for π.
Final answer:
The surface area of the cylinder forming the sides of a microvillus rod with a diameter of 0.1 µm and a height of 1.0 µm is 0.314 µm².
Explanation:
To calculate the surface area of the cylinder that forms the "sides" of the microvillus rod, we will use the formula for the surface area of a cylinder without the top or bottom, which is circumference multiplied by height
(A = 2πrh).
Since the diameter (d) of the microvillus is given as 0.1 µm, we first find the radius (r) by dividing the diameter by 2.
Therefore, r = 0.1 µm / 2 = 0.05 µm.
The height (h) is given as 1.0 µm.
Inserting these values into our formula, we get:
A = 2 × 3.14 × 0.05 µm × 1.0 µm = 0.314 µm².
Hence, the surface area of the sides of the microvillus rod is 0.314 µm².

During a certain week, a post office sold Rs.280 worth of 14-paisas stamps. How many of these stamps did they sell?
The post office sold 2000.
To find out how many 14-paisa stamps the post office sold to make Rs.280, we need to follow a step-by-step solution.
Convert the total amount from rupees to paisas:Since the stamp's value is given in paisas.There are 100 paisas in 1 rupee.Rs.280 = 280 x 100 = 28000 paisas.The value of one stamp is 14 paisas.To find the number of stamps sold, we divide the total amount in paisas by the value of one stamp:28000 paisas ÷ 14 paisas per stamp = 2000 stamps.

A really bad carton of 18 eggs contains 9 spoiled eggs. an unsuspecting chef picks 6 eggs at random for his "mega-omelet surprise." find the probability that the number of unspoiled eggs among the 6 selected is
Final answer:
To find the probability that the number of unspoiled eggs among the 6 selected is X, we can use the hypergeometric probability formula. This formula is used when the sample drawn is without replacement from a finite population.
Explanation:
To find the probability that the number of unspoiled eggs among the 6 selected is X, we can use the hypergeometric probability formula. This formula is used when the sample drawn is without replacement from a finite population. In this case, we have 18 total eggs in the carton, with 9 spoiled eggs. So the probability that X unspoiled eggs are selected out of the 6 can be calculated as:
P(X) = (C(X,6) * C(9,6)) / C(18,6)
Where C(n,r) represents the combination of n things taken r at a time.

From 1980 to 1990, Lior’s weight increased by 25%. If his weight was k kilograms in 1990, what was it in 1980?
Ththe weight of Lior in 1990 in terms of k is [tex]\frac{4}{5} k[/tex]
Let the weight of Lior in 1980 be "w"
If Lior's weight increased by 25%, his new weight was "k". This can be expressed as:
w + (25% of w) = k
w + (0.255w) = k
w + 0.15w = k
1.25w = k
Divide both sides by 1.25
[tex]\frac{1.25w}{1.25} =\frac{k}{1.25} \\w=\frac{k}{1.25} \\w=\frac{100k}{125} \\w=\frac{4}{5}k[/tex]
This shows that the weight of Lior in 1990 in terms of k is [tex]\frac{4}{5} k[/tex]

Is this a direct variation? 4y=x
The equation 4y = x represents a direct variation. This type of relationship between variables implies that the ratio between x and y is constant. In this specific example, the constant of variation is 0.25.
Explanation:Yes, the given equation 4y = x is a representation of direct variation. Direct variation in mathematics refers to a situation where the ratio of two variables is constant. In a direct variation equation the form is y = kx, where k is the constant of variation. Here, you can rewrite 4y = x as y = x/4 or y = 0.25x, so the constant of variation is 0.25. It's important to note that a direct variation has no y-intercept, it always passes through the origin (0,0) which is the case in this equation.
