Answer:
The student had a total of 25 questions on his test.
Step-by-step explanation:
Given that:
Number of questions answered correctly in the test = 20
Percentage scored in the test = 80%
Let,
x be the total number of questions on test.
We know that 80% of the test is 20 questions, therefore,
80% of x = 20
[tex]\frac{80}{100}x=20\\0.8x=20[/tex]
Dividing both sides by 0.8
[tex]\frac{0.8x}{0.8}=\frac{20}{0.8}\\x=25[/tex]
Hence,
The student had a total of 25 questions on his test.

Jada is buying 4 stamps that cost $0.49 each. How can rounding be used to estimate the total cost of the stamps?
Since each stamp is about $0.50, the total cost is approximately 4 + 0.5 = $4.50.
Since she is buying about 10 stamps, the total cost is approximately 10 × 0.49 = $4.90.
Since each stamp is about $0.50, the total cost is approximately 4 × 0.5 = $2.00.
Since she is buying about 10 stamps, the total cost is approximately 10 + 0.49 = $10.49.
Answers
The answer of the given question based on the word problem of multiplication is , option (c) Since each stamp is about $0.50, the total cost is approximately 4 × 0.5 = $2.00.
What is Total cost?Total cost refers to the complete amount of money required to purchase or produce a given quantity of goods or services. It includes all the expenses involved in the production or purchase of the product or service, like materials, labor, and overhead costs, as well as any other additional expenses like taxes or shipping fees. Total cost is an important concept in economics and accounting as it helps businesses and individuals to determine the profitability of a product or service and make informed decisions about pricing and production.
The answer is: "Since each stamp is about $0.50, the total cost is approximately 4 × 0.5 = $2.00."
Rounding can be used to estimate the total cost of the stamps by approximating the cost of each stamp to the nearest 50 cents, which is $0.50. Therefore, the cost of four stamps can be estimated as 4 multiplied by 0.50, which is $2.00.

Answers
Answer:
Approach-avoidance
Step-by-step explanation:
The term that is being described in this question is known as Approach-avoidance. This occurs in many real-life scenarios where individuals really want something until they are met with the negative side of that goal and ultimately turn away because of those negative traits. One example that is widely used for this term is marriage. Marriage in itself is a very positive goal that many individuals strive for, but ultimately push away from it when they begin to see the negative aspects of it, even if the positive values overshadow the negative ones.

B. Alternate exterior angles are congruent.
C. Corresponding angles are congruent,
D. Consecutive interior angles are supplementary
Answers
Answer:
The statement which justifies Andrea's statement is "Corresponding angles are congruent" ⇒ C
Step-by-step explanation:
If two parallel lines intersected by a line, then there are some pair of angles are formed
Corresponding angles that are congruentAlternate interior angles that are congruentAlternate exterior angles that are congruentConsecutive interior angles that are supplementaryIn the given figure
∵ Lines l and m are parallel
∵ They are cut by transversal p
∵ ∠2 and ∠3 are in the corresponding position
→ By using the 1st rule above
∵ Corresponding angles are congruent
∴ ∠2 ≅ ∠3
∴ m∠3 = m∠2
∵ m∠2 = 40°
∴ m∠3 = 40°
The statement which justifies Andrea's statement is "Corresponding angles are congruent"

Answers
Step-by-step explanation:
It is given that,
The distance that Scott walks is a function of the time he spends walking. Scott can walk 1 half mile every 8 minutes.
Let y is the distance (in miles) and x is time (in minutes).
[tex]\dfrac{0.5}{8}=\dfrac{y}{x}\\\\\dfrac{x}{y}=16\\\\y=\dfrac{x}{16}[/tex]
The attached graph predicts the shape of the function. Hence, this is the required solution.

casey's den is 10feet longer than it is wide. If the den's area is 119 square feet, what are the dimensions of the room?
Answers
Answer:
The width is 7ft and the length is 17 ft
Step-by-step explanation:
Let w represent the width of the room and L represents the length of the den.
Given that:
caseys den is 10feet longer than it is wide
Then;
w + 10 = L ---- (1)
The area of the den = 119 ft²
Area = w × L
119 = w × L ---- (2)
From equation (1);
let w = L - 10.
Now we can replace the value of w into equation (2)
i.e.
(L - 10) × L = 119
L² - 10L - 119 = 0
(L + 7) ( L - 17) = 0
L + 7 = 0 or L - 17 = 0
L = - 7 ft or L = 17 ft
Recall that:
w = L - 10
w = -7 - 10 or w = 17 - 10
w = -17 or w = 7 ft
The area of the den can now be:
Area = -17 ft × - 7ft or 17ft × 7 ft
Area = 119 ft² or 119 ft²
Since it is ideal to use the positive integer,
Then the width is 7ft and the length is 17 ft
