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?
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

(1) Today, the temperature in New York is -1 degree and is expected to rise 3 degrees per day. It's 6
degrees in Alaska and expected to fall 1 degree every 2 days.
Answer:
New York: m=3, b=-1, y=3x-1
Alaska: m=-1/2, b=6, y=-1/2x+6
2 days; 5 degrees
Step-by-step explanation:
In each case, m is the rate of change, the number of degrees per day that the temperature is changing. 1 degree per 2 days is 1/2 degree per day.
In each case, b is the given initial temperature.
The equation is y = mx + b, for the values of m and b that you fill in.
New York
m = 3, b = -1, equation: y = 3x -1
Alaska
m = -1/2, b = 6, equation: y = -1/2x +6
__
The graphs can be plotted by plotting the initial point on the y-axis, then finding another point based on the slope.
For New York, another point will be 1 unit right and 3 units up, at (1, 2).
For Alaska, another point will be 2 units right a 1 unit down, at (2, 5).
The lines intersect at the point (2, 5) corresponding to 2 days, 5 degrees.

Answer:
7 [tex]\frac{1}{2}[/tex] miles
Step-by-step explanation:
The problem above is under the topic, "Subtracting Mixed Numbers with Similar Fractions."
In order to find the answer, you have to subtract the whole number parts first.
12-5 = 7
Then, you have to subtract the fractional parts. All you have to do is to get the difference of the numerators and copy the denominator.
7/8 - 3/8 = [tex]\frac{4}{8}[/tex]
Therefore, 12 [tex]\frac{7}{8}[/tex] - 5 [tex]\frac{3}{8}[/tex] = 7 [tex]\frac{4}{8}[/tex] miles
Let's simplify: 7 [tex]\frac{1}{2}[/tex] miles

In the figure, lines I and mare parallel lines cut by transversal p.
Andrea said that if m 2 2 = 40° then m 3 must also be equal to 40°. Which justifies Andrea's statement?
A
Alternate interior angles are congruent.
B. Alternate exterior angles are congruent.
C. Corresponding angles are congruent,
D. Consecutive interior angles are supplementary
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"

Three lines of crops in a garden form a triangular shape. Strawberries are planted in a 10 ft line and green beans are planted in an 18 ft line. If the third side, a line of pumpkins, makes an 68 degree angle with the strawberries, determine the length of the pumpkins.
Answer:
[tex]p = 19.18[/tex]
Step-by-step explanation:
This question is illustrated using the attachment and will be solved using cosine formula
[tex]a^2 = b^2 + c^2 - 2bcCosA[/tex]
Let the strawberry side be s, the Green beans be b and the pumpkins be p.
The cosine formula in this case is:
[tex]g^2 = s^2 + p^2 - 2spCosG[/tex]
Where
[tex]s = 10[/tex]
[tex]g = 18[/tex]
[tex]<G =68[/tex]
The equation becomes
[tex]18^2 = 10^2 + p^2 - 2 * 10 * p * Cos\ 68[/tex]
[tex]324 = 100 + p^2 - 20 * p * 0.375[/tex]
[tex]324 = 100 + p^2 - 7.5p[/tex]
Collect Like Terms
[tex]p^2 - 7.5p + 100 - 324 = 0[/tex]
[tex]p^2 - 7.5p - 224 = 0[/tex]
Using quadratic formula:
[tex]p = \frac{-b\±\sqrt{b^2-4ac}}{2a}[/tex]
Where
[tex]a = 1[/tex]
[tex]b = -7.5[/tex]
[tex]c = -224[/tex]
[tex]p = \frac{-(-7.5)\±\sqrt{(-7.5)^2-4*1*-224}}{2*1}[/tex]
[tex]p = \frac{7.5\±\sqrt{56.25+896}}{2}[/tex]
[tex]p = \frac{7.5\±\sqrt{952.25}}{2}[/tex]
[tex]p = \frac{7.5\± 30.86}{2}[/tex]
[tex]p = \frac{7.5 + 30.86}{2}[/tex] or [tex]p = \frac{7.5 - 30.86}{2}[/tex]
[tex]p = \frac{38.36}{2}[/tex] or [tex]p = \frac{-23.36}{2}[/tex]
[tex]p = 19.18[/tex] or [tex]p = -11.68[/tex]
But length can not be negative.
So:
[tex]p = 19.18[/tex]

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.
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.
