By changing the 'v' in 'cave' to 'n', we solve the clue: A curved stick, given by the word 'cane'. Although a concave mirror was mentioned, it doesn't fit in this context.
Explanation:The question asks you to change one letter in the word 'cave' to solve the clue: A curved stick. If we change the letter 'v' in 'cave' to 'n', we get the word 'cane'. A cane is typically curved at the top, resembling a stick. Although the reference to a concave mirror is interesting, it does not fit in this context as a concave mirror is a spherical mirror with its reflecting surface on the inner side of the sphere, forming a 'cave' shape. A useful tip to remember for distinguishing between concave and convex is: concave means caved in.

Grass can grow up to six inches in a week depending on temperature, humidity, and time of year. At this rate , how tall will grass grow in 24 days?
Grass can grow up to six inches in a week depending on temperature, humidity, and time of year
We have to calculate how tall will grass grow in 24 days
we know there are seven days in a week
so in one day grass can grow up to 6/7 inches
therefore we could say that grass can grow up to 24*6/7 inches
so the answer is 20.57 inches
so in 24 days grass can grow up to 20.57 inches
Grass can grow approximately 20.58 inches in 24 days.
Explanation:To calculate the height that grass will grow in 24 days, we need to find out how much it grows in 1 week, and then multiply that by the number of weeks in 24 days. If grass can grow up to six inches in a week, we can calculate the height it will grow in 24 days as follows:
Calculate the number of weeks in 24 days: 24 days ÷ 7 days/week = 3.43 weeks (rounded to the nearest hundredth).Multiply the growth per week (6 inches) by the number of weeks: 6 inches/week × 3.43 weeks = 20.58 inches.Therefore, grass will grow approximately 20.58 inches in 24 days.

Solution: The missing reason in Step 8 is substitution of [tex]x=c\cos (A)[/tex].
Explanation:
The given steps are used to prove the formula for law of cosines.
From step 5 it is noticed that our equation is
[tex]a^2=b^2-2bx+c^2[/tex] ..... (1)
From step 7 it is noticed that the value of [tex]x[/tex] is [tex]c\cos (A)[/tex].
So by substituting [tex]c\cos (A)[/tex] for [tex]x[/tex] in equation (1) we get the equation of step 8, i.e.,
[tex]a^2=b^2-2bc\cos (A)+c^2[/tex]
Hence, the missing reason in Step 8 is substitution of [tex]x=c\cos (A)[/tex].
The missing reason in Step 8 of the proof for the Law of Cosines is substitution, where x is replaced with cc cos(A) in the expression.
Explanation:The missing reason in Step 8 of the proof that shows how the Law of Cosines is derived, a2 = b2 + c2 – 2bc cos(A), is the substitution property. In Step 7, we established that c cos(A) is equal to x. Thus, for Step 8, when we replace x with cc cos(A) in the expression b2 – 2bx + c2, we effectively utilize substitution to arrive at the expression a2 = b2 – 2bccos(A) + c2.

In MNO NM=3 cm NO=4cm and MO=5 cm list the angels in order from smallest to largest
The triangle is a right triangle as the sides follow the Pythagorean theorem. The angles opposite the sides are 90° (largest), 53.13°, and 36.87° (smallest), listed from largest to smallest based on side lengths.
The student's question involves a triangle with sides of lengths 3 cm, 4 cm, and 5 cm and asks for the angles to be listed from smallest to largest. Since these side lengths satisfy the Pythagorean theorem (32 + 42 = 52), the triangle is a right triangle, with the right angle opposite the longest side, MO. Using the properties of a right triangle, we can determine that the smallest angle is opposite the shortest side, NM, and the next larger angle is opposite the intermediate side, NO.
To find the actual angle measurements, we would typically use trigonometric ratios such as sine, cosine, or tangent. However, since this is a 3-4-5 triangle, we already know that the angles are 90° for the right angle, and 36.87° and 53.13° for the other two angles, respectively. Thus, the angle opposite NM (3 cm) is the smallest, the angle opposite NO (4 cm) is larger, and the angle opposite MO (5 cm) is the largest, at 90 degrees.
The angle measurements in a right triangle will always follow this pattern based on the lengths of the sides, making it a straightforward matter to list them from smallest to largest.

Assume the $12,000 Treasury bill, 7% for 15 weeks. Calculate the effective rate of interest. (Use calendar year. Round your answer to the nearest hundredth percent.)
Answer:
7.25%
Step-by-step explanation:
You want the effective rate of interest on a $12,000 Treasury bill with a nominal interest rate of 7% and maturity in 15 weeks.
InterestThe Treasury computes the selling price of the bill by subtracting the interest from the face value. The interest is computed as "ordinary interest" using a 360-day year. 15 weeks is 105 days.
I = Prt
I = $12000·0.07·(105/360) = $245
Then the cost of the bill is $12,000 -245 = $11,755.
RateUsing the formula for the maturity value with a 365-day year, we have ...
A = P(1 +rt)
12000 = 11755(1 +r(105/365))
Solving for r gives ...
[tex]r=\left(\dfrac{12000}{11755}-1\right)\cdot\left(\dfrac{365}{105}\right)\approx0.0724514\approx\boxed{7.25\%}[/tex]
The effective rate of interest is about 7.25%.

76 is the correct answer
The price of the jersey before the mark-up = $76
What is percentage?"A number that can be expressed as a fraction of 100."
What is an equation?"It is a mathematical statement which consists of equal symbol between two algebraic expressions."
For given question,
A basketball jersey has been marked up by 25% and is now selling for $95.00
Let 'm' be the price of the jersey before the mark-up.
So, we get an equation,
⇒ m + (25 percent of m) = 95
25 percent of m
= [tex]\frac{25}{100}\times m[/tex]
= 0.25 m
so, the equation becomes,
⇒ m + 0.25 m = 95
⇒ 1.25 m = 95
⇒ m = 76
Therefore, the price of the jersey before the mark-up = $76

The area of a rectangular field is 8624 yd^2. If the length of the field is 98 yards, what is its width
The width of the rectangular field is 88 yards.
Explanation:To find the width of the rectangular field, we can use the formula for the area of a rectangle: Area = length x width.
In this case, the area is given as 8624 yd² and the length is given as 98 yards. So, we can rearrange the formula to solve for the width: width = Area / length.
Plugging in the values, we have width = 8624 yd² / 98 yds. Dividing these values gives us the width of the field: width = 88 yards.
Three consecutive odd integers whose sum is 243
Final answer:
The three consecutive odd integers whose sum is 243 are 79, 81, and 83. The integers were found using the algebraic expression for consecutive odd numbers and solving for the sum equal to 243.
Explanation:
To find three consecutive odd integers whose sum is 243, we can represent the first of these integers as 'n', the second as 'n + 2', and the third as 'n + 4', since each consecutive odd integer is 2 more than the previous one. The equation we would use to portray their sum is:
n + (n + 2) + (n + 4) = 243
Simplifying the equation, we combine like terms:
3n + 6 = 243
Next, we subtract 6 from both sides to isolate the 3n term:
3n = 243 - 6
3n = 237
Now we divide by 3 to solve for n:
n = 237 / 3
n = 79
The first odd integer is 79, the second odd integer is 79 + 2 = 81, and the third odd integer is 79 + 4 = 83.
Therefore, the three consecutive odd integers are 79, 81, and 83.
Find the radian measure of the central angle of a circle of radius r that intercepts an arc of length s. r = 2.7 meters, s = 4.32 meters
a. 1.6 radians
b. 0.37 radians
c. 3.5 radians
d. 1.35 radians
Answer:
The correct option is a.
Step-by-step explanation:
Given information: radius r =2.7 meters, arc length s = 4.32 meters.
The formula of arc length is
[tex]s=r\theta[/tex]
where, r is radius and θ is central angle in radians.
Using the above formula we get
[tex]4.32=2.7\times \theta[/tex]
Divide both sides by 2.7.
[tex]\frac{4.32}{2.7}=\theta[/tex]
[tex]1.6=\theta[/tex]
The value of the central angle is 1.6 radians. Therefore option a is correct.
