In response to very high demand, a basketball jersey has been marked up by 25% and is now selling for $95.00. How much was the jersey before the mark-up?
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

Find the area enclosed between f(x)=0.3x2+7 and g(x)=x from x=−4 to x=8.
To find the area enclosed between two functions, we calculate the definite integral of the absolute difference between the functions over the given interval. The area is equal to the integral of ∣f(x) - g(x)∣, split into two parts where g(x) ≥ f(x) and g(x) < f(x), then added together. The enclosed area for the given functions is 82.26 square units.
Explanation:To find the area enclosed between the functions f(x) = 0.3x^2+7 and g(x) = x from x = -4 to x = 8, we need to calculate the definite integral of the absolute difference between the two functions over the given interval.
The area is equal to the integral of ∣f(x) - g(x)∣ from x = -4 to x = 8. We can split the integral into two parts where g(x) ≥ f(x) and g(x) < f(x), then evaluate each separately. Finally, we add the two areas together.
After evaluating the integrals, we find that the area enclosed between the two functions is 82.26 square units.

There were 48 blue, 48 green and 48 yellow crayons. Also there were 72 red crayons and 120 colored pictures. What is the largest number of identical sets can be made of these crayons and pictures?
24 is the largest number of identical sets can be made of these crayons and pictures
What is Number system?A number system is defined as a system of writing to express numbers.
To find out the largest number of identical sets that can be made, we need to determine the common factors of the total number of crayons and pictures.
The prime factorization of 48 is 2 x 2 x 2 x 2 x 3, and since all three colors have the same number of crayons, we can say that there are 48 x 3 = 144 crayons in total.
The prime factorization of 72 is 2 x 2 x 2 x 3 x 3, and the prime factorization of 120 is 2 x 2 x 2 x 3 x 5.
The common factors of 144, 72, and 120 are 2 x 2 x 2 x 3 = 24. This means that we can make 24 identical sets.

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.

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.

An acute angle θ is in a right triangle with cos θ =2/3 . What is the value of sec θ?
Final answer:
The secant of an angle is the reciprocal of its cosine. Given cos θ = 2/3 for an acute angle in a right triangle, the sec θ equals 3/2.
Explanation:
In the context of trigonometry, the secant (sec) of an angle is the reciprocal of the cosine (cos) of that angle.
Given that cos θ = 2/3 for an acute angle in a right triangle, we can find the value of sec θ by taking the reciprocal of the cosine value. Hence, the value of sec θ is simply the reciprocal of 2/3, which is 3/2.

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%.

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.
