Answer:
54.16%
Step-by-step explanation:
The percentage of books that are some is 54.16 %
In order to find that answer you would have to calculate the total number of small books (26) over the total number of all of the books (48).
The equation would be 26/48=0.5416 however Multiply that answer by 100 and you would get 54.16% and if you want to round to the nearest whole number it would just be 54%

Find the exact area of a triangle with two sides that measure 6 yd and 2 yd with an included
angle of 10°
Answer:
1 yd^2
Step-by-step explanation
A=1/2(2)(6)Sin(10)
Final answer:
The area of a triangle with sides of 6 yd and 2 yd and an included angle of 10° is approximately 1.0439 square yards.
Explanation:
To find the exact area of a triangle with two sides measuring 6 yd and 2 yd and an included angle of 10°, you can use the formula for the area of a triangle when two sides and the included angle are known: A = ½ ab × sin(C), where a and b are the sides and C is the included angle.
The calculation will be: A = ½ × 6 yd × 2 yd × sin(10°). Using a calculator with the sine function set to degrees, we find that sin(10°) ≈ 0.17365. Therefore, the area A is approximately: A = ½ × 6 yd × 2 yd × 0.17365 ≈ 1.0439 yd².
Thus, the exact area of the given triangle is approximately 1.0439 square yards.
In a particular game, a spinner with four equally-sized sectors labeled 1, 3, 5, and 6 is spun twice. One turn is considered 2 spins of the spinner. If the sum of the spins is even, you move backward 6 spaces. Otherwise, you move forward 2 spaces. What is the mathematical expectation for the number of spaces moved in one turn? *
Answer:
3 spaces backwards, if you still need it.
Step-by-step explanation:
The mathematical expectation for the game described is -3 spaces, indicating that on average, a player will move 3 spaces backward per turn.
Expected Value Calculation:
To calculate the mathematical expectation for the number of spaces moved in one turn in the game described, we must consider all possible sums of the two spins and their outcomes. These outcomes are moving backward 6 spaces if the sum is even, or moving forward 2 spaces if the sum is odd. With a fair four-segment spinner that has equal likelihood for landing on numbers 1, 3, 5, and 6, we can calculate each possible sum and its associated probability.
Even sum outcomes: (1+3), (1+5), (3+5), (5+1), (3+1), (5+3), (1+6), (3+6), (5+6), and (6+6).Odd sum outcomes: (1+1), (3+3), (5+5), (6+1), (6+3), and (6+5).The probability of spinning an even sum is the number of even outcomes divided by the total number of outcomes (10/16). Similarly, the probability of spinning an odd sum is the number of odd outcomes divided by the total number of outcomes (6/16).
The expected value of moving spaces is therefore calculated by multiplying each sum outcome probability by the spaces moved for that outcome, and then summing these products:
Expected value = (Probability of even sum * -6 spaces) + (Probability of odd sum * 2 spaces)
= (10/16 * -6) + (6/16 * 2)
= (-60/16) + (12/16)
= (-48/16)
= -3
Thus, the mathematical expectation for the number of spaces moved in one turn is -3 spaces.

Answer:
0.25
Explanation: To divide a decimal number by a whole number, long divide as you would with two whole numbers, but put the decimal point in the answer at the same place it is at in the dividend. If it does not divide evenly, add a 0 to the end of the dividend and continue dividing until there is no remainder.
Which scenario is the BEST example of how the government would act in a mixed market economy?
The government requires a factory to produce surplus goods for the use of
the military.
The government stops a factory from producing imitations of an expensive
type of purse.
The government allows only two competitors to offer goods for sale on the
country's highways.
The government imposes a limit on the number of television sets that can
be exported annually.
In a mixed market economy, which typically combines elements of both market and government intervention, the BEST example is the government imposes a limit on the number of television sets that can be exported annually. Here option D is correct.
This scenario reflects a government intervention aimed at managing international trade and protecting domestic industries. By imposing export limits on television sets, the government can regulate the flow of goods, balance trade, and potentially safeguard local industries from excessive foreign competition.
This intervention allows for a controlled market environment while still allowing private enterprises to operate. Unlike the other options, this scenario demonstrates a strategic use of government intervention to achieve economic objectives without completely dominating the market or infringing on individual business operations.
It showcases a balance between free-market principles and government oversight, characteristic of a mixed market economy. Here option D is correct.
Complete question:
Which scenario is the BEST example of how the government would act in a mixed market economy?
A - The government requires a factory to produce surplus goods for the use of the military.
B - The government stops a factory from producing imitations of an expensive type of purse.

According to one survey, 25% of high school
students reported that they would not get summer
jobs. Predict how many of the 948 students at
Mohawk High School will not get summer jobs.
Answer:
237
Step-by-step explanation:
25/100 = x/948, simplify to get 1/4 = x/948
cross multiply and get 948=4x
swap the sides and get 4x=948
divide both sides by 4 and get x=237
in conclusion 237 students won't get summer jobs.
About 237 students at Mohawk High School are predicted not to get summer jobs based on applying the survey percentage of 25% to the total student population of 948.
Explanation:To predict how many students at Mohawk High School will not get summer jobs, we use the percentage from the survey and apply it to the total number of students at the school. According to the survey, 25% of high school students reported that they would not get summer jobs. Mohawk High School has a total of 948 students.
To find the number of students who will not get summer jobs, we perform the following calculation:
Percentage not working = 25%Total students = 948 studentsStudents not working = Total students × Percentage not working = 948 × 0.25Students not working = 237 studentsThus, we predict that about 237 students at Mohawk High School will not get summer jobs.
The perimeter of a rectangular Swimming pool is 70 yards.It's length Is 21 yards Which of the following Can be used to find the width? A. Width = ( 70 yd + 42 yd ) ÷ 2
B. Width = (70 yd + 42 yd ) ÷4
C. Width= (70 yd - 42 yd ) ÷4
D. Width= ( 70 yd - 42 yd ) ÷ 2
The width of the rectangular swimming pool is 14 yards.
Explanation:To find the width of the rectangular swimming pool, we can use the formula for the perimeter of a rectangle, which is P = 2(length + width). Given that the perimeter is 70 yards and the length is 21 yards, we can rearrange the formula to solve for the width:
P = 2(21 + w)
70 = 2(21 + w)
Divide both sides by 2:
35 = 21 + w
Subtract 21 from both sides:
14 = w
Therefore, the width of the swimming pool is 14 yards.

Step-by-step explanation:
A company mixes two kinds of cleansers to get a blend they sell for 59 cents a liter. One of the cleansers costs 50 cents per liter, and the other 80 cents per liter. How much of each kind should be mixed to get 2,000 liters of the blend?
Answer:
Cleanser that costs 50 cents is 1400 liters, Cleanser that costs 80 cents is 600 liters.
Step-by-step explanation:
We can solve this by using simultaneous equations:
Let us express the question in terms of equationsLet a be cleanser at 50 cents and let b be the cleanser at 80 cents.
Equation 1: 0.5a + 0.8b = 0.59(a+b)
Equation 2: a + b = 2000
From equation 2, a = 2000 - b (Let's call this equation 3)
2. Substituting equations 2 and 3 in Equation 1:
0.5a + 0.8b = 0.59(a+b)
0.5(2000 - b) + 0.8b = 0.59(2000)
1000 - 0.5b + 0.8b = 1180
0.3b = 180
b = 600
Substitute in equation 3:
a = 2000 - 600
a = 1400
As a note, I formed equation 1 because I know for a fact the cost per liter of a and b. I also know it is sold at 0.59 cents per liter. We are selling 2000 liters in this instance, therefore 0.59(2000) = 1180, which in this case is the selling price.
Final answer:
To create 2,000 liters of a cleanser blend sold at 59 cents per liter, the company should mix 800 liters of the 50-cent cleanser with 1,200 liters of the 80-cent cleanser, using a system of equations.
Explanation:
How to Mix Cleansers for a Desired Cost
To solve this problem, we need to set up a system of equations that reflects the cost and the quantity of the blend we want to obtain. Let's assign x to represent the amount in liters of the 50 cents per liter cleanser and y to represent the amount in liters of the 80 cents per liter cleanser.
Following the premise of the problem, we have two equations:
The total amount of the mixture should be 2,000 liters:
x + y = 2,000
The cost for the blend per liter is 59 cents, so the total cost for 2,000 liters would be 2,000 * $0.59. The sum of the individual costs of cleansers multiplied by their respective volumes should equal this total cost:
0.50x + 0.80y = 2,000 * $0.59
Solving this system of equations, we find that:
x = 800 liters of the 50 cents cleanser
y = 1,200 liters of the 80 cents cleanser
Thus, the company should mix 800 liters of the 50-cent cleanser with 1,200 liters of the 80-cent cleanser to obtain 2,000 liters of the blend sold for 59 cents a liter.

Step-by-step explanation:
(3x³)²·(25x⁶)·[tex]\frac{1}{2}[/tex] =9x⁵ · 25x⁶
Please mark me as the brainliest
Final answer:
The simplified expression equivalent to ((3x^3)^2 · (25x^6)^{1/2}) is 45x^9. This is obtained by applying exponent rules, such as power to a power and multiplying terms with the same base resulting in the addition of their exponents.
Explanation:
The expression in question is (3x^3)^2 · (25x^6)^{1/2}. To simplify this expression, we need to apply the exponent rules. When we raise a power to a power as in (a^m)^n, the exponents are multiplied, so (3x^3)^2 becomes 3^2 · x^{3×2}, which simplifies to 9x^6.
Next, taking the square root, which is the same as raising to the power of 1/2, we apply it to (25x^6)^{1/2}. The square root of 25 is 5, and raising x^6 to the 1/2 power gives x^{6×1/2}, or x^3. Therefore, we have 5x^3 as the simplified result of (25x^6)^{1/2}.
Multiplying these results together, we combine 9x^6 and 5x^3. When we multiply terms with the same base, we add their exponents, therefore we get 9×5 · x^{6+3}, resulting in 45x^9.

A square with diagonals is shown. The distance from one point to the middle point is 3. The length from the center point to another point is 3. What is the approximate side length of the square?
Answer:
4.24
Step-by-step explanation:
Since it is the midpoint, it means that the entire diagonal will measure twice, that is 3 * 2 = 6
To calculate the length of the sides, we can do it by means of Pythagoras, since it is a square a = b
c ^ 2 = a ^ 2 + b ^ 2
c ^ 2 = 2 * a ^ 2
6 ^ 2 = 2 * a ^ 2
a ^ 2 = 36/2
a = 4.24
therefore, it means that the sides of the square measure 4.24

Which equation is perpendicular to 3x - y = 9 and goes through the point (6,6)
Answer:
y = - [tex]\frac{1}{3}[/tex] x + 8
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Rearrange 3x - y = 9 into this form by subtracting 3x from both sides
- y = - 3x + 9 ( divide all terms by - 1 )
y = 3x - 9 ← in slope- intercept form
with slope m = 3
Given a line with slope m then the slope of a line perpendicular to it is
[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{3}[/tex], thus
y = - [tex]\frac{1}{3}[/tex] x + c ← is the partial equation
To find c substitute (6, 6) into the partial equation
6 = - 2 + c ⇒ c = 6 + 2 = 8
y = - [tex]\frac{1}{3}[/tex] x + 8 ← equation of perpendicular line
