15
Step-by-step explanation:Percentages represent a proportion of a number. There are 2 ways to find a percent of a whole number.
Multiple of 10
Since 30% is a multiple of 10%, there is a shortcut we can use. We can find 10% and then multiply by 3 in order to find 30%. First, find 10% of 50. Like always, 10% of any number is that number divided by 10 (move the decimal 1 place to the left).
50/5 = 10So, 10% of 50 is 5.0.
Then, to find 30%, multiply 5 by 3.
5*3 = 1530% of 50 is 15.
Multiplication
The more consistent method includes multiplication, this can be used with any percentage. To use this method we need to convert 30% to a decimal. To convert any percentage to a decimal divide by 100 (move the decimal 2 places to the left).
30% / 100 = 0.30Now, we can multiply this decimal by the whole number, 50. This will give us our desired answer.
0.30*50 = 15So, this once again shows that 30% of 50 is 15.

En una encuesta a 150 personas, se les pregunta sobre los deportes que ven por televisión
los fines de semana, ofreciendo como opciones fútbol, tenis y basquetbol. Los resultados
fueron los siguientes: 52 ven tenis; 54 ven básquetbol; 24 solo ven fútbol y tenis; 19 solo
ven fútbol y básquetbol; 23 ven tenis y básquetbol; 14 ven fútbol, tenis y básquetbol; 24
no ven deportes.
Teniendo en cuenta que el total de encuestados fue 150 personas, se puede calcular que el porcentaje de personas que solo ven tenis es 34.3%.
¿Cómo calcular el porcentaje de personas que solo ven tenis?
Para calcular el porcentaje de encuestados que solo ven tenis es necesario realizar la siguiente operación:
100 ÷ 150 = 0.660.66 × 52 = 34.3%De acuerdo con lo anterior, se puede inferir que el porcentaje de encuestados que solo ve tenis es el 34.3%.

What is the mean of the data set below?
15, 5, 16, 9, 14, 3, 4, 18, 10, 4
Answer:
Mean = Sum of Values ÷ Total number of Values
Step-by-step explanation:
= 15+5+16+9+14+3+4+18+10+4 ÷ 10
= 98 ÷ 10
= 9.8 (Decimal point moves 1 place to the left when divided by 10)

What are m∠1 and m∠2?
Answer:
B. <1 = 35, m<2 = 30
Step-by-step explanation:
To figure out m<1 I first need to figure out the other missing angle. A straight line is a 180 degree angle. Taking that information you can do 180 - 115. This means that the missing angle is 65 degrees. The interior angles of triangles always add up to 180.
80 + 65 = 145
180 - 145 = 35
<1 = 35
Repeat with the other side.
85 + 65 = 150
180 - 150 = 30
<2 = 30

The perimeter of a rectangle with length l and width w is 44 inches. The area of the rectangle is at most 120.
Which of the following statements is true?
A. If w 12 inches, then l 10 inches
B. If w 12 inches, then l 10 inches
C. If w 12 inches, then l 10 inches
D. If w 12 inches, then l 10 inches
The true statement about the rectangle is A. If w is 12 inches, then l is 10 inches
How to determine the true statement?The given parameters are:
Perimeter, P = 44Area = 120 (at most)The perimeter of a rectangle is:
P = 2(L + W)
So, we have:
2(L + W) = 44
Divide by 2
L + W = 22
The area is calculated as:
A = LW
This gives
LW = 120
Express 120 as 12 * 10 and 10 * 12
LW =12 * 10 or LW = 10 * 12
By comparison, we have:
L = 12 and W = 10 or L = 10 and W = 12
When these values are substituted in L + W = 22, we have:
10 + 12 = 22 and 12 + 10 =22
This means that the dimensions of the rectangle are 10 by 12 inches or 12 by 10 inches
Hence, the true statement is A. If w is 12 inches, then l is 10 inches

What is the y-coordinate of the point that divides the directed line segment from J to K into a ratio of 5:1? m Y 1 77](V₂ − V₁] + V₁ m+n -8 -5 0 6
The y-coordinate of the point that divides the directed line segment from J to K into a ratio of 5:1 is 0.
How to carry out division of line segments?
From the attached line segment graph, we see the coordinates as;
J (1, -10) and K (7, 2)
Let us assume that, point L divides the directed line segment from J to K into a ratio of 5:1.
From the properties of coordinate geometry we know that, the coordinates of point that divides the line joining (x₁, y₁), (x₂, y₂) in m:n, are;
[(mx₂ + nx₁)/(m + n)], [(my₂ + ny₁)/(m + n)]
Plugging in the relevant values gives;
[(5 * 7 + 1 * 1)/(5 + 1)], [(5 * 2 + 1 * -10)/(5 + 1)]
⇒ (6, 0)
Therefore, the y-coordinate of the point that divides the directed line segment from J to K into a ratio of 5:1 is 0.

Big Brothers, Inc. borrows $267,999 from the bank at 18.16 percent per year, compounded annually, to purchase new machinery. This loan is to be repaid in equal annual installments at the end of each year over the next 10 years. How much will each annual payment be?
Round the answer to two decimal places.
Based on the amount borrowed and the interest per year, Big Brothers, Inc will pay an annual payment of $59,973.15.
How much will Big Brothers, Inc. pay annually?This can be found by using the present value of an annuity formula because the annual payment will be constant and therefore like an annuity.
Formula is:
Present value of annuity = Annual payment x ( 1 - (1 + rate) ^ -number of periods) / rate
Solving gives:
267,999 = Amount x ( 1 - ( 1 + 18.16%)⁻¹⁰) / 18.16%
267,999 = Amount x 4.46865
Amount = 267,999 / 4.46865
= $59,973.15
