Answer:
28
Step-by-step explanation:
The total amount of cows is 48 and is split into 12 groups (7+5).
So 1 group is 48÷12=4
1 group=4
He owns 7 groups of Holstein cows.
So if 1 group is 4, 7 groups is 7x4=28.
28
The number of Holstein cows, if The ratio of Holstein and jersey cows is 7:5, and the Total number of cows is 48, is 28.
What is ratio?It is the contrast of two different quantities. For instance, if your father weighs 90 kg, and you weigh 30 kg, the weight ratio is 1:3. If b is not equal to 0, an ordered pair of numbers a and b, denoted as a / b, is a ratio. A proportion is an equation that equalizes two ratios.
Given:
The ratio of Holstein and jersey cows is 7:5,
Total number of cows = 48
Calculate the values as shown below,
Assume the number of Holstein cows is 7x
7x + 5x = 48
12x = 48
x = 4
Thus, the number of Holstein cows is 7 × 4 = 28

Answer:
0.477121=−log(3x+7)+0.30103
Step 1: Flip the equation.
−log(3x+7)+0.30103=0.477121
Step 2: Add -0.30103 to both sides.
−log(3x+7)+0.30103+−0.30103=0.477121+−0.30103
−log(3x+7)=0.176091

The table shows the cost of taking a rideshare trip. Which description correctly reflects the way the charges are calculated?
A)
The ride requires a $14 initial fee, plus 50 cents per mile driven
B
The ride requires a $14 initial fee, plus 51.90 per mile driven
The ride requires a $14 Initial fee, plus 52.15 per mile driven
D
The ride requires a 514 initial fee, plus 52.50 per mile driven
The table is an illustration of a linear function.
The description of the charges is: A) The ride requires a $14 initial fee, plus 50 cents per mile driven
The base fee is the charges, when the number of miles is 0
From the table;
y = $14, when x = 0
So, the base fee is $14
Next, we calculate the slope (m)
[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
From the table, we have:
[tex]m = \frac{16.5 - 14}{5-0}[/tex]
[tex]m = \frac{2.5}{5}[/tex]
[tex]m = 0.5[/tex]
The above means that:
The cost per mile is $0.5 (i.e. 50 cents)
Hence, the description of the charges is: A) The ride requires a $14 initial fee, plus 50 cents per mile driven

Prove the polynomial identity.
(4x^2−2)^2−(4x^2)^2=4(1−2x)(1+2x)
Drag and drop the lines of the proof in the correct order to complete the proof.
Answer:
(4x^2 - 2)^2 - (4x^2)^2 = 4(1 - 2x)(1 + 2x)
16x^4 - 16x^2 + 4 - 16x^4 = 4(1 - 2x)(1 + 2x)
4 - 16x^2 = 4(1 - 2x)(1 + 2x)
4(1 - 4x^2) = 4(1 - 2x)(1 + 2x)
4(1 - 2x^2)(1 + 2x) = 4(1 - 2x)(1 + 2x)

You are rolling artwork to ship so it fits perfectly in a cylindrical shipping tube. The volume of the shipping tube is

can ship and what formula can you use to calculate this height?
O 6 inches; height =
volume

O 24 inches, height
volume
3.14 x (radius)2
36 inches; height
volume
3.14 x radius
O 54 inches; height

3.14
The volume of a cylinder is found by using the formula V = pi x r^2 x h where r is the radius and h is the height.
Using the given volume and radius calculate the height:
169.56 = pi x 1.5^2 x h
169.56 = pi x 2.25 x h
169.56 = 7.065 x h
H = 169.56/7.065
H = 24 inches
The answer is the height is 24 inches

What is the Lcm of 22 and 33 using prime factorization
My answer would be 66
The LCM of 22 and 33, using prime factorization, is 66.
What is Number system?A number system is defined as a system of writing to express numbers.
We have to find LCM of 22 and 33 using prime factorization
Factor each term into prime factors
22 = 2 x 11
33 = 3 x 11
Identify all of the unique prime factors of these two numbers.
Finally, we can find the LCM by multiplying each of these prime factors raised to their highest power that appears in either of the two factorizations.
LCM(22, 33) = 2x 3 x 11
LCM(22, 33) = 66
Therefore, the LCM of 22 and 33, using prime factorization, is 66.

A scale drawing of an office space uses a scale of 1 in : 4 yd. The scale drawing has an area of 12 square inches.The area of the office space is ____ square yards
The scale factor of area of the drawing to the area of the office is the
square of the scale factor of the length of the drawing.
The area of the office space is 192 square yards.Reasons:
The given parameters are;
1 inch in the scale drawing = 4 yd. in actual dimension
4 yd. = 144 inches
Therefore;
1 inch in the scale drawing = 144 inches in actual dimension
The scale factor of length of the drawing, s = 1:144
The scale factor of area = s²
Therefore, we have;
[tex]\dfrac{Drawing \ area}{Actual \ area} =s^2[/tex]Therefore, we have;
[tex]\dfrac{Drawing \ area}{Actual \ area} =\dfrac{12}{A} = s^2 = \left( \dfrac{1}{144} \right)^2[/tex]Where;
A = The actual office space area
There fore;
12 × 144² = A × 1²
A = 12 × 144² = 248,832 in.²

line y = 3x - 6.
Answer:
y = 3x - 2
Step-by-step explanation:
Parallel lines have the same gradient in this case 3 is the gradient.
We will use the point (2,4) to form our own equation.
4 will be y, 3 will be m, 2 will be x
All we need is to find the C in the equation y=mx + c
4 = 3(2) + c
4 = 6 + c
C = -2
