Answer:

x=5/3

Step-by-step explanation:

The lengths in the left side are proportional to the ones in the right side, with that we know that x = 10.

The lengths in the left side and the ones in the right side are proportional, such that the scale is k.

Then we can write:

21*k = 27

(x - 3)*k = (x - 1)

With the first equation, we can find the value of k, then we will get.

k = 27/21

Replacing that in the second equation we will get:

(x - 3)*27/21 = (x - 1)

Now we can solve this.

(x - 3)*27 = 21*(x - 1)

Now we can solve this for x.

27x - 81 = 21x - 21

27x - 21x = 81 - 21

6x = 60

x = 60/6 = 10

x = 10

The answer of the given question based on the sum of the two angles is ,the answer is  5x + 25° degrees.

The distributive property is fundamental property of arithmetic and algebra that allows us to  multiply single term or sum by factor. The property states that:

a×(b+c)=a×b+a×c

In words, this means that the when number or variable (a) is multiplied by  sum of two other numbers or variables (b + c), it is  same as  multiplying a by each term of  sum (b and c) and then adding two products. The distributive property can  be used in reverse to factor out common factor from  sum of terms.

The sum of these two angles is:

2x° + (3x + 25)°

= 2x° + 3x° + 25° (using the distributive property of multiplication)

= 5x° + 25°

Therefore, the sum of the two angles is 5x + 25° degrees.

The time it takes for the bacteria to reach 1,000,000 is given as follows:

t = 164.5 minutes.

The number of bacteria after t minutes is given by the exponential function presented as follows:

P(t) = 1000e^(0.042t).

The population will reach 1,000,000 when:

P(t) = 1,000,000.

Hence the time needed is obtained solving the equation as follows:

1,000,000 = 1000e^(0.042t).

e^(0.042t) = 1,000,000/1,000

e^(0.042t) = 1000.

The inverse operation regarding the exponent e is the natural logarithm, hence we can isolate t as follows:

0.042t = ln(1000)

t = ln(1000)/0.042

Answer: The factor that does not influence interest rates in regards to loans is "Number of Children". The other options, collateral, credit history, and inflation, can all have an impact on interest rates. Collateral refers to the assets that a borrower pledges as security for the loan, and the value of these assets can affect the interest rate. Credit history refers to a borrower's past performance in repaying debts, which can affect their perceived risk and therefore the interest rate they are offered. Inflation refers to the general increase in prices over time, and can affect interest rates because lenders will want to charge a rate that compensates them for the loss of purchasing power due to inflation. However, the number of children a borrower has is not a factor that lenders consider when setting interest rates.

Step-by-step explanation:

The solution to the given system of equations is x = 2.67 and y = 5.

The given system of equations can be solved by adding the two equations together.

The child will get about 281.3 cubic centimeters more ice cream in the cylindrical-shaped cup than in the cone-shaped cup.

Volume is an important concept in many areas of science and engineering, including physics, chemistry, and materials science. It is also used in everyday life, such as in calculating the amount of liquid that can be held in a container, or the amount of space that is needed to store a set of objects.

To determine which cup shape holds more ice cream, we need to compare their volumes. The formula for the volume of a cone is (1/3)πr²h, where r is the radius of the circular base and h is the height of the cone. The formula for the volume of a cylinder is πr²h, where r is the radius of the circular base and h is the height of the cylinder.

First, let's find the volume of the cone-shaped cup:

radius = diameter/2 = 8/2 = 4 cm

height = 12 cm

volume = (1/3)πr²h

volume = (1/3)π(4 cm)²(12 cm)

volume ≈ 201.1 cm³

Next, let's find the volume of the cylindrical-shaped cup:

radius = diameter/2 = 8/2 = 4 cm

height = 12 cm

volume = πr²h

volume = π(4 cm)²(12 cm)

volume ≈ 482.4 cm³

The cylindrical-shaped cup has a larger volume, so the child should choose the cylindrical-shaped cup to get the most ice cream.

To find out how much more ice cream the cylindrical-shaped cup holds, we can subtract the volume of the cone-shaped cup from the volume of the cylindrical-shaped cup:

482.4 cm³ - 201.1 cm³ ≈ 281.3 cm³

Therefore, the child will get about 281.3 cubic centimeters more ice cream in the cylindrical-shaped cup than in the cone-shaped cup.

Median (Q2) = (16 + 18) / 2 = 17

Lower half: 10, 11, 12, 15, 16

Median (Q1) = (11 + 12) / 2 = 11.5

Upper half: 18, 20, 22, 25, 30

Median (Q3) = (22 + 25) / 2 = 23.5

This is a horizontal line passing through the point (-9, -3).

Slope is a measure of how steep a line is. It is defined as the ratio of the change in the y-coordinates of two points on a line to the change in the x-coordinates of those same points. In other words, slope is the amount by which the y-coordinate changes when the x-coordinate changes by 1 unit.

Since the given line is vertical, its slope is undefined. The slope of a line perpendicular to it is zero. Therefore, the slope of the graph of f is zero.

We can use the point-slope form of a linear equation to write the equation of the line passing through the point (-9, -3) with a slope of zero:

y - (-3) = 0(x - (-9))

Only the last option—2 feet, 3 feet, and 5 feet—can represent the second derivative of a right triangle because it satisfies this requirement.
