Total reduction over the given period is the product of the two numbers above:

The temperature on mountaintop was -10° and the temperature on the ground was 10°. The solution has been obtained by using the linear equation.

What is a linear equation?

One is the degree of the linear equation. It is obvious that there are no variables in linear equations with exponents greater than 1. The graph's equation results in a straight line.

We are given that the temperature on the mountaintop was 20° lower than temperature on the ground.

Let the temperature on the ground be 'x'.

So, temperature on the mountaintop = x - 20

Also, the temperature on a mountaintop and the temperature on the ground had opposite values.

So,

x = - (x - 20)

On solving this, we get

⇒x = -x + 20

⇒2x = 20

⇒x = 10°

So, x - 20 = 10 - 20 = -10°

Hence, the temperature on mountaintop was -10° and the temperature on the ground was 10°.

The triangle ∆MNO is similar to the triangle ∆M'N'O' hence, N'O' is equal to 4.5 inches and M'O' is equal to 6 inches

Similar triangles are two triangles that have the same shape, but not necessarily the same size. This means that corresponding angles of the two triangles are equal, and corresponding sides are in proportion.

We solve for N'O' and M'O' with the proportion equation as follows:

NO/N'O' = MN/M'N'

3in/N'O' = 2/3

N'O' = (3 × 3in)2 {cross multiplication}

N'O' = 4.5 in

MO/M'O' = MN/M'N'

4in/M'O' = 2/3

M'O' = (3 × 4in)2 {cross multiplication}

M'O' = 6 in

Therefore, the similar triangles ∆MNO and ∆M'N'O' have the value of N'O' equal to 4.5 inches and M'O' is equal to 6 inches

The combination that is produced contains 57.5% corn.. It is calculated by taking the weighted average of the corn content in the two bags, accounting for their respective weights.

(50% x 20 lbs) + (65% x 30 lbs)

= 1750 lbs + 1950 lbs

= 3700 lbs

3700 lbs/50 lbs

= 57.5%

The concentration of corn in the resulting mixture is 57.5%. This is calculated by taking the weighted average of the corn content in the two bags. The first bag, containing 20 pounds of calf starter mix, contains 50% corn. The second bag, containing 30 pounds, contains 65% corn. To calculate the concentration of corn in the mixture, the percentage of corn in each bag is multiplied by its respective weight, and the sums of these two products are then divided by the sum of the two weights. In this case, (50% x 20 lbs) + (65% x 30 lbs) = 1750 lbs + 1950 lbs = 3700 lbs. The resulting concentration of corn in the mixture is 3700 lbs/50 lbs = 57.5%.

The correct option is 0.9098. The probability that at least 16 Californians prefer hot weather over cold weather is 0.9098.

According to a survey, 67.5% of Californians prefer hot weather over cold weather. Let X = number of Californians in a sample of 19 who prefer hot weather over cold weather. Then, the probability that at least 16 Californians prefer hot weather over cold weather can be calculated by using the cumulative binomial probability formula. Let X = the number of Californians in a sample of 19 who prefer hot weather over cold weather.

The formula for calculating the cumulative binomial probability is: P(X≥k) = ∑i=kn P(X=i)

In this example, k = 16, n = 19, and P(X=i) = 0.675

Therefore, P(X≥16) = ∑i=1619 P(X=i) = 0.9098

The measures of angles are m∠A = 80°, m∠B = 50°, and m∠C = 50°, concluding that the triangle is an isosceles triangle.

Based on the given information, we can start by using the fact that the angles in a triangle sum to 180 degrees. Let's label the unknown angles as m∠A, m∠B, and m∠C:

m∠A + m∠B + m∠C = 180

We also know that m∠1 = m∠2, which means that triangle ABD is similar to triangle CBD by the Angle-Angle (AA) similarity theorem. This implies that the ratios of corresponding sides in these triangles are equal:

AB/BD = BD/DC

Since BD = DC, we have AB = DC.

Therefore, triangle ABC is isosceles with AB = AC. This means that m∠B = m∠C.

Now let's use the given information that BD = DC and m∠BDC = 100° to find the measure of m∠B. We can draw the perpendicular bisector of BC to point D, which will bisect angle BDC into two equal angles of measure x degrees.

Since triangle BDC is isosceles, we know that:

m∠DBC = m∠DCB

= (180 - m∠BDC)/2

= 40°.

Therefore, m∠B = m∠DBC + m∠DCB = 40° + x.

Now we can use the fact that the angles in triangle ABC sum to 180 degrees to solve for m∠A:

m∠A + m∠B + m∠C = 180

m∠A + 2m∠B = 180 (since m∠B = m∠C)

m∠A + 2(40° + x) = 180 (since m∠B = 40° + x)

m∠A + 80° + 2x = 180

m∠A = 100° - 2x

We also know that m∠BDC = 100°, so m∠DBC = m∠DCB = (180 - m∠BDC)/2 = 40°. Therefore, we can write:

m∠A + m∠B + m∠C = 180

m∠A + 2m∠B = 180 (since m∠B = m∠C)

m∠A + 2(40° + x) = 180 (since m∠B = 40° + x)

m∠A + 80° + 2x = 180

m∠A = 100° - 2x

Now we can solve for x by using the fact that m∠A, m∠B, and m∠C must be positive:

m∠A > 0, m∠B > 0, m∠C > 0

100° - 2x > 0

x < 50°

Therefore, the possible values of x are 10°, 20°, 30°, 40°, and 49°. We can use these values to find the measures of m∠A, m∠B, and m∠C:

If x = 10°, then m∠A = 80°, m∠B = 50°, and m∠C = 50°.

Step-by-step explanation:

yes it is a linear factor, my sister told me the answser

(not sure):

Explanation:

We simplify the square root of 64 to get 8

\(\sqrt{64} = \sqrt{8^2} = 8\)

Then we'll have the plus minus out front to say

\(x = \pm \sqrt{64} = \pm 8\)

That breaks down into x = 8 or x = -8

As a check

x^2 = (8)^2 = 8*8 = 64

x^2 = (-8)^2 = (-8)*(-8) = 64

Both values lead to 64 when squaring.
