If a triangle has angle measurements of 15 degrees and 90 degrees what is the measure of the third angle

In order to subtract mixed numbers, you need to make sure the fractions have the same denominator, subtract the numerators, subtract the whole numbers, and then combine the results.

When you subtract mixed numbers, you need to remember to subtract both the whole numbers and the fractions separately. The first step is to make sure that the fractions have the same denominator. Once the fractions have the same denominator, you can subtract the numerators and keep the denominator the same. After that, you can subtract the whole numbers.

Step 1: Make sure the fractions have the same denominator.

Step 2: Subtract the fractions.

Now that the fractions have the same denominator, we can subtract the numerators and keep the denominator the same:

Step 3: Subtract the whole numbers.

Now we can subtract the whole numbers:

Step 4: Combine the result.

Finally, we'll combine the result of the fraction and whole number:

Answer:

c- 4 x 10^7

Step-by-step explanation:

for scientific notation, the first number can not be greater than 9

so you have to split your number into a decimal

37,250,000

3.7250000

so the first part of your equation is 4 because the 7 rounds up the 3

then, there are 7 digits after the decimal, so that is your exponent

it is also positive.

so your final answer is

4 x 10^7  :)

The transformation of System A into System B is:

Equation [A2]+ Equation [A 1] → Equation [B 1]"

The correct answer choice is option D

How can we transform System A into System B?

To transform System A into System B as 1 × Equation [A2] + Equation [A1]→ Equation [B1] and 1 × Equation [A2] → Equation [B2].

System A:

-3x + 4y = -23 [A1]

7x - 2y = -5 [A2]

Multiply equation [A2] by 2

14x - 4y = -10

Add the equation to equation [A1]

14x - 4y = -10

-3x + 4y = -23 [A1]

11x = -33 [B1]

Multiply equation [A2] by 1

7x - 2y = -5 ....[B2]

So therefore, it can be deduced from the step-by-step explanation above that System A is ultimately transformed into System B as 1 × Equation [A2] + Equation [A1]→ Equation [B1] and 1 × Equation [A2] → Equation [B2].

Answer:

plane CGF and ABC

Step-by-step explanation:

Yes, if aa is a square matrix and \det(ab^2)=5det(ab 2 )=5, then bb is invertible. This is because if \det(ab^2)=5det(ab 2 )=5, then the determinant of ab is not zero, which means that ab is invertible. Since ab is invertible, this implies that b is also invertible, because if b was not invertible, then ab would not be invertible.

Therefore, bb is invertible as well. Given that A is a square matrix and det(AB^2) = 5, we need to determine if B is invertible. Recall that a matrix is invertible if its determinant is non-zero.Let's first look at the determinant properties:

1. det(AB) = det(A) * det(B)
2. det(B^2) = det(B) * det(B)

Now let's consider the given equation:

det(AB^2) = 5

Substitute the properties mentioned above:

det(A) * det(B) * det(B) = 5

This equation shows that det(A) * det(B)^2 = 5.

Since the determinant of the product is not equal to zero, it means that neither det(A) nor det(B)^2 is equal to zero. Therefore, det(B) must be non-zero as well, because if it were zero, det(B)^2 would also be zero.As a result, since det(B) is non-zero, we can conclude that B is invertible.

How does cellular respiration help maintain homeostasis in animals?

Answer: Cellular respiration helps animals maintain homeostasis by breaking down glucose to produce ATP, which is the energy currency of the cell. ATP is necessary for many cellular processes that help maintain homeostasis such as active transport and protein synthesis.

Explain why cells separate and expel waste.

Answer: Cells separate and expel waste to prevent the accumulation of toxic substances that can disrupt cellular function and lead to disease. The waste products are transported out of the cell and into the bloodstream where they are filtered and excreted by organs such as the kidneys.

Why do cells in organisms such as animals reproduce?

Answer: Cells in organisms such as animals reproduce to replace damaged or dying cells, and to enable growth and development. Reproduction ensures that the organism maintains the proper balance of cells and that there is enough tissue to perform necessary functions.

Explain how plant cells use photosynthesis to maintain homeostasis?

Answer: Plant cells use photosynthesis to maintain homeostasis by converting light energy into chemical energy in the form of glucose. This glucose is then used to produce ATP, which is necessary for cellular processes such as active transport and protein synthesis. Additionally, plants use photosynthesis to produce oxygen, which is necessary for respiration.

Step-by-step explanation:

The area under the standard normal curve is approximately 0.1368 for (b) and 0.2197 for (c). Remember that in case (a), where the Z-values are the same, the area between them is 0.

To determine the area under the standard normal curve between specific Z-values, we can use a standard normal distribution table or a calculator with a built-in cumulative distribution function (CDF) for the standard normal distribution. Here are the calculations for each case:

(a) Z = -1.78 to Z = -1.78:

Since the two Z-values are the same, the area under the curve between them is 0. This means there is no area between these Z-values.

(b) Z = 0.35 to Z = 0:

To find the area under the curve between these two Z-values, we need to calculate the cumulative probability at each Z-value and subtract the smaller value from the larger one. Using a standard normal distribution table or a calculator, we find:

For Z = 0.35, the cumulative probability is 0.6368.

For Z = 0, the cumulative probability is 0.5000.

Therefore, the area between Z = 0.35 and Z = 0 is:

0.6368 - 0.5000 = 0.1368

(c) Z = -0.63 to Z = -0.04:

Similarly, we calculate the cumulative probability for each Z-value and find the difference between them:

For Z = -0.63, the cumulative probability is 0.2643.

For Z = -0.04, the cumulative probability is 0.4840.

The area between Z = -0.63 and Z = -0.04 is:

0.4840 - 0.2643 = 0.2197

The complete question is:

Determine the area under the standard normal curve that lies between (a) Z=-1.78 and Z=-1.78, (b) Z=0.35 and Z=0, and (c) Z=-0.63 and Z=-0.04

When a single card is randomly drawn from a standard deck of 52 playing cards, the odds in favor of the card being a 3, 4, 5, 6, or 7 can be calculated by considering the total number of these cards and the total number of cards in the deck.

In a standard deck, there are four suits (hearts, diamonds, clubs, and spades), each containing one card of each rank (from Ace to King). Therefore, there is one 3, 4, 5, 6, and 7 in each suit, which results in a total of 4 cards for each rank (3s, 4s, 5s, 6s, and 7s). As there are five ranks in question, there are 4 x 5 = 20 cards that are either a 3, 4, 5, 6, or 7.

To find the odds in favor of drawing one of these cards, we'll divide the number of favorable outcomes (20) by the total number of possible outcomes (52). So, the odds in favor are:

20 (favorable outcomes) / 52 (total outcomes) = 5/13

Therefore, the odds in favor of drawing a 3, 4, 5, 6, or 7 from a standard deck of cards are 5/13.

Therefore, -3|x| + 2x - 1 = -26 when x=-5.

The number of tourists in a coastal city increased from 299 thousand people in 1986 to 517 thousand people in 1997. Find the percent increase.

Percentage increase is a method of determining an increase in value, which is calculated as follows:
Percent Increase = (New Value − Old Value) / Old Value × 100%.
To determine the percent increase in the number of tourists, we use the above formula.Substituting the given values in the formula,
Percent Increase = (New Value − Old Value) / Old Value × 100%
Percent Increase = (517,000 - 299,000) / 299,000 × 100%
Percent Increase = 218,000 / 299,000 × 100
%Percent Increase = 73%

y = [ 8 ]x + [ -9 ]

Answer:

x = 7

Step-by-step explanation:

In a parallelogram the opposite angles are congruent, then

14x + 8 = 106 ( subtract 8 from both sides )

14x = 98 ( divide both sides by 14 )

x = 7

\(x=7\)

Step-by-step explanation:

\(m∠ X= m∠V\)

\(14x + 8 = 106\)

\(14x = 106 - 8\)

\(14x = 98\)

\( \frac{14x}{14} = \frac{98}{14} \)

\(x = 7\)

to be sure

\(14x + 8 { = }^{?} 106\)

\(14 \times 7 + 8 { = }^{?} 106\)

\(98 + 8 { = }^{?} 106\)

\(106 = 106\)
