hope this helps!

Answer:

negative 32 over 21

Step-by-step explanation:

\({ \rm{ \frac{4}{7} \div \frac{3}{ - 8} }} \\ \\ = { \rm{ \frac{4}{7} \times \frac{ - 8}{3} }} \\ \\ = { \rm{ - \frac{32}{21} }}\)

1. Write the equation in standard form:

2. Identify the coefficients a, b and c:

3. Substitute the values into the quadratic equation:

4. Solve the equation for x1 and x2:

Exact form and approximate form are the same for both solutions (x1 and x2):

Answer:

y = (1/2)x - 2

Step-by-step explanation:

To write x - 2y = 4 in slope intercept form, solve for y:

Subtract x from both sides so that -2y has been isolated on the left side:

-2y = 4 - x

Next, divide both sides by -2 to isolate y:

       4 - x

y = -----------

         -2

this simplifies to y = (1/2)x - 2

Answer:

So because the range is between 20 and 40, it can be noticed through counting.

5, 10, 15, 20, 25, 30, 35, 40

3, 6, 9, 12, 15, 18, 21, 24, 27, 30, 33, 36, 39

The number of balls in the box, just from the information by 5, is either ending in 1 (for example 21, 31) or 6 (26, 36)

From counting by 3 with that information, it would mean the number is most likely 26 balls, since there would be one left when Max reaches 25 counting by 5, and two left when he reaches 24 counting by 3.

Answer: a^+b^2=n^2

Step-by-step explanation:

The equation for triangle 2 will be: a² + b² = n².

What is Pythagorean theorem?

Pythagorean theorem states that for a right-angle triangle, the sum of the squares of the base and the height is equal to the square of the hypotenuse of that triangle.

Here, the angle between side: a and side: b is a right-angle.

Therefore, we can consider side: a as the height and side: b as the base of the triangle.

Therefore we can write as per the Pythagorean theorem:

(Base)² + (Height)² = (Hypotenuse)²

Hence, a² + b² = n²

Answer:

Step-by-step explanation

Frist, the area = ab = 30 m^2 and the perimeter = 2(a + b) = 34 m or a + b = 17 m (2). Solving (1) and (2), a = 15 m and b = 2 m. Since it is a rectangle, the dimensions are (all in m) so the answer is: 15, 2, 15, 2.

Answer:

THe kitchen is 8 by 10

Step-by-step explanation:

x = width

y = length

Area = xy = 80 m²

Perimeter = 2x + 2y = 36 m

2x = 36 - 2y

x = 18 - y   substitute into equation 1

(18 - y)(y) = 80

-y² + 18y - 80 = 0    find roots of y by factoring

y² - 18y + 80 = 0

(y - 8)(y - 10) = 0

y = 8, 10

Since xy = 80, then:

x = 80/10 = 8, or, x = 80/8 = 10

Now you have your dimensions: 8 and 10

To check the answers:

8 x 10 = 80 m²

2(8) + 2 (10) = 36 m

Step-by-step explanation:

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.

The correct interpretation of the P-value in this scenario is: "There is a 5.4% chance that a sample mean of 144 grams or greater will occur by chance if the true mean weight is 140 grams."

The P-value represents the probability of obtaining a sample mean as extreme as, or more extreme than, the observed value, assuming the null hypothesis is true. In this case, the null hypothesis would state that the mean weight of the Gala apples is 140 grams.

Since the P-value (0.054) is greater than the significance level (α = 0.05), it is not statistically significant at the 0.05 level. This means that we do not have strong evidence to reject the null hypothesis. However, the P-value is relatively close to the significance level, indicating that there is a moderate probability of observing a sample mean of 144 grams or greater if the true mean weight is actually 140 grams.

Therefore, we can interpret the P-value as indicating that there is a 5.4% chance that a sample mean of 144 grams or greater will occur by chance alone if the true mean weight of Gala apples is 140 grams.

Answer:

Katrina would need to buy 20 sweatshirts.

Step-by-step explanation:

The number of sweatshirts Katrina would need to order from  each company can be determined by forming the linear equation in two variables.

Given :

Let the number of sweatshirts orders from company MH Designs be 'x' and the number of sweatshirts orders from company Print Rich be 'y'.

So, the cost for ordering the sweatshirt from the company MH Design is:

\(21.50x = c\)

Now, the cost for ordering the sweatshirt from the company Print Rich is:

18y + 70 = c'

Given that the number of sweatshirts Katrina would need to order from  each company for the costs to be the same. So :

21.5x = 18y + 70

Now, put the value of x and y so, that in the above equation, both sides become equal.

If we use alpha as the criteria or critical value for the maximum probability of incorrectly rejecting the null hypothesis, then when the p-value is less than alpha, the null hypothesis is rejected. This means that there is strong evidence to suggest that the alternative hypothesis is true and that the data set supports this conclusion. Therefore, we can conclude that the null hypothesis is not supported by the data and that we can reject it.

  f(x) = x³ -4x² -5x +20

Step-by-step explanation:

If the function is to have rational coefficients, each complex or irrational square root must have a matching conjugate. That is, both -√5 and +√5 must be roots. If there is a root p, then there is a factor (x -p). The factored form of the minimal polynomial is ...

  f(x) = (x -4)(x +√5)(x -√5)

  = (x -4)(x² -5)

If a certain taxi driver charges a rate of r cents per person per mile. It would cost (3rx)/200 dollars .So the correct answer is option D.

If the taxi driver is charging r cents per person per mile, then the total cost for 3 people to travel x miles without the discount is 3rx cents. To give a 50% discount, the total cost would be reduced by 50%, or divided by 2.

Therefore, the total cost for 3 people to travel x miles with the 50% discount is (3rx)/2 cents. To convert this to dollars, we need to divide by 100 cents per dollar, giving us:

(3rx)/200 dollars.

It's important to pay attention to units and conversions when working with rates and percentages. In this case, we needed to convert from cents to dollars to get the final answer. Additionally, it's helpful to double-check the algebraic manipulation to ensure that the answer makes sense in the context of the problem.

a) The upper bound for the length of the rectangle is 245 mm.

b) The lower bound for the area of the rectangle is 3207.75 mm²

The possible range of values for the length of the rectangle is between 235 mm and 245 mm given that it is measured correct to 2 significant figure.

The highest possible value within this range, which is 245 mm is the upper bound.

Considering the possible values of the width that could be smaller than 13.7mm when rounded to one decimal place.

The actual value of the width could be anywhere in the range:

13.65mm ≤ actual width < 13.75mm

To find the lower bound for the area of the rectangle, we multiply the smallest possible value of the width and that of the length as follows:

Lower bound = 235 × 13.65mm

Lower bound for the area of the rectangle = 3207.75 mm²

Therefore, the upper bound for the length of the rectangle is 245 mm and the lower bound for the area of the rectangle is 3207.75 mm²

Answer:

The number of nickels and quarters in the bank are 87 and 56, respectively.

Step-by-step explanation:

Let's denote the number of nickels in the bank as "n" and the number of quarters as "q". Then we can set up a system of two equations based on the given information:

n + q = 143 (equation 1, representing the total number of coins)

0.05n + 0.25q = 18.35 (equation 2, representing the total value of the coins)

To solve this system, we can use substitution or elimination method. Let's use elimination method here:

Multiplying equation 1 by 0.05, we get:

0.05n + 0.05q = 7.15 (equation 3, obtained by multiplying equation 1 by 0.05)

Subtracting equation 3 from equation 2, we get:

0.2q = 11.2

Dividing both sides by 0.2, we get:

q = 56

Substituting this value of q into equation 1, we get:

n + 56 = 143

n = 87

Therefore, there are 87 nickels and 56 quarters in the bank.
