A certain insect eats 1/8 gram of food each day.

How many days would the insect take 5 grams of the food?

We take

5 divided by 1/8 = 40 days

So, it would take the insect 40 days to eat 5 grams of the food.

Answer:40 days

Step-by-step explanation: first, how many days would it take for the insect to eat 1 gram of food? it would take 8 days so if it wants to eat 5 grams of food 8x5=40 so it would take 40 days for the insect to eat the food

An equation, in slope-intercept form, to represent the total cost, y, for x toppings on a jumbo pizza is y = 1.35 x + 15.

As per the data given:

A local restaurant charges $15 for a jumbo size cheese pizza.

Each of the additional topping costs $1.35.

Here we have to determine an equation, in the slope-intercept form, to represent the total cost, y, for x toppings on a jumbo pizza.

Considering y as the cost of pizza and x be the amount of topping added.

Cost of a pizza with toppings

y = 1.35 x + 15

The equation for the slope-intercept form is y = mx + c

m will be the slope of the equation.

Here, the slope of the equation is 1.35

The correct answer is option D: Chen read for less time because an hour a day for 7 days is equal to 210 minutes.

To determine the correct answer, we need to use the unitary method. This method involves converting the units of measurement into a common unit and then comparing them.

In this case, we need to convert hours into minutes to compare the reading time of Sierra and Chen.

An hour is equal to 60 minutes. Therefore, 1 hour a day for 7 days is equal to

=> 60 minutes * 7 days = 420 minutes.

However, we need to divide this number by 2 because Chen only read for half an hour a day. Hence, Chen read for 210 minutes

=> (420 minutes / 2).

Now that we have both the reading times in minutes, we can compare them. Sierra read for 220 minutes while Chen read for 210 minutes. As 220 > 210, it is clear that Sierra read for more time.

In conclusion, option D is the correct answer as Chen read for less time because an hour a day for 7 days is equal to 210 minutes. The unitary method is useful in comparing measurements with different units and it provides us with accurate results.

Complete Question:

The graph of a parabola is a u (or n) shaped curve obtained by the intersection of a cone and a plane which is parallel to the slant of the cone.

The x-intercepts are the point the graph intersects the x-axis, where the y-value is zero, y = 0. From the graph, the x-intercepts are;(-1, 0), and (3, 0)

The y-intercept is the point at which the graph intersects the y-axis, which is the point the x-value is 0, (x = 0). The graph indicates that the y-intercept is (0, 3)

The vertex of the parabolic graph is the highest (or lowest) point on the graph, therefore, from the graph in the question, the vertex point is; (1, 4)

The axis of symmetry is the line that divides the graph into two mirror halves, which is the line passing through the vertex and parallel to the y-axis. The axis of symmetry is therefore the line; x = 1

The domain is the set of the possible input values of the graph of the function, which is the set of the possinble x-values.

The graph indicates that the x-values can decrease and increase to -∞ and ∞. The domain is therefore; (-∞, ∞).

The region where the graph is increasing is fro x = -∞ to just before x = 1. The interval where the graph is increasing is therefore; (-∞, 1)

Similarly, the interval the graph is decreasing is; (4, ∞)

The graph is positive in the region above the x-axis. The interval over which the graph is positive is therefore between the x-intercepts, which is; (-1, 3)

The graph is negative in the region below the x-axis. The interval in which the graph is negative are; (-∞, 1), and (3, ∞)

Answer:

Below

Step-by-step explanation:

1)   The domain can be ANY value of 'x' except 'x' that cause the denominator to = 0    and it cannot be 'x' values that cause the denominator to be negative    as this is not allowed

so   x cannot be 5 or greater

       (-∞ , 5)   is the domain in interval notation

    or you could just write   x < 5      

2) you cannot have a negative square root so the domain would be all 'a'

       that the numerator would be 0 or greater (you CAN have a square root of '0' in the numerator)

             7-5a ≥ 0

               7 ≥ 5a

               7/5 ≥ a     or flipping it around    a ≤ 7/5

3) 15x^3y^2 + 10x^2 y - 20 x^2 y^3

For the triangle ABC the interior angles measures ∠A = 48°, ∠B = 82°, and ∠C = 50°.

What are triangles?

Triangles are a particular sort of polygon in geometry that have three sides and three vertices. Three straight sides make up the two-dimensional figure shown here. An example of a 3-sided polygon is a triangle. The total of a triangle's three angles equals 180 degrees. One plane completely encloses the triangle.

According to the angles of a triangle theorem, the sum of angles of a triangle is 180°.

The measure of ∠A = 4x.

The measure of ∠B = 7x - 2.

The measure of ∠C = 5x - 10.

The equation is -

∠A + ∠B + ∠C = 180°

Substitute the values into the equation -

4x + 7x - 2 + 5x - 10 = 180

Collect the like terms -

4x + 7x + 5x = 180 + 2 + 10

16x = 192

x = 192/16

x = 12°

So, the measure of ∠A = 4(12) = 48°.

The measure of ∠B = 7(12) - 2 = 82°

The measure of ∠B = 5(12) - 10 = 50°

The interior angles of the triangle are 48°, 82° and 50°.

Step-by-step explanation:

Answer:I hope this helps

Step-by-step explanation:

The end behavior of a function f describes the behavior of the graph of the function at the "ends" of the x-axis. In other words, the end behavior of a function describes the trend of the graph if we look to the right end of the x-axis (as x approaches +∞ ) and to the left end of the x-axis (as x approaches −∞ ).

End behavior refers to the appearance of a graph as it is followed indefinitely in either horizontal direction. Leading coefficient POSITIVE: both "ends" are UP. Leading coefficient NEGATIVE: both "ends" are DOWN. Leading coefficient POSITIVE: left end is DOWN and right end is UP.

If the degree is odd and the lead coefficient is positive, then the right end of the graph will point up and the left end will point down. If the degree is odd and the lead coefficient is negative, then the right end of the graph will point down and the left end will point up

In this particular study, Selection bias, Response bias, non response bias and Self-selection bias may exist.

There are several biases that may exist in the study:

1. Selection bias: By only calling people whose names were randomly sampled from the phone book, the study may not accurately represent the population of the state as a whole. Mobile phones and unlisted numbers, which may represent a significant portion of the population, are not included in phone books and therefore not included in the sample.

2. Response bias: The study only includes people who answered the phone when the senator's office called. This means that the sample only represents people who were available and willing to participate in the study. People who were not available or unwilling to participate may have different opinions, which would introduce a response bias.

3. Nonresponse bias: People who did not answer the phone when the senator's office called may have different opinions than those who answered. This nonresponse bias can result in an overestimation or underestimation of the true population values.

4. Self-selection bias: By only calling people who answered the phone, the study may only represent those who are interested in politics or are more likely to participate in political surveys. This self-selection bias can result in an overestimation or underestimation of the true population values.

These biases can lead to inaccurate results and conclusions. To reduce these biases, it's important to use a representative sample of the population and to make sure that the sample is selected in a way that minimizes bias

What is rotation?

In mathematics, a rotation is a transformation that spins a shape around an immovable object.

We are given that M is the midpoint of the diagonals.  

Since, M is the midpoint of the diagonals, so, VM = MQ and TM = MN.

Since T and N are equidistant from M, and the measure of ∠TMN = 180°, So, r(180°, M)(T) = N

Similarly, r(180°, M)(V) = Q  

We can rotate every point on TV in this same way.

So,  r(180°, M)(TV) = QN

Similarly, r(180°, M)(TQ) = VN  

Since, the rotations are rigid motions and they preserve distance, so, TV=QN and TQ=VN.

Hence, the measures of both pairs of opposite sides are equal in length.

One element within an experiment that allows you to increase the level of certainty in your results and account for random events is the use of a control group.

Level of certainty refers to the degree of confidence or assurance that one has in the accuracy of a particular result, decision, or conclusion. In scientific research, the level of certainty is often expressed as a probability or as a confidence interval, which provides a range of values that are expected to contain the true value with a certain degree of confidence. A higher level of certainty indicates a greater level of confidence that the result is correct, while a lower level of certainty indicates more uncertainty or ambiguity. Factors that can affect the level of certainty in an experiment or measurement include the quality of the data, the size of the sample, the accuracy of the methods used, and the presence of random or systematic errors.

By having a control group, you can compare the results of the experiment against a baseline and isolate any changes caused by the independent variable. Additionally, using a large sample size and repeating the experiment multiple times can also help increase the level of certainty and account for random events.

The value changes from 5/4 to 3/8 , then the percent of change from 5/4 to 3/8 is a 60% increase. So, the value change from 5/4 to 3/8 increases in percentage.

To determine whether the percent of change is an increase or a decrease, you need to calculate the difference between the old value and the new value as a percentage of the old value.

The old value is 5/4 and the new value is 3/8. To calculate the difference, you subtract the new value from the old value: 5/4 - 3/8 = 5/4 - 3/8 = 15/32.

Next, you need to express the difference as a percentage of the old value. To do this, you divide the difference by the old value and multiply by 100%. That gives you (15/32) / (5/4) * 100% = 60%.

Since the result is a positive percentage, it means that the percent of change is an increase. So, the percent of change from 5/4 to 3/8 is a 60% increase.
