Can you Answer the question

Answers

Answer 1

A line forms a straight angle, which measures 180 degrees. Since you know that b and c are lines, and that angles 1 and 3 collectively measure 314, you can figure out the measure of angle 2 (and angle 4) by setting up an equation like the one that follows:

180 = 314/2 + x
180 = 157 + x
23 = x

Answer:
Angle 2 = 23 degrees

Listed are the distances traveled by four cars and the time it took each car to cover that distance. Identify which cars traveled at the same speed.

Answers

Where is the list will all of this the list is needed

Car 1 and car 3 have the same speed.

What is division?

Math operations include division as one of its types. This technique involves splitting the phrases or numbers into the same amount of components.

To find which cars traveled at the same speed, we need to calculate the speed of each car. We can do this by dividing the distance traveled by the time it took to cover that distance.

For example, car 1 traveled 140 miles in 2 hours, so its speed was:

Speed of Car 1 = Distance of Car 1 / Time of Car 1 = 140/2 = 70 miles per hour.

Similarly, we can calculate the speed of each car using the given data. When we do this, we get:

Speed of Car 1 = 70 mph

Speed of Car 2 = 80 mph

Speed of Car 3 = 70 mph

Speed of Car 4 = 50 mph

We can see that Car 1 and Car 3 traveled at the same speed, which was 70 miles per hour. Therefore, the answer is that Cars 1 and 3 traveled at the same speed.

The ordered pairs (1, 3), (2, 6), (3, 9), (4, 12) and (5, 15) represent a function. What is a rule that represents this function? a: y=x^3 b: y= 3^x c: y=3x d: y= x+3

Answers

In case you don't know your times-3 numbers well enough to recognize the answer right away, you can check the second data point.
.. a. 2^3 = 8 ≠ 6
.. b. 3^2 = 9 ≠ 6
.. c. 3*2 = 6
.. d. 2 +3 = 5 ≠ 6

Only selection C makes sense.

Answer: option c: y = 3x

Justification:

All the ordered pairs meet that the second number of the pair equal 3 times the first number of the pair:

Here is the proof:

Pair         first number times 3   second number of the pair

(1, 3)         3 * 1 = 3                         3   => check

(2,6)          2 * 3 = 6                         6   => check

(3,9)          3 * 3 = 9                         9   => check

(4,12)        3 * 4 = 12                      12 => check

(5, 15)       3 * 5 = 15                      15 => check.

Terrance has one fewer sibling than Casey. Kolbie has three more siblings than Terrance

Answers

if Terrance has x siblings then Casey has x+1silblings and Kolbie has x+3siblings. what are you trying to solve??

Final answer:

By setting up simple equations based on the given statements, we can determine the relative number of siblings that Terrance, Casey, and Kolbie have.

Explanation:

Based on the provided statements, we can set up a system of simple algebraic equations to solve for the number of siblings each person has. Let's assume Casey has C siblings. According to the given information:

Terrance has one fewer sibling than Casey, which can be represented as T = C - 1.

Kolbie has three more siblings than Terrance, which can be represented as K = T + 3.

Therefore, Kolbie's equation becomes K = (C - 1) + 3 or K = C + 2 after simplifying. Through these relationships, we can understand the relative number of siblings each individual has.

Betty saves 3 times as much as Ann. Charles saves 390 less than Ann. If Betty saves 1,330 more than Charles, how much does Charles save

Answers

To answer this, I set up a system of equations for each sentence mentioned (B=3A for Betty, A - 390 for Ann, and B = (A - 390) + 1330 to show the relationship between Betty and Charles's amounts. The way to answer this is to replace the B with the 3A that represents Betty's amount. This creates 3A= (A-390) + 1330. By having only one variable you can then solve the equation to find Ann's amount. If you know Ann's amount, you can figure out Charles' amount. To solve the equation add 1330 and -390 which is the same as subtracting 390 from 1330. This leaves you with 3A= A + 940. Subtract 1A from both sides, to leave you with 2A = 940. Solve for a by dividing both sides by 2. This leaves you with A= 470. Take this value of a and substitute it in to Charles's equation which is C = A - 390. 470 - 390 equals 80. This is Charles' amount saved.

This cylindrical fish tank has a height of 36 inches and a diameter of 30 inches. What is the volume of the fish tank?

Answers

The formula for the volume of a cylinder is:
area of cross-section x the height.

First lets work out the area of the cross-section. Since the cross-section is a circle, we use the formula π x r²

Halve the the diameter to get the radius, so we can use the formula:
30 / 2 =15

Area of cross-section
π x 15² = 706.8583471 inches²

Now that we know the area of the cross-section, we multiply this by the height to get the volume.

706.8583471 x 36 = 25446.90049
= 25446.90 (2dp)

So the volume of the cylindrical fish tank is 25446.90

The volume of the cylindrical fish tank is 25446.90 inches cube.

What is the volume of a right circular cylinder?

Suppose that the radius of considered right circular cylinder be 'r' units.

And let its height be 'h' units.

Then, its volume is given as:

[tex]V = \pi r^2 h \: \rm unit^3[/tex]

The formula for the volume of a cylinder is:

The area of cross-section x the height.

Since the cross-section is a circle, we use the formula π x r²

Radius= 30 / 2 =15

Thus, Area of cross-section

π x 15² = 706.8583471 inches²

Now that we know the area of the cross-section,

706.8583471 x 36 = 25446.90049

= 25446.90 (2dp)

So. the volume is 25446.90

DE is a line segment with endpoints D(-5,1) and E(3, 3). What are the coordinates of D’ and E’, the image of DE under a dilation of magnitude 1.5 and a center of dilation at the point (-4,2)?

Answers

First step is to calculate distance between point D and center of dilation:
x= |-4-(-5)| =1
y= |2-1| =1

Now we multiply this distance by the dilation factor
x_distance = 1 * 1.5 = 1.5
y_distance = 1 * 1.5 = 1.5

Now we do same for point E:
x= |-4-3| =7
y= |2-3| =1

Now we multiply this distance by the dilation factor
x_distance = 7 * 1.5 = 10.5
y_distance = 1 * 1.5 = 1.5

Now we need to find coordinates for points D' and E'.
Point D':
x = -4 - 1.5 = -5.5
y = 2 + 1.5 = 3.5
Point E':
x= -4 + 10.5 = 6.5
y= 2 + 1.5 = 3.5

amy has 30 grams of flour. she puts 4 grams of flour in each pot of chowder that she make. she puts 5 grams of flour in each pot of potato soup that she makes. she makes 4 pots of chowder. does amy have enough flour left over to makes 3 pots of potato soup.

Answers

No because if she has 30 grams of flower, 16 are being used by the chowder. She would only have 14 grams of flour left and she would need 15 for 3 pots of potato.

After using 16 grams of flour to make 4 pots of chowder, Amy has only 14 grams of flour left, which is not enough to make 3 pots of potato soup, each requiring 5 grams of flour.

To solve this problem, we need to calculate the total amount of flour Amy uses for the chowder. Since she makes 4 pots of chowder, she would need:

4 pots × 4 grams/pot = 16 grams of flour

After making the chowder, Amy would have 30 grams - 16 grams = 14 grams of flour left.

Amy wants to make 3 pots of potato soup, and each pot requires 5 grams of flour. Therefore, she would need:

3 pots × 5 grams/pot = 15 grams of flour for the potato soup

Since Amy has only 14 grams of flour remaining, she does not have enough flour to make 3 pots of potato soup.

On average, 75% of the days in Henderson county are sunny, with little or no cloud cover. Describe a model that you could use to find experimental probability of sunny days each day for a week in Henderson county.

Answers

We have that the probability to have a sunny day is approximately 75%. Hence, the probability that we have 2 sunny days in a row is 75%* 75% (we are kind of assuming that the weather of a day plays no role on the weather of the next day, which is not completely true). That is because for it to 2 sunny days, both days have to be sunny. It is analogous to a coinflip; the chance we get 2 heads is 50%*50%, the chance we get 3 heads is 50%*50%*50% and so on. Hence, we have that the chance that a week is sunny in the county is 75% to the seventh power. This yields that the chance is around 13.3%

One possible model is:

You could place 3 red marble and 1 blue marble in a bag. The probability of drawing a red marble would be 3/4, which is 75%; this means red marbles would be sunny days and blue marbles would be cloudy days.

Each draw out of the bag would represent one day of the week. Draw a marble 7 times, replacing it after each draw. This would represent the weather for the days of the week.

Answers

The possible length of side XZ could be 50 mm

Which could be the length of side XZ?

From the question, we have the following parameters that can be used in our computation:

The length of side XY = 29 mmThe length of side YZ = 43 mm

Using the triangle inequality theorem, we have

Smallest length of XZ = 43 - 29

Smallest length of XZ = 14

Largest length of XZ = 43 + 29

Largest length of XZ = 72

So, we have

Range: 14 < x < 17

This means that the length of side XZ could be 50 mm because 50 is in the range 14 < x < 17
