Greg and Marti are racing remote control cars. The race starts at t=0 and the cars distance is measured from the start line. Both cars have a constant rate of change. Information about each of the cars during the race is shown below.

Answer:

10%

Step-by-step explanation:

Using the data provided we are given the total number of people surveyed, which means we need to now find the total number of males that are not in favor of a five-day workweek. We do this by using the total of male participants and subtracting the number of male participants that are in favor of a five-day workweek

1800 (total) - 1200 (in favor) = 600

Now we know that 600 male participants are not in favor of a five-day workweek. Now we divide this number by the total amount of participants (both male and female) in order to find the percentage.

600 / 6000 = 0.1

0.1 * 100 = 10% ... multiply by 100 to get percentage.

Therefore only 10% of male participants are not in favor of a five-day workweek.

Answer:

5.85 kilograms

Step-by-step explanation:

We are told that Three hikers started climbing with each hiker carrying 7.8 kilograms of weight.

Thus, total weight carried by them = 7.8 × 3 = 23.4 kilograms

Now a fourth person joined them and they divided the weight equally.

Thus, each hiker will now carry;

23.4/4 = 5.85 kilograms

Answer:

Algebra 1 = 12 books

Algebra 2 = 5 books

Geometry = 6 books

Step-by-step explanation:

Given

Represent

Algebra 1 with A

Algebra 2 with B

Geometry with C

For the quantity

[tex]A + B + C = 23[/tex]

To represent the weight, we have that:

[tex]A = 4lb[/tex]

[tex]B = 5lb[/tex]

[tex]C = 3lb[/tex]

[tex]Total = 93lb[/tex]

This gives:

[tex]4A + 3B + 5C = 93[/tex]

The last sentence in the question can be represented with:

[tex]C + B = A - 1[/tex]

So, the expressions to work with are

[tex]A + B + C = 23[/tex] --- (1)

[tex]4A + 3B + 5C = 93[/tex] --- (2)

[tex]C + B = A - 1[/tex] --- (3)

Substitute A - 1 for B + C in (1)

[tex]A + B + C = 23[/tex]

[tex]A + A - 1 = 23[/tex]

[tex]2A - 1 = 23[/tex]

Solve for 2A

[tex]2A = 23 + 1[/tex]

[tex]2A = 24[/tex]

Solve for A

[tex]A = 12[/tex]

Substitute 12 for A in the (2) & (3)

[tex]4A + 3B + 5C = 93[/tex]

[tex]4 * 12 + 3B + 5C = 93[/tex]

[tex]48 + 3B + 5C = 93[/tex]

[tex]3B + 5C = 93 - 48[/tex]

[tex]3B + 5C = 45[/tex] ---- (4)

[tex]C + B = A - 1[/tex]

[tex]C + B = 12 - 1[/tex]

[tex]C + B = 11[/tex]

Make C the subject

[tex]C = 11 - B[/tex] ----- (5)

Substitute 11 - B for C in (4)

[tex]3B + 5C = 45[/tex]

[tex]3B + 5(11 - B) = 45[/tex]

[tex]3B + 55 - 5B = 45[/tex]

Collect Like Terms

[tex]3B - 5B = 45 - 55[/tex]

[tex]-2B = -10[/tex]

Solve for B

[tex]B = -10/-2[/tex]

[tex]B = 5[/tex]

Substitute 5 for B in (5)

[tex]C = 11 - B[/tex]

[tex]C = 11- 5[/tex]

[tex]C = 6[/tex]

Answer:

Step-by-step explanation:

The question is incomplete..

The given parameters can only solve for the number of hours the battery can last if at full capacity.

Given

25% = 4.5 hours

Required

Determine the brand

First, we need to determine the full capacity (100%)

So, we have:

25% = 4.5 hours

100% = x

Cross Multiply

25% * x = 100% * 4.5 hours

Divide both sides by 25%

x = 4 * 4.5 hours

x = 18 hours

Hence, the battery at full capacity is 18 hours.

So, to answer the question, you need to check the given list of brands.

The brand closest to 18 hours answers the question

Answer: -4

There are rules, just follow the rules

Answer:

Y = 9 + 2/3

Step-by-step explanation:

First, find the equation for the given points ((0, - 4) and (3, 2)). By graphing these points, I found that this equation was Y = -4 + 2/3.

Now, we can start to form the equation of the line you are trying to find. Because parallel lines must have the same slope, we know that the slope of the line will be 2/3. We can now use this slope to find the Y-intercept of the line. Add 2 to the X-coordinate and 3 to the Y-coordinate. By doing this you get the coordinates (0, 9). 9 is the slope of the second line.

Now we can make the equation you are trying to find. The answer is Y = 9 + 2/3 where 9 represents the Y-intercept and 2/3 represents the slope of the line.

Hope this helps! Let me know.

Answer:

the bottom one

Step-by-step explanation:

Answer:

2 solutions

Step-by-step explanation:

Given the 2 equations

y = x² + 4x + 4 → (1)

y = 2x + 7 → (2)

Substitute y = x² + 4x + 4 into (2)

x² + 4x + 4 = 2x + 7 ( subtract 2x + 7 from both sides )

x² + 2x - 3 = 0 ← in standard form

(x + 3)(x - 1) = 0 ← in factored form

Equate each factor to zero and solve for x

x + 3 = 0 ⇒ x = - 3

x - 1 = 0 ⇒ x = 1

Substitute these values into (2) for corresponding values of y

x = - 3 : y = 2(- 3) + 7 = - 6 + 7 = 1 ⇒ (- 3, 1 )

x = 1 : y = 2(1) + 7 = 2 + 7 = 9 ⇒ (1, 9 )

The 2 solutions are (- 3, 1 ) and (1, 9 )

Answer:

yes, Billy wrote the ratio correctly

Step-by-step explanation:

To indicate that you're using a ratio, you can use the division sign ( / ), a colon ( : ), or the word to. For example, if you wanted to say, "For every five men at the party, there are three women," then you could use any of the three symbols to state this. Here's how we go about it :

5 men / 3 women

5 men : 3 women

5 men to 3 women

Graph Inequality on Number Line

Graphing an inequality on a number line, is very similar to graphing a number. For instance, look at the top number line x = 3. We just put a little dot where the '3' is, right?

Now an inequality uses a greater than, less than symbol, and all that we have to do to graph an inequality is find the the number, '3' in this case and color in everything above or below it.

Answer:

x= 4 or -10

Step-by-step explanation:

Answer:

x = - 10, x = 4

Step-by-step explanation:

Given

2(x + 3)² = 98 ( divide both sides by 2 )

(x + 3)² = 49 ( take the square root of both sides )

x + 3 = ± [tex]\sqrt{49}[/tex] = ± 7 ( subtract 3 from both sides )

x = - 3 ± 7

Thus

x = - 3 - 7 = - 10

x = - 3 + 7 = 4

Answer:

35% because I took a test and got it right and a 100

Step-by-step explanation:

On the larger map, 1 inch represents an actual distance of 300 feet.

In the original map, 1 inch represents an actual distance of 300 feet.

Since the map is 12 inches square, the side length of the map is 12 inches. Therefore, the actual distance represented by the entire map is 12 inches * 300 feet/inch = 3600 feet.

In the larger version of the map, the side length is 50% longer than the original map. This means the side length of the larger map is 12 inches + (50% * 12 inches) = 12 inches + 6 inches = 18 inches.

To determine the actual distance represented by 1 inch on the larger map, we can set up a proportion:

12 inches (original map) corresponds to 3600 feet (actual distance)

1 inch (larger map) corresponds to x feet (actual distance)

Using cross-multiplication, we find that x = (1 inch * 3600 feet) / 12 inches = 300 feet.

1 inch on the larger map represents an actual distance of 300 feet.
