Answer:

5 students.

30 - 12 - 13 = 5.

Answer:

The answer is 5

Step-by-step explanation:

We need to find out how many students turned in the project on Wednesday. In order to do this, this is what we need to do.

1. First we need to subtract 12 from 30 since 12 is how many students turned in the project on Monday.

2. 30 - 12 = 18

So now we have 18.

3. Next we need to subtract 13 from 18 since we know that 13 is how many students turned in the project on Tuesday.

4. 18 - 13 = 5

At the end we end up with 5.

So 5 students turned in the project on Wednesday.

Answer:

x = 60.5

Step-by-step explanation:

ok this simple you already have the variable and the number on different sides

x2 = 121

divide each side by 2

x2 / 2 = x

121 / 2 = 60.5

x = 60.5

Answer:

60.5  

Step-by-step explanation:

    Divide 121 by 2, or just add 600.5 or multiply it by 2 and you get 121

Answer:

11,000 km/hr

Step-by-step explanation:

Distance= speed x time

time= 55 km/hr

speed= 200 kn

=200 km x 55 km/hr

= 11,000 km/hr

At an average speed of 55 km/hr the car will cover a distance of 200 km

in  3.6 hours.

A unitary method is a mathematical way of obtaining the value of a single unit and then deriving any no. of given units by multiplying it with the single unit.

We know, distance = speed×time or d = st.

Given, A car to travel 200 km if it has an average speed of 55 km/hr.

Therefore, From d = st we have,

200 = 55t.

t = 200/55.

t = 3.6 hours.

The relative speed is the net speed of two different objects with respect to each other.

If two objects move in the same direction we take the difference between their speeds.

If two objects move in the opposite direction we take the sum of their speeds.

Answer:

8.4

Step-by-step explanation:

Answer:

8.4 is the answer  :)

Step-by-step explanation:

Answer:

600

Step-by-step explanation:

Just below the solid line, there is the remainder and just above the solid line, there is a multiple of 12.

The number with a negative sign is being subtracted to the above number.

The first subtraction is mentioned as

5496-4800=696, observe that 696 is just below the solid line.

Now, proceeding further in the same way, the number below the second solid line is 96 which is obtained when the number in the box is being subtracted to the above number 696.

Let the number in the box is [tex]x[/tex]. So,

[tex]696-x=96[/tex]

[tex]\Rightarrow x=696-96=600[/tex]

Hence, the required number in the box is 600.

To find:

Which person wrote a correct possible first step.

Solution:

We have,

[tex](5.1\times 10^{-15})-(2.3\times 10^{-14})[/tex]

If we want -15 in the power of 10, then

[tex](5.1\times 10^{-15})-(2.3\times 10^{-14-1+1})[/tex]

[tex](5.1\times 10^{-15})-(2.3\times 10^{-15}\times 10)[/tex]

[tex](5.1\times 10^{-15})-(23\times 10^{-15})[/tex]

Therefore, first step of Rod  is incorrect.

If we want -15 in the power of 10, then

[tex](5.1\times 10^{-15+1-1})-(2.3\times 10^{-14})[/tex]

[tex](5.1\times 10^{-14}\times 10^{-1})-(2.3\times 10^{-14})[/tex]

[tex](\dfrac{5.1}{10}\times 10^{-14})-(2.3\times 10^{-14})[/tex]

[tex](0.51\times 10^{-14})-(2.3\times 10^{-14})[/tex]

Therefore, first step of Iliana is correct.

Answer:

B "Only Iliana is correct because Rod incorrectly equated 2.3 times 10 Superscript negative 14 and 0.23 times 10 Superscript negative 15."

Which variable is represented by range in a linear function?

Answer:

6.75

Step-by-step explanation:

27/4=6.75

Answer:

6.75 miles in 1/2 hour

Step-by-step explanation:

2 Hours =  4 x 1/2

27 : 4 = 6.75 miles per 1/2 hours

(-1,-2) would result in a relation that is no longer a function.

In the table, there's already x = -1 and y = -4. Function only gives a single y-value with x-value. If a single x-value gives two y-values then it'd not be Function.

If we add (-1,-2) in the table. The domain will be repetitive. Basically, we already have (-1,-4) and if we add (-1,-2) in the table, a single x-value will give TWO y-values which is not a function.

Answer:

a= 126

b= 54

c= 126

d= 54

e= 126

f= 54

g= 126

Step-by-step explanation:

To find a you would subtract 54 from 180 which would give you 126

Since a and b are another linear pair they would also add up to 180.

Then you move to c which is a linear pair with 54 so it is 126.

Because a and g are alternate interior angles they are congruent and they you continue with the same process for the first and check by seeing if the angles would be obtuse or acute to see if the angle measures would be correct.

The measure of the angles are a = 54, b = 54, c = 126, d = 54, e = 126, f = 54, and g = 126 degrees.

It is defined as the angles when two lines intersect each other and at the intersecting point, some pair of angles are formed which we call vertically opposite angles, as the name describes that they have vertically opposite angles.

It is given that:

The diagram shows two parallel lines cut by a transversal.

As we know from the definition of the vertically opposite angles:

b = 54 degrees

a + c = 54 + b  (a = c)

2a = 54x2

a = 54 degrees

Since a and g are opposite interior angles, they are congruent, so you proceed with the process as you did for the first and check to see if the angles are acute or obtuse to ensure that the angle measurements are accurate.

Similarly:

b = 54

c = 126

d = 54

e = 126

f = 54

g = 126

Thus, the measure of the angles are a = 54, b = 54, c = 126, d = 54, e = 126, f = 54, and g = 126 degrees.

Answer: 576 grams of sugar

Explanation: To solve this, you must do this following. First, you'd need to divide the 5 cans of MathJuice by their grams of sugar content. By doing this, you will find out how many grams of sugar are in each can. So, you'd divide 120 by 5 and get 24. This means that there are 24 grams of sugar in each can. Now, you'd need to multiple that by the number of cans in a case of MathJuice. You need to multiply 24 by 24. Doing this will get you a product of 576. Therefore, there are 576 grams of sugar in a case of MathJuice.

I hope this helped!

Answer:16

Step-by-step explanation:

the ratio is 6:13 meaning 6 is for men and 13 is for women so add 6 and 13 to get 19 . since the total number of people was 95 it will be represented by the total ratio 19 then to get the number of men it will be 6 times 95 then divide by 19 for women 13 times 95 then divide by 19 after that subtract men from women

Answer:

You can spend 4 days in Los Angeles and 3 days in San Francisco.

Step-by-step explanation:

From the information given, you can write the following equations:

x+y=7 (1)

275x+400y=2,300 (2), where:

x is the number of days to visit Los Angeles

y is the number of days to visit San Francisco

First, you can solve for x in (1):

x=7-y (3)

Now, you can replace (3) in (2):

275(7-y)+400y=2,300

1,925-275y+400y=2,300

125y=2,300-1,925

125y=375

y=375/125

y=3

Finally, you can replace the value of y in (3) to find x:

x=7-3

y=4

According to this, the answer is that you can spend 4 days in Los Angeles and 3 days in San Francisco.
