may I have help please ?

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:

For this question we can use the pythagorean theorem: 20^2 + 4^2 = c^2

c^2 = 416

c =  [tex]\sqrt{416}[/tex]

Given:

The expression is

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

First steps of Iliana and Rod are given.

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."

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.

Answer:

   (-5, 3)

Step-by-step explanation:

B = 2M - A

B = 2(-2, 5) -(1, 7) = (-4-1, 10-7) = (-5, 3)

The constant of proportionality is the number with the letter x.

Answer:

y3+2y2+49y+98

Step-by-step explanation:

Answer:

Your correct answer is = (y + 2)(y^2 + 49)

Step-by-step explanation:

y3 + 2y^2 + 49y + 98

= (y + 2)(y^2 + 49)

Answer:

Step-by-step explanation:

This is just an addition question. If you have a calculator just add the numbers.

3.25 + 1.625 = 4.875 cups in the bowl.

Sometimes you can use another method. Sometimes it is shorter.

3 1/4 + 1 5/8 = 3 2/8 + 1 5/8 = 4 7/8.

7/8 = 0.875

Answer:

x-intercept=1/4     y-intercept= -1/8

Step-by-step explanation:

First, simplify the equation, y= 1/2x-1/8

Then you want to graph the equation with a slope of positive 1/2 starting at -1/8 that'll intercept across the x-axis at 1/4.

To find the y-intercept, you simply have to keep in mind that y=mx+b

b=y-intercept

So our y-intercept is stated in the equation after we simplified it

Answer:

19.22 US$

38.44 US$

Step-by-step explanation:

The interest Ryan's account earned for the first year is $9.61.

Simple interest is based on the principal amount of a loan or the first deposit in a savings account.

Mathematically,

SI = PRT/100

here, P is principle amount, R is the rate and T is the time.

Now it is given that,

Principle deposited by Ryan, P = $775

Interest, R = 1.24%

Time, T = 4 years

And for Brian,

Principle, P = $775

Interest, R = 1.24%

Time, T = 1 year

And Simple Interest for Ryan for 1st year,

SI = PRT/100

⇒ SI = (775*1.24*1)/100

⇒ SI = $9.61

Thus, The interest Ryan's account earned for the first year is $9.61.

Answer:

An inequality compares two values, showing if one is less than, greater than, or simply not equal to another value. a ≠ b says that a is not equal to b. a < b says that a is less than b. a > b says that a is greater than b. (those two are known as strict inequality)

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

Step-by-step explanation:

Which variable is represented by range in a linear function?

A. x-variable

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.

The true statements are;

Point D represents a number less than the number Point C represents

Point E represents the smallest number of all the numbers represented by points

Step-by-step explanation:

The given information are;

The number line with points are

[tex]-1\frac{3}{8} , -1\frac{1}{4} , -1\frac{1}{8} , -1..., \frac{3}{8}[/tex]

In decimal format, with Microsoft Excel and Word, we have;

-1.375, -1.25, -1.125, -1, -0.875, -0.75, -0.625, -0.5, -0.375, -0.25, -0.125, 0, 0.125, 0.25, 0.375

We have, E = -1.25, B = -1, D = -0.875, C = -0.25, A = 0, F = 0.25

The correct options are;

Point D = -0.875 < Point C = -0.25

Point E = -1.25 which is the second number on the number line and the smallest number of the numbers represented by points
