of the 50 students in the cafitera, 7 have red hair. If there are 750 students in the school, predict the number of students who have red hair.

Answers

So first, start with a ratio.
7:50
7 being those with red hair, to the 50 students.
There are 750 students total, so to get there multiply each side of the ratio by 15.
105:750

Therefore, a prediction you could make is that 105 students have red hair.

NEED HELP ASAP!! which function has a range of y is greater than or equal to 0

Answers

Answer:

c

Step-by-step explanation:

The third function has a range of y that is greater than or equal to 0.

What is a function?

A function is a kind of rule that, for one input, gives you one output.

For the first function, it contains negative values for y, so it was eliminated.

The second function did not start from zero, so it was eliminated.

The third function obeys the given condition, but the last function contains negative values for y.

Hence, the third function satisfies the condition that y is greater than or equal to 0.

Two angles of a triangle measure 53. What is the measure of an exterior angle at each vertex of the triangle?

Answers

Answer:

53+53=106

180-106=74

74 + 53= 127 (answer 1)

53+53=106 (answer 2)

74+53=127 9answer 3)

The measure of each exterior angle is 106, 127, and 127 degrees if the two angles of a triangle measure 53.

What is the triangle?

In terms of geometry, the triangle is a three-sided polygon with three edges and three vertices. The triangle's interior angles add up to 180°.

We have:

Two angles of a triangle measure 53:

The measure of the angles of a triangle:

53, 53, (180-53-53)

53, 53, 74 in degrees

As we know,

The sum of the two interior angles of a triangle is equal to the exterior angle:

Exterior angle(1st vertex) = 53 + 53 = 106 degrees

Exterior angle(2nd vertex) = 53 + 74 = 127 degrees

Exterior angle(3rd vertex) = 74 + 53 = 127 degrees

Thus, the measure of each exterior angle is 106, 127, and 127 degrees if the two angles of a triangle measure 53.

Vhat is the equation of the line that is parallel to the
given line and passes through the point (2, 3)?
O x + 2y = 4
O x + 2y = 8
O 2x + y = 4
O 2x + y = 8

Answers

Step-by-step explanation:

second one because

only x+2y=8 passes through the point (2,3)

the proof is 2+2*3=2+6=8

if we replace the given point to the other equations we will take wrong results for example

first equation

x+2y=4. 2+2*3=2+6=8 that is not equal to 4

Slopes of lines which are parallel to each other is same. The equation of the line which is parallel to y = mx + c and passes through (2,3) point is y = m(x-2) + 3

How are parallel straight lines related?

Parallel lines have same slope, since slope is like measure of steepness and since parallel lines are of same steepness, thus, are of same slope.

In the line of the form [tex]y = mx + c[/tex], the coefficient of x, which is 'm' here, is the slope of the line [tex]y = mx + c[/tex]

Suppose that the given line be:

[tex]y = mx + c[/tex]

(we assume this, because the question is a bit incomplete as the initial line isn't given)

And we've to find the equation of a line which is parallel to the line given above, and passes through (2,3).

Suppose it be:

[tex]y = mx + b[/tex] (as the slope of parallel lines would be same).

This line passes through (2,3), so the equation must be true for (x,y) = (2,3).

Putting it, we get:

[tex]y = mx + b\\3 = m(2) + b\\3 - 2m = b[/tex]

Thus, the equation of this line is:

[tex]y = mx + b \\y = mx + (3-2m)\\y = m(x-2) + 3[/tex]

At the market, 8 batteries cost $10,
How much do 6 batteries cost?

Answers

Answer:

$7.50

Step-by-step explanation:

You can use proportions to find that 8/10 = 6/x

then you can multiply 10 by 6 and divide the result by 8 to get the answer.

You can also divide 10 by 8 to get 1.25 and multiply it by 6, as 10 divided by 8 gives you the unit rate, or the price of each battery. Then you multiply it by 6 to get 7.5, or the cost of 6 batteries.

QUADRATIC EQUATION – WORD PROBLEMS
Fatima got 16 marks more than Zahra in Math test. The product of their mark is 1380. Find their marks.

The answer 30 ,46
I just need the steps

Answers

Answer:

Fatima's points = 46

Zahra's points = 30

Step-by-step explanation:

Let's give names to the unknowns (the number of points each one got)

Fatima's points = y

Zahra's points = x

Now create the equations given by the info they provide:

"Fatima got 16 marks more than Zahra"

y = x + 16

"The product of their mark is 1380."

x * y = 1380

Now use the first equation as substitution for "y" in the second equation:

x * (x + 16) = 1380

reduce the expression:

x^2 + 16 x = 1380

x^2 + 16 x - 1380= 0

Solve using quadratic formula:

[tex]x=\frac{-16+/- \sqrt{16^2+4(1380)} }{2} \\x=\frac{-16+/- \sqrt{5776} }{2} \\x=-8+/- 38\\x = 30\,\,\,or\,\,\,x=-46[/tex]

we pick 30 since the scores from a test must be larger than zero.

Now we use the first equation to solve for the other variable;

y = 30 + 16 = 46

then x = 30 and y = 46
