Answer:

There are 147 students in the school.

Step-by-step explanation:

3/7 of the students are in sixth grade, 63 students are in the sixth grade.

take 63 and divide it by the numerator, 3, you get 21.

You now multiply the fraction by 21 to get the full number of students in the school.

3 * 21 = 63, 7 * 21 = 147

So 63 sixth graders out of 147 total students in the school.

Answer:

-23

Step-by-step explanation:

We are given the functions;

h(x) = 5x - 3 and j(x) = -2x

Now, we want to find h[j(2)]

j(2) = -2(2)

j(2) = -4

Thus;

h(-4) = 5(-4) - 3

h(-4) = -20 - 3

h(-4) = - 23

Answer:

45/7 rounds

6 3/7 rounds

Step-by-step explanation:

Here is the full question

Nicole is playing a video game where each round lasts 7/12 ​ fraction of an hour. She has scheduled 3 3/4 fraction hours to play the game. How many rounds can Nicole play? rounds

Number of rounds she can play = total time she has scheduled / length of each round

length of each round = 7/12

total time she has scheduled = 3 3/4

3 3/4  ÷ 7/12

3 3/4 x 12/7

convert to the total time scheduled to an improper fraction

to convert to improper fraction, take the following steps :

[tex]\frac{15}{4}[/tex] × [tex]\frac{12}{7}[/tex] = [tex]\frac{45}{7}[/tex] rounds or [tex]6\frac{3}{7}[/tex] rounds

Answer:

Equation B and Equation C

Step-by-step explanation:

We can pinpoint a solution of an equation on a graph by looking at where the two lines intersect. The points (2,12) quite literally mean when x is 2, y is 12. If two equations intersect at that very point, that is their solution.

Answer:

Answer is in attachment. I am really sorry if I'm wrong.

Step-by-step explanation:

Greatest common factor (GCF) is the highest number that is a factor of 2 numbers. Not sure if that makes sense.

For example, GCF of 8 and 4 is 4, because 4 is the highest factor that fits into both numbers. 4x2=8 and 4x1=4.

In this case, the height is 7, because that's the GCF of 21 and 70. There's no bigger common factor than that. 7x3=21 and 7x10=70

Now that we know the "height", even though there's no such thing as height when calculating the area, we know the length.

The area of something is length x width. Your assignment calls it height for some reason so we'll use height x length.

Area of the 2 shapes is already given, which is 21n for the first shape. Length of the first shape is 3n because 3nx7=21n. Recall that 7 is what we found earlier.

As we can see, the "height" of the 2nd shape is the same as the first, therefore it should also be 7.

Since we are given the area of the 2nd shape, we now know its length. Length of 2nd shape is 10, because 7x10=70.

Answer:

-.7x^9

Step-by-step explanation:

The solution of the expression 49x¹⁸ will be 7x⁹.

Expression in maths is defined as the relation of numbers variables and functions by using mathematical signs like addition, subtraction, multiplication, and division.

The radical sign, which may be read as either the nth root of x or x radical n, expresses the root of a number. The vinculum, or horizontal line that encircles the number, and the radicand, or number beneath it, are both technical terms.

The given expression is 49x¹⁸. The value of the expression will be solved as:-

E = √( 49x¹⁸)

E = √ (7² x x¹⁸ )

E = 7x⁹

Therefore, the square root will be equal to 7x⁹.

Answer:

Hence the distance is 3.16

Step-by-step explanation:

Given data

The bus stop is at the coordinates (5,4) and

x1=5

y1=4

The pond is at the coordinates (8,5)

x2=8

y2=5

The expression for the distance between two coordinates is

d=√((x_2-x_1)²+(y_2-y_1)²)

Substitute

d=√((8-5)²+(5-4)²)

d=√((3)²+(1)²)

d=√9+1

d=√10

d=3.16

Answer:

189.

Step-by-step explanation:

I divided 42 by 2 and got 21..

Then, I multiplied 21 by 9 and got 189!

Answer:

d) [tex](9*3/4)+y[/tex]

Step-by-step explanation:

b) [tex]9+y*(3/4)[/tex]

This expression is not equivalent, as the original expression, [tex]y+9*\frac{3}{4}[/tex] , has 9 multiplied to [tex]\frac{3}{4}[/tex] instead of y. You can interchange values like this when it comes to addition, but not multiplication.

c) [tex](y+9)(3/4)[/tex]

This expression is also not equivalent. After opening up the parentheses, it would again result in y being multiplied to [tex]\frac{3}{4}[/tex].

[tex](y+9)(3/4)\\= y(3/4)+9(3/4)[/tex]

d) [tex](9*3/4)+y[/tex]

This expression is equivalent, as 9 and [tex]\frac{3}{4}[/tex] are still being multiplied together and y is added to the product. We can actually rearrange this to look like the original expression:

[tex](9*3/4)+y\\=y+(9*3/4)\\=y+(9*\frac{3}{4} )\\=y+9*\frac{3}{4}[/tex]

Answer:

B: 6 units

Step-by-step explanation:

just took the test

The area of triangle GHJ is 6 square units.

A triangle is a 2-D figure with three sides and three angles.

The sum of the angles is 180 degrees.

We can have an obtuse triangle, an acute triangle, or a right triangle.

We have,

To find the area of triangle GHJ, we can use the formula:

Area = (1/2) x base x height

where the base is any one of the sides of the triangle, and the height is the perpendicular distance from that side to the opposite vertex.

We can choose any side of the triangle as the base, but it is convenient to choose the side that is horizontal or vertical to simplify the calculations.

In this case,

We can choose the base to be the side GH, which has a length of 3 units (since the x-coordinates of G and H are different).

To find the height of the triangle,

We need to draw a perpendicular line from the vertex J to the base GH, and then calculate its length.

Since the x-coordinate of J is 4 and the x-coordinates of G and H are both 1, the base GH is 3 units long.

Also,

The y-coordinate of J is 5, and the y-coordinates of G and H are both 1, so the height of the triangle is 4 units.

The area of triangle GHJ is:

Area = (1/2) x base x height

Area = (1/2) x 3 x 4

Area = 6 square units

Thus,

The area of triangle GHJ is 6 square units.
