in a class there are 48 students the number of the girls is 3 times how many boys and girls are in class​

Answers

Answer 1

Answer:

There are 12 boys and 36 girls.

Step-by-step explanation:

This equation should help explain it.

x + 3x = 48

Let's say that there are an x number of boys. Then there would be 3 times x of girls. So x (the boys) plus 3x (the girls) equal 48 (the total amount of students).

To solve this equation, first add x and 3x to get 4x. Then divide that by 48, and we get x = 2.

The amount of boys = x, so there are 12 boys.

The amount of girls = 3x, so there are 3 times 12, or 36 girls.

Kayla wants to create a right triangle with side lengths 16 millimeters, 30 millimeters, and 34 millimeters. Is this possible? Why or why not?
A- no, because 16+30 is not equal to 34
B- no, because 16 squared + 30 squared is not equal to 34 squared
C- yes, because 16 squared +30 squared is equal to 34 squared
D- yes, because 16+30 is greater than 34

Answers

Answer:

C

Step-by-step explanation:

16² = 256

30² = 900

256 + 900 = 1156

34² = 1156

Answer: C

Answer:

B: No, because 16 squared plus 30 squared is not equal to 34 squared

Step-by-step explanation:

So if she wants to make a right triangle that would look like this

           | \

           |     \

30mm |         \ 34mm

           |            \

           |_______\

              16mm

Which would make the Pythagorean theorem look like this

16^2 + 30^2 = 34^2

265 + 900 = 1156

1165 = 1156

So you answer would be B

What is the area of a semicircle with a diameter of 8 feet? Estimate using 3.14 for TT
A) 25.12 ft ²
B) 50.24 ft²
C)200.96 ft ²
D) 100.48 Ft²​

Answers

Answer: 25.12 ft²

Step-by-step explanation:

So  r = D ÷ 2

Since the area of a circle = πr²

then the area of a semi-circle =  (¹/₂π (¹/₂D)²)

Area of a semicircle given the diameter = (¹/₂π (¹/₂D)²)

                                                                  =  (¹/₂(3.14) (¹/₂ 8ft)²)

                                                                  = 25.12 ft²

How many solutions does the equation have? 3(7x + 4 ) - 2x + 8 = 5x + 12

Answers

Answer:

One solution

Step-by-step explanation:

Well, let's find out by solving the equation for x and seeing how many possible values there are. Our answer could be no solution, one solution, or infinite solutions. So, let's get started by writing out our equation:

3(7x + 4 ) - 2x + 8 = 5x + 12

First, we'll distribute the 3 onto the values on the left:

3(7x) + 3(4) - 2x + 8 = 5x + 12

21x + 12 - 2x + 8 = 5x + 12

Now, we can combine like terms. They are underlined and boldfaced below:

21x + 12 - 2x + 8 = 5x + 12

21x - 2x + 12 + 8 = 5x + 12

19x + 20 = 5x + 12

Next, let's take away 5x from both sides:

19x - 5x + 20 = 5x - 5x + 12

14x + 20 = 12

Finally, we'll subtract 20 from both sides:

14x + 20 - 20 = 12 - 20

14x = -8

Now, all we have to do is divide both sides by 14.

14x/4 = -8/14

x = -4/7

It looks like there is only one solution for x: -4/7. Hopefully that's helpful!

Four points are P(0,4), Q(0,3), R(2,0), S(0,5). Which three of them are collinear?​

Answers

Answer: P, Q and S

In other words, everything but point R.

============================================================

Explanation:

The term "collinear" means "points that fall on the same straight line". Any two points are always guaranteed to be collinear; however the same can't be said for any 3 random points.

In this case, points P, Q and S are all on the vertical y axis which is why they are collinear.

Answer:

Step-by-step explanation:

G. 10x3=3x10     1. Commutative property of multiplication

3. Associative property of Addition

F. (5x3)x4=5x(3x4)     4.Associative property of multiplication

J. If 11 = y then y = 11      5. Symmetric property

A. 21=21       6. Reflexive property

7. Transitive property

8. Zero property of multiplication

9. multiplicative inverse

D. 9x0=0    10. Zero property of multiplication

E. 4+0=4     11. Additive identity

H. 19x1=19   12. Multiplicative identity

B. If k=15 and 5 = 3m. Then k = 3m    This statement is not true.

This may be the transitive property, but this was written incorrectly. You have 15 in k = 15, but 5 in 5 = 3m.

C. 7+4=4+7      This is commutative property of addition, which is not listed above

I. 8x1/2=1     This statement is false. Maybe you meant 8 x 1/8 = 1. Then it is 9. Multiplicative inverse.

K. (6+2) + 1 = 6 + 2 + 1 This does not illustrate anything.

Maybe you missed the parentheses on the right side: 6 + (2 + 1). Then it is the associative property of addition.

L. 2+(2-)=0 If this were 2 + (-2) = 0, then it would be Additive Inverse, but I don't see this listed above.
