Gage's math teacher entered the seventh-grade student in a math competition. There was an enrollment fee of $30 and also $11 cha

Amanda [17]

Answer:

110 test

Step-by-step explanation:

Let

x ----> the number of packet of 10 test

y ----> the total cost

we know that

The number of packet of 10 test purchase multiplied by $11 plus the enrollment fee of $30 must be equal to $151

so

The linear equation that represent this scenario is

$y=11x+30$

we have

$y=\$151$

substitute

$151=11x+30$

Solve for x

subtract 30 both sides

$11x=151-30$

$11x=121$

Divide by 11 both sides

$x=11$

The number of packets purchase was 11

To find out the number of test, multiply the number of packets by 10

$11(10)=110\ test$

(2 thousands 7 tens) times 10

kodGreya [7K]

You can multiply the digits or the place value. Either way, you will get the same result.

(2 thousands, 7 tens) × 10 =

... (20 thousands, 70 tens)

or

... (2 ten-thousands, 7 hundreds)

Write a word problem about equal groups<br><br><br> and act it out to solve.

lina2011 [118]

Answer:

One scientist was working two molecules:

$BF_{3}, SO_{3}$

And verified that geometrically speaking, those are trigonal planar molecules made up of an equilateral triangle. He designed both molecules and classified them as Plane dihedral Groups. Was he correct? Why?

Step-by-step explanation:

Yes He was right. Place one atom in the centroid of the equilateral triangle (S or B), and each atom in each vertex(O or F).

We can apply geometric transformations (plane) rotations: R0, R2π/3, R4π/3

(And spatial ones, as R1, R2, R3 180º rotation over each median.)

Composite functions show that this is not an Abelian Group:

$R_{1}\circ\:R_{2}=R_{\frac{2\pi}{3}}\\R_{2}\circ\:R_{1}=R_{\frac{4\pi}{3}}\\$

What is the value of x? Round your answer to the nearest tenth if necessary.

katen-ka-za [31]

So to start off:

The equation you will want to use for the hypotenuse is

A (squared) + B (squared) = C (squared)

So you will want to fill in the equation like so:

7(7) + 4(4) = C (squared)

So now that you have your information filled out, put it all together!

49 + 16 = 65

Now don't forget that the 65 is SQUARED!

You will want to use the SQUARE ROOT method to help with that!

So what you will want to do is think of the numbers that are PERFECT SQUARES.

A perfect square consist of

Here is the list of perfect squares 1-10:

1 x 1 = 1

2 x 2 = 4

3 x 3 = 9

4 x 4 = 16

5 x 5 = 25

6 x 6 = 36

7 x 7 = 49

8 x 8 = 64

9 x 9 = 81

So look closely at these perfect squares, Do you see where 65 will lie?

It will lie between 8 and 9.

So you will do the square root now.

√65

The answer will come out as:

<span>8.06225775</span>

<span>You will then round it to the nearest tenths place (one after the decimal)</span>

You will look at the two numbers behind the decimal which is

0.6.

As you know,(If you round the tenths place), if the number in the hundredths is 5 or HIGHER. It will round up the number in the tenths place to 1.

So as we know 6 is higher than 5 so your answer would be:

8.1

I hope this helped! :)

HELP!!!!!!!!!!!!!!!!!!

padilas [110]

First, factor each expression by finding two terms whose product is equal to the c term and sum is equal to the b term.

x^2-x+6 --> (x-3)(x+2)

x^2-4 --> (x+2) (x-2)

Next, cancel the terms that are equal on the top and bottom.

You are left with the answer of: $\frac{x-3}{x-2}$

Hope this helps!!
