Armando used algebra tiles to represent the product 3 x (2 x minus 1). An algebra tile configuration. 3 tiles are in the Factor 1 spot and are labeled + x. 3 tiles are in the Factor 2 spot: 2 are labeled + x and 1 is labeled negative. 15 tiles are in the Product spot: 2 are labeled + x squared, 4 are labeled + x, 1 is labeled negative x, and 4 are labeled negative. Which is true regarding Armando’s use of algebra tiles? He used the algebra tiles correctly. He did not represent the two original factors correctly. The signs on some of the products are incorrect. Some of the products do not show the correct powers of x.

Answer:

1/6 = 0.167 or 16%

Step-by-step explanation:

Okay, so to go from a fraction to a decimal, you really just have to put the dot in the right place:

1/6 = 0.167 (rounded)

So 1/6 is 0.167 as a decimal

So to find the percentage:

0.167 x 10 = 16.7

So 1/6 is 16.7%

hope this helps:)

Answer:

Decimal: 0.166666667

Percent: 16.6666667%

Step-by-step explanation:

First a decimal:

Divide 1 ÷ 6: 0.166666667

Now a percent, to convert decimals to percents multiply them by 100 and add the percent sign:

0.166666667 ⋅ 100 = 16.6666667%

Answer:

If one rolls a dice 120 times, he/she expect to get a 2, 20 time

Step-by-step explanation:

The probability of getting a 2 when the dice is rolled 1 time is [tex]\frac{1}{6}[/tex]

Given - The dice is rolled for 120 times

Probability of getting a 2  is

[tex]\frac{1}{6} *120\\= 20[/tex]

Thus, if one rolls a dice 120 times, he/she expect to get a 2, 20 time

Answer:

b = 6

Step-by-step explanation:

here's your solution

=> 7/21 = b/18

=> by cross multiplication

=> 21b = 7*18

=> b = 126/21

=> b = 6

hope it helps

Answer:

b = 6

Step-by-step explanation:

To find the answer, find the GCF of 7 and 21, which is 7, and divide it by 7/7 to get 1/3, now the equation is 1/3 = b/18. How many times does 3 multiply to get 18? 6, multiply the first side of the equation by 6/6 to get 6/18, now we have 6/18 = b/18, since they are the same, b = 6

The measure of angle L from the given triangle KLM is 57°.

Law of Sines In trigonometry, the law of sines, sine law, sine formula, or sine rule is an equation relating the lengths of the sides of any triangle to the sines of its angles.

The formula for sine rule is sinA/a=sinB/b=sinC/c. Where, A=angle A, a=length of side a, B=angle B, b=length of side b, C=angle C and c=length side c.

Given that, in ΔKLM, l = 570 cm, k = 490 cm and ∠K=46°.

By using sine rule in the triangle KLM, we get

sinL/l=sinK/k

sinL/570=sin46°/490

Here, sin46°=0.7193

sinL/570=0.7193/490

sinL/570=0.001467

sinL=0.8367

∠L=sin⁻¹(0.8367)

∠L=57°

Therefore, by using sine rule the measure of angle L is 57°.

1/4 ÷ 2

Step-by-step explanation:

Answer:

the first option 1/4 ÷ 2

hope it helped!!!

Answer:

the discounted price by 10% is P(x) = 0.9x. the price minus a $150 coupon is C(x) = x - 150. so, if you go to the store, the item is discounted by 10%, so you're really only getting out of your pocket 90% of that, or 0.9x, but!!

The sale price of a tablet computer is option (C) 0.90P is the correct answer.

Sale price is the price that a customer pays to purchase a product or a commodity. It is a price above the cost price and includes a percentage of profit also. The price after the original price has been reduced by a discount.

For the given situation,

The discount of a tablet computer = 10% = 0.10

The original price of the tablet = P

Sale price = original price - original price(discount)

⇒ [tex]P-P(0.10)[/tex]

⇒ [tex]P(1-0.10)[/tex]

⇒ [tex]P(0.90)[/tex]

Hence we can conclude that the sale price of a tablet computer is option (C) 0.90P is the correct answer.

Process of elimination

Step-by-step explanation:

If Olive wants to choose a friend while not playing favorites, while also not being random, she has to eliminate the ones she knows she will NOT take on the trip. She can choose this by selecting the one she knows that will be best on the trip with her, depending on the situation.

Or, if Olive only has one friend, then it wouldn't be surprising that she would take that one friend on the trip, since she has no one else to choose. This way, it is not playing favorites, nor is it random. Hope this helps you!

Answer:

The area of parallelogram ABCD is equal to the area of parallelogram EFGH.

Step-by-step explanation:

Given

Parallelogram ABCD

[tex]A = (4,2)[/tex]

[tex]B = (7,2)[/tex]

[tex]C =(4,6)[/tex]

[tex]D = (1,6)[/tex]

Parallelogram EFGH

[tex]E =(-2,2)[/tex]

[tex]F = (-5,2)[/tex]

[tex]G = (-6,6)[/tex]

[tex]H = (-3,6)[/tex]

Required

Compare the areas of both parallelograms

The area of a parallelogram is:

[tex]Area =Base * Height[/tex]

So: To do this, we plot ABCD and EFGH on a grid, then we measure the base and the height of both.

See attachment 1 for ABCD

In (1), we have:

[tex]Base = 3\ units[/tex]

[tex]Height = 4\ units[/tex]

So, the area is:

[tex]A_1 = 3 * 4[/tex]

[tex]A_1 = 12[/tex]

See attachment 2 for EFGH

In (2), we have:

[tex]Base = 3\ units[/tex]

[tex]Height = 4\ units[/tex]

So, the area is:

[tex]A_2 = 3 * 4[/tex]

[tex]A_2 = 12[/tex]

By comparison, they both have the same areas

Answer:

The answer is J.

Step-by-step explanation:

To find the slope of the line, pick two dots on that are EXACTLY on the grid.

I picked (0,3) and (2,2)

First, count how many units down the two points are from each other

I counted one.

Then, count how many units they are away from the side.

I got 2.

Slopes are rise over run or y over c so the slope is 1/2

The line is negative, too as it is going down so the slope is negative.

Therefore, the slope is -1/2 and only one option have a slope of -1/2 and it’s J

Also, to know which number is the slope look for the number before the x. In slope intercept form, that is the slope.
