Answer:

13

Step-by-step explanation:

First, we need to find the area of the rectangle that the triangle RST is in, which would be 4*5=20. Second, we need to subtract the three triangles so the remaining area would be the area of the triangle that we need to solve for. The sum of the areas of the three triangles would be: 1/2*2*5 + 1/2*2*2 + 1/2*4*3 = 5 + 2 + 6 = 13.

Answer:

The correct answer is;

Using this information, each student can prepare an infinite number of parallelograms

Step-by-step explanation:

The given parameters of the parallelogram Emily asks the students to bring are;

The measure of one of the angles of the parallelogram = 50°

The length of of one side of the parallelogram = 10 cm

The shapes which the parallelogram must not be are; rhombus, rectangle, or square

Using the given information, therefore, the number of different parallelograms the students can prepare is given as follows;

The number of different lengths of the other side of the parallelogram = Infinity - 1 = Infinity

Therefore, the number of different parallelograms the students can prepare  is an infinite number of parallelograms

Answer:

about 15.6cm.

Step-by-step explanation:

I got my answer of 15.6cm because I did the Pythagorean theorem.

a^2+b^2=c^2

The values of "a" and "b" are the legs of the triangle, and the value of "c" is the hypotenuse. So, the equation with the values given is 9^2+b^2=18^2.

Simplified is 81+b^2=324. Next, you have to subtracted 81 on each side, so you have "b" by itself. b^2=243. Now, I know that b^2= 243. Next, find the square root of 243. The square root of 243 is 15.58845727. This value rounded to the nearest tenth is about 15.6.

In conclusion, the measure of the other leg is about 15.6cm.

Answer:

(1) commutative property of the addition.

(2) distributive property of the multiplication and associative property of the addition.

(3) addition property of the equality.

(4) multiplication property of the equality.

Step-by-step explanation:

First we start with:

4x + 1 + x + 3 = -11

Here we use the commutative property of the sum, which says that:

A + B = B + A

So we can reorder the terms in a sum, and we can rewrite our equation as:

4*x + x + 3 + 1 = -11

Here we also used the associative property of the sum, that says that:

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

wich means that we can perform the sum in any order we want, then we can add the 3 and the 1

4*x + x + 4 = -11

Now we use the distributive property of the multiplication, which says that:

(A + B)*C = A*C + B*C

Then we can rewrite our equation as:

(4 + 1)*x + 4 = -11

Now we solve the sum in the parentheses to get:

5*x + 4 = -11

Now we can use the addition property of the equality, we can add (-4) in both sides to get:

5*x + 4 - 4 = -11  - 4

5*x = -15

Now we can use the multiplication property of the equality, and multiply both sides by (1/5) to get:

5*x*(1/5) = -15*(1/5)

x = -5

Answer:

288

Step-by-step explanation:

We can use a proportion to solve this problem:

4 : 100 = 12 : x

x = (12 x 100)/4 = 300 (total computers)

300 - 12 = 288

Answer:

C. x:3 and x = 11

Answer:

m < 3

Step-by-step explanation:

Cookies to decorate = 60

Time < 180 minutes

The inequality

60m < 180

Where,

m = number of minutes

60m < 180

m < 180/60

m < 3

Less than 3 minutes decorating each cookie

Answer:

1/4

Step-by-step explanation:

Answer:

There is a 3/95 probability that a granola bar is chosen one choice after the other without replacement.

Step-by-step explanation:

The probability of choosing a granola bar without replacing the first bar is 4/20, or 1/5. 4 represents the number of granola bars, and 20 represents the total snacks. Then there are 19 snacks and 3 granola bars which represents the 3/19 chance of getting a granola bar the second time without replacing it.

To find the probability of both of those events happening, multiply them.

(1/5) * (3/19) = 3/95.

Answer:

33.89

Step-by-step explanation:

How to Calculate Rounding to the Nearest 100th?

If the digit after hundredth is greater than or equal to 5, add 1 to hundredth. Else remove the digit. Example

124.586

The third digit of right of decimal point is 6

The second digit after decimal point is 8 which is greater than 5

So add 1 to 8

Result = 124.59

Answer:

it's 33.89 hope it helps

Answer:

Amount of time would be greater than 95 minutes

Step-by-step explanation:

We are told that machine B can pack 11 boxes per minute.

Thus, this is 11x where x represents number of minutes.

We are told that the factory revives an order of over 1100 boxes and that it had already packed 55.

Thus,the inequality equation is;

11x + 55 > 1100

Solving this;

11x > 1100 - 55

11x > 1045

x > 1045/11

x > 95 minutes

Answer:

x<y-3/13

Step-by-step explanation:

Switch sides'

13x+3<y

Subtract 3 from both sides

13x+3-3<y-3

Simplify

13x<y-3

Divide both sides by 13

13x/13<y/13-3/13

Simplify

x<y-3/13

Answer: price was $150

Step-by-step explanation: original price was x. When discount is 30%

Price is (100-30)% = 70 % from the original. 70% = 0.70

So we have an equation 0.7x = 105. And x= 105/0.7= 150

(8*1000000)+(8*1000000)=16 000 000

Answer:

a. -3

Step-by-step explanation:

Two numbers are additive inverses if they add to give a sum of zero. 3 and -3 are additive inverses since 3 + (-3) = 0. So, -3 is the additive inverse of 3.

Answer:

21

Step-by-step explanation:

84% of 25 is 21

The maximum score is 100%, 100÷25= 4, meaning each question was 4 points or 4% of the total grade 84÷4=21 .

Answer:

21 questions were correctly answered

Step-by-step explanation:

If one scores an 84% on a quiz, that means that as an expression out of 100, a person has gotten 84 correct. To find how much the 84% equates to, one must convert the percent to a decimal. This means that one must divide the 84 by 100. After doing so, multiply the result by the number of questions on the quiz. The value attained will be the number of questions answered correctly.

Convert percent to decimal:

84% / 100 = 0.84

Multiply by the number of questions to find the amount answered correctly:

25 * 0.84 = 21
