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
Which inequality describes the relationship between points A and B on the number line?
Answer:
B > A
Step-by-step explanation:
B and A are both in between 0 and 1 on a number line.
On a number line, the further right you go, the higher numerical values get, and the further left - vice versa.
Anyhow, B is further to the right, as well as closer to 1 than A is, so we can assume that B is the greater number.

what is the additive inverse of 3?
a. -3
b. a+(-a)=0
c. 0
d. -a
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.

The hypotenuse of a right triangle measures 18 cm and one of its legs measures 9 cm.
Find the measure of the other leg. If necessary, round to the nearest tenth.
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

Eric goes to town with £15. He spends £8.50 on a new scarf.
He meets his nan who gives him £20 and tells him to take £10 of it home for his sister
Eric then sees a jumper he likes which costs £18.
If Eric buys the jumper, will he still have £10 to give it to his sister?
Show how you worked out your answer.
Answer: No he would have 8.5$
Step-by-step explanation:
15 - 8.50 = 6.50$ + 20$ = 8.5 so no he would be 1.5$ short
If Eric buys the jumper, he will not have £10 left to give to his sister.
To determine if Eric will still have £10 to give to his sister after buying the jumper, we need to calculate his remaining balance.
Initial amount Eric has = £15
Cost of the scarf = £8.50
Amount received from his nan = £20
Cost of the jumper = £18
Amount to give to his sister = £10
First, let's calculate Eric's remaining balance after buying the scarf:
Remaining balance = Initial amount - Cost of the scarf
Remaining balance = £15 - £8.50
Remaining balance = £6.50
Next, let's calculate Eric's balance after receiving money from his nan:
Total balance = Remaining balance + Amount received from nan
Total balance = £6.50 + £20
Total balance = £26.50
Now, let's check if Eric can still afford to buy the jumper:
If Eric buys the jumper:
New balance = Total balance - Cost of the jumper
New balance = £26.50 - £18
New balance = £8.50
The new balance after buying the jumper is £8.50. As we can see, this amount is less than the £10 Eric needs to give to his sister.
Therefore, if Eric buys the jumper, he will not have £10 left to give to his sister.

javier bought a microwave for $105. the cost was 30% off the orginal price. what was the price of the microwave before the sale? Step by Step
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
A basket of snacks contains 8 packs of oreos, 2 bags of chips, 6 packs of gummies, and 4 granola bars. Bill randomly choses 2 snacks. What is the probability a granola bar is chosen one choice after the other without replacing the first bar? {PLZZZZ HELP}
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.

An electronics store sold 4% of the computers that were on sale.
If only 12 computers were sold, how many computers were not sold?
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

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.

4). Machine “B” can pack 11 boxes per minute. The factory receives an
order for more than 1100 boxes. Machine B has already packed 55 boxes.
Write and Solve an inequality to find the amount of time it will take machine
B to pack the additional boxes that are needed for the order.
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
