Harriet works at the Mint, where new coins are made. Old and fake coins are also destroyed there. Harriet has 10 bags of $1 coins. All 10 bags contain the same number of coins. Harriet knows that nine bags contain only good coins and that one bag contains only fake coins. The fake coins are all about 0.5 gram short. Harriet has forgotten which bag contains the fake coins.
Harriet has a set of scales for weighing like the ones in the illustration. What is the lowest number of times she can weigh bags on the scales in order to find the bag of fake coins?
Answer:
3 times
Step-by-step explanation:
She would have to weigh the fake coins and another bag of real coins to spot a difference, and then she would need to check another bag to see which was correct. Maybe thats right.

What’s the answer for the question a,b,c,or d
Answer:
The answer is B.
Step-by-step explanation:
Right off the bat you can do process of elimination, and D is the least likely answer, and A isn't right either, and neither is C because 440/8 gives a remainder of zero either way. Which leaves us with B, which is the correct answer because the answer is 55.

1,200
1,500
3,120
5,200
Answer:
the answer is c)
Step-by-step explanation:
the reason is 5*6 would be 30 and if you were to add 3 more zero's, it would be 3000 and 1/10 of 600 is 60 so 60*2 is 120 which is where you het the 120 so you add it up and it's 3,120

After some bad news (due to a revolutionary but ultimately doomed process for making toast in a microwave oven), stock in Seraj Food Industries fell by 40%, to $324 a share. What was the original price of a share? Thank you so much i'll mark brainliest!
Answer:
Around $650
Step-by-step explanation:
The original price of a share is $540.
Given that, Seraj Food Industries fell by 40%, to $324 a share.
What is the percentage?A value or ratio that may be stated as a fraction of 100 is referred to as a percentage in mathematics. If we need to calculate a percentage of a number, we should divide it by its entirety and then multiply it by 100.
Let the original price of share be x.
x - 40% of x = 324
⇒ x - 40/100 × x = 324
⇒ x - 0.4x = 324
⇒ 0.6x = 324
⇒ x = 324/0.6
⇒ x = 540
Therefore, the original price of a share is $540.

To save money for prom this weekend, Tom is going to walk his neighbor's dog for $6 per hour and wash cars for $7.50 per hour. His mother sid he can work no more than 15 hours to ensure he keeps up with his homework. Tom needs to make at least $75 to cover prom expenses. If d represents the number of hours walking his neighbor's dog and c represents the number of hours washing cars, which system of inequalities represents this situation?
a
\large 6d+7.5c\le15
\large d+c\ge75
b
\large 6d+7.5c\le75
\large d+c\ge15
c
\large 6d+7.5c\ge75
\large d+c\le15
d
\large 6d+7.5c\ge15
\large d+c\le75
Answer:
d + c ≤ 15
6*d + 7.50*c≥ 75
Step-by-step explanation:
Mathematical inequality is that proposition that relates two algebraic expressions whose values are different. It is a proposition of relation between two different elements, either by greater, lesser, greater or equal inequality, or less or equal.
In other words, an inequality is obtained by writing two numerical or algebraic expressions related to any of the symbols>, <, ≥ or ≤.
You know Tom's mom said that he can't work more than 15 hours to make sure he keeps up with his homework. That is, the number of hours walking the neighbor's dog added to the car wash should not exceed 15 hours, that is, it must be less than or equal to that amount. If d represents the number of hours walking your neighbor's dog and c represents the number of hours washing cars, then it is possible to represent this by the following inequality:
d + c ≤ 15 Inequality (A)
On the other hand, you know that Tom needs to earn at least $ 75 to cover the expenses of this weekend's prom. In other words, the money earned by walking dogs added to that earned by washing cars must be equal to or greater than $ 75. If Tom will walk his neighbor's dog for $ 6 an hour and wash cars for $ 7.50 an hour, then $ 6*d is the money earned walking dogs and $ 7.50*c is the money earned from washing cars. So this is represented by the inequality:
6*d + 7.50*c≥ 75 Inequality (B)
Then the system of inequalities that represents this situation is given by the Inequation (A) and the Inequation (B)

Answer:
Negative × positive = negative
positive ÷ negative = negative
negative ÷ positive = negative
positive x negative = negative
Step-by-step explanation:
1. Negative × positive = negative
- × + = -
2. positive ÷ negative = negative
+ ÷ - = -
3. positive ÷ positive = positive
+ ÷ + = +
4. negative x negative = positive
- × - = +
5. negative ÷ positive = negative
- ÷ + = -
6. positive x positive = positive
+ × + = +
7. negative ÷ negative = positive
- ÷ - = +
8. positive x negative = negative
+ × - = -
Negative × positive = negative
positive ÷ negative = negative
negative ÷ positive = negative
positive x negative = negative
Note: when the signs are different, they will give negative
When the signs are the same, they will give positive

If angle P measures 50 degrees, what is the measure of angle Q?
A).50°
B).130°
C).40°
D).180°
Answer:
130 degrees
Step-by-step explanation:
Since angles P and Q are supplementary (meaning that they add up to 180), we can set up the equation:
180 = 50 + Q
Q = 130
Answer: B) 180°
Step-by-step explanation:
Angle P and Q forms a straight line which means they add up to 180 degrees.
So angle P is 50 degrees then we need to find it's supplement.
Using the equation 50 + x = 180 we can solve for x to find the supplement.
50 + x = 180 subtract 50 from both sides
-50 -50
x = 130

Given: < 1 and <3 are vertical angles
prove: <1 congruent to <3
Answer:
<1 ≅ <3 (congruence property)
Step-by-step explanation:
Given that: <1 and <3 are vertical angles.
Prove: <1 congruent to <3
Vertical angles are angles that are vertically opposite, and are formed under the same conditions. Thus, they are always congruent.
<1 + <2 = [tex]180^{o}[/tex] (sum of angles on a straight line)
Also,
<2 + <3 = [tex]180^{o}[/tex] (sum of angles on a straight line)
So that,
<1 + <2 ≅ <2 + <3 = [tex]180^{o}[/tex]
Thus, we can say that;
<1 + <2 ≅ <2 + <3
Since <2 is a common angle on both sides, then;
<1 ≅ <3 (congruence property)
