how many times larger is a centigram than a milligram? 10times | 100 times| 1000 times| 0.1 time
A centigram is 100 times larger than a milligram. So, the option b) 100 times is correct for this question.
1 centigram = 100 milligrams. A centigram is a unit of mass in the metric system, equivalent to one hundredth of a gram. A milligram, on the other hand, is a unit of mass in the metric system, equivalent to one thousandth of a gram. Therefore, a centigram is 100 times larger than a milligram. The conversion between the two units can be easily calculated as 1 centigram is equal to 100 milligrams. The use of centigrams is limited in common applications, with milligrams being the preferred unit for expressing very small masses, while grams and kilograms are used for larger masses.

At a carnival game, you randomly throw two darts at the board and break two balloons. What is the probability that both of the balloons you break are purple? Write your answer in simplified fraction form
If randomly throw two darts at the board and break two balloons, then [tex]\frac{2}{35}[/tex] is the probability that both of the balloons you break are purple.
Considering what is meant by probability,
However, you must be aware that probability refers to the likelihood—greater or lesser—of a given event occurring.
In other words, probability creates a connection between the total number of conceivable events and the number of favorable events.
Then, the ratio between the number of favorable circumstances (cases in which event A may or may not occur) and the total number of possible cases is used to define the likelihood of any event A. Laplace's Law is what governs this.
[tex]P(A)=\frac{number of favorable cases}{number of possible cases}[/tex]
If the occurrence of one of them has an impact on the occurrence of the other, then two occurrences A and B are dependent. The likelihood for events that are dependent is:
P(A and B)= P(A)× P(B|A)
The phrase "the probability of B, provided that A has occurred" is denoted by the symbol P(B|A).
In this instance:
[tex]P(A)=\frac{4 balloons}{15 balloons} =\frac{4}{15}[/tex]
If the first balloon is purple, there are still 3 purple balloons available out of the total of 14. P(B|A) then equals [tex]\frac{3}{14}[/tex].
[tex]P(A and B)=\frac{4}{15} *\frac{3}{14}[/tex]

Thank You!:)
The solution to the equation 2n + 5 = 6( n² - 5 ) is n = ( 1 - √(211 )) / 6 and n = ( 1 + √(211 )) / 6
What is the solution to the quadratic equation?Given the quadratic equation in the question;
2n + 5 = 6( n² - 5 )
First we simplify the given equation;
2n + 5 = 6( n² - 5 )
2n + 5 = 6n² - 30
6n² - 2n - 5 - 30 = 0
6n² - 2n - 35 = 0
To solve for n, we use the quadratic formula.
n = (-b±√(b² - 4ac)) / (2a)
Compare 6n² - 2n - 35 = 0 to the quadratic equation in its standard form an² + bn + c = 0.
a = 6b = -2c = -35Plug the values into the quadratic formula
n = (-b±√(b² - 4ac)) / (2a)
n = ( -(-2) ±√( (-2)² - 4 × 6 × -35 )) / (2 × 6 ))
n = ( 2 ±√( 4 + 840 )) / ( 12 )
n = ( 2 ±√( 844 )) / ( 12 )
n = ( 2 ±2√(211 )) / ( 12 )
n = ( 1 ± √(211 )) / 6
n = ( 1 - √(211 )) / 6 or n = ( 1 + √(211 )) / 6
Therefore, the values of n are ( 1 - √(211 )) / 6 and ( 1 + √(211 )) / 6.

Emma is starting a cupcake business and borrows money from Dixons dynamite deals (DDD) .she agrees to pay back the loan after 10 years by making one payment of 80,000 , interest is compounded and fixed at 14,6% per annum.hpw much did emma borrow from (DDD) ?
The amount (present value) that Emma borrowed from Dixons Dynamite Deals (DDD) to repay after 10 years with a one-time payment of $80,000 at 14/6% compounded interest per annum is not more than $20,475.94.
Step-by-step explanation:
To find out how much Emma borrowed from Dixons Dynamite Deals (DDD), we can use the formula for the future value of a loan with compound interest:
Future Value (FV) = Principal Amount (P) * (1 + r)^n
Where:
P = Principal amount (the amount borrowed)
r = Interest rate per period (in decimal form)
n = Number of periods
In this case:
Future Value (FV) = $80,000 (the payment Emma will make after 10 years)
Interest rate (r) = 14.6% per annum = 0.146 (in decimal form)
Number of periods (n) = 10 years
Now, let's calculate the principal amount (P):
$80,000 = P * (1 + 0.146)^10
Now, let's solve for P:
P = $80,000 / (1.146)^10
P ≈ $80,000 / 2.97804
P ≈ $26,874.94
So, Emma borrowed approximately $26,874.94 from Dixons Dynamite Deals (DDD) to start her cupcake business.

For question 2,
How far are the Town Center and the Park
3.5 km and 650m
650m to km
1km = 1000m
To km = 0.65km
The distance = 3.5km - 0.65km
= 2.85km
So, they are 2.85km apart
For question 3,
A bottle = 1.75 liters of lemonade
A can = 330 ml of lemonade
1.75 liters to milliliters
1 liter = 1000 milliliter
= 1.75 × 1000 ml
= 1750 ml
2 bottles of lemonade
1750ml × 2
= 3500 ml
6 cans of lemonade
330ml × 6
= 1980 ml
In total, 3500ml + 1980ml
= 5480 ml

a necklace is made from purple pyramids and yellow spheres in a 1 : 6 ratio
By simplifying the ratio and adding the fractions, we found that 1/7 of the beads are purple pyramids.
Ratios are used to compare two quantities or values. They are often expressed in the form of a fraction or as a percentage.
The given ratio of purple pyramids to yellow spheres is 1:6. This means that for every 1 purple pyramid, there are 6 yellow spheres. We can express this ratio as a fraction:
Purple pyramids : Yellow spheres = 1 : 6
This can be simplified by dividing both sides by 6:
1/6 Purple pyramids : 1 Yellow sphere = 1/6 : 1
Now, we can add the two fractions to get the total fraction of pyramids in the necklace:
1/6 + 1 = 7/6
This means that out of every 7 beads, 1 is a purple pyramid. We can express this as a fraction:
1/7 of the beads are purple pyramids.
So, the fraction of the beads that are pyramids is 1/7.
