Answer:
46% of 127 is 58.42
Step-by-step explanation:
46/100 = x/127
Cross multiply
46 × 127 = 100 × x
5,842 = 100x
Divide both sides by 100
58.42 = x
Jasmine buys 3 T-Shirts and 3 Hats for $11.25. The next day, he buys 4 T-Shirts and 2 Hats for $10. How much does each T-Shirt and each Hat cost? Write a system of equations that can be used to solve the problem. Then solve the problem.
Answer: Each shirt costs $1.25, and each hat costs $2.5.
Step-by-step explanation:
Let x= Cost per T-shirt, y = Cost per Hat.
As per given,
3x+3y=11.25 (i)
4x+2y=10 (ii)
Multiply 4 to equation (i)
12x+12y=45 (iii)
12x+6y= 30 (iv)
Eliminate (iv) from (iii), we get
6y= 15
⇒ y = 2.5
Put value of y in (i)
3x+3(2.5)=11.25
⇒3x+7.5=11.25
⇒3x= 3.75
⇒x= 1.25
Hence, each shirt costs $1.25, and each hat costs $2.5.
what is 4 and 1/2 in decimal form
Answer:
4.50
Step-by-step explanation:
4 = Whole number. 1 = Numerator. 2 = Denominator. To get 4 1/2 in decimal form, we basically convert the mixed number to a fraction and then we divide the numerator of the fraction by the denominator of the fraction.
The decimal form of 4 and 1/2 is 4.5
DecimalDecimal is a fraction written in a unique form. The dot notation is used to represent the fraction form.
Therefore, 4 and 1/2 in decimal form is represented as follows;
Mixed fraction = 4 1 / 2
Improper fraction = 9 / 2

Jam is made from sugar and strawberries in the ratio of 3:5 A jar contains 150g of sugar how many grams of strawberries are in the jar
Answer:250
Step-by-step explanation:
150/3 =50
50x5=250
The quantity of strawberries in jar is 250 gram.
What is the ratio?Comparing two amounts of the same units and determining the ratio tells us how much of one quantity is in the other. Two categories can be used to categorise ratios. Part to whole ratio is one, and part to part ratio is the other. The part-to-part ratio shows the relationship between two separate entities or groupings.
Given the Jam is made from sugar and strawberries in a ratio of 3:5,
ratio of sugar to strawberries = 3/5
sugar in jam = 150 gram
let quantity of strawberries be x gram
the ratio of sugar to strawberries = 150/x
since both ratios are in proportions so
3/5 = 150/x
x = 150 * 5/3
x = 250 gram
Hence the quantity of strawberries is 250 grams.

Answer:
3 19/30 hours
Step-by-step explanation:
The given fractions will have 30 as a common denominator.
12/30 + 1 5/30 + 2 2/30 = (1 +2) +(12 +5 +2)/30 = 3 19/30 . . . hours
Jenny ran 3 19/30 hours this week.
Answer:
Step-by-step explanation:
Total hours that Jenny ran = 3.63 hours.
Step-by-step explanation:
Jenny ran on Tuesday for = 2/5 hours or 0.4 hours.
Time consumed to run on Thursday = 11/6 hours or 1.83 hours.
Time consumed to run on Saturday = 21/ 15 hours or 1.4 hours.
Here, the total hours can be calculated by just adding all the running hours. So the running hours of Tuesday, Thursday, and Saturday will be added to find the total hours.
Total hours that Jenny ran = 0.4 + 1.83 + 1.4 = 3.63 hours.

When a biased coin is thrown 4 times, the probability of getting 4 heads is
16
81
Work out the probability of getting 4 tails when the coin is thrown 4 times.
Answer:
1/81
Step-by-step explanation:
P(H,H,H,H)=16/81
fourth root of 16/81= 2/3
so the probability of getting tails would be 1/3
probability of getting 4 tails would be:
P(T,T,T,T)=(1/3)^4
=1/81
The probability of getting 4 tails when the coin is thrown 4 times is 1/81
How to determine the probability?We have:
P(Head 4 times) = 16/81
This means that:
P(Head)^4 = 16/81
Take the 4th root of both sides
P(head) = 2/3
The probability of a tail is calculated as:
P(tail) = 1 - P(Head)
This gives
P(tail) = 1 - 2/3
P(tail) = 1/3
When thrown 4 times, we have:
P(tail)^4 = (1/3)^4
P(tail) = 1/81
Hence, the probability of getting 4 tails when the coin is thrown 4 times is 1/81

Problem 3: The elevator at a business center has a weight limit of 1800 pounds. Assume the
average person weighs 160 pounds and has 3 pounds of items with them. What is the greatest
number of people that can ride the elevator at one time?
Answer
10
11
12
13
Weight limit of an elevator = 1800 pounds
Average weight of each person who comes in the elevator = 160 pounds
Quantity of items with them = 3 pounds
Let the number of people who can ride the elevator at one time be x.
Which means :
[tex] =\tt 160x + 3 = 1800[/tex]
[tex] = \tt160x = 1800 - 3[/tex]
[tex] = \tt160x = 1797[/tex]
[tex] =\tt x = \frac{1797}{160} [/tex]
[tex] =\tt x = 11[/tex]
Thus, number of people who can enter the elevator is 11.

Charles has 24 marbles. He has 6 more yellow marbles than blue marbles.
Which equation represents this situation?
Answer:
y = x + (6+x)
Step-by-step explanation:
Y represents the total number of marbles.
X represents number of blue marbles.
6+X represents number of yellow marbles.
To Solve:
24 = 2x + 6
Subtract 6 from both sides: 18 = 2x
Divide boths sides by 2: 9 = x
Now fill in the values: Blue Marbles = 9, Yellow marbles = 15

What is an equation of the line that passes through the points (4, -5) and (2, 0)?
Answer:
y = - [tex]\frac{5}{2}[/tex] x + 5
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (4, - 5) and (x₂, y₂ ) = (2, 0)
m = [tex]\frac{0+5}{2-4}[/tex] = [tex]\frac{5}{-2}[/tex] = - [tex]\frac{5}{2}[/tex] , then
y = - [tex]\frac{5}{2}[/tex] x + c ← is the partial equation
To find c substitute either of the 2 points into the partial equation
Using (2, 0 )
0 = - 5 + c ⇒ c = 0 + 5 = 5
y = - [tex]\frac{5}{2}[/tex] x + 5 ← equation of line

Angie is working on solving the exponential equation 23^x=6,; however she is not quite sure where to start. Using complete sentences, describe to Angie how to solve this equation.
And please don’t copy paste this and call it an answer
When you have problems like this you simply ask yourself what number do I have to multiply by 23 to get 6? This is how you might read this mathematical expression. So how do we solve the problem?
Well if x is the number that we have to multiply by 23 to get 6 that means that if we divide 6, 26 times we get x. So, x would be 6/23.
0.26
you would divide 23 on both sides
