Josey has 15 quarters, 20 dimes and 10 pennies. Express as a ratio the number of quarters to total coins.
Answer:
15 : 45, 15/45, 15 to 45
Step-by-step explanation:
15 + 20 + 10 = 45 total coins.
Ratio being quarters (15) to total coins (45)
Answer:
The ratio is 15:45
Step-by-step explanation:
First, we want to know how many total quarters Josey has, which says he has 15. Then, we need to know how many total coins he has. So, 15 + 20 + 10 = 45. So, there are 45 total coins. So the ratio is 15:45. Hope this helps!

Write an equation in function notation for the relation
shown at the right.
F f(x)=-2x H f(x)=x-2
G f(x)=2x+2 J f(x)=-x+2
The correct function is H, f(x) = x-2
What is a function?A function is defined as a relation between a set of inputs having one output each, a function is a relationship between inputs where each input is related to exactly one output.
Given is a graph,
Slope is rise over run, so it’s 1 up and 1 to the right.
It means that the slope is 1.
We know that, the general form of the linear equation y = mx+b where slope is m.
Here, So m is 1.
So we have y=x+b.
To find b plug in the point (0,-2) x=0 and y=-2
Thus, we get, b=-2
Therefore, the linear equation is y=x-2
Hence, the correct function is H, f(x) = x-2

Answer:
n = - [tex]\frac{37}{24}[/tex]
Step-by-step explanation:
Given
- [tex]\frac{7}{8}[/tex] = [tex]\frac{2}{3}[/tex] + n
Multiply through by 24 ( the LCM of 8 and 3 ) to clear the fractions
- 21 = 16 + 24n ( subtract 16 from both sides )

(B) 2/7 of the medals are bronze
(C) 40% of the total medals are gold
(D) more than half of the medals are silver
Answer:
pls help me as well
Step-by-step explanation:
btw which school do u study in?
the only statement that is definitely true based on the given ratio is (B) 2/7 of the medals are bronze.
Based on the given ratio of gold to silver to bronze medals being 2:3:2, we can deduce the following:
(A) Italy got a total of 7 medals: This statement cannot be determined based solely on the given ratio. The total number of medals received by Italy is not explicitly provided.
(B) 2/7 of the medals are bronze: This statement is true. Since the ratio of bronze medals to the total medals is 2/(2+3+2) = 2/7, it means that 2/7 of the medals are bronze.
(C) 40% of the total medals are gold: This statement is false. The ratio given does not indicate that 40% of the medals are gold. Without knowing the total number of medals, we cannot determine the percentage.
(D) More than half of the medals are silver: This statement is false. The given ratio indicates that the number of silver medals is less than the combined number of gold and bronze medals, which means that less than half of the medals are silver.
In summary, the only statement that is definitely true based on the given ratio is (B) 2/7 of the medals are bronze.

Answer:
More money was made at the spring concert
Step-by-step explanation:
Here, we want to know if more or less money was made during the spring or fall concert
from the question, we are told that the amount made at spring concert is 9/8 of what is made at a fall concert
Since 9/8 is greater than 1, we can confidently say that the amount made at the spring concert is greater than what she made at the fall concert

Answer:
The slope for both is ½ because every unit to the right (x axis) is increasing by 1.
Rise is 1, run is 2
Answer:
slope = [tex]\frac{1}{2}[/tex]
Step-by-step explanation:
Calculate the slope m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (- 8, 1) and (x₂, y₂ ) = (8, 9) ← 2 points on the green line
m = [tex]\frac{9-1}{8+8}[/tex] = [tex]\frac{8}{16}[/tex] = [tex]\frac{1}{2}[/tex]
Repeat with (x₁, y₁ ) = 0, 6) and (x₂, y₂ ) = (2, 7) ← 2 points on the blue line
m = [tex]\frac{7-6}{2-0}[/tex] = [tex]\frac{1}{2}[/tex]
Since the slopes of both lines are equal, then the lines are parallel
What percent of 300 is 26?
(Equation)
Step-by-step explanation: I would advise writing out the equation
by simply reading the problem from left to right and solving it from there.
So for this problem we have "what percent."
Since "percent" means over 100 and "what"
means x, "what percent" would be x/100.
The word "of" means times, 300 is 300, "is" means equals, and 26 is 26.
So we have x/100 · 300 = 26.
We can rewrite this problem as 300x/100 = 26.
To get rid of the fraction, we multiply both sides
by 100 and we have 300x = 2600.
Dividing both sides by 300, you can use a calculator to
find that x = 8.66666 which rounded to 8.67.
So 8.67% of of 300 is 26.
What is the value of x in the equation 2.5(6x - 4) = 10 + 4(1.5 +0.5x)?

O 2
O 13
Answer:x=2
Step-by-step explanation:
The value of x in the equation 2.5(6x - 4) = 10 + 4(1.5 +0.5x) is 2.
The correct option is C.
What is Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
We have,
2.5(6x - 4) = 10 + 4(1.5 +0.5x)
Solving the equation for x we get
15x - 10 = 10 + 6 + 2x
15x - 2x = 16 + 10
13x = 26
Divide both side by 13 we get
13x/ 13 = 26 /13
x= 2
Thus, the value of x is 2.

A rectangle whose area is 336 square feet has a length that is 4 meters less than
the twice the width. Find the dimensions of the rectangle.
Answer:
L = 2(16.675) - 13.2 = 20.15 ft
W = 16.675 ft
Solution
width = x
length = 2x - 4m
m = 3.3 ft
Area = W × L = 336 ft^2
(2x - 4(3.3)) × x = 336 ft^2
solve for x
2x^2 - 13.2x = 336 ft^2
quadratic equation reveals 2 X's
x = -10.075, 16.675
a distance can't be a negative so...
x = 16.675 ft
L = 2(16.675) - 13.2 = 20.15 ft
W = 16.675 ft

One angle of a triangle measured 95
the other two angles are in a ratio of 5:12what are the measures of those two angles
Answer:
Both angles: one = 25 degrees, the other equals 60 degrees
Step-by-step explanation:
Do 95 + 5x + 12x = 180.
x = the angle.
95 + 17x = 180.
minus 95
17x = 85
divide by 17.
x= 5
then do 5(5) and 5(12) to get your two angles.
Answer:
25 and 60
Step-by-step explanation:
One angle of a triangle measured 95
the other two angles are in a ratio of 5:12, what are the measures of those two angles?
So 95 + 5x + 12x = 180
(Combine like terms)
95 + 17x = 180
(Subtract 95 from both sides)
17x = 85
(Divide 17 from both sides)
x = 5
Now plug 5 into 5 and 12
5x = 25
12x = 60
60 + 25 + 95 = 180 :)

An airline states that an airplane flight between two cities takes 2.5 hours. The airline also says that the actual flying time can change by up to 15% of that amount.
What are the shortest and longest times for the airplane flight? Round your answer to the nearest tenth of an hour.
Enter the correct answers in the boxes.
Answer:
The shortest time is 2.1 hours and the longest time is 2.9 hours
Step-by-step explanation:
First, find the amount of time if it increases by 15%:
2.5(1.15)
= 2.875
= 2.9
Next, find the amount of time if it decreases by 15%:
2.5(0.85)
= 2.125
= 2.1
So, the shortest time is 2.1 hours and the longest time is 2.9 hours
The shortest time for the airplane flight will be; 2.125 hours and the longest time will be; 2.9 hours.
What is the percentage?A percentage is a minimum number or ratio that is measured by a fraction of 100.
Given that the flight take the time is 2.5 hours But the time can fluctuate by 15 %
We need to first calculate 15 % of 2.5 hours.
For this, we will use percentage;
15 % of 2.5 hours
= 15 / 100 × 2.5 hours
= 0.15 × 2.5 hours
= 0.375 hours.
Now, the shortest time is;
= 2.5 h - 0.375 h
= 2.125 h
Then, the longest time will be;
= 2.5 h + 0.375 h
= 2.875 h
Therefore, the shortest time for the airplane flight will be; 2.125 hours and the longest time will be; 2.9 hours.
