a rectangle has a length of 12 cm and a height of 5 cm. how long is the diagonal
Answer:
13cm
Step-by-step explanation:
The formula for diagonal is [ d = √h²+l² ] where h = height and l = length.
Solve with what we are given.
d = √5²+12²
d = √25+144
d = √169
d = 13

The school orchestra sells snacks at thier concerts to raise money. At the spring concert they made 9/8 as much money as they made at their fall concert. Did they make more money at their spring or fall concert?
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
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.

*XTRA PTS* can someone please explain how to find the domain and the range of a coordinate/set of relations
Answer:
Domain: X coordinates
Range: Y coordinates
Step-by-step explanation:
The domain is the set of all first elements of ordered pairs (x-coordinates). The range is the set of all second elements of ordered pairs (y-coordinates). Only the elements "used" by the relation or function constitute the range. Domain: all x-values that are to be used (independent values).The range is the set of all second elements of ordered pairs (y-coordinates).

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 :)

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!

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.

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:

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]

The ratio of the numbers of gold to silver to bronze is 2:3:2. What is definitely true about the medals Italy got

(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:
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

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.
