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:

n = - [tex]\frac{37}{24}[/tex]

Step-by-step explanation:

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.

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:

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!

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:

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.

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.

Answer:

Step-by-step explanation:

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

SUM

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.
