The length of the base on an
isosceles triangle is 5x. The length of
a leg is 6x + 8. The perimeter of the
triangle is 107. Find the length of the
base.

Answer:

-65

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

Answer:

4 or 16.

Step-by-step explanation:

An isosceles triangle is one with two sides being the same sides, and the base a different one. If two of the lengths are 4 and 16, the last one has to be either of those.

Answer:

A) 12 and 15

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!

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

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 )

- 37 = 24n ( divide both sides by 24 )

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

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.

Answer:

angles   100.6 and 79.4   = 180 degrees

Step-by-step explanation:

supplementary angles add to 180

angles   100.6 and 79.4   = 180 degrees

100.6 -21.20= 79.4

x+ x-21.2 = 180

2x = 158.8

x= 79.4

  79.4 + 21.2= 100.6

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:

percentage of increase = 49%

Step-by-step explanation:

Percentage change for any value is given by

percentage change = (new value - old value)/old value * 100 %

If there is increase in new value, percentage change can be called as percentage increase.

If there is decrease in new value, percentage change can be called as decrease increase.

Distance covered in first half of game = 50.5 yards

Distance covered in first full game = 75 yards

percentage of increase = (Distance covered in first full game - Distance covered in first half of game)/Distance covered in first half of game * 100 %

percentage of increase = (75 - 50.5)/50.5 * 100% = 24.5/50 * 100%

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.
