Answer:
-3/4
Step-by-step explanation:
An irreducible fraction (or fraction in lowest terms, simplest form or reduced fraction) is a fraction in which the numerator and denominator are integers that have no other common divisors than 1 (and −1, when negative numbers are considered).
so
-30/40 =
-3/4
a light flashes every 8 seconds how many times will it flash in 3 minutes
The product of a number decreased by 3 and the same number increased by 8 is 80.
Answer:
-13, 8
Step-by-step explanation:
(x-3)(x+8) = 80
use FOIL to eliminate parenthesis
x² +8x - 3x - 24 = 80
combine like terms
x² + 5x - 24 = 80
move the constant to the left
x² + 5x - 104 = 0
factor x and then factor -8
x(x+13) - 8(x+13) = 0 factor (x+13)
(x+13)(x-8) = 0
separate into possible cases
x + 13 = 0
x - 8 = 0
solve
x = -13
x = 8

What is the answer to this word problem:
The sum of two numbers is 207. The difference between the two numbers is 11.
Find the greater number?
Answer:
109
Step-by-step explanation:
let the greatest number=x
therefore, the other number=x-11
Since, x+x-11=207
==> 2x-11=207
==> 2x=218
==> x=109
Solve for x
Angles around a point
Answer:
205°
Step-by-step explanation:
The total circle is 360°. The right angle is 90°, and you know the other angle is 64°. 90° + 64° is 154°. 360° -154° is 205°.
Answer:
We know that the angle around any given point is 360°
Therefore, according to the given problem,
[tex]x° + 64° + 90° = 360° \\ x° + 154° = 360° \\ x° = 360° - 154° \\ \boxed{x° = 206°}[/tex]
Hence, the value of x° is 206°
x° = 206° is the right answer.Can someone plz help me

Jeremy needs 1/2 cup of milk for 2/3 cup of oats how many cups of milk is needed for each cup of oats
Using the principle of proportional relationship, the number of milk cups required per cup of oat is 0.75 cups
Setting up a proportional relationship between milk and oat :
1/2 cups = 2/3 cups
x cups = 1 cup
Cross multiply :
(2/3)x = 1/2
0.666666x = 0.5
Divide both sides by 0.66666 to isolate x
x = 0.5 / 0.666666
x = 0.75
Therefore, 0.75 cups of milk is required per cup of oat.

Claire bought just enough fencing to enclose either a rectangular garden or a triangular garden, as shown. The two gardens have the same perimeter. How many feet of fencing did she buy?
Answer:
124Step-by-step explanation:
Given,
Perimeter of fencing bought by Claire for rectangular garden
= 2(4x - 4 + x - 4)
= 2 ( 5x - 8 )
= 10x - 16
Perimeter of fencing bought by Claire for triangular garden
= (3x - 1) + (3x - 1) + 3x
= 3x + 3x + 3x - 1 - 1
= 9x - 2
Since,
The two gardens have same perimeter,
By the problem,
10x - 16 = 9x - 2
=> 10x - 9x = 16 - 2
=> x = 14
Hence,
Feet of fencing bought by her,
Putting value in any of the perimeters of the gardens,
10x - 16
= 10(14) - 16
= 140 - 16
= 124 feet (Ans)
The Royals softball team played 75 games and won 55 of them what percent of the games did they lose? (part whole percent)
Answer:
27%
Step-by-step explanation:
75-55=20
75 - 100%
20 - x%
x=20*100:75=26.(6)7~27%
Answer:
They lost 29.3% of the softball games.
Step-by-step explanation:
Total number of games = 75
Number of games won = 55
Number of games lost = 75 − 55 = 22
Percentage of games lost: Number of games lost/ total games x 100%
Which means: 22/75 x 100% = 29.3%

Ms. Knight's two cooking classes are
making a total of 30 sweet potato
pies. Each pie requires 2 % sweet
potatoes. Her first class makes 1/3 of
the total number of pies needed.
Exactly how many sweet potatoes
will her second class need in order to
make the remaining pies?
Answer:
20
Step-by-step explanation:
In class 1, they used 10 sweet potatoes.
If they need 30, in class 2, they used 20.
The second class needs 0.4 sweet potatoes to make the remaining pies.
What is the percentage?The percentage is defined as a ratio expressed as a fraction of 100.
If Ms. Knight's two cooking classes are making a total of 30 sweet potato pies and each pie requires 2% sweet potatoes, then the total amount of sweet potatoes needed is:
30 pies x 2% sweet potatoes per pie = 0.6 sweet potatoes
Her first class makes 1/3 of the total number of pies needed, which is:
1/3 x 30 pies = 10 pies
This means that the first class used:
10 pies x 2% sweet potatoes per pie = 0.2 sweet potatoes
So, the second class needs to make the remaining pies, which is:
30 pies - 10 pies = 20 pies
The second class needs to use:
20 pies x 2% sweet potatoes per pie = 0.4 sweet potatoes.
Therefore, the second class needs 0.4 sweet potatoes to make the remaining pies.

Compute the value of S
Step-by-step explanation:
sum of all angles of triangle are 180°
therefore,
angle,
P + T + S = 180°
P = 90° , T = 36° ( given )
so,
→ 90 + 36 + S = 180
→ 126 + S = 180
→ S = 180 - 126 = 54°
→ S = 54°
therefore, S is 54° so, option D is correct.
