[tex]\text{Suppose the width of the rectangle is }x\text{ cm}[/tex]
[tex]\text{then the perimeter can be expressed as}[/tex]
[tex]2(24+x)=72[/tex]
[tex]24+x=36[/tex]
[tex]x=12[/tex]
[tex]\text{Therefore the area of the rectangle is }24\cdot x=24\cdot 12=288\text{ cm}{}^2[/tex]
Answer: Solution,
length (l) = 24 cm
perimeter (p)= 74 cm
Area (A) = ?
we know,
P = 2(l + b )
74 = 2( 24 + b)
74 = 48 + 2b
2b = 74 - 48
2b = 26
b= [tex]\frac{26}{2}[/tex]
b = 13
now,
A = l*b
= 24 * 13
= 312 cm square
Therefore, the area of the rectangle is 312 cm square.

how to convert quinary into binary numbers?
If this means x in base 5 is equal to y in base 2
You just have to divide in base 5 by 2
Let's take an example.

find the measure of the angle that is 12° more than two times its supplement
Answer:
56 and 124
Step-by-step explanation:
Sum of two supplementary angle = 180
Let the first angle be x
Second angle = 2x + 12
2x + 12 + x = 180
3x + 12 = 180
3x = 180 - 12
3x = 168
x = 168/3
x = 56
2x + 12
2(56) + 12
112 + 12
124

A baseball team won 16 games and lost 11. At this rate, how many games will it win in a 162-game schedule?
==========================================================
Explanation:
The team won 16 games and lost 11 so far. At this point in the season, they played 16+11 = 27 games total. Their win rate is 16/27.
Set this equal to x/162 which is the win rate for winning x games out of 162 played over the entire season.
Solve for x.
x/162 = 16/27
27x = 162*16 ... cross multiplication
27x = 2592
x = 2592/27
x = 96
The team would win 96 games if it kept the same winning rate going.
Notice that 16/27 = 0.5926 = 59.26% and how 96/162 = 0.5926 = 59.26% as well (both are approximate). This helps confirm we have the correct answer.
-------------------------
Here's another slightly longer way to solve. If you prefer the first method above, then ignore this section.
w = number of games won over the entire 162 game season
162-w = number of games lost over the entire season
w/(162-w) = win to loss ratio
16/11 = win to loss ratio after winning 16 games and losing 11
Setting those last two expressions equal to each other and solving for w gets us...
w/(162-w) = 16/11
11w = 16(162-w)
11w = 2592-16w
11w+16w = 2592
27w = 2592 ... this hopefully looks a bit familiar from before
w = 2592/27
w = 96 games won

The ratio of a basketball player's completed free throws to attempted free throws is 4 to 7. If she completed 12 free throws, find how many free throws she attempted.
a. 3 free throws
b. 7 free throws
c. 21 free throws
d. 4 free throws
Answer:
well for Evey 4 completed throws she takes 7 throws
with this ratio we get that;
it's 4:7
there fore
for 12 completed free throws she would take 21 free throws
option c is the answer
hope it's helpful
Answer:
21
Step-by-step explanation:
FreeThrows: FT
Attempted Throws: AT
FT/AT=4/7
12/AT=4/7
84/4=AT
AT=21

(A) Two acute angles add to an obtuse angle
(B) Two adjacent angles make a line
(C)Two obtuse angles are supplementary
Decide if each statement is always, sometimes, or never true.
I said never for the first one I’m new to geometry and I’m a freshman I’m taking notes along the way so whatever information you have for me will help!❤️
Answer:
(A) Two acute angles add to an obtuse angle
It's sometimes because for example if you take two acute angles
one is 30 and other is 20
they add to 50 and not greater than 90 so it can be sometimes greater but not always
(B) Two adjacent angles make a line
Its also sometimes because a line means it should be 180 degrees so two adjacent angles can out always be equal to 180 that is a line
(C)Two obtuse angles are supplementary
It's Never true because obtuse angles start from 90 so if you take 91 also and other 91 too so if we add them up that will be 182 not 180
as we know 180 = supplementary angle that's why
is fraction a linear equation
Answer:
NO
Step-by-step explanation:
We need more than two operations to solve a linear equation . If an equation contains fractions, multiply both sides of the equation by the least common denominator (LCD) to clear fractions.
Help!! Will give Brainiest
Answer:
add all the rest of the angles, and then subtract the sum from 1080, and that's your ans mate
Answer:
147
Step-by-step explanation:
If you add up all the angles you have, you get 933. Since an octagon has 1080 degree angles the last angle must be added to 933 to make it equal to 1080. If you subtract 933 from 1080, you get the remaining angle 147.

by using the formula, we can find :
T7 = [7⁴ - 6(7)³ +23(7)² - 18(7) +24] / 24 =
(2401 - 2058 + 1127 - 126 +24) / 24 =
1368/ 24 = 57
T8 = [8⁴-6(8)³+23(8)²-18(8)+24]/24 =
(4096-3072+1472-144+24)/24 =
2376/ 24 = 99

Please help ASAP and explain the answer, thank you
Answer:
Step-by-step explanation:
1) x² - 8x + 5 = 0
2) No subtract 5 from both sides
x² - 8x + 5 - 5 = 0 - 5
x² - 8x = -5
3) Now find (8/2) = 4. Add 4² = 16 to both sides
x² - 8x + 16 = -5 + 16
x² - 8x + 16 = 11
4) (x - 4)² = 11
5) Take square root both sides
x - 4 = ±√11
x = 4 ±√11
