What do the sides measure if a rectangle if the area= 36” and the perimeter= 40”

Rashid [163]

36 = 6×6 or 4×9 or 2×18 or 1×36

6×6 does not work because 6 + 6 + 6 + 6 = 24

4×9 does not work because 4 + 4 + 9 + 9= 26

2×18 works because 2 + 2 + 18 + 18 = 40

No need to check other option

Therefore sides of rectangle is 2" and 18"

A 2 digit number is 5 times its units digit. the sum of the digits is 7. find the number

astraxan [27]

X - tens digit
y - units digit

$10x+y=5y\\
x+y=7\\\\
10x=4y\\
x=7-y\\\\
10(7-y)=4y\\
70-10y=4y\\
14y=70\\
y=5\\\\
x=7-5\\
x=2\\\\
10\cdot2+5=\boxed{25}$

Someone please help me!

HACTEHA [7]

Answer:

B and C describe vertical angles

Step-by-step explanation:

Point R will be the common vertex of any possible pair of vertical angles.

For a given line segment, such as AE, one end will designate a side of one of the vertical angles, and the other end will designate a side of the other angle of the pair.

For example, Choice B uses the crossing segments TN and FL and identifies the vertical angles TRF and NRL.

Choice C uses segments FL and AE to identify the vertical angles LRE and FRA.

__

Choice A does not involve crossing segments. Choice D makes use of segment AE, but the other points S and N are not on the same segment.

Answer: angle V = 41 degrees (choice B)

======================================================

Explanation:

We're told that RS = ST = RT. This means triangle RST has all three sides equal to one another. This triangle is equilateral. Each interior angle is 60 degrees. This is because each angle is y, and y+y+y = 180.

Since each angle of triangle RST is 60 degrees, this means angle STR is 60 degrees.

Let z be the measure of angle UTV. Note how

(angleSTR)+(angleUTV) = 180

60+z = 180

z = 180-60

z = 120

Making angle UTV to be 120 degrees

------------------------------------

Now we can focus on triangle UTV since we have expressions for each interior angle

U = 4x-9
T = 120
V = 5x+6

Add up those angles, set the sum equal to 180, solve for x

U+T+V = 180

(4x-9)+(120)+(5x+6) = 180

9x+117 = 180

9x = 180-117

9x = 63

x = 63/9

x = 7

Use that x value to find the missing angle measures

angle U = 4x-9 = 4*7-9 = 28-9 = 19 degrees

angle V = 5x+6 = 5*7+6 = 35+6 = 41 degrees

Note how

U+T+V = 19+120+41 = 180

which helps confirm our answer.
