The perimeter of a rectangle is 42 cm and the area is 80 cm². Write an equation to model the situation and find the dimensions of the rectangle.
Answer:
16cm by 5cm
Step-by-step explanation:
P=2(l+w)
A= wl
80 factorization: 1, 2, 4, 5, 8, 10, 16, 20, 40, 80.
you then would have to find 2 numbers that would add up to make 42.
When you try 16*2+5*2= 32+10= 42 cm as your perimeter.
16*5= 80 cm^2 as your area.

An envelope has an area of 40 square inches and a perimeter of 28 inches. What are the dimensions of the envelope?
Answer:
10 inches by 4 inches
Step-by-step explanation:
Area of envelope, A = 40 in²
Perimeter of envelope, P = 28 in
Area = Length * width, L*W
Perimeter = 2(L + W)
40 = LW - - - (1)
28 = 2(L+W)
28/2 = L+W
14 = L+W - - - (2)
Solving like a quadratic equation ;
We need two numbers whose sum gives 14 and product gives 40
The numbers are 10 and 4
(10*4) = 40 and (10+4) = 14

The width of a rectangle measures (3s+t) centimeters,and it’s length measures (3s-9t) centimeters. Which expression represents the perimeter,in centimeters of the rectangle ?
Answer:
12s - 16t
Step-by-step explanation:
2(3s + t) + 2(3s - 9t)
6s + 2t + 6s - 18t
12s + 2t - 18t
12s - 16t
Answer:Perimeter of the rectangle =(12s -16t)centimeters.
Step-by-step explanation:
The perimeter of a rectangle is given as 2(l+w)
Given that width of the rectangle=(3s+t)centimeters. and
Length of the rectangle=(3s-9t)centimeters.
Solving we have
Perimeter= 2(l+w)
Perimeter=2(3s+t +3s-9t)
Perimeter=2(3s+3s -9t+t)
Perimeter=2(6s-8t)
Perimeter=(12s -16t)centimeters.

What is the measure of angle 7?
Answer:
82 degrees is the answer
Step-by-step explanation:
angle 6 and 7 are adjacent angles and adjacent angles add up to 180 deg. thus
angle 7 = 180 - 98 = 82 deg
The measure of ∠6 and ∠7 are on a straight line. This means there sum is equals to 180 degrees. Therefore, the measure of ∠7 is 82 degrees.
What is the sum of angle on a straight line?The sum of angle on a straight line is 180 degrees. This simply means the total angle on a straight line is 180 degrees.
∠6 = 98 degrees
Therefore,
∠6 + ∠7 = 180°(angles on a straight line)
∠6 = 98 degrees
Hence,
98 + ∠7 = 180
subtract 98 from both sides
98 - 98 + ∠7 = 180 - 98
∠7 = 82 degrees.

g(3) = 3^2 =9
g(-3) = (-3)^2 = 9
g(3) + g(-3) = 9+9 =18
Answer:

Step-by-step explanation:
g ( x) = x²
g ( 3 ) = ( 3 )² = 9
g ( -3 ) = ( - 3 )²
g ( - 3 ) = 9
g( 3 ) + g ( -3 ) = 9 + 9 = 18

Answer:
tanθ = [tex]\frac{15}{8}[/tex]
Step-by-step explanation:
let the unknown side be x , then
Using Pythagoras' identity in the right triangle
x² + 5² = 17²
x² + 25 = 289 ( subtract 25 from both sides )
x² = 225 ( take the square root of both sides )
x = [tex]\sqrt{225}[/tex] = 15
Then
tanθ = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{15}{8}[/tex]

WILL MARK BRAINLIEST FOR WHOEVER CAN ANSWER THESE :DDD
Answer:
P(black): 4/9
P(yellow): 2/9
P(orange): 3/9
Step-by-step explanation:
There are 4 black cubes, 2 yellow cubes, and 3 orange cubes. Add all of the cubes together to know how many cubes there are total.
4+2+3 = 9
Now that you know there are 9 cubes, you see how many black cubes you can draw out of 9. You can draw 4 black cubes out of the 9 total cubes, so the probability is 4/9.
You see how many yellow cubes you can draw out of 9. You can draw 2 yellow cubes out of the 9 total cubes, so the probability is 2/9.
You see how many orange cubes you can draw out of 9. You can draw 3 orange cubes out of the 9 total cubes, so the probability is 3/9.
Answer:
5) 4/9
6) 2/9

9. How much greater is 0.05723 than 0.005? ?
Answer:
0.05223
Step-by-step explanation:
0.05723 is 0.05223 greater than 0.005.
What is decimal?
A decimal number is one in which the whole number component and the fractional component are separated by a decimal point. The decimal point is the dot seen in decimal numbers. The decimal point is followed by digits that represent a number less than one.
As an illustration, consider the decimal value 17.48, where 17 is the entire integer and 48 is the decimal portion.
When is some number greater?When one number exceeds another, the phrase "more than" is used. Even greater than is utilised to compare the two weights.
How to solve it?
Take the difference
0.05723-0.005=0.05223
Hence, 0.05723 is 0.05223 greater than 0.005.
