Find the area of each rectangle first
and then add the two areas together.
Answer:
44m²
Step-by-step explanation:
Area of larger rectangle
= length × breadth
= 8m × 4m
= 32m²
Area of smaller rectangle
= length × breadth
= 4m × 3m
= 12m²
Total area of the figure
= Area of larger rectangle + Area of smaller rectangle
= 32m² + 12m²
= 44m²

Pls Someone Help me Question:make the greatest and smallest 4 digit number by using any one digit twice
= 8,2,7
Answer:
Greatest digit: 8872.
Smallest digit:2278.
9514 1404 393
Answer:
greatest: 8872smallest: 2278Step-by-step explanation:
Greatest
The greatest possible number is created by putting the greatest allowable digit in the space available that has the highest possible place value. Here, the greatest digit is 8, and the highest place value of a 4-digit number is the thousands place: 8000. Once you have filled that place, you can use the digit 8 one more time in the hundreds place: 8800.
Now, the greatest digit available is the digit 7, and the left-most place you can put it is the tens place: 8870. Finally, the only digit and place available are the digit 2 and the ones place.
Your greatest 4-digit number is 8872.
Smallest
To form the smallest number, you use a similar process, filling places in the number from left to right with the smallest allowable digit. The smallest digit, 2, is allowed twice, so the smallest number that can be formed is 2278.

g(t) = 5t^2 − 8t + 3
Answer:

g(2)
g(2) = 5(2²) - 8(2) + 3 = 20 - 16 + 3 = 7g(t - 2)

If 5cm and 3cm are added to the length and width of a square, the perimeter of the resulting rectangle is between twice and three times the perimeter of the original square. Find the possible lengths of the sides of the original square.
Answer:
The answer is between 2 and 4. 2 and 4 can be included if you are including the twice or three times. If it doesn't include those then it would only be anything inbetween.
Step-by-step explanation:
So to start off I would always give placeholder for all the sides. Lets label it x.
2(x+5) + 2(x+3) < 3(4x)
In the equation above, we created a simple equation with 2 representing 2 sides each and the 3 and 5 plugged in. That all is going to be less than 3 times the original perimeter which is 4x for the 4 sides.
2x + 10 + 2x + 6 < 12x
4x + 16 < 12x
16 < 8x
2 < x
We learn that the original x is greater than 2. We don't say it is equal to since it says between. Which doesn't usually include the number stated.
Now we repeat, just instead of 3 its 2 and instead of less than its greater than.
2x + 10 + 2x + 6 > 8x
4x + 16 > 8x
16 > 4x
4 > x
So your answer is between 2 and 4.
The possible lengths of the sides of the original square (x) any value between 4 cm and 8 cm, inclusive.
Let's denote the side length of the original square as "x" centimeters. The perimeter of the square is 4x.
When 5 cm and 3 cm are added to the length and width of the square, a rectangle with dimensions (x + 5) cm and (x + 3) cm. The perimeter of the rectangle is 2 × (x + 5) + 2 × (x + 3) = 2x + 10 + 2x + 6 = 4x + 16.
According to the given information, the perimeter of the rectangle is between twice and three times the perimeter of the original square:
2 × perimeter of square ≤ perimeter of rectangle ≤ 3 × perimeter of square
Substitute the values:
2 × 4x ≤ 4x + 16 ≤ 3 × 4x
Simplify:
8x ≤ 4x + 16 ≤ 12x
Subtract 4x from all parts:
4x ≤ 16 ≤ 8x
Now, divide all parts by 4:
x ≤ 4 ≤ 2x

In which:
[tex]\pi[/tex] is the sample proportion.z is the critical value.n is the sample size.In this problem, we have a 95% confidence level, hence[tex]\alpha = 0.95[/tex], z is the value of Z that has a p-value of [tex]\frac{1+0.95}{2} = 0.975[/tex], so the critical value is z = 1.96.

Cam went to the beach and collected seashells. when he put them into 2 piles, 3 piles, and then 5 equal piles. he didn't have any extra. when he put them into 4 piles, he had exactly 2 extra. how many seashells could cam have collected?
Hey there! I'm happy to help!
We see that the number of seashells is divisible by 5, 3, and 2, but not 4. One thing I like to do to find this number is to multiply together all of the numbers it is divisible by. This product will be divisible by all of the numbers because you multiplied them all together! Let's do this below.
2×3×5=30
We see that our answer is 30, and it is divisible by 2, 3, and 5. 30 also isn't divisible by four. If you tried to do so, you would get 28 (4×7) with a remainder of two.
Therefore, Cam could have collected 30 shells.

Answer:
The answer is A. 34556
Step-by-step explanation:
The 5th term of the sequence would be a{5} = 10334.
What is a mathematical function, equation and expression?Sequence : A sequence is defined as an arrangement of numbers in a particular order.
Function : In mathematics, a function from a set X to a set Y assigns to each element of X exactly one element of Y. The set X is called the domain of the function and the set Y is called the codomain of the function
Expression : A mathematical expression is made up of terms (constants and variables) separated by mathematical operators
Equation : A mathematical equation is used to equate two expressions.
Given is the sequence -
1, 45, 104, 1034
We can write the next term as -
a{n} = 10a{n - 1} - 6
So, we can write -
a{5} = 10 x 1034 - 6
a{5} = 10340 - 6
a{5} = 10334
Therefore, the 5th term of the sequence would be a{5} = 10334.

The area of a rectangle is 44m^2, and the length of the rectangle is 3m less than twice the width. Find the dimensions of the rectangle.
Answer:
the length=8
the rectangle=5.5
Step-by-step explanation:
+)convention:
the lengt=a
the width = b => the area of the rectangle = a.b=44m^2 (1)
+) "the length of the rectangle is 3m less than twice the width"
=> 2b-a = 3 (m)
=> a=2b-3
substitute a for (1), we get
the area of the rectangle = a.b = (2b-3).b=44 m^2
=> 2b^2-3b-44=0
=> b=-4 (wrong)
=> b= 5.5 =the width
the lengt = the area of the rectangle/the width=44/5.5=8 m

Find the measure of e . A. 88 B. 46 C. 44 D. 90
Answer:
The answer is A. 88.
Step-by-step explanation:
To solve for the measure of angle ( [tex]e[/tex] ), start by noticing that 92 degrees and ( [tex]e[/tex] ) sum up to 180 degrees, which makes them supplementary angles.
Two angles are said to be supplementary angles if they add up to 180 degrees. Supplementary angles form a straight angle (180 degrees) when they are put together. In other words, angle 1 and angle 2 are supplementary, if Angle 1 + Angle 2 = 180 degrees.
Since angle 92 degrees and angle ( [tex]e[/tex] ) sum up to 180 degrees, the equation will look like [tex]92[/tex]°[tex]+e=180[/tex]°. To solve the equation, start by subtracting 92 degrees from both sides, and the equation will look like [tex]e=88[/tex]°. The final answer will be that the measure of angle ( [tex]e[/tex] ) is 88 degrees.
