[tex]\Huge\boxed{240ft^2}[/tex]
Step-by-step explanation:
Hello There!
The figure shown is a trapezoid with the following dimensions
base 1 = 12ft
base 2 = 20 ft
height = 15 ft
Given these dimensions we need to find the area
We can do this by using the area of a trapezoid formula
[tex]A=\frac{a+b}{2} h[/tex]
where a and b = bases and h = height
Knowing the dimensions all we have to do is plug in the values
[tex]A=\frac{12+20}{2} 15\\12+20=32\\\frac{32}{2} =16\\16*15=240\\A=240ft^2[/tex]
So we can conclude that the area of the floor that needs to be replaced with tile is 240 ft²
240ft squared
STEP BY STEP:
1) find the area of the square (15x12)
2) find area of triangle (8x15)/2
Add these numbers up (180+60)
Hope this helps

Solve for x. 4(3x - 5) = 7(2x + 3).
Answers
Answer:
x = -20.5
Step-by-step explanation:
Simplifying
4(3x + -5) = 7(2x + 3)
Reorder the terms:
4(-5 + 3x) = 7(2x + 3)
(-5 * 4 + 3x * 4) = 7(2x + 3)
(-20 + 12x) = 7(2x + 3)
Reorder the terms:
-20 + 12x = 7(3 + 2x)
-20 + 12x = (3 * 7 + 2x * 7)
-20 + 12x = (21 + 14x)
Solving
-20 + 12x = 21 + 14x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-14x' to each side of the equation.
-20 + 12x + -14x = 21 + 14x + -14x
Combine like terms: 12x + -14x = -2x
-20 + -2x = 21 + 14x + -14x
Combine like terms: 14x + -14x = 0
-20 + -2x = 21 + 0
-20 + -2x = 21
Add '20' to each side of the equation.
-20 + 20 + -2x = 21 + 20
Combine like terms: -20 + 20 = 0
0 + -2x = 21 + 20
-2x = 21 + 20
Combine like terms: 21 + 20 = 41
-2x = 41
Divide each side by '-2'.
x = -20.5
A transformation that maps the vertex A( 3 , 4 ) to A’ ( -4 , 3 ) is
Answers
Answer:
"A translation of 7 units to the left followed by a translation of 1 unit down".
Step-by-step explanation:
There are multiple transformations that map one point into another, here is one example that works particularly for translations, which are the simplest (and usually the most used) transformations.
Suppose that we have the point (a, b) which is transformed into (a', b')
Then we have a horizontal translation of (a' - a) units followed by a vertical translation of (b' - b) units.
(the order of the translations does not matter, is the same having first the vertical translation and then the horizontal one).
Here we have the point A (3, 4) transformed into (-4, 3)
Then we have a horizontal translation of ((-4) - 3) = -7 units followed by a vertical translation of (3 - 4) = -1 units.
Where a horizontal translation of -7 units is a translation of 7 units to the left, and a vertical translation of -1 unit is a translation of 1 unit down.
Then we can write this transformation as:
"A translation of 7 units to the left followed by a translation of 1 unit down".

Pollsters are concerned about declining levels of cooperation among persons contacted in surveys. A pollster contacts 76 people in the 18-21 age bracket and finds that 65 of them respond and 11 refuse to respond. When 281 people in the 22-29 age bracket are contacted, 263 respond and 18 refuse to respond. Assume that 1 of the 357 people is randomly selected. Find the probability of getting someone in the 22-29 age bracket or someone who agreed to respond.
Answers
Answer:
0.9692 = 96.92% probability of getting someone in the 22-29 age bracket or someone who agreed to respond.
Step-by-step explanation:
A probability is the number of desired outcomes divided by the number of total outcomes.
Find the probability of getting someone in the 22-29 age bracket or someone who agreed to respond.
357 people.
281 in the 22-29 age bracket + 65 in the 18-21 that agree to respond. So
[tex]p = \frac{281+65}{357} = 0.9692[/tex]
0.9692 = 96.92% probability of getting someone in the 22-29 age bracket or someone who agreed to respond.

Answer:
1,493,582.81 ft²
Step-by-step explanation:
The area of one triangular face is found using the formula for the area of a triangle:
A = 1/2bh
A = 1/2(755.9 ft)(610 ft) = 230,549.5 ft²
The base area is the area of a square 755.9 ft on a side:
A = s²
A = (755.9 ft)² = 571,384.81 ft²
Then the total surface area of the pyramid is the sum of the the areas of four (4) triangular faces and the area of the base.
SA = 4(230,549.5 ft²) +571,384.81 ft²
SA = 1,493,582.81 ft²

cos 2x = (√7) / 4
Step-by-step explanation:
sin x - cos x = 1/2
(sin x - cos x)² = (1/2)²
sin²x - 2 sin x cos x + cos² x = 1/4
1 - 2 sinx cosx = 1/4
2 sinx cosx = 3/4
sin 2x = 2 sinx cosx = 3/4
sin² 2x = 9/16
cos² 2x = 1 - sin² 2x = 1 - 9/16 = 7/16
cos 2x = (√7) / 4

Find the number of terms in the the following arithmetic sequence

Answers
Answer:
number of term is 21
Step-by-step explanation:
Please mark as brainliest
Answer:
21
Step-by-step explanation:
The first numbers we ever learn to count with are the ones on our fingers - 1, 2, 3, 4, and on and on and on. Wouldn't it be nice, then, if we could somehow transform this sequence into that one that's so familiar to us? If we could do that, we could find the number of terms just by looking at the last one.
Arithmetic sequences evolve predictably - we start with a specific number and continue adding another number (called the common difference) to one term to get the next.
Here, our common difference is 3, since 8 + 3 = 11, 14 + 3 = 17... you get the picture. If we ultimately want to get our sequence down to the counting numbers (1, 2, 3...) we should start by getting them down to the multiples of 3 (3, 6, 9...). To do that, we'll subtract 5 from each term in the sequence. This gets us from
8, 11, 14, 17, ... 68
to
3, 6, 9, 12, ... 63
From here, we'll divide each term by 3, finally giving us back a sequence of counting numbers:
1, 2, 3, 4, ... 21
Now, we can look at the last term sequence to find that there are 21 terms in it.

So, if you catch 100 fish on both days, that means that you have caught 200 fish. 100 on one day and 100 on the next. But, since you've caught 3 fish twice, that means that three out of 200 fish are the same and cannot be counted as new fish. So 3 from 200 is 197 fish. Hope this helped!
