Remark
Are there ever a lot of assumptions!!
The rectangles are all the same sizethe triangles are the same sizeThe rectangles are indeed rectangles.The triangles are isosceles.The two equal sides are both equal to the width of the rectangles.Area of the rectangles
A = L * W
L = 4 m
W = 3 m
Area = 4*3 = 12
There are 3 rectangles so the total area = 3*12 = 36
Area triangles
Area = 1/2 b * h
b = 3
h = 2.6
Area = 1/2 * 2.6 * 3
Area = 1/2 7.8
But there are 2 of them so the area for the 2 is
Area = 2* 1/2 7.8
Area = 7.8
Total area = 36 + 7.8
Total area = 43.8

A trade magazine routinely checks the drive-through service times of fast-food restaurants. Upper AA 9595% confidence interval that results from examining 773773 customers in one fast-food chain's drive-through has a lower bound of 169.0169.0 seconds and an upper bound of 172.2172.2 seconds. What does this mean?
Answers
Answer:
One can be 95% confident that the drive-through service times of fast-food chain is between 169 seconds and 172 seconds.
Step-by-step explanation:
The confidence interval gives a range of value for the population mean or parameter, which is calculated from the statistic value of the data (that is sample statistic). This range gives the interval which is associated with a certain level of confidence for which the interval will contain the true value of the unknown parameter (true value). In the scenario above, the associated confidence level is 95%.Hence, we can be 95% confident that the true value will be continued with the interval (169 ; 172)

The length of the base of a rectangle is increased by 10% but the area remains unchanged. By what percent was the breadth reduced?
Answers
Answer:
9.09%
Step-by-step explanation:
Area of a rectangle = length x breadth
to determine the answer, i would use an example
Assume length = 10
breadth 20
Area = 10 x 20 = 200
If the length is increased by 10%, the new length becomes = 1.1 x 10 = 11
11 x b = 200
b = 200/11 = 18.181818
Percentage reduction = (18.181818 / 20) - 1 = 0.0909 = 9.09%
Los lados de un triángulo rectángulo tienen por medida tres números enteros consecutivos. Calcula los lados del triángulo.
Answers
Answer:
Los lados del triángulo rectángulo miden 3, 4 y 5, respectivamente.
Step-by-step explanation:
Un triángulo rectángulo puede ser descrito mediante el teorema de Pitágoras, para el caso de tres lados representando tres números enteros consecutivos, tenemos que:
[tex](n+2)^{2} = n^{2} + (n+1)^{2}[/tex] (1)
Donde [tex]n[/tex] es un número natural.
A continuación, expandimos la expresión y resolvemos:
[tex]n^{2}+4\cdot n +4 = n^{2} + n^{2} +2\cdot n + 1[/tex]
[tex]n^{2}-2\cdot n -3 = 0[/tex]
[tex](n -3) \cdot (n+1) = 0[/tex]
La única solución factible es [tex]n = 3[/tex]. En consecuencia, los lados del triángulo rectángulo miden 3, 4 y 5, respectivamente.

Laura takes 80 steps to walk across her local park.
Laura's steps are 70 centimetres long.
Her sister Kara's steps are 80 centimetres long.
How many steps does Kara take to walk across
the park?
a. 45
b.56
c.70
d.80
Answers
Answer:
c. 70
Step-by-step explanation:
Laura’s steps are 70cm, and she takes 80 steps, which would give her a total length of 5600cm. Kara’s steps are 80cm, so we have to divide 5600cm by 80cm. This means Kara takes 70 steps to walk across the park.
1. Find the area of the composite figure to the nearest hundredth.
2. Find the area of the shaded region to the nearest tenth.
Answers
Answer:
#1: 751.56 mm²
#2: 477 km²
Step-by-step explanation:
First I noted the semicircle on the left, which has a radius of 12.5 mm. The formula for finding the area of a semicircle is 1/2(πr²).
1/2(3.14 * (12.5)²)
12.5 squared is 156.25.
1/2(3.14 * 156.25)
Multiply 3.14 by 156.25 to get 490.625.
1/2(490.625)
Divide 490.625 by 2 to get 245.3125.
245.3125 mm² for the semicircle
Then, I split the rest of into a 12.5 by 25 rectangle and a 31 by 12.5 triangle.
(12.5 * 25) + 1/2(31 * 12.5)
Multiply 12.5 by 25 to get 312.5.
312.5 + 1/2(31 * 12.5)
Multiply 31 by 12.5 to get 387.5.
312.5 + 1/2(387.5)
Multiply 1/2 by 387.5 to get 193.75
312.5 + 193.75
Add 312.5 and 193.75 to get 506.25.
506.25 mm² for the rest of the figure.
Now add the two measures, and you have your answer for #1.
245.3125 + 506.25 = 751.5625 mm², which rounds to 751.56 mm².
The area of the composite figure is 751.56 mm².
Now for #2. First, find the area of the triangle.
1/2(40 * 27)
Multiply 40 by 27 to get 1080.
1/2(1080)
Multiply 1/2 by 1080.
590 km² for the triangle.
Now find the area of the circle.
3.14 * 6²
3.14 * 36
113.04 km² for the circle.
Now subtract the area of the circle from the area of the triangle.
590 - 113.04
476.96 km², which rounds to 477.0 km².
The area of the shaded region is 477 km².
Answer:
1. 745.31 mm²2. 426.96 km²Step-by-step explanation:
#1
We can separate the figure into 3 parts and sum the areas.
Semicircle with radius 12.5 mm:
A = 1/2(πr²) = 1/2(3.14*12.5²) = 245.31 mm²Rectangle with sides 12.5 mm and its double size:
A = 12.5*(2*12.5) = 312.5 mm²Triangle with height 12.5 mm and base 30 mm:
A = 1/2*(55 - 2*12.5)*12.5 = 187.5 mm²Sum of the three:
245.31 + 312.5 + 187.5 = 745.31 mm²#2
The shaded region is the difference of the areas of the triangle and the circle
Triangle:
A = 1/2*27*40 = 540 km²Circle:
A = πr² = πd²/4 = 3.14*12²/4 = 113.04 km²Shaded region:

So we will use quadratic formula and solve out for x .
[tex]\implies 6x = 2x^2 + 1 \\\\\implies 2x^2 -6x + 1 = 0 \\\\\implies x = \dfrac{-b\pm \sqrt{ b^2-4ac}}{2a} \\\\\implies x = \dfrac{ 6 \pm \sqrt{ (-6)^2-4(2)(1) }}{2(2)} \\\\\implies x = \dfrac{ 6 \pm \sqrt{ 36 - 8 }}{4} \\\\\implies x = \dfrac{ 6 \pm \sqrt{ 28}}{4} \\\\\implies \boxed{\boxed{ x = \dfrac{ 3\pm \sqrt7}{2} }}[/tex]

The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (- 8, - 42 ) and (x₂, y₂ ) = (- 3, - 17 ) ← 2 ordered pairs from the table
m = [tex]\frac{-17-(-42)}{-3-(-8)}[/tex] = [tex]\frac{-17+42}{-3+8}[/tex] = [tex]\frac{25}{5}[/tex] = 5
The line crosses the y- intercept at (0, - 2 ) , then
y = 5x - 2 → C
Answer:
C. y=5x-2
Step-by-step explanation:
Put the numbers in the x column in the x of the equation and do the same for y. Solve, and if both sides are equal, the equation is correct.
You can use any set of x and y and try each equation till you find the right one. (0,-2) would be the easiest, because you can just make x=0, but you have to test the correct equations again with a different set after. {I used (-8,-42).}
