What is the area, in square meters, of the isosceles trapezoid below? 15.8 m 5-4 m 6.6 m Answer: A = ____ m squared
Answer:
5.618773 m2
I hope that this is the answer.
Answer:
answer is 60.48 m squared
Step-by-step explanation:
use the formula
a=1/2(b1+b2)h
a=1/2(15.8+6.6)h
a=1/2(22.4*5.4)
a=1/2(120.96)
a=120.96/2
a=60.48m
Factor out the GCF from the given polynomial. 10^3 + 16^2 - 18x 10^3 + 16^2 - 18x = (Type your answer in factored form.)
Correct question is;
Factor out the GCF from the given polynomial. 10x³ + 16x² - 18x. (Type your answer in factored form.)
Answer:
GCF = 5x² + 8x - 9
Step-by-step explanation:
The given polynomial is;
10x³ + 16x² - 18x
First thing is to inspect the coefficients and see the greatest number that all three can be divided by evenly without remainder.
The greatest number is 2.
Secondly let's inspect the variables to see what we can factor out.
They all contain x. Thus, x is a factor.
Thus, we will divide each term by 2x to obtain the GCF of the polynomial.
GCF = (10x³/2x) + (16x²/2x) - (18x/2x)
GCF = 5x² + 8x - 9

The equation of the line A is 3x+2y=10.line B is parallel to line A and passes through the points (4,6).find the equation of the line B.
Answer: [tex]y=-\frac{3}{2}x+12[/tex]
Step-by-step explanation:
To find the equation of line B, we need to find the slope first, then the y-intercept. We first want to convert line A into slope-intercept form, so we can find the slope.
[tex]3x+2y=10[/tex] [subtract both sides by 3x]
[tex]2y=10-3x[/tex] [divide both sides by 2]
[tex]y=5-\frac{3}{2}x[/tex]
With the slope-intercept form of line A, we can see that the slope is [tex]-\frac{3}{2}[/tex]. We take the slope and the given point (4,6) to find the y-intercept of line B.
[tex]y=-\frac{3}{2}x+b[/tex] [plug in (4,6)]
[tex]6=-\frac{3}{2}(4)+b[/tex] [multiply]
[tex]6=-6+b[/tex] [add both sides by 6]
[tex]b=12[/tex]
With the y-intercept, we know the equation for line B is [tex]y=-\frac{3}{2}x+12[/tex].

Find the area of the object
Answer:
2π + 24 m² = 30.3 m²(3 s.f.)
Step-by-step explanation:
Area of rectangle: l x w
6 x 4 = 24 m²
Area of semicircle: πr²/2
r = 4/2 = 2
π x 2² / 2
4π / 2
2π
Total area: 2π + 24 m² = 30.3 (3 s.f.)
Evaluate each expression for n = 5. 6n + n2
Answer:
40
Step-by-step explanation:
1. Plug in the given value for n
6(5) + (5)2
2. Solve using PEMDAS
(I'm not sure if the 2 after the n is supposed to be squared, but if it was n^2 then the correct answer would be 55, I think)
30 + 10 = 40
Therefore, the answer is 40

How do you find percentages?
Step-by-step explanation:
if you have 3/4 you divide the part, 3, by the whole, 4
3 ÷ 4 = 0.75
then multiply 0.75 by 100, 75, then add a percentage sign: 75%
The graph of line p represents = x-1. If the slope of line p is multiplied by (-10)
to create liner, which statement about the graphs of the two lines is true?
A
Line r intersects line p.
B Line ris parallel to line 2.
CLine ris 10 units above line p.
D
Line ris 10 units below line p.
Answer:
A. Line r intersects line p
Step-by-step explanation:
to find the second graph multiply the slope of line p by -10
slope is 1/5 or 0.2
So,
0.2 * -10 = -2
slope of second line is -2
Graph shown
Altered line shown in blue
Line p shown in green
As you can see, they intersect and meet no other answers

hey peeps i'll give you a brainliest & 25 pts for these answers plss help a dum b b out <333
you know that your line is perpendicular to the line with equation y equals 3x + 5 right whenever a line is perpendicular to another perpendicular not parallel to the line has a negative slope of the other line for example if you had a line with slope 2 x in the line perpendicular to that would have slope -1 / 2X so then you line in your question has slope -1 / 3 x by doing the Rococo of 3 and adding a negative sign to your equation sulfur looks like this y equals negative 1 / 3 x + B where is B is a constant 3 all you have to do is solve for b is a plug in the coordinate values 6 equals x minus -2 equals one in rearrange y equals -1 / 3 x + B negative two equals negative one over three 6 plus b negative two equals negative two plus be there for me easy roast F4U equation of the line is y equals -1 / 3 x

A survey found that women's heights are normally distributed with mean 63.7 . And standard deviation 3.7 . The survey also found that men's heights are normally distributed with mean 67.5. And standard deviation 3.7. Consider an executive jet that seats six with a doorway height of 56.4. Complete parts (a) through (c) below.
Complete question :
A survey found that women's heights are normally distributed with mean 63.6 in and standard deviation 3.7 in. The survey also found that men's heights are normally distributed with mean 69.3 in and standard deviation 3.7 in. Consider an executive jet that seats six with a doorway height of 55.7 in.
1-What percentage of adult men can fit through the door without bending?
2-) Does the door design with a height of 56.35in. appear to be adequate? Why didn't the engineers design a larger door? Choose answer below
A. The door design is inadequate, because every person needs to be able to get into the aircraft without bending. There is no reason why this should not be implemented.
B. The door design is adequate, because the majority of people will be able to fit without bending. Thus, a larger door is not needed.
C. The door design is inadequate, but because the jet is relatively small and seats only six people, a much higher door would require major changes in the design and cost of the jet, making a larger height not practical.
D. The door design is adequate, because although many men will not be able to fit without bending, most women will be able to fit without bending. Thus, a larger door is not needed.
Answer:
A.) 0.135%
B.) C. The door design is inadequate, but because the jet is relatively small and seats only six people, a much higher door would require major changes in the design and cost of the jet, making a larger height not practical.
C.)
Step-by-step explanation:
Percentage of adult men that can fit the door without bending :
Obtain the Zscore :
Mean height of men, m = 67.5
Standard deviation, s = 3.7
Zscore = (x - m) / s ; where x = 56.4
Zscore = (56.4 - 67.5) / 3.7
Zscore = - 11.1 / 3.7
Zscore = - 3
P(Z < - 3) = 0.0013499 (Z probability calculator)
P(Z < - 3) = 0.0013499 * 100% = 0.13499%

Answer:
A = 254.5 mm^2
Step-by-step explanation:
The radius of this circle is 9 mm.
Using the formula A = (pi)r^2, we find the area of this particular circle to be:
A = (pi)(9 mm)^2, or
A = 254.5 mm^2
