Answer:

multiple answers below

Step-by-step explanation:

a = 8.6

b = 4.5

c = 9.71

formula for area :: a = b*h / 2

8.6 * 4.5 = 38.7 / 2 = 19.35

perimeter = a+b+c= 8.6 + 4.5 + 9.71 = 22.81

type = right angle ??

Answer:

The axis of symmetry of a parabola is a line about which the parabola is symmetrical.

Step-by-step explanation:

The axis of symmetry of a parabola is a line about which the parabola is symmetrical. When the parabola is vertical, the line of symmetry is vertical. When a quadratic function is graphed in the coordinate plane, the resulting parabola and corresponding axis of symmetry are vertical.

Answer:

[tex]G=93\ to\ 147[/tex]

Step-by-step explanation:

From the question we are told that

Mean [tex]x= 120[/tex]  

Standard deviation [tex]\sigma= 9[/tex]

Percentage for men =99.75%

Generally the empirical rule 68%,95% and 99.7% of data value lay b/w 1,2,3 standard deviation of mean  

Standard deviation n= 9

Mean x= 120

Generally the interval  of systolic blood pressure for middle 99.7 of male G is mathematically given as

[tex]G=Mean \pm 3* \sigma[/tex]

[tex]G=120 \pm 3*9[/tex]

[tex]G=93\ to\ 147[/tex]

Answer: largest is 4.21.

Answer:

L=74

W=77

Step-by-step explanation:

Answer:

L=74 and W=77

Step-by-step explanation:

first the area of a rectangle is length of breath

A=L X W

4514= L X 61

61L=4514

L=4514/61

L=74m

b. perimeter =2(L + W)

338=2*92+ 2W

338=184+2W

2W=338-184

2W=154

W=154/2

W=74

Answer:

Step-by-step explanation:

Formula:

r = √[ (3 * v) / (π * h) ]

s.a=C.A xH

v of n.o.2 =lxwxh

Step-by-step explanation:

v of no.3=πr2h and s.a=πdh

no.1=area of cross section x area of all faces and v=area of cross section x length

try those ones

The answer is: 15m + 20n

Answer:  -2/3

i hope this helps!

Answer:

Step-by-step explanation:

To measure slope, we pick any two points on the line. Then we look at the horizontal and vertical distances between those points.

Going from the point on the left to the point on the right, the change in y is -2 and and the change in x is 3.

[tex]\sf Slope=\cfrac{rise}{run} =\cfrac{-2}{3}[/tex]

[tex]\sf = -\cfrac{2}{3}[/tex]

The slope of the line is -2/3

Answer:

Step-by-step explanation:

All the three sides are equal. So, it is equilateral triangle.

All the angles are less than 90°, so, it is acute triangle

Answer:

it's acute and equilateral

Answer:Cost of goods sold =Php125,000

Step-by-step explanation:

Profit = Cost Price-Selling Price

Also we know that

Gross Profit = Net Sales– Cost of Goods Sold

Php275,000=Php400,000– Cost of Goods Sold

Cost of Goods Sold=Php400,000-Php275,000=Php125,000

Answer:

From (0,0) and go down 1 and put a dot then down 4 and over to the right 1 and draw a line.

Step-by-step explanation:

Hope this helps have a nice day!

Answer:

T1=12 a=12 a=T1

d=9

your Arithmetic equation is Tn=a+(n-1)d

Tn=a+(n-1)d

SUBSTITUTE a and d in your equation

Tn=12+(n-1)(9)

Tn=12+9n-9

Tn=3+9n or Tn=9n+3

Answer:

1000 MM is the greatest

Step-by-step explanation:

1000 MM to CM = 100

9.7 CM and 4.7 CM are too small, therefore, we ignore them..

450 MM to CM is 45, therefore 1000 MM is the greater length

Answer:

A

Step-by-step explanation:

1,000mm=100cm

Answer:

I believe it is C.

Answer:

B

Step-by-step explanation:

because I put it on the calculator and got 0.0195, and they give us 1.95, we have to move the decimal two times in front, that is -2. So the answer is B.  

Answer:

[tex]14x + 36 = 15[/tex]

Step-by-step explanation:

Multiply both sides by LCM which is 18.

[tex]18( \frac{7}{9} )x + 2 )= \frac{5}{6} \times 18[/tex]

[tex]14x + 36 = 15[/tex]

Answer:

(i) and (ii)

Step-by-step explanation:

For a sequence to be geometric then the ratio r between consecutive terms must be common.

(1)

2, 6, 18, 54

6 ÷ 2 = 3

18 ÷ 6 = 3

54 ÷ 18 = 3

Here there is a common ratio r = 3 , then sequence is geometric

(ii)

25, 5, 1

[tex]\frac{5}{25}[/tex] = [tex]\frac{1}{5}[/tex] and [tex]\frac{a_{3} }{a_{2} }[/tex] = [tex]\frac{1}{5}[/tex]

There is a common ratio r = [tex]\frac{1}{5}[/tex] , then sequence is geometric

(iii)

1, 4, 9, 16

4 ÷ 1 = 4

9 ÷ 4 = 2.25

16 ÷ 9 = 1.777..

There is no common ratio, then sequence is not geometric

Answer:

80degrees

Step-by-step explanation:

Find the diagram attached

From the diagram, the opposite angle of the parallelogram are equal hence;

5x= 3x+40

5x - 3x = 40

2x = 40

x = 40/2

x = 20degrees

Also <M + <N = 180

<M + 5x = 180

<M + 5(20) = 180

<M + 100 = 180

<M = 180-100

<M = 80degrees

Hence the measure of angle M is 80degrees

Answer:

80
