can someone find the answer to this please ​

Answer:

[tex]Area = 34.2cm^2[/tex]

Step-by-step explanation:

Let the three sides be a, b and c respectively.

Such that:

[tex]a = 8[/tex]

[tex]b = 9[/tex]

[tex]c= 10[/tex]

Required

Determine the area

This is calculated as:

[tex]Area = \sqrt{s(s-a)(s-b)(s-c)[/tex]

Where

[tex]s = \frac{1}{2}(a + b + c)[/tex]

Substitute values for a, b and c

[tex]s = \frac{1}{2}(8 + 9 + 10)[/tex]

[tex]s = \frac{1}{2}(27)[/tex]

[tex]s = 13.5[/tex]

Substitute values for a, b, c and s in

[tex]Area = \sqrt{s(s-a)(s-b)(s-c)[/tex]

[tex]Area = \sqrt{13.5 * (13.5 - 8)* (13.5 - 9)* (13.5 - 10)[/tex]

[tex]Area = \sqrt{13.5 * 5.5* 4.5* 3.5[/tex]

[tex]Area = \sqrt{1169.4375[/tex]

[tex]Area = 34.2[/tex] -- Approximated

Answer:

0 (I think)

Step-by-step explanation:

(1,6) (3,-6)

X1 Y1. X2 Y2

-6-6= 0

3-1=2

0/2= 0

Answer:

y=-12/2x + -6

Step-by-step explanation:

m= rise/run = y2-y1/x2-x1

m=  -6 - 6 / 3 - 1    

m= rise/run  -12/2

Answer:

the correct answer would be the 2nd one !! please make me most brainlessly!!!

Answer:

the pythagorean thereom is a^2 + b^2 = c^2

Step-by-step explanation:

to find the length of the hypotenuse use a^2 + b^2 = c^2 or b^2 + a^2 = c^2

but in order to find the length of the legs use c^2 - a^2 = b^2 or

c^2 - b^2 = a^2

Answer:

The height of the trapezoid is 6.63 units

The perimeter of the trapezoid is 38 units

Step-by-step explanation:

Whenever a geometry problem is given, it is often useful if it is sketched out. A sketch of this problem can be found in the image attached.

A)

We can see that a right-angled triangle is formed between points BED, with line BE being the height, h.

To get the dimensions of the line EB, we subtract the dimensions of DC from AB. This will give 15 -5 = 10

hence the dimensions of the righ angled triangle are

DE= h

DB = 12 (diagonal)

EB = 10

From Pythagoras' theorem,

[tex]h =\sqrt{12^2 -10^2}=6.63[/tex]

The height of the trapezoid is 6.63

B)

We can get the perimeter of the trapezoid by adding the dimensions of all four sides together.

This will be

AD + DC + CB + AB

However we can assume for this case that it is a symmetrical trapezoid, and hence AD = CB

Thus, perimeter =

2 (AD) + DC +AB

2(9) +5 +15 = 38.

The perimeter of the trapezoid is 38 units

Answer: 30 cm

Step-by-step explanation: Take note that ^2 means to the second power.

a^2 + b^2 = c^2 (hypotenuse)

18^2 + 24^2 = c^2

324 + 576 = c^2

900 = c^2

To find the length of c you have to find teh square root of 900.

√c^2 = √900

c = 30

The length of the hypotenuse is 30 cm!

Hope this helped!

Answer:

a = 2w/c/15

Step-by-step explanation:

14a = ac + 2w

ac + 2w + 14a = 0

ac + 14a = -2w

14a + a = -2w/c

15a = 2w/c

a = 2w/c/15

Yes

Answer:

i cant choose any that applies to this question because there is no picture added to it and there are no choices to choose from. If i were to solve it though, it would be; yes, he will save enough money for his vacation.

Step-by-step explanation:

I know he would have enough--and in this case more than enough, because since he's planning to save $30 for a whole year just for $50, when he could simply make $60--which is in fact more than needed for his goal-- in just 2 months. If he were to stick with his plan though, he'd make $360. I got that by multiplying 30 by 12.

Answer:

Step-by-step explanation:

Multiply -3 for x and for 5

-3x-15=27

When you have this type of equation the first thing you do is take off the parentesis

Then you pass the 15 to the other side and you get -3x= 27 +15 . After that you divide that for -3 and you get the x . In this case x= -14

Answer:

$2 + $5p = $13.25

Step-by-step explanation:

Given that:

Initial purchase = $2

Pound of sliced turkey = p

Cost per pound of sliced turkey = 5$

Total amount spent = $13.25

Jennifers purchase from grocery store :

Initial purchase + (pound of sliced turkey * cost or pound) = total amount spent

$2 + $5p = $13.25
