What is the area of triangles in square yards

Mathematics
1 answer:
tia_tia [17]2 years ago
3 0

Answer:

37.625 square yards or 37⅝ square yards

Step-by-step explanation:

Area of the triangle = ½*base*height

Where,

base = 10¾ yd = 10.75 yds

height = 7 yds

Substitute the value of each variable into the equation:

Area = ½*10.75*7

Area = 37.625 square yards or 37⅝ square yards

jill has $9.96 in nickles,pennies, and dollar bills. she has 12 more pennies than nickles and fove fewer dollar bills than nickl
AleksandrR [38]
Number of pennies:P
Number of nickels:N
Number of dollar bills:D
P=N+12
N=D+5
1P+5N+100D=996
^given
Therefore 
P=(D+5)+12
P=D+17
Plug back into main equation
(D+17)+5(D+5)+100D=996
Combine like terms 
106D+42=996
106D=954
D=954/106=9

9 Dollar bills

N=D+5
N=(9)+5=14

14 Nickels

P=N+12
P=(14)+12=26

26 Pennies

26*1+14*5+9*100=996

Final answer:
9 Dollars
14 Nickels
26 Pennies

PLEASE HELP<br> Find the length of the missing side.
BabaBlast [244]

Answer:

use Pythagoras theorem

the missing side is base

Step-by-step explanation:

pythagoras theorem

h^2 = p^2 + b^2

73^2 = 48^2 + b^2

5329 = 2304 + b^2

5329 - 2304 = b^2

3025 = b^2

√3025 = b

55 = b

I need some help with graphing again.

To find the x intercepts, we need to put the standard form equation into factored form.

Which two numbers multiply to -8 and add to -2?

-4*2=-8

-4+2=-2

So the factored form is

(x-4)(x+2)

That means the x intercepts are at x=4,-2

So now we have the x intercepts.

To find the vertex, we need to convert the standard form equation into vertex form.

The formula of vertex form is y=a(x-h)^2+k

Since the a value in the standard form equation is 1, the a value in vertex form is also one.

The h value can be found using the formula h=\frac{-b}{2a}

Which comes out to \frac{2}{2} or 1.

To find the k value, we can just plug in what we got for h back into the equation.

(1)^2-2(1)-8=-9

So the vertex is (1,-9).

This also means the axis of symmetry is x=-1

Finally, to find the y intercept, we plug in 0 for x and solve.

(0)^2-2(0)-8=-8

So the y intercept is (0,-8).
