You have a base that is 8x8 and the slant height of the triangle is 22.

This is the formula, L=1/2Ph

H = 22 Meters

1. P=2L+2W -> 2(8)+2(8) = 32 meters

2. L= 1/2(32)(22) = 352 meters squared :)

8/f = 56/105 what is f?

svetlana [45]

8/15 = 56/105

This may be solved using proportion.
a/b = c/d
ad = bc where cross products are equal.

a = 8
b = f
c = 56
d = 105

ad = bc
8*105 = f*56
840 = 56f
840/56 = 56f/56
f = 15

56 ÷ 7 = 8
105 ÷ 7 = 15

Brian invests £1800 into his bank account.

SVEN [57.7K]

Step-by-step explanation:

$\underline{ \underline{ \text{Given}}} :$

Principal ( P ) = £ 1800
Rate ( R ) = 5%
Time ( T ) = 3 years

$\underline{ \underline{ \text{To \: find}}} :$

Total amount

$\underline{ \underline{ \text{Solution}}}:$

First , finding the amount of interest :

$\boxed{ \sf{Interest = \frac{PTR}{100}}}$

⇢ $\sf{Interest = \frac{1800 \times 5 \times 3}{100}}$

⇢ $\sf{Interest = \frac{27000}{100}}$

⇢ $\sf{Interest = £ 270}$

Now , Finding the total amount :

$\boxed {\sf{Total \: amount = Principal + Interest}}$

⇢ $\sf{Total \: amount = 1800 + 270}$

⇢ $\sf{Total \: amount = \: £ 2070}$

$\red{\boxed{ \boxed{ \tt{Our \: final \: answer : brian \: will \: have £ 2070 \: after \: 3 \: year.}}}}$

2m=p-q/r solve for r

Oduvanchick [21]

To solve for r, you would start by subtracting p from both sides.

2m - p = -q/r

Multiply everything by r.

2mr - pr = -q

Factor r out of the left side of the equation.

r(2m - p) = -q

Divide both sides by (2m - p).

r = $\frac{-q}{2m-p} = \frac{q}{2m + p}$ .
