Daniel paid interest of 1,020 in 5years at12%per annum on a loan. Hw much did he borrow

Marat540 [252]

I = Prt
I=1020
r=0.12 (12% converted to decimal by dividing by 100)
t=5
1020=P(0.12)(5)
1020=P(0.6)
P=1700

Need help with this math

UNO [17]

Step-by-step explanation:

set up a proportion for a.

225/30=x/195. x=1462.5 milligrams daily

for b, if he gets 700 mg every 8 hours he only gets it 3 times a day. 700*3 is 2100, which means he is overdosing

Suppose quantity s is a length and quantity t is a time. Suppose the quantities v and a are defined by v = ds/dt and a = dv/dt.

finlep [7]

Answer:

a) $v = \frac{[L]}{[T]} = LT^{-1}$

b) $a = \frac{[L}{T}^{-1}]}{{T}}= L T^{-1} T^{-1}= L T^{-2}$

c) $\int v dt = s(t) = [L]=L$

d) $\int a dt = v(t) = [L][T]^{-1}=LT^{-1}$

e) $\frac{da}{dt}= \frac{[L][T]^{-2}}{T} = [L][T]^{-2} [T]^{-1} = LT^{-3}$

Step-by-step explanation:

Let define some notation:

[L]= represent longitude , [T] =represent time

And we have defined:

s(t) a position function

$v = \frac{ds}{dt}$

$a= \frac{dv}{dt}$

Part a

If we do the dimensional analysis for v we got:

$v = \frac{[L]}{[T]} = LT^{-1}$

Part b

For the acceleration we can use the result obtained from part a and we got:

$a = \frac{[L}{T}^{-1}]}{{T}}= L T^{-1} T^{-1}= L T^{-2}$

Part c

From definition if we do the integral of the velocity respect to t we got the position:

$\int v dt = s(t)$

And the dimensional analysis for the position is:

$\int v dt = s(t) = [L]=L$

Part d

The integral for the acceleration respect to the time is the velocity:

$\int a dt = v(t)$

And the dimensional analysis for the position is:

$\int a dt = v(t) = [L][T]^{-1}=LT^{-1}$

Part e

If we take the derivate respect to the acceleration and we want to find the dimensional analysis for this case we got:

$\frac{da}{dt}= \frac{[L][T]^{-2}}{T} = [L][T]^{-2} [T]^{-1} = LT^{-3}$

The school need to make $750 in order to cover all of their expenses.They estimate 200 students will come to the dance.If they m

densk [106]

9514 1404 393

Answer:

$3

Step-by-step explanation:

The cost that hasn't been covered by bake sale proceeds is ...

$750 -150 = $600

If that cost is divided among 200 students, the amount each student needs to pay is ...

$600/(200 students) = $3/student

They need to charge $3 per ticket.

Trapezoid A'B'C'D' is the image of trapezoid ABCD under a rigid transformation.

lana [24]

Answer:

Step-by-step explanation:

a). Trapezoid ABCD has one acute angle, one obtuse angle and two right angles.

Since, angle B is an acute angle, mark the vertex A' having acute angle.

Similarly, Obtuse angle A' for A and other vertices.

b). Rigid transformation doesn't change the size and shape of the image.

Therefore, all angles and measure of sides of ABCD will remain unchanged.

Measure of angle A' = 130°, m∠B' = 50°

m(A'D') = m(AD) = 6 units

m(C'D') = m(CD) = 4 units
