I=PRT- interest rate formula

15=400*0.75*r -(0.75 bcz 9/12=0.75)

15/300=300r/300

r=0.05

the interest rate is 5%

Suppose the current cost of gasoline is $2.58 per gallon. Find the current price index number, using the 1975 price of 56.7 ce

AleksandrR [38]

Answer:

Current price index number = 455

Step-by-step explanation:

Given:

Current cost of gasoline = $2.58 per gallon

1975 price of gasoline = 56.7 Cents = 56.7 / 100 = $0.567 per gallon

Find:

Current price index number = ?

Computation:

Current price index number = (Current cost / Reference cost) 100

Current price index number = ($2.58 / $0.567)100

Current price index number = (4.55)100

Current price index number = 455

Find the value of the variable.

Nikolay [14]

we are given that

both sides are equal

so, their length must be equal

$HK=\sqrt{(p-1)^2+(5-2)^2}$

$HK=\sqrt{(p-1)^2+9}$

now, we can find other side

$JK=\sqrt{(p-7)^2+(5-2)^2}$

$JK=\sqrt{(p-7)^2+9}$

now, we can set them equal

$HK=JK$

$\sqrt{(p-1)^2+9}=\sqrt{(p-7)^2+9}$

now, we can take square both sides

$(p-1)^2+9=(p-7)^2+9$

now, we can solve for p

$(p-1)^2=(p-7)^2$

$p^2-2p+1=p^2-14p+49$

$-2p+1=-14p+49$

$12p=48$

$p=4$ ..............Answer

The measure of angle R is 65 degrees. Fond the measure of angle S.

loris [4]

Answer:

50

Step-by-step explanation:

If R is 65, then T must also be 65 because both of the sides are congruent. 65+65=130 and all angles on a triangle add to 180. Therefore 180-130 is 50
