Answer:

T = 2

Step-by-step explanation:

Fill in the given numbers and solve for T.

I = PRT/100

80 = 400·10·T/100

80 = 40T . . . . . . . . . . . . simplify

80/40 = T = 2 . . . . . . . . divide by the coefficient of T

Answer:

2 years

Step-by-step explanation:

I = 80 Rs, P = 400 Rs, R = 10 Rs

I = (P * T * R)/100

80 = 400 * T * 10/100

80 = 40 * T

T = 2 years

The relationship of the given angles are:

1. A. Adjacent

2. B. vertical

3. B. vertical

4. E. linear pair

5. C. complementary

6. D. supplementary

7. C. complementary

8. A. adjacent

9. A. adjacent

11. A. adjacent

12. C. complementary.

<h3>How to Determine the Relationship Between Angles?</h3>

Different pairs of angles are related to each other in several ways. The explanation below shows the relationship between the given angles.

1. Angles 2 and 3 share a common vertex and a common side, therefore:

<2 and <3 are: A> Adjacent

2. <3 and <4 are non-adjacent angles that share a common vertex and are opposite each other. Thus:

<3 and <4 are: B. vertical

3. <1 and <3 are: B. vertical

4. <1 and <2 lie on a straight line and are adjacent to each other. Therefore, they are a: linear pair

5. 78 + 12 = 90 degrees. Therefore, their relationship is that they are: C. complementary

6. 123 + 57 = 180. Therefore, they are: D. supplementary

7. Angles a and b form a right angle. Therefore, they are: C. complementary

8. <1 and <2 are: adjacent

9. <3 and <4 are: A. adjacent

10. 90 + 90 = 180, therefore, the angles are: D. supplementary

11. Both angles are: A. adjacent

12. 40 + 50 = 90 degrees. Therefore, the angles are: C. complementary.

Which expression is equivalent to the given expression?<br> (3m-4) (375)

Brilliant_brown [7]

9514 1404 393

Answer:

D. 81/m^7

Step-by-step explanation:

The applicable rules of exponents are ...

(ab)^c = (a^c)(b^c)

(a^b)^c = a^(bc)

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

a^-b = 1/a^b

Using these, your expression simplifies to ...

$(3m^{-4})^3(3m^5)=(3^3)(3)(m^{-4\cdot3+5})=81m^{-7}=\boxed{\dfrac{81}{m^7}}$

Here's a graph of a linear function. write the equation that describes that function.

7nadin3 [17]

Answer:

Step-by-step explanation:

slope intercept form => Y = mx + b

find m... the slope by using any two points on the line

p1 = (0,5) by inspection

p2=(4,6) by inspection

find m = y2-y1 / x2-x1

m = 6 - 5 / 4 - 0

m =1 / 4

then use the slope intercept formula

y = 1/4x + 5 for your answer. we know b = 5 b/c thats where the line crosses the y axis.

y = $\frac{1}{4}$ x + 5 is the answer

Given:

The graph of a proportional relationship.

To find:

The constant of proportionality, the value of y when x is 24 and the value of x when y is 108.

Solution:

If y is directly proportional to x, then

$y\propto x$

$y=kx$ ...(i)

Where, k is the constant of proportionality.

The graph of proportional relationship passes through the point (5,15).

Substituting x=5 and y=15 in (i), we get

$15=k(5)$

$\dfrac{15}{5}=k$

$3=k$

Therefore, the constant of proportionality is 3.

Substituting k=3 in (i) to get the equation of the proportional relationship.

$y=3x$ ...(ii)

Substituting x=24 in (ii), we get

$y=3(24)$

$y=72$

Therefore, the value of y is 72 when x is 24.

Substituting y=108 in (ii), we get

$108=3x$

$\dfrac{108}{3}=y$

$36=y$

Therefore, the value of x is 36 when y is 108.
