Step-by-step explanation:

Interest Rate = (Simple Interest × 100)/(Principal × Time).

I= 7000(.0245)(7)

I=1200.5

Answer:

1,200.5

Step-by-step explanation:

Simple interest is

I = Prt,

where I is the interest earn after t years, P is the initial money , r is the rate

I = 7000*.0245*7 = 1,200.5

Find the value of K so that line passing through the points (k,-1) and (-2,8) is parallel to the equation 3x+y=-7

Answers

Answer:

k =1

Step-by-step explanation:

3x + y = -7

y = -3x - 7

m = -3

Parallel lines have same slope

[tex]Slope = -3\\\\\dfrac{8-[-1]}{-2-k}=-3\\\\\\\dfrac{8+1}{-2-k}=-3\\\\\dfrac{9}{-2-k} = -3[/tex]

Cross multiply,

9 = -3(-2-k)

9 = 6 + 3k

9-6 = 3k

3 = 3k

3/3 = k

k = 1

The angles in a quadrilateral ABCD are A(3x+10), B(3x+4), C(x+50) and D(5x+8). Find the angles of the quadrilateral ABCD

please answer it fast..thank u

Answers

Answer:

A 8º

B 76º

C 74º

D 128º

Step-by-step explanation:

The sum of the angles is 360

(3x + 10) + (3x + 4) + (x + 50) + (5x + 8) = 360

Combine like terms

12x + 72 = 360

Subtract 72 from both sides

12x = 288

Divide both sides by 12

x = 24

--------------

A (3x+10) = 3*24 + 10 = 82

B (3x+4) = 3*24 + 4 = 76

C (x+50) = 24 + 50 = 74

D (5x+8) = 5*24 + 8 = 128

5√8, √170, 5/8, 0.62

Step-by-step explanation:

5√8 = 14.1

√170 = 13.03

5/8 = 0.625

0.62 = 0.62

Answer:

5sqrt(8), sqrt(170), 5/8, 0.62

Step-by-step explanation:

Solve any equations and put them in decimal form to make it easier to list them from biggest to smallest.

14. The supervisors of a rural county are interested in the proportion of property owners who
support the construction of a new high school for the area. Rather than contact all 7,000 of
the owners, the supervisors decide to take a random sample of 300.
(a) During each interview, the supervisor's representative asks, “Do you support the building
of a new high school for the area?” For this sample, 58% of the respondents said yes. If
the representative took a second random sample of 300 property owners, would this
second sample proportion of those who support building a new high school be exactly the
same as that found in the first sample?
(b) If the representative has increased the sample size to 600 owners, what effect would this

what is the sum of two arithmetic means between 6 and 2

pls show solutions guys!!

Answers

Answer:

Step-by-step explanation:

Let the numbers are:

6, x, y, 2

Since the sequence is arithmetic, the difference of two consecutive terms is same:

d = x - 6 = y - x = 2 - y

Therefore:

x = 6 + dy = 6 + 2d2 = 6 + 3d

The sum of the first two equations:

x + y = 6 + d + 6 + 2d = 6 + (6 + 3d)

Substitute (6 + 3d) with 2 (the third equation) to get:

x + y = 6 + 2 = 8

what is angle B and C?

Answers

Answer:

x = 42

Step-by-step explanation:

The square at ∠C means it is a right angle (90°). The sum of the angles of a triangle is 180°. Use the information to solve for ∠B.

Suppose the matrix R represents a railroad map between cities 1, 2, 3, 4, and 5.

How many different ways can you travel from city 1 to city 3 with exactly 1 connection

How many different ways can you travel from city 2 to city 5 with exactly one
connection?

Answers

Observing the given matrix we can say that:

1) The value is 4.

2) The value is 2.

So analyzing the different paths that can connect city 1 to city 3: The value is 4. It represents the number of one-stop routes between City 1 and City 3 that pass through City 2.

For the second statement we will have the value is 2. It is the number of direct routes from City 2 to City 5.

How to evaluate the expression

From the question, we have the following parameters that can be used in our computation:

1/3 by the power of 4

Express as an equation

So, we have

1/3 by the power of 4 = 1/3⁴

When expanded, we have

1/3 by the power of 4 = 1/3 * 1/3 * 1/3 * 1/3

Evaluate the products

This gives

1/3 by the power of 4 = 1/81

Hence, the solution is 1/81
