don invested $ 5 000 in an account paying 5% simple interest per year for 7 years. a) how much interest will don earn at the end of 7 years?b) how much will be in Don's account at the end of 7 years?

Answers

Answer:

Results are below.

Step-by-step explanation:

Giving the following information:

Initial investment (P)= $5,000

Interest rate (r)= 5% simple interest

Number of periods (t)= 7 years

To calculate the interest earned, we need to use the following formula:

I= P*r*t

I= 5,000*0.05*7

I= $1,750

To calculate the future value of the investment, we need to use the following formula:

FV= I + P

FV= 1,750 + 5,000

FV= $6,750

How many gallons are in 48 pints?

Answers

Answer:

6

Step-by-step explanation:

Answer:

There would be 6 gallons.

Step-by-step explanation:

Within a gallon, there are 8 pints. With this in mind, create a ratio of gallons to pints to solve the problem

Gallons : Pints

1 : 8

If we were to have 48 pints, there would therefore be 6 gallons, as 48/6 --> 8

Gallons : Pints

6 : 48

Step-by-step explanation:

Since it's the mispoint

Subtract x from both sides

x - 4 = 6

Add 4 to both sides

x = 10

MB = 2x - 4

MB = 20 - 4

MB = 16

CM = x + 6

CM = 16

What is the multiplicative rate of change of the function???

Answers

answer:
i think its 2/3

The multiplicative rate of change of the function will be 2/3. Then the correct option is B.

What is an exponent?

Let a be the initial value and x be the power of the exponent function and b be the increasing factor.

The exponent is given as,

y = a(b)ˣ

At (1, 6), then we have

6 = a(b)¹

6 = ab             ...1

At (2, 4), then we have

4 = a(b)²

4 = ab             ...2

Divide equation 2 by equation 1, then we have

ab² / ab = 4 / 6

b = 2 / 3

The multiplicative rate of change of the function will be 2/3. Then the correct option is B.

9) The present ages of Juna and Jubin are in the ratio 5:8. After 4 years the sum
of their ages will be 34. Find their present ages.​

Answers

Answer:

Present age of Juna = 10 years

Present age of Jubin = 16 years

Step-by-step explanation:

Ratio of present ages = 5: 8

Let the present ages of:

Juna be 5x years and Jubin be 8x years

(where x is the common multiplier of the given ratios)

Four years after:

Juna's age = (5x + 4) years

Jubin's age = (8x + 4) years

According to the question:

(5x + 4) + (8x + 4) = 34

13x + 8 = 34

13x = 34 - 8

13x = 26

x = 26/13

x = 2

5x = 5*2 = 10 years

8x = 8*2 = 16 years

Hence,

Present age of Juna = 10 years

Present age of Jubin = 16 years

When writing a linear equation, the slope is always rise over run. When it rises (goes up) 1, it runs (goes to the side 8. So the slope is 1/8. There is no y intercept because the line passes through (0, 0). The equation is m= because the amount of money earned equals 1/8h.

if a side of a triangle is extended then exterior angle so formed equal to the sum of the two opposite interior angles

thus our equation is

[tex] \displaystyle \angle2 + {86}^{ \circ} = {135}^{ \circ} [/tex]

cancel out 86° from both sides:

[tex] \displaystyle \angle2 = {49}^{ \circ} [/tex]

what directed number is suggested by the statement "I gained 3 pounds "?​

Answers

Answer:

The directed number suggested is +3.

Step-by-step explanation:

A directed number is one that has either a positive or negative sign, so that it could be easily located on the number line. Thus, the sign shows the direction of the number. Examples are: -2, -1, +5, +6 etc.

From the given question, let the initial weight be represented by W, then:

I gained 3 pounds implies at that; 3 pounds was added to my initial weight. Thus, my present weight is my initial weight + 3 pounds.

i.e I gained 3 pounds ⇒ W + 3

So that the directed number suggested by the statement is +3.

The circumference of a circle 25.12ft. What is the circle’s diameter (take =3.14

Answers

Answer:

Diameter = 8 ft

Step-by-step explanation:

To find diameter, we need to work backwards from the formula for circumference of a circle.

Circumference = 2πr

given that π = 3.14

Circumference = 2*3.14*r

25.12 = 2*3.14*r

25.12 = 6.28 * r

4 = r

Radius = 4

Formula for Diameter =

D = 2r

D = 2*4

D = 8

Diameter = 8

Lets Check

Circumference = 2 * 3.14 * 4

Circumference = 25.12

Correct

Answer:

arc RS = 100°RS is a minor arcarc ST = 80°

Step-by-step explanation:

The measure of an arc of a circle is the same as the measure of the central angle it subtends. That is, arc RS has the same measure as central angle RPS, which is marked as 100°.

Of course, the total of all central angles, hence all arcs, of a circle is 360°. A diameter of a circle cuts the circle in half, so each semicircle has a central angle measure and arc measure of 180°.

Any arc that is more than a semicircle is called a "major" arc. If it is less than a semicircle, it is a "minor" arc. Arcs RS and ST are minor arcs.

As always in geometry, the whole is the sum of the parts, so arcs RS and ST are supplementary. They total the measure of semicircle RST, which is 180°. Then ST = 180° -RS = 180° -100° = 80°.

__

Additional comment

Usually, an arc identified only by its end points is a minor arc. If the major arc is intended, then it will either be described as "major arc RS" or a point on the major arc will be given, as "arc RTS". The measure of arc RTS is 280°.

Angle COD=40

Step-by-step explanation:

(2a+62)+ (54-a)+(5a-20)=180

6a+96=180

6a=84

a=14

Angle AOC=2(14)+62=90

Angle COD=54-14=40

Angle DOB=5(14)-20=50

Answer:

Angle COD, 40 degrees

Step-by-step explanation:

Alrighty, to start, Angle AOB is a 180 degree angle because it is a line.

Therefore, if we combine all of the variables and numbers together, we can set it equal to 180 degrees to find a.

2a+62+54-a+5a-20

6a+96=180

6a=84

a=14

Next, plug in this value into each of the given angles provided with variables and numbers:

Angle AOB:

2a+62

2(14)+62

28+62

90 degrees

Angle COD:

54-a

54-14

40 degrees

Angle DOB:

5a-20

5(14)-20

70-20

50 degrees

From this, it can be found that Angle COD has the smallest angle, with it being 40 degrees.
