Answer:

  yes

Step-by-step explanation:

By the "rule of 72", the amount will be doubled in 72/I years, where I is the annual interest rate in percent. That is, it can be estimated to take 72/4 = 18 years to double the $240 investment to $480. It would take another 18 years to double it again to $960. So, to achieve a balance of $1500 will be expected to take more than 36 years. The only reasonable answer choice is the one you have selected.

The exact solution is ...

  log (1500/240)/log(1 +0.04) ≈ 46.72 years ≈ 47 years.

Answer:

A

Step-by-step explanation:

to find the inverse, there are two steps

1-interchange x and y

2-solve for y

so y=x+1/x

interchange to get x=y+1/y

and solving for y we multiply both sides by y to get xy=y+1

subtract both sides by y yielding xy-y=1

factor out y to get y(x-1)=1

then divide to get y=1/x-1

Answer:

The measure of the first angle is 50°.

Step-by-step explanation:

Let the three angles be a, b, and c.

The measure of the first angle is twice the measure of the second angle. In other words:

[tex]a=2b[/tex]

The measure of the third angle is 80° more than the measure of the second angle. In other words:

[tex]c=b+80[/tex]

And since the interior angles of a triangle must equal 180°:

[tex]a+b+c=180[/tex]

Substitute a and c:

[tex](2b)+b+(b+80)=180[/tex]

Combine like terms:

[tex]4b+80=180[/tex]

Subtract 80 from both sides:

[tex]4b=100[/tex]

And divide both sides by four:

[tex]b=25^\circ[/tex]

So, the measure of the second angle is 25°.

Since the measure of the first is twice the second, the measure of the first angle is 50°.

(And since the measure of the third is 80° than the second, the measure of the third angle is 105°.)

Answer:

3/10

Step-by-step explanation:

Find the LCM of 5 and 2.

LCM = 10

[tex]\frac{4}{5} - \frac{1}{2} = \frac{8 - 5}{10} = \frac{3}{10}[/tex]

Answer:

[tex]\frac{3}{10}[/tex]

Step-by-step explanation:

5 = 5 × 1

2 = 2 × 1

LCM = 2 × 5

10

[tex]\frac{2(4)}{2(5)} -\frac{5(1)}{5(2)}[/tex]

[tex]\frac{8}{10} -\frac{5}{10}[/tex]

[tex]\frac{3}{10}[/tex]

Answer:

first hust rotate 180 and next reflect it over x axis.

the given point (-7,3) id in second quadrant but after rotation it will be in fourth quadrant.

afterwards you have to refect that point over x-axis which gives you the image of the points on first quadrant ie. (7,1).

Step-by-step explanation:

4*1 = 4

this indicates multiplication

8/9 = 0.88888888888 which when simplified would go back to 8/9 or .889

8 "over" 9 indicates division!

Answer:

(-8,-8)

Step-by-step explanation:

Coordinates of a midpoint:

The coordinates of the midpoint of a segment is given by the mean of the coordinates of the endpoints.

In this question:

Endpoints (-16,0) and (0,-16).

x-coordinate:

[tex]\frac{-16+0}{2} = -8[/tex]

y-coordinate:

[tex]\frac{0-16}{2} = -8[/tex]

Then:

(-8,-8)

Step-by-step explanation:

Create a table of appropriate x values e.g. x = 2 and substitute into y=3x which will be y=3*2 meaning y=6 at the point x=2. Repeat with different x values until you have enough points to draw a straight line.

Answer:

H

Step-by-step explanation:

y= (1)x-3

Positive gradient, and the y intercept for the graph is -3, F is not the answer, the Y intercept is not -3.

Answer:

1. An Experimental

2. Dependent

3. Independent

Step-by-step explanation:

Considering the description of how the research was carried out, it can be concluded that This study is an example of AN EXPERIMENTAL study. This because the researcher is trying to study the effectiveness of a new drug for lowering cholesterol

The difference in cholesterol level is the DEPENDENT variable. This is because the difference in cholesterol level is what the researcher wants to determine.

The treatment with a drug or placebo is the INDEPENDENT variable. This is because this is what the researcher manipulates to determine the difference in cholesterol level which is the dependent variable in this experimental study.

Answer:

30

Step-by-step explanation:

There are 14 data points on the plot

The median is the middle value, which is between the 7th and 8th data points

Since it is even, we find the average of the 7th and 8th data points

Add the 7th and 8Th data points values and divide by 2

( 30+30)/2 = 60/2 = 30

The median is 30

Answer:

30

Step-by-step explanation:

Middle numbers are 30 and 30 so you add them and then divide by two:

[tex]\frac{30 + 30}{2}[/tex] = [tex]\frac{60}{2}[/tex]= 30

From the graph,

f(-2) = 0

and, g(-2) = 0

(ƒ − g)(−2)= f(-2)-g(-2) = 0

OPTION B is the correct answer

Answer:

63.69 meters

Step-by-step explanation:

the total perimeter of two identical semi-circular = 100+100 = 200m

d = p/π = 200/3.14 = 63.69

Answer:

A

Step-by-step explanation:

Answer:

First side is: 12cm

Second side is: 36cm

Third side is: 16cm

Step-by-step explanation:

Let x represent the shorter side

Then 3x represents the second side, and

x + 4 represents the third side.

Perimeter of three sides:

P = x + 3x + (x + 4)

Perimeter is 64, so

64 = x + 3x + (x + 4)

64 = 5x + 4

60 = 5x

12 = x

First side is x: 12cm

Second side is 3x: 3(12) = 36cm

Third side is x + 4: 12 + 4 = 16cm

Answer:

First term is 15

Step-by-step explanation:

Given data:

[tex]a_{7} =3\\d=-2[/tex]

Now,

[tex]a+6d=3.....(1)\\a_{n} =a+(n-1)d\\\\\\From equation (1)\\a+6(-2)=3\\a-12=3\\a=12+3\\a=15[/tex]

Therefore first term a =15

Correct option is (c)

Answer:

Probably "Median"

The mode doesn't really make sense,

and "mean" would probably be skewed by people who get divorced quickly

I would suggest "Median" the number of years that 1/2 of the couples are above and 1/2 below

Answer:

T T → T

Step-by-step explanation:

Given :

p = 10 > 7

q = 10 > 5

Evaluating if the statements are true :

p = 10 > 7, This is TRUE, Because 10 is truly greater Than 7

q = 10 > 5, This is TRUE, Because 10 is truly greater Than 5

The statements are both True statements :

p = True ; q = True

True and True = True

T & T = T

T T → T
