Kevin is 3 times as old as
Daniel. 4 years ago, Kevin was 5 times as old as Daniel.
How old is Daniel now?

Answers

Answer 1

Answer:

Daniel is 8 years old now.

Step-by-step explanation:

From the word problem we can make the following two equations:

Let "K" be Kevin's age now and let "D" be Daniel's age now, then...

K = 3D

K - 4 = 5(D - 4)

Now we substate the value of K, and get...

K - 4 = 5(D - 4)

3D - 4 = 5(D - 4)

3D - 4 = 5D - 20

3D - 5D = - 20 + 4

- 2D = - 16

D = 8

Therefore Daniel is 8 years old now.

Find the area of a rhombus, whose diagonals are 10cm and 5.2cm
step by step ​

Answers

The area of a rhombus is p x q divided by 2.

p and q are both the diagonals of the shape.

In this case, we would do 10 x 5.2 divided by 2, which gives us 26, so your answer is 26 cm^2 (squared).

Function g is an exponential function passing through points (3,-53) and (5,-41). Which statement is true over the interval [3,5]?

Answers

Answer: The function is increasing in the given interval.

Step-by-step explanation:

The options are not given, so i will answer in a general way.

We have an exponential function g(x) such that:

g(3) = -53

and

g(5) = -41

From this we can only conclude that in the interval [3, 5] the function is increasing, because g(5) > g(3) and the general form of a exponential function is:

g(x) = A*(r)^x + C

Notice that we have two equations and 3 variables in the equation, this means that we can not find an exact solution for g(x) (we need the same number of independent equations than variables)

Then we can not conclude anything else for g(x)

Answers

Answer:

see explanation

Step-by-step explanation:

Given 2 sides of a triangle then the range of the third side x is

difference of 2 sides < x < sun of 2 sides , that is

10 - 4 < x < 10 + 4

6 < x < 14

Thus the third side can be 7, 8, 9, 10, 11, 12, 13

A glassblower can produce several sets of simple glasses in about 3 hours. When the glassblower works with
an apprentice, the job takes about 2 hours. Write an equation that can be used to find the amount of time t, in
hours, it would take for the apprentice to make the same number of sets of glasses when working alone.

Answers

Using the together rate, it is found that it would take the apprentice 6 hours to make the same number of sets of glasses when working alone.

What is the together rate?

The together rate is the sum of each separate rate.

In this problem, the rates are:

Glassblower: 1/3.Apprentice: 1/x.Together: 1/2.

Hence, applying the equation for the together rate:

[tex]\frac{1}{2} = \frac{1}{x} + \frac{1}{3}[/tex]

[tex]\frac{x + 3}{3x} = \frac{1}{2}[/tex]

[tex]2x + 6 = 3x[/tex]

[tex]x = 6[/tex]

It would take the apprentice 6 hours to make the same number of sets of glasses when working alone.

how to solve improper fraction of 4/5 - 1/4???

Answers

they aren’t improper tho?
4/5 - 1/4
find a common denominator
it would be 20
4/20 - 1/20
change the numerator too
16/20 - 5/20
it would give you 11/20

Answer:

11/20

Step-by-step explanation:

First, you have to find a common denominator between the two fractions, 4 and 5 can both equal 20 so we change the denominators to 20, 4/5 =16/20 since whatever we multiply on the bottom we multiply on the top, now for 1/4 we change it to 5/20. Now for the question, we subtract since that's what it's asking, so 16/20 - 5/20, 16 - 5 equals 11 and the denominators stay the same so the answer would be 11/20

Find the equation of the circle that has center (-4,3) and passes through 3,-3

Answers

Answer:

(x+4)^2+(y-3)^2 = 85

Step-by-step explanation:

The standard form of equation of a circle is expressed as;

(x-a)^2 + (y-b)^2 = r^2

(a, b) is the center

r iis the radius

Get the radius

Radius is the distance between the two points

r^2 = (-3-3)^2 + (3-(-4))^2

r^2 - (-6)^2+(7)^2

r^2 = 36+49

r^2 = 85

Substitute (-4, 3) and r^2 = 85 into the formula

(x-(-4))^2 + (y-3)^2 = 85

(x+4)^2+(y-3)^2 = 85

This gives the required equation

Answer: x= 4/1289 not sure if this was what you were looking for.

Step-by-step explanation:

Step 1: Subtract 143x from both sides.

1432x−3−143x=143x+1−143x

1289x−3=1

Step 2: Add 3 to both sides.

1289x−3+3=1+3

1289x=4

Step 3: Divide both sides by 1289.

1289x/1289 = 4/1289

x= 4/1289
