What is the sum (2/5x + 5/8) + (1/5x - 1/4)? a. 3/5 x + 1/8 b. 3/5 x + 3/8 c. 3/5x + 5/8 d. 3/5x + 7/8​

Answers

Answer:

3/5x + 3/8

Step-by-step explanation:

2/5x + 5/8 + 1/5x - 1/4

1. Combine like terms so now u have

3/5x + 3/8

In case you want to know how I got 3/8

You want a common denominator so

from  5/8 + 1/4, make both denominator 8

so 1 *2/ 4* 2

so now you converted the 1/4 to 2/8

So then 5/8 - 2/8 gives u 3/8 and that's how i got 3/8

Hope this helped!

find (4.54×10^8)-(3.98×10^8)

Answers

Answer:

[tex]5.6 *10^7[/tex]

Step-by-step explanation:

Given

[tex](4.54*10^8)-(3.98*10^8)[/tex]

Required

Solve

[tex](4.54*10^8)-(3.98*10^8)[/tex]

Apply distributive law of algebra

[tex](4.54 - 3.98) *10^8[/tex]

Evaluate the expression in bracket

[tex](0.56) *10^8[/tex]

Remove bracket

[tex]0.56 *10^8[/tex]

When a number is in standard form: [tex]a * 10^n[/tex]

The value of a must be: [tex]1 \le a \le 10[/tex]

So, the expression becomes:

[tex]5.6 *10^{-1}*10^8[/tex]

Apply law of indices

[tex]5.6 *10^{-1+8}[/tex]

[tex]5.6 *10^7[/tex]

Write 3/5 as a division

Answers

Answer:

3/5 as a division is 0.6

Step-by-step explanation:

To write a fraction as a division, we basically divide the values, since the fraction represents a division.

In this question:

We want 3 divided by 5.

3 is less than 5, so we can multiply 3 by 10(getting 30), and adding a 0 to the quotient.

So now 0.(30/5) = 0.6, which means that 3/5 as a division is 0.6.

1- is -12.17 a integer?
2- 5/5 an integer?
3- 485.84 an integer?
4 - -16/13 an integer?

Answers

Answers:

No, it is not an integer due to the decimal portion 0.17; integers are either positive or negative whole numbers. Zero is included as well.Yes it is an integer because 5/5 = 1 which has no decimal or fractional parts.No, it is not an integer for similar reasoning as problem 1. The 0.84 decimal portion is why we don't have an integer.No, it is not an integer because -16/13 = -1.2308 approximately, and we don't have a negative whole number here.

A ladder rests against the top of a wall. The head of a person 6 feet tall just touches the ladder the person is 9' from the wall and 6' from the foot of the ladder. find the height of the wall​

Answers

Answer:

15 ft

Step-by-step explanation:

Let the height of the wall be represented bad x

Applying the theorem of similarity, we would have the following equation:

[tex] \frac{x}{6} = \frac{9 + 6}{6} [/tex]

[tex] \frac{x}{6} = \frac{15}{6} [/tex]

[tex] \frac{x}{6} = \frac{5}{2} [/tex]

Cross multiply

[tex] x*2 = 5*6 [/tex]

2x = 30

Divide both sides by 2

x = 15

Thus, the height of the wall = 15 ft

#1 would be 12 cm as the actual length of the thermos! This is because the scale given is 1:3 right? if you find what number 1 is multiplied by to get 3, you will obviously have 3. then, the given length of the thermos would be multiplied by 3, so it would be 3 x 4, which would be 12!

Which of the following graphs represents the solution set for y< -2x – 4? ​

Answers

Given:

The inequality is [tex]y<-2x-4[/tex].

To find:

The graph of the given inequality.

Solution:

The inequality is

[tex]y<-2x-4[/tex]

The related equation is

[tex]y=-2x-4[/tex]

For x=0,

[tex]y=-2(0)-4[/tex]

[tex]y=0-4[/tex]

[tex]y=-4[/tex]

For y=0,

[tex]0=-2x-4[/tex]

[tex]4=-2x[/tex]

[tex]\dfrac{4}{-2}=x[/tex]

[tex]-2=x[/tex]

So, the related line passes through two points (0,-4) and (-2,0).

Sign of inequality is <, so the related line is a dotted line and shaded region is below the related line.

Therefore, the correct option is B.

R= radius. Radius is half of the diameter, and d= 20. This means that radius = 10. Now we have a full formula to work with.2*Pi*10.
Substitute 3.14 for pi.
3.14 * 10 = 31.4.
31.4*2 = 62.8.
62.8 rounded equals 63.

83 in.^2

Step-by-step explanation:

The entire polygon consists of a rectangle with length 8 in. and width 5 in., a triangle with base 8 in. and height 7 in., and another triangle with base 5 in. and height 6 in.

The total are is the sum of the area of the rectangle and the two triangles.

area = area of rectangle + area of first triangle + area of second triangle

area = LW + bh/2 (for the first triangle) + bh/2 (for the second triangle)

area = 8 in. * 5 in. + 8 in. * 7 in. / 2 + 5 in. * 6 in. / 2

area = 40 in.^2 + 28 in.^2 + 15 in.^2

area = 83 in.^2

The value of the function (f +g) (x) will be (f +g) (x) = 4x³ – 2x² + 6x + 1. Then the correct option is B.

What is a function?

A statement, principle, or policy that creates the link between two variables is known as a function. Functions are found all across mathematics and are required for the creation of complex relationships.

The functions are given below.

f(x) = 3x² + 6x – 5

g(x) = 4x³ – 5x² + 6

Then the value of the function (f +g) (x) will be

(f +g) (x) = f(x) + g(x)

(f +g) (x) = 3x² + 6x – 5 + 4x³ – 5x² + 6

(f +g) (x) = 4x³ – 2x² + 6x + 1

The value of the function (f +g) (x) will be (f +g) (x) = 4x³ – 2x² + 6x + 1. Then the correct option is B.
