Expand and simplify 3(2x + 1) +2(x + 4)

Answer:

A) 12.5 per hour. Slope: y = 12.5x

B)500x or Next - Now = 500x = 1,360

C) y = 12.5 + 360

Step-by-step explanation:

A) 360 in account, 40 hour then she has 860.

Find the unit amount so to find how much she gets per hour you have to find the unit amount.

Since she had a total of 860 but she already had 360, subtract 860 - 360 = 500. Now divide by 40: 500/40 = 12.5. (that's how much she gets per hour.)

B) Next , Now

Next she will make 500 every 40 hours so after that she'll have 1.360 in her account.

Equation: Next,Now

So it's the rate of change which will be 500 per 40 hours. so the rate of change is 500x

C) equation:

Rate of change 12.5 per hour

Y- intercept is 360 since that's what she had in her account so,

y = 12.5x + 360

Answer:

10

Step-by-step explanation:

The factors of 50 are: 1, 2, 5, 10, 25, 50

The factors of 80 are: 1, 2, 4, 5, 8, 10, 16, 20, 40, 80

The factors of 260 are: 1, 2, 4, 5, 10, 13, 20, 26, 52, 65, 130, 260

In all of these numbers, we can see that 10 is common throughout and 10 is also the greatest factor all these numbers share.

Hope this helps you :)

Answer:

[tex]b = \dfrac{A}{h}[/tex]

Step-by-step explanation:

Given the formula for calculating the area of the rectangle as;

A = bh where;

b is the length of the base of the rectangle, and;

h is the height of the rectangle

Required

Make b the subject of the formula

Given

[tex]A = bh\\\\divide \ both \ sides \ by \ h\\\dfrac{A}{h} = \dfrac{bh}{h}\\ \dfrac{A}{h} = b\\Re-arrange;\\b = \dfrac{A}{h}[/tex]

Hence the value of b in terms of A and h is expressed as [tex]b = \dfrac{A}{h}[/tex]

Answer:

yes

Step-by-step explanation:

The function f(x) = x/4 represents a proportional relationship.

Proportional relationships are relationships between two variables where their ratios are equivalent.  A straight line represents a proportional relationship. Mathematically -

y = mx + b

(y - b)/x = m       [m is constant]

or

y = mx

m = y/x               [m is constant]

Given is the following function -

y = x/4

We have -

f(x) = x/4

Now, we know a straight line represents a proportional relationship. The general form of equation representing the proportional relationship is -

y = mx

where -  [m] is constant

y = x/4

y = (1/4)x

On comparing, we get -

m = 1/4

Hence, the function f(x) = x/4 represents a proportional relationship.

Therefore, the function f(x) = x/4 represents a proportional relationship.

[tex]y = {x}^{2} - x - 20[/tex]

[tex]y = (x - 5)(x + 4)[/tex]

To find the zeroes , Just need to put 0 instead of y .

[tex]0 = (x - 5)(x + 4)[/tex]

[tex](x - 5)(x + 4) = 0[/tex]

_________________________________

Hint :

[tex]a \times b = 0[/tex]

[tex]a = 0 \: \: \: or \: \: \: b = 0[/tex]

_________________________________

[tex]x - 5 = 0[/tex]

Add sides 5

[tex]x - 5 + 5 = 0 + 5[/tex]

[tex]x = 5[/tex]

Or

[tex]x + 4 = 0[/tex]

Subtract sides 4

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

[tex]x = - 4[/tex]

Thus the zeroes are :

( - 4 , 0 ) and ( 5 , 0 ) .

Given :

An airplane flying at an altitude of 2600 m is approaching an airport run away located 56 km away.

To Find :

The airplane’s angle of decent.

Solution :

Height of plane, h = 2600 m.

Horizontal distance of airplane from vertices is, d = 56 km = 56000 m.

Let, angle of depression is Ф.

So,

[tex]tan \ \phi = \dfrac{56000}{2600}\\\\tan \ \phi = 21.54\\\\\phi = 87.34^o[/tex]

Therefore, the angle of decent is 87.34°.

Hence, this is the required solution.

Answer:

7000degrees/sec

Step-by-step explanation:

The question is not properly structured. Here is the correct question.

A pitcher's arm rotates at a speed of 7 degrees per millisecond (degrees/ms) . At what speed does the pitcher's arm rotate in degrees/s?

Before we proceed, you must know that we will be applying the following conversion;

1 milliseconds = 10⁻³secs

Given

Speed of pitcher's arm in degree per milliseconds = 7deg/ms

Required

We are to express in degree/sec

Using the conversion formula above;

[tex]7deg/ms = \dfrac{7^0}{1millisecs} \\\\converting \ to \ deg/s\\7deg/ms = \dfrac{7^0}{1millisecs} \times \dfrac{1}{10^{-3}s}\\7deg/ms = \dfrac{7^0}{10^{-3}s}\\[/tex]

[tex]7deg/ms = 7^0 \times 1/0.001s\\7deg/ms = 7^0 \times 1000/s\\7deg/ms = 7000^0/sec\\[/tex]

Hence the value in degree/sec is 7000degrees/sec

Total area = area of cube + area of triangle

A = 8² + [tex]\frac{8*8}{2}[/tex] = 64 + 32 = 96 in²

Answer:

96 square feet

to find the area of a triangle the formula is

A=1/2×b×h

8×8=64

1/2×8×8=32

32+64= 96

Answer:

How you find the area of a triangle is by, multiplying  two of the sides together  then multiplying that by 1/2 or .5 . To find the perimeter of the triangle add all the three sides together!

[tex]\dfrac{1}{3}[/tex]

Step-by-step explanation:

Given length of purple line = [tex]\frac{1}{2}\ inch[/tex]

Given length of green line = [tex]\frac{1}{6}\ inch[/tex]

To find:

How much longer is the purple line than the green line ?

Solution:

To find the required length, we have to subtract the length of green line from the length of purple line.

i.e.

The required answer =

[tex]\frac{1}{2}-\frac{1}{6}\\\text{Taking LCM of 2 and 6, we get 6}\\\Rightarrow \dfrac{3-1}{6}\\\Rightarrow \dfrac{2}{6}\\\Rightarrow \bold{\dfrac{1}{3}}[/tex]

Therefore, the answer is:

Purple line is [tex]\frac{1}{3}[/tex] of an inch longer than the green line.

Answer:

123 full pages

Step-by-step explanation:

Given

[tex]Total\ Stamps = 617\ stamps[/tex]

[tex]Each\ Page = 5\ stamps[/tex]

Required

Determine the number of full page

To do this, we simply divide the total stamps by stamps in each page;

[tex]Pages = \frac{Total\ Stamps}{Each\ Page}[/tex]

[tex]Pages = \frac{617}{5}[/tex]

[tex]Pages = 123.4[/tex]

Then we record only the quotient

The quotient is the digits before the decimal

[tex]Pages = 123[/tex]

Hence, she has 123 full pages
