Answer:

Step-by-step explanation:

If the amount is equal and each is 20% = $12, then total is:

Correct choice is D

Answer:

60.00

Step-by-step explanation:

20% of 60 = 12 which equals the amount of money Peter has.

So, at $60, he has 20% and $12.00

Answer:

26%

Step-by-step explanation:

How can we turn a fraction into a percentage well if 1.00 is 100% and 0.90 is 90% we can see that we can easily convert between decimal and percents. The fraction 13/50 is the same thing as 13 divided by 50 which is 0.26. So our answer is 26%

Answer: 26%

Step-by-step explanation:

13/50 = 26/100 =26%

Answer:

m > 7

Step-by-step explanation:

[tex] - 99 > 5 - 8(m + 6)[/tex]

[tex] - 8(m + 6) = - 8m - 8 \times 6[/tex]

[tex] = - 8m - 48[/tex]

[tex] - 99 > 5 - 8m - 48[/tex]

[tex]5 - 48 = - (48 - 5) = - 43[/tex]

[tex] - 99 > - 43 - 8m[/tex]

[tex] - 99 + 8m > - 43[/tex]

[tex]8m > - 43 + 99[/tex]

[tex]8m > 56[/tex]

[tex] = m > 7[/tex]

Answer:

There is no solution

Step-by-step explanation:

[tex]5(x + 3) - 2 = 2 + 5x + 9[/tex]

[tex]5x+15-2-2-5x-9=0\\15-13=0\\2=0[/tex]

There is no solution

because 2=0 is not possible.

→5(x + 3) - 2 = 2 + 5x + 9

→5x+15-2 = 11+5x

→5x-5x = 11-13

→x = -2

Answer:

the answer for this question is 2

Answer:

2 : 1

Step-by-step explanation:

→ Convert 1.4 m into cm

1.4 × 100 = 140 cm

→ Find the larger number between 140 and 70

140

→ Put into ratio format

140 : 70

→ Simplify

2 : 1

Answer:

[tex]y+9=-5(x+6)[/tex]

Step-by-step explanation:

We are being asked to write the equation in point-slope form:

[tex]y-y_1=m(x-x_1)[/tex] where m = slope and the first point = [tex](x_1,y_1)[/tex]

In this case, the slope is -5 and the point is [tex](-6,-9)[/tex] so the equation will be:

[tex]y+9=-5(x+6)[/tex]

Answer: x= 19/21.

Step-by-step explanation:

We can expand the expression to:

28x - 8x^2 - 35 + 10x -4x + 8x^2 - 4 + 8x = -1

We can then cancel the - 8x^2 and the + 8x^2 and simplify further by adding like terms:

38x - 35 + 4x -4 = -1 --> 42x - 39 = -1

We can then add 39 on both sides:

42x = 38

We can then divide both sides by the GCF (greatest common factor), 2:

21x = 19

We divide both sides by 21:

x = 19/21

Answer:

- 20x² + 26x + 8

Step-by-step explanation:

Given

4(2x³ - 5x² + 8x + 2) - 6x - 8x³ ← distribute parenthesis by 4

= 8x³ - 20x² + 32x + 8 - 6x - 8x³ ← collect like terms

= - 20x² + 26x + 8

Answer: 22 weeks to gain $312.

Step-by-step explanation:

Let w be the number of weeks.

Equation: 48 + 12w  

48 + 12(22)

= 48 + 264

= $312

It will take 22 weeks for Marty to gain $312.

Answer:  5*sqrt(5)

This is the same as sqrt(125).

It approximates to roughly 11.1803

=========================================================

Explanation:

Vector u is 5 units long as indicated by the notation ||u|| = 5. Some math books would say |u| = 5, and it's the same thing. The double bars are probably more fitting because it helps emphasize we're looking for the length of a vector and we're not using absolute value bars.

The second equation ||u|| = (1/2)*||v|| can be rewritten into ||v|| = 2*||u|| telling us that vector v is twice as long compared to vector u. Since vector u is 5 units long, that must mean vector v is 10 units long.

The two vectors are orthogonal, i.e. they are perpendicular. The vector u+v represents the diagonal of the rectangle as shown below in the attached image. Vector u is horizontal, v is vertical, and u+v is the diagonal. Technically we don't know where vector u is pointed along a compass (it may or may not be pointing directly east), but I find it's easier to have it set up like this. The answer will be the same regardless of where vector u is pointed. Rotations don't affect vector lengths.

We can see that vector u+v effectively breaks down component-wise into the horizontal component u and vertical component v (think of them as x and y components respectively).

Furthermore, note how there are two right triangles that form when we draw in the diagonal of the rectangle.

To find the length of vector u+v, we apply the pythagorean theorem.

a^2+b^2 = c^2

( ||u|| )^2 + ( ||v|| )^2 = ( ||u+v|| )^2

( 5 )^2 + ( 10 )^2 = x^2

25 + 100 = x^2

125 = x^2

x^2 = 125

x = sqrt(125)

x = sqrt(25*5)

x = sqrt(25)*sqrt(5)

x = 5*sqrt(5) is the length of vector u+v

In other words, ||u+v|| = 5*sqrt(5)

Keep in mind that this trick using the pythagorean theorem only works when vectors u and v are orthogonal. The process to find ||u+v|| for non-orthogonal vectors u,v is a bit more complicated.

Answer:

1,920,000,000 pounds of food per year and 3,840,000 people.

Step-by-step explanation:

1,280,000 active military members could have been farmers that produced 1,500 pounds of food per year. (1,280,000 farmers x 1,500 pounds of food = 1,920,000,000).

1,920,000,000 divided by 500 pounds of food per person is 3,840,000.

Answer:

(- 2, 3 ]

Step-by-step explanation:

parenthesis ( ) is used when the end value is not equal

brackets [ ] are used when the end value is equal

Here numbers are greater but not equal to - 2 and less than or equal to 3

(- 2, 3 ] ← is the appropriate interval notation
