$12; 20% increase (sample answer: $1, make sure to put the dollar sign in
front of the number)

Answers

Answer: $14.40

Step-by-step explanation:

The question simply asks us to calculate the value of a 20% increase in $12. This will be:

= $12 + (20% × $12)

= $12 + (20/100 × $12)

= $12 + (0.2 × $12)

= $12 + $2.40

= $14.40

A 20% increase in $12 will give $14.40

-2/3x+9=4/3x-3=

x=6

Answer:

[tex]x=6[/tex]

Step-by-step explanation:

We have the equation:

[tex]-\frac{2}{3}x+9=\frac{4}{3}x-3[/tex]

First, we can remove the fractions by multiplying both sides by 3. Therefore:

[tex]3(-\frac{2}{3}x+9)=3(\frac{4}{3}x-3)[/tex]

Distribute:

[tex]-2x+27=4x-9[/tex]

Subtract 27 from both sides:

[tex]-2x=4x-36[/tex]

Subtract 4x from both sides:

[tex]-6x=-36[/tex]

Divide both sides by -6:

[tex]x=6[/tex]

Hence, the value of x is 6.

1/2 + z/7 = 5/14
What is Z?​

Answers

nvm thts confusing sorry

Answer:

z = -1

Step-by-step explanation:

1/2 + z/7 = 5/14

Multiply both sides of the equation by 14

7 + 2z = 5

Subtract 7

2z = -2

Divide both sides by 2

z = -1

Plug -1 in for z to check

1/2 + (-1/7) = 5/14

I was earning $47,000 per year until she received a 7% raise at the start of 2019. What will her new salary be? Write a proportion and show how you solved.

Answers

Answer:

$50,290

Step-by-step explanation:

I was earning $47,000 per year until she received a 7% raise at the start of 2019.

Step 1

We find how much 7% raise is

Hence,

7 % of $47,000

= 7/100 × $47,000

= $3290

What will her new salary be?

Her new salary is calculated as:

Last year's salary + 7% raise

= $47,000 + $3290

= $50,290

Her new salary is $50,290

a farmer harvests crops on 2/5 acre of land in 1/3 hour.
At what rate, in acres per hour, does the farmer harvest crops?
put your answer in the box

Answers

Find out how much per hour, multiply 2/5 by 3

2/5 * 3/1 = 6/5
The farm harvests 1 1/5 acres per hour

A fraction is a way to describe a part of a whole.  The rate at which the farmer is harvesting his crop is 1.2 Acres/hour.

What is a Fraction?

A fraction is a way to describe a part of a whole. such as the fraction ¼ can be described as 0.25.

Given that the farmer can harvest 2/5 acre of the land in 1/3 hours, therefore, the area in which the farmer can harvest crops in 1 hour will be thrice 2/5.

[tex]\rm Rate\ of\ harvesting = \dfrac{\text{Total land harvested}}{\text{Total time taken by the farmer}}\\\\\\\rm Rate\ of\ harvesting = \dfrac{\frac25}{\frac13} = \dfrac{2 \times 3}{1 \times 5}\\\\\\\rm Rate\ of\ harvesting = \dfrac{6}{5}\ Acres/hour = 1.2 \ Acres/hour[/tex]

Hence, the rate at which the farmer is harvesting his crop is 1.2 Acres/hour.

A plane flies at 350 mph in the direction N 40° E with a wind blowing at 40 mph in the direction S 70° E. What is the plane’s drift angle?

5.89°
6.38°
45.89°
46.38°

Answers

Answer:

The correct option is;

5.89°

Step-by-step explanation:

The speed with which the plane flies = 350 mph

The direction of flight of the plane = N 40° E

The speed with which the wind blows = 40 mph

The direction in which the wind blows = S 70° E

Therefore, we have;

The resolution of the components of the motion of the plane, given as follows;

[tex]S_{Plane}[/tex] = 350 × sin(40°)·i + 350 × cos(40°)·j

The resolution of the components of the motion of the wind, given as follows;

[tex]S_{Wind}[/tex] = 40 × sin(70°)·i - 40 × cos(70°)·j

The resultant motion of the plane is given as follows;

[tex]R_{Plane}[/tex] = 262.563·i + 254.435·j

The direction of motion of the plane = tan⁻¹(262.563/254.435) ≈ N 45.9° E

Therefore, the plane's drift = Plane's Track - Plane's Heading  = N 45.9° E - N 40° E ≈ 5.9° ≈ 5.89°

Therefore, the correct option is 5.89°.

A baby was born with a weight of 7 pounds and then began to gain 1.25 pounds per month. Write an equation for W, in terms of t, representing weight, in pounds, of the newborn baby t months after birth.

Answers

Answer:

7+1.25m=t

Step-by-step explanation:

The equation that represents the weight of the baby will be W = 1.25 t + 7.

What is a linear equation?

A connection between a number of variables results in a linear model when a graph is displayed. The variable will have a degree of one.

The linear equation is given as,

y = mx + c

Where m is the slope of the line and c is the y-intercept of the line.

A child was brought into the world with a load of 7 pounds and afterward started to acquire 1.25 pounds each month.

Let 'W' be the weight of the baby and 't' be the number of months. Then the equation is given as,

W = 1.25 t + 7

The equation that represents the weight of the baby will be W = 1.25 t + 7.

if the slope is 2x the y intercept is 12. If the slope is 4x then the y-intercept is 15 . Every time your x increases by 2 your y-intercept goes up by three. In the question, it's asking you to find out the one for the number 9. 8+2 is 10 not nine so you divide 3 by 2 and get 1.5 so 21+1.5 is 22.50
