Answer: The closest estimate for the total amount she earned = $4,500

Step-by-step explanation:

Given: Total hours worked = 287 hours

Earning for each hour = $16

Total earning = (Total hours worked ) x (Earning for each hour)

= $ (287 x 16)

= $ 4592 ≈ $4500

The closest estimate for the total amount she earned = $4500

Answer: Then the magnitude of the force is 37.86N, and the direction is 54.35°

Step-by-step explanation:

We can write the forces as vectors.

We know that Annie pushes with a magnitude of 80N in a direction of 133° (Remember that the angles are always measured from the x-axis)

The components of this force, (Ax, Ay), are then:

Ax = 80N*cos(133°)

Ay = 80N*sin(133°)

And we know that Josie pushes with a magnitude of 95N in direction of 290°

The components of this force, (Jx, Jy), are:

Jx = 95N*cos(290°)

Jy = 95N*sin(290°)

When we add these forces, the total force acting on the ball is:

F = (80N*cos(133°) ,  80N*sin(133°)) + (95N*cos(290°), 95N*sin(290°))

F = (80N*cos(133°) + 95N*cos(290°), 80N*sin(133°) + 95N*sin(290°))

Now, the third kitten wants to do a force K, in a direction θ, such that the net force acting on the ball is zero.

Then we must have that, each component of the force of the third cat (K*cos(θ)  on the x-axis and k*sin(θ) on the y-axis), is such that:

K*cos(θ) + 80N*cos(133°) + 95N*cos(290°) = 0

k*sin(θ)  + 80N*sin(133°) + 95N*sin(290°) = 0

Now we need to solve that system for k and θ

if we simplify the equations we get:

k*cos(θ) - 22.07N = 0

k*sin(θ)  -30.76N  = 0

Now we can rewrite them as:

k*cos(θ) = 22.07N

k*sin(θ)   = 30.76N  

Now we can take the quotiet between both equations to get:

(k*sin(θ))/(k*cos(θ)) = 30.76N/22.07N

Tan(θ) = 1.394

θ = Atan(1.394) = 54.35°

Now that we know the angle, we can find the value of the magnitude k, by using one of the two equations of the system:

k*cos(54.35°) = 22.07N

k = 22.07N/cos(54.35°) = 37.86N

Then the magnitude of this force is 37.86N, and the direction is 54.35°

Answer:

x = 15

Step-by-step explanation:

Given

See attachment

Required

Find x

The figure in the attachment is a quadrilateral and the angles in a quadrilateral add up to 360.

So, we have:

90 + 6x + 5+ 10x - 40 + 4x + 5 = 360

Collect like terms

6x + 10x + 4x = 360 - 90 - 5 + 40 - 5

20x = 300

Divide both sides by 20

x = 15

Hence, the value of x is 15

-4 is an integer however NOT a whole number.

Step-by-step explanation:

Integer include numbers that can be written as a fraction(whole number) and their negative selfs. So: 1,2,3,4... and -1,-2,-3,-4...

Whole numbers are numbers that can be written as a fraction but do not include negative, so any number like: 1,2,3,4... but it can't be negative.

The answer is

J) 334.06

Step-by-step explanation:

We know the rate is 1.5 inch an hour

So 1.5*2.54 is 3.81

Now 3.81 cm every hour

24 hours a day

3.81*24=91.44

Now 91.44 cm A day

1 Year or 365 days

91.44*365= 33375.6cm a year

now we also need to add the extra 12 inches in the beginning

12*2.54=30.48cm

Now add those 2

33375.6+30.48= 33406.08

now the answer asked for meters so we divide 33406.09/100

you’ll get 334.06 or J

Answer:

y= 3 + 3/4x sooooooo 3/4 is the slope... I think

Answer:

3/4

Step-by-step explanation:

You can use the x- and y--intercepts since they are easy-to-read points.

x-intercept: (-4, 0)

y-intercept: (0, 3)

To go from (-4, 0) to (0, 3), go up 3 and right 4. That is a rise of 3 and a run of 4.

slope = rise/run = 3/4

Answer: slope = 3/4

D. -6m²n² + 10m²n + 8mn² - 10mn

Step-by-step explanation:

(-7mn + 8mn² - 8m²n²) + (10m²n + 2m²n² - 3mn)

Apply the distributive property to remove the parentheses

-7mn + 8mn² - 8m²n² + 10m²n + 2m²n² - 3mn

Combine like terms together and arrange in standard form

-7mn + 8mn² - 8m²n² + 10m²n + 2m²n² - 3mn

-8m²n² + 2m²n² + 10m²n + 8mn² - 7mn - 3mn

-6m²n² + 10m²n + 8mn² - 10mn

Answer:

$0.342 ; 34.2 cents

Step-by-step explanation:

Given that:

Share price fell by 76% in past year :

current price per share = $0.45

Drop in price of share in past year :

76% of current price

0.76 * $0.45

= $0.342

Price dropped by $0.342 per share

In cent, 0.342 * 100 = 34.2 cents

Question:

Jesse and Amir were assigned the same book to read. Jesse started reading on Saturday, and he is reading 30 pages a day. Amir didn't start until Sunday, but he is reading 35 pages a day.

How many days will it take Amir to catch up to Jesse, and how many pages will they each have read?

Write an equation to represent the number of pages Amir has read. Use x to represent the number of days Amir has been reading and y to represent the number of pages he has read.

Answer:

It will take 6 days

Step-by-step explanation:

For Jesse:

[tex]Rate = 30\ pages/day[/tex]

This implies that Jesse will cover 30y in y days

For Amir:

[tex]Rate = 35\ pages/day[/tex]

This implies that Amir will cover 35x in x days

Because Amir starts a day later,

[tex]y = x + 1[/tex]

So, we have the following equations:

[tex]Jesse = 30y[/tex]

[tex]Amir= 35x[/tex]

[tex]y = x + 1[/tex]

To get the number of days when they read the same number of pages, we have:

[tex]Jesse = Amir[/tex]

Substitute values for Jesse and Amir

[tex]30y = 35x[/tex]

Substitute x + 1 for y

[tex]30(x+1) = 35x[/tex]

Open bracket

[tex]30x+30 = 35x[/tex]

Collect Like Terms

[tex]30 = 35x-30x[/tex]

[tex]30 = 5x[/tex]

Solve for x

[tex]\frac{30}{5} = \frac{5x}{5}[/tex]

[tex]\frac{30}{5} = x[/tex]

[tex]6 = x[/tex]

[tex]x = 6[/tex]

The length of the triangle ABC is given by the equation x = 5

If two triangles' corresponding angles are congruent and their corresponding sides are proportional, they are said to be similar triangles. In other words, similar triangles have the same shape but may or may not be the same size. The triangles are congruent if their corresponding sides are also of identical length.

Corresponding sides of similar triangles are in the same ratio. The ratio of area of similar triangles is the same as the ratio of the square of any pair of their corresponding sides

Given data ,

Let the first triangle be represented as ABC

Let the second triangle be represented as CDE

The measure of side AB = 2.5

The measure of side AC = x

The measure of side CE = 7

The measure of side ED = 3.5

Now , the two triangles are similar

So , corresponding sides of similar triangles are in the same ratio

Substituting the values in the equation , we get

AC / AB = CE / ED

On simplifying the equation , we get

x / 2.5 = 7 / 3.5

Multiply by 2.5 on both sides of the equation , we get

x = ( 2.5 x 7 ) / 3.5

x = 2.5 x 2

x = 5

Therefore , the value of x is 5

Hence , the measure of side x = 5
