5 tractors can plow a square field of side length 1,000 meters in 3.33 hours (3 hours 20 minutes)

Step-by-step explanation:

Let's find out how much each tractor can plow each hour.

[tex]\frac{600^{2} }{3*2}=60,000m^{2}[/tex] per tractor per hour

[tex]1,000^{2}=1,000,000m^{2}[/tex] is the area of the field of side length 1,000 meters

5 tractors can plow [tex]300,000m^{2}[/tex] per hour.

[tex]\frac{1,000,000}{300,000}=3.33[/tex] hours

Answer:

[tex]k=14[/tex]

Step-by-step explanation:

Given:

[tex]x^{2}+kx+49 = 0[/tex]

[tex]x = -7[/tex]

Substitution can be used to find the value of [tex]k[/tex]:

[tex](-7)^{2}+(-7)k+49 = 0[/tex]

[tex]49-7k+49 = 0[/tex]

[tex]98 -7k = 0[/tex]

[tex]k = 14[/tex]

Hope this helps :)

Answer:

The slope is 3/4 and the y-intercept is -5.

Step-by-step explanation:

Your equation is already in slope-intercept form, so all you have to do is look at it. Slope-intercept form looks like y = mx + b, where m is the slope and b is the y-intercept. Hope that helps!

Answer:

-2x^2-2x

Step-by-step e-xplanation:

−2x2−4x+2−(−6x+2)

Distribute the Negative Sign:

=−2x2−4x+2+−1(−6x+2)

=−2x2+−4x+2+−1(−6x)+(−1)(2)

=−2x2+−4x+2+6x+−2

Combine Like Terms:

=−2x2+−4x+2+6x+−2

=(−2x2)+(−4x+6x)+(2+−2)

=−2x2+2x

Answer:

Solving the expression [tex]\frac{2}{\sqrt[6]{8} }.\sqrt{2}-(-\frac{18}{\sqrt{81} } -2)[/tex] we get 6

The answer is 6.

Step-by-step explanation:

We need to find value of expression: [tex]\frac{2}{\sqrt[6]{8} }.\sqrt{2}-(-\frac{18}{\sqrt{81} } -2)[/tex]

We know that [tex]\sqrt{81}=9[/tex]

Our expression will become

[tex]\frac{2}{\sqrt[6]{8} }.\sqrt{2}-(-\frac{18}{\sqrt{81} } -2)\\=\frac{2}{\sqrt[6]{8} }.\sqrt{2}-(-\frac{18}{9 } -2)\\=\frac{2}{\sqrt[6]{8} }.\sqrt{2}-(-2 -2)\\=\frac{2}{\sqrt[6]{8} }.\sqrt{2}-(-4)\\=\frac{2}{\sqrt[6]{8} }.\sqrt{2}+4[/tex]

We can write [tex]\sqrt[6]{8}=(2^3)^{\frac{1}{6}}=(2)^{\frac{3}{6}}=2^\frac{1}{2}=\sqrt{2} \\[/tex]

Now, replacing [tex]\sqrt[6]{8}=\sqrt{2}[/tex]

[tex]=\frac{2}{\sqrt[6]{8} }.\sqrt{2}+4\\=\frac{2}{\sqrt{2} }.\sqrt{2}+4\\=2+4\\=6[/tex]

So, solving the expression [tex]\frac{2}{\sqrt[6]{8} }.\sqrt{2}-(-\frac{18}{\sqrt{81} } -2)[/tex] we get 6

Answer: c= 0.79p

Step-by-step explanation:

Divide each cost by the number of pens it have to find the constant change value.

3.95/5 = 0.79

7.90/10= 0 .79  

11.85/15 = 0.79

15.80 / 20 = 0.79

Since the constant change is 0.79  which means that for each pen it will cost you $0.79, then the equation will be  c= $0.79p  where c is the cost and p is the number of pens.

Answer:

$99

Step-by-step explanation:

Answer:

Step-by-step explanation:

The best way to solve this is to use a proportion. However, since this is a rate, we could also find the unit rate and multiply it by the number of cars Tiara is washing.

[tex]\frac{33}{3} = \frac{x}{9}[/tex]

3x = 33 x 9

3x = 297

Now, we simply divide by 3 to get $99.

We can check this by substituting the value of x in the original proportion.

3(99) = 33 x 9

297 = 297 ✅

The other way to solve this is to divide the whole expression by the number of cars to find the unit rate. In other words, how much money does she get for washing 1 car. We can then multiply this by the number of cars to get the answer.

$33/3 for 3/3 cars

$11 for 1 car

Now, we will multiply by the number of cars she washes in this question, which is 9

$11 x 9 = 99 for 1 x 9 cars

$99 for 9 cars

Again, we have the correct answer, which we have already verified by the process above. As you can see, both methods work. However, the top method is easier and since it uses algebra, is  almost foolproof, so long as the algebraic processess are followed.

w=16

Step-by-step explanation:

-5w = - 80 Divide both sides of the equation by- 5 -5w ÷(-5)= - 80 ÷ ( - 5 ) any expression divided by itself equals 1 w = - 80 ÷ ( - 5 ) = w = 16 also you should use photomath that's what I use

Answer:

Answer:

the vertex is (3,-2), the focus is (3,-7/4), and the directrix is  y=-9/4

Step-by-step explanation:

in order to find the vertex, you convert the equation into vertex form so

y=(x-3)^2-2

With this, we can find the vertex which is at (3,-2)

In order to find the focus and diretrix, we need to find the value of p

We do this by creating the equation:

x^2=4py

in this case, (x-3)^2=4p(y+2) so 4p must equal 1 so p is 1/4

In order to find the focus, we add the value of p to the y coordinate of the vertex so the focus is (3,-2+1/4) which is (3,-7/4)

In order to find the directrix, we subtract the value of p to the y coordinate of the vertex so the directrix passes through the point (3,-2-1/4) which is (3,-9/4)

When we graph this parabola, we can tell that the directrix will be in the form of y = a and since this line passes through (3,-9/4) the directrix is y=-9/4

I hope you understand this explanation.

Answer:

x = 13

Step-by-step explanation:

To solve for x, we set equations (9x - 54) and (3x + 24) equal to each other because the angles are equal

(9x - 54) = (3x + 24); add 54 to both sides

9x = 3x + 78; subtract 3x from both sides

6x = 78; now divide by 6

x = 13

Answer:

6kg pure copper and 30 kg 10% copper was mixed to give 36kg of 25% alloy

Step-by-step explanation:

Here, we want to produce 36 kg of 25% alloy

Let the Pure copper be x kg while 10% alloy be y kg

Pure copper is simply 100% copper

Thus;

x + y = 36 •••••(i)

Then;

100% of x + 10% of y = 25% of 36

= x + 0.1y = 9 •••••• ii)

From i x = 36-y

from ii, x = 9-0.1y

Equate both x

36-y = 9-0.1y

36-9 = 0.1y + y

0.9y = 27

y = 27/0.9

y = 30

x = 36-y

x = 36-30

x = 6 kg

Answer:

4.99 ft/sec

Step-by-step explanation:

1 mile = 5280 feet

3.4 miles = 17952 feet              or           (3.4 x 5280= 17952)

1 hour = 3600 seconds        (60 minutes per hour x 60 seconds per minute)

17952 feet / 3600 seconds = 4.99 feet per second
