Using the  system of equations x+y+z=7200, 0.04x+0.11y+0.14z=805 and z=x+y+200, the value of x=1400,y=2100 and z=3700

Given,

The equations

x+y+z=7200

0.04x+0.11y+0.14z=805

z=x+y+200

Substitute the value of z in the first and second equations

x+y+x+y+200=7200

2x+2y+200=7200

2x+2y=7000

x+y=3500   (1)

Similarly

0.04x+0.11y+0.14(x+y+200)=805

0.04x+0.11y+0.14x+0.14y+28=805

0.18x+0.25y=777

Multiply the equation by  4

0.72x+y=3108   (2)

We have to use elimination method here

Subtract the equation (1) from (2)

x-0.72x=3500-3108

0.28x=392

x=1400

Then,

x+y=3500

1400+y=3500

y=2100

z= x+y+200

z=1400+2100+200

z=3700

Hence, using the  system of equations x+y+z=7200, 0.04x+0.11y+0.14z=805 and z=x+y+200, the value of x=1400,y=2100 and z=3700

Answer:

17,070

Step-by-step explanation:

Continue to move the decimal point to the right, and it adds a zero when the decimal places are all taken.

Answer:

10,070

Step-by-step explanation:

so 10 to the power of three is 1 with three 0s

so 1000

remember 10 cubed is 10 times 10 times 10 that equals 1000

then 1000 times 17.07 is 17070

this is a 2 step equation

Answer:

a) S varies inversely as G

[tex]S\propto\frac{1}{G}[/tex]

or  [tex]S=\frac{K}{G}[/tex]

b) S=4 when G=7

Step-by-step explanation:

a) Write the variation.

S varies inversely as G

[tex]S\propto\frac{1}{G}[/tex]

So, We can write: [tex]S=\frac{K}{G}[/tex]

Where k is constant of proportionality

b) Find S when G is 7.

Now, if S=8, G = 3.5 we will find K

[tex]S=\frac{K}{G}\\K=SG\\K=8\times 3.5\\K=28[/tex]

So, value of K= 28

Now, find S when G is 7

[tex]S=\frac{K}{G}\\S=\frac{28}{7}\\S=4[/tex]

So, S=4 when G=7

Therefore, the slope of a line on a standard XY-plane that passes through points (1, 3) and (4,-3) is -2.

So, option (c) is correct.

Given two points are (1, 3) and (4, -3)

We need to find the slope of a line

The slope of a line (m) :

m = y₂ - y₁ / x₂ - x₁

Given (x₁, y₁) =  (1, 3) and (x₂, y₂) =  (4, -3)

Slope (m) =  y₂ - y₁ / x₂ - x₁

                = -3 - 3 / 4 - 1

                = -6 / 3

                = -2

Therefore, the slope of a line on a standard XY-plane that passes through points (1, 3) and (4,-3) is -2.

So, option (c) is correct.

Step-by-step explanation:

Each recipe of waffles requires 3/4 cups of butter

Mrs Claus has 4 1/2 cups of butter

Therefore the number of recipes which she will be able to make can be calculated as follows

= 4 1/2 ÷ 3/4

= 9/2 ÷ 3/4

= 9/2 × 4/3

= 6

Hence Mrs Claus can make 6 recipes

Note: Consider the below figure attached with this question.

Given:

[tex]a=3\sqrt{3}[/tex]

To find:

The value of b.

Solution:

In a right angled triangle,

[tex]\tan \theta = \dfrac{Perpendicular}{Base}[/tex]

For the given right angled triangle,

[tex]\tan \theta = \dfrac{a}{b}[/tex]

[tex]\tan (30^\circ) = \dfrac{3\sqrt{3}}{b}[/tex]

[tex]\dfrac{1}{\sqrt{3}} = \dfrac{3\sqrt{3}}{b}[/tex]

On cross multiplication, we get

[tex]1\times b=3\sqrt{3}\times \sqrt{3}[/tex]

[tex]b=3(3)[/tex]

[tex]b=9[/tex]

Therefore, the value of b is 9.

Answer:

1h 20m

Step-by-step explanation:

Let the total amount of work be x.

Shannon:

2h = x

1h = [tex]\frac{1}{2}[/tex]x

So basically Shannon does  [tex]\frac{1}{2}[/tex]x work per hour.

Sarah:

4h = x

1h = [tex]\frac{1}{4}[/tex]x

So basically Sarah does [tex]\frac{1}{4}[/tex]x work per hour.

Together:

1h = [tex]\frac{1}{2}[/tex]x + [tex]\frac{1}{4}[/tex]x

    = [tex]\frac{2}{4}[/tex]x + [tex]\frac{1}{4}[/tex]x

    = [tex]\frac{3}{4}[/tex]x

Amount of time spent = [tex]\frac{4}{4}[/tex]x ÷ [tex]\frac{3}{4}[/tex]x

                                     = [tex]\frac{4}{4}[/tex]x × [tex]\frac{4}{3}[/tex]x

                                     = [tex]\frac{16}{12}[/tex]h

                                     = 1[tex]\frac{4}{12}[/tex]h

                                     = 1h 20m

Answer:

4/3 hours

Step-by-step explanation:

For every hour that Sarah mows, Shannon mows twice as much. Because of this, Sarah is going to mow two times as much of the field as Shannon. You can set up an equation where x is the fraction of lawn mowed. This equation should be:

2x + x = 1 -> 3x = 1

The reason the equation is set up like this is because there is 1 whole lawn that the fraction of the lawn that Shannon mows (2x) plus the fraction of the lawn that Sarah mows (x) adds up to. You can use this equation to solve for x, which will be 1/3.

Since you know x, you can find what fraction of the lawn Shannon and Sarah mow. Since Shannon mows a fraction of 2x of the lawn, the fraction she mows will be 2*1/3 = 2/3. The fraction that Sarah mows will be x = 1/3.

Now that you know the fraction of the whole lawn that both Saran and Shannon mow, you can multiply their respective fraction by the amount of time it takes for them to mow a whole lawn. To do this for Shannon, you multiply 2/3 of the lawn by 2 hours, which gives you 4/3 hours. To do this for Sarah, you multiply 1/3 of the lawn by 4 hours, which also gives you 4/3 hours.

Answer:

B

Step-by-step explanation:

if its less than 1 it shrinks

The correct statement is; Pentagon M’N’P’Q’R is smaller than pentagon MNPQR because the scale factor is smaller than 1.

The ratio between comparable measurements of an item and a representation of that thing is known as a scale factor in arithmetic.

If a polygon is dilated by a scale factor = k

Rule to be followed as;

(x, y) → (kx, ky)

Here, k = Scale factor

If 0 < k < 1, size of the image will be reduced.

Similarly, k > 1, size of the image will be enlarged.

We are given that Pentagon MNPQR is dilated with the origin as the center of dilation to form an image M'N'P'Q'R'.

Rule used for the transformation,

(x, y) → (1/4x, 1/4y)

Here, the scale factor through which MNPQR has been dilated is 1/4.

Since, scale factor is between zero and 1/4, size of M'N'P'Q'R' will be reduced.

Therefore, the size of pentagon M'N'P'Q'R' will be 1/4 smaller than pentagon MNPQR.

Option (2) is the answer.

The complete sequence is 24, 30, 36, 42, 48, 54, 60

The nth term of an arithmetic progression is expressed according to the equation;

Tn = a + (n-1)d

where

a is the first term

n is the number of terms

d is the common difference

Determine the common difference

d = 42-b = b - 30

-b-b = -30-42

-2b = -72

b = 36

d = 36-30

d = 6

For the first term;

d = 30 - a

6 = 30 - a

a = 24

For the value of c

c = 42 + 6

c = 48

For the value of d

d = 48 + 6

d = 54

For the value of e

e = 54 + 6

e = 60

Hence the complete sequence is 24, 30, 36, 42, 48, 54, 60

Okay.

A negative exponent means we want to "flip" the term.

so we get

(1/-c^2)^1/3

When we get a fraction exponent, we want to "root" the term by that

so we get
