Answer:

She would make $[tex]$580[/tex] in one work week.

Step-by-step explanation:

First, we need an equation.

345 + c = y

c stands for the commission.

y stands for the total amount of money made

So let's find out what the commission is:

5% of 4,700 = 235

c = 235

So, 345 + 235 = [tex]580[/tex]

y = [tex]580[/tex]

Answer:

580$

Step-by-step explanation:

First you have to do the 5% of 4700 because she earns the weekly salary (345) plus the 5% of the things that she sale.

(4700 · 5)/100 = 235

Then you have to add 235 plus the weekly salary

235 + 345 = 580

Answer:

C. 4/3

Step-by-step explanation:

The value of tan(2x) is -4/3

Let, 'm' be an angle then the double angle formula of tan is,

[tex]tan(2m)=\frac{2~tan(m)}{1-tan^{2}m }[/tex]

For given example,

We have cos(x) = 1/√5 and sin(x) > 0

We know, sin^2(x) + cos^(x) = 1

⇒ sin^2(x) = 1 - (1/√5)^2

⇒ sin^2(x) = 1 - (1/5)

⇒ sin^2(x) = 4/5

⇒ sin(x) = ± 2/√5

But sin(X) > 0

⇒ sin(x) = 2/√5

We know, for any angle Ф,

tan(Ф) = sin(Ф) / cos(Ф)

Hence, tan(x) = sin(x)/cos(x)

tan(x) = (2/√5) / (1/√5)

⇒ tan(x) = 2/1

⇒ tan(x) = 2

Now, using the double angle formula for tan,

[tex]\Rightarrow tan(2x)=\frac{2~tan(x)}{1-tan^{2}x }\\\\\Rightarrow tan(2x)=\frac{2\times 2}{1-(2)^{2}}\\\\ \Rightarrow tan(2x)=\frac{4}{1-4}\\\\ \Rightarrow \bold{tan(2x)=-\frac{4}{3}}[/tex]

Therefore, the value of tan(2x) is -4/3

Answer:

  x^2/9 +(y +2)^2/49 = 1

Step-by-step explanation:

For center (h, k), and x- and y-semi-axis lengths a and b, respectively, the equation is ...

  ((x -h)/a)^2 +((y -k)/b)^2 = 1

The given ellipse has center (0, -2) and semi-x-axis length 3 and semi-y-axis length 7. Thus the equation is ...

  (x/3)^2 +((y +2)/7)^2 = 1

This might conventionally be written as ...

Answer:

y = -1/2x - 4

Step-by-step explanation:

6y = -3x - 24 ---> y = -3/6x - 4 ---> y = -1/2x - 4

Answer:

See below.

Step-by-step explanation:

A(3, 4)→ A′ (-4, -3)

B(3, 2)→ B′ (-2, -3)

C(−1, 2)→ C′ (-2, 1)

The coordinates of the vertices of the image of △ABC after a reflection in the line y=−x are A'(-4,-3), B'(-2,-3), and C'(-2,1) and this can be determined by using the rules of transformation.

Given :

The triangle ABC is reflected about the line (y = -x).

The following steps can be used in order to determine the coordinates of the vertices of the image of △ABC after a reflection in the line (y = −x):

Step 1 - Let the coordinate be (x,y) so after the reflection about (y = -x) the coordinate becomes (-y,-x).

Step 2 - The coordinate A(3,4) after the reflection about (y = -x) becomes A'(-4,-3).

Step 3 - The coordinate B(3,2) after the reflection about (y = -x) becomes B'(-2,-3).

Step 4 - The coordinate C(-1,2) after the reflection about (y = -x) becomes C'(-2,1).

Answer:

XZ ≈ 14.4 cm

Step-by-step explanation:

Using the cosine ratio in the right triangle, that is

cos29° = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{YZ}{XZ}[/tex] = [tex]\frac{12.6}{XZ}[/tex] ( multiply both sides by XZ )

XZ × cos29° = 12.6 ( divide both sides by cos29° )

XZ = [tex]\frac{12.6}{cos29}[/tex] ≈ 14.4 cm ( to 3 significant figures )

Answer:

X = 5

Step-by-step explanation:

To find the solution to a problem like this remember the order of PEMDAS.

According to pemdas parenthesis comes first, do you would solve for this part of the equation by multiplying the outer number by each side inside the parenthesis

Aka 3 × X and 3 × 1

This would make your new equation

3x + 3 = 18

Then, you would try to shorten the equation by removing or adding something to both sides.

In the given equation that would be subtracting 3 by either side, leaving over

3x = 15

Lastly, to find X you would divide 3x and 15

3 ÷ 15 = 5

Therefore X = 5

Answer:

x = 5

Step-by-step explanation:

1. First we need to simplify both sides of the equation.

( 3 )( x ) + ( 3 )( 1 ) = 18 Distribute the equation.

= 3x + 3 = 18

2. Now subtract 3 from both sides.

3x + 3 − 3 = 18 − 3

3x = 15

3.  Now divide both sides by 3.

3x/3 = 15/3

x = 5

Answer:

240 miles

Step-by-step explanation:

Given that:

Charges offered by Prestige car rentals for renting a midsize vehicle:

Fixed charges = $47

Per mile charges for renting a midsize vehicle = $0.07

Charges offered by Gateway Auto for renting a midsize vehicle:

Fixed charges = $35

Per mile charges for renting a midsize vehicle = $0.12

To find:

Number of miles for which both the companies charge the same price?

Solution:

Let the number of miles for which both the companies will charge the same price = [tex]x[/tex] miles

Charges for one mile by Prestige car rentals = $0.07

Charges for [tex]x[/tex] miles by Prestige car rentals = $0.07[tex]x[/tex]

Total charges by Prestige Car rentals = $47 + $0.07[tex]x[/tex]

Charges for one mile by Gateway Auto = $0.12

Charges for [tex]x[/tex] miles by Gateway Auto = $0.12[tex]x[/tex]

Total charges by Gateway Auto = $35 + $0.12[tex]x[/tex]

As per question statement, the charges are same:

[tex]\$47 + \$0.07x = \$35 + \$0.12x\\\Rightarrow 12=0.05x\\\Rightarrow x=\dfrac{1200}{5}\\\Rightarrow \bold{x=240\ miles}[/tex]

Answer:163 bpm

Step-by-step explanation:

The running heart rate of a girl as per linear equation will be 178.7 bpm.

Linear equation is an equation where the highest power of a variable is 1.

As per given data,

The average walking heart rate of eight girls is = (66 + 72 + 74 + 78 + 80 + 84 + 86 + 88)/ 8 = 78.5 bpm.

The average running heart rate of eight girls is = (128 + 136 + 134 + 138 + 142 + 144 + 14 8 + 152)/8 = 1122/8 = 140.25 bpm.

Therefore, for walking heart rate of x, the running heart rate will be (140.25/78.5)x = 1.787x.

Hence, the linear equation between walking heart rate and running heart rate is y = 1.787x.

Now, for walking heart rate of 100 bpm of a girl, the running heart rate will be = 1.787 × 100 bpm = 1787.7 bpm.
