iris charges a fee for her consulting services plus an hourly rate that is 1 1/5 times her fee on a 7 hour job and iris charged

Veronika [31]

Based on the given problem above, here is the solution.
Given: Iris's charge: 470
1 1/5 times her fee: additional hourly rate
? = fee for an hourly rate
What we need to do first is divide 470 by 7 hours, so 470/7 = 67.143/hour.
So Iris's per hour is 67.143 without the additional rate.
Now, let's look for the 1 1/5 of 470. 1 1/5 is equal to 1.2. So 470 x 1.2 = 564.
To get the total fee of her hourly rate, we add 67.143 and 564, so Iris's hourly rate then is 631.143 or 631.14.

Hey there!!

Fill in the blanks :-

⇒ First graph the line. Locate the value of x on the x-axis. Draw a vertical line from point plotted on the x-axis to the graph of the function and a horizontal line segment from the graph of the function to the y-axis.

Find the value of f(x) when x is -2.

$f(x) = \frac{3}{2}x-4$

Remember :- f(x) is basically the y-value. It is just denoted as _f(x), it stands for function of x. Which means, the value of y, depends upon the value of x or the function of x.

Given : x = - 2

Plugging in the values :

... $f(-2) = \frac{3*(-2)}{2}-4$

... $f(-2) = \frac{-3}{1} - 4$

... $f(-2) = -7$

The last fill in the blank :

The value of y on the y-axis is the value of the function. Therefore, the value of f(x) is -7 when x is -2.

Hope it helps!!

Given m LMN = 145°, what is m XMN?

astra-53 [7]

Answer:

m∠XMN = 80°

Step-by-step explanation:

you know that:

4x + 5 + 6x - 10 = 145

solve for x:

10x - 5 = 145

10x = 150

x = 15

Use this information to solve for m∠XMN

6(15) - 10

90 - 10

m∠XMN = 80°
