Ryan spent 1/3 of his monthly salary for rent and 1/7 of his monthly salary for his utility bill. If $759 was left, what was his

musickatia [10]

Step-by-step explanation:

<h3>Given Information :</h3>

Ryan spent 1/3 of his monthly salary for rent and 1/7 of his monthly salary for his utility bill.
Remaining money = $759

<h3>To calculate :</h3>

His monthly salary.

<h3>Calculation :</h3>

Let us assume his monthly salary as x. According to the question,

➝ Money spent on rent + Money spent for utility bill + Remaining money = His salary

$\longrightarrow\sf {\dfrac{1}{3}x + \dfrac{1}{7}x + 759 = x} \\$

$\longrightarrow\sf {\dfrac{7x + 3x + 15939}{21}= x} \\$

$\longrightarrow\sf {\dfrac{10x+ 15939}{21}= x} \\$

$\longrightarrow\sf {10x+ 15939= 21x} \\$

$\longrightarrow\sf {15939= 21x - 10x} \\$

$\longrightarrow\sf {15939= 11x} \\$

$\longrightarrow\sf {\cancel{\dfrac{15939}{11}}= x} \\$

$\longrightarrow\underline{\boxed{\bf {1449= x}}} \\$

Therefore, his monthly income is $1449.

Jose travels 130 miles in 150 minutes. How many miles does Jose travel in 1 hour?

Mariana [72]

Answer:

52 miles

Step-by-step explanation:

We can use a ratio to solve this problem. Let put miles over time. We know that 1 hour = 60 minutes. We need to have the units the same.

130 miles x miles

-------------- = ---------------

150 minutes 60 minutes

Using cross products

130 * 60 = 150 x

Divide each side by 150

130/150 * 60 = 150x/150

52 =x

Which of the following quartic functions has x= -1 and x = -3 as its only two real zeros

Komok [63]

Answer:

f(x) = x² + 4x + 3

Step-by-step explanation:

Here in this problem, we have to find the quadratic function that has x = - 1 and x = - 3 as the only two real zeros.

So, from the above condition, we can say that (x + 1) and (x + 3) are the only two factors of the function.

Therefore, the function will be f(x) = (x + 1)(x + 3), such that if the function is zero, then the solutions will be x = - 1 and x = - 3.

Hence, f(x) = x² + 4x + 3 (Answer)

Describe a method you can use to find the area of the following shape. Provide specific details in your answer, including coordi

insens350 [35]

The area of figure ABCDEF can be computed as the sum of the areas of trapezoid ACDF and triangle ABC, less the area of trangle DEF.
trapezoid ACDF area = (1/2)(AC +DF)·(CD) = (1/2)(8+5)(6) = 39
triangle ABC area = (1/2)(AC)(2) = 8
triangle DEF area = (1/2)(DF)(2) = 5

Area of ABCDEF = (ACDF area) + (ABC area) - (DEF area) = 39 +8 -5 = 42

The actual area of ABCDEF is 42 square units.
