The ratio of men to women in a certain factory is 3 to 4. There is 210 men

1 answer:

5 0

3 to 4.....added = 7

3/7x = 210....3/7 of all factory workers (x) are men...and men = 210
x = 210 * 7/3
x = 1470/3 = 490...so there is 490 factory workers

4/7(490) = 1960/7 = 280...and there are 280 women....because 4/7 of all factory workers are women

Martiza remembers her pin because it is between 1000 and 1500 and it is a product of two consecutive prime numbers what is her p

Anna71 [15]

Answer:

Her pin must be 1147

Step-by-step explanation:

A little trick I have up my sleeve when I have these kind of questions is that I find the square root of each number, then find what is prime.

$\sqrt{1000} = 31.6$

$\sqrt{1500} = 38.7$

Since the only prime numbers in the range of 31 and 38 is 31 and 37.

We can then multiply 31 by 37 to get 1147.

Answer:

Step-by-step explanation:

Area of a big right triangle = 1/2 * 4 * (2+2+6) = 1/2 * 4 *10 =20

Area of a left right triangle = 1/2* 2*2 = 2

Area of a right right triangle = 1/2 * 6*2 =6

Area of a square = 2*2 = 4

All together:

20+ 2+6+4 =32

Graph by hand or using a calculator to determine the solution to the given system. Put in slope-intercept form first if necessar

3241004551 [841]

The solution to the system of equations is (8, -4)

<h3>How to solve the system?</h3>

The system of equations is given as;

y = -1/4x - 2

y = 3/8x - 7

See attachment for the graph of the equations

From the attached graph, we have the point of intersection to be

(x, y) = (8, -4)

Hence, the solution to the system of equations is (8, -4)

A portion of a hiking trail slopes upward at about a 6° angle. To the nearest

DedPeter [7]

Answer:

12.6 feet

Step-by-step explanation:

we know that

The formula of slope is "rise over run", where the "rise" (means change in y, up or down) and the "run" (means change in x, left or right)

The slope is also the tangent of the angle of the opposite side (rise) divided by the adjacent side (run)

In this problem

we have

$m=tan(6^o)$

$run=120\ ft$

$rise=?$

substitute

$tan(6^o)=\frac{rise}{120}$

$rise=tan(6^o)(120)=12.6\ ft$

(NR) Natural Resources:Question 10

elena55 [62]

Answer: D) Groundwater collects only where the soil and geological features allow water to seep down into underground chambers.

In other words, as long as there are gaps to allow water through, then that would lead to underground aquifers. Another important component is the amount of rain water that happens. Sources such as rivers, lakes and streams are also a contributing factor.

Stuff like earthquakes, volcanic activity, and continental movement doesn't really have much an effect on where or how aquifers form. It's really all about the soil type and how the landscape is formed, and of course the other factors mentioned in the previous paragraph.
