If a welder completed 136 out of 160 welds so far, what is the percent of welds that has been completed?

1 answer:

6 0

85%. You take the completed amount and divide it by amount you have in all. Which gives you 136 divided by 160. Which will give you .85 then you move the decimal to give you a percent of 85

A line has the following equation: y=\frac{6}{7}x+5y=

Ipatiy [6.2K]

Answer:

Step-by-step explanation:

I'm still not exactly sure what the question really is, but the level suggests that it is

y = (6/7)x + 5

Any line that is parallel to this line has a slope of 6/7

Any line that is perpendicular to this line is a little more complicated.

slope of given line * slope of perpendicular line = - 1

6/7 * perpendicular slope = - 1

Multiply by 7

6*perpendicular slope = - 7

Divide by 6

perpendicular slope = - 7/6

Authur earned $136 in three weeks. He goes back to school in one more week. He needs at least $189 to buy the new coat that he w

Nady [450]

Answer:

136+ m ≥ 189 is the required inequality : m: The earning in 4th week

Arthur needs to earn AT LEAST $53 in the fourth week to buy the coat which costs at least $189.

Step-by-step explanation:

The amount earned by Arthur in first 3 weeks = $136

The amount needed to buy a coat = AT LEAST $189

Let us assume the amount Arthur needs to earn more to buy coat = $m

⇒ $ 136 + Amount Earned in 4th week ≥ $189

⇒ 136+ m ≥ 189

The above equation is the NEEDED inequality of the given situation.

Now, solving for the value of m, we get:

136+ m ≥ 189

⇒ m ≥ 189 - 136 = 53

or, m ≥ $53

Hence, Arthur needs to earn AT LEAST $53 in the fourth week to buy the coat which costs at least 189.

The length of a rectangle is 22 feet longer than the width. the perimeter is 1616 feet. find the dimensions of the rectangle.

NemiM [27]

So we can setup variable equations for this:
so we're given that the length is 22feet longer than the width!
so as an expression length is equal to 22+w
and width as an expression is just w
so the formula for the perimeter for a rectangle is 2l+2w=perimeter
so fill it in now!
1616=2(22+w)+2w
1616=44+2w+2w
1616=44+4w
1572=4w
divide by four..
w=393
and length is simply 22 more than that as stated in the question!
so length is 415
dimensions are: 415x393
