Answer:

He plowed 50 rows.

Step-by-step explanation:

Use proportions

1/4 = x/200

then cross multiply to find x.

4x=200  

Divide both sides by 4

x= 50

He plowed 50 rows.

Answer:

we have to put the numbers in order..

(121,122,125, 126,132),M,(135,136,136,138,140)

Step-by-step explanation:

minimum : (smallest number) = 121

Q1 : 125

Q2 (median) : (132 + 135) / 2 = 267/2 = 133.5

Q3 : 136

maximum : (largest number) = 140

I did this a long time ago so im not so sure

Answer:

Step-by-step explanation:

121 122 125 126 132 135 136 136 138 140

140 -121 =19 range

Min=121 max =140

Mean = 131.1

Median = 132+135=267/2=133.5

Answer:

Value of x --> 15°

Step-by-step explanation:

(2x + 60°) and 6x lie on a straight line. So, they form a linear pair. Their sum gives 180°.

---> (2x + 60°) + 6x = 180°

     2x + 60° + 6x = 180°

     8x + 60° = 180°

     8x = 180°- 60°

     8x = 120

      x = [tex]\frac{120}{8}[/tex]

Answer:

[81 is the missing number.]

Step-by-step explanation:

7+x=88

Let us substitute the mixing number as x.

To find a variable we must ISOLATE it.

To isolate in this situation, we must remove the 7.

We must subtract 7 from both sides, to isolate x. like this-

7-7+x=88-7

This results in,

x=81

So this missing number or (x) is equal to 81

Answer:

She has 140 coins in total.

Step-by-step explanation:

Since 7 coins is only 5% of the entire collection, 7 coins=5%. 100% is the total. So first you need to divide 100 by 5 which is 20 (100÷5=20). Next, you need to multiply 20 by 7 (20×7=140) to find out how much coins she has in total.

Step-by-step explanation:

This is calculated as:

(Number of ducks with bands × Number of examined ducks)/ Number of ducks found with leg band

= Number of ducks with bands = 12 ducks

Number of examined ducks = 20 ducks

Number of ducks found with leg band = 3 ducks

Hence:

12 × 20/3

= 240/3

= 80 ducks

Therefore, 80 ducks used the ponds

i need to get the full question, then i can help u. goodluck :)

Step-by-step explanation:

The solution is, square root of 225/16  is 15/4.

A square root of a number is a value that, when multiplied by itself, gives the number. In mathematics, a square root of a number x is a number y such that y² = x; in other words, a number y whose square is x.

For example, 4 and −4 are square roots of 16, because 4² = ² = 16.

here, we have,

225/16

=15^2/4^2

so, square root of 225/16

=√15^2/4^2

=15/4

Hence, The solution is, square root of 225/16  is 15/4.

Number of candies that are hard =15

Percentage of candies that are hard =Number of candies that are hard /   Total pieces of  candy in the box x 100

= 15/20 x 100

=75%

C. y=7

Step-by-step explanation:

guy above me was right

The horizontal asymptote of the given function  [tex]f(x) = \dfrac{14x^{3} +45}{2x^{3}+x+9}[/tex]  would be y = 7.

The line y = a is a horizontal asymptote if the function f(x) tends to 'a' from the upside of that line y = a, or from downside of that line.

The given function is

[tex]f(x) = \dfrac{14x^{3} +45}{2x^{3}+x+9}[/tex]

We need to determine the horizontal asymptote.

Horizontal asymptote;

From the given function, it is obvious that the denominator's degree is smaller than the numerator's degree.

Then, the horizontal asymptote is the y-axis.

Thus, the horizontal asymptote is y = 7.
