Step-by-step explanation:

let M be the midpoint of x and y

xM= (xX+xY)/2 =(0+88)2=44

yM=(Yx+yY)/2=(21_103)/2=_41

M(44,_41)

One bag of rice that weighs 4.5 pounds will have enough rice if a recipe calls for 60 ounces of rice. (1 pound = 16 ounces)

krek1111 [17]

the bag of rice weighs 4.5 pounds

Multiply 4.5 with 16 oz (as 1 lb = 16 oz)

4.5 x 16 = 72.

The bag of rice has 72 oz of rice inside.

The recipe only needs 60 oz of rice ∴ True, you will have enough, with 12 oz left over.

Five hundred sixth-grade students

AveGali [126]

Answer:

The ratio in three ways are 500 : 125 or 100 : 25 or 4 : 1

Solution:

Given that,

Five hundred sixth-grade students were surveyed

Which means,

sixth-grade students = 500

125 had traveled on an airplane

What is the ratio of total sixth-grade students to the number of students who had traveled on an airplane?

Therefore,

total sixth-grade students : students traveled on airplane = 500 : 125

Ratio = 500 : 125

Reduce to lowest terms,

Divide both sides by 5

Ratio = 100 : 25

Further reduce to simplest terms,

Divide both sides by 25

Ratio = 4 : 1

Thus the ratio in three ways are 500 : 125 or 100 : 25 or 4 : 1

Natalija [7]

Split up the interval [2, 5] into $n$ equally spaced subintervals, then consider the value of $f(x)$ at the right endpoint of each subinterval.

The length of the interval is $5-2=3$ , so the length of each subinterval would be $\dfrac3n$ . This means the first rectangle's height would be taken to be $x^2$ when $x=2+\dfrac3n$ , so that the height is $\left(2+\dfrac3n\right)^2$ , and its base would have length $\dfrac{3k}n$ . So the area under $x^2$ over the first subinterval is $\left(2+\dfrac3n\right)^2\dfrac3n$ .

Continuing in this fashion, the area under $x^2$ over the $k$ th subinterval is approximated by $\left(2+\dfrac{3k}n\right)^2\dfrac{3k}n$ , and so the Riemann approximation to the definite integral is

$\displaystyle\sum_{k=1}^n\left(2+\frac{3k}n\right)^2\frac{3k}n$

and its value is given exactly by taking $n\to\infty$ . So the answer is D (and the value of the integral is exactly 39).

Answer:

1 to 3

Step-by-step explanation:

For every goal team A scored, team B scored 3 goals.

So when team A scores 1 goal,

Team B scores 3 goals.

1 goal, 3 goals
