For the school recycling project, the seventh grade collected sixteen more than five times as many cans as the eighth grade. The

seventh grade collected 251 cans. Select all of the equations that can be used to find the number of cans, c, the eighth grade collected.
5c=251−16

5c=251+16

5c+16c=251

5c+16=251

Find the missing measures for the rectangle. l = _?_ w = 4.2 m A = 37.8 m2 P = _?_ A) 9 m; 26.4 m B) 14.7 m; 61.74 m C) 9 m; 13.
egoroff_w [7]

Answer:

The correct answer is A.

Step-by-step explanation:

The area of a rectangle can be calculated using the following formula:

Ar=W . I

If we know that the area measures 37.8 m^{2} and one side of the figure measures 4.2 m, we can say that:

37.8m^{2}=4.2m. I

We isolate the side we don't know:

\frac{37.8m^{2}}{4.2m} = I\\9 m = I

So I = 9 m

To know the perimter of a rectangle, we use the following formula:

P= I. 2 + W . 2

P= 9m. 2 + 4.2m. 2

P= 26.4 m

The question is below​
Cloud [144]

Answer:

See below.

Step-by-step explanation:

a.

The first figure has 1 square. The second figure has a column of 2 squares added to the left. The third figure has a column of 3 squares added to the left. Each new figure has a column of squares added to the left containing the same number of squares as the number of the figure.

b.

Figure 10 has 1 + 2 + 3 + 4 + 5 + 6 + 7 + 8 + 9 + 10 = 55 squares.

c.

The formula for adding n positive integers starting at 1 is:

1 + 2 + 3 + ... + n = n(n + 1)/2

For figure 55, n = 55.

n(n + 1)/2 = 55(56)/2 = 1540

d.

Let's use the formula set equal to 190 and solve for n. If n is an integer, then we can.

n(n + 1)/2 = 190

n(n + 1) = 380

We know that 380 = 19 * 20, so n = 19.

Answer: yes

e.

Use the formula above,

S = n(n + 1)/2, where S is the sum.

f.

n(n + 1) = 1478

38 * 39 = 1482

37 * 38 = 1406
