A charity organization is collecting change to raise money. They have collected three times as many dimes as quarters, 11 more n

Scrat [10]

Answer:they collected 1020 dimes, 340 quarters, 1031 nickels and 2062 pennies.

Step-by-step explanation:

Let d represent the number of dimes that they collected.

Let q represent the number of quarters that they collected.

Let n represent the number of nickels that they collected.

Let p represent the number of pennies that they collected.

They have collected three times as many dimes as quarters. It means that

d = 3q

q = d/3

The collected 11 more nickels than dimes. It means that

n = 11 + d

They collected 2 times as many pennies as nickels. It means that

p = 2n

p = 2(11 + d)

p = 22 + 2d

If they have collected a total of 4453 coins, it means that

p + q + d + n = 4453 - - - - - - - - - -1

Substituting q = d/3, n = 11 + d and

p = 22 + d into equation 1, it becomes

22+ 2d + d/3 + d + 11 + d = 4453

66 + 6d + 6d + d + 33 = 13359

13d = 13359- 99

13d = 13260

d = 13260/13

d = 1020

q = d/3 = 1020/3

q = 340

n = 11 + d = 11 + 1020

n = 1031

p = 22 + 2d = 22 + 2 × 1020

p = 2062

nikki grows 12 tomato plants. she measures their heights to the nearest centimetre, and writes them down. Complete the frequency

sdas [7]

Answer:

Nikki grows 20 tomato plants and she measures their heights.

We want to complete the frequency table.

All we have to do is count the number of values that fall between each range.

The values are:

5 10 12 16 14

17 20 15 10 7

13 11 6 18 15

6 12 17 8 12

Height Frequency

-> 5 ≤ h < 10 5

10 ≤ h < 15 8

15 ≤ h < 20 6

20 ≤ h < 25 1

A rectangular window is topped with a semicircle on top. the height of the rectangular part is 1 more than 3 times its width , w

tensa zangetsu [6.8K]

In general for a rectangle of dimensions w by h and a semicircle of diameter w we get an area:

$A = wh + \frac 1 2 \pi (\frac w 2)^2$

The halfs are because a semicircle is half a circle and a radius is half a diameter.

We're told

$h = 1+ 3w$

Substituting,

$A(w) = w(1+3w) + \frac 1 2 \pi (\frac w 2)^2$

Answer: B
