A youth organization collected nickels and dimes for a charity drive. By the end of the 1-day drive, the youth had collected $63

uysha [10]

Let, the numbers of nickels be x.

Given, there were 5 times as many dimes as nickels.

So, the number of dimes = 5x

We know that 1 nickel = $(0.05)

So x nickels = $(0.05x)

Also we know that 1 dime = $(0.1)

So 5x dimes = $(0.1 ×5x) = $(0.5x)

Given total value of dimes and nickels at the end of day 1 is $63.80

So we can write the equation

$0.05x+0.5x = 63.80$

$0.55x = 63.80$

Now we to find x, we have to move 0.55 to the other side. As 0.55 is multiplied there so to move it we need to divide it to both sides.

$0.55x/0.55 = 63.80/0.55$

$x = 116$

So we have got the number of nickels = 116

Number of dimes = 5x = 5(116) = 580

So we have got the required answer.

Number of nickels = 116, number of dimes = 580.

Name the place of the highlighted digit. then write the value of the digit 35.052

AysviL [449]

Solution:

Given: 35.052

The standard form is: 35.052

3 is in the tens place. 3 = 3 × 1

5 is in the tens place. 5 = 5 × 1

0 is in the tenths place. 0.0 = 0 × 1/10

5 is in the tenths place. 0.05 = 5 × 1/100

2 is in the tenths place. 0.002 = 2 × 1/1000

Each base in this right prism-like figure is a quarter of a circle with a radius of 2m.

NISA [10]

Answer:

$volume = 10\pi m^3$

Step-by-step explanation:

Volume of a prism = Base Area x height

Base is a quarter of a circle.

$Area \ of \ circle = \pi r^2\\\\r = 2m\\\\Area \ of \ quarter \ of \ a \ circle = \frac{1}{4} \pi r^2 = \frac{1}{4}\pi \times 4 = \pi m^2$

Base Area = π square meters.

Therefore ,

$Volume = Base Area \times height = \pi \times 10 = 10\pi m^3$

Which eqation is equivalent to 3x + 4y = 15

liubo4ka [24]

Answer:

$y=\frac{15-3x}{4}$

Step-by-step explanation:

Here we are given an equation in x and y and we are required to solve it for y

we have

$3x+4y=15$

subtracting 3x from each sides we get

$3x-3x+4y=15-3x$

$4y=15-3x$

now we divide both sides by 4 we get

$\frac{4y{4}=\frac{15-3x}{4}$

$y=\frac{15-3x}{4}$

Hence A) is our right answer.
