Answer:

18 nickels and 35 dimes

Step-by-step explanation:

4.40

35 dimes

$3.50

4.40-3.50=0.9

0.9/ 0.05= 18 nickels

There would be 35 dimes and 18 nickels.

A collection of nickels and dimes is worth $4.40. There are 53 coins in all. How many nickels are there?

Nickel is a US coin worth 5 cents or 0.05.
Dime is a US coin worth 10 cents or 0.10

n + d = 53
0.05n + 0.10d = 4.40

n = 53 - d
0.05(53 - d) + 0.10d = 4.40  
2.65 - 0.05d + 0.10d = 4.40
0.05d = 4.40 - 2.65
0.05d = 1.75
d = 1.75 / 0.05
d = 35

n = 53 - d
n = 53 - 35
n = 18 

There are 18 nickels and 35 dimes.

0.05n + 0.10d = 4.40
0.05(18) + 0.10(35) = 4.40
0.90 + 3.5 = 4.40
4.40 = 4.40

Varvara68 [4.7K]

Answer:

2036.75088022^{2} or 2036.8^{2} rounded to the nearest tenth

Step-by-step explanation:

1. Find the area of the base and the top, which are circles.

Area of circle : \pi 10^{2} = 986.960440109

There are 2 circles, soooooo....= 986.960440109 x 2 = 1973.92088022

2. Find the rest of the area of the cylander.

So, we have to find the circumference of the circle.

Circumference :2\pi10 = 62.83

3. Multiply circumference by height.

62.83 x 7 = 439.81

4. Add all of the products.

439.81 + 1973.92088022 = 2036.75088022^{2} or 2036.8^{2} rounded to the nearest tenth

Write a equation of the lines passes through the given points (-2,7) (1,1) the equation is?
vredina [299]

The point-slope form:

y-y_1=m(x-x_1)

m - slope

(x₁, y₁) - point

The formula of a slope:

m=\dfrac{y_2-y_1}{x_2-x_1}

We have the points (-2, 7) and (1, 1). Substitute:

m=\dfrac{1-7}{1-(-2)}=\dfrac{-6}{3}=-2

y-7=-2(x-(-2))\\\\\boxed{y-7=-2(x+2)}   <em>point-slope form</em>

\boxed{y=-2x+3}     <em> slope-intercept form</em>

\boxed{2x+y=3}       <em>standard form</em>
