Please help fast!! Katrina has $3.60 worth of nickels and dimes. She has 46 coins in total. How many nickels and dimes does she

Igoryamba

Answer:

20 nickels and 26 dimes

Step-by-step explanation:

She has $3.60 in nickels and dimes
a nickel is $0.05 and a dime is $0.10
let n be the number of nickels and d be the number of dimes
thus the first equation is 3.6 = 0.05n +0.1d
If she has 46 coins then n + d = 46
then n = 46 - d
sub n = 46 - d into 3.6 = 0.05n +0.1d
3.6 = 0.05(46 - d) + 0.1d
3.6 = 2.3 -0.05d+0.1d
1.3 = 0.05d
26 = d
sub d = 26 into n+d=46
n+26=46
n=20
Check by subbing n=20 and d=26 into 0.05n +0.1d
0.05(20) +0.1(26)
1+2.6 = 3.6

The price of tiling a room varies directly as the size of the room. Sam is laying tile in his kitchen. If the tiling costs $4,22

stiv31 [10]

Answer:

<h3>The answer is option A</h3>

Step-by-step explanation:

Let the price of the room be p

Let the size of the room be s

To find the size of a kitchen that costs $3,824.00 we must first find the relationship between them

The statement

The price of tiling a room varies directly as the size of the room is written as

where k is the constant of proportionality

when

p = $4,224.00

s = 264 square feet

Substitute the values into the expression to find k

That's

4224 = 264k

Divide both sides by 264

k = 16

So the formula for the variation is

when

p = 3824

$s = \frac{p}{16}$

$s = \frac{3824}{16}$

s = 239

The final answer is

239 square feet

Hope this helps you

What is the slope of the line shown in the graph?<br> A 3/2<br> B) 2/3<br> C) -3/4<br> D) -2/3

garik1379 [7]

Answer:

Step-by-step explanation:

y-intercept is (0, 3)

x-intercept is (4.5, 0)

formula to find the slope from two points is

$slope = m = \frac{y2 - y1}{x2 - x1} = \frac{y1 - y2}{x1 - x2} \\$

then the slope of the line that crosses (0, 3) & (4.5, 0) is

$m = \frac{3 - 0}{0 - 4.5} = \frac{3}{ - 4.5} = - \frac{3}{ \frac{9}{2} } = - \frac{2}{3}$
