Which equation can be used to solve the following word problem? Seth has 8 more nickels than dimes, and the total value of his c

9966 [12]

Answer:

Seth has 21 nickels

Step-by-step explanation:

Let n represent the number of nickels. Since Seth has 8 more nickels than dimes, then (n-8) is the number dimes.

Nickel is worth 5 cents and dime is worth 10 cents. Thus, n nickels are worth 5n cents and (n-8) dimes are worth 10(n-8) cents. The total value of Seth's coins is $2.35 that is 235 cents, then

$5n+10(n-8)=235.$

Solve this equation:

$5n+10n-80=235,\\ \\15n=235+80,\\ \\15n=315,\\ \\n=21.$

Camille stopped at the grocery store to buy milk. While at the store, she spotted cans of soup on sale for $2.25 each. If the mi

Mrrafil [7]

$2.25x+$3.50=$35

so, $35-$3.50=$31.50

Then you divide $31.50 by $2.25

That equals 14

So, x=14

By what percent will the fraction change if its numerator is increased by 25% and its denominator is increased by 20%? please an

d1i1m1o1n [39]

<h2>Answer:</h2><h2>The new fraction will chnage by 1.25 : 1.2 ratio, (i.e) = 1.04 %</h2>

Step-by-step explanation:

Let the fraction be represented as $\frac{x}{y}$ where x is the numerator and y is the denominator

Given that numerator will increase by 25 %, = 25% x

= 0.25 x

Given that denominator will increase by 20 %, = 20% y

= 0.2 y

The new fraction becomes = $\frac{x + 0.25 x}{y + 0.2 y}$

= $\frac{1.25 x}{1.2 y}$

= $(\frac{1.25}{1.2} ) \frac{x}{y}$

The new fraction will chnage by 1.25 : 1.2 ratio, (i.e) = 1.04 %

A point charge q1 = 3.30nC is located on the x-axis at x= 1.90m , and a second point charge q2= -6.40 nC is on the y-axis at y=

Dahasolnce [82]

Answer:

Step-by-step explanation:

charge q1 is placed at x = 1.90 m and the charge q2 is placed at y = 1.15 m

here, the charge enclosed in a sphere is zero as the radius of sphere is 0.625 m which is less than the x = 1.90 m and y = 1.15 m. So by the Gauss's theorem,

$\phi =\frac{q}{\epsilon _{0}}$

where q is the charge enclosed, as the charge enclosed is zero so the electric flux is zero.
