Janice has three times as many dimes as nickels. If the total value of the money is $9.10, how many of each types of coin does s
ICE Princess25 [194]
X= number of nickels
3x= number of dimes

Each nickel is $0.05 and each dime is $0.10. Multiply each coins monetary value by the quantity of each. Add them equal to the total $9.10.

(0.05 * x) + (0.10 * 3x)= 9.10
multiply inside parentheses

0.05x + 0.3x= 9.10
add

0.35x= 9.10
divide both sides by 0.35x

x= 26 nickels


DIMES
3x= 3(26)= 78 dimes

CHECK:
(26 nickels * 0.05) + (78 dimes * 0.10)= 9.10
$1.30 + $7.80= $9.10
$9.10= $9.10


ANSWER: There are 26 nickels and 78 dimes.

Hope this helps! :)

The vertices of parallelogram ABCD are A(2,1),B(3,4),C(5,3), and D(4,0). ABCD is reflected over the x-axis to create parallelogr
Anna35 [415]

Answer:

The correct answer is:

D)   Q(2,1)  R(3,-4) S(5,-3) T(4,0)

Step-by-step explanation:

When you reflect over the x-axis the vertices of the parallelogram, the y -coordinates is multiplying by -1.

Then the new coordinates of the parallelogram are:

Q(2,-1)  R(3,-4) S(5,-3) T(-4,0)

Each pair of polygons is similar. Find the value of x.
Rus_ich [418]

Answer:

The value of x is 1.5

Step-by-step explanation:

<em>In similar figures, corresponding sides have the same ratio</em>

In the given figure

∵ There are 2 similar polygons

∴ We must write their names with corresponding angles

∵ ∠A = ∠L, ∠B = ∠M, ∠C = ∠N, ∠D = ∠P

∴ Their names are ABCD and LMNP

→ By using the rule above

∴ Their corresponding sides have the same ratio

∴ \frac{AB}{LM} = \frac{BC}{MN}

∵ AB = 14 and LM = x + 9

∵ BC = 10 and MN = x + 6

→ Substitute them in the ratio up

∴ \frac{14}{x+9} = \frac{10}{x+6}

→ By using the cross multiplication

∵ 14 × (x + 6) = 10 × (x + 9)

∴ 14(x) + 14(6) = 10(x) + 10(9)

∴ 14x + 84 = 10x + 90

→ Subtract 10x from both sides

∵ 14x - 10x + 84 = 10x - 10x + 90

∴ 4x + 84 = 90

→ Subtract both sides by 84

∵ 4x + 84 - 84 = 90 - 84

∴ 4x = 6

→ Divide both sides by 4 to find x

∴ x = 1.5

∴ The value of x is 1.5

This figure represents a design that is sewn onto a blanket. The semicircles are a solid green fabric and the square is a floral
mina [271]

Answer:

61%

Step-by-step explanation:

Because there are 4 semicircles, 18/4=4.5, so the area of each semicircle is 4.5 pi. Therefore the area of a whole circle is 9 pi, so the radius of the circle is 3. That means the diameter of the circle, which is also the side of the square, is 6, so the area of the square is 36. Therefore the percent of the design that is green fabric is:

18pi/18pi+36

= 56.52/92.52

= about 0.611, which rounds to 61%.
