A boy has only dimes and quarters in his piggy bank. If he has 90 coins worth 12 dollars and 60 cents altogether, how many quarters does he have in his bank? A) 24 B) 25 C) 21 D) 22 E) 23

Answer:

a loss of 72.47

Step-by-step explanation:

I got this answer right on my test

Answer:

1. $85

2. $90.10

3.$108.12

4.$54.06

Step-by-step explanation:

100-15=85 (15% of 100 is 15)

6 percent of 85 is 5.10. So 85 + 5.10=90.10

20 percent of 90.10 is 18.02. So add that to the total. 90.10+18.02=108.12

Now divide by 2 to get how much they each will pay 108.12/2 = 54.06

x=12 perimeter=58

Answer:

(2, 12)

Step-by-step explanation:

x + 10 = 4x + 4

   - 4           - 4

x + 6 =  4x

- x         - x

6 = 3x

divide 3 on each side

2 = x

then plug 2 in either equation

ei) y = 2 + 10

    y = 12

Answer:

75

Step-by-step explanation:

With reference angle 53°

base (b) = 45

hypotenuse (h) = K

Now

cos 53° = b / h

0.6 = 45 / K

K = 45 / 0.6

K = 75

Answer:

You multiply it like normal numbers. But when you do, count how many numbers are behind the decimal, say there are 2 numbers behind the decimal, once you finished multiplying the numbers you would add up all the products you got and then put the first 4 numbers you wrote behind the decimal to get the final product.

Step-by-step explanation:

Say you were multiplying 14.63 and 7.74

                   14.63

                   x 7.74                 Always starting from the right side of the equation

                   .5852                go to the left four digits and put a decimal then                  

                  ↑←←←←                just carry the decimal down and you'll  end up with  

                 10.2410              the final product

            + 102.4100                

               113.2362

Answer:

127.253 m^3

Step-by-step explanation:

To find the volume, we start by getting the area of the square base

Mathematically, that will be 4.9^2 m^2

To complete the volume, we multiply the area of the base by the height

= 4.9^2 * 5.3 = 127.253 m^3

Answer:

16.7 years

Step-by-step explanation:

Answer:

2(4.5+4.3)=2×8.8= 17.6 mm

[tex] \frac{4.5}{4.3} = \frac{24.3}{x} \\ x = \frac{24.3 \times 4.3}{4.5} \\ \boxed{x = 23.22 \: mm}[/tex]

2(24.3+23.22)= 2×47.52= 95.04 mm

Answer:

x = 4.5 AND x = -4

Step-by-step explanation:

for the first answer

add 9 to 0 and divide by 2

for the second answer

subtract 4

Answer:

x = 9/2 and x = -4

Step-by-step explanation:

you can set each expression in the parenthesis' equal to zero. this is due to it being multiplication so if one parenthesis equals 0, the answer will be 0

2x - 9 = 0 and x + 4 = 0

starting with 2x-9=0

add 9 to both sides

2x = 9

divide by 2

x = 9/2

then do x + 4 = 0

subtract 4

x = -4

so your two answers are

x = 9/2 and x = -4

Answer:

option 2

Step-by-step explanation:

QR = 15 ( triangle is a 8- 15- 17 Pythagorean triple )

cosP = [tex]\frac{PR}{PQ}[/tex] = [tex]\frac{8}{17}[/tex] ≠ [tex]\frac{8}{15}[/tex]

tanQ = [tex]\frac{PR}{QR}[/tex] = [tex]\frac{8}{15}[/tex] ≠ [tex]\frac{15}{8}[/tex]

sinP = [tex]\frac{QR}{PQ}[/tex] = [tex]\frac{15}{17}[/tex] ≠ [tex]\frac{8}{17}[/tex]

cosQ = [tex]\frac{QR}{PQ}[/tex] = [tex]\frac{15}{17}[/tex] ← correct statement

Answer:

its the cos q = 15/17

Step-by-step explanation:

cos q = 15 (adjacent) / 17 (hypothenuse)

Answer:

x = 5

Step-by-step explanation:

4x + 3 = 23

Subtract 3 from both sides;

4x = 20

Divide both sides by 4;

x = 5

Answer:

x=5

Step-by-step explanation:

4x+3=23

4x=23-3

4x=20

x=20/4

x=5
