Answer:

$8 ; 66 cents

Step-by-step explanation:

Given that:

Worth of penny, dimes and Nickel in cents and dollars

Nickel, n = 5 cents = $0.05

Dimes, d = 10 cent = $0.1

Penny, p = 1 cent = $0.01

Multiplying the number of each coin with its respective value ;

386(0.01) + 58(0.05) + 19(0.1)

$3.86 + $2.9 + $1.9

= $8.66

Changing it to dollar ,

$8.66 dollars = 8 dollars ;

$0.66 = 66 cents

Answer:

[tex]3\sqrt{5}[/tex]

Step-by-step explanation:

Since the triangle has a right angle, we are going to use pythaogoran theoem, which is [tex]a^{2} +b^{2} =c^{2}[/tex], where a and b are the legs and and c is the hypotunese/ slated side.  Let set it up.

[tex]3^{2} +6^{2} =c^{2}[/tex]

9+36=c^2

45=c^2

[tex]\sqrt{45}[/tex]=

Then we are going to find a perfect squarre root(1,4,9,16,25....) to simplify the radical

The perfect square root is 9 because 9 goes into 45 5 times.

[tex]\sqrt{9x5}[/tex]

Then take the sqr root of 9 and we have [tex]3\sqrt{5}[/tex]

Answer:

Step-by-step explanation:

1. The first ski was valued at $850 but was then given a 50% discount. The sales price will therefore be:

= 850 * ( 1 - 50%)

= 850 * 50%

= $425

2. The first one was first discounted by 30% so the sales price was:

= 850 * ( 1 - 30%)

= 850 * 70%

= $595

It was then marked down by a further 20%:

= 595 * ( 1 + 20%)

= $476

3. The first ski is a better option because the discount makes it cheaper than the second ski even after the second ski had been discounted twice.

Answer:

Shampoo one is a better buy

Step-by-step explanation:

Step one:

given data

The 16 fl oz. Cost $6.19 and

The 13.5 fl oz. Cost $ 3.99

Required

The better buy/ unit cost

Step two:

shampoo one

unit cost = 16/6.19

=$2.58 per fl oz

shampoo two

unit cost = 13.5/3.99

=$3.38 per fl oz

9514 1404 393

Explanation:

The quadrilateral is a parallelogram if the midpoints of its diagonals are the same point. That is, if ...

  (N +Q)/2 = (P +R)/2

Multiplying by 2, we can simplify the test to ...

  N +Q = P +R

  (5, 1) +(6, 9) = (2, 7) +(9, 3)

  (5+6, 1+9) = (2+9, 7+3)

  (11, 10) = (11, 10) . . . . . . . true ∴ NPQR is a parallelogram

Answer:

100(x-3)

Answer:

4.95 * 20 = 99 your earnings

4.25 * 20 = 85 friends earnings

Step-by-step explanation:

44.55/9 = hourly earnings

                4.95 per hour

51/12= hourly earnings

                    4.25 per hour

4.95 * 20 = 99 your earnings

4.25 * 20 = 85 friends earnings

Answer:

emily 37.44$ Andy 22.15$

Step-by-step explanation:

Andy needs 23 feet multiply 23 feet by 12 you get the amount of inches so 276 inches if the cost for 130 inches is 10.40 we need to increase this number proportionally to 276 So 130+113%=276.9 so 276. Now 10.40x113%=22.15.

Emily needs 13 yards, 13 yards is 39 feet, 39 feet is 468 inches, Now do same thing we did for Andy. 130+360%=468 exactly 10.40+360%=37.44

Answer: 10 nickels

Step-by-step explanation:

A pennie is a cent or $0.01. Serenity has 12 pennies so the amount she has from pennies is:

= 12 * 0.01

= $0.12

The amount she has in nickels at most is therefore:

= 0.66 - 0.12

= $0.54

A nickel is $0.05 so the number of nickels are:

= 0.54/0.05

=  10.8 nickels

= 10 nickels

If she has 10 nickels then the total she would have is:

= (12 * 0.01) + (10 * 0.05)

= $0.62

This fits the parameters

Answer:

D. The amount of NO2 and SO2 would increase.

Step-by-step explanation:

This is an exothermic reaction as Heat is among the products. Increasing the temperature would lead to more products in the reaction system. In order for the system to annul this change, more reactants would be formed.

The correct option is;

D. The amount of NO2 and SO2 would increase.

Answer:

76

Step-by-step explanation:

To find the area you multiply both sides, the opposite of multiplication is division. Take 6992 and divide it by 92 to get the missing side of 76.

Answer:

P=12

Step-by-step explanation:

Answer:

1:u

Step-by-step explanation:

Grey slabs = 1/5 of total slab

Say total slab = x

Then,

Grey slabs = 1x/5

We can represent

Yellow slabs = u/5

Then ratio of Grey to yellow would be;

Gray slabs / Yellow slabs = (1x/5)/(u/5)

=1/u

= 1:u

Since there are 55 slabs in total, then

Yellow slab would be = 55/5 = 11

Answer:

We conclude that:

f(g(-2)) = -3

Step-by-step explanation:

Given

To determine

In order to determine f(g(-2)), first we need to determine g(-2)

so substituting x = -2 in g(x) = x-3

g(-2) = -2 - 3

        = -5

Thus,

f(g(-2)) = f(-5)

now substitute x = -5 in the function f(x) = 2x+7

f(x) = 2x+7

f(-5) = 2(-5) + 7

f(-5) = -10 + 7

f(-5) = -3

so

f(g(-2)) = f(-5) = -3

Therefore, we conclude that:

f(g(-2)) = -3

Answer:

The missing base b is 3 units

Step-by-step explanation:

Let us solve the problem

In the given figure

∵ The given figure is a parallelogram

∵ The line of length 7 is perpendicular to the base that parallels to base b

∵ The base b has a height of 7 units

→ By using the formula of the area above

∵ A = b1 × h1

∵ b1 = b and h1 = 7 units

∵ The parallelogram has an area of 21 square units

∴ A = 21

→ Substitute the value of A and h in the rule of the area

∵ 21 = b × 7

∴ 21 = 7b

→ Divide both sides by 7

∴ 3 = b

∴ The missing base b is 3 units
