Answer 1

Answer:

Cameron found 23 quarters and 57 dimes.

Step-by-step explanation:

Let the number of quarters Cameron found = Q

And the number of dimes = D

Since, total number of coins were 80,

Q + D = 80 -----(1)

Total amount of the coins was $11.45,

0.1D + 0.25Q = 11.45

10D + 25Q = 1145

2D + 5Q = 229 -----(2)

Equation (1) multiplied by 2 then subtracted by equation (2),

(2D + 5Q) - 2(Q + D) = 229 - 2(80)

(2D - 2D) + (5Q - 2Q) = 229 - 160

3Q = 69

Q = 23

From equation (1),

23 + D = 80

D = 57

Cameron found 23 quarters and 57 dimes.

The answer is 63

Glad I could help :)

Answer:

117

Step-by-step explanation:

angle 2 is a vertical angle to 63. This means that it is equal to 2. So angle two is 63 degrees.

angle 2 and 7 add up to 180 degrees. You know that angle 2 is 63 degrees. So you do 180-63 degrees which leaves you with 117 degrees. Angle 7 is 117 degrees.

angle 5 and 7 are also vertical angles. Which means 5 is also equal to 117.

The answer is 117 degrees.

Answers

Answer: $29850

Step-by-step explanation:

From the question, we are informed that Kevin earned $28,500 in gross wages last year and had $1,350 in capital gains.

The amount of Kevin's income from last year that is subject to income tax will be the addition of the amount he earned and his capital gains. This will be:

= $28500 + $1350

= $29850

Step-by-step explanation:

2x + 3(4) - 1 = 47

Begin by combining your like terms

5n+17≥n–3≥–15+5n

Answers

Answer:

-5 ≤ n ≤ 3

Step-by-step explanation:

Firstly we solve the equation two at a time;

5n + 17 ≥ n - 3

5n - n ≥ -3 - 17

4n ≥ -20

n ≥ -5

-5 ≤ n

n - 3 ≥ -15 + 5n

n - 5n ≥ -15 + 3

-4n ≥ -12

-n ≥ -3

n ≤ 3

Therefore,

5n+17 ≥ n–3 ≥ –15+5n, becomes

-5 ≤ n ≤ 3

The volume of a prism is 60 cubic cm. If the height is 6 cm and the width is 2 cm, what is the length? Help me lol

Answers

*Note that I'm assuming the prism is a triangular prism

Volume = 60cm³

Height = 6cm

Width = 2cm

The equation for the volume of a triangular prism is:

V = [tex]\frac{b * h * l}{2}[/tex]

Let's substitute in the values we already know:

60 = [tex]\frac{2 * 6 * l}{2}[/tex]

And now we need to make l the subject by multiplying both sides by 2:

120 = 2 x 6 x L

Simplify:

120 = 12L

Flip to make easier to read:

12L = 120

Divide both sides by 12 to get the value of L (length):

L = 10

And let's show proof that L = 10 (remember that V (volume) should be equal to 60):

V = [tex]\frac{2 * 6 * 10}{2}[/tex]

V = [tex]\frac{120}{2}[/tex]

V = 60

Therefore we can determine the the length is indeed 10cm.

How many solutions does have?
1/2 ( 2p + 9 ) = -p + 5

Answers

Answer:

Step-by-step explanation:

P + 4.5 = - p + 5

Bringing like terms on one side

P + p = 5 - 4.5

2p = 0.5

p = 0.5/2 = 0.25

In my opinion the answer is one solution

Answer:

1 solution.

Step-by-step explanation:

1/2(2p + 9) = -p + 5

lets solve for p

1/2 * 2p + 1/2 * 9 = -p + 5

1p + p + 9/2 = - p + p + 5

2p + 9/2 = 5

Multiply by 2 on both sides to get rid of the fraction 9/2.

4p + 9 = 10

4p = 1

p = 1/4

Therefore, there is only 1 solution.

You can now check by plugging in 1/4 for p in the original equation.

Answers

Answer:

3"x4

Step-by-step explanation:

The symbol for a foot is "ft", sometimes denoted by a prime(') , also, the inch is denoted by a double prime(").

Given

2 1/2inces (2.5") blue print represents 10ft living room

We are told that the dimension of the room on the blueprint is

12'x16'

Let us convert 12' to inches

So

2.5" represents 10'

X ' will be 12'

Cross multiplying

X=(2.5*12)/10

X=3"

Let us convert 16' to inches

So

2.5" represents 10'

Y ' will be 16'

Cross multiplying

Y=(2.5*16)/10

Y=4"

the dimension of the blue print is

3"x4"

find the value of x

Answers

Answer:

           x = √70

Step-by-step explanation:

From ΔABD:

                   BD² + 7² = x²   ⇒  BD² = x² - 49

Form ΔBCD:

                   BD² + 3² = BC²   ⇒  BD² = BC² - 9

so:

       BC² - 9 = x² - 49   ⇒  BC² = x² - 40

From ΔABC:

                 x² + BC² = (7+3)²

                  x² + x² - 40 = 10²

                   2x² = 140

                    x² = 70

                    x = √70                    

Answer:

x = [tex]\sqrt{70}[/tex]

Step-by-step explanation:

Δ ABC and Δ ADB are similar, thus ratios of corresponding sides are equal, that is

[tex]\frac{AB}{AD}[/tex] = [tex]\frac{AC}{AB}[/tex] ( cross- multiply )

AB² = AC × AD = 10 × 7 = 70 ( take the square root of both sides )

AB = x = [tex]\sqrt{70}[/tex]
