pls help me with this math problem

Answer:

Most 1995 pennies in circulated condition are only worth their face value of $0.01. These coins can only sell for a premium in uncirculated condition. The 1995 penny with no mint mark and the 1995 D penny are each worth around $0.30 in uncirculated condition with an MS 65 grade.

Answer:

by 6

Step-by-step explanation:

Isolate x for x + 2y= 11: x= 11- 2y

Substitute x =11 -2y

6(11 - 2y) + 4y = 34|

Simplify

[66 -8y= 34]

Isolate y for 66 - 8y= 34: y =4

For x = 11 - 2y

Substitute y = 4

X= 11-2 x 4

Simplify

X=3

The solutions to the system of equations are:

X=3,y=4

Answer:

3

Step-by-step explanation:

Y intercept when x = 0

F(0) = 3 * 4^(0) = 3 * 1 = 3

[tex]~~~~(11.2)^2\\\\=(11+0.2)^2\\\\=11^2 + 2(11)(0.2) + (0.2)^2\\\\=121+4.4+0.04\\\\=125.44[/tex]

Hey there!

11.2^2

= (11.2)^2

= 11.2 * 11.2

= 125.44

Therefore, the answer should be: 125.44

Good luck on your assignment & enjoy your day!

Answer:

it would be 59.5

Step-by-step explanation:

let's be more detailed than the other answer :

the perimeter is the sum of all sides of an object. in case of a triangle, well, that is the sum of all 3 sides.

so,

25 = x + (x-5) + (x+3) = x + x - 5 + x + 3 = 3x - 2

27 = 3x

x = 9

so, the sides are

x = 9 cm

(x-5) = 9 - 5 = 4 cm

(x+3) = 9 + 3 = 12 cm

Answer:

⅜ is the distance

Answer:

(1, 2)

Step-by-step explanation:

Hi there!

We are given two points - (4, 7) and (-2, -3)

We want to find the midpoint between these two points

The midpoint can be found using the formula [tex](\frac{x_1 + x_2}{2}, \frac{y_1+y_2}{2})[/tex], where [tex](x_1, y_1)[/tex] and [tex](x_2, y_2)[/tex] are points

We have everything we need to find the midpoint, but let's label the values of the points to avoid any confusion & mistakes

[tex]x_1=4\\y_1=7\\x_2=-2\\y_2=-3[/tex]

Now substitute into the formula

[tex](\frac{x_1 + x_2}{2}, \frac{y_1+y_2}{2})[/tex]

[tex](\frac{4+ -2 }{2}, \frac{7+-3}{2})[/tex]

The pluses can be replaced with minus signs:

[tex](\frac{4 -2 }{2}, \frac{7-3}{2})[/tex]

Now subtract

[tex](\frac{2 }{2}, \frac{4}{2})[/tex]

Divide

(1,2)

The midpoint is (1, 2)

Hope this helps!

Answer:

6 Miles

Step-by-step explanation:

What do we know: Linda hiked 10 miles last weekend, and she plans to walk 3/5ths of that next weekend.

Thus, we take 10 and multiply it by 3/5.

To understand it all better, let's write the equation like this, X will be the number of miles Linda plans to hike next weekend.

[tex]\frac{10}{1}[/tex]×[tex]\frac{3}{5}[/tex] = [tex]\frac{30}{5}[/tex]

Afterwards we can simplify like so, factoring 5 from both the numerator and the denominator:

[tex]\frac{5(6)}{5(1)}[/tex]

The 5's in the numerator and denominator cancel out, leaving us with:

[tex]\frac{6}{1}[/tex]

Or in simpler terms 6. Thus we can know that Linda will hike 6 miles next weekend.

Answer: 540 cm³

Step-by-step explanation:

    The volume of a rectangular prism can be found with:

V = L * W * H

-> L is the length

-> W is the width

-> H is the height

V = L * W * H

V = 18 cm * 7.5 cm * 4 cm

V = 540 cm³

         The volume is 540 cm³.

Answer: Select 2 because its 2 times the volume of cone

Step-by-step explanation:

Answer:

a = 24

Step-by-step explanation:

a - 1.5 = 22.5

a = 24

you can plug it into the other 2 to make sure it is right my brain hurts so i won't.

Have a nice day! :) and btw people will think it is a scam because 2 answers are allowed right so the points split in half and the person answering will only get 10 points

Answer:

14

Step-by-step explanation:

We can find the sum of these numbers by adding them together.

The cumulative rule of addition lets us add numbers together in any order we want.

So, for 2 + 3 + 4 + 5 …

2 + 3 = 5

So now we have 5 + 4 + 5

5 + 4 = 9

Now we have 9 + 5

And 9 + 5 = 14

So, your answer is 14

Answer:

x = 6

Step-by-step explanation:

To find x we set up an  equation as so:

[tex]\frac{4.5}{x} =\frac{6}{8}[/tex]

Then we solve by multiplying 4.5 by 8 and 6 by x

[tex]6x=36[/tex]    Solve for x

[tex]\frac{6x}{6} =\frac{36}{6}[/tex]    x = 6

To check our answer when we substitute x or 6 we divide to make sure both sides equal the same number

[tex]\frac{4.5}{6} =\frac{6}{8}[/tex]    when divided both equals 0.75

Answer:

9

Answer:

9 miles

Step-by-step explanation:

Given scale:  2 in = 3 miles

⇒ 1 in = 1.5 miles

If the width of the plot of land is 6 inches, then to calculate the actual width multiply 6 by 1.5:

actual width = 6 × 1.5 = 9 miles

Answer:

[tex]1\frac{1}{5}[/tex]

Step-by-step explanation:

6/5

= 1 1/5

Answer:

[tex]1\frac{1}{5}[/tex]

Step-by-step explanation:

First, we do 6 / 5 = 1.2. We do this because we are sharing 6 cups with 5 friends - we are dividing 6 cups between 5 friends.

So, each friend will get 1.2 cups. But, the question is asking for a fraction. 0.2 is the same as [tex]\frac{1}{5}[/tex], so each person will get [tex]1\frac{1}{5}[/tex]

Alternatively, you could do [tex]\frac{6}{5} = 1\frac{1}{5}[/tex]

Hope this makes sense.
