Find the perimeter of a triangle with sides
10 inches, 5 inches, and 11 inches in length.

Answer:

-$45

Step-by-step explanation:

Find how much he owes his friends in total by multiplying 3 by 15:

3(15)

= 45

So, he owes his friends $45.

Since he has no money, we can find his worth by subtracting 45 from 0:

0 - 45

= -45

His worth is -$45.

Explanation:

First, let's calculate angle BYC. This is the angle formed by the chords that subtend the arcs mentioned. This angle faces or is aimed toward the direction of the arcs. To find this angle, we'll average the arc measures like so:

angle BYC = (arcAD + arcBC)/2

angle BYC = (50+120)/2

angle BYC = 170/2

angle BYC = 85 degrees

Then we'll use the idea that angles BYC and DYC are supplementary (aka they form a straight 180 degree angle)

angleBYC + angleDYC = 180

angleDYC = 180 - angleBYC

angleDYC = 180 - 85

angleDYC = 95 degrees

which is why the answer is choice D.

Answer: $864.63

Step-by-step explanation:

First find the original price. Write 20% as the decimal 0.20 before using it in the equation.

price

= cost+mark-up

= 960.70+0.20×960.70

= 960.70+192.14

= 1,152.84

The original price was $1,152.84.

Now find the discount price. Write 25% as the decimal 0.25 before using it in the equation.

discount price

= original price–discount

= 1,152.84–0.25×1,152.84

= 1,152.84–288.21

= 864.63

The discount price was $864.63.

Answer:

m + 1/4 = 2/3

Step-by-step explanation:

Since they are equal lengths set them = to each other.

2/3 - 1/4= 5/12; 1/4 + m = 2/3

We know it's subtraction as the tape diagram above has 2 pieces, both smaller than the whole tape diagram below it. Also, knowing it has 2 pieces and that 1/4 is small than 2/3 help us know that it's subtraction.

Answer:

x = 5

Step-by-step explanation:

Sum of angles = 180, so

60 + 80 + 8x = 180

140 + 8x = 180

8x = 180 - 140 = 40

x = 40/8 = 5

Answer:

check explanation

Step-by-step explanation:

in eqn 2,

y = 3 - 2x

substitute for it in eqn 1

3x² + y² = 20

3x² + (3 - 2x)² = 20

3x² + 9 - 12x + 4x² = 20

Group like terms;

3x² + 4x² - 12x = 20 -9

7x² - 12x = 11

x(7x - 12) = 11

x = 11,

OR

7x - 12 = 11

7x = 11 + 12

7x = 23

x = 23/7

x = 3.286

To get y, substitute for x in eqn 2

WHEN x = 11,

y = 3 - 2(11)

y = 3 - 22

y = -19

WHEN x = 3.286

y = 3 - 2(3.386)

y = -3.772

Answer:

the mistake is that to "remove" the 1/2 on the left you would have to multiply by 2 (or divide by 1/2 but no one does that)

the result would be that 2h-4 = 10  should actually be 2h-4 = 20

Answer:

A&C

Step-by-step explanation:

They are negative and even and they are not positive and even too.

Answer:

A

Step-by-step explanation:

Technically A and C are correct but we are dealing with only negative even values. A non-positive integer is any negative number or zero but we don't have that value so it makes more sense to choose A than C. B is incorrect because a whole number can't include a negative number, a fraction, or a decimal. D is also incorrect because a non-negative integer is a positive number which we don't have in the set.

Answer:

95kg

Step-by-step explanation:

Mass÷Volume=Density

Therefore, Mass = Volume × Density

Mass = 1500 × 95

Mass = 95,000g

Since we were asked to find the mass in kg:

1000g = 1kg

Therefore, 95,000g = 95kg

Answer:

Step-by-step explanation:

The ratio if the number if books to the cost in dollars is 1 : 4

To plot on a coordinate grid, we first look at the horizontal direction (x-axis)

Take the number of books to be values of the x-coordinate.

Start at the origin and travel the necessary distance to the left or the right then move up or down in the vertical direction to mark the y-coordinate.

The corresponding cost to be the values of the y-coordinate. Mark or plot at the intersection of the two numbers.

Answer:

0.5t + 0.25(t +16) =4 + 0.75t

0.5t + 0.25t + 4 = 4 + 0.75t

0.5t+ 0.25t – 0.75 t = 4– 4

0.5t +0.25t–0.75t = 0 —> 0 = 0

I hope I helped you^_^

Answer: All Real Numbers or A.R.N

Step-by-step explanation:

Given

0.5t + 0.25 (t + 16) = 4 + 0.75t

Expand parentheses and apply the distributive property

0.5t + 0.25 · t + 0.25 · 16 = 4 + 0.75t

0.5t + 0.25t +4 = 4 + 0.75t

Combine like terms

0.75t + 4 = 4 + 0.75t

Subtract 0.75t on both sides

0.75t + 4 - 0.75t = 4 + 0.75t - 0.75t

4 = 4

Since both sides are left with the same term, this means any number would be able to make the equation true.

Therefore the answer would be All Real Numbers, or [tex]\boxed{A.R.N}[/tex]
