Vivian had a $5 bill, 3 quarters, 2 dime, and 5 nickels. She paid for a poster that cost $5.36. How much money does she have left

I assume you mean the mixed number 1 + 7/9.

As an improper fraction, we have

1   7/9 = 1 + 7/9 = 9/9 + 7/9 = (9 + 7)/9 = 16/9

Then the square root of this is

√(1   7/9) = √(16/9) = √(4²/3²) = √((4/3)²) = 4/3

Answer:

24

Step-by-step explanation:

Hi hi ok so heres how you do this:

This is a right triangle cause of the lil' red angle indication.

So, we use Pythagorean theorem.

a^2+b^2=c^2

Now, we have a and c(or b and c. A and B are interchangeable)

10^2+b^2=26^2

100+b^2=676

676-100=576

Now, square root of 576 is 24.

the other leg is 24

Answer:

25 cm

Step-by-step explanation:

Using the Pythagorean Theorem (a^2+b^2=c^2 FOR RIGHT TRIANGLES ONLY), you see that 10^2+b^2=26^2, and the answer is b=25 cm.

Answer:

19 i think you add them

Step-by-step explanation:

The value of the constant of proportionality in the expression c=1.1 b is 1.1.

Given to us

The total cost, c, in dollars, of b bottles of water, is c = 1.1b.

The constant of proportionality is plugged into an expression when the proportionality is been removed from the expression.

As the total cost is dependent on the number of bottles that is been purchased, therefore,

[tex]\rm{ Total\ Cost \propto\ Number\ of\ bottles}[/tex]

Removing the proportionality, we will get,

[tex]c=kb[/tex]

where c is the total cost, b is the number of bottles,

Now compare the two equations,

c = kb

c = 1.1 b

Hence, the value of the constant of proportionality in the expression c=1.1 b is 1.1.

Answer:

D

Step-by-step explanation:

So when making these equations, there's always going to be an initial value and then a variable

In this case, x represents the unknown cost for each class that Janele took at the rock climbing gym.  She took 6 classes, so that's represented by 6x

50 is the initial value.  The initial value is a value that is constant, or stays the same.  It doesn't change based on variables like how many classes she took.  

The total cost of everything was 92 dollars

So then ur equation would be

6x + 50 = 92

Because both the initial cost of 50 dollars and the cost of the classes equal to 92

Answer:

x = 18

Step-by-step explanation:

Y = 90

Z = 25
X = 3x + 11

Triangle = 180

180 = 90 + 25 + (3x + 11) --> combine 90 and 25
180 = 115 + (3x + 11) --> minus 115 both sides
65 = 3x + 11 --> minus 11 both sides

54 = 3x --> divide 3 on both sides

x = 18

VERIFY:

3(18) + 11 = 54 + 11 = 65
65 + 90 + 25 =
155 + 25 = 180

Answer:

X = 18°

Step-by-step explanation:

As we can see it a right angled triangle

so <y =90°

Now

3x + 11° + 25° + 90° = 180°{being sum of angles of triangle}

3x + 126° = 180°

3x = 54°

X = 18°

Hope it will help you

Answer:

B

Step-by-step explanation:

Since the triangle has 2 equal base angles (45 degrees) and 1 angle is 90 degrees, the triangle is an isosceles right triangle.

We let a be the length of one side of the right angle, so the length of the other side is also a. Applying the Pythagorean theorem we have a^2 + a^2 =14^2 => a=[tex]7\sqrt{2}[/tex]

We have the area of an equilateral triangle 1/2 the product of the lengths of the 2 sides of the right angle. S=1/2*[tex]7\sqrt{2} * 7\sqrt{2}[/tex]=49

Answer:

TW/UV=WX/UX
Two triangles are similar when all of their angles are equal & Ratio of side to side is equal when two triangles are similar.

Answer:

that is an equilateral triangle and if one side is 3.46 rounded it is 3.5

Step-by-step explanation:

3.5 because rounding found out by square root of 12

Answer:

x = 4[tex]\sqrt{3}[/tex] = 6.9

Step-by-step explanation:

if the large triangle is equilateral then each angle is 60°

but the altitude creates two smaller triangles that measure 30-60-90°

the ratio of sides, respectively, is 1 : [tex]\sqrt{2}[/tex] : 2

we can create a proportion to find 'x':

x/2 = [tex]\sqrt{12}[/tex]/1

cross-multiply:

x = 2[tex]\sqrt{12}[/tex]

since [tex]\sqrt{12}[/tex] = [tex]\sqrt{4}[/tex]·[tex]\sqrt{3}[/tex] = 2[tex]\sqrt{3}[/tex]

so 'x' = 2·2[tex]\sqrt{3}[/tex] = 4[tex]\sqrt{3}[/tex]

therefore, we can see that the side opposite the 30° angle is half the hypotenuse
