Answer:
84 cents left over.
Step-by-step explanation:
3 quarters equals 75 cents.
2 dimes equal 20 cents.
5 nickels equal 25 cents.
So, 75 cents (The quarters) plus the 25 cents (The nickels) equals 1 dollar. At the moment, you now have 6 dollars and 20 cents (The 5 dollars in bills plus the dollar in cents is 6 dollars, then add the dimes, which is 20 cents.). So, you subtract the $6.20 - $5.36. The answer is 0.84, or 84 cents left over.

Your current exam mean is 95. If you receive a 95 on the next exam, your mean ______. a. will remain the same b. will increase c. will decrease d. cannot be determined
Answer:
will remain the same
Step-by-step explanation:
Examples:
Your current exam mean is 97.2. If you receive a 99 on the next exam, this will have the effect of: increasing your mean
Your current exam mean is 93.2. If you receive a 87 on the next exam, this will have the effect of: decreasing your mean
Therefore, Your current exam mean is 95. If you receive a 95 on the next exam,this will have the effect of: Will remain the same

The total cost, c, in dollars, of b bottles of water is c = 1. 1b. What is the constant of proportionality? Enter your answer as a decimal in the box.
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.
What is the constant of proportionality?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:
The triangles are made up from the climbing dome divided
Step-by-step explanation:
I will mark brainliest if someone can help me with this geometry question
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
Somebody help Janele! XD
quartz gym....interesting, janele
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
lol Janele and the quartz gym, some of these math problems really do be interesting. like jim and his 100 watermelons from costco

Explanation:
Multiply all terms by the same value to eliminate fraction denominators,Cancel multiplied terms that are in the denominator and Re-order terms so constants are on the left,Combine exponents
Move terms to the left side
Rearrange terms
Common factor
Divide both sides of the equation by the same term

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.

Find the value of x pls
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°

The triangle below is equilateral. Find the length of side x to the nearest tenth.
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

Find the exact value of (1 7/9)^1/2
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
